Six friends share 3/4 of a pound of roasted almonds. What fraction of a pound does each friend receive
Answers
Answer: 1/8 pounds of roasted almonds
Step-by-step explanation:
There are six friends and each of them are to receive and equal piece out of a 3/4 pound of roasted almonds.
The almonds each friend will get will therefore be the 3/4 pack divided by 6:
= 3/4 ÷ 6
= 3/4 * 1/6
= 3/24
= 1/8 pounds of roasted almonds
When dividing by a number, you can instead multiply by the inverse of that number.

A new phone costs $230 and the sales tax rate is 7%. What is the total cost of the camera after tax?
Answers
That's a question about percentage.
One way to represent percentage is using decimal number. In this way, 1 is equivalent to 100% and the other less percentages using numbers between 0 and 1.
Examples:
90% is equivalent to 0,90.5% is equivalent to 0.05. It's not 0.5 because 0.5 is equivalent to 50%.13.17% is equivalent to 0.1317.245% is equivalent to 2.45.If we want to know the percentage of a number, we should multiplacate the number by the porcentage in the decimal number form.
Examples:
55.90% of 200 is equal to: [tex]200 \times 0.5590 = 111.8[/tex]360% of 88 is equal to: [tex]88\times 3.6 = 316.8[/tex]In our problem, we have a phone with a increase of 7%. To solve that, it's important to perceive that $230 is equal to 100% and with a increase of 7%, we will pay 107%.
107% in the decimal number form is 1.07. With that information, we should multiplicate 1.07 by the original value and we will find the answer.
We know that [tex]230\times 1.07 = 246.1[/tex], therefore, the total cost of the phone after tax is $246.1.
I hope I've helped. :D

Hence, value of y = 5.5.
Answer: y = 5 ½ or y = 5.5
Step-by-step explanation:
4y - 7 = 15
Add 7 to both sides of the equation.
4y = 22
Divide both sides by 4
y = 5.5
Substitute y in the original equation.
4(5.5) - 7 = 15

Determine how much you would receive in return for a 8 month, $500 loan to a friend if you charged the 3% annual interest.
Answers
Answer:
You would receive $510.08 in return.
Step-by-step explanation:
In order to find the answer, you can use the formula to calculate the future value:
FV=PV*(1+i)^n
FV=future value
PV= present value= 500
i= interest rate=0.03/12=0.0025 per month
n= number of periods of time= 8
Now, you can replace the values in the formula:
FV=500*(1+0.0025)^8
FV=500*(1.0025)^8
FV=510.08
According to this, the answer is that you would receive $510.08 in return.

3 A garage is to be built with a skillion roof (a roof with a single
slope). The measurements are given in the diagram. Calculate
the pitch line length, to the nearest millimetre. Allow 500 mm
for each of the eaves.
Answers
Answer:
1e1e
Step-by-step explanation:
The pitch line length of the garage with the skillion roof, with the given dimensions and eave overhangs, is approximately 7.5 meters.
To calculate the pitch line length for the garage with a skillion roof, we need to consider the dimensions provided in the diagram and add the eave overhangs.
Let's assume the length of the garage is L meters, and the height from the top of the walls to the peak of the roof is H meters.
Calculate the pitch line length of the roof:
The pitch line length is the diagonal length of the triangular roof face. We can use the Pythagorean theorem to find it.
Pitch Line Length (PL) = √(L² + H²)
Add the eave overhangs:
The eave overhang is 500 mm on each side, so we need to add 1 meter (1000 mm) to the pitch line length.
Total Pitch Line Length (TPL) = PL + 1000
Now, let's calculate the pitch line length to the nearest millimeter.
For example, let's assume L = 6 meters and H = 2.5 meters.
Calculate the pitch line length (PL):
PL = √(6² + 2.5²)
PL = √(36 + 6.25)
PL = √42.25
PL = 6.5 meters
Add the eave overhangs:
TPL = 6.5 + 1
TPL = 7.5 meters

Answer:
x=9
y=5
Answer:
x = 9
y = 5
Step-by-step explanation:
3x + y = 32...(1)
3x - 2y = 17....(2)
multiplying equation (1) by 2 we get,
6x + 2y = 64...(3)
Adding eq(2) and (3) we get,
6x + 2y = 64
+ 3x - 2y = 17
----------------------
9x. = 81
therefore, x = 81/9
therefore, x = 9
substituting value of x in eq( 1)
3 * 9 + y = 32
27 + y = 32
y = 32 - 27
y = 5
