Answer:

7c + 28

Step-by-step explanation:

You just have to multiply 7 with the variable and the number in parenthesis while keeping the plus sign between the two products that you get.

Answer:

That is correct

Step-by-step explanation:

Answer:

Answer is 40

Step-by-step explanation:

literally all you have to do is subtract 70 - 30 = 40

so your answer would be 40 another way is 30 + 40 = 70

just have to see what number would get you to 70 if you did the problem the second way.

Answer:

First answer =10y+2y²-6y³+8y³=

=10y+2y²+2y³=

=2y³+2y²+10y

Answer:

40.5 inches

Step-by-step explanation:

I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.

Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.

February and March combined: 8.5+5.1 = 13.6

Since the question asked how much more, that means you subtract:

26.9 - 13.6 = 13.3

hope this helped =)

Answer:

1a) 3203.125

1b) 1137.5

2a) 8

Step-by-step explanation:

1a)

rectangular prism = cuboid = 4 rectangles and 2 squares

how much water it can hold = volume of cuboid (length x width x height)

length = 20.25

width = 12.5 (because all sides of a square is the same)

height= 12.5

20.5 x 12.5 x 12.5 = 3203.125(what ever unit you use)

1b) how much wrapping paper = surface area = the sum of the area of each side

4 rectangles = 4(20.5 x 12.5) 1025

2 squares = 2(12.5 x 12.5) 312.5

1025 + 312.5 = 1137.5 (preferred unit ^ 2)

Answer:

400/ 81

Step-by-step explanation:

16/25 × (5/3)^4

16/25 × (625/ 81)

10000/ 2025

400/81

The value of A/B is given as follows:

A/B = -2.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Step-by-step explanation:

First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.

Question 17

Using a calculator, you get 6.48074069… for your decimal.

Rounding it to the nearest tenth, your answer would be 6.5

Now, to find the two consecutive whole numbers the square root is between…

However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.

Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!

Question 18

Using a calculator, you get 9.380833151… for your decimal.

This rounds to 9.4

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.

In non-decimal form (simplified radical), your answer can be 2√22.

Question 19

Using a calculator, you get 7.93725393… for your decimal.

This rounds to 7.9

The whole numbers surrounding this decimal are 7 and 8.

You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.

In non-decimal form (simplified radical), your answer can be 3√7.

Question 20

Using a calculator, you get 8.66025403… for your decimal.

This rounds to 8.7

The whole numbers surrounding this decimal are 8 and 9.

You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.

In non-decimal form (simplified radical), your answer can be 5√3.

Question 21

Using a calculator, you get 5.47722557… for your decimal.

This rounds to 5.5

The whole numbers surrounding this decimal are 5 and 6.

You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.

Question 22

Using a calculator, you get 9.84885780… for your decimal.

This rounds to 9.8

The whole numbers surrounding this decimal are 9 and 10.

You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.

Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, \(2^2\), or 2 to the power of 2.

Answer:

0.18 cm²

Step-by-step explanation:

Given that a rectangle and a triangle have same perimeter . The sides of them are ,

\(\begin{cases} Square = 4cm , 4cm , 3cm \ and \ 3cm .\\ Triangle = 4cm , 5.8cm \ and \ 4.2cm \end{cases}\)

We know that area of rectangle is product of length and breadth.

\(\implies Area = length \times breadth \\\\\implies Area = 4cm \times 3cm\\\\\implies \red{ Area = 12cm^2}\)

Also we know that the area of triange is half the product of base and height . So that ,

\(\implies Area = \dfrac{1}{2}\times 5.8cm \times 4.2 cm \\\\\implies \red{ Area = 12.18 cm^2 }\)

Therefore the difference between them is ,

\(\implies D = A_1 - A_1 \\\\\implies D = 12.18cm^2-12cm^2 \\\\\implies \red{D = 0.18 cm^2}\)

Answer:

34,28 ft

Step-by-step explanation:

This figure is formed from a rectangle and a semi-circle

Opposite sides of a rectangle are equal

This figure's perimeter is the sum of all side lengths:

2 sides of 12 ft

1 side of 4 ft

Half of the circumference

d (diameter) = 4 ft

r (radius) = 0,5 × 4 = 2 ft

First, we have to find the half of the circumference (C):

\(0.5c = (2\pi \times r\))/2

\(0.5c = (2 \times 3.14 \times 2)/2 = 6,28\)

Now, we can find the perimeter of the given figure:

P = 6,28 + 12 + 12 + 4 = 34,28 ft

The answer for

x=3/4

y=3/2

Step-by-step explanation:

let bigger number be x

let the smaller number be y

x+y=3¾

x+y=15/4

x=15/4-y

x+1/2=2/3y

x+1/2=2y/3

15/4-y=2y/3

C.LT.

-y-2y/3= -15/4

-3y-2y/3= -15/4

-5y/3= -15/4

-5y×4=3×-15

-20y= -45

divide both sides by-20

-20y/-20= -45/-20

y=9/4

x+y=15/4

x=15/4-y

x=15/4-9/4

x=6/4

x=3/2

Answer:

1) This linear equation has a slope of 60

2) (2, 120)

3) \(y - 120 = m(x - 2)\)

Step-by-step explanation:

1) This situation represents a linear time-distance relationship where:

   x represents the time

   y represents the distance travelled

   Slope is equal to △y/△x

   Substituted form: \(\frac{120}{2}\)

   Slope is equal to 60.

2) Using the statement:

She has driven for 2 hours and has traveled a distance of 120 miles, we know that knowing that x represents the time and y represents the distance:

A possible coordinate is (2, 120)

3) Using the point slope standard equation and our known values, we can substitute the values. The correct answer is  y - 120 = m(x - 2)
