WILL GIVE BRAINLIST SOON AS I CAN I DONT UNDERSTAND THIS, PLZ HELP​
allochka39001 [22]

Answer:

b = 7\sqrt{3}

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for b

and the exact value

tan30° = \frac{1}{\sqrt{3} }, thus

tan30° = \frac{opposite}{adjacent} = \frac{7}{b} and

\frac{7}{b} = \frac{1}{\sqrt{3} } ( cross- multiply )

b = 7\sqrt{3}

How do you simplify 2i<6u ?
marusya05 [52]
In simplifying inequalities, there are a few things that you have to remember. Here are some:

<span>Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.
But these things will change direction of the inequality:<span>Don't multiply or divide by a variable (unless you know it is always positive or always negative)

We simplify as follows:
2i/2<6u/2
i<3u</span></span>

4. The volume of the ball is 3052.08. What is its radius?
Olin [163]

Answer:

Step-by-step explanation:

v=4pi*r^3/3=3052.08

4*3.14/3*r^3=3052.08

4.2*r^3=3052.08

r^3=3052.08/4.2=726.7

so r ≈9

Joyce took out a small loan for $1,200. The interest on the loan was 10.5%, but she paid it off in just 18 months. How much did
jasenka [17]

Answer:

She paid back $192 in interest

Step-by-step explanation:

A = P(1+r)^n

P = $1,200

r = 10.5% = 0.105

n = 18 months = 18/12 = 1.5 years

A = 1,200(1+0.105)^1.5 = 1,200(1.105)^1.5 = 1,200×1.16 = 1,392

Amount = $1,392

Principal = $1,200

Interest = amount - principal = $1,392 - $1,200 = $192
