what is 7 times 3 fiths
Answer:
4-1.5 or 21/5 or 4.2
Step-by-step explanation:
Multiple: 7 * 3/5 = 7 · 3/1 · 5 = 21/5
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(21, 5) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seven multiplied by three fifths = twenty-one fifths.
A large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large cheese pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping.

Answer:
12
Step-by-step explanation:
This thing to know about this question is that angle 1 and angle 3 are actually the same.
When two lines intersect, the opposite angles such as that shown in 1 and 3 are equal to each other.
So what you can do is set angle 1 and 3 equal to each other like so:
5x+10 = 70
Then solve for x
5x+10 = 70
5x = 60
x = 12

Adam is purchasing a new television that costs $2,187.96 after tax. He borrowed the money from his parents and must pay back the full amount plus simple interest at the rate of 3.5%. What is the interest he will pay if he takes 2 years to pay his parents back? (Include Decimal with the cents; No Commas)
Using simple interest, considering the parameters stated in the exercise, it is found that he will pay an interest of $153.16.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
I = Prt
In which:
P is the initial amount.r is the interest rate, as a decimal.In this problem, the parameters are given as follows:
P = 2187.96, r = 0.035, t = 2.
Hence, the interest paid will be of:
I = Prt = 2187.96 x 0.035 x 2 = $153.16.

What is the volume of this cone? Use 3.14 for π and round your answer to the nearest tenth.
In your answer, give the volume of the cone rounded to the nearest tenth, and then explain how you calculated it.
Answer:
volume = 33.5 in³
Step-by-step explanation:
Formula:
[tex]\sf volume \ of \ a \ cone=\dfrac13\pi r^2h[/tex]
Given:
r = 2 inh = 8 inπ = 3.14Substituting the given values into the formula:
[tex]\sf \implies volume=\dfrac13 \times 3.14 \times 2^2 \times 8[/tex]
[tex]=\dfrac13 \times 3.14 \times 4 \times 8[/tex]
[tex]\sf =33.49333333...[/tex]

The volume of a cylinder is 81 pi in^3 and the height of the cylinder is 1 in. What is the radius of the cylinder
Answer:
18/20π
Step-by-step explanation:
81π ÷ 1 = 81π
81π ÷2 = 18/20π
You do this because the radius is half of the diameter and you need to get rid of the hight by dividing it from the volume.

If x = 9 units , y = 3 units , and h= 11 units what is the area of the trapezoid
Hey there!
Your area of a trapezoid
a = a + b / 2(h)
area = base + base / 2(height)
YOUR EQUATION:
area = 9 + 3 / 2(11)
area = 12/2(11)
area = 6(11)
area = 66
Thus, your answer is probably: 66

-7/3y-2/9=1/3 solve for y
Answer:
y = -12
Step-by-step explanation:
-7/3y - 2/9 = 1/3
cross multiple for 1/3:
-21/3y - 6/9 = 1
cross multiply for 3y and 9:
-21 - 6 = 3y + 9
3y + 9 = -27
3y = -36
y = -12

Determine the value of x if the mode is 18
Find the measure of the indicated arc
Step-by-step explanation:
we need the length of the arc ?
the length of the arc fully around the circle (360°) is the circumference of the circle : 2×pi×r
and the arc length for 123° is then
2×pi×r×123/360
but we would need r to calculate that. you did not provide that.
the only other thing that comes to mind is : the arc angle is indeed the angle at the center of the circle and is 123°.
