PLZ HURRY! Kaylie wants to see how metals can be combined. She found a problem to solve. Help her solve it! How many pounds of a metal containing 20% nickel must be combined with 6 pounds of a metal containing 80% nickel to form an alloy containing 60% nickel?

Answers

Kaylie needs 3 pounds of the 20% nickel metal to combine with 6 pounds of the 80% nickel metal to form an alloy containing 60% nickel.

To solve the problem, we can use the concept of weighted averages. The first step is to determine the amount of nickel in each metal before they are combined.

For the 20% nickel metal, 20% of the metal is nickel. Therefore, the amount of nickel in x pounds of this metal is 0.2x.

For the 80% nickel metal, 80% of the metal is nickel. Therefore, the amount of nickel in 6 pounds of this metal is 0.8(6) = 4.8 pounds.

Next, we can use the weighted average formula to determine the amount of nickel in the alloy:

0.2x + 4.8 = 0.6(x + 6)

Simplifying the equation:

0.2x + 4.8 = 0.6x + 3.6

0.4x = 1.2

x = 3

Therefore, Kaylie needs 3 pounds of the 20% nickel metal to combine with 6 pounds of the 80% nickel metal to form an alloy containing 60% nickel.

In summary, to determine the amount of metal-containing 20% nickel needed to combine with 6 pounds of metal containing 80% nickel to form an alloy containing 60% nickel, we used the concept of weighted averages and found that Kaylie needs 3 pounds of the 20% nickel metal.

Answer:

8 : 20 and 24 : 60

Step-by-step explanation:

Given the ratio

[tex]\frac{2}{5}[/tex]

To obtain a ratio with 20 on the denominator multiply numerator and denominator by 4

= [tex]\frac{2(4)}{5(4)}[/tex] = [tex]\frac{8}{20}[/tex]

To obtain a ratio with 24 on the numerator multiply numerator and denominator by 12

= [tex]\frac{2(12)}{5(12)}[/tex] = [tex]\frac{24}{60}[/tex]

Pete wants to treat several friends to the baseball game. he has a budget of $110. tikets are $8. he will spend $20 on parking how many friends can he afford to take without going over his budget?

Answers

Answer:

He can take 11 friends.

Step-by-step explanation:

110 - 20 = 90

Then you do simple math, how many times can 8 go into 90? Well, 8 times 10 is 80, so add 8 more and you have 88 (Which is 8 times 11).

90 - 88 = 2, so you can put in anymore.

What is Addition?

Addition is a process of combining two or more numbers.

Given that dot plot shows the height of each toddler at Ms. Cabrera's daycare.

Each dot represents a different toddler.

We need to find the number of toddlers in Ms. Cabrera's daycare.

Count out toddlers of different height and add them

Two plus three plus five plus four plus one

2+3+5+4+1

Two plus three is five so

5+5+4+1ive plus five is ten

10+4+1

Four plus one is five

10+5

Hence, there are 15 toddlers in Ms. Cabrera's daycare.

Well assuming you don’t need to simplify

44/100

0.44

44%

Step-by-step explanation:

Okay so fraction is easy, theres a 100 cubes in total, 44 are shaded in, 44/100 are shaded in which is the area in this scenario.

Decimal is basically moving the place area by a specific amount, in this case theres no whole number since the whole number is 1 or 100/100 and its 44/100 right now so it can’t be a whole number. Decimals go by tenths, hundreths, thousandths, etc. so in this case 44/100 is n the hundreth place since its over a hundred so its 0.44. Or you can move it twice to the right by the times of 0 that appears.

Percent basically means out of 100. So in this case its 44 out of a hundred or 44%

So in this case it’s 44 out of a 100 or 44%
