Sandy bought a soft drink for 2 dollars and 5 candy bars. She spent a total of $12. How much did each candy bar cost?
Answer:
If Sandy bought a soft drink for 2 dollars that's 2 dollars subtracted from the total of $12.00 spent
If we have 10 dollars and bought 5 candy bars we would divide so 10 divided by 5 = 2 so each candy bar costed $2 dollars

There is a stack of 10 cards, each given a different number from 1 to 10. Suppose we select a card randomly from the stack, replace it, and then randomly
select another card. What is the probability that the first card is an even number and the second card is less than 3?
Write your answer as a fraction in simplest form.
Answer:
1/10.
Step-by-step explanation:
The probability of getting an even card out of 10 cards numbered 1 - 10 is 1/2. The even numbers available are 2, 4, 6, 8, and 10 while the odd ones available are 1, 3, 5, 7, and 9. So half the outcomes could come out even.
The probability the second card is less than two is 1/5 (2/10 simplified). Since there are 10 cards with numbers 1-10, only two cards will have numbers less than 3, 1 and 2.
To find the total probability, multiply the two. (1/2) * (1/5) = 1/10. There is a 1 out of 10 chance that the first card is even and the second card is less than 3.
What the volume of a cylinder with a diameter of 6mm and a height of 7 mm.it says it’s 700 something but the only answers on the test are as low as 100 and highest is 230? Help plz
8th grade math*
Answer: 197.82mm³
Step-by-step explanation:
Volume of a cylinder = πr²h
where,
π = 3.14
r = Diameter/2 = 6mm/2 = 3mm
h = 7mm
Volume = πr²h
= 3.14 × 3² × 7
= 3.14 × 9 × 7
= 197.82mm³
The volume of the cylinder is 197.82mm³
Two angles are vertical angles. If one of the angles measures 35º and the other measures (4x+3)º, which algebraic equation can be used to solve for the value of x?
35 + 4x + 3 = 180
35 + 4x + 3 = 90
35 = 4x + 3
None of these are correct
4x + 3 = 90
35 = 4x+3
If they're vertical then they're worth the same or equal. So 4x+3 is equal to 35 and then you solve for x from there.

Find the area of the rectangle on this centimetre grid.
Answer:
Step-by-step explanation:
I think this question is not clear.
If you could explain/upload the centimeter grid it'd be explain.
But generally, what you should do is: calculate the number of centimeters on the longer side (length (l)) and note that, now calculate the number of centimeters on the shorter side (breadth(b)).
Use the formula, Area of a rectangle = l×b to solve your math problem

Answer:
56°
Step-by-step explanation:
180 = 40 + (2x) + (3x)
180 - 40 = 40 + 5x - 40
140/5 = 5x/5
x = 28
2(28)
= 56
Answer:
m∠A = 56°
Step-by-step explanation:
A triangle contains 180°. So
180 - 40 = 140
2x + 3x = 140
5x = 140
x = 28
Now, plug in the value for x.
2(28) = 56

A 16-inch diameter (8-inch radius) car tire is one of the most popular sizes for today's car Find the number of revolutions made by a tire with a radius of 8
inches that travels 5,280 feet (or 1 mile). Use 3.14 for Round your answer to the nearest tenth of a revolution.
Answer:
1261.1 revolutions
Step-by-step explanation:
Given
[tex]d = 16in[/tex] --- the diameter
[tex]Distance = 5280ft[/tex]
Required
The number of revolution completer
First, calculate the circumference (c) of the tire
[tex]c = \pi d[/tex]
[tex]c = 3.14 * 16[/tex]
[tex]c = 50.24[/tex]
Let the number of revolutions be n.
The product of n and the circumference equals to the total distance travelled.
So:
[tex]c * n = 5280 ft[/tex]
[tex]50.24in* n = 5280 ft[/tex]
Make n the subject
[tex]n = \frac{5280 ft}{50.24in}[/tex]
Convert feet to inch
[tex]n = \frac{5280 *12in}{50.24in}[/tex]
[tex]n = \frac{63360in}{50.24in}[/tex]
[tex]n = \frac{63360}{50.24}[/tex]
Solve for n
[tex]n = 1261.14649682[/tex]
Approximate
[tex]n = 1261.1[/tex]

