The ratio depicts that their is 63 boys and 16 girls based on the ratio 7:4.
I hope this helps!

Answer: 198</h3>
The probability of winning is 3/8 since there are 3 winning spaces out of 8 total.
We expect to have (3/8)*528 = 198 winners
Note how if we had 198 winners out of 528 total players, then the empirical probability of winning is 198/528 = 3/8
The solution of the expression is -1 ⇒ 3rd answer
Step-by-step explanation:
Let us revise some important rules on the number line
- If we add number to another number we move to right
- If we subtract a number from another number we move to left
∵ The expression is negative 2 minus 3 minus (negative 4)
∵ negative 2 = (-2)
∵ minus means (-)
(-2) minus 3 means move 3 units from (-2) to left, so you will pass -3, -4, and stop at -5
∴ (-2) - 3 = -5
∵ minus (negative 4) = - (-4)
- Remember (-)(-) = (+)
∴ minus (negative 4) = + 4
That means move 4 units to the right from -5, then you will pass -4, -3, -2, and stop at -1
∴ -5 + 4 = -1
∴ The expression (-2) - 3 - (-4) = -1
The solution of the expression is -1

Answer:
5770 feet
Step-by-step explanation:
The height of the wall under the Waters proposal is 20 feet and the height of the wall under the Barrett proposal is 34 feet and its perimeter is 9809 feet. Since there is an increase in the dimensions of the wall, we find this percentage increase.
So, the percentage increase in the height of the wall is thus (New height - Old height)/Old height × 100%
New height = 34 feet and Old height = 20 feet
So, Percentage increase = (New height - Old height)/Old height × 100% = (34 ft - 20 ft)/20 ft × 100 % = 14/20 × 100% = 7/10 × 100% = 70 % increase.
Since all the dimensions increase by the same amount, the perimeter in the Waters proposal increases by 70% to the perimeter in the Barrett proposal.
Let P = perimeter in the Waters proposal and P' = perimeter in the Barrett proposal.
So, the percentage increase in perimeter is
(P' - P)/P × 100 % = 70 %
We now find P
(P' - P)/P = 70%/100%
(P' - P)/P = 0.7
P' - P = 0.7P
P' = 0.7P + P
P' = 1.7P
P = P'/1.7
So, substituting the value for P' = 9809 feet
P = P'/1.7
= 9809 ft/1.7
= 5770 feet
So, the perimeter of the wall under the Waters Proposal is 5770 feet.
Hi! I’m thinking back to rotation translation and reflection and I would say this is a translation
