O No answer text provided.
Answer:
FalseStep-by-step explanation:
It depends on the triangle.
If a is the longest side then it's true, but usually when we talk about Pythagorean theorem we mean that c is the longest side of the right triangle. So:
c² = a² + b²(i will give the brainlyist please help) The solution to the system is (3, 4);

Answer:
1st Picture: d = -16
2nd Picture: g = -13.8
Step-by-step explanation:
1st Picture: Divide both sides by -11 to balance both sides and get the answer.
2nd Picture: Subtract 1.2 from both sides.
Answer:
Question 6:
We have -12.6 = g + 1.2, so we move the 1.2 to the left side to get -13.8 = g because when you move a number you are essentially minusing that number so 1.2 becomes -1.2 .
Question 7:
We have 176 = -11d so we divide by -11 to get -16 = d.

The width of a rectangle measures (8.1g-6.5)(8.1g−6.5) centimeters, and its length measures (4.7g-9.2)(4.7g−9.2) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer:
P = (25.6g - 31.4)
Step-by-step explanation:
Given that,
The width of a rectangle = (8.1g−6.5) cm
The length of a rectangle, = (4.7g−9.2)
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
Substitute all the values,
P = 2(8.1g−6.5+4.7g−9.2)
= 2(12.8g-15.7)
= 25.6g - 31.4
So, the perimeter of the rectangle is equal to (25.6g - 31.4).

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.

Firas and Nabil are comparing their bank accounts. "I have four times more money than
you" , Firas says. "Anyway, I have only $240 less than you" , Nabil answers .
How much money does each one of them have in his account ?
should be solved as a system
Answer:
Firas = $320
Nabil = $80
Step-by-step explanation:
Firas = 4x
Nabil = x
x + 240 = 4x
3x = 240
x = $80
Firas = $240 + $80 OR $80 x 3 = $320
Nabil = $80

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.
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

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

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.
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
help? please and thank you
Answer:
first one
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
What is the value of 19-7-15+14
Answer: the answer is 11 :)
Step-by-step explanation: I hope this helped!
Answer:
11
Step-by-step explanation:
19 - 7 = 12 - 15 = -3 + 14 = 11
or, if your brain likes it better, add the positives, then add the negatives, then subtract:
19 + 14 = 33
-7 -15 = -22
33 - 22 = 11
