Answer:
3 and 4
Step-by-step explanation:
30/8=3.75
3.75 lies between 3 and 4
Hey there!
30/8
= 30 ÷ 2 / 8 ÷ 2
= 15 / 4
≈ 3 3/4
≈ 3.75
It falls in between three (3) and four (4). But, fun fact it rounds to up to four (4)
Good luck on your assignment & enjoy your day!

Both 12 and 2 have the factor of 2 in common. (2)(12)/12 gives us the least common LCM (least common multiple) of 12.
220,000 population grows 8%. What will population be in 7 years
Answer:
the population will be 1,540,000 in 7 yrs
Answer: 377041.34
Step-by-step explanation: if it is growing 8 percent then you will add 8 percent to 100 which will equal 108 percent
Plug that into a calculator with the starting number so it wil look like 108% 220,000 and if you do that seven times you will get the answer.
In a bag there are six red marbles, four blue marbles, and eigint green marbles. What is the probability that you will draw a green marble? 1. 1/3 2. 4/9 3. 1/18 4. 4/5
Answer:4/9 We know, Probability = Favorable Outcome / Total Outcome
Here, Favorable Outcome (Number of Green Marbles) = 8
Total Outcome = 6 + 4 + 8 = 18
P = 8 /18 = 4/9
In short, Your Answer would be 4/9 or 0.44

What is the equation of the circle?
Answer:
○ [tex]\displaystyle (x - 4)^2 + (y + 2)^2 = 25[/tex]
Explanation:
Accourding to one of the circle equations, [tex]\displaystyle (x - h)^2 + (y - k)^2 = r^2,[/tex]the centre of the circle is represented by [tex]\displaystyle (h, k).[/tex]Moreover, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to which term gets which symbol. Another thing you need to know is that the radius will ALWAYS be squared, so no matter how your equation comes about, make sure that the radius is squared. Now, in case you did not know how to define the radius, you can choose between either method:
Pythagorean Theorem
[tex]\displaystyle a^2 + b^2 = c^2 \\ \\ 4^2 + 3^2 = r^2 \hookrightarrow 16 + 9 = r^2 \hookrightarrow \sqrt{25} = \sqrt{r^2} \\ \\ \boxed{5 = r}[/tex]
Sinse we are dealing with length, we only desire the NON-NEGATIVE root.
Distanse Equation
[tex] \displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = d \\ \\ \sqrt{[-7 + 4]^2 + [-2 - 2]^2} = r \hookrightarrow \sqrt{[-3]^2 + [-4]^2} = r \hookrightarrow \sqrt{9 + 16} = r; \sqrt{25} = r \\ \\ \boxed{5 = r}[/tex]
Sinse we are dealing with distanse, we only desire the NON-NEGATIVE root.

Find the lateral area of a waffle cone with a diameter of 4.6 in. and a slant height of 7.9 in. Give your answer in terms of ℼ .
Answer:
18.17 × pi in²
Step-by-step explanation:
there are many seemingly different formulas out there for this, but they are actually all the same and differ only by what values of the cone we know at the beginning (and the custodian values are converted into the values we need for the calculation).
do we know the base area and the height of the cone, or the radius and the height, or the base area and the slant height (the length of the "mantle" straight from the bottom to the top), ... ?
well, here we know the diameter (this means it is 2 times the radius) and the slant height.
this is one of the easiest exercises.
the formula for this case is
LA = pi × radius × slant height = pi × (4.6 / 2) × 7.9 =
= pi × 2.3 × 7.9 = 18.17 × pi in²
A pawn show purchase a DVD player for $12.00 and sold it to a customer for 40% more than the purchase price. The customer was charge 7.5% tax when the DVD player was sold. What was the total, including tax?
Answer:
$18.06
Step-by-step explanation:
The price the pawn shop charged for the DVD player was 40% more than what it paid, so was ...
$12.00 + $12.00 × 0.40 = $12.00×(1 +0.40) = $16.80
__
The tax on the purchase is this price multiplied by the tax rate:
tax = 0.075×$16.80 = $1.26
__
Then the total including tax is ...
$16.80 +1.26 = $18.06 . . . . . total cost of the DVD player
Use the example above and determine the fraction of total interest owed. After the fifth month of a 12-month loan: the numerator is: {(n + ) + (n + ) + (n + ) + (n + ) + (n + )} = , and the denominator is: {(n) + (n + 1) + ... + (n + )} = . Therefore, the fraction is numerator/denominator (to the nearest tenth) = %.
The fraction of total interest owed after the fifth month of a 12-month loan is 64.1%
How to determine the fraction of interest owed?From the question, we have the following parameters
The numerator is given as: {(n+11)+(n+10)+(n+9)+(n+8)+(n+7)}The denominator is given as: {(n)+(n+1)+...+(n+11)}After the fifth month, the equation of the numerator is:
Numerator = (1+11)+(1+10)+(1+9)+(1+8)+(1+7)
Numerator = 50
The equation of the denominator is:
Denominator = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12
Denominator = 78
The fraction of total interest is then calculated using:
Fraction = Numerator/Denominator
This gives
Fraction = 50/78
Express as percentage
Fraction = 64.1%
Hence, the fraction of total interest owed after the fifth month of a 12-month loan is 64.1%

AABC is similar to ADEF. The measure of AC = 10, the measure of DE=8, the measure of BC = 6, and the measure of DF = 20.
Find the measures of AB and EF.
The measure of AB and EF for the similar triangle ABC and DEF are 4 and 12 respectively.
What are similar triangles?Similar triangles are triangles that have the same shape, but their sizes may vary.
In similar triangles, corresponding sides are always in the same ratio. The angles are congruent.
ΔABC is similar to ΔDEF. Therefore, the sides will form a ratio.
AC / DF = BC / EF = AB/DE
AC = 10
DF = 20
DE = 8
BC = 6
Hence,
10 / 20 = AB / 8
cross multiply
20AB = 80
AB = 80 / 20
AB = 4
Hence,
10 / 20 = 6 / EF
10EF = 120
EF = 120 / 10
EF = 12
