Presuming the circle is the whole, 1/4 + 1/2 is 3/4, or 0.75, so it is 75% of the circle.

Well 1/4 is .25 and 1/5 is .5 so it would be .75 so 75%? I'm not sure if that's right, but I hope I helped!

Two glasses of milk and 3 snack bars have a total of 61 carbohydrates​ (carbs), and 4 glasses of milk and 2 snack bars have a to
Sloan [31]

Answer:

24 carbohydrates

Step-by-step explanation:

Represent Snack bars with S and Milks with M.

So, we have:

2M\ and\ 3S\ = 61

and

4M\ and\ 2S\ = 70

Required: Solve for M and S

Convert the given expressions to mathematical expressions:

2M + 3S = 61 --- (1)

4M + 2S = 70 --- (2)

Multiply the first equation by 2

2M + 3S = 61 --------- * 2

4M + 6S = 122 --- (3)

Subtract (1) from (3)

4M - 4M + 6S - 2S = 122 - 70

4S = 52

Solve for S

S = 52/4

S = 13

Substitute 13 for S in (2)

4M + 2S = 70

4M + 2 * 13 = 70

4M + 26 = 70

Solve for 4M

4M = 70 - 26

4M = 44

Solve for M

M = 44/4

M = 11

1 glass of milk and 1 snack bar = S + M

S + M = 13 + 11

S + M = 24

Joseph places $5,500 in a savings
Novay_Z [31]

Answer: About 6.2%

Step-by-step explanation:

He starts with 5500 and gains 893.75 in 2.5 years.

The equation is then 5500*(x)^2.5 = 5500+893.75, or

5500*x^2.5 = 6393.75.

x is about 1.0621, or about 6.2% because it's interest.

Hope that helped,

elixir [45]

Answer:

6.9 oz and 8.1 oz

Step-by-step explanation:

The data collected by Lucilla is as follows:

7.1 oz

6.9 oz

7.3 oz

7.6 oz

8.1 oz

7.5 oz

We need to put this data in order, this will give us:

6.9 , 7.1 , 7.3 , 7.5 , 7.6 and 8.1

We can note that:

smallest value is 6.9 oz

largest value is 8.1 oz

all other values fall in this range

Therefore, the weight of an orange based on her calculations is between 6.9 oz and 8.1 oz

Hope this helps :)

9,19,29,39,49,59,69,79,89,90,91,92,93,94,95,96,97,98,99
There are 19 of those assuming that you don't include decimals which would then make it an infinite amount.
