Answer:

true

Step-by-step explanation:

Answer 2

Answer:

True

Step-by-step explanation:

Start by narrowing the equasions down, add all the numbers together:

1s + 1s + 1s + 1s = 4s

4s = 4s

Both equasions are equivelent to 4s, so the answer would be True.

If you had trouble understanding that, here is another way:

First lets set a control number for s, like 3. then we are going to place the control into the equasion:

1(3) + 1(3) + 1(3) + 1(3)

4(3)

Now solve:

1(3) + 1(3) + 1(3) + 1(3) = 12

4(3) = 12

Both equasions are equivelent to 12, so the answer would be True, they are equivelent.

Answers

Answer:

it is 3 times larger

I know because i found the area of Peter and Jill's net and divided the area of Jills net by peters net

Step-by-step explanation:

Area = height x width

Area pf soccer net in Peter's back yard = 51/2 x 4 = 22 feet^2

Area of jill's soccer net = 51/2 x 16 = 66 feet squre

difference in area = 66/22 = 3

The numbers of cookies in a shipment of bags are normally distributed, with a mean of 64
and a standard deviation of 4. What percent of bags of cookies will contain between 60
and 68 cookies?

Answers

Answer:

68% i think yeah?

The percent of bags of cookies will contain between 60 and 68 cookies is 68.29%.

What is standard deviation?

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

[tex]\mu[/tex]= 64, [tex]\sigma[/tex]= 4,

[tex]Z_1[/tex]= [tex]X_1[/tex] - [tex]\mu[/tex]/ [tex]\sigma[/tex]

= 60-64/4

= -1

again,

[tex]Z_2[/tex]= [tex]X_2[/tex] - [tex]\mu[/tex]/ [tex]\sigma[/tex]

= 68-64/4

= 1

Thus, P( 60<X<68)

= p(-1<Z<1)

= 0.6829

= 68.29%

Step-by-step explanation:

A to B - just count up the numbers, it's 10

B to C - just count up the numbers, it's 12

A to C - Now this is a right triangle, so use the Pythagorean theorem(10^2 + 12^2 = 244, and take the square root of that, which is 15.62 and round to 15.6

And just add them together 10+12+15.6 to get 37.6

80 + 8x + 10x + x² = 160

combine like terms:

x² + 18x - 80 = 0

factor:

(x - 3.69)(x + 21.69) = 0

x = 3.69

Answer:

x = 3.69 feet

11.69 x 13.69 feet

new area = (8 x 10) x 2 = 160

(8 + x)(10 + x) = 160

The area of the living room carpet was s 262.5 square feet. If the width of the room is 21 feet, then what is the length.

Please help, I’m taking an online test, I need it, quick. :)

(15 points!)

Answers

The length would be 12.5 feet.

A rectangle’s area is calculated with the formula:

A = L * W

To find the length, all we have to do is divide the area (A) by the width (W).

We get the equation:

262.5/21 = L

262.5/21 = 12

L = 12

What is the solution to this system? Solve by substitution. y= 4x +3 and 2x - 3y = 21

Answers

Answer:

x= -3

y= -9

Step-by-step explanation:

Y-4X =3 ; 2x-3y=21

Y= 3+ 4x

2x -3( 3+4x)= 21

2x- 9- 12x= 21

-10x -9= 21

-10x -9+9= 21+9

-10x = 30

X= 30/-10= -3

Y= 3+4x = 3+ 4* (-3)= 3-12= -9

The angle measurements found in an equilateral triangle are 60°, 60°, 60°

What is an Equilateral Triangle?

An equilateral triangle is an angle that has equal angles and equal sides. It implies that all the sides of the angle contain the same length.

We can also say that an equilateral triangle is also equiangular since it has equal angles. If we recall, we know that the sum of angles in a triangle is 180°.

For a triangle with equal sides, it implies that each length will possess;

= 180°/3

= 60° each.

combine like terms, 1+6 is 7 and 2t+4t is 6t. so 6t+7=55. get the t by itself by subtracting 7 from both sides. 6t=48, divide by 6. t=8

Answer:

I'm assuming you are trying to get t alone so t=8

George and carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 350 miles in total, and they biked 80 kilometers more than they were bused.

Answers

Complete question − How many kilometres did they travel by bus and by bicycle.

Answer:George and carmen traveled by bus in 135km and by bikein 215km

Step-by-step explanation:

Total Miles traveled = 350 miles

Let Number of kilometres they traveled with bus = x

and Let Number of kilometres they traveled with bike = x + 80

so that the total distance traveled with bus and bike be expressed as

x + x + 80 = 350 miles

2x + 80 = 350 miles

2x = 350 − 80

2x =270

x=135

George and Carmen traveled by bus in 135km

and by bicycle=x + 80 = 135 km + 80 =215km
