Answer:[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
With unlike denominators find the Least Common Denominator (LCD)
LCD = 12
Multiplying numerators and denominators to get the LCD in all fraction denominators
[tex]=\frac{3x3}{4x3}-\frac{1x4}{3x4}+\frac{1}{12}[/tex]
Then rewriting the equation with the equivalent fractions
[tex]=\frac{9}{12}-\frac{4}{12}+\frac{1}{12}[/tex]
With like denominators we can operate on just the numerators
[tex]=\frac{9-4+1}{12} =\frac{6}{12}[/tex]
Simplifying the answer
[tex]=\frac{1}{2}[/tex]

PyramidRectangular PrismCylinderConeTriangular Prism==============================================
Explanation:
The formula for the volume of a pyramid is (1/3)*B*h, where B is the area of the base. If we're dealing with a rectangular pyramid, like those found in Egypt, then the area of the base is B = length*width. The volume for a prism is found by multiplying length (L), width (W), and height (H). So V = LWH. Think of having a 2 by 3 rectangle of blocks. We would have 2*3 = 6 blocks in total. Then if we have 5 layers of these stacked then we have 2*3*5 = 6*5 = 30 blocks in total. This is one way to visualize how the volume formula works.To get the volume of a cylinder, we multiply the area of the base (pi*r^2) by the height (h). So that's where pi*r^2*h comes from.The volume of a cone is 1/3 that of a cylinder's volume. This is when the cone and cylinder have the same radius, and also the same height. It's not required that r = h.Since all of the other answer choices are used up, the only thing left is "triangular prism". It's strongly implied here that B is the area of the triangular base. Though the formula Bh applies to any prism and it doesn't have to be a triangular prism. Note how B = LW, so Bh is the same as LWH, meaning that a rectangular prism can use the Bh formula.Question 4 (1 point)

Write an equation that represents the total cost for pop music bundles. Write another equations to represent the total cost for rock music bundles. Identify the variables in the equations.
Answer:
Equation for the total cost for pop music bundles = $ 1200 x + 300
Where variable is the Cost.
Equation for the total cost for rock music bundles = $ 950 x + 250
Where variable is the Cost.
Step-by-step explanation:
P.S - The exact question is -
Given - The Music Express is going to buy music bundles from a
company that is going out of business. The company
charges different amounts for bundles of pop and rock
music:
Cost for each pop music bundle is $1200
Cost for each rock music bundle is $950
One - time fee for rights to the pop music is $300
One - time fee for rights to the rock music is $250.
To find - Write an equation that represents the total cost for pop
music bundles.
Write another equations to represent the total cost for rock
music bundles.
Identify the variables in the equations.
Proof -
Given that,
Cost for each pop music bundle is $1200.
Cost for each rock music bundle is $950.
One - time fee for rights to the pop music is $300.
One - time fee for rights to the rock music is $250.
Let the total music bundles buy = x
Now,
Given, Cost for 1 pop music bundle = $1200
⇒Cost for x pop music bundles = $ 1200 x
Also given,
One - time fee for rights to the pop music is $300.
∴ we get
Equation for the total cost for pop music bundles = $ 1200 x + 300
Where variable is the Cost.
Now,
Given, Cost for 1 rock music bundle = $950
⇒Cost for x pop music bundles = $ 950 x
Also given,
One - time fee for rights to the pop music is $250.
∴ we get
Equation for the total cost for rock music bundles = $ 950 x + 250
Where variable is the Cost.

Find the value of x when (a) 9 : x : : 54 : 48 (b) 2, 6 , x are in continued proportion
Answer:
a) x = 8
b) x = 18
Step-by-step explanation:
Given that
9 : x : : 54 : 48
This may be rewritten as
9/x = 54/48
cross multiply
9 * 48 = 54 * x
Divide both sides by 54
x = 9 * 48/54
= 8
b Given that 2, 6, x are in continued proportion then
2/6 = 6/x
2 * x = 6 * 6
x = 36/2
= 18

Jordan went to shelter to adopt a dog. There were 10 brown dogs and 10 black dogs. Jordan picked a dog, went home, then decided he wanted to go back and adopt another dog. What is the probability that he picked two black dogs?
A. 10/20
B. 9/19
C. 1/2
D. 9/38
B. 9/19
Step-by-step explanation:
there was 20 dogs in total he took 1 black dog now 19 in total, now 9 black dogs and 10 brown dogs so one less probability of black dogs so 9 black dogs and 10 brown dogs so 9/19

3. Jaselle earned $80.00 raking leaves. This is 8 dollars more than 4 times the amount that Dillon
earned. How much did Dillon earn?
(25 Points)
Answer:
Step-by-step explanation:
So, Jaselle has $80.00.
This is 8 dollars more than 4 times the amount that Dillon
earned.
$80.00 - 8.00 = $72.00
4 Times average amount = $72.00
Average (begining amount) = $18.00

Answer:
(-2, 6)
Step-by-step explanation:
Plug in one of the equations into the y-variable (doesn't matter which):
2x + 10 = -4x - 2
Combine like terms by adding the 4x to both sides. This makes it cancel out on the right side, and 2x + 4x on the right side is 6x:
6x + 10 = -2
Combine like terms by subtracting 10 from both sides, making it cancel out on the left side, and on the right: -2 - 10:
6x = -12
Then isolate the x-variable by dividing both sides by 6:
x = -2
Taking the -2, plug it into an x-variable in either of the equations:
y = 2x +10
y = 2(-2) + 10
y = -4 + 10
y = 6
write the expression in exponential form.

Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall.
Complete question :
Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall. Find the number of block letters that will fit in the box.
Answer:
1/2
Step-by-step explanation:
Number of block letters that will fit in :
Volume of box ÷ volume of each letter cube
Volume of each letter cube = (side length)³ = (2/3)³ = 8/27 ft³
Volume of box = length * width * height
Volume of box = 1 1/3 * 2/3 * 2/3
Volume of box = 4/3 * 2/3 * 2/3 = 16 / 27 ft³
Therefore ;
8/27 ÷ 16/27
8/27 * 27/16
= 8/16
= 1/2
