1 meter = 1000 millimeter

Answer: :)

Step-by-step explanation:

The metric system is based on the International System of Units (SI), which is a standardized system of measurement used worldwide. The SI unit for length is the meter, and all other units of length in the metric system are derived from it.

The relationship between millimeters and meters can be expressed mathematically as follows:

1 mm = 0.001 m

1 m = 1000 mm

This means that if you have a length measurement in millimeters, you can convert it to meters by dividing by 1000. Conversely, if you have a length measurement in meters, you can convert it to millimeters by multiplying by 1000.

For example, if you have a piece of wire that measures 500 mm long, you can convert this to meters as follows:

500 mm ÷ 1000 = 0.5 m

Similarly, if you have a piece of fabric that measures 2.5 m long, you can convert this to millimeters as follows:

2.5 m x 1000 = 2500 mm

In summary, the relationship between millimeters and meters is that they are both units of length in the metric system, with one meter being equal to 1000 millimeters.

Nicole has 8 nickels and 7 dimes.

A system of equations is simply two or more equations that share the same variables.

Let's use a system of equations to solve this problem:

Let x be the number of nickels, and y be the number of dimes.

From the problem, we know that:

x + y = 15 (equation 1) (the total number of coins is 15)

0.05x + 0.1y = 1.1 (equation 2) (the total value of the coins is $1.10)

To solve for x and y, we can use substitution or elimination. Let's use elimination:

Multiply equation 1 by 0.1:

0.1x + 0.1y = 1.5 (equation 3)

Subtract equation 3 from equation 2:

0.05x = 0.4

x = 8

Substitute x = 8 into equation 1:

8 + y = 15

y = 7

Therefore, Nicole has 8 nickels and 7 dimes.

Answer:

∠M = ∠P = 112

∠N = ∠Q = 68

Step-by-step explanation:

The interior angles of a quadrilateral always sum up to 360°.

since NP//MP and NM//PQ => ∠N = ∠Q and ∠M = ∠P

and ∠N + ∠Q + ∠M + ∠P = 360

∠M = ∠P

6x - 2 = 4x + 36

6x - 4x = 36 + 2

2x = 38

x = 38/2 = 19

=> ∠M = ∠P = 4(19) + 36 = 112

∠N + ∠Q + ∠M + ∠P = 360

2∠N + 2∠M = 360

∠N + ∠M = 180

∠N = 180 - ∠M = 180 - 112 = 68

∠N = ∠Q = 68

The value of the variable x for the similar triangles is equal to 3

The triangles PTQ and STR are similar, this implies that the length ST of the smaller triangle is similar to the length PT of the larger triangle

so;

5/(2x + 9) = 7/(3x + 12)

5(3x + 12) = 7(2x + 9) {cross multiplication}

15x + 60 = 14x + 63

Zach still has to save 1/12 of the total amount after this month.

To find out how much of the total amount Zach still has to save after this month, we need to calculate how much he has already saved and how much he will save from this month's paycheck.

First, we know that Zach has already saved 2/3 of the money he will need for his trip. So, if we let x be the total amount he needs for the trip, we can write this as:
Already saved = 2/3 * x

Next, we know that Zach plans to put aside 3/4 of what he has left to save from this month's paycheck. Since he has already saved 2/3 of the total amount, he has 1/3 of the total amount left to save. So, the amount he will save from this month's paycheck is:
Amount from paycheck = 3/4 * (1/3 * x) = 1/4 * x

Now, we can add these two amounts to find out how much Zach has saved in total:
Total saved = Already saved + Amount from paycheck
Total saved = (2/3 * x) + (1/4 * x) = (8/12 * x) + (3/12 * x) = 11/12 * x

Finally, we can subtract this amount from the total amount he needs to find out how much he still has to save:
Amount still to save = Total amount - Total saved
Amount still to save = x - (11/12 * x) = (12/12 * x) - (11/12 * x) = 1/12 * x

So, Zach still has to save 1/12 of the total amount after this month.

