Answer: 3.88 to 219

               

Step-by-step explanation:  ok so if the data is O+ donors to B+ donors and you have to write the comparison in three different ways then you look on the chart to see that O+ is 97 & B+ is 25 then it would be 97 to 25. 97 t0 25 & 25 to 97 So I’m thinking next you have to divid  97 by 25 to get 3.88 to 219 .

I might be wrong and if I am i’m sorry.

In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.

A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40-degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y. (5 points)

Answers

60° + 70° + y° = 180°

130° + y° = 180° ~Subtract 130° from both sides

y° =50°

y=x because they are both vertical angles

x° = 50°

Answer:

40 + 50 + y = 180

90 + y = 180

90 - 90 = 0

180 - 90 = 90

y = 90

The graph shows the the number of jars that are filled by machine A and machine B. Which statement is true about the unit rates shown in the graph?
-----------------------------------------------------------------------------------------
The unit rate for machine A is greater because the slope is greater than the slope for machine B.

The unit rate for machine B is greater because the slope is less than the slope for machine A.

The unit rate for machine A is greater because the slope is less than the slope for
machine B.

The unit rate for machine B is greater because the slope is greater than the slope for machine A.

Answer:

a

Step-by-step explanation:

a presents that the a machine is better therfore i think its a.

hope this helps

The unit rate for machine [A] is greater because the slope is greater than the slope for machine B.

What is slope?

Slope of a straight line is used to define the rate of change of [y] with respect to [x].

Given are the graphs that show the the number of jars that are filled by machine A and machine B.

Slope in this case represents the number of jars filled per minute by machine A and machine B. Mathematically, we can write slope as -

m = dy/dx

Now, the ratio of [y] and [x] is equal to tanθ. So, greater the angle θ made by the line with the +x axis, greater will be its slope which in turn will represent the greater number of jars filled per minute.

It can be seen that the angle made by the straight line representing machine A makes greater angle then in the case of machine B.

So, the unit rate for machine [A] is greater.

Therefore, the unit rate for machine [A] is greater because the slope is greater than the slope for machine B.

There are 88 seats in a theater. The seating in the theater is split into 4 identical sections. Each section has 14 red seats and some blue seats.

a. Create an equation to represent this situation.

b. How many blue seats are in the theater?

c. How many red seats are in the theater?

Answers

If there's 14 red seats in each section, the total amount of red seats will be 14 times the 4 sections, which equals 56. We just subtract 56 from 88, which is equal to 32.

An equation for this would look like:

x+56=88

so:

a. x+56=88

b. 32 blue seats

c. 56 red seats

Answer:

a- (88/4) / 14 = Blue seats or red seats? maybe...

b- 56

c-56

Jake's mom is making peanut butter cookies with chocolate chips. In her first batch, she used the ratio of 2:2 for the number of ups of chocolate chips to the number of cups of peanut butter chips. In her second batch, she used a ratio of 3:1 for the number of cups of chocolate chips to the number of cups of peanut butter chips and made the same number of cookies as the first batch. Jake made the following tape diagrams for his mom to reference. If her first batch used 4 cups of peanut butter chips, how many cups of chocolate chips did Jake's mom use for the second batch?

Answers

I think it’s 6 cups of chocolate chips.

Explanation:
If in the first batch the ratio of 2 is 4 cups, that means that the ratio 1 would be 2 cups. In the second batch, the chocolate chip ratio was 3, so it would be 6 cups. I hope this helps!!!

A is your answer.

Step-by-step explanation:

Perpendicular is opposite and reciprocol of the slope. Your slope is -2 so the opposite of that is positive 2, and the reciprocol is 1/2. When you graph that you should have a point at (8,2). y=1/2x -2

Given:

3x(x - 2) + 2 and 2x² + 3x -12

If x = 7 then,

= 3(7)(7 - 2) + 2

= 21(5) + 2

= 107

= 2(7)² + 3(7) -12

= 2(49) + 21 -12

= 98 + 9

= 107

For x = 7, each expression has a value of 107.

If x = 2 then,

= 3(2)(2 - 2) + 2

= 6(0) + 2

= 2

= 2(2)² + 3(2) -12

= 2(4) + 6 -12

= 8 - 6

= 2

For x = 2, each expression has a value of 2.

These results suggests that the expressions are equivalent, but (I don't know the choices) the expressions are equivalent.

The rectangular front yard of a house has a length to width ratio of 4:5. If the perimeter of the yard is 90 meters, what is the length of the yard

A. 50 meters
B. 40 meters
C. 25 meters
D. 20 meters

Answers

Answer:

B!

Step-by-step explanation:

If the ratio is 4:5, then that means you can take the 90 and divide it by 9 (4+5) which is 10. You now know that each unit in the ratio is equal to 10 meters. If the length is 4 units, take that 4 and multiply it by 10.
