The ratio of girls to boys in the photography club is 7 to 3. Which ratio could represent the members of the photography club?
A. 35 girls : 50 boys
B 14 girls : 9 boys
C 21 girls : 9 boys
D 21 girls : 15 boys
**Use the Explanation and answer**
Answer:
C) 21 girls : 9 boys
Step-by-step explanation:
You just have to compare the ratio you're given to the answers and see if the ratios from the answers match up to the ratio you were given. The reason C is the answer is because if you divide by 3 in the ration, it is the same as the ratio you were given, 7:3
Isabelle is plotted a pentagon on a grid. So far, she has plotted and connected the three points shown on the grid below. To complete the pentagon, she can choose only from the points below.
(2.0) (-2,0), (-2, 4), (2, 4)
How can Isabelle complete her pentagon?
Connect the point already at (0-2) to a new point at (2.0), and then connect
(2.0) to (-2,4)
Connect the point already at (0-2) to a new point at (-2, 0), and then connect (-2, 0) to (-2. 4).
Connect the point already at (0-2) to a new point at (-2, 0), connect (-2, 0) to (24), and then connect (2,4)
to (-2.4)
Connect the point already at (0-2) to a new point at (2.0), connect
(20) to (2.4) and then connect (2.4) to (-2. 4)

Answer:
Isabelle is plotting a pentagon on a grid.
So far, she has plotted and connected the three points shown on the grid below.
On a coordinate plane, lines connect points (negative 2, 4), (negative 3, 2), and (0, negative 2).
To find:
To complete the pentagon, choosing only from the points below. (2, 0), (–2, 0), (–2, 4), (2, 4).
How can Isabelle complete her pentagon?
Solution:
Consider the attached figure, while going through the following steps.
A five sided polygon is called the pentagon.
As Isabelle already plotted and connected the three points, we need to connect the remaining 2 points to obtain a pentagon.
So, from the attached figure, it's clear that, Isabelle needs to connect the points (2, 0) and (2, 4).
By plotting and connecting these above points, Isabelle can complete her pentagon.

Please help me my Math Grade Is a D-
=========================================================
Explanation:
The triangles are similar. We can prove this through the angle angle similarity postulate.
This means we can set up the proportion below to solve for x
(short horizontal)/(long horizontal) = (short vertical)/(long vertical)
12/150 = 8/x
12x = 150*8 .... cross multiply
12x = 1200
x = 1200/12 ... divide both sides by 12
x = 100
------------------
As confirmation:
12/150 = 0.08
8/100 = 0.08
This shows that 12/150 = 8/100
I really need help on this question! Thank you!
Answer:
A
Step-by-step explanation:
We know the following:
[tex]OE=5\\\\FG=4\\\\EF=8\\\\[/tex]
so the segment EF is equal to
[tex]EF=EG+GO+OF\\\\[/tex]
and here we can do a trick :)
[tex]EF=(EG+GO)+GO+(OF+OG)-2GO\\\\[/tex]
you see it's the same
[tex]EF=EO-GO+FG\\\\[/tex]
now we plug the values given
[tex]8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1[/tex]
so it's option A

There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?
Answer:
I think the answer is 171.
Step-by-step explanation:
Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)
I am pretty sure this is right...I hope this helps!
