A group of friends are going ice skating. The price of admission is $3.25. As a group, they spent $14 on refreshments. If they spent a total of $30.25 on admission and refreshments, how many friends went ice skating?

14 friends
53 friends

Answers

Answer: 5 friends

Steps:
3.25x + 14 = 30.25
3.25x = 30.25 - 14
3.25x = 16.25
x = 16.25/3.25
x = 5

Check:
3.25x + 14 = 30.25
3.25(5) + 14 = 30.25
16.25 + 14 = 30.25
30.25 = 30.25 ✅

Sides AB and BC are equal, which means angle BAC and BCA have the same measure, as stated in the base angles theorem. Angle BAC is 49 degrees, so angle BCA must also be 49 degrees. The sum of all angles in a triangle is 180 degrees, so angles BAC, BCA, and CBA will add up to 180. Write this in an equation:

BAC+BCA+CBA=180

BAC and BCA both measure 49 degrees:

49+49+CBA=180

Solve for CBA

CBA=180-49-49

CBA=82

A bag of skittles contains only red, yellow, and green colors. The respective ratios are 1:3:5 for those three colors. If there are a total of 36 skittles in the bag, how many of each skittles red, yellow, and green are in the bag?

Answers

Answer:

Red skittles = 4 skittles

Yellow skittles = 12 skittles

Green skittles = 20 skittles

Step-by-step explanation:

A bag of skittles contains only red, yellow, and green colors.

The respective ratios are 1:3:5 for those three colors.

We have

red: yellow: green

1:3:5

The sum of the proportion = 1 + 3+ 5 = 9

If there are a total of 36 skittles in the bag, how many of each skittles red, yellow, and green are in the bag?

Hence,

Number of red skittles is calculated as:

1/9 × 36 skittles

= 4 skittles

Number of yellow skittles is calculated as:

3/9 × 36 skittles

= 12 skittles

Number of green skittles is calculated as:

5/9 × 36 skittles

= 20 skittles

Therefore, the number of

Red skittles = 4 skittles

Yellow skittles = 12 skittles

Green skittles = 20 skittles

Answers

Answer:

x = 31.4

PQ = 58.8

Step-by-step explanation:

Set up a proportion:

SQ/QP = ST/PR

Substitute in the values they give you:

[tex]\frac{x-9}{x-9+x+5} = \frac{8}{21}[/tex]

[tex]\frac{x - 9}{2x - 4} = \frac{8}{21}[/tex]

[tex]21x - 189 = 16x - 32\\5x = 157\\x = 31.4[/tex]

This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8

Answer:

x = 15, PQ = 26

Step-by-step explanation:

x+13/9 = 21/x-9

x^2+4x−117=168

x^2+4x−285=0

(x−15)(x+19)=0

x=15

it cannot be a negative number so x cannot be -19

PQ= x+13

Answers

Answer:

8.93h in³

Step-by-step explanation:

The circumference of the base of the cone is 8.5pi inches. What is the volume of the cone in terms of ne? Round to the nearest hundredth. Enter

Step 1

We find the radius of the cone

Base area = 8.5 π inches

Radius = √Area/π

Radius = √8.5 π /π

Radius = √8.5

Radius of the cone = 2.9154759474 inches

Approximately = 2.92 inches

Step 2

We find the volume of the cone

= πr²h/3

Height is not given, so we find in terms of h

= π × 2.92² × h/3

= 8.9288252005h in³

Approximately = 8.93h in³

Answer:

The mean of the data set is 9.3 rounded to the nearest tenth

Step-by-step explanation:

First you add them all together: 9.9 + 10.8 + 10.8 + 6.2 + 10.8 + 7.2 = 55.7

Then you divide it by how many numbers there are which is 6 in this situation:

55.7 ÷ 6 = 9.28333333333. but if we round it to the nearest tenth we get 9.3

So the answer is 9.3

The equation of a line in slope- intercept form is

y = mx + c

Given

y - 3 = - 4(x + 2) ← distribute

y - 3 = - 4x - 8 ( add 3 to both sides )

y = - 4x - 5 ← in slope- intercept form

(b)

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

From the slope- intercept form

y = - 4x - 5 ( add 4x to both sides )

4x + y = - 5 ← in standard form

A tree 10 meters high casts a 17.3 meter shadow. Find the angle of elevation to the sun

Answers

Answer:
30.03 degrees

Step-by-step explanation:

You have labeled this diagram correctly.

The trig function that links the side opposite the angle x and the length of the shadow is the tangent function.

Here, tan x = (opposite side) / (adjacent side) = (10 m) / (17.3 m), or 0.578.

Starting from tan x = 0.578, use the inverse tangent function to find the angle, first in radians and then in degrees:

arctan 0.578 = 0.524 radians

Converting this to degrees yields 30.03 degrees. This is the angle of elevation of the sun from the horizontal, from the point where the observer is standing.

Jesse bought a car for $25,000. The car depreciates approximately 10% of its value each year. What will the car be worth in 5 years?

Answers

Answer:

Step-by-step explanation:

I got this answer by first taking the purchase price of the car and multiplying it by .10 to see what ten percent of the price was and I got $2,500. Then I took and multiplied 2,500 by 5 years and go 12,500. Then I subtracted 12,500 from the original purchase price to get $12,500. Meaning that the value of the care has decreased by half of the purchase price.

Consider a system of two linear equations in two variables. If the graphs of the equations are not the same line, is it possible for the system to have infinitely many solutions. Explain.

Answers

Answer:

Step-by-step explanation:

Solutions to systems of equations are points at which the lines of the equations intersect. Knowing this, only equations representing the same line would have infinitely many solutions because they would intersect at every one of each other's points - they're the exact same line. Therefore, if they are not the same line, they would not intersect at each and every point, and would not have infinitely many solutions.
