You have a coupon for 10% off the sale price of a surfboard. Which is the better buy? Explain your reasoning.

● 40% off the regular price
● 30% off the regular price and then 10% off the sale price
40% of $150 = _, so the sale price is _
30% of $150 = _, so the sale price is _
10% of that sale price is _,so after using the coupon, the sale price is _

Answers

Answer 1

Answer:

* 60 -$60 <- answer

* 45- $45 <- answer

94.5- $94.50 <- answer

Step-by-step explanation:

40%= 0.4 ×150=60

30%=0.3×150=45

60 +45= 105

(105*10)/100= 10.50

105-10.50=$94.50 <- answer

In order to find the solution, You would first line line the equation up. then, you would subtract -200 by 15. The answer would be -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive. If you had a positive 201 plus -200 the answer would be equivalent to a positive one because the positive would cancel out the negative.

Included: Negative, positive, equivalent.

explanation/ statement:

"I think I should subtract -200 by 15. which one equal -185. I know the answer will be negative because -200 is too big for 15 to make the solution positive.

Answers

Answer:

Step-by-step explanation:

theyy both go into 18

The least common multiple (LCM) of 6 and 9 is 18. so, the correct answer is B. 18.

To find the least common multiple (LCM) of 6 and 9, we can list their multiples and look for the smallest common multiple.

The first 5 multiples of 6 are

6, 12, 18, 24, 30.

The first 5 multiples of 9 are

9, 18, 27, 36, 45.

From these lists, we can see that the smallest common multiple of 6 and 9 is 18.

Therefore, the correct answer is B. 18.

What should the following rate be divided by to convert it to a unit rate?

6 inches
________

Answers

Answer:

Unit rate is a rate that has 1 as denominator.

Given the rate: 6 inches / 12 hours, we have to divide numerator and denominator by 12 to transform the denominator in 1, as follows:

\frac{6}{12} = \frac{6/12}{12/12} =

12/12

Part B
How much interest would Mia pay if the simple interest rate were 5%? Enter your answer in the box.

Answers

Answer:

Part A: She borrowed: 3700

Part B: She would pay 555 in interest.

Step-by-step explanation:

Since, simple interest is,

Where, P is the principal amount,

r is the annual rate of interest,

t is time ( in years ),

Part A : Here, S.I. = $ 444,

t = 3 years,

r = 4 %,

Thus,

Hence, She borrowed $ 3700.

Part B :

Here, r = 5 %, t = 3 years, P = $ 3,700,

Hence, She would pay $ 555 interest.

The Hamptons Family has a fish tank holding 10,450 ml of water. The water is leaking at a rate of 270 ml per minute.

Part A: Define the input and output in the given scenario.

Part B: Write a function to model this situation.

Part C: How many liters of water will be left in the tank after 10 minutes
(hint: liters, not milliliters)

Answers

Answer:

The output would depend on the input so relating this to the question, the input is the time (in minute) and the output is the amount of water left in the tank

We can give a letter 't' for the time, the input, and f(t) for the output

----------------------------------------------------------------------------------------------------------------

The original amount of water in the tank is 10450, so this will be the fixed constant.

The amount of water lost per minute is 270 so this will be the term that varies depends on the variable of time, we write this as 270t

The function is given f(t) = 10450 - 270t

--------------------------------------------------------------------------------------------------------------

Given, t = 10

f(10) = 10450 - 270(10)

f(10) = 7750 ml

Step-by-step explanation:

Answer:

Part A:

Since the rate of 270 ml per minute has units of ml per minute, then yy must have units of ml and x must have units of minutes. The input must then be the number of minutes the tank is leaking for and the output is the number of ml of water remaining in the tank.

Part B:

Since the tank is leaking 270 ml per minute, then after x minutes, 270x ml of water has leaked out of the tank. The tank initially has 10,450 ml of water so after x minutes, there is y=10,450−270x ml remaining in the tank.

Part C:

After x=10 minutes, the amount of water remaining in the tank is y=10,450−270(10)=10,450−2,700=7,750 ml. There are 1,000 ml in 1 liter so 7,750 ml = 7.75 liters. There are then 7.75 liters of water left in the tank after 10 minutes.

Write 16 + 32 as a product of two factors using the GCF and the distributive property.
16 + 32 = ? (4, 8, 16, or 32 are the numbers below the question mark) ( ? + ? ) (1, 2, 4, and 8 are below both of the question marks in the parentheses)

Answers

Answer:

16 (1+2)

Step-by-step explanation:

factors of 16: 1,2,4,8,16

facfors of 32: 1,2,4,8,16,32

16 x 1 = 16

16 x 2 = 32

We are required to write 16 + 32 as a product of two factors using the GCF and the distributive property.

16 + 32 as a product of two factors using the GCF and the distributive property is 16(1 + 2)

given:

16 + 32

Factors of 16 = 1, 2, 4, 8 and 16

Factors of 32 = 1, 2, 4 8, 16 and 32

The highest common factor of 16 and 32 is 16

check a factor of 16 that can multiply 16 to give 16

= 16 × 1

check a factor of 32 that can multiply 16 to give 32

= 16 × 2

So,

(16 × 1) + (16 × 2)

= 16(1 + 2)

Therefore,

16 + 32 as a product of two factors using the GCF and the distributive property is 16(1 + 2)
