8*3 = 24

8*7 = 56

Therefore the answer is 3/7

Hey there!

24/56

= 24 ÷ 8 / 56 ÷ 8

= 3/7

Step-by-step explanation:

the second equation gives us right away

y = 4 - 3x

we can use that now in the 3rd equation :

-2(4 - 3x) + 2z = 4

-8 + 6x + 2z = 4

6x + 2z = 12

3x + z = 6

z = 6 - 3x

now we use both in the 1st equation :

-2x + 3(4 - 3x) - (6 - 3x) = -2

-2x + 12 - 9x - 6 + 3x = -2

-8x + 6 = -2

-8x = -8

x = 1

y = 4 - 3x = 4 - 3×1 = 4 - 3 = 1

z = 6 - 3x = 6 - 3×1 = 6 - 3 = 3

so,

(1, 1, 3)

Answer:

2x+4x+3x+12=0

The equation of line passing through (1, -17) with slope 4 will be y = 4x - 21 .

What is the slope intercept form of a line ?

The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

The equation of a line which is passing through point (1 , -17) with slope m = 4 can be found by using the slope intercept form which is given by :

y = mx + c

Here ; m is the slope and c is the y - intercept of the line.

So ;

The point given is (x , y) = (1, -17) and slope m = 4. Let's use these values to find out the equation of the line. But before that let's find out the value of y-intercept (c).

-17 = (4 × 1) + c

c = - 17 - 4

c = -21

Hence , the equation of line passing through (1, -17) will be :

y = 4 ×  x + (-21)

or

y = 4x - 21

Therefore , the equation of line passing through (1, -17) with slope 4 will be y = 4x - 21 .

The rate of change of the surface area of the cylinder is approximately to 18.473 square meters per second.

In this question we find a formula for the surface area of a cone, of which we must estimate its rate of change by applying derivative rules and the concept of rate of change. The rate of change is the first derivative of the equation:

ds / dt = 2π · r · (dr / dt) + π · √(r² + h²) · (dr / dt) + π · r · [0.5 / √(r² + h²)] · [2 · r · (dr / dt) + 2 · h · (dh / dt)]

If we know that r = 3 m, h = 4 m, dr / dt = 0.5 m / s and dh / dt = 0.2 m / s, then the rate of change of the surface area of the cone is:

ds / dt = 2π · (3 m) · (0.5 m / s) + π · √[(3 m)² + (4 m)²] · (0.5 m / s) + π · (3 m) · [0.5 / √[(3 m)² + (4 m)²] · [2 · (3 m) · (0.5 m / s) + 2 · (4 m) · (0.2 m / s)]

ds / dt ≈ 18.473 m² /s

We take the value 2 for which y(2)=4 and [tex]y^{2}[/tex]=2 and see that y(x)=[tex]x^{2}[/tex] is a function and [tex]y^{2}[/tex]=x is a relation.

Domain is the set of values that a variable can take in an algebraic expression.For the equation y(x)=[tex]x^{2}[/tex], x can take any value from negative infinity to positive infinity so we can say that the domain for x is (-∞,∞). For the equation [tex]y^{2}[/tex]=x, x can take any value greater than or equal to zero. Since x=[tex]y^{2}[/tex] we can't take a negative value for x because squared numbers are always positive, so the domain of x will be [0,∞). The common domain for both the equations is [0,∞). Let us choose a value from this common domain,let's say 2. Then for

y(x)=[tex]x^{2}[/tex]⇒y(2)=4 ...(i)

[tex]y^{2} =x[/tex]=2 then y=±[tex]\sqrt{2}[/tex]...(ii)

A function always has an output variable and one or more input variables.For first equation, y is the output variable and x is the input variable. A relation states that two expressions are equal and one is not dependant on another. For equation (i) y is dependant on x but in equation (ii) both the variables are independant.

Thus we can conclude that y(x)=[tex]x^{2}[/tex] is a function and [tex]y^{2}[/tex]=x is a realtion.

