Answer:
The 5 for $10 because its 2 dollars for a bag while the first is 3 dollars for a bag
Step-by-step explanation:
Answer:
I'm guessing the five for $10. If you were to by 5 for $3 it would be more than the five for $10. If there are 5 bags for $10 I'm assuming each bag is $2 which is lower than $3.

Answer:
B) 63 ft.
Step-by-step explanation:
To find how long it takes for a rotation, we need to find the circumference.
To do so, we use the formula 2(pi)r
To find the radius, we divide the diameter in half :
d = 20
r = d/2
r = 20 / 2
r = 10
Then, we plug that into the formula :
2(pi)10
Insert that into your calculator :
2(pi)10 = 62.83
Simplify :
62.83 = 63 ft.

Using PEDMAS rule, Value of the expression is 3 - 4 × 3 - 5 is -14.
What is PEDMAS rule?The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEDMAS: Parentheses, Exponents, Division and Multiplication(from left to right), Addition and Subtraction (from left to right).
3 - 4 × 3 - 5
= 3 - 12 - 5
= - 14
Hence, using PEDMAS rule, Value of the expression is 3 - 4 × 3 - 5 is -14.

Carmita bought 20 pizzas for a party, An hour after the party started, 2/7 of the pizzas had been eaten. How many pizzas had been eaten?
Answer: 5 5/7
Step-by-step explanation:
Number of pizza bought = 20
Fraction of pizza ate = 2/7
Therefore, the number of pizzas that have been eaten will be:
= Fraction of pizza eaten × Number of pizza bought
= 2/7 × 20
= 40/7
= 5 5/7
Therefore, 5 5/7 pizza have been eaten

If the perimeter of the polygon is 42, AB = ______?
Answer:
AB = 7
Step-by-step explanation:
The polygon pictured is a hexagon, which means that it has 6 equal side lengths. The perimeter is 42. AB is the length of one side.
Perimeter = 6 x length of one side
If you plug everything you know in the equation, you would get...
42 = 6 x length of one side
42 ÷ 6 = 7
So, 7 is the length of AB, since in a hexagon, all sides are the same length.
The length of side AB is 7.
What are regular polygons?A regular polygon is a closed shape that has straight sides of equal length and interior angles of equal measure.
This means that all of the sides and angles of a regular polygon are congruent (i.e., have the same size).
We have,
The given polygon is a hexagon since it has 6 faces.
Now,
The six faces are equal in length.
So,
6 faces length = 42
Now,
Each face = x
And,
6x = 42
x = 42/6
x = 7
Thus,
The length of AB is 7.

The radius of a circle is 2 meters. What is the circle's area?
(use 3.14 for π)
Answer:
it is approximately 12.57meters
Answer:
12.56 meters
Step-by-step explanation:
The area of a circle is πr², where r is the radius of the circle.
First we square the radius, which is 2. 2²=4.
Now our area is 4π.
Using 3.14 for π, we can say the area is 4 × 3.14, which is equal to 12.56

First step is finding an angle in the rightmost triangle (angle K)
Using TOA we have
Tan(x)=4/8
x=26.565
which means that 90-26.565= 63.4349 will give us angle K in regards to the left triangle
Using this we can solve for JM
Tan(63.4349)=x/8
8tan(63.4349=x
x=16
So if JM = 16
and LM=4
take their sum to find JL

Dustin has a spinner that is divided into 5 equal-size sections colored pink, blue, orange, white, and green. What is the probability that Dustin spins pink on the 1st spin and then spins a color other than pink on the 2nd spin?
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.

find the total surface area of the prism 10 2 6
Answer:
88 units
Step-by-step explanation:
First, we need to find the surface area of each side of the prism. Assuming this is a rectangular prism, judging by the dimensions, that makes things easier.
10*2=20
We'll multiply 20 by 2 since there are 2 sides with these dimensions, resulting in 40 units.
2*6=12
We'll multiply that by 4 since there are 4 sides with these dimensions, resulting in 48 units.
Adding 48 to 40, we get 88.
