Answer:
3.78
Step-by-step explanation:
Percentage solution with steps:
Step 1: We make the assumption that 9 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=9$.
Step 4: In the same vein, $x\%=42$.
Step 5: This gives us a pair of simple equations:
$100\%=9(1)$.
$x\%=42(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{9}{42}$
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{42}{9}$
$\Rightarrow x=466.67\%$
Therefore, $42$ is $466.67\%$ of $9$.
Answer: S<\-2
Hope i was some help.
Step-by-step explanation: sorry I can’t put the right sign my keybored won’t let me but you know what it stands for.
3s+6s</-5(s+2)
start off with -5(s+2) you multiply -5 with s and it is -5s then you do the same for +2 take -5 and multiply by +2 pos times a neg is always a neg so it’s -10.
3s+6<\-5s-10
So you have to get rid of the -5s so your going to do the inverse which is add 5 to -5 and it will get rid of -5s but then you have to add 5 to 3s and that will be 8s.
8s+6</-10
Now your going to get rid of the +6 and to do that you do the inverse you subtract 6 and it will get rid of it now you have to do the same for -10 so you will subtract 6 to -10 and that will equal -16.
Now you have to divide!
8s/8 </ -16/8
And it should equal s <\-2
Answer:
Step-by-step explanation:
I will use substitution
We will substitute the answer for y into the bottom equation
x+(4x+3)=-2
5x+3=-2
5x=-5
x=-1
Now solve for y
(-1)+y=-2
y=-1
Write as an ordered pair
(-1.-1)
• measure of the side: s = 3 in
You can find the height h by this formula:
s · √3
h = ————
2
3 · √3
h = ————
2
3√3
h = ———— in (exact value)
2
Using √3 ≈ 1.73,
3 · 1.73
h ≈ —————
2
5.19
h ≈ ————
2
h ≈ 2.60 in (approximate value)
I hope this helps. =)
Answer:
a) 90 cubic foot
b) 90 cubic foot = 667.62 gallons
c) $3.3381
Step-by-step explanation:
a)
volume of rectangular hot tub
= 6*5*3
= 90 cubic foot
b)
1 cubic foot = 7.418 gallons
90 * 1 cubic foot = 90 * 7.418 gallons
90 cubic foot = 667.62 gallons
c)
$5 = 1000 gallons
($5 / 1000) = (1000 / 1000) gallons
.005 * 667.62 = 1 * 667.62 gallons
$3.3381 = 667.62 gallons
