Answer:
D. 10.3%
Step-by-step explanation:
Find the percent error using the formula:
percent error = | (observed - expected) / expected | x 100
32 is the observed value, and 29 is the expected value
Plug in these values to solve for the percent error:
percent error = | (observed - expected) / expected | x 100
percent error = | (32 - 29) / 29 | x 100
percent error = 10.3%
So, the correct answer is D. 10.3%
Can someone please help me with 2 math questions.
1. A TV is on sale for $399, or 16% off. What was the original price of the TV? Show your work.
2. A computer is on sale for $450.50, or 15% off. What was the original price of the computer? Show your work.
Answer:
Step-by-step explanation:
1) $399 = 84% of the original amount
Divide both sides by 84 to get what one percent would be
$4.75 = 1%
Then multiply both sides to get one hundred percent [the original price]
$475 =100%
Use this method to do the second question
$450.50 = 85%
Divide by 85
$5.30 = 1%
Multiply by 100
$530 = original price

Which situation can best be modeled with an exponential function? A.The value of a car depreciating 6% each year. B.The cost to purchase different weights of bananas at a store. C.The total number of miles run by a person who runs 8 miles per day. D.The amount of money a salesperson makes if they make a salary plus 3% commission on total sales for the week.
Answer:
A.The value of a car depreciating 6% each year.
Step-by-step explanation:
According to definitions.net "The exponential function is used to model a relationship in which a constant change in the independent variable gives the same proportional change in the dependent variable."
Given that the car depereciate by 6% each year, I can write;
Let the initial value of the car be P
Let the value of the car at time t be Y
Let the number of years be t
This is a case of exponential decay so;
Y = P( 1 - 6/100)^t

Which of the following represents “three times the abscissa decreased by the ordinate is twenty-two”?
3 x = 22 - y
y - 3 x = 22
3 x - y = 22
Answer:
3x - y = 22
Step-by-step explanation:
The abcisssa is known as the x coordinate while the ordinate is the y coordinate
abcissa = x
ordinate = y
“three times the abscissa = 3x
“three times the abscissa decreased by ordinate is expressed as;
3x - y
Is the result is 22, hence;
3x - y = 22
this gives the required expression
The ounces of yellow paint, y, needed to mix with x ounces of blue paint to make a certain shade of green paint can be represented by the equation y = 1.5x. What is the constant of proportionality of the equation? Calculator
Answer:
Step-by-step explanation:
A proportional constant satisfies
y/x=k, where k is the constant of proportion
Since
y/x=k
y=kx
You are given
y=1.5x so
k=1.5

Javier and his family drink 3 gallons of milk each week. Javier drinks 5 quarts of milk each week. How many pints of milk does the rest of his family drink during the week?
A.12
B.14
C.7
D.10
Answer:
So basically Javier and his family drink a total of 12 quarts of milk each week because 1 gallon of milk is 4 quarts so Javier drinks 5 quarts 12-5=7
which leaves 7 quarts for his family. 2 pints are equal to a quart therefore 14 pints are left for his family

HELP WHAT IS THE AREA OF THE COMPOSITE FIGURE
Answer:
[tex]76 ft^3[/tex]
Step-by-step explanation:
First, split the figure into two different rectangular prisms. I found it easiest to split it like this (image attached below).
To find the volume of the lower prism, multiply the Length (6ft) x Width (2ft) x Height (3ft).
6 * 2 * 3 = 36 [tex]ft^3[/tex]
Next, subtract 3 from 8 to get the height of the top prism. 8 - 3 = 5, so the height of the top prism is 5.
Multiply the Length (4ft) x Width (2ft) x Height (5ft).
4 * 2 * 5 = 40 ft[tex]^3[/tex]
Add the two volumes.
40 + 36 = 76 ft^3.
Final answer: [tex]76 ft^3[/tex]

The area of a square is represented by the expression 16x^4y^8. What is the length of each side of this square
Answer: [tex]4x^2y^4[/tex]
Step-by-step explanation:
Given
The area of the square is [tex]A=16x^4y^8[/tex]
Suppose a is the side length of the square
The area of the square is given by
[tex]\Rightarrow A=(\text{side length})^2[/tex]
So, we can write
[tex]\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4[/tex]
length of each side is [tex]4x^2y^4[/tex]
Find the volume of the cylinder find volume of a cylinder with the same radius and double the height what is the volume of the cylinder
Answer:
1004.8^3
Step-by-step explanation:
to find the volume you must first get the area of the base
3.14 x 8 squared or 8^2 which will equal 200.96
then you multiply the base times height
200.96^2 x 5 = 1004.8 cubed or 1004.8^3
also be careful you don't multiply 200.96 twice because it is squared (;

Mrs. Anderson is building a model for a pool. The actual pool is 32 yards long and 28 yards wide. If the scale factor is 0.5 inch = 2 yards, find the length of Mrs. Anderson's model pool.
2 yards = 0.5 inch
32 yards = x
I need some help. Can someone assist me with this?
Answer:
x = 12
WN = 28
Step-by-step explanation:
SO = WN and SO = 2WI
3x - 8 = 2(x + 2)
3x - 8 = 2x + 4
3x - 2x = 4 + 8
x = 12 now replace x with 12 in the first equation given
3x - 8 = 3×12 - 8
36 - 8 = 28

Need help with the correct answer please! Thank you. Which two triangles are congruent by the SSS Theorem? I picked D but that is the wrong answer.
Answer:
B
Step-by-step explanation:
RQ=TV
QS=VU
RS=TU
While proving that 2 triangles are congruent you have to consider the same side for both triangles.
The mistake you made was that you presumed that since both have equal sides they are equal,
In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.
B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched
