Answer:
24 [tex]m^{3}[/tex]
Step-by-step explanation:
Volume=l*b*h
as tank is half full so height of water will be 4m
and Voulme will be,
V=3*2*4=24 [tex]m^{3}[/tex]
while capacity of tank is,
V=3*2*8=48 [tex]m^{3}[/tex]
The volume of water in the tank, when it is half full, is 24 cubic meters.
What is volume?Volume in mathematics and physics refers to how much three-dimensional space is occupied by a substance or an object. It is a measurement of the overall volume of space contained inside a three-dimensional object's limits.
The volume of the rectangular tank is given by the formula:
V = l x b x h
where l is the length, b is the breadth, and h is the height of the tank.
Substituting the given values, we get:
V = 3m x 2m x 8m = 48 cubic meters
If the tank is half full, then the volume of water in the tank is:
Vw = (1/2) * V = (1/2) x 48 = 24 cubic meters
Therefore, the volume of water in the tank when it is half full is 24 cubic meters.

Emily recently started a part time job. She is saving for a car, which she will need when she attends college next year. She plans to deposit $400 at the end of each month into an account that 3.6% per year, compounded monthly . How much will Emily have saved at the end of six months? pays
Answer:
$2418.07
Step-by-step explanation:
Problems involving the time-value of money are conveniently solved using a TVM app on a suitable calculator or spreadsheet. The result of doing that is shown in the attachment.
__
If you would like to compute the value of Emily's account by hand, the annuity formula is the one you want.
A = Pn((1 +r/n)^(nt) -1)/r . . . . where r is the annual interest rate, n is the number of times per year it is compounded (12), t is the number of years (1/2), and P is the periodic payment into the acccount (400).
Using the given values in the formula, we have ...
A = 400(12)((1 +0.036/12)^(12/2) -1)/0.036 = 4800×(1.003^6 -1)/0.036
A ≈ 2418.07
At the end of 6 months, Emily will have saved $2418.07.

Answer:
About 154 Square
Explanation:
To find an area of a circle you multiply pi by the radius squared so 7² = 49 and 49 x 3.14 = 153.86 which is the closest to 154.
Dr. Weinstein took 50 ounces of a 20% silver
alloy and mixed it with a 40% silver alloy to get
a 30% silver alloy. How many ounces of the 40%
silver alloy did he use?
Answer:
I think it is 100
Answer:
Step-by-step explanation:
The answer is 50 ounces
Because 30% silver is right in between 20% silver and 40% silver, it would have to be the same amount to be 30%
1. How many degrees are in this angle, which is one-fourth of the circle?
Answer: 90 degrees
Step-by-step explanation: A circle is 360 degrees so since that is 1/4 you can divide
360/4 = 90 (: hope this helps
Answer:
90* x 4 = 360*
360* / 4 = 90*
Step-by-step explanation:
A circle has 360* all around.
In the angle that was drawn, it is 90*
The degrees for the space outside of 90* is x
x = ? 360* - 90* = 280* x = 280*

what's the estimate of 6.48 + 9.34 and what's the estimate 15.71 + 12.2
Answer:
Your Estimated Equations and Answers: 6+9= 15 ; 16+12 = 28
Step-by-step explanation:
Estimating can be equivalent to rounding. This is because you're trying to find an approximate number or sum.
6.48 + 9.34 is your first question.
You should round it to the nearest whole number.
6.48 ~ 6 and 9.34 ~ 9
*Rounding rules applied here*
(~ this sign is the approximate or rounded to symbol)
Now, do 6+9 =
6+9= 15
______________________________________________
15.71 + 12.2 is your next question.
Same as last, round to the nearest whole number.
15.71 ~ 16 and 12.2 ~ 12
Now, do 16+12
16+12 = 28