Answer:

Q1    Value of  angle B = 50°

Q2   BC =  1.3

Q3    AB = 2.57

Step-by-step explanation:

For Part 1
The three angles of  a triangle must add up to 180°

Therefore m∠B + 30 + 100 = 180

m∠B + 130 = 180

m∠B = 180 - 30 = 50°

part 2
The law of sines states that, in  a triangle, the ratio of each side to the sine of the angle opposite that side must be the same for all sides

We have side AC opposite ∠B

AC = 2 and we found that m∠B = 50° from part 1

The side BC is opposite ∠A which is 30°

Therefore, applying the law of sines
[tex]\dfrac{{AC}}{\sin 50^\circ} = \dfrac{{BC}}{\sin 30^\circ}\\\\\\\dfrac{2}{\sin 50^\circ} = \dfrac{{BC}}{\sin 30^\circ}\\\\[/tex]

Multiplying both sides by sin 30° we get
[tex]\dfrac{2}{\sin 50^\circ} \times \sin 30^\circ =BC\\\\or\\\\BC = \dfrac{2}{\sin 50^\circ} \times \sin 30^\circ[/tex]

Using a calculator to compute the right side we get
BC = 1.30540 ≈ 1.3

part 3

Similarly
[tex]\dfrac{AB}{\sin 100} = \dfrac{2}{\sin50}\\\\AB = \sin 100 \times \dfrac{2}{\sin 50} = 2.57115 \approx 2.57[/tex]

Answer:

Step-by-step explanation:

We have RO parallel to LF

Segments RF and LO are transversal segments

For two parallel lines intersected by a transversal , the alternate interior angles are equal

In this figure, there are two pairs of alternate interior angles

∠O and ∠L form one pair and are equal
∠R and ∠F form another pair and are equal

Since the point T is formed by the intersection of two straight line segments,  the vertically opposite angles must be equal
m∠RTO = m∠LTF

So in the two triangles, ΔRTO and Δ FTL we have

m∠R = m∠F
m∠O = m∠L
m∠RTO = m∠LTF

By the AAA theorem of similarity of angles the two triangles are similar

AAA Similarity Criterion for Two Triangles

The Angle-Angle-Angle (AAA) criterion for the similarity of triangles states that “If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar”.

The new function after the parent function f(x)=2^(x) is horizontally shrunk by a factor of two, translated right by 10 and translated 5 units down is f(x) = 2^((x-10)/2) - 5.

- Horizontal shrink by a factor of two: This means that the x-value of each point on the graph will be divided by 2. To achieve this, we can multiply the x-value inside the function by 1/2, or divide it by 2. So, the function becomes

f(x) = 2^((x/2))

- Translation right by 10: This means that the entire graph will shift 10 units to the right. To achieve this, we can subtract 10 from the x-value inside the function. So, the function becomes

f(x) = 2^((x-10)/2)

- Translation 5 units down: This means that the entire graph will shift 5 units down. To achieve this, we can subtract 5 from the entire function. So, the function becomes

f(x) = 2^((x-10)/2) - 5

Therefore, the new function is f(x) = 2^((x-10)/2) - 5

Yes, the binomial 2x+3 is a factor of the given polynomial P(x)=2x^(3)+3x^(2)-2x-3. We can verify this by using synthetic division.

First, we need to find the zero of the binomial, which is -3/2. Then, we can use synthetic division to divide the polynomial by the binomial.

Here are the steps for synthetic division:

1. Write the coefficients of the polynomial in a row: 2  3  -2  -3
2. Write the zero of the binomial to the left of the row: -3/2 | 2  3  -2  -3
3. Bring down the first coefficient: -3/2 | 2  3  -2  -3
               0  -3   6  -6
               ---------------
               2  0   4   -9
4. Multiply the zero by the first coefficient and write the result below the second coefficient: -3/2 * 2 = -3
5. Add the second coefficient and the result: 3 + (-3) = 0
6. Repeat steps 4 and 5 for the remaining coefficients: -3/2 * 0 = 0, -2 + 0 = -2; -3/2 * -2 = 3, -3 + 3 = 0
7. The final row of numbers represents the coefficients of the quotient: 2x^(2) + 0x + 4, with a remainder of -9.

