Step-by-step explanation:

Two numbers that only have 1 as a common factor are called co-prime numbers.

Example:

Factors of 3 ⇒ 1, 3

Factors of 4 ⇒ 1, 2, 4

These numbers only have 1 as a common factor. So 3 and 4 are co-prime numbers.

Answer: 35 m3

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the base of the pyramid:

Base area = 1/2x base length x height

Base area = 1/2 x 6 x 5 = 15 m2

Volume of a pyramid = 1/3 x base area x height

Replacing with the values given:

V = 1/3 x 15 x 7 = 35 m3

Answer: C. 70 percent

Step-by-step explanation:

Given, Time for the first unit = 50 minutes

Time for the second unit = 35 minutes

The unit improvement factor learning curve = (The time for the second unit) ÷ (time for the first unit) x 100.

So, The unit improvement factor learning curve  = 35÷ 50 × 100 = 70 percent.

Hence, the correct option is "C. 70 percent".

Answer:

The triangle inequality states that the sum of the two shortest side lengths must be greater than the largest side length of the triangle. Basically, we need to find if DE + FE > DF. We know that DE = 1/2 DF and FE = 1/3 DF so the inequality becomes 1/2 DF + 1/3 DF > DF which simplifies to 5/6 DF > DF. Since 5/6th of a number will never be greater than itself, the answer is ED + EF < DF.

Answer:

B. ED + EF < DF

The probability of a student choosing running is 4/63.

Given that,

Total number of students = 63

Number of boys = 38

Number of girls = 63 - 38 = 25

Number of students who chose football = 20

Number of girls who chose football = 19

Number of students who chose tennis = 19

Number of girls who chose running = 5

To find the probability of a student choosing running,

We need to know the total number of students who chose running.

From the given information,

We know that the number of students who did not choose running is:

Number of students who chose football = 20

Number of students who chose tennis = 19

Number of girls who did not choose running = 25 - 5 = 20

Therefore, the total number of students who chose running is:

Total number of students - Number of students who did not choose running

= 63 - (20 + 19 + 20) = 4

So, the probability of a student choosing running is:

Number of students who chose running / Total number of students

= 4 / 63

Therefore, the probability that a student selected at random chose running is 4/63

Answer:

Step-by-step explanation:

Given the width of a rectangle W = x centimeters

If the  length is 10 centimeters longer than the width, then L = (10 + x)cm

Perimeter of the rectangle = 220 cm

To calculate the length, we need to first calculate the value of x. Using he formula for calculating the perimeter of a rectangle to get x;

Perimeter P = 2(L+W)

Substituting the value of the length and the width, we will have;

P = 2(10+x+x)

220 = 2(10+2x)

Dividing both sides by 2;

220/2 = 2(10+2x)/2

110 = 10+2x

2x = 110-10

2x = 100

x = 100/2

x = 50cm

Since the length of the rectangle L = 10+x

The length of the rectangle = 10+50 = 60 cm

Hence, the measure of the length is 60 cm

Answer:

60cms

Answer:

The equation of line g is y = x/3 + 5

Step-by-step explanation:

Given that the line d passes through the points (-3, 1) and (9, 5) we have the equation of line d in slope and intercept form., y = m·x + c found as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where;

(x₁, y₁) = (-3, 1)

(x₂, y₂) = (9, 5)

[tex]Slope, \, m =\dfrac{5-1}{9-(-3)} = \dfrac{4}{12} = \dfrac{1}{3}[/tex]

The line, d, in point-slope form is y - 1 = 1/3(x - (-3))

Which gives;

y - 1 = 1/3·x + 3/3

y = 1/3·x + 1 + 1 = 1/3·x + 2

Given that line g is parallel to line d, we have;

Slope of line g = slope of line d = 1/3

Therefore, the equation of line g passing through point ^6, 7) in point-slope form is y - 7 = 1/3(x - 6) which gives;

y = x/3 - 2 + 7 = x/3 + 5

The equation of line g is y = x/3 + 5

The line f  passing through point (-3, -3) is perpendicular to ling g, therefore, the slope = -1/m = -1(1/3) = -3

The point-slope form of the equation is y -(-3) = -3(x - (-3)) which gives;

y + 3 = -3·x - 9

Therefore, the equation of line f is y = -3·x - 9 - 3 = -3·x - 12

The equation of line f is y = -3·x - 12.

