8 x 10^4 is how many times as large as 4 x 10^-5
Answer:
2 x 10^9
Step-by-step explanation:
There 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.
For example 4/2 = 2
We have to determine 8 × 10⁴ is how many times as large as 4 × 10⁻⁵
Apply the division operation to get
⇒ 8 × 10⁴ ÷ 4 × 10⁻⁵
⇒ (8 × 10⁴) / (4 × 10⁻⁵)
Reduce the term of the numerator
⇒ ( 10⁴) / (10⁻⁵)
⇒ ( 10⁴) × (10⁵)
⇒ ( 10⁴⁺⁵)
⇒ 10⁹
Hence, there 8 × 10⁴ would be 10⁹ times as large as 4 × 10⁻⁵ which is determined by the division operation.

Perimeter of rectangle = 26
Length is 7 less than 9 times the width.
We have to find the width of rectangle[tex].[/tex]
_________________________________
Let, width of rectangle be x therefore length of rectangle will be (9x - 7)
We know that, perimeter of rectangle is given by
perimeter = 2 (length + width)⇒ perimeter = 2 (l + b)
⇒ 26 = 2 [(9x - 7) + x]
⇒ 13 = x + 9x - 7
⇒ 20 = 10x
⇒ x = 2 (width)
Cheers!Step-by-step explanation:
Let breadth be x
As it is given that, the Length is 7 less than 9 times :
Therefore, Length will be 9x - 7
Perimeter of reactangle = 26
➳ 2 ( Length + Breadth) = 26
➳ 9x - 7 + x = 26/2
➳ 10x = 13 + 7
➳ 10x = 20
➳ x = 2
Therefore,
Breadth = x = 2 Length = 9x - 7 = 9(2) - 7 = 11I got stuck here on this question... this is Algebra 2 btw

37
I used the formula (32°F − 32) × 5/9 = 0°C (but ofc replaced the numbers with 99)
Yeah and i rounded 98.6 to 99. 99 Fahrenheit is 37.2222... so i rounded it down to 37. So i think the answer is 37.
You pick one card from a standard deck of 52 cards. What is the probability that the card will be a two?
Answer:
4 out of 52 or simplified 2 out of 26
Step-by-step explanation:
There are 4 suites of cards, spades, hearts, clubs, diamonds and there is one card for two in each suite, so we therefore know that the probability of picking a two out of a 52 card deck will be four out of 52 or the simplified answer would be 2 out of 26. Hope this helps, have a great day!
Saritha will construct a rectangle that has a height of 4 units and an area of up to 48 square units. Which inequality represents all the possible lengths in units of the bases, b, that Saritha can use to construct this rectangle?
Given:
Height of rectangle = 4 units
Area of rectangle up to 48 square units.
To find:
The inequality which represents all the possible lengths in units of the bases.
Solution:
Let the possible lengths in units of the bases be b.
Area of rectangle = Length × width
Here, Height of rectangle = width = 4 units. So, area of rectangle is
[tex]Area=b\times 4[/tex]
[tex]Area=4b[/tex]
Area of rectangle up to 48 square units. It means the area should be less than or equal to 48 square units.
[tex]4b\leq 48[/tex]
Divide both sides by 4.
[tex]b\leq \dfrac{48}{4}[/tex]
[tex]b\leq 12[/tex]
Length can not be negative or zero.
[tex]0<b\leq 12[/tex]
Therefore, the required inequality is [tex]0<b\leq 12[/tex].
Answer:
H) b ≤ 12
Step-by-step explanation:
48/4 = 12.
12 is the only one you can divide into 48 equally.
X 48 ÷ 192: Can't do
X 48 ÷ 44: Can't do
X 48 ÷ 52: Can't do
√ 48 ÷ 12 = 4

given f(x)= -4x-10 and f(x)=10. find x
Answer:
x = - 5
Step-by-step explanation:
Given
f(x) = - 4x - 10 and f(x) = 10, the equate right sides, that is
- 4x - 10 = 10 ( add 10 to both sides )
- 4x = 20 ( divide both sides by - 4 )
x = - 5

