Answer:
3/10 quarts.
Step-by-step explanation:
Set the denominators equal to one another.
4/5 = 8/10 (multiplied by a factor of 2)
1/2 = 5/10 (multiplied by a factor of 5)
Subtract the 5/10 from the 8/10
3/10 qt

Answer:
Step-by-step explanation: She has 2 more nickels then dimes not 2 times more therefore answers B and D are incorrect. C is incorrect because it has that there are 2 more dimes than nickels. A is correct because it says that there are c dimes, and then c +2 nickels.

solve y/2 + 22 =38 for y
Answer:
y = 32
Step-by-step explanation:
[tex]\frac{y}{2}+22=38\\\frac{y}{2}=16\\y=32[/tex]
Answer:
y=32
Step-by-step explanation:
y/2 + 22 =38
Subtract 22 from each side
y/2 + 22-22 =38-22
y/2 = 16
Multiply each side by 2
y/2 *2 =16*2
y = 32

The formula for the area of a parallelogram is A = bh, where b is the base and h is the height.
A parallelogram that is not drawn to scale. The height is labeled (x minus 4) centimeters. The base is labeled (2 x squared + 2 x minus 6) centimeters.
Which simplified expression represents the area of the parallelogram?
Answer:
Area = 2x^3 - 6x^2 - 14x + 24
Step-by-step explanation:
h = x - 4
b = 2x^2 + 2x - 6
Area = b * h
Area = (x - 4)(2x^2 + 2x - 6) Multiply through by x
Area = 2x^3 + 2x^2 - 6x - 8x^2 - 8x + 24 Multiply through by -4
Area = 2x^3 + (2x^2 - 8x^2) - 6x - 8x + 24 Collect like terms.
Answer
Area = 2x^3 - 6x^2 - 14x + 24

This is a rhombus. Solve for x, Then label each angle with its correct measures:
Answer:
Step-by-step explanation:
In the given rhombus, the value of x is 18.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We know that;
Diagonal bisect the angles of a rhombus.
Hence, We can formulate;
⇒ (2x + 16)° = (3x - 2)°
Solve for x as;
⇒ 2x + 16 = 3x - 2
Subtract 2x both side,
⇒ 2x + 16 - 2x = 3x - 2 - 2x
⇒ 16 = x - 2
Add 2 both side,
⇒ 16 + 2 = x - 2 + 2
⇒ 18 = x
⇒ x = 18
Thus, The value of x in rhombus = 18

Someone pls help…. We need to find m angle f
Answer:
m<F = 95°
Step-by-step explanation:
We'll begin by calculating the value of x. This can be obtained as follow:
m<C = 50
m<A = (10x – 5)
m<B = m<G = (2x + 15)
m<C + m<A + m<B = 180 (Sum of angles in a triangle)
50 + (10x – 5) + (2x + 15) = 180
50 + 10x – 5 + 2x + 15 = 180
50 – 5 + 15 + 10x + 2x = 180
60 + 12x = 180
Collect like terms
12x = 180 – 60
12x = 120
Divide both side by 12
x = 120 / 12
x = 10
Finally, we shall determine the value of m<F. This can be obtained as follow:
m<F = m<A
But
m<A = 10x – 5
x = 10
Therefore,
m<F = 10x – 5
m<F = 10(10) – 5
m<F = 100 – 5
m<F = 95°
According to a government study, among adults in the 25- to 34-year age group, the mean amount spent per year on reading and entertainment is $2,020. Assume that the distribution of the amounts spent follows the normal distribution with a standard deviation of $456. Use Appendix B.3. (Round your z-score computation to 2 decimal places and final answers to 2 decimal places.) What percent of the adults spend more than $2,600 per year on reading and entertainment
Answer:
z = x-u/s
z = 2600 - 2020/456
z = 1.27
= .897
1-.898 = .102
z > 1.27 = 10.2%
The percentage of adults spending more than $2,600 per year on reading and entertainment is 10.2%.
What is the z-score?The standard score in statistics is the number of standard deviations that a raw score deviates from or exceeds the mean of the phenomenon being observed or assessed. Standard scores are positive for raw scores above the mean and negative for raw scores below the mean.
Given that according to a government study, among adults in the 25- to 34-year age group, the mean amount spent per year on reading and entertainment is $2,020. Assume that the distribution of the amounts spent follows the normal distribution with a standard deviation of $456.
The percentage will be calculated as,
z = x-u/s
z = 2600 - (2020/456)
z = 1.27
The value of z=1.27 in the table is 0.897. The percentage will be calculated as,
P = 1-.898 = .102
z > 1.27 = 10.2%
Therefore, the percentage of adults spending more than $2,600 per year on reading and entertainment is 10.2%.

Answer:
Total cost = $6.61
Step-by-step explanation:
Given the following data;
Cost of breaded chicken = $5.68/lb
Quantity of breaded chicken = ¼
Baked chicken = $6.92/lb
Quantity of baked chicken = ¾
To find the total cost;
First of all, we would determine the cost of breaded chicken and baked chicken.
Cost of breaded chicken = ¼ * 5.68
Cost of breaded chicken = $1.42
Cost of baked chicken = ¾ * 6.92
Cost of baked chicken = 20.76/4
Cost of baked chicken = $5.19
Total cost = Cost of breaded chicken + Cost of baked chicken
Total cost = 1.42 + 5.19
Total cost = $6.61

A. The value of expression B is 3 times the value of expression A.
B. The value of expression A is 3 times the value of expression B.
C. The value of expression A 3 times more the value of expression B.
D. The value of expression B is 3 times more than the value of expression A.
Answer:
Both B and C should be correct
Step-by-step explanation:
I'm assuming the x in Expression A is a multiplication symbol. If it is not, please tell me and I will change my answer.
Expression B has the value of 8+4 or 12.
Expression A is 3 times (8+4). You could also say that Expression A is 3 times Expression B.
Since both answer B and C say this, they should both be correct.

When a triangle is inscribed in a semicircle where a diameter of the circle is a side of the triangle, the triangle formed is always a right triangle. If an isosceles triangle (two equal sides) is inscribed in a semicircle with a radius of 9 inches, find the length of the two legs of the triangle.
Answer:
Step-by-step explanation:
diameter = 18 inches
each leg = 18/√2 = 9√2 ≅ 12.7 inches
The length of the two legs of the isosceles triangle is 9√2.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
When a triangle is inscribed in a semicircle with one side being the diameter of the circle, a right triangle is always created.
Also, the radius of semicircle is 9 inches,
Since, the isosceles triangle inscribed in the semicircle.
Sides of an isosceles triangle are equal, therefore the corresponding angle will also equal.
The sum of all three angles of a triangle is 180°
x+x+90 = 180
2x = 90
x=45
radius of circle is 9 inches, therefore diameter of circle = 18 inches
Apply sin rule,
18/sin90 = x/sin45
18/1 = x/1/√2
x= 9√2
The length of the side of the isosceles triangle is 9√2.
