Answer: All you need is to measure your fish tank's length (from side to side), height (from top to bottom of the tank), and depth (from front to back) and you can figure out how much water your aquarium holds! Tank Width: Numbers only, please. The width of an aquarium is the distance across the front.

At summer camp, the cook asks 6 campers to help with slicing watermelons. Each camper slices 4 ½ watermelons. How many melons do the campers slice?
Answer:
27 melons
Step-by-step explanation:
Number of melons sliced = Number of melons sliced by each camper * number of campers
= 4 1/2 * 6
[tex]= \frac{9}{2}*6\\\\=9*3\\\\= 27[/tex]
Answer:
Solution :-No. of campers = 6
Melon slice by 1 camper = 4½
Total melons sliced = 4 ½ × 6
Total melons sliced = 9/2 × 6
Total melons sliced = 9 × 3
Melons sliced = 27★

A plane is going to fly 400 miles at a planned speed of 570 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time T, in hours, of the flight is a function of the speed of the headwind w, in mph, and can be modeled by
T(w) = 400/570 - W
a) What does T(150) mean in this situation?
b) At what value of w does the graph have a vertical asymptote? Explain how you know and what this asymptote means in the situation.
Step-by-step explanation:
t(150) = 400/570-150
=400/420
=20/21
=.95238

Answer:
PLS give me brainliest likes and 5 stars
Step-by-step explanation:
Here
Ivan wrote the ratio incorrectly. The ratio should be written as the old length to the new length, so it should be 35
10
, which reduces to 7
2
. When going from larger to smaller dimensions, the change in the scale factor is a ratio that looks like an improper fraction, with a larger number in the numerator and a smaller number in the denominator.

What is the area of triangle ABC?
Select the correct choice.
A: 6sqrt3
B: 18sqrt3
C: 36sqrt3
D: 72sqrt3
Answer:
C
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
The triangle is equilateral , since 3 angles = 60°
Then base AB = 12
Find height CD using the sine ratio in the right triangle ( there are 2 )
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{CD}{BC}[/tex] = [tex]\frac{CD}{12}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ← exact value of sin60° ( cross- multiply )
2CD = 12[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
CD = 6[tex]\sqrt{3}[/tex]
Then
A = [tex]\frac{1}{2}[/tex] × 12 × 6[tex]\sqrt{3}[/tex] = 6 × 6[tex]\sqrt{3}[/tex] = 36[tex]\sqrt{3}[/tex] units² → C
Find the possible values of k if one of the roots of the quadratic equation x^2 - kx + 8 = 0 is twice the other.
Answer:
[tex]k=\pm 6[/tex]
Step-by-step explanation:
The given quadratic equation is :
[tex]x^2 - kx + 8 = 0[/tex]
One of the roots of this equation is twice that of the other. Let the roots are [tex]\alpha \ and\ \beta[/tex], [tex]\alpha =2\beta[/tex]
Sum of roots, [tex]\alpha +\beta =\dfrac{-b}{a}[/tex]
[tex]\alpha +\beta =\dfrac{-(-k)}{1}\\\\\alpha +\beta =k\\\\3\beta =k\ .......(1)[/tex]
Product of roots,
[tex]\alpha \beta =\dfrac{c}{a}\\\\2\beta ^2=\dfrac{8}{1}\\\\\beta =\pm 2[/tex]
If [tex]\beta =\pm2[/tex],
[tex]k=3(2)\\\\=\pm 6[/tex]
So, the value of k is equal to [tex]\pm 6[/tex].

Future Amount = [?](1+[DU
what would the equation
Answer:
Future amount = 100(1.9)^5 ;
2476
Step-by-step explanation:
P(t) = P0 * (1 + r)^t
P(t) = 100 * (1 + 90/100)^t#
P(t) = 100 * (1 + 0.9)^t
Therefore, the number of bacteria in 5 years :
P(5) = 100 * (1 + 0.9)^5
P(5) = 100 * (1.9)^5
P(5) = 100 * 24.76099
P(5) = 2476.099
P(5) = 2476 bacteria

Mateo, a 31-year-old nonsmoker ($5.50), wants to purchase $100,000 in coverage for himself and $75,000 for his spouse, who is female, 30 years old, and does not smoke ($3.50). What will the insurance premium be?
A. $30.50
B. $32.50
C. $35.50
D. $36.00
Answer: B. $32.50
Step-by-step explanation:
The premiums listed in brackets are for every $25,000 of coverage.
Mateo wants a $100,000 coverage so we need to divide this by $25,000 to see how much more he will have to pay:
= 100,000 / 25,000
= 4
Mateo will have to pay 4 times the $5.50 for himself:
= 4 * 5.50
= $22.00
For his spouse who requires $75,000, he will have to pay:
= 75,000 / 25,000
= 3
= 3 * 3.50
= $10.50
Total Mateo is to pay for both his spouse and himself is:
= 22 + 10.5
= $32.50
Answer: %32.50

Nancy’s gross annual income is $46,905. She is paid monthly and has 9% deducted from her paychecks for her 403(b). Her employer matches her deduction, up to 3%.
How much is deposited into her retirement plan each payday?
Answers:
$234.52
$351.79
$469.05
$703.58
_______________
Thank you in advance!
Answer:
The amount deposited into her retirement plan each payday is;
$469.05
Step-by-step explanation:
From the details given on Nancy's income, we have;
Nancy's gross annual income = $46,905
The percentage deducted from her monthly paycheck for her 403(b) = 9%
The percentage her employer matches her deductions up to = 3%
Therefore, we have;
Her monthly pay = (Her gross annual income)÷12
∴ Her monthly pay = $46,905÷12 = $3,908.75
The amount deducted from her paycheck, A = 9% of $3,908.75
∴ A = 9/100 × $3,908.75 = $351.7875
The amount her employer matches her deductions up to, B = 3% of $3,908.75
∴ B = 3/100 × $3,908.75 = $117.2625
Therefore;
The amount deposited into her retirement plan each payday, D = A + B
∴ D = $351.7875 + $117.2625 = $469.05
The amount deposited into her retirement plan each payday, D = $469.05.

Solve the following simultaneous linear equations.
2x + y = 5
4x – 3y = -10
Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
