The answer would be y=2/3x+3 because you have to get it into slope intercept form by dividing 3 on both sides.
The y intercept would be (0,3) then the slope would be 2/3x so you move up 2 then to the right 3

You went to the mall with $80. You spent 25% of your money on a pair of shorts and 65% of the remainder on sandals. How much did you spend on the sandals?

Answers

Answer:

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.

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.

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:

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,

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)
