Answer:

Her daughters age: 1/2x

Step-by-step explanation:

Let's say Rani's present age is x. Her age is twice the age of her daughter.

So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.

1/2(20)=daughter's age

so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.

hope this helped :-) <3

The ratio of the measures of the three angles is 2:6:7. Find the measure of each angle of the triangle.
Tpy6a [65]
Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)

A sinking fund is established to discharge a debt of $20,000 in 15 years. If deposits are made at the end of each 6-month period
Anna71 [15]

Answer:

the amount of each deposit is $45,555

Step-by-step explanation:

The computation of the each deposit is shown below:

Given that

Future value be $20,000

Time period = 15 × 2 = 30

And, the rate = 5% ÷ 2 = 2.5%

Now the formula is as follows

= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1

= ($20,000 × 2.5) ÷ (1 + 0.025)^30 - 1

= $50,000 ÷ 1.0975675791

= $45,555

Hence, the amount of each deposit is $45,555

Find the slope and the​ y-intercept of the line whose equation is 5x+y = −5.
s344n2d4d5 [400]

Answer:

slope is -5

y-intercept is -5

Step-by-step explanation:

Solve for y to write in y=mx+b

m is slope

b is y-intercept

5x+y=-5

Subtract 5x on both sides

    y=-5x-5

slope is -5

y-intercept is -5
