The equation h=60-4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain
Answers
Answer:
40m
Step-by-step explanation:
Complete question
The equations h = 60 - 4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain. How high is the water after 5 minutes.
To get the height of the water after 5minutes, we will find h at when m = 5
h = 60 -4 (5)
h = 60 - 20
h = 40m
Hence the water is 40m high after 5minutes
Solve for x.
-3(4x-16)=-12
I need an answer and explanation so I can try to do some myself thanks!:)
Answers
Answer:
B. -5
Step-by-step explanation:
this is quite simple, so what you are going to want to do is multiply -3 by 4, and -16, so distribute that and you'll end up with
-12x+48= -12
then you want to subtract 48 from both side to leave the x on one side alone
that will be -12x= -60
after that you have to divide both sides by -12 to find your x
so then you will see that your x is = -5! hope this helps!!
A container is in the shape of a cuboid the cuboid is 2/3 full of water a cup holds 275 ml of water what is the greatest number of cups
Answers

Answers
Answer:
3.78 yd
Step-by-step explanation:
Rectangle area = length x width
a = (w+10)*w = w² + 10w = 52
w² + 10w - 52 = 0
w = (-10 ± √10²-4*1*(-52)) / 2 = (-10 ± √308)/2 = (-10 ± 17.55)/2
width must be positive: w = (-10 + 17.55)/ 2 = 7.55/2 = 3.78

Determine the probability of hitting the target
This calculated using:
[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]
[tex]P(Hits) = \frac{84}{120}[/tex]
[tex]P(Hits) = 0.70[/tex]
Hence, the probability of hitting the target is 0.70

Answers
Answer:
1. a. 544%
b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44
5.44*100=544
b. 1.96/2.32=0.84
0.84*100=84
2. let x = # of 7th graders
let y = # of 8th graders
y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175
3. A=P(1+r)^t
A=700(1+0.055)^4
A=867.18
