y = 6x + 2

m = 6

Answer: 48/44

Step-by-step explanation: if the area is 144 the perimeter is going to be 48. if the area is 121 the perimeter is 44. to find the perimeter you have to find the sides, since it is a square they will all be the same length. you have to find the square of the area since the formula for it is lw. then once you find the length of each side, you multiply it by 4 to find the perimeter. then to find the other question multiply the permimeter by 5.

area of square: side²

=======

side² = 121

side = √121

side = 11 cm

perimeter of square:

ii)

total distance she ran = perimeter of square * 5

distance  =  44 * 5

distance = 220 cm

Answer:

5.946

Step-by-step explanation:

The pythogorean theorem states that a^2+b^2=c^2.

We are given the hypotenuse, c, and a side length.

3.5^2+b^2=6.9^2

12.25+b^2=47.61

b^2=35.36

b=5.9464...., rounded to 5.946

Answer:

Answer:

Out of the two sums, B is the closest to the value to 1/2.

Steps for A:

Change 1/3 to 5/15

2+5/15

= 7/15

7/15 as a decimal: 0.46

0.50 - 0.46 = 0.04

Steps for B:

Change 6/7 to 18/21

Change 1/3 to 7/21

18-7/21

= 11/21

11/21 as a decimal: 0.52

0.52 - 0.50 = 0.02

The average speed, in miles per hour, of the car for the 20 miles is 37.5 mph

Average speed v = d/t where

Making t subject of the formula, we have

t = d/v

Now when the car travels 10 miles at an average speed of 30 miles per hour,

So, t = d/v

= 10/30

= 1/3 h

Also, when the car travels the next 10 miles at an average speed of 50 miles per hour,

So, t' = d'/v'

= 10/50

= 1/5 h

The total time for the 20 miles is T = t + t'

= 1/3 h + 1/5 h

= (5 + 3)/15 h

= 8/15 h

So, the average speed for the 20 miles is v = D/T where

So, v = D/T

v = 20 mi ÷ 8/15 h

v = 20 × 15 mi/8 h

v = 2.5 × 15 mi/h

v = 37.5 mph

So, the average speed, in miles per hour, of the car for the 20 miles is 37.5 mph

Answer:

x=2.0

Step-by-step explanation:

Assuming side x is tangent to the circle, we know that this is a right triangle

One of the sides is the radius. We know the radius is 1.5 units long

The other is 1.5+1 units. The length of this side is 2.5 units.

Using the pythagorean theorem...

x²+1.5²=2.5²

x²=6.25-2.25

√x²=√4

x=2

Answer:

Step-by-step explanation:

Isolate the term of e from one side of the equation.

First, you subtract by 3 from both sides.

⇒ 2e+3-3=5-3

Solve.

Subtract the numbers from left to right.

⇒ 5-3=2

Rewrite the problem down.

⇒ 2e=2

Divide by 2 from both sides.

⇒ 2e/2=2/2

Solve.

Divide the numbers from left to right.

⇒ 2/2=1

⇒ e=1

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

e = 1

Step-by-step explanation:

Subtract 3 both sides:

⇒ 2e + 3 = 5

⇒ 2e + 3 - 3 = 5 - 3

⇒ 2e = 2

Divide both sides by 2:

⇒ 2e = 2

⇒ 2e/2 = 2/2

⇒ e = 1

The pooled variance of the samples estimates the weighted variance of the samples

The pooled variance is 2952

The given parameters are:

n = 7

ss = 60

n = 7

ss = 48

The pooled variance is calculated using:

Sp = [SS1^2 *(n1 - 1) + SS2^2 *(n2 - 1)]/[(n1 - 1) + (n2 - 1)]

So, we have:

Sp = [60^2 *(7 - 1) + 48^2 *(7 - 1)]/[(7 - 1) + (7 - 1)]

Evaluate the expression

Sp = 2952

Hence, the pooled variance is 2952
