Answer 1

Answer:

The correct answer is E, 551.6 square feet.

Step-by-step explanation:

I think we can assume that the two ends are perfect semi-circles, although that's not clearly specified.

In that case, the total area we have is that of a 15x25 foot rectangle, plus a circle with a diameter of 15ft.

So lets work that out.  The rectangle is easy, as the area is just width times height. 15 ft * 25 ft is 375 ft²

The area of a circle is defined as πr².  We're given the diameter, which is twice the radius, so the collective area of the two ends would be π × 7.5² which equals π × 56.25, or approximately 176.7 square feet.

Now we just need to add those together:

375 + 176.7 = 551.7

The difference in answer will be due to rounding, so we know that the correct answer is E, despite their answer being rounded incorrectly.

(2/5)^8 x (2/5)^-2 / (5/2)^-7

Answers

Answer:

The required answer is ⅖¹³.

Step-by-step explanation:

Given terms to us is :-

[tex]=\bf \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{5}{2}^{-7}[/tex]

We can see here that two terms have same base that is ⅖ . And the other is 5/2. So for simplifing the expression we will use some laws of exponents , which are :-

a ^m + aⁿ = a^{m + n }a -ⁿ = ( 1/a )ⁿ

Using these we have ,

[tex]\bf = \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{5}{2}^{-7} \\\\\bf= \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{2}{5}^7 \\\\\bf= \bigg(\dfrac{2}{5}\bigg)^{(8+7-2)}\\\\\boxed{\red{\bf= \dfrac{2}{5}^{13}}}[/tex]

2/5 ^13 is your answer!!!

Answer:

7.19

Step-by-step explanation:

Answer

$7.20 if you round up. Not rounded is $7.198 or just $7.19

Step-by-step explanation

First, get original price which is $9 rounded.

Then, multiple by percent off which would be .20 or .2. Don't get this confused with 2% off which is .02.

After multiplying, you should get the answer of $1.80, this is 20% of $9.00. So if the product was 20% off, you would subtract. This gives you the final answer of $7.20

Find the missing right triangle side lengths in the models of the Pythagorean Theorem below

Answers

Answer: 24, 10, 26 and 4.6, 5, 6.7

Step-by-step explanation: for the first triangle the square with the area 576 has side lengths of 24 because 24 is the square root of 576, the square with the area 676 has a side length of 26 because 26 is the square root of 576, and we already know the side lengths of the third triangle are 10 for the second triange we know the side length of the square with the area 21 is about 4.6 because √21 ≈ 4.6 and the square with the area 25 the side length is 5 because √25 = 5 and the last square the side length is 6.7 because √46 ≈ 6.7
