If the sales tax in Maple Town is 9.5%, how much would an ice cream of $4.25 cost with the tax added? Please explain.

Answers

To find the sales tax, you need to find 9.5% of 4.25

4.25*.095 = .40375

Now we need to add the sales tax to the price.

4.25 + .40375 = 4.65375
Because dollars one have 2 decimal points we should round this to 4.65

The sum of two consecutive odd integers is 32. Find the integers

Answers

consecutive odd integers is 15 and 17

They have to be both odd

15 + 17 = 32

hope this helps

Hello There!

Call the first number n:
n + n + 2 = 32
Simplify:
2n + 2 = 32
Subtract 2 from both sides:
2n + 2 - 2 = 32 - 2
Simplify:
2n = 30
Divide both sides by 2:
2n/2 = 30/2
Simplify:
n = 15
The numbers are 15 and 17.

How is dividing fractions related to multiplying

Answers

When you divide fractions, the second step is to multiply.

Hope this helps!

When dividing fractions you go through a process I call keep, change, flip. You keep the first fraction, change the division sign to a multiplication sign to a division sign and then flip the second fraction. Now, you are multiplying the first fraction by the reciprocal of your original second fraction.

the sum of twice a number and 13 is 75

Answers

Greetings!

"The sum of twice a number and 13 is 75."...

Let's translate this into an equation:
[tex]2x+13=75[/tex]
Solve for x:
Add -13 to both sides.
[tex](2x+13)+(-13)=(75)+(-13)[/tex]
Simplify.
[tex]2x=62[/tex]
Divide both sides by 2.
[tex](2x)/2=(62)/2[/tex]
Simplify.
[tex]x=31[/tex]

The variable is equal to 31.

a grandmother says her grandson is two years older than her granddaughter and that together they are at least 12 years old how old are her grandson and granddaughter

Answers

x = the granddaughter's age x + 2 = the grandson's age x + x + 2 ≥ 12 Collect like terms. 2x ≥ 12 Divide both sides by 2. x ≥ 6 years x + 2 ≥ 8 years

Grandson +gradaughter = 12

Make grandson x and granddaughter y

X=y + 2
X + y = 12

(Y + 2) + y = 12

2y + 2= 12
2y = 10
Y = 5

Jim had 3,067.48 in his checking account.He wrote a check to pay for two airplane tickets. His account now has 1,845.24. How much did each ticket cost

Answers

Each ticket is 244.648 because you subtract the money you had in the account from how much you had left. Then you multiply 1,223.24 by 2 because it says that Jim bought 2 tickets and that should get you 244.648.

Answer:

Cost of one ticket=611.12

Step-by-step explanation:

In this question we have given

Amount in account= 3067.48

After purchesing 2 airplane tickets, amount in Jim's account=1845.24

Therefore,

Cost of two tickets=[tex]3067.48-1845.24[/tex]

Cost of two tickets=1222.24

Therefore,

Cost of one ticket=[tex]\frac{1222.24}{2}[/tex]

Cost of one ticket=611.12

By how much peter is overweight he is 105 kg his aim is to lose 500 g per week if he manages this how many weeks will it be until he is 90 kg

Answers

Hello There!

105 - 90 = 15kg
500g = 1/2 kg
Peter is 15kg overweight.
15 x 2 = 30
It will take him 30 weeks for this.

Hope This Helps You!
Good Luck :)

First I would turn 500g into kg and then set up an equation like the following.

So lets convert 500g to kg. We do this by using a conversion factor.
[tex]1g = 0.001kg = 1g:0.001kg = \frac{0.001kg}{1g}[/tex]

Now that we know this conversion factor lets set it up.

[tex]500g \times \frac{0.001kg}{1g} = 0.5kg = \frac{1}{2}kg [/tex]

Ok now we know Peter wants to lose 0.5 kg or [tex]\frac{1}{2}kg[/tex] a week.

Peter wants to lose 1/2 kg a week so we use x for weeks

Lost of weight per week
[tex] \frac{1}{2}x [/tex]

Next, it tells us that Peter wants to be 90 kg. So he needs to lose 15kg.
105 - 90 = 15kg

Now we need to find out how many weeks will it be untill he is 15kg. So, Lost of weight per week = 15kg

[tex] \frac{1}{2}x = 15 [/tex]
Now solve for x in [tex] \frac{1}{2}x = 15 [/tex]

[tex] \frac{1}{2}x = 15 [/tex]
[tex] 2 \times \frac{1}{2}x = 15 \times 2[/tex]
[tex] x = 30 [/tex]
So it will take 30 weeks at 1/2kg a week to lose 15kg
