<u>Answer:</u>
16 men
20 women
<u>Step-by-step explanation:</u>
We are given that the ratio of the number of men to the number of women on a bus was 2:3 at a bus stop.
So assuming x to be the number of persons (male or female), we can write it as:
When 4 women got off the bus, the ratio changed to 4:5.
Solving it to find x:
So, number of men on the bus = = 16
and number of women on the bus at the end = = 20
Answer:
y = -1
Step-by-step explanation:
Any ordinate pair (x, y) represents the input output values of a function to be graphed.
For any input value of x, there will be an output value (y).
If input value for the graph attached is x = 0,
Output value will be represented by the y-value along y-axis as, y = -1
Therefore, y = -1 will be the answer.

Question 1
We first have to convert everything to yards since the concrete is charged by the cubic yards
15 feet = 5 yards
15 feet = 5 yards
3 inches = 0.08333
Multiply these to find the volume
5 * 5 * 0.08333 = 2.08325
Multiply this by the cost
2.08325 * 46 = 95.83
The answer is C) $95.83
------------------------------------------------------------------------------------------------------
Question 2
You have to find the volume of the first pyramid
The equation we use is
V is volume
l is length
w is width
h is height
Put in the values we know
Multiply
Divide
V = 2389.3333
Now we use this to find the side length of the second pyramid
Multiply both sides by 3
<span>7167.999 = lw * 112
</span>
Divide both sides by 112
63.9999 = lw
Since it is a square pyramid we know that sides are equal
63.999 = l^2
Take the square root of both sides
8 = l
The answer is B) 8in
Hope this helps!
