Rectangle A measures 9 inches by 3 inches. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could be the dimensions of Rectangle B.
Answer:
3 inches by 1 inches or 6 inches by 2 inches. Both answera are correct
Step-by-step explanation:
just an equivalent ratio
The measurement pairs that could be the dimensions of Rectangle B are;
6in by 2in3in by 1inThe scaled copy of a shape is derived if the original figure is dilated by a constant
Given the measure of the sides of rectangle A:
Length = 9in
Width = 3in
Get the dilation factor
Dilation factor k = ratio of the sides
k = 9/3
k = 3
This means that rectangle B must also have the same scale factor as A.
The possible dimension pairs are 6in by 2in and 3in and 1in since the ratio of their sides is also 3;
k = 6/2 =3
k = 3/1 = 3

If a value of 80.4° is added to the data, how does the range change?
The range decreases to 46°.
The range stays 48°.
The range stays 49°.
The range increases to 50°.
Answer:
The Range Stays 48°.
Step-by-step explanation:\
Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.
Hope this helps!
Answer: B. The range stays 48
Step-by-step explanation:
The largest answer is 105 and the smallest answer is 57. The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest
Range = 105 - 57
Range = 48
The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.
So answer is B. The range stays 48
Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?

Answer: 76m
Step-by-step explanation:
First, start by splitting the figure into 2 smaller rectangular prisms; this can be done vertically or horizontally. I'll solve both ways so you can understand better.
Method 1: Splitting the figure into 2 rectangles vertically
The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the width (2m) by the length (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 5m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 5m (the height), and the answer is 40m.
Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 4m and you can figure out the width by subtracting 5m - 2m which gives you 3m. Now you know your base which is 4m. To solve for the height you must again subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 4 X 3 X 3. The volume of rectangular prism 2 should come out to be 36m.
The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 40m + 36m = 76m.
Method 2: Splitting the figure into 2 rectangles horizontally
The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the length (2m) by the width (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 2m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 2m (the height), and the answer is 16m.
Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 5m and the given width is 4m. Now you know your base which is 4m. To solve for the height you must subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 5 X 4 X 3. The volume of rectangular prism 2 should come out to be 60m.
The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 16m + 60m = 76m.
Hope this helps!

Susan has two dogs named Murphy and Fido. She feeds each of them the same type of dog food. Murphy eats 2/3 of a can of dog food each day. Fido eats 1/2 of a can of dog food each day. Each can of dog food costs $1.75. The pet store is offering a sale that allows customers to buy one can of food and get one free. Susan wants to buy a 60-day supply of dog food during the sale. To the nearest cent, what would be the cost of Susan's dog food purchase before tax?
Answer:
$61.25
Step-by-step explanation:
The quantity for a 60-day supply is 60 times the 1-day usage. The BOGO offer means the sale price is effectively half the usual price.
__
One day supply: 2/3 can + 1/2 can = (4/6 +3/6) = 7/6 can
60-day supply: 60 × 7/6 can = 70 cans
Susan will be paying for 70/2 = 35 cans of dog food. (She will get 35 cans free.) So, her cost will be ...
35 × $1.75 = $61.25
The cost of Susan's dog food purchase would be $61.25 before tax.

Answer:
\(\huge\boxed{\sf x =28 \textdegree}\)
Step-by-step explanation:
Given that,
∠IAK = 62°
∠IAK + ∠IAD = 90° (Complementary angles)
62 + ∠IAD = 90°
Subtract 62 to both sides
∠IAD = 90 - 62
∠IAD = 28°∠IAD = ∠ACB (Corresponding angles are equal)
So,
∠ACB = 28°∠ACB = ∠GCJ (Vertically opposite angles are equal)
So,
28° = x°
OR
x° = 28°\(\rule[225]{225}{2}\)
Answer:
28 degrees
Step-by-step explanation:
If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.
--> Angle LAJ is 62 degrees
If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.
We know that in a triangle, there are three angles, and the angle measures combined equals 180.
Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.
--> 180 - 90 - 62 = 28
--> Angle BCA = 28 degrees
Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.
Angle x = 28 degrees

Answer:
$12.31
Step-by-step explanation:
Think of the original rate of pay as being 100%.
If your rate is increasing by 7%, it will now be 107% of the original rate (since 100% + 7% = 107%)
To find 107% of $11.50, convert 107% into a decimal
⇒ 107% = 107/100 = 1.07
then multiply this by the original rate to get the new increased rate:
⇒ $11.50 × 1.07 = $12.305
Rounding this to the nearest hundred = $12.31
Alternatively, you can find 7% of $11.50 and then add this to $11.50.
⇒ 7% = 7/100 = 0.07
Therefore, 7% of $11.50 = 0.07 × $11.50 = $0.805
Add this to the original rate:
$11.50 + $0.805 = $12.305
Rounding this to the nearest hundred = $12.31

The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
