Kevin needs 2/3 of a yard to make a pillow. he has 3 1/3 yards of fabric. How many pillows can he make?
Answer:
5 pillows
Step-by-step explanation:
3 1/3 also = 10/3
10/2 = 5
5/1 · 2/3 = 10/3
10/3 = 3 1/3
Answer:
5 pillows
Step-by-step explanation:
Divide the total amount of yards by the number of yards to make a pillow to get the number of pillows Kevin can make.
[tex]3 \frac{1}{3} /\frac{2}{3} =\frac{10}{3} /\frac{2}{3} =\frac{10}{3}*\frac{3}{2} =\frac{30}{6} =5[/tex]
There are 10 10 balls total of which 2 2 balls are purple. Leslie picks a ball at random, puts it back and picks a second ball at random. Find the probability of first picking a purple ball and then again a purple ball on the second draw.
Answer: 1/25
Step-by-step explanation:
Number of balls = 10
Number of purple balls = 2
Since it's probability with replacement,
Probability of picking a purple ball the first time = 2/10 = 1/5
Probability of picking a purple ball the second time = 2/10 = 1/5
Therefore, the probability of picking a purple ball both times will be:
= 1/5 × 1/5
= 1/25
Amy has a piece of wood that measures 42 inches. The model shows the length remaining after she cut a piece from the 42-inch piece of wood. About how many inches did Amy cut from the 42-inch piece of wood?
Answer:
She has 42 pieces of wood each of 1 inch of length.
Step-by-step explanation:
Amy has 42 inches piece of wood.
She has to cut an inch.
After cutting pieces of inch each she counts the pieces to be 42.
Mathematically
Total length / unit lenght = Number of pieces
42 inches/ 1 inch= 42 pieces.
She has 42 pieces of wood each of 1 inch of length.

Which equation describes the circle
with center (5,-1) and radius 7?
A (x - 5)' + (y +1)* = 7
B (x - 5)* + (y + 1)* = 49
(x + 5) * + (y - 1) = 7
D(x + 5)' + (y - 1)' = 49
Answer:
B. (x-5)²+(y+1)² = 49
Step-by-step explanation:
An equation of a circle with center (h, k) and radius r is
[tex] \large \boxed{ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} }[/tex]
We have all given information we need. Our h is 5 - Our k is -1 and our radius is 7
Substitute these values in
[tex] \large{ {(x - 5)}^{2} + {(y - ( - 1))}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = 49 }[/tex]
So the answer is B choice.
The diagram shows a pyramid with a rectangular base. The volume of the pyramid is 108cm^3.
What is the length of the base edge labeled x?
1. 2cm
2. 6cm
3. 18cm
4. 30cm
Answer:
Solution given:
Volume of pyramid=108cm³
area of base*height=108cm²
6*x*3=108
x=108/18
x=6
option2:6cm

Step-by-step explanation:
Given:
2,1,4,3,6,5,8,___
Pairing the sequence in twos
2,1
4,3
6,5
It can be seen that each pair of the sequence is arranged in descending order (from highest to lowest)
1, 2 is written as 2,1
3, 4 is written as 4,3
5, 6 is written as 6, 5
Then the next two numbers
7, 8 will be written as 8,7
2,1,4,3,6,5,8,7
4. Solve 18 (c – 19) = 108. Show your steps
Answer:
c = 25
Step-by-step explanation:
First, you can divide by 18 on both sides:
18 (c - 19) = 108
÷ 18 ÷18
c - 19 = 6
To isolate the variable c, you can add 19 on both sides:
c - 19 = 6
+19 +19
c = 25
Answer:
c= 25
Step-by-step explanation:
108/18 = 6
6 +19 = 25

A rectangular box has a base measuring a by a meters and height of b meters.
Which of the following represents the surface area of the box?
Answer:
2a(a+2b) square metres
Step-by-step explanation:
surface area of a box = 2(lw+wh+lh)
l is the length = a metres
w is the width = a mtres
h is the height = b metres
Substitute into the formula
surface area of a box = 2(a*a+ab+ab)
surface area of a box = 2(a² + 2ab)
surface area of a box = 2a(a+2b) square metres
This give sthe surface area of the box

Two expressions are shown below:
1. 514÷23
2. 514×32
Without solving these expressions, determine if they are equivalent. How do you know? (Please help..)
Answer:
Clearly they are not equivalent because division will get you a smaller number ( except when decimals are in used or special cases ) as an answer and division times the number that will oppositely get you a bigger number ( again, except the decimal or special cases )

The circle below has a radius of 10 inches. Find the area of Sector A and Sector C
Answer:
area of sector A = 47.97 in²
area of sector C = 109.03 in²
Step-by-step explanation:
area of full circle = πr² = (3.14)(10²) = 314 in²
area of sector A = (55/360)(314) = 47.97 in²
area of sector C = (314/2) - 47.97 = 109.03 in²
