Rodney decides to pay a $200 fee in 3
payments. The first payment is 10% of the
original fee. The second payment is 25% of the
original fee. Which expressions represent the
amount of money for the third payment?

Answers

Answer:

65% of the orginal fee or $130.

Step-by-step explanation:

You didn't put the answer options so I am not sure how you want the question to be answered. There are three ways I would write it:

1: 100% = 10% + 25% + 65%

2: 200 = 20 + 50 + 130

3: 200 = (0.1 x 200) + (0.25 x 200) + (0.65 x 200)

All of them basically mean the same thing it is just a matter of how you need it written.

Based on the amount to be paid and the percentage paid in each installment, the expression for the third payment is 65% x 200.

Rodney has to pay $200 in three installments.

The third installment will be:

= Percentage in total - Percentages paid already

= 100% - 10% - 25%

= 65%

The third installment is therefore:

= Percentage to be paid x Amount

= 65% x 200

Natalie is on her school's swim team. Last year, she swam the 300-meter freestyle in 3 2/3 minutes. This year she swam a shorter distance of 200-meter freestlye in 3 minutes. What is her speed for per hour for each hour for each distanc

Answers

Answer:

4909 m/hr

6000 m/hr

Step-by-step explanation:

Last Year :

Distance = 300 m

Time = 3 2/3 minutes

Speed per hour = distance / time

Time in hour = 11/3 ÷ 60 = 0.0611111 hour

300 / 0.0611111 = 4909.0918 m /hr

= 4909 m/hr

This year :

Distance = 200 m

Time = 3 minutes

Speed per hour = distance / time

Time in hour = 3 ÷ 60 = 0.0333333 hour

200 / 0.0333333 = 6000.0060 m /hr

= 6000 m/hr

Answers

Answer: (x-6)(x+1)

Step-by-step explanation:

Sum : x2 − 5 x- 6

x2 + x-=6 x − 6

factor pair: x 2 + x − 6 x − 6

x( x+ 1 ) − 6 ( x + 1 )

rewrite from: x (x + 1 ) − 6 ( x + 1 )

(x-6)(x+1)

Answer:

A: (x-6)(x+1)

Step-by-step explanation:

We need to find 2 numbers that add to make -5 and multiply to make -6.

We already have the numbers infront of us, so by process of elimination we can remove B and D.

For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.

If we expand A, it makes the expression that needs to be factorised because...

-6 × 1 = -6

-6 + 1 = -5

So expanding it properly we get.

x² - 6x + x - 6

Simplify.

x² - 5x -6

Shen invested in a savings bond for 2 years and was paid simple interest at an annual rate of 2% the total interest that he earned was $28 how much did he invest

Answers

Answer:

Principal = $700

Step-by-step explanation:

Simple interest = principal × rate × time

Simple interest = $28

Rate = 2% = 0.02

Time = 2 years

Principal = x

Simple interest = principal × rate × time

28 = x * 0.02 * 2

28 = 0.04x

x = 28/0.04

x = $700

Principal = x = $700

His face seemed like it was on fire and itched something awful! He jumped out of bed and rushed to the bathroom and splashed water on his face, but it really didnt help. He looked closely in the mirror, and the whole right side of his face was red. Alarmed, he yelled for his mother, who rushed into the bathroom. Whats wrong? she asked. Why are you screaming? Look at my face, Curtis said and turned to her. His mother put her glasses on and bent down to examine his face. She touched the red area and pushed his hair back. It itches like crazy, he said. She turned his head to one side so the light was better and touched the red area again. Try not to scratch it, she said, thatll just make it worse. Dont you have something you can put on it? Come into my bathroom, and Ill put some lotion on it, she said. The lotion helped a little; at least Curtis didnt feel like he wanted to scratch his face off. What do you think it is? he asked his mother. Well, it looks like something bit you, she said, maybe a spider. In my bed? he asked and shivered involuntarily. Maybe, but werent you and Trevor playing in the woods yesterday? she asked. Thats right, we were, but nothing bit me. She turned his face to get a better look. Whether it was in the woods or in your bed, something definitely bit you right there on your cheekbone, she said. I can see the mark clearly in this light. Were going to have to take you to the clinic. But I have school today, and I havent missed school all year. Cant I go to the school nurse? I think the lotion is really working, he added hurriedly. This last statement was not really true as his face was still hot and itchy, but Curtis was determined to get a perfect attendance award at the awards assembly in May. Id feel better if Dr. Cline looked at it. She can recommend a skin cream that will help you feel better. Go get dressed while I call the clinic.
