Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. After running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. He converts the average rate to feet per second as shown below: He concludes that she is not running fast enough to exceed her fastest time. What errors did the coach make? Check all that apply. He used an incorrect time ratio converting hours to minutes. His units do not cancel. He used an incorrect distance ratio converting miles to feet. He incorrectly concluded that she is not running fast enough. He cannot determine her average rate in miles per hour after only 15 minutes.

Answers

Answer:

a.  He used an incorrect time ratio converting hours to minutes.

d. He incorrectly concluded that she is not running fast enough.

Step-by-step explanation:

Looking at the Coach's method of conversion when converting time, he assumed that an hour had 15 minutes instead of 60 minutes. He therefore did not use the correct time ratio to convert hours to minutes.

The coach's calculations yielded an answer of 34 ft/s. This is way faster than 8.8 ft/ s so his deduction that she was not running fast enough to beat her fastest time is incorrect because at that inhumane speed, she did.

Answer: A.)He used an incorrect time ratio converting hours to minutes.

D.)He incorrectly concluded that she is not running fast enough.

Jill orders t-shirts on Amazon. Each shirt costs $15.00 including tax. A one-time shipping fee of $3.25 is added to the cost of the order. The total cost of Jill's order is $78.25. How many t-shirts did Jill order? *

Answers

Answer:

5 shirts

Step-by-step explanation:

Step one:

given data

Each shirt costs $15.00 including tax.

A one-time shipping fee of $3.25

The total cost of Jill's order is $78.25

Step two:

let the number of shirts be x

so

y=15x+3.25

for y= $78.25, let us find x

78.25=15x+3..25

collect like terms

75= 15x

divide both sides by 15

x=75/15

x=5

Answer:

-2 tiles

Step-by-step explanation:

In each figure, 5 tiles are added.

Subtract 5 from how many tiles are in Figure 2 (8 tiles) & you get 3.

3 is how many tiles are in Figure 1, meaning you need to subtract 5 again to see how many are in Figure 0! 3-5 = -2.

In triangle QRS the measurement of an angle RSQ is 29.1 and the measure of angle QRS is 70 degrees what is the measurement of sqr

Answers

Answer: The measure of ∠SQR= 80.9°

Step-by-step explanation:

Given: In triangle QRS,

∠ RSQ = 29.1° and ∠QRS=70°

To find: ∠SQR

Angles sum property of triangle = Sum of all the angles in a triangle is 180°.

For Δ QRS,

∠SQR + ∠ RSQ +∠QRS = 180°

⇒ ∠SQR + 29.1° + 70° = 180°

⇒ ∠SQR + 99.1° = 180°

⇒ ∠SQR= 180°-99.1

⇒ ∠SQR= 80.9°

Hence, the measure of ∠SQR= 80.9°

What is the solution to this system of equations? 5x + 2y= 29
x + 4y = 13

A x = 5, y = 3
B. x=2, y=5
C. X= 5, y = 2
D. x= 3, y = 2​

Answers

Answer:

C

Step-by-step explanation:

Given the 2 equations

5x + 2y = 29 → (1)

x + 4y = 13 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate the y- term

- 10x - 4y = - 58 → (3)

Add (2) and (3) term by term to eliminate y

- 9x + 0 = - 45

- 9x = - 45 ( divide both sides by - 9 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (2)

5 + 4y = 13 ( subtract 5 from both sides )

4y = 8 ( divide both sides by 4 )

y = 2

Solution is x = 5, y = 2 → C

Answer:

c) x = 5, y = 2

Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.

Answers

Answer:

41.25 ft^2

Step-by-step explanation:

Literally all you need to do is Pythagorean Theroem.

a = ?

b = 11ft

c = 8ft

a^2 + b^2 = c^2

a^2 + 11^2 = 8^2

a^2 + 121 = 64

64 - 121 = a^2

a = 7.5

Then area of a triangle formula is (bh)/2

(11 x 7.5)/2 = 41.25
