Tina spends 25% of her day in school. She spends 1/3 of her day sleeping. She spends 1/8 of her time at soccer practice. How many free hours does Tina have during the day?

Answers

This will involve adding fractions then subtracting. 25% is equivalent to 1/4. So you'll be adding 1/4 + 1/3 + 1/8. To add fractions you'll need to find a common denominator. 3, 4, & 8 area all factors of 24. So convert your original fractions to 1/4= 6/24, 1/3= 8/24, & 1/8= 3/24. Add your numerators 6+ 8+ 3= 17 which you'll put over the denominator of 24= 17/24. the original question asks how many free hours does she have. their are 24 hours in a day so now you'll subtract 17 from 24. 24-17= 7. She has 7 hours free in a day.

The congruent sides of an isosceles triangle are each 1 unit longer than the length of the shortest side of the triangle. The perimeter of the triangle is the same as the perimeter of a square whose side length is 2 units shorter than the length of the shortest side of the triangle. What is the length of the shortest side of the triangle?

Answers

The length of the shortest side of the triangle is 10cm.

It is given that congruent sides of an isosceles triangle are each 1 unit longer than the length of the shortest side, the perimeter of the triangle is the same as the perimeter of a square whose side length is 2 units shorter than the length of the shortest side of the triangle.

What is congruent triangle?

All three corresponding sides are equal and all the three corresponding angles are equal in measure.

Let's have the variable x be the length of the shortest side.

To equate to demonstrate this problem:

Longer sides of the triangle is (1+x)

Perimeter = (x-2)*4

Therefore, the equation is 4(x-2)=(1+x)+(1+x)+x

Simplify:

4x-8=2+3x

4x=10+3x

x=10

So, the length of the shortest side of the triangle is 10cm.

So let's have the variable x be the length of the shortest side. Then, we make an equation to demonstrate this problem:
Longer sides of the triangle is (1+x)
Perimeter = (x-2)*4
Therefore, the equation is 4(x-2)=(1+x)+(1+x)+x
Simplify:
4x-8=2+3x
4x=10+3x
x=10

The director of marketing at a large company wants to determine if the amount of money spent on internet marketing is a good predictor of company profit. She fits a least-squares regression line to 20 months of data and computes the following regression line:Profit = 372.6 + 17.2(advertising dollars)

What is the value of the residual for advertising dollars spent equal to $1,020 and Profit equal to $17,500? Round to the nearest integer.

Answers

Given:
Profit = 372.60 + 17.2(advertising dollars)
Advertising dollars = 1,020
profit = 17,500

17,500 + residual value = 372.60 + 17.2(1,020)
17,500 + residual value = 372.60 + 17,544
17,500 + residual value = 17,916.60
residual value = 17,916.60 - 17,500
residual value = 416.60

residual value is 416.60 or 417 rounded off to the nearest integer
