Answer:
Step-by-step explanation:
Let the number be x
5 times a number = 5x
24 - 5x = 15
-5x = 15-24
-5x = -9
x= -9/-5
x = 9/5

or x = 1.8
A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
The answers have square roots among the choices so we probably shouldn't use that calculator button.
We can't just apply the area of the trapezoid formula

where b is the bottom base, t the parallel top, and h the height, because we don't know the top t.
It will be 10 less the leg of that right triangle, which we calculate as

Now we can apply the trapezoid formula. We have


Choice b
Answer: no
Step-by-step explanation:
because you can do what is known as the vertical line test to determine if it is a function you do that by plotting it and if it goes in a vertical line then it is a function
You can set up an equation for this. if x is the amount of weeks, and m is total money, then it'd be
500+75x=m
plug numbers in
3 weeks: 500+75*3=$725
10 weeks: 500+75*10=$1250
6 months, each month having 4 weeks, is 24 weeks
500+24*75=$2300
