A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
0.7 and 43.2%.
To write decimal as a percentage:
Multiply by 100,
So,
0.7 x 100 = 70%
To write percentage as a decimal:
Divide by 100,
So,
43.2/100 = 0.432.

Answer:
3%
Step-by-step explanation:
739 - 716 = 23 (change)
percentage change = change/original price X 100

115°
A 45°
B. 550
C. 57.59
D. 22.50
Answer:
A. 45°
Step-by-step explanation:
By exterior angle theorem:
x + 70° = 115°
x = 115° - 70°
x = 45°
Answer:
x= 45°
Step-by-step explanation:
triangles degrees all together are always 180°
x≠180°
a straight line is also 180°
180°-115°= 65°
70°+65°= 135°
180°-135°= 45°

In order to help her save money for college, Latasha's grandparents deposited $10,000 into a savings account five years ago. Latasha has not made any withdrawals or deposits since then. The interest rate on the savings account is 3.75% each year.
Using simple interest, how much interest has accrued in Latasha's savings account?
What is the total amount in Latasha's savings account?
Answer:
$11,875
Step-by-step explanation:
3.75×5 = 18.75%
[tex]\frac{18.75}{100}[/tex]×10000 = 18.75 × 100 = 1875 (we cut the zeros so that it will be easier to solve the equation)
10,000 + 1875 = $11,875 after 5 years
$1875 has accrued in Latasha's savings account
$11,875 is the total amount in Latasha's savings account after 5 years
Evaluate the following expression:
{23x[8x(54/3)]}
2(3x – 1) = 6x – 2 number of solutions
Answer: All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
2(3x−1)=6x−2
Step 1: Simplify both sides of the equation.
2(3x−1)=6x−2
(2)(3x)+(2)(−1)=6x+−2(Distribute)
6x+−2=6x+−2
6x−2=6x−2
Step 2: Subtract 6x from both sides.
6x−2−6x=6x−2−6x
−2=−2
Step 3: Add 2 to both sides.
−2+2=−2+2
0=0

Suppose that when a car goes over a bump, the impact hat must be absorbed by the suspension is directly proportional to the square of the car's speed. Of a car going 12 mph receives 4000 units of impact, ow much impact will a car received at 30 mph
Answer:
10000 units of impact
Step-by-step explanation:
From the above question:
12 mph = 4000 units of impact
30 mph = x units of impact
Cross Multiply
12 mph × x units = 30 mph × 4000 units
x units = 30 mph × 4000 units/12 mph
x units = 10000 units of impact.
Therefore, 30 mph receives 10000 units of impact

The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.
How tall are the types of trees that Logan genetically engineered?
Answer:
The pine is 12 m tall and the fir is 12 m tall
Step-by-step explanation:
System of Equations
Let's call:
x = height of a pine tree
y = height of a fir tree
The combined height of one fir tree and one pine tree is 21 meters. This leads to the equation:
x + y = 21 [1]
The height of 4 fir trees is 24 meters taller than one pine tree:
4y = x + 24 [2]
From [1]:
x = 21 - y [3]
Substituting in [2]:
4y = 21 - y + 24
Adding y:
5y = 45
Dividing by 5:
y = 9
Substituting in [3]:
x = 21 - 9 = 12
The pine is 12 m tall and the fir is 12 m tall
