Tristan had 1/3 lb of grapes at home he went to the store and bought 3/8 lb of grapes what fraction of a pound of grapes does Tristan have now explain
Answer:
Tristan has a 17/24 lb fraction of a pound of grapes now.
Step-by-step explanation:
Given
The number of grapes Tristan had at home = 1/3 lbThe number of grapes Tristan had at the store = 3/8 lbTo determine
What fraction of a pound of grapes does Tristan have now?
In order to get the total fraction of a pound of grapes, all we need is to add the number of grapes Tristan had at home and the number of grapes Tristan had at the store.
i.e.
Current number grapes = 1/3 + 3/8
Least Common Multiple of 3, 8: 24
Adjust fractions based on L.C.M
= 8/24 + 9/24
Apply the fraction rule: [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]
= (8 + 9) / 24
= 17/24 lb
Therefore, Tristan has a 17/24 lb fraction of a pound of grapes now.

Determine the volume of the three-dimensional figure.
Answer:
12 cm^3
Step-by-step explanation:
multiply all three numbers
Answer:
Step-by-step explanation:
Multiply the three measurements together to find the volume using either paper and pencil or a calculator. This is the equation: Volume = length x width x height. For example, if the measurements of your prism are 6 inches, 5 inches and 4 inches, the equation would look like this: Volume = 6 x 5 x 4.

What is the solution to the system of equations below?
Y=-3x+5 and y=4x-2
9514 1404 393
Answer:
(x, y) = (1, 2)
Step-by-step explanation:
You can solve this by subtracting the first equation from the second.
(y) - (y) = (4x -2) -(-3x +5)
0 = 7x -7 . . . . . .simplify
0 = x -1 . . . . . . . divide by 7
1 = x . . . . . . . . . .add 1
Use the first equation to find y:
y = -3(1) +5
y = 2
The solution is (x, y) = (1, 2).

Thank you sooooooooooooo. Much
Answer:
24 inches
Step-by-step explanation:
Similar to the question you asked earlier, this question also has 3 small rectangles and we can combine it to make it a one big rectangle. The equation for the perimeter is this:
2W + 2L = P
We know W and P (the width of the small rectangles times 3), thus plugging in those values would give us:
2(30*3) + 2L = 324
180 + 2L = 324
2L = 144
L = 72
We need to divide this number by 3 to get the length of the small rectangle, which would give us 72/3 or 24.

Help plz
To make this problem solvable, I have replaced the 't' in the second equation for a 'y'.
Answer:
x = -9
y = 2
Step-by-step explanation:
Solve the system:
2x + 3y = -12 [1]
2x + y = -16 [2]
Subtracting [1] and [2]:
3y - y = -12 + 16
2y = 4
y = 4/2 = 2
From [1]:
2x + 3(2) = -12
2x + 6 = -12
2x = -18
x = -18/2 = -9
Solution:
x = -9
y = 2

Find the sales tax and cost of a PS5 that costs $499. The tax rate is 7.25%. Round your answer to
the nearest cent.
a. What is the sales tax?
b. What is the total cost?
Step-by-step explanation:
First make an equation.
y=0.0725(499)
This equation would solve for the sales tax.
y=36.1775 or 36.18 because you have to round it l.
To find the total cost, you would do 499+36.18= $537.18

Answer:
what is your question?
Well, if I can remember correctly-
1.) (c^2 +4c) I believe you would rewrite in factored form to get a solution of c(c + 4)
2.) (4w^2 -4) I think you would the 4w^2 first, getting 16w. Then the solution would be 16w - 4 (since you cannot combine these terms together)
3.) (z^2 - 2z) You would do the same with this as you would with question 1, which would give you a solution of z(z + 2)

1/3 -shade the hexagon to show the fraction. The confusion is now to shade when the denominator isn’t 6...
What should be shaded for 1/3.
Answer:
Step-by-step explanation:
Let's understand this problem with an example.
[tex]\frac{1}{3}[/tex] fraction of a cake defines one part taken out of total 3 parts of the cake.
If this cake is divided in 6 parts, [tex]\frac{1}{3}[/tex] of the cake will be defined by the two parts parts chosen out of 6 parts of the cake.
Algebraically we represent this phenomenon with,
[tex]\frac{1}{3}=\frac{1\times 2}{3\times 2}=\frac{2}{6}[/tex]
Therefore, color two parts out of 6 to represent [tex]\frac{1}{3}[/tex]

All cubes have six faces. Likewise, the cube shown above also has 6 faces.
[tex]\color{plum}\tt \: Answer \: \: part \: \: 2 :[/tex]
Length of side of one face of cube = 3 inches
Area of one face :

= 3 × 3
= 9 inch²
Therefore, the area of one face of this cube = 9 inch²
[tex]\color{plum}\tt \: Answer \: \: part \: \: 3 :[/tex]
Area of cube = sum of the area of all faces
Then, the area of this cube :
