[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
9.45
To round up to nearest whole number, we have to see the tenth place.
If the value of the tenth place is greater or equal to 5, then we round up the number to 10. If the value of the tenth place is less than 5, the we round up the number to 9.
The value of the tenth place is 4, which is less than 5, we will round up the number to 9.
[tex]\rule[225]{225}{2}[/tex]
9.45 rounded to the nearest whole number is 9.
Given that a decimal number 9.45 we need to round it to the nearest whole number,
To round a decimal number to the nearest whole number, you need to look at the digit immediately to the right of the decimal point.
In the case of 9.45, the digit to the right of the decimal point is 4. If this digit is less than 5, you simply remove all the digits after the decimal point and keep the whole number as it is.
However, if the digit to the right of the decimal point is 5 or greater, you increase the whole number by 1.
To round 9.45 to the nearest whole number, we examine the decimal part of the number, which is 0.45.
If the decimal part is less than 0.5, we round down to the nearest whole number. In this case, since 0.45 is less than 0.5, we round down.
Therefore, 9.45 rounded to the nearest whole number is 9.

find the area of the shape below
Answer:
The figure is a composite shape.
Theres 1 triangle and 1 rectangle
The formula to find the area of the triangle is 1/2 x base x height
1/2 x 7 x 3 = 10.5 units^2
The formula to find the area of the rectangle is base x height
7 x 3 = 21 units^2
Then add up all the areas to find the area of the entire shape.
10.5 units^2 + 21 units^2 = 31.5 units^2

Julie needs to cut 4 pieces of yam, each with the same length, and a piece of yarn 7.75 inches long. Let x represent the
length of each of the equal pieces of yarn that Julie decides to cut. What is the equation that can be used to determine the
total length of all of the yarn that she ends up cutting, y is the graph of the equation continuous or discrete?
Answer:
She has to cut another piece = 7.75 inches
Total length = 4x + 7.75
This is what y represent, so
y = 4x + 7.75
The graph of the equation is continuous
The data set below shows prices for concert tickets in 10 major cities. Find the interquartile range (IQR) of the set. How do the middle 50% of the prices vary?
Answer: IQR = 16
Step-by-step explanation:
Given the following data:
Cost of concert :
CITY : Q, R, S, T, U, V, W, X, Y, Z
Price : 35,36,42,38, 24,29,25, 44,49, 26
Interquartile range (IQR) = Q3 - Q1
Where,
Q3 = the upper quartile
Q1 = lower quartile
Rearranging the data:
24,25,26,29,35,36,38,42,44,49
Q3 = 42
Q1 = 26
IQR = (42 - 26) = 16

Priya asked each of five friends to attempt to throw a ball in a trash can until they succeeded. She recorded the number of unsuccessful attempts made by each friend as: 1, 8, 6, 2, 4. Priya made a mistake: The 8 in the data set should have been 18. How would changing the 8 to 18 affect the mean and median of the data set
Answer: The mean will increase and the median would not change
Step-by-step explanation:
Recorded data by Priya :
Data: 1,8,6,2,4
Mean of data = (1+8+6+2+4)/5
=21/5 = 4.2
Median of data = 1,2,4,6,8
Median = 4
Correct data: 1,18,6,2,4
Mean of data = (1+18+6+2+4)/5
=31/5 = 6.2
Median of data = 1,2,4,6,18
Median = 4
Therefore ; according to the evaluation above, the median will remain unchanged, but the mean increased from 4.20 to 6.20.

Find the area of the shape below
Answer:
32 units^2
Step-by-step explanation:
This is a trapezoid
The area of a trapezoid is found by
A = 1/2 (b1+b2) h
A = 1/2 ( 4+12) *4
A = 1/2 (16) *4
A =32
Answer:
I think the answer is 32.!
Step-by-step explanation:
Anyone please correct me if I'm wrong.
I would divide the 12 into 3 to get 4 for the 3 parts.
I will start with the triangle on the left 4 times 4=16. Divide it 1/2, which you get 8.
On the triangle on the right is the same, so 8.
The middle is 4 times 4=16.
Last 8+8+16=32.
I think the answer is 32 units.!

