Answer:

Answer A (or C. Both were very close)

Step-by-step explanation:

I don't know what "please only answer if you know not to ask a question" means.

Since ∠ADB is 90° and ∠BAD is 36°, then ∠ABD is 180-90-36 or 54°.

You could just try using the Pythagorean Theorem for all the answer choices.

(a²+b²=c² where a and b are the legs and c is the hypotenuse)

A.

11²+8²=c²

121+64=c²

c=\sqrt{185}

c ≈ 13.60

B.

I don't need to prove this because the shorter legs' sum is greater than the hypotenuse and will not make a triangle.

C.

15.1²+11²=c²

288.01+121=c²

c=\sqrt{349.01}

c ≈ 18.68 ≈ 18.7

D.

I don't need to prove this because the shorter legs' sum is greater than the hypotenuse and will not make a triangle.

I think answer A is the best since it rounds closer to the answer in the row. It was pretty close between C and A so you can decide if you'd like but I suggest A because it's a closer rounding.

The chart below shows conversion between gallons and fluid ounces.
Ainat [17]
<h3>Answer:  768</h3>

======================================================

Explanation:

To go from gallons to fluid ounces (abbreviation fl oz), we multiply by 128

For example, 2 gallons becomes 2*128 = 256 fl oz as shown in the table.

Another example: 3 gallons = 3*128 = 384 fl oz.

Therefore, 6 gallons would be 6*128 = <u>768</u> fl oz.

To go in reverse, from fl oz to gallons, we divide by 128.

1. h(2) + g(2) *<br> h(t) = 3-5<br> g(t) = 2t - 5
kap26 [50]

Answer:

h(2)+g(2) = -3

Step-by-step explanation:

h(2) +g(2)\\ \\h(t) = 3-5, g(t) = 2t -5

        Replace the variable  (t)  with (

2)  in the expression.

h (2) = 3 - 5

        Replace the variable  (t)  with (

2)  in the expression.

g(2) = 2(2) -5

        Replace the function designators in h(2) +g(2) with the actual functions.

h(t) = 3 - 5 +2 (2) ← plug h(2) into 2(t)

         Remove parentheses.

3 - 5 + 2(2)

         Multiply 2 by 2

3 - 5 + 4 - 5

         Subtract  5  from  3

.

-2 + 4 - 5

          Add -2 and 4

2 - 5

          Subtract 5 from 2

-3

Answer:

<h2>{7}^{3} (as \: a \: single \: power \: of \: 7)</h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u> </u></em><em><u> </u></em>

{7}^{4}  \div 7

<em><u>Since</u></em><em><u>,</u></em>

{a}^{x}  \div  {a}^{y}  =  {a}^{x - y}

<em><u>Hence</u></em><em><u>,</u></em>

=  {7}^{4 - 3}

=  {7}^{3} (ans)(as \: a \: single \: power \: of \: 7)

Factor this expression completely, then place the factors in the proper location on the grid. 5x3 + 40y6
Molodets [167]
For this case we have the following expression:
 5x3 + 40y6
 Common factor 5:
 5 (x3 + 8y6)
 Factoring the expression within the parenthesis we have:
 5 ((x + 2y2) (x2 - 2xy2 + 4y4))
 Answer:
 
The factored expression is given by:
 
5 ((x + 2y2) (x2 - 2xy2 + 4y4))
