Question

Aaron bought a large basket of 59 apples for $22.95. He also bought a small basket of 18 apples for 8.95. Which amount is the closest estimate of the cost per apple?

Solution 1

22.95+8.95 = 31.90

31.90/77 = .41

So, it'd be .40 if you were rounding.

31.90/77 = .41

So, it'd be .40 if you were rounding.

Question

Julie counted 25 players on a visiting soccer team. The actual number of players on the visiting soccer team was 27. What is the percent error in Julie’s measurement? If necessary, round to the nearest percent.

Solution 1

I did 2/27 which equals 0.074

So its basically 74

So to make it a percentage we need to move it 2 spaces=

7.4%

So its basically 74

So to make it a percentage we need to move it 2 spaces=

7.4%

Question

-1 ≥ -8; Multiply both sides by -2

Solution 1

Question

What is the approximate circumference of a circle with a radius of 42.1 km? A. 5565.4 km
B. 1391.3 km
C. 264.4 km
D. 132.2 km

Solution 1

C.264.4 that should answer your question

Solution 2

Circumference of circle = 2*pi*r

= 2*22/7*42.1

= 264.4 km

Therefore, the circumference of the circle is**264.4 km**

= 2*22/7*42.1

= 264.4 km

Therefore, the circumference of the circle is

Question

Write a story problem about 40 apples and 17 pears

Solution 1

There were 40 apples with 17 pears that died.

Question

Claire’s mother is 4 years more than twice Claire’s age. The sum of their ages is 58 years.

Solution 1

Claire's age = x

claire's mothers age = 2x+4 ( 4 more than twice claire's age)

sum is addition

x + 2x+4 = 58

add like terms ( x +2x = 3x)

3x +4 = 58

subtract 4 from each side:

3x = 54

divide both sides by 3

x = 54 /3

x = 18

Claire is 18 years old

Claire's mother is 2*18 = 36 +4 = 40 years old

claire's mothers age = 2x+4 ( 4 more than twice claire's age)

sum is addition

x + 2x+4 = 58

add like terms ( x +2x = 3x)

3x +4 = 58

subtract 4 from each side:

3x = 54

divide both sides by 3

x = 54 /3

x = 18

Claire is 18 years old

Claire's mother is 2*18 = 36 +4 = 40 years old

Solution 2

Let x = Claire's age

Claire’s mother is 4 years more than twice Claire’s age = 2x + 4

The sum of their ages is 58 years:

x + 2x + 4 = 58

3x + 4 = 58

3x = 54

x = 18

Claire's age = 18

Claire’s mother = 2(18)+4 = 36 + 4 = 40

Claire’s mother is 4 years more than twice Claire’s age = 2x + 4

The sum of their ages is 58 years:

x + 2x + 4 = 58

3x + 4 = 58

3x = 54

x = 18

Claire's age = 18

Claire’s mother = 2(18)+4 = 36 + 4 = 40

Question

What two prime numbers equal 85 when added together?

Solution 1

I started out trying to subtract a prime number from 85, and then

see whether I had a prime number remaining. I did this several

times, before I slapped myself upside the head.

-- 85 is an odd number.

-- To get an odd-number for a sum, you have to add one odd number

to one even number ... there's no other way.

-- So one of the prime numbers we're looking for must be

an even number.

-- The ONLY even number that's a prime number is ' 2 '.

So it must be one of them.

-- Subtract 2 from 85, and you have 83 left.

Is 83 a prime number ? Yes.

-- So the two numbers are

If 83 were not a prime number, this wouldn't work, and I would have said

"There is no such pair of numbers.". That means it doesn't necessarily work

for every odd number.

Examples:

75 ===> 2 and 73 . \

55 ===> 2 and 53 . \

45 ===> 2 and 43 . \

Both primes. It works.

65 ===> 2 and 63 . 63 is not a prime. \

35 ===> 2 and 33 . 33 in not a prime. \

It doesn't work.

Question

A flagpole casts a showdown 15 feet long the 6 foot tall man casts a shadow 4 feet long how tall is the flag pole

Solution 1

Set it up as a ratio:

mans shadow over mans height (4/6 ) equals flag pole shadow over flag pole height (15/x)

set them to equal each other:

4/6 = 15/x

cross multiply: 4*x =4x, 15*6 = 90

so you have 4x = 90

now divide both sides by 5 to solve for x, which is the height of the flag pole:

x = 90 / 4 = 22.5 feet tall

mans shadow over mans height (4/6 ) equals flag pole shadow over flag pole height (15/x)

set them to equal each other:

4/6 = 15/x

cross multiply: 4*x =4x, 15*6 = 90

so you have 4x = 90

now divide both sides by 5 to solve for x, which is the height of the flag pole:

x = 90 / 4 = 22.5 feet tall

Question

she brought the cameras for $65 each and included a 60% markup to get the selling price ,what was the selling price for one camera?

Solution 1

60% of 65=

0.6*65=36

add it into a sum with 65

39+65= 104

**This means each camera is worth $104**

Hope I helped

0.6*65=36

add it into a sum with 65

39+65= 104

Hope I helped

Solution 2

39 I think

how many cameras did she buy?

opps I forgot to add 39 to 65 for a total of 104

SORRY

how many cameras did she buy?

opps I forgot to add 39 to 65 for a total of 104
