The total cost would be $1248.

To find the total cost, we need to first find the area of the parallelogram. To find the area, we need to multiply the base and height.

Then, we need to multiply the total area by the cost of $2.60.

32 x 15 x 2.6 = 1248

**Answer:**

$1248.

**Step-by-step explanation:**

area = base x height.

then

area x cost

b h c

32 x 15 x 2.6 = 1248

Question

Lyla took a total of 16 quizzes over the course of 4 weeks. After attending 8 weeks of school this quarter, how many quizzes will Lyla have taken in total? Assume the relationship is directly proportional.

Solution 1

32 quizzes. If you make a proportion of quiz/weeks it would be 16/4 = x/8. Multiply by 2.

Question

A rectangle has a perimeter of 54 meters and a height of 14 meters. What is the length of the base? Please help!!

Solution 1

13 because if the height is 14 you would subtract 28 because there’s two sides. Then you would get 26, divide that by 2 and get 13 for the base. Idk if it makes sense

Question

A new patio will be an irregular hexagon. The patio will have two long parallel sides and an area of 360 square feet. The area of a geometrically similar patio is 250 square feet, and it’s long parallel sides are 12.5 feet apart. What is the corresponding distance on the new patio

Solution 1

The length of the new patio will be evaluated as follows:

The area scale factor=(area of new patio)/(area of original patio)

=360/250

=36/25

but

Linear scale factor=√(area scale factor)

Linear scale factor=√(36/25)=6/5

thus the length of the patio will be:

length=(linear scale factor)*(length of the original patio)

=6/5×12.5=15 ft

The area scale factor=(area of new patio)/(area of original patio)

=360/250

=36/25

but

Linear scale factor=√(area scale factor)

Linear scale factor=√(36/25)=6/5

thus the length of the patio will be:

length=(linear scale factor)*(length of the original patio)

=6/5×12.5=15 ft

Question

Mitch does not know the correct answer to two multiple choice questions. The choices are A,B,C, and D. If Mitch just guesses, what is the probability that Mitch will guess both answers correctly?

Solution 1

Both chances to success are 1/4. If you want the first AND the second to be successful, you have to multiply the chances, so the answer is

1/4 * 1/4 = 1/16

1/4 * 1/4 = 1/16

Question

David and Brad are competing in a 20-mile bicycle race. David rides 6.2 miles in 1/4 hour. Brad rides 11.9 miles in 1/2 hour. If both riders continue at the same average speed, who will finish first? Explain how you know.

Solution 1

First, you calculate David's and Brad's unit rate.

David:

6.2 mi./1/4 hr. = 6.2 m./15 minutes

In an hour, there's 60 minutes. 60 divided by 4 is 15. So 1/4 of an hour is 15 minutes.

Brad:

11.9 mi./1/2 hr. = 11.9 mi./30 minutes

Once again, there's 60 minutes in an hour, so 1/2 of an hour is 30 minutes.

Okay, observing both of the unit rates, David's speed is just about half of Brad's speed. As a result, you multiply David's unit rate twice to get the same amount of time as Brad. It's easier to solve if you think about fractions since unit rates and fractions are just about the same. Now, multiply both the numerator and denominator by 2:

6.2 x 2 = 12.4, and 15 x 2 = 30

Now that you've multiplied them by two, David and Brad are now continuing at the same average speed.

David: 12.4 mi./30 min.

Brad: 11.9 mi./30 min.

David will finish the bicycle race first since he's gone farther than Brad.

I really hope I helped! :) There are so many other ways to solve this, but here's one way that I know best. If I didn't help, I'm sorry. I tried. :(

David:

6.2 mi./1/4 hr. = 6.2 m./15 minutes

In an hour, there's 60 minutes. 60 divided by 4 is 15. So 1/4 of an hour is 15 minutes.

Brad:

11.9 mi./1/2 hr. = 11.9 mi./30 minutes

Once again, there's 60 minutes in an hour, so 1/2 of an hour is 30 minutes.

Okay, observing both of the unit rates, David's speed is just about half of Brad's speed. As a result, you multiply David's unit rate twice to get the same amount of time as Brad. It's easier to solve if you think about fractions since unit rates and fractions are just about the same. Now, multiply both the numerator and denominator by 2:

6.2 x 2 = 12.4, and 15 x 2 = 30

Now that you've multiplied them by two, David and Brad are now continuing at the same average speed.

David: 12.4 mi./30 min.

Brad: 11.9 mi./30 min.

David will finish the bicycle race first since he's gone farther than Brad.

Question

Jika f(x-1)=2x+5 dan g1(x-2)=4x+2 maka (g•f)1(0)

Solution 1

G (x) = x + 1 (fog) (x) = x 2 + 3x + 1 ⇒ (fog) (x) = x 2 + 3x + 1 ⇒ f (g (x)) = x 2 + 3x + 1 ⇒ f (x + 1) = x 2 + 3x + 1 Eg x + 1 = p, then x = p - 1. ⇒ f (p) = (p - 1) 2 + 3 ( p - 1) + 1 ⇒ f (p) = p 2 - 2p + 1 + 3p - 3 + 1 ⇒ f (p) = p 2 + p - 1 So f (x) = x 2 + x - 1 - ->

ANSWER IS : x 2 + x - 1

ANSWER IS : x 2 + x - 1

Question

Solution 1

274.3 centimeters is closest to the equivalent

Question

explain why in any triangle the difference of the lengths of any two sides cannot be greater that the length of the third side.

Solution 1

Becuase then the 3 lines woul dnot connect

if you draw any 1 line of legnth w

then lets say you draw a line of legnth w/2 and (2/w)-1

then you would have 2 lines that are too short to connect

try it yourself

basically lets say we have sides legnth 3,6,10

10-6 is more than 3

if you draw a line that is 10 legnth and try to draw 1 line at each end, one which is 3 legnth and the other which is 6 legnth, you cannnot connect the 3 and 6 line becuase they are 1 unit too short, if they were 1 unit longer, then the triangle would be a line

if you draw any 1 line of legnth w

then lets say you draw a line of legnth w/2 and (2/w)-1

then you would have 2 lines that are too short to connect

try it yourself

basically lets say we have sides legnth 3,6,10

10-6 is more than 3

if you draw a line that is 10 legnth and try to draw 1 line at each end, one which is 3 legnth and the other which is 6 legnth, you cannnot connect the 3 and 6 line becuase they are 1 unit too short, if they were 1 unit longer, then the triangle would be a line

Question

Two cyclists leave town at the same time on the same road going in the same direction. Cyclist a is going 6 miles per hour faster than cyclist b. After 8 hours, cyclist a has traveled three times the distance as cyclist b. Use the equation 24x= 8(x+6) to find how fast cyclist b was traveling.

Solution 1

**Answer:**

**3 mph**

**Step-by-step explanation:**

Two cyclists leave town at the same time on the same road going in the same direction.

Cyclist A is going 6 mph faster than cyclist B

Let speed of cyclist B be x mph

Speed of cyclist A be (x+6) mph

Both cyclist leave town at the same time and traveled 8 hours.

- Distance covered by cyclist A in 8 hours= 8(x+6)

- Distance covered by cyclist B in 8 hours= 8x

After 8 hours cyclist A has traveled 3 times the distance as cyclist B

Therefore, 8(x+6) = 3(8x)

8x + 48 = 24x

24x - 8x = 48

16x = 48

x = 3 mph

**Hence, The speed of cyclist B was 3 mph**

Solution 2

24x=8x+48

16x=48

/16 /16

**x=3**

16x=48

/16 /16
