Answer:

1 and 7/12 hours

Step-by-step explanation:

2 and 1/3 is the whole. You need to subtract 3/4. To bring both of these to the same denominator, multiply each fraction by the others denominator. That means 1/3 is now 4/12 and 3/4 is now 9/12. They can now be subtracted. 2 and 4/12 - 9/12 = 1 and 7/12.

Find the value of x in the figure

Answers

Answer:

x = 100

Step-by-step explanation:

I know that the total is 180 so with that in mind this is what i did to get the answer.

180 - 57 = 123

123 - 23 = 100

Double check your work

100 + 23 = 123

then 123 + 57 = 180

your answer is 100:)

hope this helped!

Answer:

100 because, the bottom line is 180 degrees so do 180-57 which would equal 123 then do 123-23 and there's your answer 100.

Answers

Answer:

The third graph is correct

Step-by-step explanation:

Hiiii,

Since the sign is < and doesn't have a line underneath (or equal to), it means we have an open circle. We also know that the line has to go to the left because all the values that go to the left make the inequality true. If they go to the right, it won't be true because the value will be greater than 21 and we need it to be less than 21.

Hope this helps :)

answer is c because the shape is reflected across the x axis and shifted 6 units left you can tell it’s shifted left because if you stuck with on point from the original it goes 6units left and lands on the new shape

The answer is c. Because if you flip it over x axis then it is in the same direction as the other shape which means as long as you move it over 6 units it will be at the exact same position as the other shape.

Answers

Answer:

50 stuffed animals and 22 mystery boxes.

Step-by-step explanation:

Firstly, we assign variables.

Let the number of stuffed animals be x and the number of mystery boxes is y

The probability of selecting a stuffed animal is x/72 while the probability is selecting a mystery box is y/72

Now, since the total probability can be 1:

a cone has a height of 11 millimeters and a radius of 5 millimeters. what is its volume?

Answers

Answer:

287.83 cubic mm

Step-by-step explanation:

Given,

Height of the cone = 11 mm

Radius of the cone = 5 mm

Therefore, volume of the cone

[tex] = \frac{1}{3} \pi {r}^{2} h[/tex]

[tex] = \frac{1}{3} \times 3.14 \times 5 \times 5 \times 11[/tex]

= 287.83 cubic mm (approx. ) (Ans)

If the cone has a height of 11milimeeter the answer is 226.26
