Answer:
-19
Step-by-step explanation:
-7x + (-12)
= 7x - 12 [ Note: +(-12) = - 12] .
= -19.
17. Perpendicular
18. Parallel
19. Y= -5x-3
The area of a rectangle is the multiplication of its width times its length, that is:
area = width*length
We have to write as an equation the information about the relationship between the width and the length, they say the width is 1/4 of the lenght, this is:
width = lenght/4
now we substitute the data we have:
area = width*length
144 = (length/4)*length
length^2 = 4*144 = 576
the length is raised to the second power because we had to multiply length*length, so to solve the last equation we had to take the square root to both sides:
length = √576
<span>length = 24
</span>so the length of the banner is 24 feet, and we know that:
<span>width = lenght/4
</span><span>width = 24/4
</span>width = 6
so the width is 6 feet
Answer:
Step-by-step explanation:
5n = 5 * 4 = 20
m = 2
5n + m = 20 + 2 = 22
Question 1:
The volume of a sphere is given by:
V = (4/3) * (pi) * (r ^ 3)
Where,
r: sphere radio
Substituting values we have:
V = (4/3) * (3.14) * ((10/2) ^ 3)
V = 523.3333333
Rounding the nearest whole number we have:
V = 524 m ^ 3
Answer:
option 1
V = 524 m ^ 3
Question 2:
The area of a sphere is given by:
V = (4) * (pi) * (r ^ 2)
Where,
r: sphere radio
Substituting values we have:
V = (4) * (3.14) * ((15/2) ^ 2)
V = 706.5
Rounding the nearest whole number we have:
V = 706.5 yd ^ 2
Answer:
V = 706.5 yd ^ 2
option 2
