Answer:
Evergreen Eagle can will fly 1.56 km in 20 minutes.
Step-by-step explanation:
Speed of Evergreen Eagle = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
= [tex]\frac{13}{1}[/tex]
= 13 meters per second
With this speed Eagle can fly the distance in 20 minutes Or 120 seconds
= Speed × Time
= 13 × 120
= 1560 meters
Since, 1000 meters = 1 Km
1 meter = [tex]\frac{1}{1000}[/tex] km
Therefore, 1560 meters = [tex]\frac{1560}{1000}[/tex]
= 1.56 km
Therefore, Evergreen Eagle can will fly 1.56 km in 20 minutes.
El administrador de una finca tiene suficiente alimentacion para alimentar 220 vacas durante 45 dias. ¿Cuantos dias podra alimentar con la misma cantidad de alimento a 450 vacas? A. 11 B. 44 C. 90 D. 22
Answer:
D. 22
Step-by-step explanation:
Con la información proporcionada sabes que el administrador puede alimentar 220 vacas durante 45 días y puedes deducir que si el número de vacas aumenta el alimento duraría menos días, lo que significa que estas magnitudes son inversamente proporcionales. Por esto, para encontrar la respuesta debes usar una regla de tres inversa:
220 vacas → 45 días
450 vacas → x
x=(220*45)/450
x= 22 días
De acuerdo a esto, la respuesta es que el administrador podrá alimentar a las 450 vacas por 22 días con la misma cantidad de alimento.

Answer:
A = 45 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h( b₁ + b₂)
where h is the height and b₁, b₂ the parallel bases
Here h = 5, b₁ = 10 and b₂ = 8 , then
A = 0.5 × 5 × (10 + 8) = 0.5 × 5 × 18 = 45 cm²
Find the exact angular velocity in radians per hour wind W= 4.1 rpm
Answer:
1545.66 rad/h
Step-by-step explanation:
We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.
We know that,
1 revolution = 2π rad
1 hour = 60 minute
So,
[tex]4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h[/tex]
So, the required angular velocity is 1545.66 rad/h.

Miguel has a garden that has an area of 300 square feet. If the corn in his garden covers 160 square feet, what percent of the garden is corn?
Im not sure of my answer but I got 5.33 and the 3 repeats
Answer:
Im sorry if I'm wrong but I think it's 300+160=460
Answer:
yes your correct but wrong
Step-by-step explanation:
To find the area that's covered in corn you need to first write your fraction.
160/300
After you do that you have to turn it into a decimal.
.53333...
After that you need to turn it into a percent so your final answer will be....
53.333...%
BTW try looking to see if you need to round, normally it tells you to do that

relationship between base and perpendicular is
given by tan angle
tan x=P/h
remember perpendicular is opposite side of taken angle
tan x=13/8
<x=tàn-¹(13/8)=58.39°
for second one
relationship between base and hypotenuse is given by cos angle
cos G=b/h
cos G=24/32
<G=cos-¹(24/32)=41.4 is your answer

somebody please answer only 11. and 13. ANSWER QUICKLY
Answer:
Step-by-step explanation:
y=mx+b where m is the slope and b is the y intercept, value of y when x=0
11.
Since we are given the point (0,4) we already know that b=4
slope is m=(y2-y1)/(x2-x1), using our two points (0,4)(-1,3) we have
m=(3-4)/(-1-0)
m=-1/-1=1 so the line is
y=x+4
12.
Again they gave us point (0,1) so we know b=1, from points (0,1)(4,2) we find
m=(2-1)/(4-0)
m=1/4 so our line is
y=x/4+1 (or more neatly)
y=(x+4)/4
what is n if the equation is
n - 2 divided by -3 = -6

A sports equipment researcher investigated how different types of wood used to make baseball bats might affect batting. The researcher selected a sample of 80 batters from summer baseball leagues and randomly assigned the batters to one of two groups: the ash bat group or the maple bat group. The mean number of hits for each group was recorded at the end of the season, and the difference in the sample means was calculated. Which of the following is the appropriate inference procedure for analyzing the results of the investigation?
A. A one-sample t-interval for a population mean
B. A one-sample t-interval for a sample mean
C. A matched pairs t-interval for a mean difference
D. A two-sample t-interval for a difference between sample means
E. A two-sample t-interval for a difference between population means
Answer:
E
A two-sample t -interval for a difference between population means
Step-by-step explanation:
i just took the test
The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means
Analysis the results of the investigation:Since the researcher selected a sample of 80 batters from summer baseball leagues and batters assigned to one of the two groups. So this means that the researcher is interested to know whether the mean no of hits should be different for two groups and both groups are independent to each other.
Therefore, The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means

How do I solve this?
Answer:
Step-by-step explanation:
In order to find the answer. You first have to find the measure of the whole circle, which is 180.
Then you subtract 180-95 to find y.
180-95=85
So y=85
Then you subtract 180 from 80
180-80=100
So x=100
z=80
So the answer is D.

Answer:-5+x<-1
Step-by-step explanation:
Answer:
H. -5 + x < -1
Step-by-step explanation:
Okay so let's first look at our little graph thing. What is it saying? It's telling us that what ever x is, it is NOT 4 (because the circle is not filled in) and it is less than 4 (because it's all shaded in before 4). Now that we know this, lets look at our possible answers.
F. x - 3 < 7
Now, for all of these possible answers, we can solve them exactly like normal equations (like x - 3 = 7).
x - 3 < 7
[add 3 to both sides to leave the x by itself]
x < 10
Whoa, that's not right! We don't even have 10 on our graph, so F is out of the running.
G. x + 6 [tex]\leq[/tex] 10
Okay, let's work smarter, not harder here. So we can see that there is a greater than or equal to sign there. So even if we solve it and we get 4 as the answer, our graph doesn't include 4. So we can throw this answer out right away.
H. -5 + x < -1
Solve like a normal equation in the first one.
-5 + x < -1
[add 5 to both sides to leave the x by itself]
x < 4
Hey! We got something! So let's read this with words. So whatever x is, it does not include 4, and is less than 4. So now looking back on our first brainstorm of the graph, this is in line with what we want.
So this is the answer! Yay!
Just for fun let's look at the last possible answer.
I. x - 8 > -4
Again, solve like a normal equation.
x - 8 > -4
[add 8 to both sides to leave x by itself]
x > 4
Oh! Another 4! But this time the sign is different. Let's read it again with words. So whatever x is, it does not include 4 (ok, good), and is greater than 4 (oh, not good). Our graph showed us that x is less than 4. So this answer is not the answer.
So again, we keep H. as our correct answer.