Solve the following quadratic by
completing the square.
f(x) = x2 + 10x - 1
Answer:
x = -5 plus/minus sqrt( 26 )
Step-by-step explanation:
Let's remember the binomial square formula
A^2 + 2AB + B^2 = (A + B)^2
We have:
x^2 + 2*5x -1
Hence, if we replace
A = x
B = 5
we get a perfect square: x^2 + 2*5x + 25 = (x + 5)^2. [++]
Based on this reasoning, let's set f(x) = 0
x^2 +10x -1 = 0
Let's add 26 on both terms:
x^2 +10x +25 = 26
Based on [++]: (x + 5)^2 = 26
Square root on both sides
(x + 5) = plus/minus sqrt (26)
x = -5 plus/minus sqrt (26)
When you multiply a whole number by 10 to the 5th power , will there always be the same number of
zeros before the decimal point as in your answer to Part A? Explain your reasoning.
Answer:
Answer:
Step-by-step explanation:
a whole number can be ANY counting number
10 to the 5th power = × 10 × 10 × 10 × 10 × 10
when you multiply by any positive power of ten, you are making it really big
23 × 10 × 10 × 10 × 10 × 10 = 2,300,000
30 × 10 × 10 × 10 × 10 × 10 = 3,000,000
100 × 10 × 10 × 10 × 10 × 10 = 10,000,000
the pattern is the whole number followed by 5 zeros that show 5 place values

find the sum of the fractions below. 5/8 + 1/n = 7/8 A. 3 B. 3 5/12 C. 3 4/9 D. 4
Answer:
D. 4
Step-by-step explanation:
1) Subtract 5/8 from both sides.
1/n = 7/8 - 5/8
2) Simplify 7/8 - 5/8 to 1/4.
1/n = 1/4
3) Multiply both sides by n.
1 = 1/4n
4) Simplify 1/4n to n/4.
1 = n/4
5) Multiply both sides by 4.
1 * 4 = n
6) Simplify 1 * 4 to 4.
4 = n
7) Switch sides.
n = 4
Check Answer:
5/8 + 1/n = 7/8
1) Let n = 4.
5/8 + 1/4 = 7/8
2) Simplify 5/8 + 1/4 to 7/8.
7/8 = 7/8

Find
a
and
d
for an arithmetic sequence where the 5th term is 10 and the 6th term is 8.
Answer:
Step-by-step explanation:
Arithmetic sequence:
[tex]\boxed{a_n =a + (n-1)*d)}[/tex]
a₅ = 10 a + 4d = 10
a₆ = 8 a + 5d = 8
Multiply the equation (I) by (-1) and then add. 'a' will be eliminated and we can find the value of 'd'
(I)*(-1) -a - 4d = -10
(II) a + 5d = 8 {Now add}
d = -2
Substitute d = -2 in equation (I)
a + 4*(-2) = 10
a - 8 = 10
a = 10 + 8
a = 18
a = 18 , d = -2
Sequence: 18 ,16 , 14 , 12 , 10 , ......

Find an equation of the line that goes through the points (8,-45) and (2,-9). Write your answer in the form y = mx + b.
Linear equations are commonly organized in slope-intercept form:
[tex]y=mx+b[/tex]
m = slopeb = the y-intercept (the value of y when x=0)To find the equation of a line given two points:
Determine the slope of the line using the slope formulaPlug the slope into [tex]y=mx+b[/tex]Determine the y-intercept by solving for bPlug the y-intercept back into the equationSolving the QuestionWe're given:
The line passes through the points (8,-45) and (2,-9)First, determine the slope using the following formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
⇒ Plug in the given points (8,-45) and (2,-9):
[tex]m=\dfrac{-45-(-9)}{8-2}\\\\m=\dfrac{-45+9}{8-2}\\\\m=\dfrac{-36}{6}\\\\m=-6[/tex]
Therefore, the slope of the line is -6. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=-6x+b[/tex]
Now, determine the y-intercept:
[tex]y=-6x+b[/tex]
⇒ Plug in one of the given points as (x,y) and solve for b:
[tex]-9=-6(2)+b\\-9=-12+b\\3=b[/tex]
Therefore the y-intercept of the line is 3. Plug this back into [tex]y=-6x+b[/tex]:
[tex]y=-6x+3[/tex]
Answer[tex]y=-6x+3[/tex]
