Answer:
34.1
Step-by-step explanation:
8 4/5 is not needed. The other two will given you the answer.
Area = 1/2 * b * h
b = 12 2/5 = 12.4
h = 5 1/2 = 5.5
Area = 1/2 * 12.4 * 5.5
Area = 34.1 square feet.

Ann is twice as old as mary and three times as old as donald. Together their ages total 99. How old is ann?
Answer:
54 years
Step-by-step explanation:
Given that :
Let :
Ann's age = x
Mary's age = x/2
Donald's age = x/3
x + x/2 + x/3 = 99
Take the L. C. M
(6x + 3x + 2x) / 6 = 99
11x / 6 = 99
11x = 99 * 6
11x = 594
x = 594 / 11
x = 54
Hence, Ann is 54 years
One of the base angles in an isosceles triangle is 75 degrees, then its exterior angle is
A. 105 degrees
B.75 degrees
C. 285 degrees
D, 30 degrees
Answer:
105 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
You just gotta subtract your given (in your case 75) from 180 to get your answer my guy

Use the Substitution Method, what is the point of intersection for the following system:
2x + 2y = 18
Y = 2 - 3
Answer:
[tex]2x + 2(x - 3) = 18 \\ 2x + 2x - 6 = 18 \\ 4x = 24 \\ x = 24 \div 4 = 6 \\ y = x - 3 = 6 - 3 = 3[/tex]

the diameter is a circle is 16in. Find it’s circumference in terms of π.
C= ________in
According to the question,
Diameter of circle = 16 inWe are asked to calculate it’s circumference in terms of π.
★ Circumference of circle = 2πr
___________________________________
Let us first calculate the radius of the circle.
→ Diameter = 2 × Radius
→ 16 in = 2r
→ r = 16 in ÷ 2
→ r = 8 in
___________________________________
Substituting values in the formula of circumference,
→ C = 2πr
→ C = (2 × π × 8) in
→ C = 16π in
Therefore, 16π inches is the required answer.

The number of high school seniors graduating from a certain high school increases each year. The equation y = 21.8571x + 309.3333 is the least squares regression line for the number of high school seniors, y, graduating from a high school x years since 2010. For each subsequent year, about how many more seniors graduate from the high school? Round to the nearest whole number
Answer:
22
Step-by-step explanation:
The 309.3333 is the base amount of seniors that graduate each year, the x is the number of years, so the 21.8571 is the number of students they increase by. This answer is 100% I took the final and got it right. Hope this helps!! :)

Can you find the
rectangle's perimeter
I’m marking branliest
Answer:
P = 10x+4
Step-by-step explanation:
The perimeter of a rectangle is given by
P = 2(l+w) where l is the length and w is the width
P = 2( 3x+2+ 2x)
Combine like terms
P = 2(5x+2)
Multiply by 2
P = 10x+4

Simplify the ratio-
2kg : 3kg : 1.5 kg
Answer:
1.33kg : 2kg : 1kg
Step-by-step explanation:
2kg : 3kg : 1.5 kg
Given data
We have the ratio
2kg : 3kg : 1.5 kg
Let us reduce the ratio further
2/1.5: 3/1.5 : 1.5/1.5
1.33kg : 2kg : 1kg
Hence the simplified ratio is 1.33kg : 2kg : 1kg
There is just enough water in the container to exactly fill the
hemisphere. The container is held so that the point of the cone
is down and the altitude of the cone is exactly vertical. Find the
height of the water in the cone. Round to the nearest tenth.
Answer: hello your question is Vague hence I will provide a general solution. in which you can input your values into and get your answer.
answer = h = 3 ( V / π r^2 )
Step-by-step explanation:
The volume of a cone is exactly the volume of a hemisphere, given that the radius and height are the same .
The height of the water in the cone = height of the hemisphere / height of cone ( given that the water completely fills the hemisphere )
∴ h = 3 ( V / π r^2 )
A bookstore in the mall is trying to determine how many mall shoppers are interested in purchasing
books as gifts. To obtain a random sample, the manager surveys every third person that enters the
bookstore.
Does the sample represent the population? Why or why not?
Select the option that correctly answers both questions.
O yes, because people who are already searching for books will give the best responses
O yes, because every third person that enters the bookstore is representative of all
shoppers in the mall
O no, because the manager needs to survey every person that enters the bookstore in
order to represent the population
O no, because people in the bookstore are interested in purchasing books, so they do
not represent all shoppers in the mall
Answer:
O no, because people in the bookstore are interested in purchasing books, so they do not represent all shoppers in the mall
Step-by-step explanation:
In the bookstore, the best method which the store keeper wanted to adopt is actually not a sample representation of the population. This is because, since it would be a survey of those that interested in purchasing books as gifts, it should be able to factor in other purchasers in the mall rather than those who purchase from the bookstore only.
Doing this, would help to give an accurate representation of both group in the survey.

Match each expression to its equivalent expression. (6+8)*x 4x+4+2 1 4(2x+3) 6x+8X 1 6(x+y+z) 8x+4+3 1 4(x+2) 6х+бу+6z
If these are separated like:
(6+8)*x, 4x+4+21, 4(2x+3), 6x+8x, 16(x+y+z), 8x+4+31, 4(x+2), and 6x+6y+6z...
Then it will be (6+8)*x with 6x+8x, 4x+4+21 with 8x+4+31, 4(2x+3) with 4(x+2), and 16(x+y+z) with 6x+6y+6z. Due to like terms, it only makes the most amount of sense.

Answer:
[tex]5.8[/tex]
Step-by-step explanation:
Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:
[tex]\frac{31}{43}=\frac{\text{KI}}{8}[/tex]
Solving, we get:
[tex]\text{KI}=\frac{8\cdot 31}{43}\approx \boxed{5.8}[/tex]
