Find the value of x in each of the following
a) x/3-2 = 6
b) x/5+ 1 = 5
Answers
A)
X/3 -2 = 6
Add 2 to both sides:
X/3 = 8
Multiply both sides by 3:
X = 24
B)
X/5 +1 = 5
Subtract 1 from both sides:
X/5 = 4
Multiply both sides by 5:
X = 20
Answer:
a) 24.
b) 20.
Step-by-step explanation:
a) x/3 - 2 = 6
x/3 = 6 + 2 = 8
x = 3*8
x = 24.
b). x/5 + 1 = 5
x/5 = 5 - 1 = 4
x = 5*4
x = 20.

CB. The volume of prism A is less than the volume of prism B.
C. The volume of prism A is the same as the volume of prism B.
D. The volume of prism A is greater than the volume of prism B.
Answers
Answer:
There is not enough information to compare the volume of the prisms.
Step-by-step explanation:
To find the volume of rectangular prisms, the length , width and height must be given. The volume of rectangular prisms is gotten by multiplying the three dimension: length, width and height which is expressed in cubic units. To compare the two volumes, the three dimensions must be given.
Hence, there is not enough information to compare.
Ma poate ajuta cineva la acesta problema: pe o drepta g considerati punctele D, R,P si T coliniare in aceasta ordine astfel incat DR=PT=3 cm, iar RP=4cm
Answers
Answer:

[tex]DR=PT=3cm[/tex] and [tex]RP=4cm[/tex]
Points D, R, P and T are collinear.
The image attached shows a representation of this problem.
By sum of segments, we have
[tex]DT=DR+RP+PT[/tex]
Replacing all given values, we have
[tex]DT=3+4+3=10 \ cm[/tex]
Therefore, the segment DT is 10 centimeters long.
Now, we know that point E is the center of segment RP, which means is a middle point, divides the segment equally. So, to prove that segment DT is symmetrical regarding point E, we need to prove that both sides are equal.
[tex]RE=EP=2cm[/tex], by definition of middle point.
By sum of segments, we have
[tex]DR+RE=3+2=5cm\\EP+PT=5cm[/tex]
Which means [tex]DR+RE=\frac{DT}{2}\\ EP+PT=\frac{DT}{2}[/tex].
Therefore, segment DT is symmetrical regarding point E.

find all solutions to the equation 5sin(3pix)+8=4 in the interval 0 < x < 2
Answers
Answer:
First one
Step-by-step explanation:
5sin(3pix)+8=4
5sin(3pix) = -4
sin(3pi x) = -0.8
Basic angle: sin^-1(0.8) = 0.927295218
3pi x = pi+0.927295218, 2pi-0.927295218
3pi x = 4.068887872, 5.355890089, 4.068887872 + 2pi, 5.355890089 + 2pi, 4.068887872 + 4pi, 5.355890089 + 4pi,
x = above values/3pi
x = 0.43217, 0.568, 1.0984, 1.235, 1.765, 1.9016

Answers
Answer:
x=((log(81))/(log(3))+2)/3
Step-by-step explanation:
so what you want to do is get 3x-2 out of the exponent
you can do that by using log
so apply log to both sides and you get
log(81)=(3x-2)log(3)
the 3x-2 is moved in front of the log due to a log rule
then (log(81))/(log(3))=3x-2
(log(81))/(log(3))+2=3x
((log(81))/(log(3))+2)/3=x
then use a calculator to find the exact value

Jack bought an automatic water bottle feeder for his cat. A diagram of the bottle is shown below. What is the maximum amount of water that the bottle can hold?
Answers
Answer:
my best guess even though no answers i would say bout 12
Step-by-step explanation:
The maximum amount of water that the bottle can hold is approximately 263.8938 cubic inches.
What is a cone?A cone is a three-dimensional geometric form with a flat base and a smooth, tapering apex or vertex. A cone is made up of a collection of line segments, half-lines, or lines that link the base's points to the apex, which is a common point on a plane that does not include the base.
To find the maximum amount of water that the bottle can hold, we need to calculate the volumes of the cylinder and the cone and add them together.
The volume of the cylinder:
V_cylinder = πr²h
where r is the radius (half of the diameter) of the base, and h is the height of the cylinder.
The radius of the cylinder base is 6/2 = 3 inches, and the height of the cylinder is 8.5 inches, so:
V_cylinder = π(3)²(8.5)
V_cylinder ≈ 226.1947 cubic inches
Volume of the cone:
V_cone = (1/3)πr²h
where r is the radius of the base of the cone, and h is the height of the cone.
The radius of the base of the cone is also 3 inches, and the height of the cone can be found by subtracting the height of the cylinder from the total height of the bottle:
h_cone = total height - height of cylinder = 12.5 - 8.5 = 4 inches
So:
V_cone = (1/3)π(3)²(4)
V_cone ≈ 37.6991 cubic inches
Total volume:
V_total = V_cylinder + V_cone
V_total ≈ 226.1947 + 37.6991
V_total ≈ 263.8938 cubic inches
Therefore, the maximum amount of water that the bottle can hold is approximately 263.8938 cubic inches.

Financial Literacy: Question 2Gordon opened a savings account with an initial deposit of $1,200.His balance will earn 2.5% simple interest overy year, Balley openeda savings account with an initial deposit of $900. Her balance willearn 3.25% interest compounded annually. The deposits were madeon the same day, and no additional money will be deposited orwithdrawn from the accounts. Which statement about the balances ofGordon's account and Balley's account at the end of 6 years is true?
Answers
Answer:
In 6 years form now, the balance in Gordon's account will be = {$1,200 x [1 + (2.5% x 6 years)]} = $1,380
his account will have earned = 2.5% x 6 years x $1,200 = $180 in interests over the six years
In 6 years form now, the balance in Bailey's account will be = $900 x (1 + 3.25%)⁶ = $1,090.39
his account will have earned = $190.39 in interests over the six years
Bailey's account earned more interest than Gordon's, even though his initial balance was much lower. This was due to higher interest rates and more important, because Bailey earned compound interest.

In ΔABC, ∠B = 90°, AB = 9 cm and BC = 12 cm. Calculate the length of AC. and area of triangle ABC
Answers
Answer:
see explanation
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AC² = AB² + BC² , substitute values
AC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )
AC = [tex]\sqrt{225}[/tex] = 15 cm
-------------------------------------------
The area of Δ ABC is calculated as
A = [tex]\frac{1}{2}[/tex] × BC × AB = [tex]\frac{1}{2}[/tex] × 12 × 9 = 6 × 9 = 54 cm²

What does a probability simple definition entail?
A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%. Probability is a measure of how likely or likely-possible something is to happen.
For instance, the chance of flipping a coin and obtaining heads is 1 in 2, as there is only one method to acquire a head and there are a total of 2 potential outcomes (a head or tail). P(heads) = 12 is the formula.

If you wanted to safely climb a 50-foot wall, what’s the shortest ladder you’d be willing to use? Explai
Answers
Answer:
If I wanted to safely climb a 50 foot wall, I would use a 51 foot ladder.
Step-by-step explanation:
If I wanted to climb a fifty foot (50 ft) wall, I would use a fifty one foot (51 ft) ladder because the safe way to position a ladder against the wall requires that I leave one foot (1 ft) distance from the base of the ladder to the wall. That way, the ladder won't be too close nor too far from the wall.
