Bill's new porch is rectangular, with an area of 50 square feet. If the length of the porch is two times the width, what is the perimeter of the porch?
A.30
B.40
C.50
D.60

Answers

the answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.

If 48% of the students in a certain college are female and there are 2,400 female students, how many students are male?

Answers

Answer:

2,600 male students

Step-by-step explanation:

[tex]\frac{2,400}{0.48} = 5,000[/tex]

There are 5,000 students in total.

Since 2,400 of them are female, the remaining students must be male.

5,000 - 2,400 = 2,600 male students

Nick is on his school's swim team. During his 2-week winter break, he swims 30 laps each week to stay in shape. If each lap is 25 yards, how many feet does he swim during his winter break? Feet

Answers

Answer:

3900 feet

Step-by-step explanation:

Steps to answer this question

We are to convert yards to feet Multiply laps sum by two to determine the number of laps he swam in two weeksthen multiply figures gotten from 1 and 2

1 yard = 3 foot

25 yards = 25 x 3 = 65 foot

total yards swam = 30 x 2 = 60

60 x 65 = 3900

Tom drives 200 miles in 4 hours.
He drives the first 32 miles at an average speed of 64 mph
Work out his average speed for the rest of the journey, in mph.
Please help??

Answers

His average speed for the rest of the journey was of 48mph.

if tom is driving 200 miles in 4 hours... and drives the first 32 miles in half an hour... his speed for the rest of the trip would most likely be 48 mph because 3.5 hours are left and 168 miles are left and when you divide that it comes out to 48.

What is an expression?

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the data given in the question,

The total amount Kiran is having in the bank = $100

He needs to have at least $25 in the account at the end of the year.

So, the money he can spend in a year = $100 - $25 = $75

1 year = 12 months

So, the amount of money spent per month will be,

75/12 = $6.25

Answer:

x = 3.6

Step-by-step explanation:

It can be helpful to write down corresponding sides and their measures.

AB = 5, PQ = 6

BC = 3, QR = x

CD = 2, RS = 2.4

DA = 4, SP = 4.8

Then you can look for easy ways to find x. You can tell from this table that all of the values in PQRS are 6/5 = 1.2 times the corresponding values in ABCD.

Then ...

QR = 1.2×BC = 1.2×3

QR = x = 3.6

_____

Other ways you can figure x are ...

x/BC = PQ/AB

x = (BC)(PQ/AB) = 3(6/5) = 3.6 . . . . the method we used

x/RS = BC/CD

x = 2.4(3/2) = 3.6

x/SP = BC/DA

x = 4.8(3/4) = 3.6

Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?

Answers

Answer:

(a) The possible dimensions are:

1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

(b): Patio with greatest and the least perimeter

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

Step-by-step explanation:

Given

[tex]Tiles = 72[/tex]

Solving (a): Possible rectangular models

To do this, we simply list out the possible factor pairs of 72.

So, we have:

1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

Solving (a): Models with the least and the greatest perimeter

Perimeter (P) is calculated using:

[tex]P = 2 * (L + W)[/tex]

So:

1 unit by 72 units;

[tex]P = 2 *(1 + 72) = 146 units[/tex]

2 units by 36 units;

[tex]P = 2 *(2 + 36) = 76 units[/tex]

3 units by 24 units;

[tex]P = 2 *(3 + 24) = 54 units[/tex]

4 units by 18 units;

[tex]P = 2 *(4 + 18) = 44 units[/tex]

6 units by 12 units;

[tex]P = 2 *(6 + 12) = 36 units[/tex]

8 units by 9 units

[tex]P = 2 *(8 + 9) = 34 units[/tex]

From the calculations above:

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

To find:

The missing values.

Solution:

We have,

It can be written as

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11}{19}n+\dfrac{1}{19}n\right)+\left(-8+10\right)[/tex]

So, the values for the first two boxes are [tex]\dfrac{11}{19}n[/tex] and 10 respectively.

On simplification, we get

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11+1}{19}n\right)+\left(2\right)[/tex]

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\dfrac{12}{19}n+2[/tex]

So, the values for third and fourth boxes are [tex]\dfrac{12}{19}[/tex] and 2 respectively.

Fill in the parenthesis for the equation of the circle:
(Blank 1)² +(Blank 2)²= (Blank 3)

*Just type what you would write in the parentheses with no spaces

Answers

Answer:

(x + 10)² + (y + 4)² = 232

Step-by-step explanation:

Given Center = (-10, -4)Point on circle = (4, 2)To find The equation of circleSolution

Remember the standard equation of circle:

(x - h)² + (y - k)² = r², where (h, k) is the center and r is radius

We have

h = -10, k = -4

Use distance formula (Pythagorean theorem) to work out the length of the radius. We know that radius is the distance from the center to any point on the circle.

Here we are finding the distance between points (-10, -4) and (4, 2)

r² = (-10 - 4)² + (-4 - 2)² r² = 14² + 6²r² = 232

So the equation is:

(x + 10)² + (y + 4)² = 232

Solve for x, rounding to the nearest hundredth.
