Nicole is half as old as Donald. The sum of their ages is 72.

How old is Nicole, in years?

Answers

Your gonna divide 72 by 2 so therefore you get 36
So that equals to Nicole’s age

Answer:

24 years

Step-by-step explanation:

let Donald's age be x

then Nicole's age would be 1/2 * x = x/2

now, x + x/2 = 72

3x/2 = 72

3x = 72*2

x = 144/3 = 48

Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.

Ella wants to make a fruit salad for herself and 5 friends.

She has 5 cups of grapes, 3 pints of strawberries, and 1 quart of watermelon pieces.

1. How many cups of fruit salad does Ella have?

2. If she wants to share the fruit salad between herself and 5 friends, how much fruit salad will each person get?
Answer both to get brainlest. Also please explain.

Answers

1. I believe she would have 15 cups of fruit salad because it’s 5 cups of grapes, 6 cups strawberries(1 pint = 2 cups which means 6 cups of strawberries) and 4 cups of watermelon (1 pint = 4 cups
2. Since there are 15 cups of fruit salad you would need to divide 15 by the number of friends which would make it 2.5 cups of fruit salad per person

1.) 15 cups
2.) 3 cups per person

Answers

Answer:

11560 ft squared

Step-by-step explanation:

16 x 13 = 208

the equation of straight line passing through the two points (a , b) and (c , d) is

Now f(x) passes through (-4 , 0) and (0 , 4)

the equation is

y=x+4

Now g(x) passes through (-2 , 0) and (0 , 4)

the equation is

y=2x+4

here f(x)=x+4 and g(x)=2x+4

clearly g(x)=f(2x)

Driving Your brother and sister took turns driving on a 635-mile trip that took 11 hours to complete. Your brother drove at a constant speed of 60 miles per hour and your sister drove at a constant speed of 55 miles per hour. Let x be the number of miles your brother drove and let y be the number of miles your sister drove. Solve the linear system x + y = 11 and 60x + 55y = 635 to find the number of miles each of your siblings drove. Show your work.

Answers

Answer: The brother drove 6 hours and the sister drove 5 hours of the trip

Step-by-step explanation:

Your brother drove 35 miles, and your sister drove 600 miles.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have the following system of equations:

x + y = 11 ....(i)

60x + 55y = 635 ....(ii)

Using the elimination method:

Multiply equation 1 by 55, equation 2 by -1, and add both equations together:

55x + 55y = 605, -60x - 55y = -635

Simplify and solve for x: -5x = -30

x = 6

Substitute this value of x back into equation 1 to find y:

y = 11 - 6 = 5

Thus, your brother drove 35 miles, and your sister drove 635 - 35 = 600 miles.

The cost for the number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts were purchased?

Answers

Answer:

6x + 4 - 1/100 = 77.5

Step-by-step explanation:

Inc shipping all shirts 77.49

Shirt individual cost = 12.25

We find the division first = 77.49-3.99 = 73.5 = 73 1/2

Then we divide 73.5 / 12.25 = 6

Then we have our equation

6x + 4 - 1/100 = 77.5

Of the 300 residents interviewed, 203 said no, 7 said yes, and 90 had no opinion.

Which of the following statements is correct for this confidence interval? This confidence interval is valid because a sample size of more than 30 was used. This confidence interval is not valid because the quantity np is too small. This confidence interval is valid because each area resident was asked the same question. The confidence interval is valid because no conditions are required for constructing a large-sample confidence interval for a proportion.
