Find the area of the polygon. A = __ft squared
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)
57/2= 28.5
So, the anwser is 28.5^2

Answer:
She probably was supposed to multiply, instead of add.
Step-by-step explanation:
First multiply 24 and 32, which is 768.
Second multiply 768 and 12, which is 9216

Answer:
y = -90x + 2000
Step-by-step explanation:
Hello There!
So we need to write an equation of the line in slope-intercept form
y = mx + b
where m = slope and b = y intercept
They give us everything in the caption
They say that a hot air balloon descends from 2000 feet at a constant rate of 90 feet per minute
Descends from 2000 feet indicates that the hot air balloon starts at 2000 feet
Thus this is the y intercept
Descends indicates that the slope is going to be negative because descend means to go down
The hot air balloon descends at a constant rate of 90 feet per minute
Thus meaning that the slope is -90
Now that we have everything we add it all together and get that the equation is
y = -90x + 2000
hope this helps :)
Answer:
y = -90x + 2000
Step-by-step explanation:
in y = mx+b, m is the slope and b is the y intercept
Therefore the y intercept is 2000
Now we have y = mx + 2000
Because the balloon descends at 90 ft/min, the m value is -90
So the answer is y = -90x + 2000

The price to travel in a taxi in a certain large city costs $2.50 for the initial fare and $0.50 per mile. The cost to ride in a town car in the same city is $3 per mile. Which of the following is true?
The slope of the line for the graph representing the taxi cost is steeper than the slope of the line of the graph representing the town car.
The slope of the line for the graph representing the town car cost is steeper than the slope of the line of the graph representing the taxi.
The y-intercept on the graph of the town car is greater than the y-intercept of the graph of the taxi.
The y-intercept is zero for both graphs.

Step-by-step explanation:
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?
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

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)}
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
take care :)

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)
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.
