Please help me there due tonight!!! All help is appreciated.
Answer:
1. 160cm²
2. 176.25cm²
3. 33.75ft²
Step-by-step explanation:
Area triangle = (1/2)(base)(height)
1)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(8)(9))+2(0.5(8)(11))
=72+88=160cm²
2)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(7.5)(7.5))+2(0.5(7.5)(16))
= 56.25 + 120 = 176.25cm²
3)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(4.5)(2.5))+2(0.5(4.5)(5))
= 11.25+22.5 = 33.75ft²

proof on pic......................
Both table A and Table B below represent linear relationships.
Based on the information in the tables, which statement is true?
Group of answer choices
Both Table A and Table B represent proportional relationships.
Table A represents a proportional relationship but Table B does not.
Neither Table A nor Table B represent a proportional relationship.
Table B represents a proportional relationship but Table A does not.
Answer:
Both represent a proportional relationship
Step-by-step explanation:
This is because when the independent variable in each table increases, the dependent variable increases as well, making the relationship proportional.
Write 2 1/4
as an improper fraction.
Answer:
9/4
Step-by-step explanation:
First multiply denominator by the whole
That is: 4 x 2 = 8
Secondly, whatever answer you got add it to the numerator
That is: 8 + 1 = 9
Lastly, whatever answer you got, take that as the numerator and the denominator remains the same
That is: 9/4
Finally, this is your improper fraction of the number provided!
Hope it helps!!!
If the surface area of the box of cereal is 272 inches squared, find the length of the box.
Answer:
x= 8 inches
Step-by-step explanation:
you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-
dimensions of the box:
12 in x 2 in x ?
=272 square inches
and we know that there are 6 faces
area= 2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)
area = 272 sq. in. = 48 + 4x + 24x
272 = 48 + 28x
272 - 48 = 28x
224 = 28x
x = 8 inches
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!

Find the area of the trapezoid. If the answer is not an integer, leave it in simplest radical form. The figure is not to scale
Answer:
150 ft²
Step-by-step explanation:
Area of trapezoid = ½(a + b)h
Where,
a = 24 ft
b = 24 + 12 = 36 ft
h = √(13² - 12²) = √25 = 5 ft (pythagorean theorem was applied here)
Plug in the values
Area of trapezoid = ½(24 + 36)*5
= ½(60)*5
Area of trapezoid = 150 ft²

Amanda can jog 18 miles in 5 hours.
Answer:
the probelm does not make sense
Step-by-step explanation:
you can try dividing
Answer:
14.4 miles
Step-by-step explanation:
Amanda can jog 18 miles in 5 hours.
At the same rate how many miles can Amanda jog in 4 hours=??
solution:
Distance covered by Amanda in 5 hours = 18 miles
Distance covered in 1 hour = 18/5 miles
Distance covered in 1 hour is =3.6
Distance covered in 4 hours = 4*3.6=14.4
Hence Amanda can jog 14.4 miles in 4 hours

A painter sets a ladder
against a wall 9 ft above
the ground. If the ladder is
3 feet from the base of the
wall, how long is the ladder?
Round your answer
to the nearest tenth.
Answer: About 10 ft.
Use Pythagorean's Theorem!
c=[tex]\sqrt{9^2+3^2}[/tex]
9 * 9 = 81
3 * 3 = 9
81 + 9 = 90
[tex]\sqrt{90\\}[/tex] = 3[tex]\sqrt{10}[/tex] ≈ 10 ft.

Four friends share 3 sheets of construction paper equally. What fraction
of a sheet of paper does each friend get?
Answer:
0.75 or 3/4 sheet of paper
Answer:
3/4 of each sheet
Step-by-step explanation:
You have to divide the number of sheets of paper by the number of people sharing them, which gives you 3/4. This makes sense because if there are more people than paper, each person will get less than a full sheet.

What is the median of the numbers 312, 336, 488, 384, 368, 336, 416, 624
Answer:
376
Step-by-step explanation:
312,336,336,368,384,416,488,624
the middle numbers are 368 and 384
the median is the middle of the middle numbers
to find this number we add up 368 and 384 and divide the answer by 2
368+384=752
752/2=376
Answer:
376
Step-by-step explanation:
1. To find the median you have to first arrange the numbers in numerical order.
2. Count how many numbers you have.
3. Divide by 2. Go to the number in that position and average it with the number in the next highest position to get the median.
So considering you have 8 numbers if you divide 8 ÷ 2 = 4
the 4th number arranged is 368. Now to average 368 and 384. 368+384=752
752 ÷ 2 = 376
