Here is a triangular prism.
Answer:
Volume of the prism: 120cm^3
Step-by-step explanation:
volume of a prism = area of cross-section x length
so
volume of triangular prism = 4 (h) x 6 (b) divided by 2 x 10 (length)
6 x 4 = 24
24 / 2 = 12
12 x 10 = 120

Answer:
12a. 45+0.5x+2x+x = 150
12b. the three unknown sides are 30ft, 60ft, and 15ft.
Step-by-step explanation:
12a. the fence is 150ft. so
45+0.5x+2x+x = 150
12.b solve the equation from 12a.
45+0.5x+2x+x = 150
7x/2 = 105
7x = 210
x= 30
0.5(30) = 15ft
2(30)=30ft
x= 30ft
the three unknown sides are 30ft, 60ft, and 15ft.

Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 200 adults will attend. You are trying to raise 3800 and deciding how much to charger per adult and per child. List some possible combinations (round to the nearest hundredths place) ___per adult, 0$ per child 10 per adult, ___ per child ___per child, 5$per child
Answer:
Some of the possible combinations are;
1) $19 per adult, $0 per child
2) $10 peer adult, $9 per child
3) $14 peer adult, $5 per child
Step-by-step explanation:
The given information are;
The estimated number of adults to attend the fund raising dinner = 200 adults
The amount the fund raiser is trying to realize = 3800
Therefore, some of the possible combinations are;
1) 3800/200 = 19 per adult to give;
$19 per adult, $0 per child
2) Given that each adult is charged $10, we have;
Total amount from adults = $10 × 200 = $2000
The total amount to be raised from the children = The amount the fund raiser is to realize - (Total amount from adults)
∴ The total amount to be raised from the children = 3800 - 2000 = 1800
The total amount to be raised from the children = $1,800
If there are 200 children we have;
The amount charged per child = (The total amount to be raised from the children)/(The total number of children)
The amount charged per child = $1,800/200 = $9 per child
Therefore, we have;
$10 peer adult, $9 per child
3) If each of the 200 children are charged $5 each, we have;
The total amount to be raised from the children = $5 × 200 = $1,000
∴ The amount to be raised from adults = $3800 - $1000 = $2800
The amount to each adult is to be charged = $2800/200 = $14
Therefore, we have;
$14 peer adult, $5 per child.

E is the middle of [AC]
so AE = 1/2 x AC
then
4x = 1/2 * (6x + 5)
4x = 3x + 5/2
x = 5/2
x = 2,5
Answer:
[tex]x=\dfrac52[/tex]
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other. This means that the diagonals are divided into 2 equal parts by the other diagonal.
Therefore,
[tex]\implies AE =\dfrac12 AC[/tex]
[tex]\implies 4x=\dfrac12(6x+5)[/tex]
To solve:
multiply both sides by 2:
[tex]\implies 8x=6x+5[/tex]
subtract 6x from both sides:
[tex]\implies 2x=5[/tex]
divide both sides by 2:
[tex]\implies x=\dfrac52[/tex]
When calculating a loan’s effective interest rate, if the nominal rate is 8.5%, what value of i do you plug into your equation? a. 8.5 b. 0.85 c. 0.085 d. 1.85
The value of interest rate should be 0.085.
We have given that the interest rate is 8.5% So we have given in percentage form but we use always decimal form of interest.
What is the decimal form of percentage?
To convert a percentage to a decimal, divide by 100.
So the decimal form of the 8.5% is calculated by
[tex]\frac{8.5}{100}=0.085[/tex]
Therefore the option c is correct.
Therefore we use the interest rate is 0.085.

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Please help me with this question.
The answer is:put the equation xa+yb=1 to the slope intercept form and find its slope and y-intercept.
Sample Answer: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.
Mike bought an item online for $60 and he was charged a $3 shipping fee. What percent of the sale price was the shipping fee?
Answer:
5%
Step-by-step explanation:
Given the following question:
The item costs 60 dollars
The shipping costs was 3 dollars
What was the percent of 60 is 3?
To find the answer we divide the shipping fee by the cost and then multiply the answer by 100.
[tex]\frac{3}{60} =3\div60=0.05\times100=5[/tex]

1.Solve for r in the scientific formula d= r t
2.Solve for V in the scientific formula P V= n R T
3. Solve for x in the literal equation [tex]\frac{x}{2}[/tex]-g= a
4. Solve for h in the literal equation g [tex](h+\frac{3}{2} )[/tex]=11
5. Solve for n in the literal equation a(n-2)+5=b n
Step-by-step explanation:
1. d = rt
Divide t from both sides.
[tex]\frac{d}{t} = r[/tex]
2. PV = nRT
Divide P from both sides.
[tex]V = \frac{nRT}{P}[/tex]
3. [tex]\frac{x}{2} -g=a\\[/tex]
Add g to both sides.
[tex]\frac{x}{2}[/tex] = g + a
Now multiply by 2 on both sides.
x = 2(g + a)
(or, x = 2g + 2a)
4. g[tex](h+\frac{3}{2} ) = 11[/tex]
Divide g from both sides.
[tex]h + 1.5 = \frac{11}{g}[/tex]
Now subtract 1.5 from both sides.
h = [tex]\frac{11}{g} -1.5[/tex]
5. [tex]a(n-2)+5=bn\\[/tex]
n = [tex]\frac{2a-5}{a - b}[/tex]

square root of 70 is
rational or iftationet
Answer:
Step-by-step explanation:
It's Irrational.
sqrt(70) = sqrt(2 * 5 * 7)
You can't pull anything out of the right to leave the number under the root sign = to 1. That means that since all three roots are irrational, the whole number is irrational, In fact it takes only 1 number other than 1 left under the root sign to make the result irrational.
√50 = √(5 * 5 * 2)
The 5's will produce one number outside the root sign -- five. That makes the result
5√2 The result is irrational because √2 is irrational
