Lisa, Kelly, and Maria have $56.70. If Lisa has $23.20 and Kelly has $15.05, which equation shows how much money, n, Maria has

Answers

Answer:

38.25+n=56.70

Step-by-step explanation:

23.20+15.05+n=56.70

38.25+n=56.70

Answer:

Maria has $18.45.

Explanation:

All three of them have $56.70 all together.

So you would want to add Lisa's amount with Kelly's amount to get how much they have together.

23.20 + 15.05 = 38.25

Then you take the amount of money Lisa and Kelly has together and subtract it from the total amount of money all three of them have together to get Maria's amount.

56.70 - 38.25 = 18.45

Maria has $18.45.

Check:

Add all three of there money amounts together and if you get $56.70 you got the right answer.

23.20 + 15.05 + 18.45 = 56.70

You want to take 12 shirts, but you can only fit 3 in your suitcase. How many different ways can you choose shirts to pack?

Answers

Answer:

220 ways.

Step-by-step explanation:

This can be gotten by using the formula of combination in statistics.

The formula for combination is given below

nCr = n! / r!(n - r)!, where

r = total number of object, and

n = number of objects we're choosing from

Applying this to the question we have

12C3 = 12! / 3!( 12 - 3)!

12C3 = 12! / 3! * 9!

12C3 = 220

Therefore, we can choose to pack the shirts in 220 different ways

There are 6 children on a bus. Each child is wearing a hat. What fraction of the children on the bus are wearing a hat?

Answers

Answer:

6/6

Step-by-step explanation:

if there are 6 children, and each of them are wearing a hat, that means there are six children wearing hats, out of the six children on the bus. so the answer would be 6/6.

All 6 childrens in the bus are wearing a hat.

What is algebraic expression?

An algebraic expression in mathematics is a combination of terms both constant and variable. For example, we can write the algebraic expressions as -

2x + 3y + 5

2z + y

x + 3y

Given is that there are 6 children on a bus. Each child is wearing a hat.

Total number of children in the bus = 6

Number of children wearing a hat = 6

Fraction of children wearing a hat -

n = (Number of children wearing a hat/Total number of children in the bus)

n = 6/6

n = 1

Therefore, all 6 childrens in the bus are wearing a hat.

Answer:

B. y = 2.75x

Step-by-step explanation: Since Y represents the total cost that means that the total cost is how ever many cupcakes one were to buy. Since each cupcake is $2.75 and you are buying X amount of cupcakes, the total would be 2.75 ~multiply~ X. Thus, giving you your final answer of y=2.75x.

The zeros of a quadratic function are -7 and 3. Which of the following could be the function? Select all that apply.
A. F(x)=2x^2-8x-42
B. F(x)=5x^2+20x-105
C. F(x)=x^2+4x-21
D. F(x)=x^2-4x-21

Answers

The possible functions are

A. F(x)=2x^2-8x-42

B. F(x)=5x^2+20x-105

C. F(x)=x^2+4x-21

How to determine the possible equations?

The zeros are given as:

x = -7 and x = 3

Rewrite as:

x +7 = 0 and x - 3 = 0

Multiply both zeros

(x + 7) * (x - 3) = 0 * 0

Evaluate the product

x^2 + 7x - 3x - 21 = 0

Evaluate the like terms

x^2 + 4x - 21 = 0

Express as a function

f(x) = a(x^2 + 4x - 21)

Where a is a constant

Let a = 1, 2 and  5 (according to the values in the options)

f(x) = 1 * (x^2 + 4x - 21) = x^2 + 4x - 21 --- option (c)

f(x) = 2 * (x^2 + 4x - 21) = 2x^2 + 8x - 42 --- option (a)

f(x) = 5 * (x^2 + 4x - 21) = 5x^2 + 20x - 105 --- option (b)

Hence, the possible functions are (a), (b) and (c)
