Students from Oak Middle School and Lake Middle School are holding a car wash to raise money for charity. The expression 70 +60 represents the amount Oak Middle School raises. The
expression By + 30 represents the amount Lake Middle School raises. Which expression shows the total amount the two schools raise?
15x90
Soxy90
O 7x+By90
15190

Answers

The expression that shows the total amount the two schools raise is 7x + 8y + 90.

What is an expression?

It should be noted that an expression is simply used to show the relationship between the variables that are used.

From the information, the expression 7x +60 represents the amount Oak Middle School raises and the expression 8y + 30 represents the amount Lake Middle School raises.

Therefore, the total amount will be:

= 7x + 60 + 8y + 30

= 7x + 8y + 90

The total amount is 7x + 8y + 90.

what number is closer to 693? 630 or 720?

Answers

Answer: 720

Step-by-step explanation: So this question really is just about subtraction and addition so as you can tell 630 is lower than 693 so if you add to where it is a 693 you need to add 63. But if you look at 720 its higher so you need to subtract and if you subtract to 693 then you need to subtract 27. So 27 is less than 63.

A cube has a surface area of 150
cm squared. Find the side length of the cube in cm.

Answers

Answer:

Step-by-step explanation:

6 faces have an area of 150 cm^2

1 face has an area of 150/6 = 25 cm^2

The formula for the area of one face of a cube = s^2 which is the length of  a side squared.

s^2 = 25

sqrt(s^2) = sqrt(25)

s = 5

What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 6.5? (5 points)

A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm.
Perimeter = 54 cm, area = 181.25 cm2
Perimeter = 54 cm, area = 2,028 cm2
Perimeter = 182 cm, area = 2,028 cm2
Perimeter = 182 cm, area = 181.25 cm2

Answers

Answer:

Perimeter = 182 cm, area = 2,028 cm2

Step-by-step explanation:

original perimeter=2*(8+6)+28 cm

original area=8*6= 48 cm²

You would have to do the old length and width times the scale factor

Multiply both of the width's

8 * 6.5 = 52 cm

scale factor: 6 * 6.5 = 39 cm

To get perimeter = 2(length + width)

2(52+39)=182 cm.

So you would have to do length(52 cm) * width(39 cm)

To get 2028 cm^2

Maya has 54 cubic feet in her garden she already has 4.5 cublc feet of soil .Soil bags have 1.5 how many bags should maya purchace.

Answers

Answer: 33

Step-by-step explanation:

The cubic feet needed is 54 and she already has 4.5 cubic feet of soil. This mean that she will need 49.5 more.

= 54 - 4.5

= 49.5

Since each soil bag has 1.5, the number of soil bags needed will be:

= 49.5 / 1.5.

= 33

Therefore, she'll need 33 bags

Select all the expressions that are equivalent to 24x + 12.
2(12x + 6)
–6(–4x – 2)
–3(8x – 4)
12(1 + 2x)
–4(–6 – 3x)

Answers

Answer:

2(12x + 6)

-6(-4x - 2)

12(1 + 2x)

The expressions that are equivalent to 24x + 12 are:

2(12x + 6)

-6(-4x - 2)

12(1 + 2x)

Let's go through each expression and simplify them to determine if they are equivalent to 24x + 12.

2(12x + 6):

We can use the distributive property to simplify this expression:

2 * 12x + 2 * 6 = 24x + 12

This expression is equivalent to 24x + 12.

–6(–4x – 2):

Again, using the distributive property, we simplify:

–6 * –4x + –6 * –2 = 24x + 12

This expression is equivalent to 24x + 12.

–3(8x – 4):

Once again, applying the distributive property:

–3 * 8x + –3 * –4 = –24x + 12

This expression is not equivalent to 24x + 12.

12(1 + 2x):

Using the distributive property:

12 * 1 + 12 * 2x = 12 + 24x = 24x + 12

This expression is equivalent to 24x + 12.

–4(–6 – 3x):

Applying the distributive property:

–4 * –6 + –4 * –3x = 24 + 12x = 12x + 24

This expression is not equivalent to 24x + 12.

Jim invests $1240 at a 3.6 interest rate in an account that is compounded quarterly. What is the value of the account after 6 years

Answers

Answer:

$1507.84

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.6%/100 = 0.036 per year,

then, solving our equation

I = 1240 × 0.036 × 6 = 267.84

I = $ 267.84

The simple interest accumulated

on a principal of $ 1,240.00

at a rate of 3.6% per year

for 6 years is $ 267.84.
