A triangular prism is shown. A cylinder is cut out of the center of the prism. The triangular base has side lengths of 14 and 10 units. The heights of both the cylinder and prism are 8 units. The cylinder has a diameter of 5 units.
Which expression represents the volume, in cubic units, of the shaded region of the composite figure?
One-half(14)(10)(8) – π(2.52)(8)
One-half(14)(10)(8) + π(2.52)(8)
One-third (one-half)(10)(8)(14) – π(2.52)(8)
One-third (one-half)(10)(8)(14) + π(2.52)(8)
The expression that represents the volume, in cubic units, of the shaded region of the composite figure is option: A. One-half(14)(10)(8) – π(2.52)(8).
How to find the volume of a prism?If the prism is such that if we slice it horizontally at any height smaller or equal to its original height, the cross-section is same as its base,
then its volume is:
V = B x h
where h is the height of that prism and B is the area of the base of that prism.
Given:
Base side length =14 and 10 units
Height=8 units
Diameter=5 units
The volume of the shaded region is;
Expression = 1-( half 14)(10)(8) - π(2.52)(8)
Expression = 1-(7) (10)(8) - π(2.52)(8)
Expression = 1- (560)- 63.33
Expression = -559-63.33

If £2000 is placed into a bank account that pays 3% compound interest per year
how much will be in the account after 2 years?
Answer:
£ 2121.8
Step-by-step explanation:
The formula to find the compound interest is :
[tex]A=P(1+\frac{R}{100} )^n[/tex]
Here,
A = Amount ⇒ ?
P ⇒ Principal ⇒ £2000
R ⇒ Interest rate ⇒ 3%
n ⇒ Time ⇒ 2 years
Let us find now.
[tex]A=P(1+\frac{R}{100} )^n[/tex]
[tex]A=2000(1+\frac{3}{100} )^2[/tex]
[tex]A=2000(1+0.03 )^2[/tex]

solve log base 6 (x-6) - log base 6 (x + 4) = 2
Answer:
no solutions
Step-by-step explanation:
Since the two terms have the same base, we are able to use the rule for subtracting logarithms:
[tex]log_{b}(x) - log_{b}(y) = log_{b}(\frac{x}{y} )[/tex]
Therefore, the equation can be written as:
[tex]log_{6}(\frac{x-6}{x+4} )=2[/tex]
By using the definition of a logarithm we can say that:
[tex]\frac{x-6}{x+4} = 6^{2}\\\frac{x-6}{x+4} = 36\\x -6 = 36x+144\\35x = -150\\x =-\frac{30}{7}[/tex]
When plugging this solution in, you find that the term [tex]log_{6}(x-6)[/tex] has x-6 evaluate to a number less than 0. This is not included in the domain of log functions, so [tex]-\frac{30}{7}[/tex] is not a valid solution. This means that there are no solutions.

mark, what is the score of Faith
Answer:
Let Musa's mark be = m

b. many solutions
c. No solution
d.(17,20)
An equation is formed of two equal expressions. The value of x and y is 17 and 20, respectively. Thus, the correct option is D.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Solving the first equation for y,
4x - 3y = 8
-3y = 8 - 4x
y = (8-4x)/(-3)
Solving the second equation for y,
5x - 4y = 5
-4y = 5 - 5x
y = (5 - 5x)/(-4)
Equate the value of y,
y = y
(8-4x)/(-3) = (5 - 5x)/(-4)
-32 + 16x = -15 + 15x
16x - 15x = -15 + 32
x = 17
Substitute the value of x in any one of the equation,
4x - 3y = 8
4(17) - 3y = 8
68 - 3y = 8
-3y = -60
y = 20
Hence, the value of x and y is 17 and 20, respectively. Thus, the correct option is D.

Drag each label to the correct location on the triangle. Not all labels will be used.
Find the unknown measurements. Round all values to the nearest tenth.
cm
8.9 cm
65°
Answer:
long side: 19.1 cmmissing angle: 25°hypotenuse: 21.1 cmStep-by-step explanation:
You can use this information to "guess" at the answers without doing any "work."
The sum of angles in a triangle is 180°.The shortest side is opposite the smallest angle.__
qualitative solutionThe missing angle is the complement of the marked acute angle in the right triangle, so is ...
C = 90° -65° = 25°
This angle is opposite the side of length 8.9 cm. The next-smallest angle is 65°, which is more than double the smallest angle. Hence the side opposite 65° will not be either of 3.8 or 9.8.
Of the two remaining measures, the longer one, 21.1, will be the hypotenuse, BC. The shorter of those, 19.1, will be the long side, AC.
Our solution is ...
AC = 19.1 cmC = 25°BC = 21.1 cm__
quantitative solutionThe mnemonic SOH CAH TOA reminds you of the relations between trig functions and right triangle sides. Here, we're given an angle and the length of its adjacent side. We are asked for the opposite side and for the hypotenuse. This suggests useful relations might be ...
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Solving the first of these for the hypotenuse gives ...
hypotenuse = adjacent/cos(65°)
BC = 8.9 cm/cos(65°) ≈ 21.059 cm ≈ 21.1 cm
Solving the second relation above for the opposite side gives ...
opposite = adjacent×tan(65°)
AC = 8.9 cm×tan(65°) ≈ 19.086 cm ≈ 19.1 cm
As above, the missing angle is the complement of the given one:
C = 90° -65° = 25°
Then the quantitative solution is ...
AC = 19.1 cmC = 25°BC = 21.1 cm_____
Additional comment
If AC were 9.8 cm, the angle at B would be about 48°. That is, the two acute angles in the triangle would be very nearly equal.
We know that the side ratios in a 30°-60°-90° right triangle are 1 : √3 : 2. This triangle has a larger angle greater than 60°, so its longer side will be more than √3 times the short side. That means a length of 9.8 cm is way too short.
Jose is 35 years old, and makes $40,000 per year. If he dies, how much would
the beneficiaries of his life insurance policy receive if they can get by on 75% of
his income?
The amount that the beneficiaries of his life insurance would receive would be $30000.
How to solve for the amount that would be receivedThe total amount of insurance is 40000
percentage needed by beneficiaries on this amount = 75%
Hence 75% * 40000
= $30000
Therefore it can be concluded that the amount that the beneficiaries would require on 75% is $30000.

The year, where the number of cars sold exceed 46,000 is 13496
How to determine the year?The equation of the function is given as:
y = 4x + 2
When the sales exceed 46000;
It means that y > 46000
So, we have:
4x + 2 > 46000
Subtract 2 from both sides
4x > 45998
Divide both sides by 4
x > 11499.5
The year is then calculated as:
Year = 1996 + x
So, we have:
Year > 1996 + 11499.5

Writing One Variable Algebraic
Expressions
Leslie buys a new pair of sneakers for $43 and several
pairs of laces, I, that cost $6 each. Write an algebraic
expression to represent the total amount she will spend.
Answer:
y = 6l + 43
Step-by-step explanation:
y=mx + b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
The y intercept is when x = 0, so the initial cost before buying the laces, which was the cost of the sneakers
b = 43
The slope is you purchase one pair of laces, it increases by 6 each time
m = 6
The y coordinate will represent the total cost spent
y
The x coordinate will represent the total number of laces purchase and we are told that the variable is l
x = l
combine:
y = 6l + 43
