What is the solution(s) to the equation 5a2 - 44 = 81?

taurus [48]

Answer:

Step-by-step explanation:

5a^2 - 44 = 81 Add 44 to both sides

5a^2 = 81 + 44 Collect like terms

5a^2 = 125 Divide both sides by 5

a^2 = 125/5

a^2 = 25 Take the square root of both sides

√a^2 = √25

a = +5

a = -5

The answer is B

How do I find the ratio of this? It makes no sense to me

Volgvan

Answer:

$\frac{169}{289}$

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = a² : b²

Here ratio of sides = 52 : 68 = 13 : 17 ← in simplest form, thus

ratio of areas = 13² : 17² = 169 : 289 = $\frac{169}{289}$

Solve.<br><br> Round to the nearest hundredth.<br><br> 29.3 = 1.7y

Elena-2011 [213]

Steps to Solve:

29.3 = 1.7y

29.3/1.7 = 1.7y/1.7

y = 17.2352941176

In this case, we round up the hundredths place because the number in the thousandths place is 5 or higher.

y = 17.24

Hope this helps!! :)
