Answer:
416.8 pounds.
Step-by-step explanation:
The mean weight of the 28 bears at a zoo is 413 pounds.
The Total Weight of the 28 bears = Mean weight × number of bears
= 413 pounds × 28 bears
= 11564 pounds
Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo.
This means the total number of bears
= 30 bears because two additional bears were added
What is the new mean of the weight of the bears at the zoo?
New Mean = 11564 pounds + 505 pounds + 434 pounds/30 bears
= 12503 pounds /30 bears
= 416.76666667 pounds
Approximately to the nearest tenth = 416.8 pounds.
Use f(x) = 1/2x and f -1(x) = 2x to solve the problems.
f(2) =
f−1(1) =
f−1(f(2)) =
[tex]f(2) = \frac{1}{2} \times 2 = 1\\f^{-1}(1) = 2 \times 1 = 2\\f^{-1}(f(2)) = f^{-1}(1) = 2[/tex]
Note: [tex]f^{-1}(f(x)) = x[/tex] because f -1 and f cancel each other out.
Answer:
f(2) =
⇒ 1
f−1(1) =
⇒ 2
f−1(f(2)) =
⇒ 2
f−1(−2) =
⇒ -4
f(−4) =
⇒ -2
f(f−1(−2)) =
⇒ -2

Evaluate the piecewise defined function at the indicated values.
{x² + 4x if x <equal/greater to -1
f(x) = { x if - 1<x< equal/greater to 1
{-1 x > 1
f(-2)=
f(-3/2)=
f(-1) =
f(0) = 0
f(25) =
Given:
Consider the piecewise function is
[tex]f(x)=\left \{\begin{matrix}x^2+4x,\text{ if } x\leq -1\\ x, \text{ if }-1<x\leq 1\\-1,\text{ if }x>1\end{Matrix}\right.[/tex]
To find:
The value of the function at indicated values.
Solution:
We know that, [tex]-2,-\dfrac{3}{2},-1[/tex] are less than or equal to -1. So, for these values the function is [tex]f(x)=x^2+4x[/tex].
For x=-2,
[tex]f(-2)=(-2)^2+4(-2)[/tex]
[tex]f(-2)=4-8[/tex]
[tex]f(-2)=-4[/tex]
Similarly,
For [tex]x=-\dfrac{3}{2}[/tex].
[tex]f(-\dfrac{3}{2})=(-\dfrac{3}{2})^2+4(-\dfrac{3}{2})=-\dfrac{15}{4}[/tex]
For [tex]x=-1[/tex].
[tex]f(-1)=(-1)^2+4(-1)=-3[/tex]
We know that, 0 is lies between -1 and 1. So, for this values the function is [tex]f(x)=x[/tex].
For x=0,
[tex]f(0)=0[/tex]
We know that, 25 is greater than 1. So, for this values the function is [tex]f(x)=-1[/tex].
For x=25,
[tex]f(25)=-1[/tex]
Therefore, the required values are, [tex]f(-2)=-4, f(-\dfrac{3}{2})=-\dfrac{15}{4},f(-1)=-3,f(0)=0,f(25)=-1[/tex].

Since we know that the 2 lines are parellel, we know that the angles will add up to 180
sooo
180-119=61 (The angle in the traingle)
We know that the angles of a trinalge add up to 180
61+18+e=180
e=101 degrees

Answer:
6. (x,y) -> (x,y-4)
7. (x,y) -> (-x,y)
Step-by-step explanation:
6. You shift it 4 units down. Y makes things go up and down.
7. Youre flipping it over the Y axis. It doesnt change the Y values, only the X.
9−7x=16 its a two step equation
Answer: -1
Step-by-step explanation:
1. Subtract 9 on both sides.
That would make -7x=7
2. Then divide both sides by 7.
You get -1 (7/-7 equals -1).
I really hope this helped:) can you pls make me branliestttt

8n + 8 =-56 its a two step equating help please
Answer:
n = -8
Step-by-step explanation:
Original Equation:
8n + 8 = -56
Subtract 8 from boths sides.
8n = -64
Divide both sides by 8
n = -8
Hope this helped :)
Please consider Brainliest :)
Step-by-step explanation:
its -8
8n + 8 = 56
8n + 8 - 8 = 56 - 8
8=−64
8n/ 8 -= -64
8n / 8 = -64 / 8
simplified = n = - 8
n equals -8

Complete Question
You are measuring walnuts for banana-walnut oatmeal and a spinach and walnut salad. You need 3/4 cup of walnuts for the oatmeal and 7/8 cup of walnuts for the salad. You have a 1/8 -cup scoop. Complete the descriptions of two different ways to find how many scoops of walnuts you will need. Enter all non-whole number answers as mixed numbers in simplest form.
Answer:
13 scoops
Step-by-step explanation:
Description 1
Step 1
3/4 cup of walnuts for the oatmeal
7/8 cup of walnuts for the salad
Total cups of walnuts needed for both salad and oatmeal =
3/4 cups + 7/8 cups
(3/4 + 7/8)
(6 + 7/8)
= 13/8 cups of walnuts
= 1 5/8 cups of walnuts
Step 2
You have a 1/8 -cup scoop
The number of cup scoops of walnuts need is calculated as
1 5/8 cups ÷ 1/8 cup scoop
= 13/8 ÷ 1/8
= 13/8 × 8/1
= 13 scoops
Therefore, 13 scoops of walnuts is needed.
Description 2
3/4 cup of walnuts for the oatmeal
7/8 cup of walnuts for the salad
1/8 cup scoop
Therefore,
(3/4 + 7/8) ÷ 1/8
=(13/8) ÷ 1/8
= 13 scoops of walnuts are needed

Step-by-step explanation:
Kendall measured the temperature outside to be 68°F. She needs to convert the temperature to degrees celsius.
C=5/9(F-32)
[]68°F is 20°C
[]68°F is 5.7°C
Answer:
68°F is 20°C
Step-by-step explanation:
C = (5/9)(F - 32)
C = (5/9)(68 - 32)
C = (5/9)(36)
C = 5 * 4
C = 20
Answer: 68°F is 20°C
Write an equation in slope-intercept form for the line with slope 7 and y-intersept -7
Answer:
y = 7x - 7
Step-by-step explanation:
1st we can look at the meaning of a slope intercept equation
y = mx = b
m = the slope
b = the y-intercept
now when looking at your equation you can plug in your numbers.
y = 7x - 7 is your final answer
High Hopes ^^
