What is the height of a cone is the volume is 718.38mi^2 and the radius is 7mi?
Answer:
14 mi
Step-by-step explanation:
V = 718.38 mi³, r = 7 mi, find h
Use V = πr²h/3
718.38 = 3.14 * 7² * h/3
718.38 = 51.287 h
h = 718.38/51.287 = 14 mi

If you were to cover a pizza with cheese, how much area, rounded to the nearest whole number, would you need to cover with cheese if the pizza had a circumference of 31.4 inches?
Answer:
79 square inches
Step-by-step explanation:
First, let's find the diameter given the circumference.
[tex]C=\pi d[/tex] [tex]d=\frac{C}{\pi }[/tex] [tex]d= 31.4/3.14[/tex] [tex]d=10[/tex]Next, we know the the radius is half the diameter, so the radius is 5 inches. Now, we can solve the area of the circle.
[tex]3.14 * 5^2[/tex] [tex]3.14 * 25[/tex] [tex]78.5[/tex] 78.5 ≈ 79 square inchesTherefore, the answer is 79 square inches.

QUESTION 15
8 and the interest rate on the second loan was 9%.
Answer:
Let x = ml of 21% solution
Let y = ml of 15% solution
ATQ,
x + y = 60.....(1)
or
0.21x + 0.15y = 0.6....(2)
Multiplying equation 1st by 0.21, we get,
0.21y+0.21y =12.6....(3)
subtracting equation 3
0.21y+0.21y =12.6
-0.21x +0.15y = 0.6
_________________
ㅤㅤㅤ 0.6y = 12
_________________
6y = 12
y = 20ml
x= 60-20 = 40 ml
Hence , Conner needs 20ml of 21% solution & 40ml of 15% solution

Answer:
3 log (6/x)
Step-by-step explanation:
Rule: log(a) - log(b) = log(a/b)
3 log ( 6 ) − 3 log ( x ) = 3 log (6/x)
Find the value of x.
Answer:
12.5
Step-by-step explanation:
In this problem, we see a 5 on one side. The other side will be 5 as they have the congruent line indicator.
The formula for these types of problems are a*b=c*d.
a = 5
b = 5
c =2
d = x
(5)(5)=2(x)
x = 25/2 = 12.5
Evaluate the expression 4 exponent 3 + 96 divided by 8 times 5 - 42
Answer: 61
Step-by-step explanation: 1+12*5
Simplify the sum 43+(96/8)*5-42
1
Add 43 and -42
12*5
Reduce 96/8 by factoring out and cancelling common factors
8*12/8.1
Factor out 8 from the top and bottom of the fraction
8*12=96
8*1=8
96/8=12
multiply 12 and 5. 12*5= 60
add 60 and 1
so the answer is 61
the function of g(x) is the height of a football x seconds after it is theown in the air. The football reaches its maximum height of 30 feet in 4 seconds, and hits the ground at 10 seconds. What is the practical domain for the function f(x)?
The domain of the function will be less than or equal to 4 is x ≤ 4
Domain of a functionThe domain of a function are real values for which the function exists
For the question given, the time taken will serve as the domain of the function while the height after a particular time will be the range.
The domain depends on the time it takes to reach the maximum height. SInce the football reaches its maximum height of 30 feet in 4 seconds, hence the domain of the function will be less than or equal to 4 is x ≤ 4

thankyou ~
Explanation:
In the right triangle shown in the attachment, we have, by definition, ...
sin(θ) = a/c
cos(θ) = b/c
Then ...
sin²(θ) +cos²(θ) = (a/c)² +(b/c)² = (a² +b²)/c²
By the Pythagorean theorem, ...
c² = a² +b²
Substituting for c², we have ...
sin²(θ) +cos²(θ) = (a² +b²)/(a² +b²)
sin²(θ) +cos²(θ) = 1

A researcher decides to determine if the type of writing utensil that a student uses while doing their math affects their accuracy. A group of 1200 high school students in Algebra are randomly divided into four groups. One group uses a regular pencil, another uses a mechanical pencil, one group uses a pen and the fourth group is allowed to use whatever type of utensil they feel like. A math test is given and the results are tabulated for accuracy. The variable- type of writing utensil - is what type of variable?
Since the variable type of writing utensil assumes labels and not numbers, it is classified as qualitative.
What are qualitative and quantitative variables?Qualitative variables: Assumes labels or ranks.Quantitative variables: Assume numerical values.In this problem, the type of writing utensil has 4 labels: regular pencil, mechanical pencil, pen, whatever.

on a sheet of paper, cross of the numbers on the ends until you get to the middle.
once you have gotten to the middle you should have one number left which is 7.
because this is a uneven number there will be only one number for the median.

A construction crew is lengthening a road. The road started with a length of 54 miles, and the crew is adding 2 miles to the road each day.
Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then use this equation to find the total length of the road after the crew has worked 39 days.
FIND EQUATION AND TOTAL LENGTH OF ROAD AFTER 39 DAYS
Answer:
L=54+2d
L=54+2*39
L=54+78
L=132
Answer:
L = 2D + 54
132 miles
Step-by-step explanation:
Starting length: 54
Additional length each day: 2
On day 0, the additional length is 0.
On day 1, the additional length is 2 × 1
On day 2, the additional length is 2 × 2
On day 3, the additional length is 2 × 3
...
On day D, the additional length is 2 × D or simply 2D.
The total length after D days is the original length plus the total amount of the daily additions.
The equation is:
L = 2D + 54
On day 39, D = 39
L = 2D + 54
L = 2 × 39 + 54
L = 78 + 54
L = 132
Answer:
L = 2D + 54
132 miles

Inverso Aditivo
Inverso Multiplicativo
Números Opuestos
Números Recíprocos
Valor Absoluto
Answer:
Inverse Additive
Inverse multiplicative
Opposite Numbers
Reciprocal Numbers
Absolute value
Step-by-step explanation:
Inverse Additive is the number that is added to a given number to make the sum zero. For example, the additive inverse of 3 would be -3, because 3 + -3 = 0.
Inverse multiplicative is defined as a number which when multiplied by the original number gives the product as 1. For example, the multiplicative inverse of 5 would be 1/5, because multiplying 1/5 by the number 5 would equal to the product of 1.
Opposite Numbers- The opposite of a number is the number on the other side of 0 number line, and the same distance from 0. Basically same thing as an additive inverse. The negative version of a positive number, and vice versa.
Reciprocal Numbers- The reciprocal of a number is this fraction flipped upside down. In other words, the reciprocal has the original fraction's bottom number—or denominator—on top and the top number—or numerator—on the bottom.
Absolute value- The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign.
