Answer:
8%
Step-by-step explanation:
70.20-65=5.20
5.20/65 x 100 = 8
PERIOD!!!
Answer:
8%
Step-by-step explanation:
$65.00 + 8% = 70.2
65 x (1 + 8%) = 65 x (1 + 0.08) = 70.2
How to do it:
$70.20 - $65 = 5.20
$5.20/$65 x 100 = 8%

How do we use fractions that equal 1 to create equivalent fractions?
Do you think that we should always express fractions in the lowest terms? (9/12 = ¾)
Answer:
no
Step-by-step explanation:
The reason is if you have to add 3/4 + 7/12 you would have to convert it to have the same denominator for both fractions.

James is tracking the changes in barometric pressure (measured in inches of mercury – inHg) for his science class. On Monday the pressure was 30.01inHg. The pressure dropped by 0.34 inHg on Tuesday, before climbing 1.32 inHg on Wednesday. What was the barometric pressure reading for Wednesday?
Answer:
30.99 inHg.
Step-by-step explanation:
First, subtract how much the pressure dropped on Tuesday from Monday's reading. 30.01 inHg - 0.34 inHg = 29.67 inHg
Then, add how much the pressure climbed on Wednesday to Tuesday's reading. 29.67 inHg + 1.32 inHg = 30.99 inHg
Answer:
The barometric pressure reading for Wednesday was 31.01inHg. This can be calculated by subtracting 0.34inHg from the pressure reading on Monday (30.01inHg) and then adding 1.32inHg, which results in 31.01inHg.

The expressions that represent the area of the quadrilateral shown is first and last options.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given is a quadrilateral.
This can be divided into known quadrilaterals to find the area.
This can be done in two ways as shown in the image below.
Area of rectangle/square = Length × Width
Area of triangle = [tex]\frac{1}{2}[/tex] × base × height
As shown in the first figure,
Area of the quadrilateral ADGH = Area of rectangle ABCD - Area of ΔABH - Area of ΔGHE - Area of square GECF - Area of ΔFGD.
Area = (8 × 8) - ([tex]\frac{1}{2}[/tex] × 8 × 2) - ([tex]\frac{1}{2}[/tex] × 2 × 4) - (2 × 2) - (([tex]\frac{1}{2}[/tex] × 6 × 2)
This is the first option.
As shown in the second figure,
Area of quadrilateral GFBE = Area of ΔGDF + Area of ΔBCF + Area of rectangle ABCD + Area of ΔABE
Area = ([tex]\frac{1}{2}[/tex] × 8 × 2) + ([tex]\frac{1}{2}[/tex] × 2 × 4) + (6 × 4) + ([tex]\frac{1}{2}[/tex] × 6 × 2)
This is the last option.
Hence the area of the quadrilateral can be either first or last option.

To measure the center, median is the best method.
What is median?The value that divides the mathematical numbers or expressions in half is known as the median. The middle data point is known as the median value.
To find the median:
First, organize the data points in ascending order before calculating the median.
The middle number on the list is the median if the number of observations is odd.
Take the value of the (n+1)/2-th term, where n is the total number of observations, to determine this.
Otherwise, the median is the simple average of the middle two figures if the number of observations is even.
Therefore, the median is the best method to find the measure of the center.

Equation to remember:
Length · Width · Height = Volume
LWH = V
-------------------------------------------------
In this word problem, you can find that we're missing the height aspect of the equation. Your equation would look something like this:
[tex]12 * 10 * h = 1800[/tex]
-------------------------------------------------
Work:
[tex]12 * 10 * h = 1800\\\\120h = 1800\\\\\frac{120h}{120} = \frac{1800}{120}\\\\h = 15[/tex]

A geologist visits 40 volcanoes in Alaska and California. 15% of the volcanoes are in California.
How many volcanoes does the geologist visit in California and how many in Alaska?
Answer:
Most explained:40% = 100%
15 = (100% - 15% = 85%) 85% in Alaska
California = 15% of 40 = (0.15 x 40) = 6
Alaska = 85% of 40 = (0.85 x 40) = 34
The simple way (or the way i found it simple):40 - 15 = 3415% of 40 = 6(I found the simple way after i solve the first way)

Write the absolute value equations in the form |x-b|=c (where b is a number and c can be either a number or an expression) that has the following solution set
all numbers such that x ≤ 5
all numbers such that x ≥ -1.3
Answer:
x - 5 ≤ 0, x + 13 ≥ 0
Step-by-step explanation:
All numbers such that x≤5.
x - 5 ≤ 0
All numbers such that x≥−1.3.
x + 13 ≥ 0
The absolute value equations in the form of |x-b|= c(where b is a number and c can be either a number or an expression) that has the following solution set
all numbers such that x ≤ 5 and all numbers such that x ≥ -1.3 will be x -5 ≤ 0 and x + 1.3 ≥ 0.
What is the absolute value equation?Isolate the absolute number on one side of the equation to solve an equation containing the absolute value.
Then, resolve both equations by changing their respective contents to the positive and negative values of the variable on the other side of the equation.
In another word, the absolute value equation is the equation that has a real absolute value not imaginary and not binary.
In the mode function, it could be two values if the mode is going negative or positive.
Given that the equation |x-b| = c and constraint is
all numbers such that x ≤ 5
all numbers such that x ≥ -1.3
so by substituting we will get x -5 ≤ 0 and x + 1.3 ≥ 0.

On a piece of paper, use a protractor to construct a triangle with angle measures of 50° and 40°.
Which statements about this triangle are true?
Select all correct answers.
The third angle measures 110°.
The third angle measures 50°.
Two sides have the same length.
The third angle measures 90°.
All sides have different lengths.
Answer:
the sentences that are true are..:
Two sides have the same length
The third angle measures 70°
It is an acute triangle.
i know that because eat triangle is 180°, so if we subtract 40° and 70° from 180°, we get 70°, meaning the three angles in the triangle are 40°, 70°, and 70°. Because all of the angles are under 90°, we know that it is an acute triangle.
The answers are (d) The third angle measures 90° and (e) All sides have different lengths.

5w–10>20 ; with the given set → {5,6,7,8}
its for an assignment
Answer:
w = 7, and w = 8 is correct
Step-by-step explanation:
1. Why 5 does not work
a. Substitute 5 into the equation
5w-10>20 --> 5(5) - 10 > 20
b. Solve the equation
Remember Pemdas:
P- Parentheses First
E- Exponents Second
M- Multiplication Third
D- Division Fourth
A- Addition Fifth
S- Subtraction Sixth
We are not working with Exponents and Parentheses, but we are working with the rest.
Since there is no P and E, that means that multiplication is first
5(5)-10>20 - 5(5) = 5 x 5 = 25
Now all is left is to subtract:
25 - 10 = 15
15 > 20 Is not true.
2. Why 6 does not work
a. Substitute
5w-10>20 --> 5(6) - 10 > 20
b. Solve
5(6) = 5 x 6 = 30
30 - 10= 20
20 > 20 is not true
Just like you are not greater than yourself, 20 can not be greater than its own self.
3. Why 7 and 8 work (7a, 7b is 7; 8a, 8b is 8)
7a. Substitute
5w-10>20 --> 5(7) - 10 > 20
8a. Substitute
5w - 10 >20 --> 5(8) - 10 > 20
7b. Multiply and subtract
5(7) = 5 x 7 = 35
35 - 10 = 25
25 > 20
25 is greater than 20
8b. Multiply
5(8) = 5 x 8 = 40
40 - 10 = 30
30 > 20
30 is greater than 20
Hereby, w = 7, and w = 8
Hope this helps
