Answer:
he base length of triangle = 16 yd
Explanation:
he base length of triangle = 16 yd
Step-by-step explanation:
Formula:-
Area of triangle
area A = bh/2
b - base of triangle
h - height of triangle
To find the area of triangle
It is given that,A triangle has an area of 80 yd^2 and a height of 10 yd.
here, b = ?, A = 80 yd^2 and h = 10 yd
A = bh/2
80 = (b*10)/2
5b = 80
b = 80/5 = 16
Therefore the base length of triangle = 16 yd
Solve this system of linear equations: 4x-2y=8 Y=3/2x-2
The solution to the system of equations is x = 4 and Y = 4.
Explanation:To solve the system of linear equations, we can use substitution. Since we have the equation Y = 3/2x - 2, we can substitute this expression for Y in the first equation.
Substituting Y = 3/2x - 2 in 4x - 2y = 8:
4x - 2(3/2x - 2) = 8
Simplifying the expression:
4x - 3x + 4 = 8
x + 4 = 8
Solving for x:
x = 8 - 4
x = 4
Substituting the value of x into Y = 3/2x - 2:
Y = 3/2(4) - 2
Y = 6 - 2
Y = 4
Therefore, the solution to the system of equations is x = 4 and Y = 4.

a group of rangers work 5 days per week. it takes them 4 days to plant trees on 1/2 acre.what is the unit rate per week
The unit rate at which the group of rangers plants trees is 5/8 of an acre per week, which is found by calculating the daily acreage planted and then multiplying by the number of workdays in a week.
Explanation:To determine the unit rate per week of the group of rangers planting trees, we need to calculate how much of an acre they can plant in a standard work week. As it takes them 4 days to plant trees on 1/2 acre, they will plant 1/2 acre in every 4 days of work. Since they work 5 days per week, we can adjust the ratio to calculate the weekly rate:
1/2 acre in 4 days is equivalent to (1/2 acre)/(4 days).Now, find out how much is planted in 1 day: (1/2 acre)/(4 days) = 1/8 acre in 1 day.Finally, multiply by 5 to get the weekly amount: (1/8 acre) * 5 days = 5/8 acre per week.Therefore, the unit rate at which the group of rangers plants trees is 5/8 of an acre per week.

Each of the letters of the word ALABAMA are written on a piece of paper and then put into a bag. A piece of paper is drawn at random. What is the theoretical probability, as a decimal, of drawing an A? Round the decimal to the nearest hundredth.
The theoretical probability of drawing an 'A' from the word 'ALABAMA' is 0.57. This result arrives from dividing the number of 'A's (4) by the total number of letters in 'ALABAMA' (7).
Explanation:The question deals with a probability problem related to the selection of letters from the word 'ALABAMA'. The word 'ALABAMA' has 7 letters out of which 4 are 'A's. The theoretical probability is calculated as the number of successful outcomes divided by the total number of outcomes. Since we are interested in drawing an 'A', the successful outcomes are the number of 'A's which is 4, and the total outcomes are the total number of letters which is 7.
To calculate theoretical probability, you divide the number of successful outcomes by the total number of outcomes. In this case, the calculation will be 4 / 7 = 0.57 (rounded to the nearest hundredth).
So, the theoretical probability of drawing an A from the word 'ALABAMA' in decimal form, rounded to the nearest hundredth, is 0.57.

Prove algebraically what type of function this is (even, odd, or neither).
The given function is even.

Pamelas age is. 2 times jiris age. The sum of their ages is 30.what is jiris age?
Answer:
Pamela is 20 years old
Jiris is 10 years old.
Step-by-step explanation:
The very first step is to identify your variables. Let's say that Pamela is 'P' and lets say Jiris is 'J.' The next step is to create an equation. 'The sum of their ages is 30' is something that we can use. So, P + J = 30. The next step is to see that Pamela is two times Jiris' age. So we can say that P = 2J. Now, in order to solve for one variable, we need to do some substitution. We know that P = 2J, so we can plug that into the first equation (P + J = 30). With this change, we now have, 2J + J = 30. With that, you combine like terms and solve for J to get an answer of J = 10. Now we can use that number and plug it into one of our previous equations, like P + J = 30. Now it is going to be P + 10 = 30. Solve for P and get an answer of 20 years old.

Area of the larger circle is 9/4 πx²
Step-by-step explanation:
Step 1: Given area of the small rug = 1/4 πx² Compare this to the formula for area of a circle.⇒ 1/4 πx² = πr²
⇒ x²/4 = r²
∴ r = x/2
Step 2: Given radius of the larger circle is 3 times that of the smaller circle (r = 3x/2), find area of the larger circle.Area of the larger circle = πr² = π × (3x/2)²
= 9/4 πx²
What is the volume, in cubic m, of a cube with an edge length of 11m?
the volume of cube with edge length 11 m is [tex]Volume = 1331m^3[/tex] .
Step-by-step explanation:
Here we have a side length of a cube as 11 m . We need to find the volume of cube . Let's find out:
We know that every side of a cube is identical and equal . And volume of cube is given by formula :
⇒ [tex]Volume = (side)^3[/tex] ...........(1)
According to question we have following parameters as
[tex]side = 11m[/tex]
Putting this in (1)
⇒ [tex]Volume = (11m)^3[/tex]
⇒ [tex]Volume = 11(11)(11)m^3[/tex]
⇒ [tex]Volume = (121)(11)m^3[/tex]
⇒ [tex]Volume = 1331m^3[/tex]
Therefore , the volume of cube with edge length 11 m is [tex]Volume = 1331m^3[/tex] .
The volume of the cube is 1331 m³
Explanation:
Given:
side of the cube, a = 11m
Volume of the cube, v = ?
we know:
Volume of the cube = (a)³
V = (11m)³
V = 1331 m³
Therefore, the volume of the cube is 1331 m³
A group of middle school boys have a mean height of 167 cm and a range of 164 cm to 169 cm. A group of high school boys have a mean height of 180 cm and a range of 175 cm to 183 cm. Which statement BEST compares the two groups of boys?
Answer:
C
Step-by-step explanation:
The high school boys vary in height more than the middle school boys.
middle school boys range = 169 − 164 = 5 cm
high school boys range = 183 − 175 = 8 cm
The range for both conditions is 5 cm and 8 cm respectively.
What is the range?The difference between the highest and lowest value data points of the provided data is known as the range in mathematics.
In statistics, the mean is the product of all the values in a set of data divided by the total number of values in the data for a given set of observations.
The high school boys vary in height more than the middle school boys.

N x 23 = 8.05 solve for N
Answer:
0.35
Step-by-step explanation:
Just divide 8.05 by 23
The answer you are looking for is 0.35.
To solve for any variable (N in this case) you must get it by itself, by doing the opposite operation. To do so for this problem, divide 23 from both sides. In doing so, N will be by itself, and you'd then just divide 23 from 8.05. Thus getting 0.35 as an answer.

let f(7)=12 and g(2)=7 what is the value of (f•g)(2)
Final answer:
The value of (f•g)(2), given f(7)=12 and g(2)=7, is 12. This is found by first applying g to 2 to get 7, and then applying f to get f(7), which equals 12.
Explanation:
The question pertains to the composition of functions and the use of the chain rule in calculus. Given that f(7)=12 and g(2)=7, we need to find the value of (f•g)(2). The notation (f•g)(x) means we first apply g to x, and then apply f to the result of g(x). Therefore, to find (f•g)(2), we first find g(2), which is 7, and then find f(g(2)) which is f(7). Since we know that f(7)=12, the value of (f•g)(2) is therefore 12.
