Answer: Good thing you provided the image!
Working down the columns:
C base= 2
D base = 4
C height =3
D height = 2
C area = bh = 8
D area = bh = 8
Step-by-step explanation:
Try thinking about drawing a rectangle around the entire image of C and D, connecting each of the corners (sort of like what is being done for B) and then you can perceive the b and h.
The trick to D is to turn your head 90 degrees (or sideways) so you can see those 4 boxes as the base.
For C the base is the 2 boxes, and going up until you meet the other parallel side you can count 4 boxes.
I usually default to using the side which I can easily count boxes as the base and go from there.
Answer:
560 students
Step-by-step explanation:
We are given that the total number of students is
700
The survey results is 80% likes the new lunch menu
We are expected to establish what amount of students is 80%
=80/100*700
=0.8*700
=560
Hence 80% of 700 is 560
Answer:
example 4:2
Step-by-step explanation:
A proportion shows how many parts of one side equals the other. For every four times i kick a soccer ball, I make it in twice. For every 8 times, I make it in 4.
Y-2=-3/5x -6/5
(5)(y-2)=(-3/5x-6/5)(5)
5y-10=-3x-6
5y+2x=4
Answer:
9 magazines
Step-by-step explanation:
To solve this problem you will want to work backwards. Start with the junk mail. There is 18 junk mail and if there are 1/3 as many bills as junk mail then you will need to multiply 18 * 1/3. This equals 6 bills. If there is twice as many bills as letters then you will need to divide bills(6) by 2 which equals 3. If there are 6 more magazines than letters then you need to add 6 to the letters (3). 3 + 6 = 9
