The ratio of the interior angle measures of a triangle is 2:3:5. what are the angle measures?
In-s [12.5K]
The solution we will need to go is 2x + 3x + 5x = 180

10x = 180
x = 180/10
x = 18
2x = 36
3x = 54
5x = 90

(Just substitute that 18 on the x and it will give you the answer for the measurement of the angle measures.

Imani spent half of her weekly allowance playing Mini-golf.To warm more money her parents let her wash the car for $4. What is h
Sergio [31]

Answer:

her weekly allowance is $16

Step-by-step explanation:

Let x represent Imani's weekly allowance.

Imani spent half of her weekly allowance playing Mini-golf. This means that the total amount that she spent playing Mini-golf is x/2. The amount that she is left with would be

x - x/2 = x/2

In order to earn more money her parents let her wash the car for $4. This means that the total amount left with her is

x/2 + 4

if she ended with $12, it means that

x/2 + 4 = 12

x/2 = 12 - 4 = 8

x = 2 × 8 = $16

What is the following quotient? ^3 square root 60 over ^3 square root of 20
prohojiy [21]

Answer:

\sqrt{3} is the required quotient.

Step-by-step explanation:

We have been given the expression:

\frac{3\sqrt{60}}{3\sqrt{20}}

Cancel the common term which is 3 we will be left with

\frac{\sqrt{60}}{\sqrt{20}}

\sqrt{60} can be written as after prime factorization is:

2\sqrt{15}

And \sqrt{20} can be written as after prime factorization is:

2\sqrt{5}

Hence, the given expression would become after 2 gets cancel from numerator and denominator:

\frac{\sqrt{3}\cdot \sqrt{5}}{\sqrt{5}}

Quotient is the answer we get after dividing numerator by denominator and cancel common term which is \sqrt{5}

\sqrt{3} is the required quotient.
