Directions: Solve for the variable in the following equations.

Yakvenalex [24]

Answer:

Step-by-step explanation:

a. 1/2x = 10 x = 20

b. 1/4s = 8 s = 32

c. 1/3t = 6 t = 18

d. 1/5 y = 20 y = 100

4. Division

a. 4x = 32 x = 8

b. 13x = 39 x = 3

c. 5x = 25 x = 5

d. 10x = 100 x = 10

5. Mixed Practice

a. x + 4 = 7 x = 3

b. 33 - y = 44 y = -11

c. s + 18 = 26 s = 8

d. m - 40 = 20 m = 60

e. z + 100 = 100 z = 0

f. x + 22 = 23 x = 1

g. s - 4 = 96 s = 100

h. 1/4x = 4 x = 16

i. 24x = 3 x = 1/8

j. 1/5x = 50 x = 250

k. 1/3y = 33 x = 99

l. t + 12 = 16 t = 4

m. t - 12 = 16 t = 28

n. 1/2q = 8 q = 16

o. 12t = 24 t = 2

A cone has a volume of 37.68cm3. If the height of the cone is 9cm what is the radius of the cone's

JulijaS [17]

Answer:

$2cm$

Step-by-step explanation:

Volume of a cone= $\pi r^2\frac{h}{3}$

Substitute: $37.68cm^3=\pi r^2(\frac{9}{3})$

$37.68cm^3=\pi r^2(3)$

$37.68cm^3=\pi r^2(3)$ Divide by 3

$12.56cm=\pi r^2$ Divide by pi

$4cm=r^2$

$r=\sqrt{4}$

$r=2$

The authors of the paper "Statistical Methods for Assessing Agreement Between Two Methods of Clinical Measurement"† compared two

lesantik [10]

Answer:

Step-by-step explanation:

Given data;

n = 17

$\sum x =7692$

$\sum x^2=3685124$

$\sum y =7656\\\\ \sum xy=3662682$

Slope:

$\hat B_1=\frac{n \sum xy - \sum x \sum y}{n \sum x^2 - ( \sum x)^2} \\\\=0.96994$

≅ 0.970

y - intercept :

$\hat B_0 = \frac{\sum y}{n} - \hat B\frac{\sum x}{n} \\\\=11.48178$

≅ 11.482

Equation :

$\hat y = 11.482+0.970x$

Predicted wright meter reading

$\hat y = 11.48178+0.96994(563)\\\\=557.558$

c)Predicted wright meter reading

$\hat y = 11.48178+0.96994(342)\\\\= 343.201$

What is the equation of a line that contains point (4, –3) and is PARALLEL to –4x + y = 7?

Otrada [13]

Answer:

(4,3),y=(7)/(4)x+1

Step-by-step explanation:

To find an equation that is parallel to y = 7 4 x + 1 y=74x+1, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula. ( 4 , 3 ) (4,3) m = 7 4

Using the point-slope form y − y 1 = m ( x − x 1 ) y-y1=m(x-x1), plug in m = 7 4 m=74, x 1 = 4 x1=4, and y 1 = 3 y1=3. y − ( 3 ) = ( 7 4 ) ( x − ( 4 ) )

Solving for y:

Multiply − 1 -1 by 3 3. y − 3 = ( 7 4 ) ( x − ( 4 ) ) y-3=(74)(x-(4)) Simplify ( 7 4 ) ( x − ( 4 ) ) (74)(x-(4)).

y − 3 = 7 x 4 − 7

y = 7 x 4 − 4 y=7x4-4 Reorder terms. y = 7 4 x − 4
