A group of 5 friends went to the movies. A bag of popcorn costs $2.99. How much will it take cost to get one bag of popcorn for each friend

Answers

Answer:

this one is so simple add $2.99 5 times

Step-by-step explanation:

Answer:

14.95

Step-by-step explanation:

I guess you are assuming that one person is getting the popcorn for all 5 people including themselves. It's not worded the best way I've ever seen but that is the assumption I will make

So you multiply 5 * 2.99 = 14.95

Only for interest's sake, you could solve the question by multiplying by 5 * 3 dollars

5 * 3 = 15 dollars

You take off 5 cents because the actual cost is 2.99 and that is 1 cent below 3 dollars.

15.00 - 05 = 14.95  or a nickel less than 15 dollars.

A 20-sided number cube is made up of equilateral triangles. Write and solve an equation to determine the value of x on the number cube shown.

Answers

Answer:

The answer is below

Step-by-step explanation:

Triangle is a polygon with three sides and three angles. Types of triangles are equilateral, scalene, isosceles and right angled triangle. An equilateral triangle is a triangle in which all its sides are equal to each other, thereby each of its three angles measure 60°.

From the image of the 20 sided number cube, we can see that the length of each side of the equilateral triangle measures 13 mm. Therefore to find x, we use the formula:

x + 3.8 = 13

x = 13 - 3.8

x = 9.2 mm


Carlos designs the skateboard ramp shown in the diagram.
.132 in,
h
1220
Enter the height of the ramp (h), in inches. Round your answer
to the nearest whole inch.

Answers

Answer:

sin22⁰=h/132

sin22⁰×132=h

h=49.44

h=49.4inches

If length of ramp of skateboard is 132 inch and angle is 22° then height of ramp is 49 inch

What is a triangle ?

A triangle is a polygon with three edges and three vertices

Here in the given triangle

Perpendicular=h

Hypotenuse =132

angle=22°

So height of ramp can be calculated as

Sin 22°= Perpendicular/Hypotenuse

Sin 22°= h/132

h= 132[tex]\times[/tex]sin 22°

h= 132[tex]\times[/tex]0.37460659341

h=49.4480703301

[tex]h \approx49[/tex] inch

If length of ramp of skateboard is 132 inch and angle is 22° then height of ramp is 49 inch

A basketball team scored 78 points in a game. The players made 6 baskets worth 1 point each and 27 baskets worth 2 points each. The rest of the baskets made were worth 3 points each. Which equation can be used to find b, the number of baskets the players made that were worth 3 points each?​

Answers

Answer: They made 6 three point shots.

Step-by-step explanation:

Make your equation

(((6x1)+(27x2)+(3x)=78

Simplify

(6+54+3x=78)

60+3x=78

Subtract from both sides

3x=18

Divide from both sides

x=6

The basketball team scored 6 shots worth 3 points.

The number of baskets the players made that were worth 3 points each is 6 and the equation used for this is, total score = The number of 1-point baskets × 1 + The number of 2-point baskets × 2 + The number of 3-point baskets × 3.

What is the equation?

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

Total scored by the team = 78 points,

The number of 1-point baskets = 6,

The number of 2-point baskets = 27,

If b is the number of 3-point baskets, the equation can be given as,

Total score = The number of 1-point baskets × 1 + The number of 2-point baskets × 2 + The number of 3-point baskets × 3

78 = 6 × 1 + 27  × 2 + b  ×3

b = 6

Therefore, the number of baskets the players made that were worth 3 points each is 6.
