Incomplete question :

Here the number of ice cream sundaes isnt Given ; however, we can assume that the number of ice-cream sundae is 5

Answer:

1 / 25

Step-by-step explanation:

Given that :

Total Amount of whipped cream = 1/5 of a cup

Number of ice cream sundae = 5

The amount of whipped cream eat ice cream sundae gets is :

Total Amount of whipped cream / number of ice cream sundaes

(1 /5) ÷ 5

(1 /5) * 1 /5

= 1/25

Hence, each ice cream sundae gets 1/25 of a cup of whipped cream.

8.16 ounces  of mustard are left after she has eaten 6 hot dogs.

Two or more expressions with an Equal sign is called as Equation.

Mandy has a 10.2-ounce container of mustard.

She uses 1/30 of the mustard to put on her hot dog each time.

By given,

Mandy has a 10.2-ounce container of mustard.

Now, 1/30 of the mustard to put on her hot dog each time to 6 hot dogs, so weight of mustard used is calculated as

1/30×6×10.2=2.04 ounces

So, Amount of Mustard left after eating 6 hot dogs is,

10.2-2.04=8.16 ounces

Therefore, the required amount of mustard left after eating 6 hot dogs is 8.16 ounce.

Answer:

y = 6

x = 2

Step-by-step explanation:

rearrange the first equation in terms of x

x = (y - 2)/2

substiute x in the second equation

y = -5[(y-2)/2] +16

Now simpilify and solve for y

y = (-5y + 10)/2 +16

y = -5/2y + 5 + 16

y + 5/2y = 5 + 16

3.5y = 21

y = 6

Now substitue y in the first equation to solve for x

x = (6 - 2)/2

x = 2

You can use the fact that diagonal of a square are equal and perpendicular to each other.

The option D: Segment BD has a slope  of 3 and a length of [tex]2\sqrt{10}[/tex]

One theorem in mathematics states that:

"If diagonals of a quadrilateral are equal and perpendicular to each other, then that  quadrilateral is a square."

For ABCD to be square, we need AC and BD to be of equal length and perpendicular to each other.

Two lines are perpendicular if their slopes are negative reciprocal of each other.

[tex]Slope(AC) = \dfrac{rise}{run} = \dfrac{C_y - A_y}{C_x - A_x} = \dfrac{4-6}{8-2} = -\dfrac{1}{3}[/tex]

Thus, slope of BD needed to be negative reciprocal of -1/3 which is 3 for ABCD to be square (first needed condition)

[tex]|AC| = \sqrt{(C_y - A_y)^2 + (C_x - A_x)^2} = \sqrt{(4-8)^2 + (8-6)^2} = \sqrt{2^2 + 6^2} = \sqrt{40} = 2\sqrt{10}[/tex]

The second condition needs |BD| = |AC|.

Thus, length of BC should be [tex]2\sqrt{10}[/tex]

Thus, the sufficient condition for ABCD to be a square is:

Option D: Segment BD has a slope  of 3 and a length of [tex]2\sqrt{10}[/tex]

Answer:

i think its 10

Step-by-step explanation:

Answer:

1 to 4

Step-by-step explanation:

we know 2 feet is equal to 24 inches  and 6 inches is .5 feet so 24/6 is 4 meaning that it is 1/4 of the scale factor

Based on the length of the scale drawing and the actual length, the scale factor is 4.

This is a number that multiplies the scale drawing length to find the actual length.

It is found as:

= Actual length / Scale length

Both have to be in the same units so convert the actual length to inches:

= 2 x 12 inches per feet

= 24 inches

Scale factor is:

= 24 / 6

= 4

In conclusion, the scale factor is 4.

I'll do the first five problems to get you started.

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

Problem 1

The graph is shown below in the attached image.

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

Problem 2

The plan chosen was Public Mobile, which offered $24 per month for unlimited minutes. This plan does not depend on the number of minutes, so this is not a direct variation. It's also not a partial variation either since the cost doesn't vary (ie change) at all. The monthly cost is fixed at $24 per month.

Even at 200 minutes, this is the cheapest plan as mentioned in the other chart I posted. You can determine this by plugging x = 200 into each equation described earlier. You should find that Public Mobile still gives the cheapest rate. The graph done in problem 1 visually verifies this. The gray line y = 24 is below each of the other lines when x = 200.

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

Problem 3

The best plan is still Public Mobile when x = 1800 minutes per month.

Any x value such that x > 140 will also have Public Mobile be the best plan.

When we get to x = 140 is when this isn't the best plan and instead Bell is the better plan to go with. Note the purple line y = 0.10x+10 is below the gray line y = 24 for values x < 140. This visually shows us that Bell is cheaper compared to Public Mobile.

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

Problem 4

The plan with the greatest rate of change is Telus. This is because y = 0.35x has the largest slope of 0.35

The rate of change is the charge per minute.

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

Problem 5

If you talked for 200 minutes, then Public Mobile is the best plan. This is because the gray line y = 24 is below any other line when we have x = 200.

Answer:

sove the equation and you'll get 20

Answer:

See below.

Step-by-step explanation:

To prove these expressions are equivalent, we need to set the two expressions equal to each other in an equation and substitute 3 for g.

15(3) - 2(2(3) + 6) = 11(3) - 12

15(3) - 2(6 + 6) = 11(3) - 12

15(3) - 2(12) = 11(3) - 12

45 - 24 = 33 - 12

The volume of a box with sidelines that are 20 inches is 8000 cubic inches

Step-by-step explanation:

The volume of a box with sidelines that are 20 inches can be determined by using the formula

B = S³

Where S is the length of one side

and B is the Volume

From the question, the sidelines of the box are 20 inches. That is

S = 20 inches

From

B = S³

B = (20 inches)³

B = 20 inches × 20 inches × 20 inches

B = 8000 cubic inches

Hence, the volume of a box with sidelines that are 20 inches is 8000 cubic inches.

Using proportions, it is found that the expected value of the student's score on the test is of 3.4 points.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, there are four multiple choice questions, with five options, worth 3 points each, hence the expected score for the multiple choice questions is given by:

Em(X) = 4 x 1/5 x 3 = 12/5 = 2.4.

There are also two true-false questions(two options), worth 1 points, hence the expected score for the two true-false questions is given by:

Etf(X) = 2 x 1/2 x 1 = 1.

Then, the total expected score is given by:

E(X) = Em(X) + Etf(X) = 2.4 + 1 = 3.4.

Answer:

Step-by-step explanation:

-2 means that the y-intercept is (0, -2), so we can immediately eliminate option D. 3x means that it is a positive correlation, so left to right the line will go diagonally up, so we can eliminate option B.

Finally, we can see that 3x means that the slope is pretty steep, so we can choose C as our answer.
