Answer:

1987.2

Step-by-step explanation:

We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other. Since we know the strength of students increased by 8% to 2160 then the original was 92%.

\frac{92}{100}=\frac{y}{2160}

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

92(2160)=100(y)

198720=100y

y=1987.2

There are 1987.2 as the original strength of students.

Henry used benchmark fraction to compare the lenghts of grasshoppers 5/8 and 7/4. Which grasshopper is longer? Explain.
Goryan [66]
------------------------------------------------------
Change the denominators to be the same
------------------------------------------------------
5/ 8 = 5/8
7/4 = 14/8

Since the denominators are the same, the larger the numerator, the larger the fraction. Therefore 14/8 (7/4) is greater than 5/8. 

14/8 > 5/8
7/4  >  5/8

---------------------------------------------------------------------------------
Answer: The grasshopper that is 7/4 unit long is longer

A horizontal line contains points A, C, B. 2 lines extend from point C. A line extends to point E and another line extends to po
Effectus [21]

Answer:

Option (2).

Step-by-step explanation:

In the figure attached,

A, C and B are the points lying on a straight line.

2 lines EC and DC have been drawn by extending the lines from C to E and D respectively.

Ray CE is the angle bisector of ∠ACD.

That means CE divides ∠ACD in two equal parts.

m∠ACE = m∠DCE

Since m∠ACD = m∠ACE + m∠DCE

                        = 2(m∠ACE)

          m∠ACE = \frac{1}{2}(\angle ACD)

Therefore, option (2) will be the answer.

MissTica
Slope -intercept form : y=mx+b
In other words use this formula y-y1=m(x-x1) where x1and y1 are points from the graph.
To find the slope : m=(y2-y1)/( x2-x1)
Use it for each graph and solve .

A pool company is creating an image for a client that has the look of a 3-D image for a family pool and a similar dog pool. Find
Drupady [299]

Answer:

x = 8

Step-by-step explanation:

==>Given that a family pool with a quadrilateral shape ABCD is similar with the dog pool EFGH, we can find the value of x by using the proportion of their corresponding sides.

Since ABCD ~ EFGH, the proportion of their corresponding sides are equal.

Thus, AB/EF = BC/FG = CD/GH = DA/HE

We have: 3/y = 4/3 = 5/z = x/6

Finding z:

4/3 = 5/z

Cross multiply

4*z = 5*3

4z = 15

z = 15/4

z = 3.75

Let's find x:

5/z = x/6

5/3.75 = x/6

Cross multiply

6*5 = x*3.75

30/3.75 = x

8 = x

x = 8
