hurry please! how can you simplify and evaluate expressions with exponents?

Answers

Answer:

You can use the order of operations to evaluate the expressions containing exponents. First, evaluate anything in Parentheses or grouping symbols. Next, look for Exponents, followed by Multiplication and Division (reading from left to right), and lastly, Addition and Subtraction (again, reading from left to right).

Ava makes bead bracelets. She has a total of 6,048 beads. each necklace has 24 beads. Her friend Maria says that the greatest number of bracelets she can make with the beads is 162. Explain why Maria's answer is incorrect and how she can find the right answer.

Answers

Each necklace needs 24 beads
Ava has 6,048 beads
To find out how many bracelets she can make we need to see how many time 24 can fit into 6,048 with no remainders
6048 divided by 24 is 252

Maria’s incorrect because to make 162 bracelets you would need 3888 beads because: 162 x 24 = 3888
This is not the greatest amount of bracelets because the are excess beads

Answers

the Answer:

y=1/3x+5

Step-by-step explanation:

By looking at the 2 points, we can see that (x1, y1) is (0, 5) which is the y-intercept, hence the +5 in the answer. The y-intercept is the y-value whenever x is 0. Next, we know that (x2, y2) is (6, 7) Remember that the (x2, y2) is always the right-most coordinate of the 2 points chosen. We now can apply the formula for finding a slope which is y2-y1/x2-x1. By substituting, we get 7-5/6-0 Which gives us 2/6 but notice the question wants coefficients in simplest form. 2 and 6 can be halved, which gives us 1/3, hence the 1/3x in the equation. The Slope-Intercept form will always be y=mx+b where m is the slope and b is the y-intercept. If m is 0 then the line will be horizontal. Hope this helps!

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $2,260 was collected on the sale of 1,060 tickets. How many of each type of ticket were sold?

Answers

A = number of adult tickets
S = number of student tickets
1033 = total tickets sold
A + S = 1033

5(A) = money collected for adult tickets
S(1) = money collected for student tickets
2265 = total money collected
5(A) + S(1) = 2265

two equations and two unknowns:
5A + S = 2265
A + S = 1033

subtract 2nd equation from 1st and solve for A:
4(A) = 1232
Divide 1232 by 4 and
A = 308

Plug in value for A in 1st equation and solve for S:
A + S = 1033
308 + S = 1033
S = 725

725 student tickets and 308 adult tickets were sold

Eight students got a B on the final test. If the ratio of the number of studenst who got an A to the number of student who got a B is y : X, how many students got an A? What if x is 2 and y is 3?

Answers

Answer:

1) x = 2 and y = 3: 12 students got an A.

2) x = 4 and y = 3 6 students got an A. (from the comments)

Step-by-step explanation:

Hopefully I read this right, but the ratio you're trying to find is A : B = y : x

1) Plug in x = 2 and y = 3 to get 3 : 2. Because we know 8 students got a B we're going to multiply by 4 on each side to get 12 : 8 (12 A students and 8 B students).

2) You asked this in the comments so I answered it as well. Do the same thing as 1):

Plug in x = 4 and y = 3 to get 3 : 4.

We know there's 8 B students so multiply by 2 to get 6 : 9. 6 A students and 9 B students.

If x is 2 and y is 3, the number of students that goat an A is 12.

What are ratios?

Ratio expresses the relationship between two or more numbers. It shows the frequency that one value is contained within other value(s).

How many students got an A?

In order to determine this, divide 8 by 2: 8/2 = 4

Multiply 4 by 3 = 12
