Problem 12

Answer:

Fred paid $258 and Shannon paid $142

Step-by-step explanation:

Hope this helps!

Answer:

i belive that the one who payed more paid 258 dollars

Step-by-step explanation:

400/2=200

200+58+258

the guy who paid less paid 142 dollars because 400-258=142

4. Not enough info, the shape is cut off. Are there 4 sides or 5? If there's a 5th side, is it slanted or parallel to the one labeled 10 ft?

5. The circle has a radius of 7 m, so its area is

π (7 m)² = 49π m²

Subtract from this the area of the white triangle. It has a base length equal to the diameter (i.e. twice the radius) of the circle, and a height equal to the radius, so its area is

1/2 (14 m) (7 m) = 49 m²

So the area of the shaded region is (49π - 49) m², or 49 (π - 1) m².

6. The rectangle has length 14 yd and height equal to the diameter of the circular cutout, 10 yd, so its area is

(14 yd) (10 yd) = 140 yd²

The circular cutout is a semicircle with radius 5 yd, so its area is

1/2 π (5 yd)² = 25π/2 yd²

Then the area of the shaded region is (140 - 25π/2) yd², or 1/2 (280 - 25π) yd².

7. The circle has radius 13 in, so its area is

π (13 in)² = 169π in²

The triangle has height 23 in and length 12 in, so its area is

1/2 (23 in) (12 in) = 138 in²

Then the area of the shaded region is (169π - 138) in².

8. The shaded region is a rectangle with a smaller rectangular cutout. The larger rectangle has height 19 cm and length 18 cm + 16 cm = 34 cm, so its area is

(19 cm) (34 cm) = 646 cm²

The smaller rectangular cutout has length 16 cm and height 19 cm - 16 cm = 3 cm, so its area is

(16 cm) (3 cm) = 48 cm²

Then the area of the shaded region is 646 cm² - 48 cm² = 598 cm².

9. The semicircular piece has radius 3 m, so its area is

1/2 π (3 m)² = 9π/2 m²

The triangle has height equal to the semicircle's diameter, 6 m, and length 9 m, so its area is

1/2 (6 m) (9 m) = 27 m²

Then the area of the shaded region is (9π/2 + 27) m², or 1/2 (9π + 54) m².

Answer: 1) m=2, 2) m=-2/3, 3) m=-2/5 4) m=-1/2 5) m=4 6) m=1

Step-by-step explanation:

2, 3, & 4 are all declining so they are going to be negative and 1, 5, & 6 are all inclining so they’re positive. When you put the amount you go up vertically from point to point over the amount you travel horizontally between each point you should get the slope for each graph.

Answer: 900

Step-by-step explanation:

Hello!

First what you want to do is divide 600 by 40 to get 15.

Since there are 60 minutes in one hour you will multiply 15 * 60

to get a total of 900 students.

Hope this helps!

Answer:

3 is your answer.

Step-by-step explanation:

Divide 160 by 5 and you get 32. Multiply it by 3 to get to 96 so it ends up as 3.

Answer:

x = 3

Step-by-step explanation:

To find this, let's use a ratio of gallons of gas to miles the car is able to travel.

160 miles / 5 gallons is equal to 96 miles / x gallons, or 160/5 = 96/x.

Cross multiply to get 160x = (5)(96)

Multiply the 96 by the 5 to get 160x = 480

Divide both sides by 160 to get x = 3.

Answer: 414 cars

Step-by-step explanation:

We need to add 328 and 86 together:

Answer:

Matt has 414 cars in his car collection now.

Step-by-step explanation:

Answer: A false, B true, C true

Step-by-step explanation:

A) intercept with y axis

That means x=0

y= 3*0-2

y= -2 So A is false

B) intercept with x axis

That means y=0

0= 3x-2

2=3x

2/3= x B is true

C) The form of linear function is

f(x)= mx +n, where m is the slope

In this case m= 3 so C is true

1. The y - intercept is 2. ⇒ False

2. The x - intercept is 2/3 ⇒ True.

3. The slope is 3. ⇒ True.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The function is,

f (x) = 3x - 2

Now,

1. To find the y - intercept we substitute x = 0 in the function.

Hence, The y - intercept is,

f (x) = 0 - 2

f (x) = - 2

Hence, The statement y - intercept is 2 is False.

2. To find the x - intercept we substitute f(x) = 0 in the function.

Hence, The y - intercept is,

f (x) = 3x - 2

0 = 3x - 2

3x = 2

x = 2/3.

Hence, The statement x - intercept is 2/3 is True.

3. We know that;

The slope intercept form of the line is,

y = mx + b

Where, m is slope of the line.

And, b is y - intercept.

So, By comparing with the function f (x) = 3x - 2 , we get;

Slope (m) = 3

Hence, The slope is 3 is True.

Step-by-step explanation:

Answer:

-11.8, -30.8, and range is {7.2, 1.12, -4.2, -34.6}

Step-by-step explanation:

t(x)= -3.8x-4.2

Evaluate the function for

x=2 is t(x=2)=-3.8*2-4.2= -11.8

x=7 is t(x=7)=-3.8*7-4.2=-30.8

domain are the values of x and are {-3, -1.4, 0, 8}

the range are the values of y or values of t(x)

t(x=-3)= 11.4 -4.2 =7.2

t(x=-1.4)= 5.32 -4.2 =1.12

t(x=0)= -4.2

t(x=8)= -30.4-4.2= -34.6

so the range is {7.2, 1.12, -4.2, -34.6}

For instance, if the point (1, 3) is on the graph of the function, then the point (3, 1) is on the graph of the inverse. That is, if you start with x = 1, you will go to y = 3; then you plug this into the inverse, and you'll go right back to x = 1, where you started from.
