Find the area of the trapezoid, I will give brainlist. If you can please explain how you got the answer
Answer:
36 sq inches
Step-by-step explanation:
bases are the two parallel sides -- 8" and 4"
height is perpendicular to the base -- 6"
formula for area of a trapezoid: A = 1/2h·(sum of bases)
A = 1/2(6)(8 + 4)
A = 3(12)
A = 36 sq inches

Which number is an integer?
Answer:
Step-by-step explanation:
Can you please specify on that question
Answer:
Integers are numbers that include the negatives, zero and positives.
Step-by-step explanation:
If you ever get confused there's a big circle chart to help you remember look for it online!! What I use to remember is visualizing a number line!
First is the real numbers, so the numbers we were taught since we were little like 1, 2 ,3, 4, 5, 6 and so on. So that's the first part of the number line.
Next is the whole numbers so you just add a zero to that number line. Whole numbers is just all of the real numbers + the number zero.
Then it's the integers so you add the left side of that number line. Integers are real numbers, whole numbers, and negatives. So basically on the number line it's the negatives , zero, and the positives.
Last it's the radicals so all parts of a number like fractions and decimals. So you can add .5 in between the numbers of that numberline.
I hope this strategy helped and if it didn't here's that circle chart!!
I really hope this did help tho!!

A woman bought a bag of rice for $5700 and in 3 weeks later,she could only buy 3/4 of a bag for $5700. Find the percentage increase.
Answer: 25%
Step-by-step explanation:
3/4x=5700
x = 7600
7600 - 5700 = 1900
19/76 = 25/100 which is 25%
Hope this helps!
what would I put to show my work?
Answer:
x = 23
Step-by-step explanation:
These are supplementary angles so the sum of those angles add up to 180:
3x + 16 + 5x - 20 = 180
8x - 4 = 180
8x = 180 + 4
8x = 184
x = 184/8
x = 23

Micheal home is 12 feet below and his mother's home is 12 above sea level
Micheal says their homes are elevations because they are in opposite directions Is he correct? Explain.
Answer:
Yes, Michael is correct. The elevation is measured in terms of sea level. Because Michael's home is 12 feet below sea level and his mother's home being 12 feet above sea level, their homes are at equally opposite directions.
What whole number best approximates the value of x?
The answer is 87
For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4
the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up

The length of a rectangle is 3yd longer than its width. If the perimeter of the rectangle is 26 yd ,find its area
Answer:
A=40
Step-by-step explanation:
There are two sides of a rectangle that are the length.
So at 3 twice.
3+3=6
Subtract it from 26.
26-6=20
Divide by 4
20/4=5
Width= 5
Add 3 to 5
3+5=8
L=8
Check:
5+8+5+8=26
10+16=26
26=26
Area= L*W
8x5=40
A=40
Hope I'm correct!

Find the volume of the cube shown at the right. h=6in
Answer:
216 in³
Step-by-step explanation:
The volume of a rectangular prism is length x width x height
A cube is a special rectangular prism in which all the edges are the same length (like a square)
To find the volume of a cube given the height 6 just solve 6·6·6=216
Don't forget your units and since you cubed 6 inches, they are now in³ or inches cubed

Step-by-step explanation:
Happy Paws charges $20.00 plus $3.50 per hour to keep a dog during the day. Woof Watchers charges $10.00 plus $4.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
Answer:
8 hours
Step-by-step explanation:
Create an equation that sets the costs equal to each other, where h is the number of hours
3.5h + 20 = 4.75h + 10
Solve for h
3.5h + 20 = 4.75h + 10
20 = 1.25h + 10
10 = 1.25h
8 = h
So, it will take 8 hours for the costs to be equal
70% of s is 455, what is s?
Answer:
650
Step-by-step explanation:
[tex]7/10s = 455\\7s = 4550\\s = 650[/tex]
Answer:
650

Find the 75th term: 88, 81, 74, 67, 60
Answer:
a₇₅ = - 430
Step-by-step explanation:
There is a common difference between consecutive terms, that is
d = 81 - 88 = 74 - 81 = 67 - 74 = 60 - 67 = - 7
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 88 and d = - 7 , then
a₇₅ = 88 + ( 74 × - 7) = 88 - 518 = - 430
The 75th term of the arithmetic progression is -430
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is
Tn = a + (n - 1) d, where Tₙ = nth term and a = first term.
Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP : Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the Arithmetic progression be = 88 , 81 , 74 , 67 , 60 ...
The first term of the AP is a ₁= 88
Now , the common difference of the AP d = second term - first term
= 81 - 88
= -7
Now , the nth term of the arithmetic progression is given by ,
Tn = a + (n - 1) d
Substituting the values in the equation , we get
T₇₅ = 88 + ( 75 - 1 ) ( -7 )
= 88 + 74 ( -7 )
= 88 - 518
= -430
Therefore , the value of T₇₅ is -430
Hence , The 75th term of the arithmetic progression is -430
