Benjamin bought a 3-pound bag of flour for $6.95. What is the unit price per ounce of flour? (1 pound = 16 ounces)
Answer:
Step-by-step explanation:
Since there are 16 oz in 1 lb, to find the amount in 3 lbs, you would just multiply it by 3
16 · 3 = 48
to find the price you divide the total price by number of oz.
6.95 ÷ 48 ≈ 0.1448

Jamian bought a total of 35 bagels and donuts for a morning meeting. He paid a total of
$25.75. Each donut cost $0.55 and each bagel cost $1.20. The system of equations
b + d = 35
1.200 + 0.55d = 25.75 models this situation, where b is the number of bagels and d
is the number of donuts. How many of each did Jamian buy?
{ 1.200
Jamian bought
bagels and
donuts.
Answer:
Number of bagels = 10
Number of donuts = 25
Step-by-step explanation:
Let Number of bagels = b
Number of donuts = d
As given,
Each donut cost $0.55 and each bagel cost $1.20
⇒ Cost of d donuts = $0.55d
Cost of b bagels = $1.20b
Also given,
Jamian bought a total of 35 bagels and donuts
⇒ b + d = 35 ........(1)
Also,
He paid a total of $25.75.
⇒ 1.20b + 0.55d = 25.75 .........(2)
Now,
Multiply equation (1) by 1.20 , we get
1.20( b + d = 35 )
⇒1.20b + 1.20d = 42 ..........(3)
Now,
Subtract equation (2) from equation (3), we get
1.20b + 1.20d - ( 1.20b + 0.55d ) = 42 - 25.75
⇒1.20b + 1.20d - 1.20b - 0.55d = 16.25
⇒0.65d = 16.25
⇒d = [tex]\frac{16.25}{0.65}[/tex] = 25
⇒d = 25
Put the value of d in equation (1) , we get
b + d = 35
⇒b + 25 = 35
⇒b = 35 - 25 = 10
⇒b = 10
∴ we get
Number of bagels = b = 10
Number of donuts = d = 25

Ranbir bought a rectangular field of area 24000 square metres and width 120 m. He wants to fence it with two rounds of wire. Find the length of wire that will be required to fence the field.
Answer:
640 metres
Step-by-step explanation:
Area of a rectangular field = 24000 square metres
Width of a rectangular field = 120 metre
Also,
Area of a rectangular field = Length × Breadth
24000 = Length × 120
Length = [tex]\frac{24000}{120}=200[/tex] metre
Length of wire required to fence the field = Perimeter of the rectangular field
= 2 (length + width)
= 2 (200 + 120)
= 2 (320)
= 640 metres
What is the fewest number of consecutive primes, starting with 2, that when summed produce a number divisible by 7?
Answer:
5
Step-by-step explanation:
The consecutive primes starting from 2 are
2, 3, 5, 7, 11
Summing gives 2 + 3 + 5 + 7 + 11 = 28
and 28 is divisible by 7
Thus the required number of primes is 5
The fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.
To determine what is the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7, the following calculation must be performed:
2 + 3 = 5 2 + 3 + 5 = 10 2 + 3 + 5 + 7 = 17 2 + 3 + 5 + 7 + 11 = 28 28/7 = 4
Therefore, the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.

13. L'Shonda purchased a container of juice that contains 200 calories. The label says that 40% of the calories are from carbohydrates. How many calories are from carbohydrates?
Answer:
80
Step-by-step explanation:
So I here's my thought process on this:
200 divided by 2 is 100
100 - 40% is 60, leaving 40 behind.
So double that and it would be:
200 - 40% is 120
200 - 120 = 80
80% is the answer.

Calculate
Given
14x-13=7x+29
Add 13 on both sides
14x-13+13=7x+29+13
14x=7x+42
Subtract 7x on both sides
14x-7x=7x+42-7x
7x=42
Divide 7 on both sides
7x/7=42/7
