Hello there,
Part 1:
Perimeter of Red = 11+11+11+11 
                            = 44
Perimeter of Blue= 6+6+6+6
                            = 24
Ratio: Red : Blue
             44 : 24(divide by 4) 
              11 : 6
Part 2:
Area of Red= 11 x 11
                   = 121
Area of Blue= 6 x 6
                   = 36
Ratio: Red : Blue
             121: 36
             
Hope this helps :))

PLEASE HELP ASAP
neonofarm [45]

Answer:

9 Quarters

8 Dimes

3 Nickels

Step-by-step explanation:

We let the number of quarters be q

number of dimes be d

and

number of nickels be n

Since quarters are worth 0.25, dimes are worth 0.10 and nickels are worth 0.05 and total worth is 3.20, we can write an equation as:

0.25q + 0.10d + 0.05n = 3.20

Next,

3 times as many quarters as Nickels, we can write:

q = 3n

and

5 more dimes than nickel, we can write:

d = n + 5

Substituting these last 2 equations in the first and solving for n gives us:

0.25q + 0.10d + 0.05n = 3.20

0.25(3n) + 0.10(n+5) + 0.05n = 3.20

0.75n + 0.10n +0.5 + 0.05n = 3.20

0.9n = 2.70

n = 2.70/0.9 = 3

n = 3

We know q = 3n, so

q = 3(3) = 9

Also, we know d = n + 5, which means:

d = 3 + 5 = 8

Thus,

There are:

9 Quarters

8 Dimes

3 Nickels

Osvoldo has a goal of getting at least 30%, percent of his grams of carbohydrates each day from whole grains.
Pachacha [2.7K]
To answer this you need to figure out what 30% of the total number of carbs need to be whole-grain. Multiply 0.3 times 220 to get 66 grams. He did not meet his goal. Because he only ate 5 g, this is 61 less than he needs to meet his goal.

I have 38274938 apples. I was robbed yesterday and I lost 38474 apples. How many apples do I have left
Nesterboy [21]
Taking 38274938 to be the initial value of the number of apples we have
Now we have to subtract 38474 as we lost these apples

38274938-38474 = 38236464

Thus we have only 38236464 apples left