Since the remainder is not zero, the binomial is not a factor of the polynomial. However, if we divide the polynomial by the binomial using long division, we get the following:

2x^(2) + 4 - (9/(2x+3))

This means that the polynomial can be written as: P(x) = (2x+3)(2x^(2) + 4) - 9

So, the binomial 2x+3 is a factor of the polynomial P(x)=2x^(3)+3x^(2)-2x-3.

The solution of the exponential equation is x = 0.35

An exponential equation is an equation that contains exponents.

Since we have the exponential equation

4ˣ = 8ˣ - 1

We proceed to solve as follows

4ˣ = 8ˣ - 1

(2²)ˣ = (2⁴)ˣ - 1

(2ˣ)² = (2ˣ)⁴ - 1

Let 2ˣ = y

So, we have that

y² = y⁴ - 1

Re- arranging, we have that

y⁴ - y² - 1 = 0

Also, let y² = p. So, we have that

p² - p - 1 = 0

Now, we find p using the quadratic formula.

[tex]p = \frac{-b +/-\sqrt{b^{2} - 4ac} }{2a}[/tex]

where a = 1 b = -1 and c = -1

So, [tex]p = \frac{-(-1) +/-\sqrt{(-1)^{2} - 4(1)(-1)} }{2(1)}\\= \frac{1 +/-\sqrt{1 + 4} }{2}\\= \frac{1 +/-\sqrt{5} }{2}\\p = \frac{1 + 2.24 }{2} or p = \frac{1 - 2.24 }{2}\\p = \frac{3.24 }{2} or p = \frac{-1.24 }{2}\\p = 1.62 or p = -0.62[/tex]

We ignore the negative value.

So, p = 1.62

y² = 1.62

y = ±√1.62

y = ±1.273

Since y = 2ˣ, we have that

2ˣ = ±1.273

We ignore the negative value since the value of y cannot be negative.

So, 2ˣ = 1.273

Taking natural logarithm of both sides, we have that

㏑2ˣ = ㏑1.273

x㏑2 = ㏑1.273

x = ㏑1.273/㏑2

d. The probability that the sample mean will be between $120 and $160 is 0.9356.

e. The symmetrical interval that includes 95% of the sample means is ($116.11, $153.31).

a. The standard error of the mean is calculated using the formula:

SE = σ / √n

where σ is the standard deviation and n is the sample size.

In this case, σ = $30 and n = 10. So, the standard error of the mean is:

SE = 30 / √10

SE = 9.49

b. To find the probability that the sample mean will be less than $125, we need to calculate the z-score:

z = (x - μ) / SE

where x is the sample mean, μ is the population mean, and SE is the standard error of the mean.

In this case, x = $125, μ = $134.71, and SE = 9.49. So, the z-score is:

z = (125 - 134.71) / 9.49

z = -1.02

Using a z-table, we find that the probability of getting a z-score less than -1.02 is 0.1539. So, the probability that the sample mean will be less than $125 is 0.1539.

c. To find the probability that the sample mean will be more than $145, we need to calculate the z-score:

z = (x - μ) / SE

where x is the sample mean, μ is the population mean, and SE is the standard error of the mean.

In this case, x = $145, μ = $134.71, and SE = 9.49. So, the z-score is:

z = (145 - 134.71) / 9.49

z = 1.08

Using a z-table, we find that the probability of getting a z-score less than 1.08 is 0.8599. So, the probability that the sample mean will be more than $145 is 1 - 0.8599 = 0.1401.

d. To find the probability that the sample mean will be between $120 and $160, we need to calculate the z-scores for both values:

z1 = (x1 - μ) / SE

z2 = (x2 - μ) / SE

where x1 and x2 are the sample means, μ is the population mean, and SE is the standard error of the mean.

