Frederick used all his tiles to make a mosaic that was in the shape of a rhombus with a base of 10 inches and a height of 8 inches. Carrie has the same number of tiles as Frederick. She wants to use all of her tiles to make a mosaic in the shape of a parallelogram with a height of 5 inches. How long should she make the base of her mosaic?
Answer:
16 inStep-by-step explanation:
Both figures will have same area as same tiles used.
Area of rhombus:
A = ah = 10*8 = 80 in²Area of parallelogram:
a*5 = 80a = 80/5a = 16 inplz help! will mar brainliest.
Answer:
From -2<x<-1, the function F(X) is increasing. (B)
Really, it increases all from around -2.5<x<0.5
C is also the second answer, as it increases til around 2.5
It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.
Which means (B) is your answer.
If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.
Answer:
-2,5 < x < 1

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
Answer:
The area of the figure shown is 37.5cm^2, or 37 1/2cm^2, depending on what it wants from you.
Step-by-step explanation:
Break the shape into a triangle with measurements of 2.5, and 6.
And then the Rectangle with measurements of 6, and 5.
area of a rectangle is w*l so 6*5=30in
Area of a triangle is b*h*1/2 or b*h divided by 2 (either way both are the same, chose what makes you comfortable, I will use the first one.),
2.5*6*1/2
2.5*6=15
15*1/2=7 1/2cm or as a decimal 7.5cm
Now add the two for the full area, 30+7.5=37.5cm

Step by step plz on how to do this
Answer:
x=3
Step-by-step explanation:
Step 1: you have to replace y with x-6 to make it all one equation (as seen in the picture below)
Step 2: write it all together so: x-6= -2x+3
Step 3: add 2x on both sides to cancel out the negative so: x+ 2x and -2x+2x
Step 4: add 6 on both sides to cancel out the negative so: -6+ 6 and 3+6
Step 5: divide 3 by 3x and 9 to get x

Answer:
w=6
Step-by-step explanation:
First, we want to isolate the variable.
Add 6 on both sides
[tex]\frac{3w+5w}{2} =24[/tex]
Multiply both sides by 2.
3w+5w=48
Combine like terms.
8w=48
Divide both sides by 8.
w=6

Steve buys a wallet that costs $35.00. He pays 10% sales tax. How much does he pay for the wallet with tax?
A. $48.50
B. $38.50
C. $18.50
D. $45.50
Answer:
B. $38.50
Step-by-step explanation:
The original price of item (before tax) is 100% of the price of the item since 100% means the whole amount.
The tax is 10% of the original price, so add 10% to 100% making it 110%.
The total price including tax is 110% of the original price.
We need to find 110% of $35.00.
To find a percent of a number, multiply the percent by the number.
110% of $35.00 = 110% * $35.00
Change the percent to a decimal by moving the decimal point two places to the left.
110% becomes 1.10 as a decimal
110% of $35.00 = 110% * $35.00 = 1.10 * $35.00 = $38.50
Answer: B. $38.50

Answer:
Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth.

Answer: 12
Step-by-step explanation:
Find the difference between the first and second points.
Since the x-coordinates are the ones changing, find the difference between them.
2 - (-3)
= 5
Then find the distance between the second and the third points.
Here, the y coordinates are the only ones changing, so we subtract them/or find the distance between them.
2-(-5)
=7
Now add the distances (5+7) and you get 12.

The amounts of paper waste generated in a region during two years were 41,300,000 tons and 50,500,000 tons. What was the total paper waste generated over these two years in the region, expressed in scientific notation?
91.8 ⋅ 107 tons
91.8 ⋅ 1014 tons
9.18 ⋅ 1014 tons
9.18 ⋅ 107 tons
Answer: [tex]9.18 x 10[/tex]⁷[tex]tons[/tex]
Step-by-step explanation:
Given: The amounts of paper waste generated in a region during two years were 41,300,000 tons and 50,500,000 tons.
Then, the total paper waste generated over these two years in the region :-
[tex]41,300,000 + 50,500,000 = 91,800,000[/tex]
In scientific notation,
[tex]91,800,800 = 9.18 x 10[/tex]⁷
Hence, the total paper waste generated over these two years in the region =

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
Answer:
186 cm²
Step-by-step explanation:
*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.
*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.
Left rectangle:
A = lh
A = 12 (8)
A = 96 cm²
Right rectangle:
A = lh
A = 10 (9)
A = 90 cm²
Total:
A = 90 + 96
A = 186 cm²

= 8x+4 -3x
= 5x + 4
3.) 4(p-5) +3(p+1)
= 4p-20 + 3p+3
