Answer:
16 robots make noise
Step-by-step explanation:
The first one is done and the options for number four are:
w(2w+12)=160
2w^2+12w-260=0
2w^2+12w=260
w^2+6w-130=0
Answer:
Step-by-step explanation:
Part A
w² + 6w + c = 130 + c
w² + 2(3w) + c = 130 + c
To make left side of the equation a perfect square we will replace c by (3)².
w² + 2(3w) + 3² = 130 + c
[By formula → a² + 2ab + b² = (a + b)²]
w² + 2(3w) + 9 = 130 + 9
Therefore, c = 9 will be the answer.
Part B
From part A,
(w + 3)² = 139
Option (2) and Option (6) are the correct options.
Part C
w + 3 = √139
w = 11.79 - 3
w = 8.79
w ≈ 8.8 inches
What is the solution to the system of equations graphed below?
There are 120 athletes
register at the club.
If 48 athletes are girls, determine:
1. the number of girls in the club as a percentage of the total number of registered
athletes
2. the ratio of girls : boys registered at the club.
Answer:
0.48%
when we subtract 48 from120 we get 72 so 72 is the number of boys are there so we divise them and we get 2 ratio 3

Answer:
False.
Step-by-step explanation:
A cone is not a solid made from a disc, a point not in the same plane as the discs and all points between them.
Mathematically, the volume of a cone is given by the formula;
[tex] V = \frac{1}{3} \pi r^{2}h[/tex]
Where;
V is the volume of the cone.
r is the radius of the base of the cone.
h is the height of the cone.

When melissa is born her parents invested 2,000 in a fund that paid an annual interest of 6%. How old will melissa be when the investment is worth at least $5,000?
Answer:
25 years
Step-by-step explanation:
Given data
Principal P= $2000
Interest rate r= 6%
FInal amount A=$5,000
The simple interest formula is given as
A=P(1+rt)
substitute and solve for t
5000=2000(1+0.06*t)
5000=2000+120t
5000-2000=120t
3000=120t
t= 3000/120
t= 25 years
Hence, for a simple interest investment, she will be 25 years

Z-31=16??? I just got into the Z section in algebra and my teacher gave us a paper with no explanation plz help ty!
Answer:z=47
Step-by-step explanation:
You're doing this because if you have z-31=16 you have to + 31 to 16 which would give you 47 then that would be a one step equation
z-31=16
you would make a line between the equal sign so it is organized then plus 31 to sixteen then that would get you to 47
write the equation of the line in fully simplified slope-intercept form.
