Simplify [tex]\frac{9x^2 - 3x}{6x - 45x^2}[/tex]
There are multiple ways of going about this, but what I find easiest for a problem like this is to find the GCF of all the terms.
The GCF of [tex]9x^2,-3x,6x,-45x^2[/tex] is [tex]3x[/tex].
Meaning that we can take out 3x out of all the terms and still be left with the simplest, yet equivalent for of the expression.

The stock of Company A gained 6.5% today to $40.47. What was the opening price of the stock in the beginning of the day?
Answer:
$37.84
Explanation:
We need to see what to multiply $40.47 by to find the price of the stock from the beginning. First, we need to subtract 100% by the percentage of gain.
100% - 6.5% = 93.5%
Next, we need to divide 93.5% by 100.
93.5% ÷ 100 = 0.935
Lastly, we multiply $40.47 by 0.935 and round it to the nearest hundredth.
40.47 × 0.935 = 37.83945 --> 37.84
Hope this helped!

Find the missing angles with reasons. plz quick it is due today
Answer:
d = 64, e = 64, g = 55, f = 55
Step-by-step explanation:
Answer:
[tex] \boxed{ \bold{ \sf{see \:below}}}[/tex]
Step-by-step explanation:
d = 64° ( Being vertically opposite angles )
e = 64 ° ( Being alternate angles )
2. g + 125 ° = 180 ° ( sum of supplementary angle)
Move 125 to right hand side and change it's sign
g = 180° - 125°
Subtract 125 ° from 180 °
g = 55 °
f = g ( being alternate angles )
f = 55 °
Hope I helped!

Diego needs to put down sod on a yard that measures 30 feet by 45 feet. Company A says it can do the job for $3.90 per roll of sod, where one roll of sod is a rectangle with dimensions of 2 feet by 5 feet Company B says it can do the job for $150.00 per pallet that covers 450 square feet plus a $45 one-time dellvery charge. Which company is a better deal ? How much will Diego save?
Answer:
Company B is the better deal. Diego will save $31.5.
Step-by-step explanation:
First, find the area of the rectangle: 45*30=1350 sq.ft.
Next, find out how much it will cost for Company A: $3.9 for 2 x 5 ft (10 sq.ft)
Divide 1350 by 10 to see how many of their sod rolls will fit into his yard=135.
Multiply $3.9 by 135=526.5$
Do the same with Company B: $150 for 450 sq.ft plus $45 delivery.
Dived 1350 by 450 to see how many rolls= 3
Multiply $150 by 3= $450, then add $45= $495
Subtract Company B's $495 from Company A's $526.5= $31.5 <-how much Diego saved.
Diego will save $31.50 by choosing Company B instead of Company A.
What is Algebra?For business A:
The yard's entire square footage is calculated as,
⇒ 30 x 45
⇒ 1,350 square feet
The total area covered by each roll of sod must then be determined in square feet is calculated as,
⇒ 2 x 5
⇒ 10 square feet per roll
The total quantity of sod rolls required is calculated as,
⇒ 1,350 / 10
⇒ 135
The price of each roll of sod is $3.90, making the total price of the sod calculated as,
⇒ 135 x $3.90
⇒ $526.5
For business B:
The garden is still 1350 square feet in size overall. Pallets have a surface area of 450 square feet each, thus a total of:
⇒ 1,350 / 450
⇒ 3
The price of the sod is $150.00 per pallet, making the total price calculated as,
⇒ 3 x $150
⇒ $450
In addition, there is a $45.00 one-time shipping fee. Therefore, Company B's overall cost is calculated as,
⇒ $450.00 + $45.00
⇒ $495.00
We can see by comparing the two options that Company B is the better value because it is less expensive than Company A. Diego will save:
⇒ $526.50 - $495.00
⇒ $31.50.
Diego will save $31.50 by choosing Company B instead of Company A.

Answer:
because the way she asked it and the way she put in in form
Kareem is incorrect the ratio of 4:1 can never be equal to the ratio of 12:9.
What is a ratio?In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number. The fraction is defined as the division of the whole part into an equal number of parts.
It is given that Kareem says that the ratio 4:1 is equivalent to the ratio 12:9 because 4 + 8 = 12 and 1 + 8 = 9. Calculate the ratio now.
The above statement is wrong the ratio will be calculated as:-
12 / 9 = ( 3 x 4 ) / ( 3 x 3 )
Take 3 commons from the numerator and the denominator of the ratio.

After a translation (x+3, y-2) the coordinates of D' be (4, 0).
What is a trapezoid?An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.
A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.
The altitude is the measurement of the angle perpendicular to the parallel sides.
The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.
From the given figure of this trapezoid in a coordinate plane, the points of D is (1, 2).
Now, If this trapezoid is moved through the translation (x + 3, y - 2) the coordinates of D' will be (1 + 3, 2 - 0) ⇒ (4, 0).

A real estate agent's base salary is 22,000 per year. The agent earns a 4% comission on total sales. How much must the agent sell to earn 60,000 in one year
Answer: 950,000
Step-by-step explanation:
base salary is 22,000
Target 60,000
60,000-22,000 =38,000 which is 4%
So 38,000/4 = 9,500 which is 1%
So 9,500 * 100 = 950,000 which is 100% total sale
So commission of 4% on 950,000 is 38,000
Therefore 38,000 + 22,000 = 60,000

Grissom draws different sized spheres in a notebook. He knows there is a relationship between the volume of the sphere and the length of its diameter. What is the independent quantity in the situation?
Answer:
The independent quantity in the situation is the length of the diameter.
Step-by-step explanation:
Consider a relationship between two variables.
Of the two variables one variable is dependent upon the other.
Dependent variables are those variables that are under study, i.e. they are being observed for any changes when the other variable values are changed.
Independent variables are the variables that are being altered to see a proportionate change in the dependent variable.
In this case, it is provided that Grissom knows there is a relationship between the volume of the sphere and the length of its diameter.
With every sphere that Grissom draws, the volume of the sphere changes according to its diameter length.
That is the volume of the sphere depends upon the length of its diameter.
Thus, the independent quantity in the situation is the length of the diameter.

the prism has a volume up to 150.find the length of the prism
Step-by-step explanation:
We have to know that in order to solve for the volume of a rectangular prism, we have to use this formula: l * w * h. This stands for length multiplied by width multiplied by height.
Step 1
Let's look at the numbers we already have. The height of the prism is 4 feet and the width is 5 feet. When we multiply them together, we got 20 feet.
Step 2
The volume of this prism adds up to 150 square feet. To find the length of this prism, we have to divide 150 by 20.
[tex]150 / 20=7.5[/tex]
Our final answer: l = 7.5 feet
We can check our answer by multiplying all the numbers together.
4 * 5* 7.5 = 150
