The length of a rectangle is four times its width. if the perimeter of the rectangle is 90 cm, find its length and width
Answer:
length 36, width, 9.
Step-by-step explanation:
you are trying to find "X" and it's 4 times the size of y, the whole thing is equal to 90. it would look like this
y=4x
y(4x) + x = 90
5x=90
90/5= 18
the rest is the "y" value, 72.
divide both by 2 because rectangles have 4 sides, and you get the answer above.
How do you do this question?
Part 1
[tex]x = g(y), \ c \le y \le d\\\\\\x = 3+4y^2, \ 1 \le y \le 2\\\\\\\frac{dx}{dy} = 8y, \ 1 \le y \le 2\\\\\\\displaystyle A = 2\pi \int_{c}^{d}y\sqrt{1+[g'(y)]^2}dy\\\\\\\displaystyle A = 2\pi \int_{c}^{d}y\sqrt{1+\left[\frac{dx}{dy}\right]^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}y\sqrt{1+(8y)^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}y\sqrt{1+64y^2}dy\\\\\\\displaystyle A = 2\pi \int_{1}^{2}\sqrt{1+64y^2}*ydy\\\\\\\displaystyle A = 2\pi \int_{65}^{257}\sqrt{u}*\frac{du}{128}\\\\\\[/tex]
In the last two steps I let u = 1+64y^2, so du/dy = 128y which leads to ydy = du/128.
Note the change in the limits of integration. If y = 1, then u = 1+64y^2 = 65. If y = 2, then 1+64y^2 = 257
----------------------------
Part 2
[tex]\displaystyle A = 2\pi \int_{65}^{257}\sqrt{u}*\frac{du}{128}\\\\\\\displaystyle A = 2\pi*\frac{1}{128}\int_{65}^{257}u^{1/2}*du\\\\\\\displaystyle A = \frac{\pi}{64}\int_{65}^{257}u^{1/2}*du\\\\\\\displaystyle A = \frac{\pi}{64}\left(\frac{2}{3}u^{3/2}+C\right)\Bigg]_{65}^{257}\\\\\\\displaystyle A = \frac{\pi}{64}\left(\left(\frac{2}{3}(257)^{3/2}+C\right)-\left(\frac{2}{3}(65)^{3/2}+C\right)\right)\\\\\\\displaystyle A = \frac{\pi}{64}*\frac{2}{3}\left((257)^{3/2}-(65)^{3/2}\right)\\\\\\[/tex]
----------------------------
Part 3
[tex]\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^3}-\sqrt{65^3}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^2*257}-\sqrt{65^2*65}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(\sqrt{257^2}*\sqrt{257}-\sqrt{65^2}*\sqrt{65}\right)\\\\\\\displaystyle A = \frac{\pi}{96}\left(257\sqrt{257}-65\sqrt{65}\right)\\\\\\[/tex]
[tex]\displaystyle A = \frac{\pi}{96}*257\sqrt{257}-\frac{\pi}{96}*65\sqrt{65}\\\\\\\displaystyle A = \frac{257\pi\sqrt{257}}{96}-\frac{65\pi\sqrt{65}}{96}\\\\\\\displaystyle A = \frac{-65\sqrt{65}\pi}{96}+\frac{257\sqrt{257}\pi}{96}\\\\\\[/tex]
In how many ways can you select a committee of four students of a group of nine students?
Answer:
126
Step-by-step explanation:
n! / (r! (n-r)!)
In this case n = 9 and r = 4
9!/ (4! * (9-4)!)
9!/ (4! * 5!)
= 126
9! = 9x8x7x6x5x4x3x2x1
Given x∥y and m∠3=124° . WILL GIVE BRAINLIEST PLEEEASSEEE
What is m∠8?
Enter your answer in the box.
m∠8 =
Answer:
m<8 = 26°
Step-by-step explanation:
Given:
m<3 = 124°
Required:
m<8
SOLUTION:
Find m<4.
m<4 + m<3 = 180° (linear pair)
m<4 + 124° = 180°
m<4 + 124° - 124° = 180 - 124°
m<4 = 26°
Find m<8:
m<8 = m<4 (corresponding angles)
m<8 = 26° (substitution)

angles a and b are complementary angles. If m A = (3x + 9)° and m
ZB = (x - 11)°, then find the measure of angle a
Answer:
78°
Step-by-step explanation:
Since, angles A and B are complementary.
[tex]\therefore m\angle A + m\angle B = 90\degree \\
\therefore (3x+9)\degree + (x - 11)\degree = 90\degree \\
\therefore (3x +x +9-11)\degree = 90\degree \\
\therefore (4x - 2)\degree = 90\degree \\
\therefore 4x - 2 = 90\\
4x = 90+2\\
4x = 92\\ \\ x = \frac{92}{4} \\ \\ x = 23 \\ \\ \because m\angle A = (3x+9)\degree \\ \therefore \: m\angle A = (3 \times 23+9)\degree \\ \therefore \: m\angle A = (69+9)\degree \\ \huge \red{ \boxed{ \therefore \: m\angle A = 78\degree }}[/tex]

PLEASE ANSWER ASAP Michael read 14 books in 26 months. At the same rate, about how many books can he read in 48 months?
Answer:
Well, lets break this down.
If you try to add 26 + 26 it would be 52, which is above 48.
So, we have to find how many books he can read in one month.
All we have to do, is divide!
14 = dividend
26 = divisor
Step 1:
Start by setting it up with the divisor 26 on the left side and the dividend 14 on the right side like this:
26⟌14 Then do the rest, ill wait.
once you have a answer, that is how much he reads a month.
now multiply by 48.

The diagram shows a window in the shape of a square. Each side of the measures 8 √5 centimeters, and the area of the square is 32x square centimeters. What is the value of x?
Answer:
x = 10
Step-by-step explanation:
recall that for a square with side length "L", the area of the square can be expressed as
Area = L x L
or
Area = L²
in this case we are given that Area, A = 32x
and that Side Length, L = 8√5
If we substitute these into the equation, we will get:
Area = L²
32x = (8√5)² (using the properticals of exponents, we can re-write the right side)
32x = (8)² · (√5)²
32x = 64 · 5
32x = 320 (divide both sides by 32)
x = 320 / 32
x = 10
Based on the regression output, which of the following is the predicted time, in minutes, that it took to gather the items if the order has 22 items?
Answer:
The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
Step-by-step explanation:
Regression Output :
Predictor Coefficient
Constant 3.0979
Square root of items 2.7633
R.sq.- 96.7%
So, with this data the regression equation is,
[tex]\hat{y}=3.0979+2.7633x[/tex]
Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items
Substitute x =22 in equation
[tex]\hat{y}=3.0979+2.7633(22)[/tex]
[tex]\hat{y}=63.8905[/tex]
Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
