Answers

Answer 1

Answer:

1/6+1/3

=3+6/6×3

=9/18

=1/2

Step-by-step explanation:

Hope you find this helpful!

Answer 2

Answer: It does because 1/3 is equal to 2/6. in order to add them, they have to have the same denominator. and if you add 2/6 to 1/6, you get 3/6. 3/6 is also equal to 1/2, if you divide both sides by 3.

11. What is the perimeter of the top of a square pizza box that just manages to hold a circular pizza whose radius is 70 cm?

Answers

Multiply the radius by 2 to get the diameter: 70cm x 2 = 140cm. Then, to find the perimeter of the pizza box, multiply the radius by 4 since there are 4 sides in a square pizza box: 140cm x 4 = 560cm. Hope this helps!

Truck drivers report the mileage or the number of miles (M) traveled per gallon of gas (G) for each trip. Which driver went the farthest on one gallon of gas.

Answers

Answer:

B. Andy

Step-by-step explanation:

Kelly's mileage

This is proportional relationship, so one pair of coordinates is enough for our calculation, point (20, 50):

m = 50/20 = 2.5 gAndy's mileage

Use one pair of points from the table to calculate (15, 78.75):

m = 78.75/15 = 5.25 gRick's mileage is given:m = 4.8 g

Comparing, we see Andy's mileage is largest.

Andy will travel farther than the other drivers.

The area of a rectangular wall of a barn is 153 square feet. Its length is 8 feet longer than the width. Find the length and width of the wall of the barn.

Answers

Answer and Step-by-step explanation:

Area (A) = 153

Length (l) = 8 + w

Width (w) = w

A = lw

153 = (8 + w)(w)

153 = [tex]w^{2} + 8w[/tex]

0 =  [tex]w^{2} + 8w[/tex] - 153

 [tex]w^{2} -9w + 17w - 153[/tex]

(w - 9)(w + 17)

w = 9

w = -17

We can't have a negative length, so we only use 9.

w equals 9.

That means l equals 17     (9 + 8 = 17).

Length = 17

Width = 9

Lebron James's Free Throw % is 75%

What is the probability that he makes 6 Free Throws in a row?

Answer as a decimal rounded to 2 places.

Answers

Answer: 0.18

Step-by-step explanation:

From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:

= 75% × 75% × 75% × 75% × 75% × 75%

= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4

= 729/4096

= 0.18

Riley buys a fridge, which he can pay for using the following options. A 9 payments of $183 B $1559 up front Which option is cheaper and by how much?

Answers

Answer:

Option B is cheaper by $88.

Step-by-step explanation:

It is given that:

Option A for buying fridge,

9 payments of $183

Total cost = $1647

Option B for buying fridge

Upfront payment = $1559

Thus,

1559 < 1647

Option B is cheaper.

Difference = 1647 - 1559 = $88

Therefore,

Option B is cheaper by $88.
