A pharmacist mixes two different strengths of peroxide. If she mixes a 1% with a 9% solution to obtain 60mL of a 4% solution, how many mL of each type of solution does she need?

Answers

Answer 1
Pretty sure it’s 8.4 ml

Explanation:

Add all the percentages=14%

Divide 14% by 60ml
* EX. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.*
You get 8.4ml

Write an expression that is equivalent to three over four (5z+ 16).

15 over four z + 16
15 over four z + 12
three over four z + 16
three over four z + 12

Answers

Your answer is 15 over four z + 12. Using the distributive property, 3/4 • 5z equals 15/4z, which can't be simplified. Then 3/4 of 16 is 12. If you divide 16 by 4 (the denominator) and then multiply by 3 (the numerator) that yields your answer.

-5/6 - 17/18 + 2/9 (Since there are two negatives near the end, and their tecxhnically being mulitplied, -2/9*-1 (I added 1 for place holder) and when you multiply a negatives by a negative, you get a positive.

So find the lcm of the denominators which is 18 in this case

-15/18 - 17/18 + 4/18

Now solve the problem from left to right

you’ll get -1 5/9 if you simplified

Cheerios $3.89 for 17 oz. $ [ Select ] per ounce VS. Option 2: Apple Jacks $2.89 for 13 oz. $ [ Select ] per ounce Which is the better deal?

Answers

I think your best bet is to go with Apple Jacks.
The better deal is Cheerios because
If you take the ounces for each (17 & 13)
And divide them by the price ($3.89 & 2.89)
It would give you the amount 1 ounce would be (aka the constant) and the constant for Cheerios is 4.3701 where as the constant for Apple Jacks is 4.4981. Therefore, Cheerios is the better deal cause you get more.

(B) The amount of shaved ice on top of the cone is
______ π cubic inches.

(C) The total amount of shaved ice used to make the cone is
______ π cubic inches.

Answers

Answer:

(A) The amount of shaved ice inside the cone is 2.625π cubic inches.

(B) The amount of shaved ice on top of the cone is 2.25π cubic inches

(C) The total amount of shaved ice used to make the cone is 4.875π cubic inches.

Step-by-step explanation: I got the answers wrong on Time4Learning, Then it told me the correct answers. I hope this can help someone else get it correct!

The amount of shaved ice inside the cone and on top of the cone is 2.625 π and 2.25 π cubic inches. Then The total amount of shaved ice used to make the cone is 4.875 π cubic inches.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Ice cream is the combination of the cone and hemisphere.

Height of cone (h) = 3.5 in

Radius of come and hemisphere (r) = 1.5 in

(A) The amount of shaved ice inside the cone will be

[tex]\rm Volume\ of \ cone = \dfrac{1}{3} \pi r^2 h \\\\Volume\ of \ cone = \dfrac{1}{3} \pi 1.5^2 * 3.5\\\\Volume\ of \ cone = 2.625 \ \pi[/tex]

The amount of shaved ice inside the cone is 2.625 π cubic inches.

(B) The amount of shaved ice on top of the cone will be

[tex]\rm Volume\ of \ hemisphere= \dfrac{2}{3} \pi r^3 \\\\Volume\ of \ hemisphere= \dfrac{2}{3} \pi 1.5^3\\\\Volume\ of \ hemisphere= 2.25 \ \pi[/tex]

The amount of shaved ice on top of the cone is 2.25 π cubic inches.

(C) The total amount of shaved ice used to make the cone will be

[tex]\rm Total\ amount = Volume\ of \ hemisphere + Volume\ of \ cone\\\\Total\ amount = 2.625+ 2.25 \\\\Total\ amount = 4.875[/tex]

The total amount of shaved ice used to make the cone is 4.875 π cubic inches.

Step-by-step explanation:

divided the cost by the amount

4.68/16

Answer:

$0.29 per ounce of jelly

Step-by-step explanation:

Because you have to divide $4.68 by 16.

Which is $0.2925.

And to round $0.2925 you have to keep it the same and not round up because 2 is not big enough to round this number.
