Answers

Answer 1

Answer:

The leading coefficient is 15

The constant is -6

Step-by-step explanation:

So first open up all the parentheses:

[tex]8r^3+2r^2+1-7+7r^3-3r^2 = 15r^3-r^2-6[/tex]

The leading coefficient is 15

The constant is -6

Kim’s family spends $62.50 on dinner. They leave an 18% tip. How much is their total bill after tip?

Answers

Answer:

51.25

Step-by-step explanation:

Multiply 62.5 by .18. You get 11.25. Subtract that from 62.5 and you get 51.25.

Answer:

Multiply the price with the tip rate

18% = 0.18

62.5 x 0.18 = 11.25

that is the tip. We add that on to find the total price

62.5 + 11.25 = 73.75

73.75 dollars is the answer. Hope this helps

AB is a segment with one endpoint A(-7,9) and midpoint M(8,1). Can
you find the coordinates of the other endpoint B?
Enter the x-coordinate of the other endpoint here
Enter the x-coordinate of the other endpoint here​

Answers

Answer:

x-coordinate of the other endpoint: 23

y-coordinate of the other endpoint: -7

Step-by-step explanation:

To find the x-coordinate of the other endpoint, we need to find the run between the known endpoint and the midpoint

run: xM - xA = 8 - (-7) = 15

where xM and xA are the x-coordinates of M and A respectively.

The run between the other endpoint and the midpoint must be the same as before:

x - 8 = 15

x = 15 + 8

x = 23

To find the y-coordinate of the other endpoint, we need to find the rise between the known endpoint and the midpoint

rise: yM - yA1 =  - 9 = -8

where yM and yA are the y-coordinates of M and A respectively.

The rise between the other endpoint and the midpoint must be the same as before:

y - 1 = -8

y = -8 +1

y = -7

Jason wants to cut a rope that is 60 feet long into several equal pieces with nothing left over. How many pieces will he have if the length of each piece is the greatest integer possible?

Answers

Answer:

2 pieces, 30ft each

Step-by-step explanation:

rope : 60ft long

we are trying to figure out how many equal pieces we can cut the rope into with the length of each piece to be the greatest possible integer:

if jason wants the length of rope to be the longest than the answer is 2, if he divides the length of 60 by 2, each piece will be 30 feet long. If he divides the rope by any number larger, each piece will be shorter than 30 feet, and he wants the piece to be the largest possible length.

Answer

How many solutions does the following system of equations have? y=5/2x+2 and 2y=5x+8

Answers

Answer:

No solutions.

Step-by-step explanation:

y = 5/2x + 2

2y = 5x + 8

Plug the first equation into the second.

2(5/2x + 2) = 5x +8

5x + 4 = 5x + 8

5x + 4 cannot equal 5x + 8, so this system of equations has no solutions.

What is the value of the 3 in 630

Answers

Answer:

hey mate, here is your answer. Hope it helps you.

Step-by-step explanation:

We can write 630 in expanded form as:

630 = 600 + 30 + 0

and in words:

630 = 6 hundreds, 3 tens and zero ones

the value 6 is 600

and the place value of 3 is 30 and the face value is 3 in the number 630.

The number can be written in the expanded form as 600 + 30 + 0 and the face value is 3 in the number 630.

What is the number?

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

The number is 630

As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

The number 630 can be written as:

630 = 6x100 + 3x10 + 0x1

630 = 600 + 30 + 0

The above expression represents the expanded form of the number 630.

In words:

630 = 6 hundred, 3 tens, and zero ones

The value 6 is 600

The place value of 3 is 30 and the face value is 3 in the number 630.

Thus, the number can be written in the expanded form as 600 + 30 + 0 and the face value is 3 in the number 630.

The diagram shows a cuboid.
The height of the cuboid is 6cm.
The volume is 90cm3

What is the area of the shaded face?

Answers

Answer:

The area of the face is 15 cm^2

Step-by-step explanation:

The formula for volume is

V = Bh  where B is the area of the base and h is the height

90 = B * 6

Divide each side by 6

90/6 = 6B/6

15 = B

The area of the face is 15 cm^2

Answer:

15cm^2

Step-by-step explanation:

width will be 6cm since its side face is square.

V=lwh

90cm^3=l*6cm*6cm

90cm^3=36cm^2*l

l=90cm^3/36cm^2

l=2.5cm

so the area of the shaded face will be..

A=l×W

A=2.5cm*6cm

A=15cm^2

An isosceles triangle has two congruent side lengths of 20 inches.
The base of the triangle has a length of 32 inches. What is the height of the
triangle?
12 inches
10 inches
15 inches

Answers

Answer:

h = 12

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

The legs are 32/2 = 16 and the height h

The hypotenuse is 20

16^2 + h^2 = 20^2

256 + h^2 = 400

h^2 = 400-256

h^2 = 144

Taking the square root of each side

h = sqrt(144)

h =12
