Answer:

4.5

Step-by-step explanation:

If 2/5 is blue, that means 3/5 is white. Now I convert it to a decimal: 0.6. That means 60% of the paint is white, so I can do 7.5*0.6 to find how much white paint was in there. Click thanks and Brainliest if it helped! Have an awesome day :D

Hannah is saving money for a car. She earns $160 each week working part time after school and on the weekends at Papa's Pizza. H
Yuliya22 [10]
From the problem we know that Hanna saves one-half of her paycheck each week, so she saves ( \frac{1}{2})(160)= \frac{160}{2} =80. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is 80+50=130.
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>n representing the number of weeks, we can model the situation as follows:
f(n)=1280+130n

X^2 + y^2=40 and y=x-4 solve this simultaneous equation
inn [45]
Write x-4 instead of y.
x²+(x-4)²=40
x²+x²-8x+16=40
2x²-8x-24=0
x²-4x-12=0
(x-6)(x+2)=0
x=6 or x=-2

for x=6, y=6-4 = 2
for x=-2, y=-2-4 = -6

a pack rat has 130 piglets and 110 books. She wants to maintain this ratio in her collection but needs to sell some of her items
bija089 [108]

The number of items she should sell from her collection is 24

<h3>How to determine the number of items she should sell from her collection?</h3>

From the question, we have the following parameters that can be used in our computation:

Ratio = Piglets : Books

For 130 piglets and 110 books, we have the following representations

Ratio = 130 : 110

Also, for 13 piglets, we have the following representations

Ratio = 13 : Books

Using the above as a guide, we have the following:

13 : Books = 130 : 110

This can also be rewritten as

Books : 13 = 110 : 130

Multiply the second ratio by 1/10

So. we have

Books : 13 = 11 : 13

By comparison, we have

Books = 11

So, the total items sold is

Items = 11 books + 13 piglets

Evaluate

Items = 24 items

Hence, the number of items is 24
