Answer:
(√50+15/2)/2=√50/2+15/4=7.28
√8+4=6.82
π+4=7.14
13√80/16=7.26
3π-2=7.424
√30+1.8=7.277
Step-by-step explanation:
√30+1.8 is nearly equal to√30+1.8&13√80/16
so
√30+1.8& 13√80/16 can be apply.
A certain forest covers an area of 3900 km^2. Suppose that each year this area decreases by 6.75%. What will the area be after 12 years
Answer:
1686
Step-by-step explanation:
Rate of reduction = 100 - 6.75 = 93.25%
After 12 years, the reduction in trees = 0.9325^12 = 0.432301
Area after 12 years = 3900 x 0.432301 = 1686

Answer:
-4(y+4)Step-by-step explanation:
Factors is something that influences something else.
Distributive property:
A(B+C)=AB+AC
16=4*4
Rewrite the problem down.
-4y-4*4
Solve.
Find the common term of -4.

Given a polynomial f(x), if (x − 3) is a factor, what else must be true?
f(3) = 0
f(−3) = 0
f(0) = 3
f(0) = −3
Answer:
A
Step-by-step explanation:
Recall that according to the Polynomial Remainder Theorem, if we divide a polynomial f(x) by a binomial in the form (x - a), then the remainder will be f(a).
And by the Factor Theorem, in order for a binomial (x - a) to be a factor of a polynomial f(x), the remainder must be 0. In other words, f(a) = 0.
We are given a polynomial f(x) and that (x - 3) is a factor.
Therefore, a = 3.
And since it is a factor, by the Factor Theorem, the remainder must be 0.
Therefore:
[tex]f(3)=0[/tex]
The answer is A.
Answer:f(−3) = 0

Find the perimeter of the following rectangle. Hint: add all sides.
Answer:
A
Step-by-step explanation:
The formula for the perimeter is 2l +2w. 4x^2+4x^2=8x^2. y^2+y^2=2y^2.
If we add them together the answer is 8x^2+2y^2.

After winning a soccer game, the coach took the team out for ice cream cones. He spent $21 on 12 single-scoop ice cream cones. If all the ice cream cones cost the same amount, what was the cost of one ice cream cone?
Answer:
Unitary cost= $1.75
Step-by-step explanation:
Giving the following information:
He spent $21 on 12 single-scoop ice cream cones.
To calculate the unitary cost, we need to use the following formula:
Total cost= number of units*unitary cost
Unitary cost= total cost / number of units
Unitary cost= 21 / 12
Unitary cost= $1.75
-15.3 = -7.5k + 55.2
Answer:
k=0.1
Step-by-step explanation:
-15.3=-7.5k+55.2
7.5k=15.3+55.2
7.5k=70.5
k=70.5/7.5
k=705mul.10/75mul.10
k=705/0/750
k=0.1

Mrs. Hooper teaches piano lessons 5 days a week. She teaches for a total of 3 hours per day. How many minutes does she teach each week?
Answer:
900 minutes a week
Step-by-step explanation:
60 minutes makes one hour
3 hours multiplied by 60 minutes is 180 minutes
180 minutes multiplied by 5 days is 900 minutes
Step-by-step explanation:
3 hours *60 minutes= 180 minutes
And if he teaches for 180 mins a day, then in 5 days he will teach:
180 mins*5 days= 900 mins

A paper container in the shape of a right circular cone has a radius of 3 inches and a height of 8 inches. Determine and state thr number of cubic inches in the volume of the cone, in terms of π.
Given:
Radius of the cone = 3 inches
Height of the cone = 8 inches
To find:
The volume of the cone, in terms of π.
Solution:
We know that, the volume of a cone is:
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Putting [tex]r=3,h=8[/tex], we get
[tex]V=\dfrac{1}{3}\pi (3)^2(8)[/tex]
[tex]V=\dfrac{1}{3}\pi (9)(8)[/tex]
[tex]V=\dfrac{72}{3}\pi [/tex]
[tex]V=24\pi [/tex]
Therefore, the volume of the cone is [tex]24\pi[/tex].

The area of a round table in Kim's living room is 201 square inches. What is the circumference of the round table in inches?
Use 3.14 for π and round to the nearest hundredth of an inch if necessary
A. 8
B. 25.12
C. 50.24
D.100.48
Answer:
A. 8
Step-by-step explanation:
You must take the area and divide it by [tex]\pi[/tex]
201 divided by 3.14
Then take the number you got
201 divided by 3.14 = 64.0127388535
Then find the square root of that number
[tex]\sqrt 64.0127388535[/tex] = 8.000796139
Simplify & you get 8.
