At the sandwich shop, there is a sale each afternoon. A customer has a choice of
three types of bread and five different meats. Use the Fundamental Counting
Principle to determine how many combinations a customer can create ?

Answers

Answer:

15 combinations

Step-by-step explanation:

The fundamental counting principle states that if there are p ways to do one thing, and q ways to do another thing, then there are p×q ways to do both things. This means we need to multiply 3 by 5 to get the possible amount of combinations. This gets us 15. This means there are 15 combinations of bread and meat.

Batteries cost $7.85 / pack. How many packs did Ryan buy if he spent $54.95?

Answers

Answer:

7

Step-by-step explanation:

54.95 / 7.85= 7

Answer:

7

Step-by-step explanation:

ryan spent $54.95

price per pack is 7.85

in other words, 54.95 is 7.85 times the number of packs ryan bought

or

54.95=7.85x

divide by 7.85 on both sides

7=x

he bought 7 packs

check answer:

54.95= 7.85*7

54.95= 54.95

Choose an equivalent ratio. 4:9

A) 27:40
B) 27:18
C) 12:27
D) 16:27

Answers

Answer:

The answer is C.

Step-by-step explanation:

The answer is C because both numbers in 4:9 can be multiplied by the same factor (3) to get 12:27, the answer. No other choice works because they require two different number factors, not just one, which means they aren't equivalent ratios to 4:9.

Can someone help solve this?

Answers

Answer:

x = 8

y = 18

Step-by-step explanation:

First, it would be easiest to start by drawing a picture. To do so, draw two simple Isosceles triangles. Then, label their points. One having the points F, U, and N while the other has B, A, and T. Now, since both triangles are congruent, that means that F≅B, U≅A, and N≅T. Because of this knowledge, FN would be congruent to BT. So, you would be able to write that 52 = 14x - 60. By solving that, you would get the answer to x. Moving onto y, you would see that since the triangles are congruent, the interior angles are too. So, you would be able to use angles F and N to find A. By adding them to 180°, the equation would look like: 71° + 36° + (3y + 19)° = 180°. So, you would be able to find the answer to y. Hope this helped!

Two submarines began dives in the same vertical position to meet at a designated point.

If one submarine was on a course approximated by the equation x + 4y = -14 and

the other was on a course approximated by the equation x + 3y = -8, at what location would they meet?

Answers

Answer:

(10, -6)

Step-by-step explanation:

The solution of the system of the equations given would be the location that they would both meet.

Let's solve:

x + 4y = -14 ----› Eqn. 1

x + 3y = -8 -----› Eqn. 2

Subtract Eqn. 2 from Eqn. 1

y = -6

Substitute y = -6 into Eqn. 1.

x + 4y = -14 ----› Eqn. 1

x + 4(-6) = -14

x - 24 = -14

x = -14 + 24 (addition property of equality)

x = 10.

The answer is: (10, -6)

All right triangles are isosceles.
Which example proves this statement is false?

Answers

Answer:

B

Step-by-step explanation:

It is a 3-4-5 right triangle

The example Option B is False as it is a right triangle with base lengths 3 , 4 and 5

Hence , the example B is not an isosceles triangle

What Is an Isosceles Triangle?

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

The three types of Isosceles Triangles are :

Isosceles acute triangleIsosceles right triangleIsosceles obtuse triangle

Given data ,

A)

From the figure Triangle A
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

B)

From the figure Triangle B

In this triangle , all the three sides are different and it is also a right angled triangle with different lengths

So , the triangle is not isosceles

C)

From the figure Triangle C
In this Triangle , the three sides are of equal length , so it is also an isosceles triangle

So , the triangle is an isosceles triangle

D)

From the figure Triangle D
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

Hence , the example B is not an isosceles triangle and is FALSE

meters and 120 square meters. Find the height of the container? *

A)86,400m3
B)400m3
C)4m
D)6m

Answers

Answer:

D, 6m

Step-by-step explanation:

Step one:

Given data

The volume and base area of a rectangular cargo container is 720 cubic

= 720m^3

The area of the cargo container is 120 m^2

Required

We want to find the height of the container

Step two

The expression  for the volume is given as

Volume= Area* height

so,

720= 120*h

divide both sides by 120

720/120= h

h= 6 m

The height is 6m
