Step-by-step explanation:
Let x be the money made in sales. Let y be the money made in commissions.
First, convert 2.5% to a decimal.
2.5% = 0.025
Equation:
0.025x = y
Robert:
0.025(8850) = y
y = $221.25
Francisca:
0.025x = 279
x = 279/0.025
x = $11,160
if f(x)= x^2 and g(x) = 4f (x)-1 then which of the following is the value of g (-3)
view image below to see answer choices
Answer:
27Step-by-step explanation:
Given
f(x)= x^2-2 and g(x) = 4f (x)-1
g(x) = 4(x^2-2) - 1
g(x) = 4x²-8-1
g(x) = 4x²-9
Get g(-3):
g(-3) = 4(-3)²-9
g(-3 = 4(9) - 9
g(-3) = 36-9
g(-3) = 27

if x²+y²=6xy then prove that 2log(x+y)=logx+logy+3log2
Answer:
Given that
x² + y² = 6xy
or, (x + y)² - 2xy = 6xy
or, (x + y)² = 8xy
or, (x + y)² = 2³xy
Taking (log) in both sides, we get
log (x + y)² = log (2³xy)
or, 2 log (x + y) = log (2³) + logx + logy
or, 2 log (x + y) = 3 log2 + logx + logy

Keith and his 6 friends are taking a trip. The total cost of the trip is $1,145.55. The total cost of the tickets for the amusement park was $341.25. The total cost of three hotel rooms was $454.65. The total cost for the show they were going to see was $153.65. The rest of the money they paid was used to purchase gas for their trip. Use this information to answer the questions below.
Answer and explanation:
Question is incomplete
Question will likely ask how much is the rest of the money paid for gas.
We use algebra to find how much is the rest of the money paid for gas
So given
total cost of the trip = $1,145.55
total cost of tickets for amusement park = $341.25
The total cost of three hotel rooms = $454.65
total cost for the show they were going to see = $153.65
Let's call rest of money spent on gas x
Hence the equation for total cost with all expenditures,
$341.25+$454.65+$153.65+x=$1,145.55
Solve for x
$949.55+x=$1145.55
x=$1145.55-$949.55
x= $196
Therefore amount spent on gas for the trip =$196

Describe how to create an equivalent equation from an equation that has fractions or decimals. Explain how to decide what numbers to use to multiply. Also, explain any other important things to remember when using this process.
Answer:
i hope this helps :)
Step-by-step explanation:
So, with an equation with decimals, we can use the same method we used to clear fractions—multiply both sides of the equation by the least common denominator. Look at the decimals and think of the equivalent fractions. Notice, the LCD is 100. By multiplying by the LCD, we will clear the decimals from the equation.
Answer: If the equation have fractions in it, then find the LCM of all the denominators.Then multiply both side of the equation by that LCM.
If the equation has decimal, then count the maximum number of places after decimal. Then multiply by "1 and then that many zeros".
Steps: If the equation have fractions in it, then find the LCM of all the denominators.Then multiply both side of the equation by that LCM.
For example:
[tex]\frac{2}{3}x-\frac{5}{4}=\frac{1}{2}[/tex]
Here denominators are 3,4 and 2. So the LCM of them is = 12
Multiply both sides by 12.
[tex]12(\frac{2}{3}x-\frac{5}{4})=12(\frac{1}{2})\\8x-15=6[/tex]
If the equation has decimal, then count the maximum number of places after decimal. Then multiply by "1 and then that many zeros".
For example: 0.324x - 0.92 = 0.526
Here maximum number of places after decimal is = 3.
So we will multiply both sides by 1000.
1000(0.324x - 0.92) = 1000(0.526)
324x - 920 = 526

Answer:
Angle sum property of a triangle is 180°
So,
Angle T + Angle U + Angle V =180°
(5x +7) + (2x + 7) + (6x + 10) = 180 °
5x + 7 + 2x + 7 + 6x + 10 = 180°
13x + 24 = 180 °
13x = 180 - 24
13x = 156
x = 156/13
X = 12
Angle U = 2x + 7 = 24 + 7 = 31
Angle T = 5x +7 = 60 + 7 = 67
Angle V =6x + 10 =72 +10 =82
For second questionx + x + x =3x
And according to the theorem of triangle of sum
3x = 180 °
x = 180 / 3
x = 60°

purchase furniture of rs.50000 at 10% discount (accounting equation
Answer:
5000
Step-by-step explanation:
50000 / 10= 5000
Cost of the furniture of 50000 rupees with 10% discount is 45000 rupees
What is Discount?A deduction from the usual cost of something
Here Cost of the furniture = 50000 rupees
Discount = 10%
Then the discount price is = total cost × 10%
[tex]50000(\frac{10}{100})=5000[/tex] rupees
Then the purchased amount = Total price - Discount

What slope would make the lines
parallel?
y = -3x + 9
y = [?]x + 4
Answer:
- 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 9 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + 4 ← is the equation of a parallel line

Consider the enlarged triangle.
A smaller triangle has side lengths 4, 5, 3. A larger triangle has side lengths 8, 10, 6.
Which steps should be used to find the perimeter? Check all that apply.
Find the scale factor: enlarged over original = 6 over 3 = 2
Find the scale factor: enlarged over original = 3 over 6 = one-half
Calculate the perimeter of the original figure.
Divide the perimeter of the original figure by the scale factor.
Multiply the perimeter of the original figure by the scale factor.
Find the scale factor: StartFraction enlarged over original EndFraction = StartFraction 6 over 3 EndFraction = 2
Calculate the perimeter of the original figure.
Multiply the perimeter of the original figure by the scale factor.
Step-by-step explanation:
A, C, D
The steps which could be used to find the perimeter are Find the scale factor: enlarged over original = 6 over 3 = 2, Calculate the perimeter of the original figure and Multiply the perimeter of the original figure by the scale factor.
What is Scale Factor?Scale factor is the ratio of the dimension of the given original object and the dimension of the new object from the original.
Given that,
A smaller triangle has side lengths 4, 5, 3. A larger triangle has side lengths 8, 10, 6.
First find the scale factor.
Scale factor of enlarged over original = 8/4 = 10/5 = 6/3 = 2
Now, find the perimeter of the original figure.
Perimeter of the original figure = 4 + 5 + 3 = 12
Now.
Perimeter of enlarged figure = Scale factor × Perimeter of original figure
= 2 × 12
= 24
Hence the correct steps are first, third and last step.
