Answer:
It is 36 cm
Step-by-step explanation:
In equilateral triangle, all sides are equal.
[tex]{ \sf{perimeter = side + side + side}}[/tex]
but side = 12 cm
[tex] { \sf{p = (12 + 12 + 12)}} \\ { \sf{p = 36 \: cm}}[/tex]
Answer: Perimeter = 36 cm
Concept:
Here, we need to know how to find the perimeter of an equilateral triangle.
An equilateral triangle is a triangle in which all three sides have the same length.
Perimeter (equilateral triangle) = 3s
s = side length
Solve:
Given information
Side length = 12 cm
Given expression
Perimeter = 3s
Substitute values into the expression
Perimeter = 3 (12)
Simplify by multiplication
Perimeter= [tex]\boxed{36cm}[/tex]

The point (-2, 5) is reflected over an axis and the new point is located in Quadrant 3.
a. Describe the reflection that happened. What axis was the point reflected over?
b. What are the coordinates of the new point?
9514 1404 393
Answer:
x-axis(-2, -5)Step-by-step explanation:
a) The original point is in quadrant 2. Reflection into quadrant 3 is a reflection over the x-axis.
__
b) Reflection over the x-axis changes the sign of the y-coordinate. The new point is (-2, -5).
Any recurring sequence of points above and below the trend line lasting less than one year can be attributed to the cyclical component of the time series.
a. True
b. False

Which expression is equivalent to (5^3)−2?
A 1
-
5^3
B -1/ 5•5•5•5•5•5
C 5^3
D 1/5•5•5•5•5•5
Answer:
D 1/5•5•5•5•5•5
Step-by-step explanation:
(5^3)^−2
We know a^b^c = a^(b*c)
5^(3*-2)
5^(-6)
We know a^-b = 1/a^b
1/5^6
1/(5*5*5*5*5*5)
6) Split the following into a given ratio:
a) 72 into 1:3:5:
b) 150 into 2:3:
000029
Hub
(a)
Given:
72 to be split into 1:3:5
Solution:
First divide the amount with the sum of the ratio given
72 / 1 + 3 + 5 = 72 / 9 = 8
Now multiply the answer with each value:-
8 × 1 = 8
8 × 3 = 24
8 × 5 = 40
∴ The ratio will be 8:24:40
{To check your answer add to get the exact value: 8 + 24 + 40 = 72}
(b)
Given:
150 to be split into 2:3
Solution:
First divide the amount with the sum of the ratio given
150 / 2 + 3 = 150 / 5 = 30
Now multiply the answer with each value:-
30 × 2 = 60
30 × 3 = 90
∴ The ratio will be 60:90
{Now check your answer in the same way above: 60 + 90 = 150}
Solve (x + 5)2 = 48.
Answer:
x = -5 ±4sqrt(3)
Step-by-step explanation:
(x + 5)^2 = 48
Take the square root of each side
sqrt((x + 5)^2) = ±sqrt(48)
x+5 = ±sqrt(16*3)
x+5 = ±4sqrt(3)
Subtract 5 from each side
x = -5 ±4sqrt(3)

Answer:
10 * 10 * 10
Step-by-step explanation:
Cubing a number just means you are multiplying that number 3 times to itself. Since we have 10^3, we multiply 10 to itself three times.

Answer:
initial population : 89
after 9 years : 676
Step-by-step explanation:
no need for panic. this is just plain calculator mechanics. yes, we need to do some more complicated typing and use e, but it is still only typing.
the initial population is P(0). or t = 0.
simply when there were 0 years since the fish were added.
that is simple.
we get (as -0.42×0 = 0)
800 / (1 + 8e⁰) = 800 / (1+8×1) = 800 / 9 ≈ 89
now, after 9 years we have to calculate P(9). or t=9.
let's pre-calculate : -0.42×9 = -3.78
e to the power of -3.78 = 0.022822691...
8 times this is 0.182581531...
and plus 1 is 1.182581531...
800 / 1.182581531... = 676.486127 ≈ 676
Three times the sum of a number and 2 is the same as three-fifths of the sum of the same
number and 22. What is the number?
Answer:
3
Step-by-step explanation:
3(n+2)=3/5(n+22)
3n+6=3/5n+66/5
3n-3/5n = 66/5 - 6
2.4n = 7.2
n = 7.2/2.4
n = 3

A researcher observed elementary school children in a rural setting vs. an urban setting. She believes the proportion of students who get the recommended amount of daily exercise may be different for students in the urban vs. rural setting.
Requied:
What would be the most appropriate test to test the researcher's claim?
Answer:
Go to multiple schools in urban and rural areas and find out how much exercise they get. Compare the data/research to find out if one gets more than the other, less, or equally the same amount of exericise.