Answer:
ry-axis(x, y) → (–x, y)
rx-axis(x, y) → (x, –y)
Step-by-step explanation:
When you reflect over the x axis, the y values change. When you reflect over the y axis, the x values change.

Dorinda worked 2 part- time jobs and earned $234.50 for working a total of 30 hours at both jobs. She is paid $7.50 per hour at Job A and $8.00 per hour at Job B. How many hours did Dorinda work at Job A?
Answer:
Dorinda worked at Job A for 11 hours
Step-by-step explanation:
Step one
This is a word that leads to simultaneous.
Let us begin by modeling the system of equation from the problem
Let x and y be the number of hours worked in both jobs A and B respectively
Step two
x+y=30---------1
7.5x+8y=234.50----2
Solving the equations simultaneously we have
1. Multiplying equation 1 by 8 and equation 2 by 1 and subtracting from equation 2 to find y
8x+8y=240---------1
- 7.5x+8y=234.50----2
=0.5x=5.5
x=5.5/0.5
x= 11hrs
Substituting x=11 in equation 1 we can find y
11+y=30
y= 30-11
y= 19hrs

You estimate that there are 64 marbles in a jar. The actual amount is 46 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.
Answer:
percentage error = 39.1%
Step-by-step explanation:
You estimate that there are 64 marbles in a jar. The actual amount is 46 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.
Given that You estimate that there are 64 marbles in a jar.
The actual amount is 46 marbles
Actual marbles = 46
Your estimate = 64
[tex]\% error =\frac{estimated - actual}{actual}[/tex]
% error = | estimate - actual | / actual × 100%
estimate amount - actual amount = 64 - 46 = 18
[tex]= \frac{18}{46} \times 100\\\\=0.391\times 100\\\\=39.1 \%[/tex]
Therefore, percentage error = 39.1%
A Roth IRA is advertised to pay 1.5% annual interest. You researched the rate of inflation to be 1.15% this year. What is the actual or real rate of return on the IRA?
Answer: 0.35%
Step-by-step explanation:
Given the following :
Advertised interest rate = nominal rate = 1.5%
Inflation rate = 1.15%
The real rate of return is calculated by:
[(1 + nominal rate) / ( 1 + inflation rate)] - 1
[(1 + (1.5/100)) / (1 + (1.15/100))] - 1
[(1 + 0.015) / ( 1 + 0.0115)] - 1
[ 1.015 / 1.0115] - 1
1.0034602 - 1 = 0.0034602
Real rate of return = (0.0034602 * 100)%
Real rate of return = 0.346%
Answer: 0.35%

What transformations would result in the image shown? (question for the first image)
a.Δ ABC is reflected over both axes.
b.Δ ABC is reflected over the y-axis and translated down 5 units.
c.Δ ABC is reflected over the x-axis and translated right 5 units.
d.Δ ABC is translated right 5 units and down 5 units.
Which transformations would result in the image shown?
a.ABCD is reflected over both axes.
b.ABCD is translated right 4 units and down 3 units.
c.ABCD is reflected over the x-axis and translated right 4 units.
d.ABCD is reflected over the y-axis and translated down 3 units.
Answer: For the first image, D will be the correct answer. For the second image, A will be the correct answer.
Step-by-step explanation:
The first image has a quite simple answer because translating the shape just means moving every point in the direction given according to some many units. In this case, we would be translating points A(-4,3), B(-3,1), and C(-1,2) 5 units right and 5 units down to get us the prime points of A'(1,-2), B'(2,-4), C'(4,-3).
In the second image, a reflection just describes a flip over some line, known as the line of reflection. We change the point's signs depending on the line of symmetry we are given when reflecting (in this case, the y axis). Reflecting the trapezoid over the y axis will result in a change of signs of the x values of the given points. Point A of the trapezoid is located on coordinate (-2,2), after the reflection, it will be located on point (2,2). Points B will reflect from point (-1,2) to point (1,2). Point C will reflect from (-1,1) to (1,1). Finally, point D will reflect from point (-3,1) to (3,1). After this reflection, we have to perform the same one except only the y values of our coordinates will change because we are reflecting over the x axis. After you graph the trapezoid from the previous reflection, do the same thing by just changing the y values of the coordinates to get your desired image.
Answer:
D
A
Hope this helps!
