Find the area of the polygon. A = __ft squared

Answers

Answer:

28.5^2

Step-by-step explanation:

The formula is, b(base)+c(height)= b+c over 2.  b+c/2.

B=19ft in this problem.

C=38ft

Knowing this, we can further simplify.

19+38/2

Now, we add 19 and 38.

57/2= 28.5

Which is the simplified form of the expression m + 3m + 2 + 2?

Answers

Answer:

If you want to factor it, it will be 4(m+1).If not factored, it will be 4m+4

Step-by-step explanation:

m+3m+2+2

m+3m = 4m

2+2 = 4

4m+4

To factor that, you can take out 4 as a common factor, so it will be (4)(m+1)

Answer:

4m+4

In a regular polygon, the measure of an interior angle is 6.5 times the measure of an exterior angle. How many sides does the polygon have?

Answers

Answer:

15 sides

Step-by-step explanation:

Always the sum of interior angle and exterior angle = 180

Let the exterior angle = x

Interior angle = 6.5 *x = 6.5x

x + 6.5x = 180

7.5x = 180

     x = 180/7.5

     x = 24

Exterior angle = 24°

Sum of exterior angles of any polygon = 360

number of side = Sum of exterior angles ÷ measure of each exterior angle

                         = 360 ÷ 24

                        = 15

The value of the expression at y = 2.5 is 6.25.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

y²

Substitute y = 2.5

= y²

= 2.5²

= 2.5 x 2.5

= 6.25

Thus,

The value is 6.25.

Select the two expressions that are equivalent to 4 + w + 12w.

a
4 + 13w
b
13w2 + 4
c
2(2 + 6w) + w
d
16 + 2w
e
2(2 + 6w2)

Answers

The answer are
A and B

The equivalent values of the expression A = 4 + w + 12w are B = 4 + 13w and C = 2 ( 2 + 6w ) + w

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To find the expressions that are equivalent to 4 + w + 12w, we need to simplify the expression and see which of the given expressions have the same result.

4 + w + 12w = 4 + 13w

So, the equivalent expressions are (a) 4 + 13w and (c) 2(2 + 6w) + w.

Let's check the other options:

(b) 13w² + 4: This is not equivalent, as it involves squaring the w term.

(d) 16 + 2w: This is not equivalent, as it involves adding a constant term.

(e) 2(2 + 6w²): This is not equivalent, as it involves squaring the 6w term.

Hence , the two expressions that are equivalent to 4 + w + 12w are (a) 4 + 13w and (c) 2(2 + 6w) + w.

Which relation is a function?

{(5, 0), (–8, –5), (–8, 5), (–5, –8)}
{(5, 0,) (–8, –5)}
{(5, 0), (0, 5), (–5, –5)}
{(5, 0), (0, –8), (5, –5)}

Answers

Answer:

B. C.

Step-by-step explanation:

when you have a function, you can only have one input for every output, like in A

{(5, 0), (-8, -5), (-8, 5), (-5, -8)}

we have -8 twice in the sets of numbers on the X, so this set is NOT a function

another way to tell is to plot out the points on the graph, then draw a vertical line and run across the sets, if more then one point cross the line at a time, then those points are not a function, this is called a vertical line test

hope this helps, it looks like a multiple choice maybe, bc B. and C. are both functions from what i can see, i hope this was worth the points u spent on this question

help pls im trying to figure out my money i'm saving for a phone ill give brainliest if u can help. i have $16 rn and on march 12th is the 1st day of allowance which is $5 after the end of that week. ill get $5 every week. how long will it take for me to get $303?

Answers

ANSWER : About 15 months. Because 5 x 4 = 20 (4 weeks in a month)

303 Divided by 20 is 15.15. (it's ok I dont need brainliest!)

Answer:

61 (from first pay-week) or about a year and two months

Step-by-step explanation:

then all we have to do is divide that by the amount of money you ern per week (in the case 5) and that will be the amount of allowance days that will take u to your goal

303 / 5 = 60.6

if you want to simplify it, we can round up to 61 weeks wich is about a year and 2 months IF your allowance rate stays the same

however dont feel bad, as time goes on many factors may change this, maybe your allowance may be a little larger, and trust me, a few cents can shave of months sometimes, another thing is that the phone may lose value over time and you may be able to get it before you reach your goal

and keep on the lookout, where theres an expensive item, there is sometimes a WAY cheaper alternative where you may sacrifice a little bit somewhere, but will be worth it in the end

look in the positive direction, it may seem impossible at first, but trust me, this is an achievable goal, good luck mate :D

Over the course of a year, a classroom went from 15 students to 19 students.

Use the drop-down menus to build an equation that could be used to find the percent change, p, in the number of students.

Answers

26.7%

Step-by-step explanation:

The positive change from 15 to 19 is 4.

Find the value of the fraction 4/15 and multiply the result by 100% to obtain the final answer:

4/15 = 0.26667

Multiplied by 100%, 0.26667 becomes 26.7%:  the percentage change in the number of students
