Trey bought 3 and 3 fourths pounds of apples from the grocery store. Corinne bought 1 and 1 third pounds of grapes from the grocery store. How many more pounds of fruit did Trey buy
Answer: 2 5/12
Step-by-step explanation:
Trey bought 3¾ pounds of apples from the grocery store. Corinne bought 1⅓ pounds of grapes from the grocery store.
To know how many more pounds of fruit that Trey bought, we have to find the difference between the value given above and this will be:
= 3¾ - 1⅓
= 3 9/12 - 1 4/12
= 2 5/12
Trey bought 2 5/12 pounds more.
1. Annette scored 85. 73. and 94 on her first three quizzes. How high does she need to
score on her fourth quiz to keep her quiz average at at least a B (8046) ?
Answer:
at least a score of 68
Step-by-step explanation:
(85+73+94+q)/4 ≥ 80
(252 + q)/4 ≥ 80
multiply each side by 4 to get:
252 + q ≥ 320
q ≥ 68

Answer:
773.8 inch²
Step-by-step explanation:
Find the surface area at first
the top and bottom = 6²π = 36π
around is circumference x by height = 12π x 15 = 180 π
multiply these by 3/4
top = 27π
bottom = 27π
around = 135π
add the two rectangles = 180 inch²
Total = 773.8

1 Serek is showing how to model the area
formula of a triangle
1) Original triangle
2) Create a congruent triangle.
Rotate it then join it to the original
triangle, forming a parallelogram.
3) Decompose the parallelogram
into a right triangle and a trapezoid.
4) Rearrange the triangle and
trapezoid to form a rectangle.
Which of these steps will identify the area
of the original triangle?
A Find the total area of the trapezoid
B Find half the area of the rectangle
C Find half the area of the trapezoid
D Find the area of the shaded triangle
5.80
Answer:
Find half the area of the rectangle
Step-by-step explanation:
Given
See attachment for the Serek's steps
Required
Which can be used to determine the area of the original triangle
To do this, we simply analyze each step.
At step 2, where he joined two congruent triangles to form a parallelogram.
Half the area of the parallelogram will give the area of the original triangle (since both triangles are equal)
At step 3, where he decomposed the parallelogram to a trapezoid and a right triangle.
Half the sum of the areas of the resulting shapes (trapezoid and right triangle) will equal to the area of the original triangle but half the area of each shape will not amount to the area of the original triangle
At step 4, where the right triangle and the trapezoid are merged to form a rectangle.
The area of the rectangle will equal to the area of the parallelogram in step (2).
So, half the area of the rectangle will equal to the area of the triangle.
Hence, (b) is correct

Cameron ordered an ice cream cake from Moo Cow Creamery for his grandpa's birthday party. The cake was packed in a
cylindrical-shaped box. The dimensions of the box are shown in the diagram.
8 in.
24 in.
Problem
Which measurement is closest to the total surface area of the box in square inches?
A
603.19 in 2
B
1,507.96 in.
С
3,619.11 in 2
D
4,825.49 in.
Answer:
The measurement that is closest to the total surface area of the box is 1,507.96 [tex]in^2[/tex].
Step-by-step explanation:
The surface area of the cylinder can be found by adding the area of the two bases and the side, which is [tex]12^2\pi *2+ 24\pi *8 = 144\pi * 2+192\pi = 288\pi + 192\pi = 480\pi[/tex] ≈ 1507.96, so the correct answer is choice B.

Mr. Hawkins is covering a wall with wallpaper. The room measures 14 feet by 12 feet in a rectangular shape. Each square foot or wallpaper costs $2.90. What is the cost of adding wallpaper to the room?
Answer:
The total cost of adding wallpaper to the room is 487.20
Answer:
The total cost of adding wallpaper to the room is $487.20
Step-by-step explanation:
Basically, how I got the answer is:
1. The shorter sides of the rectangle are 12 and the longer sides are 14.
2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.
3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.
Hope this helps! :)

Answer:
D. 8.8
Step-by-step explanation:
As the pythagorean theorem.
A² + B² = C²,
5.4 × 5.4 + 7 × 7 = C²,
29.16 + 49 = C²,
78.16 = C²,
8.8 ≈ C

find the midpoint between two points on a coordinate plane whose coordinates are (5,7) and (-3,1)
Step-by-step explanation:
Mid point formula ,
x = (x1+x2)/2 , y = (y1+y2)/2
x = 1 , y = 4
therefore ,midpoint is (x, y)= (1,4)
(1,4) all u gotta do is 5+-3 ÷2 to find x and 7+1÷2 to find y and booom u got your answer
Evaluate the equation: e - 3.1 = 5
A. e = 1.9
B. e = 2.1
C. e = 8.1
D. e = 8.5
Answer:
C. e = 8.1
Step-by-step explanation:
e-3.1= 5
e = 5+3.1
e = 8.1
What is the value of a in the equation 0.75 (a - 2) = 5.25
Answer:
a must be 9
Step-by-step explanation:
Divide both sides of the given equation by 0.75, to isolate (a - 2):
a - 2 = 5.25/0.75 = 7
Then a - 2 = 7, and so a must be 9.
Is -2 rational or irrational?
Answer:
Rational
Step-by-step explanation:
Rational. It can be expressed as a fraction, which is the definition of a rational number.
Hope this Helps!
-2 is rational
This is because every negative integer is a negative rational number.
We know that -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….
In other words, any negative integer n can be written as n = n/1, here n is negative and 1 is positive.
So, negative 2 is rational.