Answer:

(1/2, -3)

Step-by-step explanation:

We have the following equations:

y = 4 * x - 5

y = –3

To solve algebraically, we must replace one equation in another, and we are left with:

-3 = 4 * x - 5

4 * x = 5 - 3

x = 2/4

x = 1/2

Therefore the solution is (1/2, -3)

Now, when we graph both equations, the solution would be the intercept between both graphs, attached corresponding image, the solution would be the same (1/2, -3)

Answer:

26 ≤ x ≤ 39 where x is # of hours

Step-by-step explanation:

If we call the number of hours she works x, Nicole will have made 9.50x after x hours. Therefore, we can write the following compound inequality:

245.60 ≤ 9.50x ≤ 368.40 (Note that we use ≤ instead of <; "at least/most" is denoted by ≤ or ≥)

Dividing the entire inequality by 9.50 (to get rid of the coefficient on x, we get about 26 ≤ x ≤ 39. We round up to the nearest integer because you can't really have, say, 25.69 hours in this context, you would have 26.

35+B+90=180

B=180-125

B=55 degrees

Answer:

first option

Step-by-step explanation:

Given

| x + 4 | = 2

The absolute value function always produces a positive value but the expression inside can be positive or negative, thus

x + 4 = 2 ( subtract 4 from both sides )

x = - 2

OR

- (x + 4) = 2, distribute left side

- x - 4 = 2 ( add 4 to both sides )

- x = 6 ( multiply both sides by - 1 )

x = - 6

Thus solutions are x = - 2, x = - 6

These are represented on the graph by solid blue circles at x = - 2, x = - 6

Answer:

541.4 m²

Step-by-step Explanation:

Step 1: find m < V

V = 180 - (50+63) (sum of the angles in ∆)

V = 67

Step 2: find side length of XW using the law of sines

[tex] \frac{XW}{sin(V)} = \frac{XV}{sin(W)} [/tex]

Where,

V = 67°

W = 63°

XV = 37 m

XW

[tex] \frac{XW}{sin(67)} = \frac{37}{sin(63)} [/tex]

Multiply both sides by sin(67) to solve for XW

[tex] \frac{XW}{sin(67)}*sin(67) = \frac{37}{sin(63)}*sin(67) [/tex]

[tex] XW = \frac{37*sin(67)}{sin(63)} [/tex]

[tex] XW = 38.2 m [/tex] (to nearest tenth)

Step 3: find the area using the formula, ½*XW*XV*sin(X)

area = ½*38.2*37*sin(50)

Area = 541.4 m² (rounded to the nearest tenth.

           The distance is:   [tex]\sqrt3\ cm\approx1,73\,cm[/tex]

Step-by-step explanation:

The distance of point E to the PQR plane it is the hight (vertical) of piramid PRQE

If point P is located in the middle of line EH, point Q is in the middle of line EF, and point R is in the middle of line AE than:

EP = EQ = ER = 0.5EF = 3 cm  and  m∠REQ = m∠QEP = m∠REP = 90° so triangles RQE, QPE and PRE are congruent.

RQ = QP = PR so triangle PQR is equilateral and from Pythagorean theorem (for ΔRQE):

[tex]RQ^2=ER^2+EQ^2=3^2+3^2=2\cdot3^2\ \ \implies\ \ RQ=3\sqrt2[/tex]

Then: [tex]RN=\dfrac{RQ\,\sqrt3}2[/tex]

and:  [tex]RK=\dfrac23RN=\dfrac{RQ\,\sqrt3}3=\dfrac{3\sqrt2\cdot\,\sqrt3}3=\sqrt6[/tex]

Therefore from Pythagorean theorem (for ΔERK):

[tex]EK^2+RK^2=ER^2\\\\EK^2=ER^2-RK^2\\\\EK^2=3^2-(\sqrt6)^2\\\\EK^2=9-6=3\\\\EK=\sqrt3\ cm\approx1,73\,cm[/tex]

Answer:

a positive 1; negative 3 or 1

Step-by-step explanation:

To determine the number of positive roots, we have to determine the number of sign changes for f(x) = x⁴ + 2x³ - 3x² - 8x - 4.

The coefficients in f(x) are +1, +2, -3, -8, -4.

Since there is only one sign change from +2 to -3, we have 1 positive root.

To determine the number of negative roots, we have to determine the number of sign changes for f(-x) = (-x)⁴ + 2(-x)³ - 3(-x)² - 8(-x) - 4 = x⁴ - 2x³ - 3x² + 8x - 4

The coefficients in f(-x) are +1, -2, -3, +8, -4.

Since there is three sign change from +1 to -2, from -3 to +8, and from +8 to -4. So,we have 3 or 1 negative root, since the number of negative roots is equal to the number of sign changes or an even number less than the number of sign changes. So, 3 -2 = 1

So, the number roots are of positive 1; negative 3 or 1
