Sofia mixed 3.15 L of grape juice with 4.75 L of cranberry juice. Her friends drank 3.95 L of the juice mixture.
How much juice was left over?
Answer: The amount left over was 4.05 L.
Estimation: 3.15 + 4.75 is about 7.
7 L – 4 L = 3 L
The amount left over was about 3 L.
Answer: The amount left over was 11.85 L.
Estimation: 3.15 + 4.75 is about 8 L.
8 L + 4 L = 12 L.
The amount left over was a little less than 12 L.
Answer: The amount left over was 3.95 L.
Estimation: 3.15 + 4.75 is about 8.
8 L – 4 L = 4 L
The amount left over was a little less than 4 L.
Let's go through each answer.
A.
Answer: The amount left over was 4.05 L.
Estimation: 3.15 + 4.75 is about 7.
7 L – 4 L = 3 L
The amount left over was about 3 L.
This is incorrect because 3.15+4.75 is closer to 8 than 7.
B.
Answer: The amount left over was 3.95 L.
Estimation: 3.15 + 4.75 is about 8.
8 L – 4 L = 4 L
The amount left over was a little less than 4 L.
This is correct because 3.15+4.75 is close to 8 and to find the amount left over you do have to subtract.
The correct answer is B.
Answer: The amount left over was 3.95 L.
Estimation: 3.15 + 4.75 is about 8.
8 L – 4 L = 4 L
The amount left over was a little less than 4 L.

There's 2 questions here that need to be answered.
Find the value of each variable.
Answer:
5. x= 13 y= 18.4
6.
Step-by-step explanation:
question 5:
tan45=x/13
multiply both sides by 13 to get x by its self.
end up with 13×tan45 so put that in the calculator to get x
then you do cos45= 13/y
multiply by y on both sides.
end up with y×cos45=13
divide the cos45 by both sides
put 13/cos45 to get y
question 6:
sin30=4/x
multiply x on both sides
end with x×sin30 =4
divide sin30 on both sides
put 4/sin30 in a calculator to get x
same thing again but with tan30 ahaha
What is the equation of the line that passes through the point (- 1, 5) and is parallel to the line y = - 3x + 5
Answer:
y - 5 = -3(x + 1)Step-by-step explanation:
Parallel lines has the same slope.
The equation of a line that passing through point (x₁, y₁) with a slope of m is:
y - y₁ = m(x - x₁)
m = -3
(-1, 5) ⇒ x₁ = -1, y₁ = 5
Therefore the equation:
y - 5 = -3(x + 1)
Convert the fraction below into a percent: 9/15
Answer:
Your answer will be 60%
Step by Step explanation:
W know the GCF(greatest common factor) of 9 and 5 is 3 so
9÷3=3 15÷3=5 which make 3/5
We know that
3/5
is the same as
3÷5
Then using
Long Division for 3 divided by 5 gives us
0.6
Converting our number to a percentage:
0.6×100
=60%

What is the volume to the nearest integer
Answer:
C
Step-by-step explanation:
Type the correct answer in each box.
,
then a = and b = .
Answer:
a = 0, b = -15
Step-by-step explanation:
Given the following complex number;
x1 = 3(cosπ+isinπ)
x2 = 5(cosπ/2 - isinπ/2)
x1x2 = 15(cosπcosπ/2 - icosπsinπ/2+isinπcosπ/2 -i²sinπsinπ/2)
x1x2 = 15(0 - i(-1)+0 -0)
x1x2 = 15(-i)
x1x2 = -15i
x1x2 = 0-15i
Since
0 - 15i = a+ bi
Compare
a = 0
-15- = bi
b = -15
Hence a = 0, b = -15

water?
Answer:
Volume of cylinder = 1,156.57 cm³
Step-by-step explanation:
Given:
Radius R = 4 cm
Height of cylinder = 23 cm
Find:
Volume of cylinder
Computation:
Volume of cylinder = πr²h
Volume of cylinder = (22/7)(4)²(23)
Volume of cylinder = (22/7)(16)(23)

A pumpkin patch charges a $5 entrance fee and $0.60 per pound for pumpkins. Which of the following represents the cost C, In dollars, for one person to enter the pumpkin patch and pick x pounds of pumpkin?
Answer:C=5+0.6x
Step-by-step explanation:
The equation that represents the total cost will be C = 0.60x + 5.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
A pumpkin patch charges a $5 entrance fee and $0.60 per pound for pumpkins.
Let x be the number of pounds of pumpkin and C be the total cost in dollars.
Then the equation that represents the total cost will be
C = 0.60x + 5
The equation that represents the total cost will be C = 0.60x + 5.

Mathematically;
we have a structure like an arc of a circle. It is the length of this arc we want to calculate.
The formula for the length of an arc is;

Jim and bill each invest $15,000 into savings accounts that earn 3.5% interest. Jims account earns simple interests and bills account earns compound interest. After 25 years, who will earn more interest and how much more will he earn.
Answer:
Bill will earn more interest
He will earn $ 20,448.67 from his investment
Step-by-step explanation:
Firstly let us calculate Jim's earnings based on simple interest
A = P(1 + rt)
Calculation:
First, converting R percent to r
a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
Solving our equation:
A = 15000(1 + (0.035 × 25)) = 28125
A = $28,125.00
The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim
Now let's us calculate bill's investment based on compound interest
Equation
A = P(1 + r)^t
A=15000(1+0.035)^25
A=15000(1.035)^25
A=15000*2.36324498427
A = $ 35,448.67
We see that Bill will earn
$ 20,448.67 from his investment

This means that Pears are:
= 1 - 2/5
= 3/5
The weight of pears is therefore:
= 3/5 * 7.6
= 4.56 kg
