Answer:
3:2
Step-by-step explanation:
If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B. For example, if A is five and B is 10, your ratio will be 5/10.
for this problem we use 0.90 and 0.60, so our ratio is 0.90/0.60
using whole numbers can be converted now by actually dividing these data points and then multiplying to a whole number:
0.9/0.6 = 1.5
1.5 x 2 = 3
this gives 3/2 = 1.5
so we know that the ratio is 3:2 and this is the smallest whole number that it could be

If the area of C is
400 ft2 and the
perimeter of B is 64 ft,
what is the side length
of square A?
[tex]\\\text{Side length of square A = a \text{ft}}\\\\\text{Side length of square B = b \text{ft}}\\\\ \text{Side length of square C = c \text{ft}}\\\\ \text{Given that,}\\\\\text{Area of square C} = 400 ~ \text{ft}^2\\\\\implies c^2=400~~~~~~......(i)\\\\\\\text{Perimeter of square B } = 64~ \text{ft}\\\\\implies 4b = 64\\\\\implies b = \dfrac{64}4\\\\\implies b = 16\\\\\implies b^2 = 256~~~~~~~.....(ii)\\\\\\[/tex]
[tex]\text{Applying Pythagorean theorem,}\\ \\~~~~~c^2 =a^2 +b^2\\\\\implies a = \sqrt{c^2 - b^2}\\ \\\implies a = \sqrt{400-256}\\\\\implies a = \sqrt{144}\\\\\implies a = 12[/tex]
[tex]\text{Hence, the side length of square A is 12 ft.}[/tex]
Mia is designing a cake for a birthday party. She plans for a total of 12 guests, each of whom may eat a piece of cake that has a volume of 8 cubic inches. Which of the following cakes would provide enough cake for each guest to have one piece of cake, with the least amount left over?
Square cake: side = 8 in., height = 2 in.
Round cake: diameter = 6 in., height = 3 in.
Round cake: diameter = 8 in., height = 3 in.
Rectangular cake: length = 6 in., width = 9 in., height = 2 in.
The square cake can be distributed in such a way that each person out of 15 guest may get 8 [tex]inch^{3}[/tex], with the least amount left over .
The Correct option is (1).
What is Volume of any shape?The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.
First find the volume of square cake,
Volume = l x b x h= 8 x 8 x 2
=128 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{128}{15}[/tex]
= 8.533 [tex]inch^{3}[/tex]
2.Volume of round cake (d= 6 inch, r=3 inch, h= 3 inch)
Volume= [tex]\frac{1}{3} \pi r^{2} h[/tex]
= [tex]\frac{1}{3} *3.14 *3^{2}* 3[/tex]
=[tex]3.14*9[/tex]
=28.26 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{28.26}{15}[/tex]
= 1.884[tex]inch^{3}[/tex]
3.Volume of round cake (d= 8 inch, r=4inch, h= 3 inch)
Volume= [tex]\frac{1}{3} \pi r^{2} h[/tex]
= [tex]\frac{1}{3} *3.14 *4^{2}* 3[/tex]
=[tex]3.14*16[/tex]
=50.24 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{50.24}{15}[/tex]
= 3.349 [tex]inch^{3}[/tex]
4. Volume = l x b x h
= 6 x 9 x 2
=108 [tex]inch^{3}[/tex]
Now there are total 15 guests, Each of get
=[tex]\frac{108}{15}[/tex]
= 7.2[tex]inch^{3}[/tex]
According to question each person may get 8 [tex]inch^{3}[/tex].
Only the square cake can be distributed in such a way that each person may get 8 [tex]inch^{3}[/tex], with the least amount left over .

a.single-payment fixed annuity
b.recurring-payment fixed annuity
c. recurring-payment variable annuity
D.single-payment variable annuity
Answer:
single payment variable annuity
Step-by-step explanation:
Given : ABC Insurance offers an annuity with 4.5% APR for the next 5 years. You decide to invest $1000 each year into this account.
To find : What type of annuity is this?
Solution :
Annuity is the form of insurance in which some of the money is paid each year to secure for future.
There are two types of annuity:
Single payment variable annuity - In this annuity the payment is made at the end of each period over a fixed length of time. Also in this annuity payments are made monthly, quarterly, semi-annually or annually.
Annuity due - is the opposite of single payment variable annuity as in this the payment is made at the beginning of each period.
In the given situation the annuity is single payment variable annuity because the investment is done each year for 5 years.

A group of 8 friends arrive at a party.
They increase numbers by 20%. How
many people now at the party?
The number of people at the party now is 23.
The percentage of a number is the fraction of that number multiplied by 100. Percentages are represented with this sign: %.
3 friends arrive at a party. The percentage of people increase by 20%.This can be represented with this equation:
p x 20% = 3 people
where p is the number of people at the party before the friends arrived.
p = 3 / 20%
p = 3 / 0.20
p = 15 people
The total number of people at the party now : 15 + 8 = 23.

The chocolate candy below is being wrapped in a cardboard box. How many square centimeters area needed for the box?
The total area of cardboard needed is equal to 121.34 square centimeters.
How many square centimeters area needed for the box?This is equal to the surface of the given chocolate.
First, we will have two sides that are rectangles measuring 16cm by 2.6cm, so the area is:
[tex]A = 16cm*2.6cm = 41.6cm^2[/tex]
Then we have another rectangular side which is the bottom one, that is a rectangle of 2.2cm by 16cm, so the are is:
[tex]A' = 2.2cm*16cm = 35.2cm^2[/tex]
Finally, we have the areas of the two triangular faces, the areas of these are:
[tex]A'' = 2.2cm*3cm/2 = 1.47cm^2[/tex]
Then the total area of cardboard needed is:
[tex]area = 2*A + A' + 2*A'' = 2*41.6cm^2 + 35.2cm^2 + 2* 1.47cm^2 = 121.34 cm^2[/tex]

Total surface area of the cube = 9 inch² x 6 = 54 inch²
Matt mixes 4 pints of ice cream and 1 1/2 pints of milk to make a milkshake. He drinks 2 cups of the milkshake. How many cups are left? Will give brainliest
Answer:
7 1/2 cups
Step-by-step explanation:
First, convert the measure of ice cream from pints to cups:
1 pint = 2 cups
⇒ 4 pints = 4 × 2 = 8 cups
Therefore,
Milkshake = 8 cups of ice cream + 1 1/2 cups of milk
= 9 1/2 cups
If he drinks 2 cups of milkshake:
Remaining milkshake = 9 1/2 - 2
= 7 1/2 cups
1pint=2cups

Explanation needed please!! I'm confused on how to solve.
Answer:
0** (READ BELOW)
Step-by-step explanation:
First, solve for g(0). Since g(0) = 3x +2, we plug in 0 for x.
So,
g(0) = 3(0) + 2 = 0 + 2 = 2.
Now that we have an answer for g(0), we can plug it into f(x).
So,
f(x) = (x-2)/3
f(x) = f(g(0)) = f(2).
f(2) = (2-2)/3 = 0/3 = 0.
Thus, f(g(0)) = 0.
Essentially, you first solve for g(0) and use the answer from that to solve for f(x) where x is your answer from g(0).
**I was unsure of what the equation was for f(x) based on how you wrote it in the question, but I assumed it was f(x) = (x-2)/3.