A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 times Kelly’s. If the total bill is $114.00, how much does each person owe?
Answer:
Kelly owes $16.5
Greg owes $33
Joe owes $64.5
Step-by-step explanation:
Let
Kelly's portion = x
Greg's portion = 2x
Joe's portion = 4x - 1.50
Total bill = $114.00
Total bill = Kelly's portion + Greg's portion + Joe's portion
114 = x + 2x + (4x - 1.50)
114 = 3x + 4x - 1.50
114 = 7x - 1.50
Add 1.50 to both sides
114 + 1.50 = 7x - 1.50 + 1.50
115.5 = 7x
Divide both sides by 7
x = 115.5 / 7
= 16.5
x = $16.5
Kelly's portion = x
x = $16.5
Greg's portion = 2x
= 2 × 16.5
= $33
Joe's portion = 4x - 1.50
= 4(16.5) - 1.50
= 66 - 1.50
= $64.5
Therefore,
Kelly owes $16.5
Greg owes $33
Joe owes $64.5

a cookie recipe calls for 2/3 cup of brown sugar. sarah is making 1/4 of the recipe. how much brown sugar will she need
Answer:
She will need 1/6 of a cup of sugar to make 1/4 of the recipe.
Step-by-step explanation:
Write and solve an equation of ratios. On the left side we have the ratio of the fraction of the recipe and on the right that of the amount of sugar in each case:
1 recipe 2/3 cup
------------- = -------------
1/4 recipe x
Cross multiplying gives us:
1x = (1/4)(2/3), or
x =2/12 or 1/6
She will need 1/6 of a up of sugar to make 1/4 of the recipe.
Consider the function g(x) = -3x - 4 if the domain value is selected from the set {-8, -2, 0, 3}, which of the following is a corresponding range value?
A. 18
B. -10
C. -13
D. -5
Answer:
C. -13
Step-by-step explanation:
Solve for g(x) by replacing x with each domain value in the set. Solving for g(x) will give you these numbers:
{20, 2, -4, -13}
-13 is the only value that appears in the range set and in the multiple choice solutions. Therefore, the answer is C. -13
C. [tex]-13[/tex] is a corresponding range value.
The domain of a function refers to the set of all values for which the function is defined.
The range is the set of all values that function takes for the given values of domain.
Domain is [tex]\boldsymbol{\left \{ -8,-2,0,3 \right \}}[/tex]
[tex]g(x)=-3x-4[/tex]
[tex]g(-8)=-3(-8)-4[/tex]
[tex]=20[/tex]
[tex]g(-2)=-3(-2)-4[/tex]
[tex]=2[/tex]
[tex]g(0)=-3(0)-4[/tex]
[tex]=-4[/tex]
[tex]g(3)=-3(3)-4[/tex]
[tex]=-13[/tex]
Range is [tex]\boldsymbol{\left \{ 20,2,-4,-13 \right \}}[/tex]
So, [tex]\boldsymbol{-13}[/tex] is a corresponding range value.

What is the opposite of 8.4
Answer:
-8.4
Step-by-step explanation:
Because if you want to find the opposite of a number then you find that same number on the other side on the number line for example, -4.5 you would go on the other side and you would get positive 4.5
Answer:
If you're refering to the additive inverse then it's, -8.4
Step-by-step explanation:
To get an additive inverse or more so an opposite, you simply add the negative to the original for 0.
Example: 8.4 + -8.4 = 0

What is a function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
Now the given function is,
h(x) = -x + 1
To find the value of h(0), put x= 0 in the given equation
⇒ h(0) = -0+ 1
Since, -0+ 1= 1
∴We obtain,
h(0) = 1
which the required value of h(0).
Hence,the required value of h(0) is 1.

Find the distance between the points (5, 3) and (7,6).
Answer:
[tex]d = \sqrt{13}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you determine the distance between the two following points:
-Distance Formula:
[tex]d = \sqrt{(x_{2} - x_{1})^2 + ( y_{2} - y_{1})^2}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the two following points onto that equation:
[tex]d = \sqrt{(7 - 5)^2 + (6 - 3)^2}[/tex]
[tex](x_{1}, y_{1}) = (5, 3)[/tex]
[tex](x_{2}, y_{2}) = (7, 6)[/tex]
-Solve the equation:
[tex]d = \sqrt{(7 - 5)^2 + (6 - 3)^2}[/tex]
[tex]d = \sqrt{2^2 + 3^2}[/tex]
[tex]d = \sqrt{4 + 9}[/tex]
[tex]d = \sqrt{13}[/tex]
So therefore, the distance is [tex]\sqrt{13}[/tex].
