6 X 10^-5 is 2*10^3 times the value of 3 X 10^-8.
6 X 10^-5 is how many times the value of 3 X 10^-8 is to be determined.
Fraction is defined as the number of compositions that constitute the whole.
Let 6 X 10^-5 is x times the value of 3 X 10^-8.
[tex]6 * 10^{-5}= x 3 * 10^{-8}\\\\x = \frac{6 * 10^{-5}}{3 * 10^{-8}} \\\\x = 2 *10^3[/tex]

-2 1/4 = 2w
Answer:
[tex]w=-9/8[/tex]
Step-by-step explanation:
We are given the equation [tex]-2 \frac{1}{4} = 2w[/tex]. To solve this equation, we can divide both sides by 2 to get that [tex]w = -2\frac{1}{4} \div 2 = -\frac{9}{8}[/tex].
Answer:
w = - [tex]\frac{9}{8}[/tex]
Step-by-step explanation:
Given
- 2 [tex]\frac{1}{4}[/tex] = 2w ( change the mixed number to an improper fraction )
- [tex]\frac{9}{4}[/tex] = 2w ( multiply both sides by 4 to clear the fraction )
- 9 = 8w ( divide both sides by 8 )

The measurement of the “ridge” of your new house on blueprints is 24 inches. If the scale is 1/4 = 1ft how long is the wall in real life
Answer:
In real the wall will be: 96 ft
Step-by-step explanation:
Given that the scale is
1/4 = 1ftIt means 1 inch will represent 4 ft.
so
1 inch = 4ft
Given that the measurement of the “ridge” of your new house on blueprints is 24 inches.
Thus,
24 inches = 24 × 4ft ∵ 1 inch = 4ft
= 96 ft
Therefore, in real the wall will be: 96 ft

Determine the percentage change and state whether it's an increase or decrease
Percentage change is calculated as:
[tex]\%Change = \frac{New - Original}{Original} * 100\%[/tex]
[tex]1.\ Original = 5; New = 1.3[/tex]
[tex]\%Change = \frac{1.3 - 5}{1.3} * 100\%[/tex]
[tex]\%Change = \frac{-3.7}5} * 100\%[/tex]
[tex]\%Change = \frac{-3.7 * 100\%}{5}[/tex]
[tex]\%Change = \frac{-370\%}{5}[/tex]
[tex]\%Change = -74\%[/tex]
The percentage change is 74% and it is a percentage decrease
[tex]2.\ Original = 160; New = 136[/tex]
[tex]\%Change = \frac{136 - 160}{160} * 100\%[/tex]
[tex]\%Change = \frac{-24}{160} * 100\%[/tex]

The percentage change is 15% and it is a percentage decrease
[tex]3.\ Original = 15; New = 12[/tex]
[tex]\%Change = \frac{12- 15}{15} * 100\%[/tex]
[tex]\%Change = \frac{-3}{15} * 100\%[/tex]
[tex]\%Change = \frac{-3* 100\%}{15}[/tex]
[tex]\%Change = \frac{-300\%}{15}[/tex]
[tex]\%Change = -20\%[/tex]
The percentage change is 20% and it is a percentage decrease
[tex]4.\ Original = 7; New = 10[/tex]
[tex]\%Change = \frac{10- 7}{7} * 100\%[/tex]
[tex]\%Change = \frac{3}{7} * 100\%[/tex]
[tex]\%Change = \frac{3* 100\%}{7}[/tex]
[tex]\%Change = \frac{300\%}{7}[/tex]
[tex]\%Change = 43\%[/tex] -- (approximated)
The percentage change is 43% and it is a percentage increase
[tex]5.\ Original = $30; New = $18[/tex]
[tex]\%Change = \frac{18- 30}{30} * 100\%[/tex]

If you don't explain u won't get brainliest.
Answer:
Answer is 9
Step-by-step explanation:
Remember PEMDAS???
"parenthesis, exponents, multiplication, division, addition, subtraction"
you would first solve the addition inside of the parentheses (1 + 2 = 3), and from there finish the equation as it's written from left to right.
Answer:
9
Step-by-step explanation:
First, we have to solve inside the parentheses because of PEMDAS or GEMDAS, whichever you know. When we add 1+2 we get 3 inside the parentheses and it looks like this: 6/2(3).
Then, we have to divide 6 by 2 before we do anything else. When we divide 6/2, we get 3 and it will look like this: 3(3).
Finally, we have to multiply 3 by 3 because when something is in parentheses, you have to multiply it by the number right before it (next to it). Once we multiply 3*3, we will get our answer of 9.

