Answer:
5
Step-by-step explanation:
you have to subtract 26 on both sides.
so then the equation turns into 7t = 35
then you dive both sides by 7, leaving the equation as t=5

3. Power line
No, the US and other countries shouldn't use more wind energy because the turbine could cause harm to animals that fly.
OR you can say:
Yes, the US and other countries should use more wind energy because it doesn't cause pollution, so no greenhouse gases are made to contribute to global warming.
You can choose either answer. I hope this helps you! ^-^
Which equation of a line passes through the points (-5,2) and (0,7)?
Answer:
I think the answer will be Y=X+7
Answer:
y=x+7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-2)/(0-(-5))
m=5/(0+5)
m=5/5
m=1
y-y1=m(x-x1)
y-2=1(x-(-5))
y-2=x+5
y=x+5+2
y=x+7
The perimeter of the square is 64 inches. What is the perimeter of the shaded region?
Answer:
54.94 inches
Step-by-step explanation:
First you need to find the radius of the semi-circles within the square.
You find this by dividing the perimeter by 8
64/8 = 8
now use the formula πr^2 to find the area of the semi circle
π8^2 = 201.06
Now find the total area of the square and subtract it from the area of the two semi circles to find the shaded region
16*16 = 256
256-201.06 = 54.94
5m - 2n=4
m - 4n = -1
20 3x + 5y = 11
2x - y=3
Answer:
Step-by-step explanation:
5m - 2n = 4
m - 4n = -1 add 4n to both sides m - 4n + 4n = 4n - 1
m = 4n - 1 now substitute for m into the first equation
5(4n -1) - 2n = 4
20n - 5 - 2n = 4 combine the n coeffients and add 5 to both sides
18n - 5 = 4 + 5
18n = 9 solve for n by dividing 18 by both sides
18 n/18 = 9 /18
n = 1/2 now find for m using m = 4n - 1 m = 4(1/2) - 1 m = 2 -1 = 1
m = 1 (1, 1/2) solves the two equations
3x + 5y = 11 equation 1
2x - y = 3 multiply both sides by 5 so when you add the two equation
the y term is eliminated (becomes zero)
5(2x-y) = 5(3)
10x - 5y = 15 equation 2 add equation 1 and equation 2
3x + 5y = 11 add the like terms
10x - 5y = 15 add the like terms
(3x + 10x) + (5y - 5y) = (11 + 15)
13x + 0 = 26 the y tern is gone now solve for x
13x = 26
13x/13 = 26/13
x = 2 now find y using 2x - y = 3
2x - y = 3 add y and subtract 3 from both sides
2x - y + (y - 3) = 3 + (y - 3)
2x - 3 = y we already know x = 2
2(2) - 3 = y
4 - 3 = y
1 = y answer (2,1) solves the two equaitons
In an office, there are 75 women and 125 men .Find the ratio of
the number of men to the number of women.
Given:
In an office, there are 75 women and 125 men.
To find:
The ratio of the number of men to the number of women.
Solution:
We have,
Number of men = 125
Number of women = 75
The ratio of the number of men to the number of women is:
[tex]\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}[/tex]
[tex]\text{Required Ratio}=\dfrac{125}{75}[/tex]
[tex]\text{Required Ratio}=\dfrac{5}{3}[/tex]
[tex]\text{Required Ratio}=5:3[/tex]
Therefore, the ratio of the number of men to the number of women is 5:3.

Express the following in the form 10where n is an integer 10−8 × 10−6
Given:
The given expression is:
[tex]10^{-8}\times 10^{-6}[/tex]
To find:
The expression in the form of [tex]10^{-n}[/tex].
Solution:
We have,
[tex]10^{-8}\times 10^{-6}[/tex]
It can be written as
[tex]10^{-8}\times 10^{-6}=10^{-8+(-6)}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]10^{-8}\times 10^{-6}=10^{-8-6}[/tex]
[tex]10^{-8}\times 10^{-6}=10^{-14}[/tex]
Therefore, the required value is [tex]10^{-14}[/tex].

9x2 - 52x + 33 = -10x - 16
Quadratic Equation
Answer:
x=7/3 or x=2.33
Step-by-step explanation:
9x^2 - 52x + 33 = -10x - 16
Okay, lets Start by converting this into standard form, which is: ax^2 + bx + c = 0.
Add 10x+16 on both sides of the equation, and simplifying.
9x^2 - 52x + 33 + 10x + 16 = -10x - 16 + 10x + 16
9x^2 - 42x + 49 = 0
Guess What! This equation is a Perfect Square Trinomial.
For a Perfect Square Trinomial, you will be able to take the square root of the first and third terms, and the coefficient of the second term will be twice the square root of the third term. The “sign” of your second term in your answer will be the same as the linear term sign.
So this is (3x*3x) + (3x * -7 * 2) + (7 * 7) = 0
So, we can rewrite this as (3x - 7)^2=0
Now, To solve, We can set each factor equal to 0, and solve.
*Since we have a Perfect Square Trinomial, You will get one solution, or value, for x.*
Add 7 on both sides.
3x - 7 = 0
+7 +7
----------------
3x=7
Divide by 3 on both sides.
3x/3 = 7/3
x=7/3
As a decimal: 2.33...

A rectangular piece of land measures 250 m by 220 m. Each side is to be fenced with 3 rows of wires. What is the length of the wire needed?
Answer:
2,820 m
Step-by-step explanation:
Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.
The perimeter p of a rectangle of length l and width b is given as
p = 2(l + b)
Hence p = 2( 250 + 220)
= 2 * 470
= 940 m
Since each side is to be fenced with 3 rows of wires, the length of wire required
= 3 * 940m
= 2,820 m
Find the missing length of the triangle. If necessary, round your answer to the nearest tenth
Answer:
30
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem to find the missing side
a^2 +b^2 = c^2 where a and b are the sides and c is the hypotenuse
x^2 + 40^2 = 50^2
x^2 +1600 = 2500
x^2 = 2500-1600
x^2 = 900
Take the square root of each side
sqrt(x^2) = sqrt(900)
x = 30
Answer:
x = 30
Step-by-step explanation:
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 50^{2} - 40^{2}[/tex]
[tex]a^{2} = 2500 - 1600[/tex]
[tex]a^{2} = 900[/tex]
[tex]\sqrt{a^{2}} = \sqrt{900}[/tex]
a = 30

Which of these equations has no solution? OA) m = 0 OB) m = m = O c) 2m + 1 = m - 2 od m + 4 = m-4
Answer:
OD is the correct answer
Answer:
OD ) m + 4 = m - 4
Step-by-step explanation:
m + 4 = m - 4
m = m - 4 - 4
m = m -8
m -m = - 8
0 ≠ 8
So, this has no solution

Answer:
major arc CEB = 320°
Step-by-step explanation:
arc BF = 140°
arc CE = 140°