Answer:

x =52

Step-by-step explanation:

The angles shown are same side interior angles, and when the lines are parallel, same side interior angles add to 180 degrees

< 1 + <2 = 180

x+23    + x+53   = 180

Combine like terms

2x+ 76 = 180

Subtract 76 from each side

2x+76-76 = 180 -76

2x = 104

Divide by 2

2x/2 = 104/2

x =52

Answer:

x = 52

Step-by-step explanation:

Angle 1 and angle 2 are on the same side, and on the inside of the interior. This means that when added together they = 180

We can set up an equation

x+23+x+53 = 180

Simplify: 2x + 76 = 180

Subtract 76 from both sides

2x = 104

Now divide by 2

x = 52

In dataset 60 is the data is spread more tightly around the mean than in other datasets. Accordingly, it would have a smaller standard deviation.

n dataset C, the data is spread more tightly around the mean than in other datasets. Accordingly, it would have a smaller standard deviation

Standard deviation is 60

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. The curve at the top is more dispersed and has a greater standard deviation than the curve at the bottom, which is more concentrated around the mean and has a lower standard deviation.

Using the ratio given in the question,

The relation between the quantities of two or more objects—referred to as a ratio—indicates how much of one object is contained in the other. The ratio formula can be used to represent a ratio as a fraction. The ratio formula is given as, for any two quantities, let's assume a and b.

a:b = a/b

Given that James, Fay and Sal share 160 apples.

Total number of apples =  160

Hence, apples received by James = 1/4(160)

= 40 apples

Remaining apples = 160 - 40 = 120 apples

It is also given that the remainder is shared by Fay and Sal in the ratio 3:2.

Hence, the total share will be 3+2=5

So, we can write that Fay's share will be 3/5 of total apples and Sal's share will be 2/5 of the total apples.

Fay's share = 3/5(120)

=3(24)

=72 apples

Sal's share = 2/5(120)

=2(24)

=48 apples

Therefore, the number of apples with Fay is 72.

Define the variables:

If the bacteria grows on food by doubling every hour then the growth rate b = 2.

If the bacteria initially covers 10% of the food then y = 10% when x = 0.

The probability that they are both left-handed is 0.01

Probability is the number of ways of achieving success.

the total number of possible outcomes.

Probability takes values between 0 (no chance) and 1 (certain) inclusive.

Complement Rule (probability that an event doesn't occur): P(A') = 1 - P(A) .

Addition rule: P(A ∪ B) = P(A) + P(B) – P(A ∩ B) .

Multiplication rule: P(A ∩ B) = P(A) × P(B) for independent events. P(A ∩ B)

For both, the persons selected at random are left-handed

10 % out of 100 % are left-handed.

Hence the probability that the person is left-handed

P(L) = 10 /100 = 1 / 10 = 0.1

where P(L) is the probability that the person is left-handed.

Therefore both the persons selected are left-handed

The ending number is related to the starting number by n + 9.

To start with this magic number puzzle, let us take a positive number and a negative number. After that we have to perform some simple mathematical operations,

Taking positive number as 10 and negative number as -8.

Now, performing the mathematical operations as described in the next steps.

First starting with positive number which is 10.

Step-1. Add 10

So, 10+10 = 20

Step-2. Multiply by 2

So, 20×2 = 40

Step-3. Subtract 2,

So, 40 - 2 = 38

Step-4. Divide by 2,

So, 38/2= 19

Number chosen in the starting was 10 and at the end it became 19. The number 9 got added to 10.

Now, performing the steps on our negative number which is -8,

Step-1. Add 10

So, 10-8=2

Step-2. Multiply by 2

So, 2×2 = 4

Step-3. Subtract 2

So, 4-2 = 2

Step-4. Divide by 2

So, 2/2 = 1.

Number chosen in the starting was -8 and after performing the steps it became 1.

Now, for any number 'n',

Step-1. Adding 10

So, n+10

Step-2. Multiply by 2

So, 2(n-10) = 2n+20

Step-3. Subtract 2

So, 2n+20-2 = 2n+18

Step-4. Divide by 2.

So, (2n+18)/2 = n+9

The number taken in the starting was n and now it became n+9.

So the ending number becomes 9 times more in the end then the starting number.

Angles which are on the same line are supplementary angles. The sum of supplementary angles are always equals to 180 degree.

Some common terms related to angles :

In the given question:

Let measure of ∠E = x

and, measure of ∠F = y

as ∠E and ∠F are supplementary angles therefore their sum is 180

i.e. m∠E + m∠F = 180

=> x + y =180

also, m∠E is 54 more than m∠F

=> y+54 + y = 180

=> 2y + 54 = 180

=> y = 180-54 / 2 = 63

and , x = y + 54 = 63 + 54 = 117

Hence, ∠E = 117 degree and ∠F = 63 degree
