mandle is making 15 cups of fruit salad . what ration of grapes to blueberries should she use?

Answers

Answer:

12:3

Step-by-step explanation:

The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.

The function represented by the table is

y = 0.25x

Then, as Mandie is making 15 glasses of fruit salad, we have:

y + x = 15

We have two equations and two unknowns that we must solve.

y = 0.25x

y + x = 15

Resolving

For x:

0.25x + x = 15

1.25x = 15

x = 15 / 1.25 = 12

For y:

y = 0.25x = 0.25 (12) = 3

Answer

The ratio of grapes to blueberries she should use is 12: 3

Answer:

x = 3

Step-by-step explanation:

(13x - 2) and (12x + 1) are vertically opposite angles and are congruent , so

13x - 2 = 12x + 1 ( subtract 12x from both sides )

x - 2 = 1 ( add 2 to both sides )

Which best describes the graph of the function f(x) = 4(1.5)x?
​

Answers

In the question "Which best describes the graph of the function f(x) = 4(1.5)^x?" The correct answer is "The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5." (option B) Because when x = 0, f(0) = 4(1.5)^0 = 4(1) = 4. Thus the graph passes through (0, 4). Also for every increase of 1 in the x-values, the y-values increase by a factor of 1.5 i.e. f(0) = 4(1.5)^0 f(1) = 4(1.5)^1 f(x) = 4(1.5)^2 etc

Maggie makes some fruit punch. She mixes 2 1/2 quarts of grape juice with 1 1/2 quarts of orange juice. One quart of grape juice costs $1 less than one quart of orange juice. She finds that the total of making the fruit punch is $12.50. Calculate the cost of each quart of grape juice and each quart of orange juice.

Answers

Grape juice(G) is 1$ less than Orange juice (O)
G = O - 1

Orange juice and Grape juice is 12.50 total.
O+G=12.50
or
O+O-1=12.50 since G=O-1

Solve
2O-1=12.50
2O=13.50
o=6.75

The cost is 6.75$ per quart of orange juice

Grape is just 1$ less than that. So 6.75-1 = 5.75. Grape juice costs 5.75 per quart.

We have 2 and 1/2 quarts of grape juice and 1 and 1/2 quarts of orange juice. Or 5/2 and 3/2 to make it easier.

Multiply the amount of quarts with the costs per quart.
5/2*5.75= 14.375

3/2*6.75=10.125

Total costs is
14.375+10.125=$24.5

The answer is it costs about $10.13 for orange and $14.38 for grape.

Using the line of random numbers to run one simulation, the proportion of students that tried out for a sport is .4

Given that 40% of students tried out for a sport in a school

The survey is an SRS of 20 students.

Hence, to find the proportion of students that tried out for a sport with the use of a line of random numbers would be:

Point A is (5, 7).
Point B is (x, y).
The midpoint of AB is (17,-4).
What are the coordinates of B?
A. (22,-9)
B.(12,-11)
C. (29.-15)
D. (8.5,-2)

Answers

The coordinate of point B is at (29, -15): Option C is correct.

The formula for calculating the midpoint of two points is expressed as:

[tex]M(x, y) = {\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2}}[/tex]

Given the coordinate points

A is (5, 7).

B is (x, y).

M is (17, -4)

Substituting into the formula to get x and y

17 = 5+x/2

5+x = 34

x = 34 - 5

x = 29

Get the value of y. Similarly;

-4 = 7+y/2

-8 = 7+y

y = -8-7

y = -15

Hence the coordinate of point B is at (29, -15)

Sarah and Emily ran a 324m race. If Sarah ran it in 61.3 seconds and Emily ran it in 60.4 seconds, how much faster was Emily than Sarah? Round to the nearest hundredth and give your answer in meters per second.

Answers

Answer:  0.08 meters per second

=======================================================

Work Shown:

Distance = rate*time

rate = distance/time

----------------

For Sarah, she runs 324 m in 61.3 seconds. Her speed is:

rate = distance/time

rate = (324 m)/(61.3 sec)

rate = (324/61.3) meters per second

rate = 5.28548 meters per second approximately

----------------

Repeat the same set of steps for Emily

rate = distance/time

rate = (324 m)/(60.4 sec)

rate = (324/60.4) meters per second

rate = 5.36423 meters per second approximately

----------------

The last thing to do is subtract the results we got

5.36423 - 5.28548 = 0.07875

This then rounds to 0.08 meters per second when rounding to two decimal places.

Determine the measure of the indicated
exterior angle in the diagram.

Answers

Answer: 110 degrees

Triangle sum theory tells us that all the internal angles are equal to 180.

Meaning, we can solve 2x+3x+3x+4=180 for x

x=22

Then solve for 3x+4, which equals 70.

Last step, take 70 from 180 to find the external angle!

110 :)

Answer:

Exterior angle is equal to 110

Step-by-step explanation:

So to find the exterior angle, you must find the interior angle first.

You know that all 3 angles within the triangle must equal to 180 degrees, so what we can do is set up this equation to reflect that statement:

2x+3x+(3x+4) = 180

Group like terms:

8x+4=180

Solve for x:

8x = 176

x = 22

We can double check to see this matches up with all of the other angles inside:

2x = 44

3x = 66

3x+4 = 70

44 + 66 + 70 = 180

We also know that a straight line is 180 degrees

So, ? = 180 - 70

? = 110 degrees