35; 30.3
b.
30.3; 28
d.
30.3; 35
Please select the best answer from the choices provided
sorry about the answer choices being mixed up im still in a hurry
Answer:
I'm so sorry I don't know this answer but good luck
Answer: since it doesn't tell you how you get it.
Since the mode of the ages is 35 we know that at least two of the ages are 35. Since the range is 14 we know the third sister is not also age 35. Let x be the age of the third sister. Then we know either 35 - x = 14 or x-35 = 14 (depending if x is younger or older, respectively). Solving both of these gives x = 21 or x = 49. But all the sisters are under the age of 45, so x = 21. Hence, the ages of the sisters are
21, 35, 35.
So, the mean is (35+35+21)/3 = 91/3 =~ 30.3333 ...
The median is 35.

Given the quadratic equation ax2 + 10x + 2 = 0, determine all values of a that will result in this equation having non-real solutions. Show all work that leads to your answer.
Answer:
a>12.5.
Step-by-step explanation:
you need to look at the discriminant in the quadratic formula:
[tex]b^{2} -4ac[/tex]
coming from the quadratic polynomial
[tex]ax^{2} +bx+c=0[/tex]
In our case, b=10 and c=2, hence, the discriminant is
[tex]10^2-4*a*2 \\100-8a[/tex]
We will obtain non-real values if the discriminant is less than zero.
Therefore, this condition is written as
[tex]100-8a<0[/tex]
and we must solve for a. It yields
[tex]100<8a\\a>\frac{100}{8} \\a>12.5[/tex]
Hence, the answer is a>12.5.
The values of a that will result in this equation having non-real solutions must e greater than 12.5
Given the quadratic equation ax^2 + 10x + 2 = 0
For the equation to have non-real solutions, then b^2 - 4ac < 0
From the given equation;
a = a
b = 10
c = 2
Substitute the given parameters into the formula;
10^2 - 4a(2) < 0
100 - 8a < 0
-8a < -100
8a > 100
a > 12.5
Hence the values of a that will result in this equation having non-real solutions must e greater than 12.5

Step-by-step explanation:
Given that:
Larger square is a dilation of smaller square
Dimension of smaller square (5 - 3) units by (5 - 3) units = 2 by 2
Dimension of larger square (7 - 1) units by (7 - 1) units = 6 by 6
Hence, the scale factor used to create the larger square from the smaller square will be:
Scale factor (x) * side of smaller square = side of larger square
x * 2 = 6
2x = 6
x = 6/2
x = 3
Hence, scale factor used to generate larger square is 3

Triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″. If vertex P is at (3, -4) and vertex Q is at (5, -1), what are the coordinates of vertices P″ and Q″?
Answer:
Answer: The correct option is (D) P″(9, -12) and Q″(15, -3).
Step-by-step explanation: Given that triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″.
The co-ordinates of vertices P and Q are (3, -4) and (5, -1) respectively.
We are to find the co-ordinates of the vertices P″ and Q″.
Case I : ΔPQR dilated to ΔP'Q'R'
The co-ordinates of P' and Q' are given by
Case II : ΔP'Q'R' dilated to ΔP''Q''R''
The co-ordinates of P'' and Q'' are given by

The length of a rectangle is 9cm more than four times the width. If the perimeter of the rectangle is 78 cm, what are its dimensions
Answer:
Length is 32. 6 cm and width is 5.9 cm
Step-by-step explanation:
width(w)=w
perimeter(p)=78 cm
length(L) = 4w+9
p=2L+2w
78=2(4w+9)+2w
78=8w + 19 + 2w
10w=59
w=5.9 cm
L=4w+9
L=4(5.9)+9
L=32.6 cm
Therefore length is 32.6 cm and width is 5.9 cm
