Answer:
24
Step-by-step explanation:
The first thing I did was divide 42 by 7 to get the equivilant for 1.
42 ^ 7 = 6
So,
1 = 6
This means that all you have to do to get the amount of men is to multiply 4 by 6.
4 * 6 = 24
So, there are 24 men and 42 females.
Hope this helps!

Find the measure of the given angles. Show work!!
Given:
The figure of a right angle triangle.
To find:
The value of x and measures of all angles of the triangle.
Solution:
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
Using angle sum property, we get
[tex](x+60)^\circ+(x+50)^\circ+90^\circ=180^\circ[/tex]
[tex](2x+200)^\circ=180^\circ[/tex]
[tex](2x)^\circ=180^\circ-200^\circ[/tex]
[tex](2x)^\circ=-20^\circ[/tex]
It can be written as
[tex](2x)=-20[/tex]
Divide both sides by 2.
[tex]x=-10[/tex]
The value of x is -10.
Now,
[tex]m\angle A=x+50[/tex]
[tex]m\angle A=-10+50[/tex]
[tex]m\angle A=40[/tex]
And,
[tex]m\angle B=x+60[/tex]
[tex]m\angle B=-10+60[/tex]
[tex]m\angle B=50[/tex]
Therefore, the value of x is -10, measure of angle A is 40 degrees and measure of angle B is 50 degrees.
In rectangle ABCD, AD=200, and diagonal AC=90, what is the perimeter of ABCD
Answer:Length = 200
Breadth=90
perimeter of rectangle
[tex] = 2(l + b) \\ = 2(200 \times 90) \\ = 2 \times 18000 \\ = 63000[/tex]

Tommy is looking at a tall building.
The building is casting a shadow 48
feet long. Tommy is 6 feet tall and
his shadow is 4 feet. How tall is the
building?
Answer:
tommy is 6ft and makes a 4ft tall shadow
which means that the building would make a shorter shadow then its height.
48/4=12
12*6=72
72ft

Let me know if you can see the image, also answer to.
Answer:
Part A) About 3 it represents the amount of matches won with 0 months of practic3
Part B) points used = (2,8) (5,12)
equation in slope intercept form: y=[tex]\frac{4}{3}x +3[/tex]
games won after 13 months = about 20
Step-by-step explanation:
Part B work:
points used = (2,8) (5,12)
[tex]\frac{ y_{1} -y_{2} }{x_{1}- x_{2} }[/tex] = slope equation
[tex]\frac{12-8}{5-2}[/tex]= slope equation filled in
[tex]\frac{4}{3}[/tex]=slope
So the equation in slope intercept form:
y=mx+b
mx = slope
b = y intercept
So the equation is:
y=[tex]\frac{4}{3}x +3[/tex]
Games won after 13 months:
months = x
y=[tex]\frac{4}{3}[/tex](13) + 3
4/3 x 13 = 17.3
y=17.3+3=20.3
About 20 games

How do you fnd the total amount of an interest paid? The question is "Find the total amount of interest paid one a principal of $2600 at a rate of 12% calculated per annum over 3 years." and I'm not sure how to figure it out
Answer:
936
Step-by-step explanation:
Because 12%of 2600= 312
or 0.12×2600=312 for the first year
so multiply by 3 to get interest for 3 years
312 × 3 =936

Look at the two equations:
-3x + 6 = 21
-3x + 6 < 21
Which statement best describes the process used to solve the equations?
In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality.
The process is exactly the same for solving the equation and solving the inequality.
The process for solving the equation is entirely different from solving the inequality.
