A. Since the ribbons come in rolls of 15, we need groups of 15 yards. Since we are told that we have 322 yards. We have to find a way to express this number into groups of 15. To do that we can simply divide. 322 /15 = 21.466... since we can’t have one fourth of a role, we have to buy a whole one to be able to get that .4. So, Quincy needs 22 roles.

B. Twice means two times something. So all you do is multiply 322( the number of yards Quincy needs) times 2 = 644. Alice needs 644 yards of ribbon.

C. All you have to do is break 285 yards into 3 groups so: 285/3= 95. So, Elena needs 95 yards of yellow, 95 yards of red, and 95 yards of blue.

Hope this helped and pls mark as brainliest!

What would you have to do to make the line y = 2x -7 steeper on the coordinate plane?
ValentinkaMS [17]
The slope, if increased, would make the line y=2x-7 steeper. If you were to increase the y intercept, you would just move the line, not tilt it. Suggest changing it to 4x-7 = y or 8x-7= y, if you increase the slope, it'll make it steeper.

A seat on a Ferris wheel is level with the center of the wheel. The diameter of the wheel is 210 feet (ft). If the wheel
frutty [35]

Answer:

The change in the height of the seat of the Ferris wheel is a reduction in height of approximately 74.25 feet

Step-by-step explanation:

The given information are;

The position of the seat on the Ferris wheel = The center level of the wheel

The diameter of the Ferris wheel = 210 feet

The angle of rotation of the wheel = 45° counterclockwise

The height of a point on the Ferris wheel is given by the relation;

h = A·cos(b·x + c) + d

With regards to the question, we have;

h = The height of the seat of the Ferris wheel

A = The amplitude = 1/2 × The diameter of the wheel = 210/2 = 105 feet

360/b = The period

c = The phase shift = 90°

d = The mid line = 0

For a rotation of 45° counterclockwise or-45° clockwise, we have;

b·x = 45°, therefore;

h  = 105 × cos(45° + 90°) + 0 = 105 × cos(135°) + 0

h = 105 × cos(135°) ≈ -74.25 feet

Therefore, the height of the seat of the Ferris wheel reduces by 74.246 feet.

UNO [17]

According to the graph it can be inferred that the percentage of people for each transmission preference is relatively the same for left-handed and right-handed people (option D)

<h3>How to read the graph?</h3>

The graph shows two bars representing left-handed respondents and right-handed respondents. In the bars there is a blue division that represents the percentage of respondents who prefer manual transmission.

In both cases, the number of people is similar for both variables (manual and automatic) because for every 100 people surveyed, about 20 people prefer manual transmission regardless of whether they are right-handed or left-handed.
