find the area of the figure
A) 114cm
B)350cm
C)418cm
D)447cm
Answer:
409 is what I got.
Step-by-step explanation:
361 cm, as the square's area
and 48 as the area for the triangle.
Are you sure those are the answer choices because I'm getting 409.
Answer:
HEY!
THE TOTAL AREA OFTHE FIGURE = AREA OF SQUARE + AREA OF TRIANGLE
= [tex]a^{2}[/tex] +( [tex]\frac{1}{2}[/tex] x b x h)
where , [tex]a^{2}[/tex] = 19 x 19 = [tex]361 cm ^{2}[/tex]
and ( [tex]\frac{1}{2}[/tex] x b x h) = ( [tex]\frac{1}{2}[/tex] x 6 x 19) = ( [tex]\frac{1}{2}[/tex] x 114) = ( [tex]\frac{114}{2}[/tex] ) = [tex]57 cm^{2}[/tex] =
∴ [tex]361 cm ^{2}[/tex] + [tex]57cm^{2}[/tex] = [tex]418cm^{2}[/tex]
∴ 418 cm²

HELP ME ON ALEKS HW The figure below has a point marked with a large dot. First, translate the figure 7 units down. Then, give the coordinates of the marked point in the original figure and the final figure.
is there suppost to be a picture because i dont see it..
Answer:
Original: (1,1) Final: (1,-6)
Step-by-step explanation:
When you translate a shape on a coordinate plane, you are moving it vertically or horizontally, without changing it in any way (you are NOT rotating, reflecting, or dilating).
If we look at the large dot on the image, we see it is at (1,1). To move it down 7 units, count down seven units from the dot, and you will get (1,-6).

The histogram below shows information about the hours students spent exercising in a week:
A histogram is titled Weekly Exercise, the horizontal axis is labeled Hours of Exercise, and the vertical axis is labeled Students. The range on the horizontal axis is 0 to 4, 5 to 9, and 10 to 14. The values on the vertical axis are from 0 to 10 at intervals of 1. The first bin goes to 4, the second bin to 9, the third bin to 5.
Which information is provided in the histogram?
A:The number of students who exercised 4 hours or more
B: The number of students who exercised 9 hours or fewer
C:The mean hours of exercise
D:The median hours of exercise
Answer: A
Step-by-step explanation: with my calculation, and the information you have give i have to say it is A.
Answer:
C and D are somewhat correct. We may be able to estimate the mean and median hours from the histogram.
A seems to the closest answer, but not exactly correct.
Step-by-step explanation:
It seems that none of the descriptions is exactly right. The first bin is 0 to 4 hours, so the "4 hours or more is not accurate. The third bin is 10 to 14 hours, so B is wrong.

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.
Answer:
U first need to find out the total number of people
22+28
50
and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator
22/50
And now to make it into % we need to ALWAYS multiply the fraction by 100
22/50 x 100
44%
Hope it helps
Answer:
44 %
Step-by-step explanation:
okay so 100% is equal to the whole team or 50 swimmers
100% = 50 swimmers
to find out how much one swimmer is would be to divide the 100% by the total of swimmers.
100% / 50 swimmers
2% = 1 swimmer
so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.
2 x 22 = 44

Answer:
2 left, 5 down
Step-by-step explanation:
The translation (right, up) is the difference of the coordinates:
J'(-3, -1) -J(-1, 4) = (-3+1, -1-4) = (-2, -5)
The image has been translated left 2 and down 5.

Additional comment
A negative distance "right" is a positive distance "left". Likewise, a negative distance "up" is a positive distance down.
If you prefer a visual representation, a graph can help.
