a racecar speeds down the highway at a constant velocity. if it travels 3,500 m in 60 seconds, what is the velocity of the racecar?

Answer: 45

Step-by-step explanation:

4x-15 = x+30

   3x = 45

     x = 15

Then plug 15 into the  equation to get the answer of 45.

Answer:

1°

Step-by-step explanation:

There are 360 degrees in a circle.

Thus, if a circle turns x degrees, then it will represent x/360 of the entire circle.

Since the rotation represented 1/360 of the entire circle, this means that the measure of the angle must be only 1 degree.

Answer:180

Step-by-step explanation:

An angle turns through n one degree angles is said to have an angle measure of n degrees

Answer:

See Below

Step-by-step explanation:

150 = p + 78    ------ you want to get the p to one side and the other number the the other side of the =

(78 - 150) = p (78 - 78)   ---- what ever you do to one side you do to the other

72 = p

s - 51 = 12 (same thing as above)

s (-51 + 51)  = 12 + 51

s = 63

65 = blank + 7 ( you can put a letter like x or y because they number is not determined yet)

65 = x + 7 (same as above)

( 7 - 65 ) = x ( 7 - 7 )

58 = x

Step-by-step explanation:

A geometric sequence is a sequence where you keep multiplying a term by the ratio to generate the next one.

The first term is 3/4

Let n0 = 3/4

The next term is n1.

To get n1 we must multiply n0 by the ratio 4.

● n1 = n0×4

This formula gives us the second term. We need a general one that can generate all the terms of the sequence.

Let S(n) be a term of this sequence.

To get n we have multiplied n0 (the first term) by 4 (the ratio) one or many times. Precisely, n times.

So:

● S(n )= n0 ×4^n

no is 3/4

● S(n)= (3/4) × 4^n

This formula generates any term from this geometric sequence. If you want to calculate the 77th term then just replace n with 77.

Answer:

Step-by-step explanation:

To find the next term, multiply the previous term by constant ratio

a₁ = 3/4

[tex]a_{2}=\frac{3}{4}*4=3*1 = 3\\[/tex]

a₃ = a₂ * constant ratio = 3 * 4 = 12

a₄ = a₃ * constant ratio = 12 *4 = 48

Geometric sequence :

The measure of length DE if DF = 61 and EF = 18 is 43

From the question, we are given the following measurement:

DF = 61

EF = 18

Required:

DE

Using the expression to find the measure of DE

DE + EF = DF

Substitute the given values

DE + 18 = 61

Subtract 18 from both sides

DE + 18 - 18 = 61 - 18

DE = 43

Hence the measure of DE is 43

Answer:

N(- 16, 14 )

Step-by-step explanation:

Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex](x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ )

Use this formula and equate to the coordinates of the midpoint P

let the coordinates of N = (x, y ), then

[tex]\frac{1}{2}[/tex](8 + x ) = - 4 ( multiply both sides by 2 )

8 + x = - 8 ( subtract 8 from both sides )

x = - 16

[tex]\frac{1}{2}[/tex] (- 2 + y ) = 6 ( multiply both sides by 2 )

- 2 + y = 12 ( add 2 to both sides )

y = 14

Thus

coordinates of N = (- 16, 14 )

Answer:

6.25 inch by 20/3 inch (6.67 inch).

Explanation:

Use the scale as a conversion factor.

Scale: 1 inch = 12 feet

Conversion factor: by the division property of equaltiy you can divide each side by 12 feet

1 inch / 12 feet = 1

Convert 75 feet:

75 feet × 1 inch / 12 feet = 6.25 inch

Convert 80 feet:

80 feet × 1 inch / 12 feet = 20/3 inch ≈ 6.67 inch

Thus, the dimesions to make a scales drawing of 75 feet by 80 feet are 6.25 inch and 20/3 inch (6.67 inch).

Answer:

B

Step-by-step explanation:

by a rule of angles in parallel lines we have that

angle 4 + angle 5 =180

so we have

(3x+15)+(2x-10)=180

(3+2)x+(15-10)=180

5x+5=180

5(x+1)=180

x+1=36

x=36-1

x=35

Answer:

B. 35

Step-by-step explanation:

<4 and <5 are supplementary angles and their sum is = 180°

3x + 15 + 2x - 10 = 180 add like terms

5x + 5 = 180

5x = 175

x = 35

Part A:

Since five states have four-star hotels, only those five states can claim at least one four-star hotel and since there are 50 states, we can write this as 5/50 or 1/10.

Part B:

50 - 5 = 45 states don't have a four-star hotel.

Part C:

45/50 or 9/10 of the states do not have a four-star hotel.

Best of Luck!

Answer:

The fraction of states with a​ four-star hotel 9/10.

The number of states without a​ four-star hotel is 5

The fraction of states without a​ four-star hotel is 1/10

Answer:

Step-by-step explanation:

They are vertical angles, and vertical angles are always equal, so set them equal to each other

2x + 1 = 55

Subtract one

2x = 54

Divide by 2

x = 27

Answer:

x = 27

Step-by-step explanation:

Its a vertical pair or angles so they equal each other.

55 = (2x + 1)

Get rid of parentheses.

55 = 2x + 1

Subtract 1 on both sides.

54 = 2x

Divide 2 on both sides.

x = 27

Answer:

u is 4 and v is 18

Answer:

v = 18 ; u = 4

Step-by-step explanation:

In a parallelogram , the diagonals bisect each other . So,

v/3 = 6 ................ eqn.1

and

2u + 2 = 5u - 10 ................. eqn.2

From eqn.1,

v/3 = 6

=> v = 6×3 = 18

From eqn.2,

2u + 2 = 5u - 10

=> 5u - 2u = 10 + 2

=> 3u = 12

=> u = 4

Answer:

The hole is 9 inches deep

Step-by-step explanation:

Volume of a cubicle hole = a^3

Where a= side edge of the cube

Volume of dirt removed = 729 cubic inches

How many inches deep is the hole

Volume of a cubicle hole = a^3

729 = a^3

Find the cube root of both sides

3√729 = 3√ a^3

9 = a

a= 9 inches

The hole is 9 inches deep

Check:

Answer:

1. 9 feet

2. The ground

3. Absolute values of opposite numbers are the same

Step-by-step explanation:

Given

Distance up the apple tree = 9 feet up

Solving (a): How far he'll climb to come down

In this case, the distance from the ground up to the tree is the same distance back to the ground.

In other words;

Since he climbs 9 feet up, then he'll climb 9 feet down to the ground

Solving (b): What 0 represents

In this case, 0 represents the ground

Solving (c): Absolute values

The absolute values of opposite numbers (from negative to positive) are the same

Take for instance:

[tex]|-9| = 9[/tex]

[tex]|-3| = 3[/tex]

And so on...

Step-by-step explanation:

GCF is literally abbreviated to "Greatest Common Factor". In order for two numbers to have the same GCF they must have a number that they both could be multiplied by.

I also suggest using a factor tree. Super useful when figuring out the rest of the common factors.
