What does the word "flip" tell you to do in "Keep, Change, Flip" for dividing fractions?
A
change the places of the numbers in the numerator and the denominator for the first fraction
B
change the places of the numbers in the numerator and the denominator for the second fraction
C
change the places of the numbers in the numerator and the denominator for both fractions
D
change the division sign between the fractions

Answers

Answer: It is C.

Step-by-step explanation:

When you are dividing fractions, you should always flip the numerator and denominators for the second fraction. After flipping the second fraction, you should multiply the first fraction and the second fraction together.

Example: 1/3 divided by 2/5= 1/3 x 5/2= 5/6

A packaging firm has been hired to create a box for baby blocks. The firm was hired because it could save money by creating a box using the least amount of material. the packaging firm knows that the volume of the box must be 18cm^3.

A. What are the possible dimensions for the box if the volume must be18 cm3?

B . Which set of dimensions should the package firm choose in order to use the least amount of material? Explain Please show work

Answers

Answer:

A. 3cm by 3cm by 2cm or 6cm by 3cm by 1cm

B. 3cm by 3cm by 2cm

Step-by-step explanation:

POSSIBLE DEMENSIONS

3cm by 3cm by 2cm = 18cm^3

6cm by 3cm by 1cm = 18cm^3

LEAST AMOUNT OF MATERIAL

3 by 3 by 2 would mean 6cm squared of material per side

6 + 6 + 6 + 6 + 6 + 6 = 6 times 6 = 36

Total : 6 sides = 36cm^2 used

6 by 3 by 1 would mean 2 sides of 6cm^2, 2 sides of 3cm^2 and 2 sides of 18cm^2

18 + (6 + 6) + (3 + 3) =

18 + 12 + 9 =

30 + 9 = 39

Total: 39cm^2

expand the terms we get:

x^3 + 4x^2 - x^3 + 3y^2 + 12 - 4 +30y - 2y^2 + 3x

bring all like terms together we get:

A triangle is formed by intersecting lines.

What is the measure of angle x?

Answers

The sum of all angles of a triangle = 180.
So 180-90 (right angle) - 51 (other known angle) = 39
the measure of angle x would be 39°
triangles only go up to 180° and that triangle already has a 90° right angle and a 51° acute angle. so the answer is 39°

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.
​​​​​​

1. The slope of the linear model is 1.5. What does this mean in terms of the maximum noise level and the number of people?

2. A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.

3. What is the -intercept of the linear model given? What does it mean in the context of the problem? Is this reasonable? Explain your reasoning.
