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?
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.

Hi my lovely people!

B - (6,3)
C - (1,3)
D - (8,7)
E - (8,9)
To know where to put the dots on the graph, use the coordinates you've just been given:
Example: (4,8)
Move to the 4 on the x-axis (the line on the bottom going horizontal)
Then, move up 8 units (up to the 8 on the y-axis)
Place the point at that spot.
Part 2:
A - (1,2)
B - (2,4)
C - (3,6)
D - (4,8)
Derek decorates 10 cookies in 5 minutes. We know he took 5 minutes to decorate 10 cookies because in the table, the x-axis is told to us that it represents the time it takes. Since the x coordinate is 5 in the point (5,10) and the y coordinate is 10, we can safely say that it took Derek 5 minutes to decorate 10 cookies.
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?
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.

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]

Answer:

No. Since the garage is a square, the length and width are the same. And since the formula to find the area of a square is (length times width) l x w , that means that the square root of 121 would be the length and width of the garage. The square root of 121 is 11, concluding that the car that measures 13 feet long is too large.

Answer:
B
Step-by-step explanation:
In the diagram, each square depicts ten yards (it's 60x110, and it's six blocks high and eleven blocks long). So it's one square per ten yards, which means that eleven squares will equal 110 yards.

Answer:
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%

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