Answer:

DF = 20.4

Step-by-step explanation:

The figure given is a kite.

A kite has two set of opposite sides that are congruent. And the diagonals bisect each other. Thus,

∆DEH is congruent to ∆FEH, therefore, DH = HF

Use pythagorean theorem to find DH:

DH² = DE² - EH²

DH² = 15² - 11²

DH² = 104

DH = √104

DH = 10.2 (nearest tenth)

DF = 2(DH)

DF = 2(10.2)

DF = 20.4

48 girls, 41 boys, and 5 teachers sat in the gym. Write the ratio of girls to boys in three ways.
Anika [276]

Answer:

D

Step-by-step explanation:

The answer is D because the question is asking for girls to boys. So anything that has 5 in it is wrong because it isn't asking for teachers, which eliminates A. So since it is asking <u>girls</u><u> </u><u>to</u><u> </u><u>boys</u> the number order has to be 48 then 41 because it is asking for girls first then to boys. So that makes B wrong. When it comes to the fraction part of the ratio the first number it is asking for (which is girls) <em><u>alwa</u><u>ys</u></em> goes on top. So that eliminates C which leaves only answer to be D.

The total value of the account is based on the function f(x) = q • 1.025x, where x represents the number of years the money has
Harman [31]
Would it not just be q? Since I am assuming that 1.025 is the interest rate of the bank hence why it would be multiplied by the year.

(3x+9)^5=32x^5<br> help solve for x
makvit [3.9K]
Answer:
x = -9

Explanation:

(3x + 9)^5 = 32x^5

(3 (x + 3))^5 = 32x^5

3^5 (x + 3)^5 = 32x^5

243(x + 3)^5 = 32x^5

243(x + 3)^5 - 32x^5 = 0

x = -9
