Evaluate the expression for the given value of the variable 1. 8q + 6; q = 2 2. 9 + 4g; g = -3 3. 7x - 7 ; x = 4 4. 10 - 3.2n; n

BlackZzzverrR [31]

Evaluate the expression for the given value of the variable

1. 8q + 6; q = 2

Plug in 2 for q in the given expression

8(2) + 6= 22

2. 9 + 4g; g = -3

9 + 4(-3) = 9 - 12 = -3

3. 7x - 7 ; x = 4

7(4) - 7 = 28 -7 = 21

4. 10 - 3.2n; n = 2

10 - 3.2(2) = 10 - 6.4 = 3.6

5. 12p + 4; p = 1.5

12(1.5) + 4= 18 + 4 = 22

6. 5w + 10 = 40

Subtract both sides by 10

5w = 30, now divide both sides by 5

w = 6

7. 4y - 12 = 60

Add both sides by 12

4y = 72

Now divide both sides by 4

y = 18

8. 10k + 5 = 65

Subtract both sides by 5

10k = 60, now divide both sides by 10

k = 6

9. 2b - 15 = 33

Add both sides by 15

2b = 48

Now divide both sides by 2

b = 24

10. 3d + 18 = 21

Subtract both sides by 18

3d = 3, now divide both sides by 3

d= 1

Helppp pleaseeeee The object below is made of solid plastic. It is a cylinder with an indentation at the top in the shape of a c

Jobisdone [24]

Answer:

Total volume = (145/3)π in³

Step-by-step explanation:

First find the volume of the entire cylinder. The correct formula to use here is:

V = πr²h, where r is the radius and h is the height. Here, with the radius being 5/2 inches and the height being 8 inches, the cylinder volume is

V = π(2.5 in)²(8 in) = 50π in³

Next find the volume of the conical shape: V = (1/3)π(2.5 in)²(0.8 in)

The desired volume is equal to the volume of the entire cylinder LESS the volume of the cone:

π(2.5 in)²(8 in) = 50π in³ LESS (1/3)π(2.5 in)²(0.8 in), which simplifies as follows:

Total volume =

50 π in³ - (1/3)π(2.5 in)²(0.8 in), or

(2.5 in)²π[8 in - 0.8/3 in] = π(6.25 in²)(8 in - 8/30 in) = π( 6.25 in²)(116/15 in), or

Total volume = (145/3)π in³

In the equation y= -2x -3 over 5, identify the slope, the y-intercept, and whether the line is rising, falling, horizontal, or v

Hoochie [10]

Answer:

Slope = -2

y-intercept = -3/5

Falling

Step-by-step explanation:

$y= -2x - \frac{3}{5} \\ y = mx + b$

m = Slope = -2

y-intercept = b =

$- \frac{3}{5}$

The slope of the equation has a negative number so the graph is falling