In this case, x1 = $120, x2 = $160, μ = $134.71, and SE = 9.49. So, the z-scores are:

z1 = (120 - 134.71) / 9.49

z1 = -1.55

z2 = (160 - 134.71) / 9.49

z2 = 2.67

Using a z-table, we find that the probability of getting a z-score less than -1.55 is 0.0606 and the probability of getting a z-score less than 2.67 is 0.9962. So, the probability that the sample mean will be between $120 and $160 is 0.9962 - 0.0606 = 0.9356.

e. To find the symmetrical interval that includes 95% of the sample means, we need to use the formula:

x = μ ± z*SE

where x is the sample mean, μ is the population mean, z is the z-score, and SE is the standard error of the mean.

In this case, μ = $134.71, z = 1.96 (for a 95% confidence interval), and SE = 9.49. So, the symmetrical interval is:

x = 134.71 ± 1.96*9.49

x = 134.71 ± 18.6

x = (116.11, 153.31)

The provide situation can be modeled as a linear equation, y = 50 + 20x, where y is total cost and x is number of person who will attend the party. The slope of line tells me that the additional cost per person attending the party is $20. Thus, write option is option (b).

Emmett wants to through a party at an escape room. There are two charges for

escape room, one is booking fee and other one is additional cost per person attending the party. Let the booking fee and additional cost per person who attended the party of escape room be 'a ' and 'b'. Also, consider total person who will attend the party are equal to 'x'. So, total cost = booking cost + additional cost per person × number of people's who will attend the party. Let total cost of escape room for x people be 'y'. Then,

y = a + bx --(1)

it is act as modeled linear relationship, see above graph, which represents it graphically. In the graph initial total cost is 50, when no additional cost occur, that is booking fee equals to $50 or a = $50. After that, number of people increase total cost also increases. When there are 10 people in party then total cost is $250 and the additional cost = $200 for 10 people. So, additional cost per person

= 200/10 = 20 , i.e., b = $20 and equation(1) is rewrite, y = 50 + 20x.

If we compare it with standard linear equation, y = mx + c

where m --> slope of line

c --> y-intercept

then slope of equation (1) is equals to 'b' and b = 20. In this situation, the slope of line tell me that except the booking fee, the additional cost per person who will attend the party is equals to $20. Hence, the required answer is option(b).

Answer:

5/33

Step-by-step explanation:

5/6 divided by 11/2

Invert the divider

5/6 x 2/ 11

10/66

Reduce to smallest fraction

5/33

Answer:

5/33

Step-by-step explanation:

Apply the fraction rule: a/b ÷ c/d = (a × d) ÷ (b × c) for 5/6 ÷ 11/2

a = 5

b = 6

c = 11

d = 2

(5 × 2) ÷ (6 × 11)

For "(6 × 11)", break 6 down into "2 × 3", so that you can cancel out the common factor, because there is also a 2 in "5 × 2".

= (5 × 2) ÷ (2 × 3 × 11)         -- cancel out the 2's

= 5 ÷ (3 × 11)     *****3 × 11 = 33*****

= 5/33

As a result, the park's estimated area, calculated using a trapezoidal sum with three equally spaced subintervals, is 50 square miles.

A quadrilateral with at least one set of parallel edges is known as a trapezoid. The bases and legs of a trapezoid are referred to by their parallel and non-parallel edges, respectively. The space between the bases of a trapezoid measured perpendicularly is its height. A = (1/2)h(b1 + b2), where A is the area, h is the height, and b1 and b2 are the lengths of the two bases, is the formula for a trapezoid's area.

given

By calculating the function's average at the left and right ends of the subinterval, it is possible to determine the height of each trapezoid.

A1 = (1/2) * (base1 + base2) * height

= (1/2) * (2 + 2) * 9 = 18 is the area of the first trapezoid.

A2 = (1/2) * (base1 + base2) * height

= (1/2) * (2 + 2) * 11 = 22 is the formula for the area of the second trapezoid.

The third trapezoid's area is given by

A3 = (1/2) * (base1 + base2) * (1/2) * (2 + 2). * 10

= 10

The three trapezoids' combined areas make up the entire area under the curve, which roughly corresponds to the size of the park:

A total = A1 + A2 + A3 

= 50

As a result, the park's estimated area, calculated using a trapezoidal sum with three equally spaced subintervals, is 50 square miles.
