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].
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

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

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.

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.
Answer:
140.6 feet
Step-by-step explanation:
In ΔMNO, the measure of ∠O=90°, the measure of ∠N=62°, and NO = 66 feet. Find the length of MN to the nearest tenth of a foot.
Step 1
We have to find Angle M
Sum of angles in a triangle = 180°
M + N + O = 180°
M = 180° - ( N + O)
M = 180° - ( 90° + 62°)
M = 28°
Step 2
We find the length of MN
We solve using Sine rule
MN/sin O = NO/sin M
MN/sin 90 = 66/sin 28
Cross Multiply
MN = sin 90 × 66/sin 28
MN = 140.58 feet
Approximately = 140.6 feet
18. State the slope and y-intercept of each linear equations.
a. 6(x + y) = 3(x - y)
b. 2(x + y) = 5(y + 1)
c. 5x + 10y - 20 = 0
Answer:
a. The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0
b. The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]
c. The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2
Step-by-step explanation:
The easiest way to find the slope and y-intercept is to put each equation in the slope-intercept form
That is:
y = mx = c
where m is the slope and c is the y-intercept
Part a:
6(x+y) = 3(x-y)
2(x+y) = x-y
2x + 2y = x - y
3y = -x
[tex]y = \frac{-1}{3}x[/tex]
Comparing this with the general formula, we can conclude that:
The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0
Part b:
2(x+y) = 5(y+1)
2x + 2y = 5y + 5
3y = 2x - 5
[tex]y = \frac{2}{3}x - \frac{5}{3}[/tex]
Comparing this with general formula, we can conclude that:
The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]
Part c:
5x + 10y -20 = 0
10y = -5x + 20
[tex]y = \frac{-1}{2} x+2[/tex]
Comparing this with the general formula, we can conclude that:
The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2
Hope this helps :)

The area of a trapezoid is 60 square inches. One of the bases is 8 inches long. The height is 6 inches long. What is the length of the second base?
Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
[tex]\frac{1}{2}[/tex] × 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches

Select ALL sets of numbers that are possible values for x in the inequality, x > -5. { -4 , 2 , 4 } { -6 , -7 , 4 } { 5 , 0 , -4 } { -5 , -12 , -8 }
Answer:
{ -4 , 2 , 4 } and { 5 , 0 , -4 }
Step-by-step explanation:
Given the solution to an inequality expression as x > -5. The values of x are the values that are greater than -5.
The values greater than -5 are the values that falls towards the positive sides of the number line but greater than -5. The numbers are -4, -3, -2, -1, 0 ,1 ,2, 3, 4, 5, 6....
From the given numbers, the correct set of numbers will be { -4 , 2 , 4 } and { 5 , 0 , -4 } since the values are within the range of listed values

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

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...
