What is the value of 95 - 10 + +2(141 - 7)?
Answer:
353
Step-by-step explanation:
95 - 10 + 2(141 - 7)
following PEMDAS we will do parenthesis first
95 - 10 + 2(134)
multiplication is next
95 - 10 + 268
addition and subtraction are interchangeable when using PEMDAS but you do whatever comes first. since it's subtraction first in this equation we will do 95 - 10.
85 + 268
now we are left with addition
85 + 268 = 353

Answer:
The area of the composite shape is:
122.50 [tex]cm^{2}[/tex]Step-by-step explanation:
To find the area of composite shapes you can pull apart this in known shapes, in this case, a rectangle and a triangle. Taking into account this, we can find the rectangle area firstly:
Rectangle area = base * heightThe base of the rectangle is the measure from down (14 cm) and the height is the measure in the left side (7 cm), with these values we can replace the formula:
Rectangle area = base * heightRectangle area = 14 cm * 7 cmRectangle area = 98 [tex]cm^{2}[/tex]Now, to calculate the area of the remaining triangle, we must use the next formula:
Triangle area = [tex]\frac{base*height}{2}[/tex]Where the base would be equal to the left side of the shape (7 cm) and the height is the difference between the measurement in the top side and the measurement in the bottom side:
Height of the triangle = top side - bottom sideHeight of the triangle = 21 cm - 14 cmHeight of the triangle = 7 cmWe can replace in the formula:
Triangle area = [tex]\frac{7 cm * 7cm}{2}[/tex]Triangle area =[tex]\frac{49cm^{2} }{2}[/tex]Triangle area = 24.5 [tex]cm^{2}[/tex]By last, we must add the two values of the areas obtained:
Area of the composite shape = rectangle area + triangle area.Area of the composite shape = 98 [tex]cm^{2}[/tex] + 24.5 [tex]cm^{2}[/tex]Area of the composite shape = 122.5 [tex]cm^{2}[/tex]Whats a equivalent expression to (3x^2+3)+(-2x^2+7)

3) 12ac^14/b^3
4) 9ac^7/b^5
Answer:

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First of all we can simplify the the first therm because a property of power says that we can simplify a power of power by multiply the exponents
a^4b^8c^2
For the same property 2c^5 becomes 8c^15
now we have
(a^4b^8c^2)(6a^3b)(8c^15)/4a^6b^12c^3
if we simplify the numbers we can obtain
(a^4b^8c^2)(6a^3b)(2c^15)/a^6b^12c^3
If we simplify the parameters we can obtain
12ac^14/b^3
Find the total amount given the original price and tip rate. Round to the nearest cent if necessary. Original price: $41.32 Tip: 15%
Answer:
$6.20
Step-by-step explanation:
We can covert 15% to a decimal by moving the decimal point two places over.
15% = 0.15
41.32 X 0.15 = 6.198
6.198 ≈ $6.20
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price: $41.32
Tip: 15%
Now,
The amount of the tip.
= 15% of 41.32
= 15/100 x 41.32
= $6.189
The total amount.
= Original price + Tip amount
= 41.32 + 6.189
= $47.509
Thus,
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509

On Monday, 30% of the 900 students at Maple Middle school walk to school. Complete the double numberline model. How many students walk to school on Monday?
the answer is 270 (dont click ant links in this app)
270 students walk to school on Monday.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Total students= 900
Percent of student who walk to school= 30%
So, the number of students walk to school on Monday
= 30% of 900
= 30/100 x 900
= 30 x 9
= 270
Hence, 270 students walk to school on Monday.

Answer:
A fraction is a number consisting of one or more equal parts of a unit. It is denoted by the symbol a/b, where a and b≠0 are integers (cf. Integer). The numerator a of a/b denotes the number of parts taken of the unit; this is divided by the number of parts equal to the number appearing as the denominator b.
