A pair of snow boots at an equipment store in Big Bear that originally cost $80 is on sale for $56. What is the rate of discount?

Answers

Divide the sale price by the original price:

56 / 89 = 0.7

Multiply by 100:

0.7 x 100 = 70%

The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)

C. Length of the base
O D. Volume of the base

Answers

Answer:

A.Area of the base

Step-by-step explanation:

these is obtained by multiplying the length and width of the base to get the area of the base

The variable B in the Formula is area of Base.

What is Volume?

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Pyramid volumes are measured by how much space they take up or by how many unit cubes can fit inside of them. A pyramid is a polyhedron because it has polygonal faces.

As, Volume of pyramid = (1/3) (Bh), where

B = Area of the base of the pyramid

h = Height of the pyramid.

So, B in the Formula is area of Base.

If Sue worked 7 1/4 hours on Monday, 3 hours on Tuesday, 6 3/4 hours on Wednesday, 8 hours on Thursday, and 5 hours on Friday, calculate her weekly wage at $4.10 per hour

Answers

Answer:

$123

Step-by-step explanation:

Let's find the total amount of hours Sue worked. To do so, we'll do 7.25 + 3 + 6.75 + 8 + 5 = 30 total hours. Now, we'll multiply 4.1 by 30 because she receives $4.10 for every hour. 4.1 * 30 = $123. Hope this helps!

$123 if u add all the hours together u end up getting 30. 30 multiplied by 4.1 is 123

they said that it has to be the same group as S and T

the only numbers that are in the same groups is 2 and 4

the fraction is then 2/10

which is .2

What is probability?

The probability of an event occurring is defined by probability.

Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

Do not take underestimate probability it has several uses in daily life whether forecasts and like that.

In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.

Given that the S = {2, 4, 6, 8, 10 and T = {1, 2, 3, 4, 5)

Now there are a total of 10 numbers. The common number among S and T are 2 and 4  only so

Plug the ordered pair (2,5) into the given equation, if it makes the equation true, then it is a solution.

Step-by-step explanation:

y = 2x + 3

substituting :  5 = 2(2) + 3

                       5 = 4 + 3

                        5 = 7, this is false, therefore (2,5) is NOT a solution

Answer:

A linear equation's solution would be a coordinate when the value of x and y satisfies the equation.

For Example:

[tex](1,7)[/tex] will be a solution to the equation [tex]y=3x+4[/tex], because if you replace x and y with one and seven it satisfies the equation.

[tex]y=3x+4\\y=7 \\x=1\\\text {Solve: }\\7=3(1)+4\\\rightarrow3*1=3\\7=3+4\\\boxed {7=7}[/tex]

[tex](1,7)[/tex] also lies on the equation's line.

(please show all your work Let, So, Equation and Solution and Therefore Statement)

Answers

Answer:

It'll take 7 hours for the car B to cath up to A

Step-by-step explanation:

In order to solve this problem we can write the equation from the distance of each car. Assuming that t = 0 happens when the second car leaves Toronto. When the second car leaves Toronto, the first one is on the road for two hours already, thefeore it travelled a total of:

distance = speed*time = 70*2 = 140

We have:

Car A:

x(t) = 70*t + 140

Car B:

x(t) = 90*t

We now need to find the value of "t" that makes x(t) the same for both cars:

90*t = 70*t + 140

20*t = 140

t = 140 / 20 = 7 h

josh allowance is m cents per week. Represent the number of dollars he gets in a year.
a) 3m/25
b) 1200m
c) 13m/25
d) 25m/13

Answers

Answer:

The number of $ Josh receives in a year should be 13m / 25

Step-by-step explanation:

This is quite a simple a question.

Consider how many weeks there are in a year. Well there are about 52 weeks, you can say. Knowing that, you could apply the following conversion factor -

[tex]\frac{52 ( weeks ) }{ 1 ( year )}[/tex] ... at the same time we have to consider how many cents there are in a dollar. There are 100 cents, giving us the conversion factor [tex]\frac{1 ( dollar )}{100 ( cents )}[/tex]. Therefore, Josh's allowance should be, after 1 year -

m [tex]*[/tex] [tex]\frac{52}{1}[/tex] [tex]*[/tex] [tex]\frac{1}{100}[/tex]

= [tex]\frac{52m}{100}[/tex] - Which, simplified, = [tex]\frac{13m}{25}[/tex].

Our solution here is option c, rather option d.

The number of dollars he gets in a year is 13m/25 option (c) is correct if josh allowance is m cents per week.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

Josh's allowance is m cents per week.

As we know,

Total number of weeks in a year = 52 weeks

In 1 dollar there are 100 cents

josh's allowance is m cents per week

The number of dollars he gets in a year = (52/100)m

After simplification:

The number of dollars he gets in a year = 13m/25

Thus, the number of dollars he gets in a year is 13m/25 option (c) is correct if josh allowance is m cents per week.
