c = grocery store charges

Tax is 8% added to the charges.

Which expression shows the total charges with tax?

A. 1.8c
B. 1.08c

Answers

Answer 1
B because it is in the 10ths place
Answer 2

The total charge with tax will be 1.08c.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Grocery store charges = c

And, Tax is 8% added to the charges.

Now,

Since, Tax is 8% added to the charges.

Hence, The total charge with tax = c + 8% of c

                                                   = c + 8/100 × c

                                                   = c + 0.08c

                                                   = 1.08c

Thus, The total charge with tax = 1.08c.

Two angels are supplementary. The measure of the large angle is four more than three times the measure of the small angle. Find the measure of both angles.

Answers

Answer:

The measure of the two supplementary angles is

Small angle = x = 44°

Large angle = y = 136

Step-by-step explanation:

Supplementary angles are two angles whose measures add up to 180° .

Let

Small angle = x

Large angle = y

x + y = 180°.... Equation 1

The measure of the large angle is four more than three times the measure of the small angle

Hence: y = 4 + 3x

We substitute 4 + 3x for y in Equation 1

x + 4 + 3x = 180°

4x + 4 = 180°

4x = 180° - 4

4x = 176

x = 176/4

x = 44°

Solve for y

y = 4 + 3x

y = 4 + 3(44)

y = 4 + 132

y = 136°

Therefore, the measure of the two supplementary angles is

Small angle = x = 44°

Large angle = y = 136

Expand and simplify

Answers

Answer:

5-3x

Step-by-step explanation:

To expand this, we start with the distribution of -3 into the parentheses containing x+2

This leaves us with

11-3x-6

From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6

We combine them by subtracting 11-6 to get 5.

This leaves us with our answer,

11-6-3x

5-3x

An alternate way of writing this would be

-3x+5

But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now

A bouncy castle can be hired for party's. The cost is given by Cost=£4.70 times number of children + £86. What is the cost of the bouncy castle for 13 children. At a different party, the cost of hiring the bouncy castle was £165.90.How many children went to the party.

Answers

Answer:

A. £147.10

B. 17 children

Step-by-step explanation:

Let

Number of children = x

Cost of hiring a bouncy castle = £4.70 * x + £86

What is the cost of the bouncy castle for 13 children

Cost of hiring a bouncy castle = £4.70 * 13 + £86

= £61.1 + £86

= £147.10

How many children went to the party when cost of hiring bouncy castle = £165.90

Cost of hiring a bouncy castle = £4.70 * x + £86

£165.90 = £4.70 * x + £86

165.90 = 4.70x + 86

165.90 - 86 = 4.70x

79.9 = 4.70x

x = 79.9/4.70

= 17

x = 17 children

The number of fish in a lake decreased by 25% between last year and this year. This year there are 45 fish in the lake. What was the population of last year

Answers

Answer:

The population of last year was 60.

Step-by-step explanation:

From the information given, as you know that the number of fish in a lake decreased by 25% between last year and this year, the amount of fish this year represents 75% of last year's population as: 100%-25%=75%. With that, you can use a rule of three to find last year's population tha would represent 100% given that 75% is equal to 45 fish.

75%   →  45

100%  →   x

x=(100*45)/75= 60

According to this, the answer is that the population of last year was 60.
