Answers

Answer:

360ft^2

Step-by-step explanation:

We know that the height is always 8 ft. So lets find the area of two of the 4 walls.

We multiply by 2 because there are two of the same wall.

2(8ft x 10ft) = 160ft^2

Now lets find the area of the other wall.

2(8ft x 15ft) = 240ft^2

Now we add it up

160 + 240 = 400

400ft^2

But wait! We aren't done yet! We still have to subtract out the door and window which is 60ft^2.

400 - 60 = 360

360ft^2

help me find the perimeter plzzz!

Answers

Answer:

2m-4

Step-by-step explanation:

double both of them and just simplify

the first one will become (6m-12) and the second will become (-4m+8)

subtract 6m and -4m so it's 2m

subtract -12 and 8 so it's -4

so the answer is 2m-4

Answer:

B. 2m - 4

Step-by-step explanation:

When simplifying the expression (3m - 6) + (3m - 6) + (-2m + 4 ) + (-2m + 4) while trying to find the perimeter, you will find your answer to be 2m - 4.

3. The sum of the two numbers is5/9
If one of the numbers is
1/3 find the other ​

Answers

Step-by-step explanation:

let the one number be X.

and

second one 1/3

then

1/3 +X = 5/9

X = 5/9-1/3

X =( 5-3) /9

X = 2/9 Ans

Answer:

The other number will be 2/9.

Step-by-step explanation:

Let the second fraction be x :

[tex]x = \frac{5}{9} - \frac{1}{3} [/tex]

[tex]x = \frac{5}{9} - \frac{3}{9} [/tex]

solve (2x-10)=(65-x) show your work plz!

Answers

Answer: x=25

Step-by-step explanation:

Simplifying

(2x + -10) = (65 + -1x)

Reorder the terms:

(-10 + 2x) = (65 + -1x)

Remove parenthesis around (-10 + 2x)

-10 + 2x = (65 + -1x)

Remove parenthesis around (65 + -1x)

-10 + 2x = 65 + -1x

Solving

-10 + 2x = 65 + -1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.

-10 + 2x + x = 65 + -1x + x

Combine like terms: 2x + x = 3x

-10 + 3x = 65 + -1x + x

Combine like terms: -1x + x = 0

-10 + 3x = 65 + 0

-10 + 3x = 65

Add '10' to each side of the equation.

-10 + 10 + 3x = 65 + 10

Combine like terms: -10 + 10 = 0

0 + 3x = 65 + 10

3x = 65 + 10

Combine like terms: 65 + 10 = 75

3x = 75

Divide each side by '3'.

x = 25

Simplifying

x = 25

Sorry if its too confusing!

Answer:

Your slope would be 3.

Step-by-step explanation:

To find the slope from two points, you would need to use the formula: y2-y1/x2-x1

In this case, the equation would look like -2-7/5-8.

-2 - 7 = -9

5 - 8 = -3

Answer:

y = 2x + 4

Step-by-step explanation:

y = mx+b

m represents the slope, and b is the y-intercept

The slope is 2 as it's going up 2 unit squares each time, and the b is 4 because that's where the y-axis gets intercepted.

so the answer is y = 2x + 4

The length of segment AE is 5 centimeters.
a. what is the length of segment CD?
b. what is the length of segment AB?
c. Name a segment that had the same length as segment AB. segment________​

Answers

Answer/Step-by-step explanation:

Segment AE is a radius of the circle with center of A.

Any segment that has its origin from the center of the Circle, A, and meets at any point along the circumference of the circle, is equally a radius, and would have the same length as segment AE.

Thus:

a. Length of segment CD:

Segment CD is half of the circle. So it is the diameter of the circle.

Diameter of a circle = 2 × length of the radius.

Therefore,

CD = 2 × AE

CD = 2 × 5 (substitution)

CD = 10 cm

b. AB is a radius.

Therefore, AB = AE

AB = 5 cm

c. Any of these segments are also radius of the circle and also have the same length as segment AB:

Segment AG,

Segment AD

Segment FA

Segment AC

A public parking garage charges $5, plus an additional $2 per hour.
Choose the graph of the line.

Answers

Answer:

2nd one

Step-by-step explanation:

Graph-2 is correct line that represents the parking charge of the public garage.

What is a linear equation?

A linear equation is an equation where the variable has the highest degree of 1.

Given, a public parking garage charges $5, plus an additional $2 per hour.

For 1 hour, the total cost will be = $(5 + 2 × 1) = $7.

For 2 hours, the total cost will be = $(5 + 2 × 2) = $9.

For 3 hours, the total cost will be = $(5 + 2 × 3) = $11.

For 4 hours, the total cost will be = $(5 + 2 × 4) = $13.

For 5 hours, the total cost will be = $(5 + 2 × 5) = $15.

Here, the increase in parking cost is in the form of linear equation and it increases $2 with the increase in every hour.

Therefore, graph-2 represents the actual line of cost of the parking charge and time.

Sophie and Isadora ride around a circular track that has an inner radius of 30 m. The track is 2 m wide and Isadora rides along the outer lane. How much further does Isadora ride than Sophie, In one lap? Is any one else as confused as I am?

Answers

it’s just the difference in circumferences, so it’d be
S = 2 Pi r
S = 2 * 3.14 * 30
S = 188.4m

I = 2 Pi r
I = 2 * 3.14 * (30 + 2)
I = 200.96m

I - S = 200.96 - 188.4
= 12.56m

Therefore, Isadora had to ride 12.56m more than Sophie
