For this case we can make the following rule of three:

8 lemons --------> 80 ounces of lemonade

38 lemons ------> x

Clearing x we have:

x = (38/8) * (80)

x = 380 ounces

We observed that:

380 <448

Therefore, more lemons are needed.

**Answer:**

**Yes, Tanisha needs more lemons**

8 lemons --------> 80 ounces of lemonade

38 lemons ------> x

Clearing x we have:

x = (38/8) * (80)

x = 380 ounces

We observed that:

380 <448

Therefore, more lemons are needed.

Question

PLS HELP! Tanisha is planning a party. She will serve hamburgers, potato salad, strawberry shortcake, and lemonade. Including Tanisha, 28 people will be at the party. Tanisha expects that each person will drink two 8−ounce glasses of lemonade at the party, and makes 448 ounces of lemonade. Tanisha's mother buys 38 lemons. They know it takes 8 lemons to make 80 ounces of lemonade. Does Tanisha need more lemons?

Solution 1

Shee needs 448 ounces of lemonade.

448 ÷ 80 =5.8

⇒ There are 5.6 80-ounce of lemonade.

80 ounces of lemonade needed 8 lemons.

448 ounces of lemonade needed 8 x 5.6 = 44.8 lemons.

Tanisha has 38 lemons.

She does not have enough lemons.

She needs 44.8 - 38 = 7 more lemons.

**Answer: ****Tanisha needs more lemons. She needs 7 more.**

448 ÷ 80 =5.8

⇒ There are 5.6 80-ounce of lemonade.

80 ounces of lemonade needed 8 lemons.

448 ounces of lemonade needed 8 x 5.6 = 44.8 lemons.

Tanisha has 38 lemons.

She does not have enough lemons.

She needs 44.8 - 38 = 7 more lemons.

Solution 2

**Answer: 7 more lemons**

**Step-by-step explanation:**

Since she needs 448 ounces of lemonade you have to divide which is 5.6 . As a result there are 5.6 80 ounces of lemonade. 80 ounces needs 8 lemons. 448 ounces of lemonade are needed 8 x 5.6 = 44.8 lemons. Tanisha only has 38 lemons, which isn't enough. 44.8 - 38 = is about 7 more lemons.

Question

Please help me -3x-3x=-24

Solution 1

-3x - 3x = -24

Combine like terms:

- 6x = -24

Divide both side by -6:

x = 4

**Answer: x = 4**

Combine like terms:

- 6x = -24

Divide both side by -6:

x = 4

Question

**Answer: 35%**

Question

Where can the numerator be found in a fraction? A. Above the fraction bar
B. At the fraction bar
C. Below the fraction bar
D. Either A or C

Solution 1

The answer is A. above the fraction bar. The denominator lives below the fraction bar.

Question

What is the excluded value of -2x/17
a. x=0
b. x=2
c. x=17
d. no excluded values

Solution 1

Answer is d: no excluded values.

There is only excluded values if the variable x is in the denominator.

There is only excluded values if the variable x is in the denominator.

Question

A circle has a circumference of 10. It has an arc of length 9/2

Solution 1

Given that a circle has a circumference of 10 and an arc of length 9/2, thus the fraction of the arc length will be:

(9/2)/10

=0.45

thus the angle subtended by the arc will be:

0.45×360°

=162°

(9/2)/10

=0.45

thus the angle subtended by the arc will be:

0.45×360°

=162°

Question

Anja collected data about the number of dogs 9th-grade students own. She created this histogram to represent the data and determined that it is skewed right. Which statement is true about Anja’s claim?

Solution 1

D) She is correct; the histogram is skewed to the right because there is less data on the right side.

Solution 2

Question

Mary has 7 1/4 yard of fabric. she cuts off 3/4 foot fabric to make the edge even. Mary wants to end up with 3 pieces of fabric that are the same size. how long will each piece be?

Solution 1

7 1/4 - 3/4 = 6 5/4 - 3/4 = 6 2/4

6 2/4 ÷ 3 = 26/4 ÷ 3 = 26/4 x 1/3 = 2 1/6

**Answer: 2 1/6 yd**

6 2/4 ÷ 3 = 26/4 ÷ 3 = 26/4 x 1/3 = 2 1/6

Question

Yun is making some investments in the stock market. Stock for Company A has a 30% chance of losing $12,000, a 45% chance of breaking even, and a 25% chance of earning Yun $11,000. Assuming Yun would like the odds to be in favor of her gaining money, should she invest in Company A? Explain. a. no, 7,700 > 3,600
b. yes, 7,700 > 3,600
c. yes, 3,600 > 2,750
d. no, 3,600 > 2,750

Solution 1

We have been given that company A has a 30% chance of losing $12,000.

Let us calculate the amount that Yun can loose.

Now, 45% chance of breaking even. It means neither loss nor profit.

Then, 25% chance of earning Yun $11,000.

Let us calculate the amount of profit

Since, 3,600 > 2,750. It means that Yun will be in loss on investing in the company.

**Hence, she will not invest in the company A.**

d is the correct option.

d. no, 3,600 > 2,750

Solution 2

D. no, 3,600 > 2,750.

Question

A lawn roller is 1 m wide and 80 cm high. What area is covered in each revolution

Solution 1

The area for each revolution is given by:

A = 2 * pi * r * l

Where,

r: roller radius

l: roller width

We have then:

A = 2 * 3.14 * (0.80 / 2) * 1

A = 2.512 m ^ 2

**Answer:**

**The area that is covered in each revolution is:**

**A = 2.512 m ^ 2**

A = 2 * pi * r * l

Where,

r: roller radius

l: roller width

We have then:

A = 2 * 3.14 * (0.80 / 2) * 1

A = 2.512 m ^ 2
