Answer 1

Answer:

ths for the points TEHEHEHEHE

Step-by-step explanation:

Answer 2

Answer:

P = 12x - 18, x = 7 feet

Step-by-step explanation:

We know that the formula for the perimeter of a rectangle is:

[tex]P=2l+2w[/tex]

Where l is the length and w is the width. So we just substitute in for variables:

P = 2 (5x - 7) + 2 (x - 2)

We distribute by foiling:

P = 10x - 14 + 2x - 4

Then combine like terms:

P = 12x - 18

This can be further factored to 6(2x - 3) if needed.

Since we know the expression for perimeter, we can just set it equal to 66 feet, like this:

6(2x - 3) = 66

Divide both sides by 6:

2x - 3 = 11

Add 3 to both sides:

2x = 14

Divide both sides by 2:

x = 7 feet

Which of the following points does not lie on the line y = -2x +5?
A. (4-3)
B. (-2,9)
с. (3,1)
D. (-1,7)
E. (2, 1)

Answers

Answer:

C (3, 1 )

Step-by-step explanation:

To determine if a point lies on the line, substitute the x- coordinate of the point into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line, otherwise not on line.

A (4 , - 3)

y = - 2(4) + 5 = - 8 + 5 = - 3 ← lies on line

B (- 2, 9 )

y = - 2(- 2) + 5 = 4 + 5 = 9 ← lies on line

C (3, 1 )

y = - 2(3) + 5 = - 6 + 5 = - 1 ≠ 1 ← not on line

D (- 1, 7 )

y = - 2(- 1) + 5 = 2 + 5 = 7 ← lies on line

E (2, 1 ) = - 2(2) + 5 = - 4 + 5 = 1 ← lies on line

Thus (3, 1 ) does not lie on the line → C

A triangle has three angles with the measures of (2x), (2x + 14), and (6x + 6)".
What is the measure of the smallest angle in the triangle?

Answers

Answer:

Option c : 32 degree.

Step-by-step explanation:

2x + 2x + 14 + 6x + 6 = 180 degrees

10x = 160

x = 16

2x = 16 *2 = 32 degrees

Answer:

Step-by-step explanation:

Angles in a triangle add up to 180°

You take 2x+2x+14+6x+6=180°

Collect like term and add 2x+2x+6x+14+4=180°

10x+20=180°

10x=180°-20

10x=160÷10

x=16

16*2=32

16*2+14=46

16*6+6=100

Smallest angle is 32

How many runners ran at least 3 miles?

Enter your answer in the box.

Answers

Answer:

7 runners

Step-by-step explanation:

In order to figure this question out, you need to count them up. Count up all the runners that are plotted from 3 miles on. Anything before that is under 3 miles, so it doesn't count.

After counting them up, you will find that there are 7 runners marked who ran 3 miles or more. So your answer is 7 runners.

Step-by-step explanation:

Answer:

b^8, with m = 8

Step-by-step explanation:

Apply the algebraic rule: (x^a)/(x^b) = x^(a-b)

Note: This rule is true because we can cancel all b factors that occur in both numerator and denominator.

From this rule, we know that (b^10)/(b^2) = b^(10-2)

b^(10-2) can be written b^8

Sheila is biking at a constant speed. She travels 54 meters in 9 seconds.


Part A

How many meters per second does Sheila travel?

Part B

How long in seconds would it take Sheila to travel 90 meters at this speed?

Answers

Answer:

6 m/s

15 seconds

Step-by-step explanation:

Speed = distance / time

54 / 9 = 6 m/s

Given the same speed, we can determine the time she would use to travel

time = distance / speed = 90 / 6 = 15 seconds

i need help with the volume, tsa and x please

Answers

Answer:

Volume = 42 units^2

x = 5 units

Total Surface Area = 96 units

Step-by-step explanation:

Volume

V = bh, where b = 1/2 * 3 * 4 and h = 7,

= 6 * 7 = 42 units^2

x

You can solve for this variable by using the pythagorean theorem;

a^2 + b^2 = c^2, where a = 3 and b = 4,

9 + 16 = x^2

= 25 = x^2

= x = 5 units

Total Surface Area

You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:

7 * (3 + 4 + 5) + 2(1/2*3*4)

= 7*12 + 12

= 96 units
