Answer:
a = 13, b = 28, c = 6, d = 22, e = 31
Step-by-step explanation:
A solid shape is made by joining two cones.
Each cone has the same radius.
One cone has
slant height = 2 × radius
The other cone has slant height = 3 × radius
The total surface area of the shape is 135. 21 cm²
Curved surface area of a cone = tırl where r is the radius and / is the slant height
Work out the radius.
The surface area of the solid shape is the amount of space on it
The radius of the two cones is 2.93 cm
How to determine the radius?The given parameters are:
Cone 1: slant height, l = 2rCone 2: slant height, L = 3rSurface area = 135. 21 cm²The surface area of the shape is calculated using:
T = πr(L + l)
So, we have:
135.21 = πr(2r + 3r)
Evaluate
135.21 = 5πr²
Divide both sides by 5π
r² = 135.21/5π
Evaluate the quotient
r² = 8.61
Take the square root of both sides
r = 2.93
Hence, the radius of the cones is 2.93 cm

Answer:
7 × 10⁴ (option D.)
Step-by-step explanation:
Take the missing value as 'x'.
5 × 10³ + x = 7.5 × 10⁴
x = (7.5 × 10⁴) - (5 × 10³)
x = (7.5 × 10000) - (5 × 1000)
x = 75000 - 5000
x = 70000
x = 7 × 10⁴ (option D.)

Which expression represents "eight less
than twice a number"?
Answer:
2n-8
Step-by-step explanation:
The expression eight less then twice a number will be shown in the following steps.
First, we tackle the first part of the sentence “Eight less” from here we can derive that there is a -8 in the expression.
Secondly, we can tackle the second part “twice a number” so this would be mean 2 times N, or 2n
From the two steps previously we can the conclude the answer must be 2n-8

A survey of customers at a restaurant revealed that 7 out of 10 customers preferred the restaurants new spaghetti sauce. Which graph shows a relationship between y, the number of customers who preferred the new spaghetti sauce, and x, the total of customers?
The graph that shows the proportional relationship y = 0.7x is Graph A.
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, 7 out of 10 customers preferred the restaurants new spaghetti sauce, hence the constant is given by:
k = 7/10 = 0.7.
And the equation is:
y = 0.7x.
When x = 0, y = 0, which already eliminates graphs C and D. When x = 10, y = 7, which means that Graph A is the answer to this question.

In the polynomial, m is the total number of miles that the customer drove the van during the day. Use the Distributive Property to write an equivalent expression for the total cost of renting the van and driving it more than 200 miles in one day
Answer:
im not sure but i think this is the answer

How much water does a cube-shaped tank with equal dimensions of 3.3 feet hold?
We need the volume
Side=a=3.3ftVolume:-
a³3.3³35.94ft³To find how much water the cube can hold
⇒ must find volume
⇒ which is the amount of space that a shape occupies, or
that is enclosed within the shape
The volume of a cube-shaped tank:
⇒ is the length, width, and height multiplied together
⇒ since this is a cube, all the side lengths are equal
⇒ Volume = (side-length)^3
Based on the information given
⇒ side-length is 3.3 feet
Therefore:
Volume = [tex]3.3^3 = 35.937ft^3[/tex]
Thus the cube-shaped tank can hold 35.937 cubic feet of water
Answer: 35.937 cubic feet of water

If the average annual interest rate is 17.11%, how many months will it take the average American family to pay off their debt of $7,942 if they make a minimum payment of $175 each month and no additional purchases are made? months.
The payoff period will be 73.56 months if the average annual interest rate is 17.11%, how many months will it take the average American family to pay off their debt of $7,942
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
We have:
Loan amount = $7942, Monthy pay = $175, Interest rate = 17.11%
After calculating from the payment formula:
The payoff = 6.13 years = 73.56 months
Thus, the payoff period will be 73.56 months if the average annual interest rate is 17.11%, how many months will it take the average American family to pay off their debt of $7,942

Answer:
80°
Step-by-step explanation:
we know angle R and angle Q are equal cause of the dashes
so
2x+30=6x-10
and then solve
30=4x-10
40=4x
10°=x
since they're equal just plug in X for one
2(10)+30= angle r
50° = angle r
we have two 50° angles and we know every triangle is 180°
so create the formula
angle r + angle q + angle p =180°
fill it in
50° + 50° + p = 180°
so angle p= 80°