if there is 2 catfish in a tank, in order to reach 6 catfish, we need 3 tanks
therefore, 3*3=9, 9 is the amount of angel fish
6+9=15
you have 11 art projects that weigh 24 pounds. If you give you mom 7 of your art projects, how much would her box weigh?
The weight for mom's boxes is obtained as 41.41 pounds.
What is weight?
Weight gauges how much gravity is pulling on a body.
The weight formula is provided by -
w = mg
Since weight is a force, it has the same SI unit as a force, which is the Newton (N).
Use a proportion to solve this problem.
Since the weight of the art projects is directly proportional to the number of art projects, we can set up the following proportion -
weight of 11 art projects / 11 = total weight / 24
Solving for the total weight -
total weight = (weight of 11 art projects / 11) x 24
total weight = 2.18 x 24
total weight = 52.32 pounds
So the total weight of the 11 art projects is 24 pounds, and if mom gets 7 of them, 4 art projects will be left weighing a total of -
weight of 4 art projects = (weight of 11 art projects - weight of 7 art projects)
weight of 4 art projects = (24 - (7/11) x 24)
weight of 4 art projects = 10.91 pounds
So, mom would be receiving 7 art projects weighing a total of -
weight of 7 art projects = (total weight - weight of 4 art projects)
weight of 7 art projects = (52.32 - 10.91)
weight of 7 art projects = 41.41 pounds
Therefore, mom's box would weigh 41.41 pounds.

If the mean of A and B is 20 , the mean of B and C and the mean of A,B and C us 18 . What is the mwan of A and C
Answer:
the mean of A and C is 10
Step-by-step explanation:
Given that
The mean of A and B is 20
The mean of B and C is 24
And, the mean of A, B and C is 18
We need to find out the mean of A and C
Since the mean of A and B is 20
So, a + b = 20 × 2
= 40
Likewise for B and C it is 48
And, for A, B and C, it is 54
So,
a + b = 40
b + c = 48
a + b + c = 54
So if we put the value of b + c in the above equation
a + 48 = 54
a = 6
b = 34
c = 14
Now the mean of the A and C is
= (6 + 14) ÷ 2
= 10
Hence, the mean of A and C is 10

Answer:
-45[tex]x^{2}[/tex]-26x+30
Step-by-step explanation:
So first you let's divide this equation into three parts.
Part one -9x(5x+4)
Step one: you have to distribute the -9x to the numbers in the parentheses. That would leave us with a -9x*5x = -45[tex]x^{2}[/tex] and -9x*4 = -36xStep two: Put the answers together. That would leave us with -45[tex]x^{2}[/tex]-36x.Part two 10(x+3)
Step one: you have to distribute the 10 to the numbers in the parentheses. That would leave us with a 10*x = 10x and 10*3 = 30Step two: Put the answers together. That would leave us with 10x+30Part three solve
Step one: combine and put together what you have solved for. That would leave us with a -45[tex]x^{2}[/tex]-36x+ 10x+30 Step two: combine like terms. The like terms here are -36x and 10x. When you combine them you would get -26x.Step three: Write the equation in standard form. Therefore the answer is -45[tex]x^{2}[/tex]-26x+30.Let me know if anything is confusing!

The scores for all the sixth graders at Roberts School on a statewide test are normally distributed with the mean of 76 and a standard deviation of 10.
What percent of the scores were below 66?
What is the probability that a student earned a score between 66 and 86?
Answer:
a) 15.866%
b) 0.68268
Step-by-step explanation:
The scores for all the sixth graders at Roberts School on a statewide test are normally distributed with the mean of 76 and a standard deviation of 10.
We solve the above question using z score formula
= z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 76
σ is the population standard deviation = 10
a) What percent of the scores were below 66?
x < 66
Hence,
z = 66 - 76/10
z = -1
Probability value from Z-Table:
P(x<66) = 0.15866
Converting to Percentage =
0.15866 × 100
= 15.866%
b) What is the probability that a student earned a score between 66 and 86?
For x = 66
Hence,
z = 66 - 76/10
z = -1
Probability value from Z-Table:
P(x≤ 66) = 0.15866
x = 66 = 0.15866
For x = 86
Hence,
z = 86 - 76/10
z = 1
Probability value from Z-Table:
P(x≤ 86) = 0.15866
x = 66 = 0.15866
Probability value from Z-Table:
P(x = 86) = 0.84134
The probability that a student earned a score between 66 and 86 is calculated as:
P(x = 86) - P(x = 76)
= 0.84134 - 0.15866
= 0.68268
