Step-by-step explanation:
it's so easy to get to know
Step-by-step explanation:
Given
f(x) = 2x - 5
f^-1(x) = ?
we know
Let
y = f(x)
Or y = 2x - 5
Now Interchanging the role of x and y we get
x = 2y - 5
or 2y = x + 5
therefore y = (x+5) / 2
Therefore, f^-1(x) = ( x + 5 ) / 2

What is the gross profit margin?The gross profit margin is a profitability raio. Profitability ratios measures the efficiency with which a company generates profit from its asset. Gross profit margin measures the return on sales.
Gross profit margin can be calculated by dividing the gross profit (difference between revenue and cost of goods sold) by revenue (Net sales). It could be expressed as a percentage by multiplying by 100.
Therefore, Gross profit margin = (gross profit ÷ net sales) x 100
Gross profit = $3,320
Net sales = $4,350
Gross profit margin = ($3,320÷$4,350) * 100
0.763 * 100 = 76.3%
4,350 - 3,320 = 1030
That would be 870 dollar.

Answer:
10 degrees
Step-by-step explanation:
For an equilateral triangle, all three angles add up to 180, meaning that each angle is 60 degrees. Knowing that, we can substitute that number in to solve for x.
5x + 10 = 60
5x = 50
x = 10
Answer:
60 because equilateral triangle have 60-60-60 angles
Step-by-step explanation:
but for step by step:
3 (5x+10)=180
15x+30=180
15x= 150
x=10
5x+10= 5(10)+10= 60

Step-by-step explanation:
Starbucks sells their coffee for $3.36 for 24 ounces
OR
Circle K sells their coffee for $2.40 for 16 ounces
Which is a better buy and by how much?
Answer:
Starbucks by 1 cent difference.
Step-by-step explanation:
Divide: 3.36 divided by 24 to find Starbucks. You get 14 cents per ounce
Divide: 2.40 divided by 16 to find Circle K. You get 15 cents per ounce
Compare: Starbucks is cheaper by 1 cent.
Answer:
starbucks is a better by because they each sell one ounce for the same price. from starbucks you get more ounces for the same price as you would at circle k
Step-by-step explanation:
starbucks: 24 / 336 = $0.07
1 ounce sells for about $0.07
circle k: 16 / 240 = 0.066 = (rounded) 0.07
1 ounce sells for about $0.07

The PTA placed a trail marker in the ground every five hundred yards. Every eight hundred yards the PTA set up a water station. What is the shortest distance a runner will have to run to see both a water station and trail marker at the same location?
Answer:
3600.
Step-by-step explanation:
There will be a trail marker at the following distances from the start of the trail.
400,800,1200,1600,2000,2400,2800,3200,3600,4200 and beyond
There will be water stations at the following distances from the start of the trail.
900,1800,2700,3600,4500 and beyond.
The first time that there will be a trail marker and a water station at the same point will be 3600, that is the first multiple of 400 and 900.

H. 10
J. 12
K. 14
How old will saad be when Amina is 18
Answer:
When Amina is 18. Saad would be;
k. 14
Step-by-step explanation:
Let "x" represent Anita's current age and let "y" represent Saad's current age, we have;
Anita's age = 2 × Saad's age
Therefore;
x = 2 × y...(1)
In 4 years, we will get;
x + 4 = 1.5 × (y + 4)...(2)
Substituting the value of x in equation (1) into equation (2), we get;
2·y + 4 = 1.5·y + 1.5 × 4 = 1.5·y + 6
2·y + 4 = 1.5·y + 6
2·y - 1.5·y = 6 - 4 = 2
0.5·y = 2
y = 2/0.5 = 4
Saad's current age = y = 4 years
From equation (1), we have;
x = 2 × y = 2 × 4 = 8
Amina's current age = x = 8 years
When Amina is 18, we have;
18 = 10 + 8 = 10 + x
Therefore, Amina would be 18 in 10 years time from now, from which we have;
Saad would be 10 years + y = 10 years + 4 years = 14 years in 10 years from now
Therefore, when Amina would be 18 years in 10 years from now Saad would be 14 years.
The age of Saad is required when Amina will be 18.
Saad will be K. 14 years old.
Age problemsLet [tex]a[/tex] be the age of Amina
[tex]s[/tex] be the age of Saad
The age of Amina is twice as old as Saad
[tex]a=2s[/tex]
After 4 years Amina will be 50% older than Saad
[tex]a+4=(1+0.5)(s+4)\\\Rightarrow 2s+4=1.5(s+4)\\\Rightarrow 2s+4=1.5s+6\\\Rightarrow s=\dfrac{6-4}{2-1.5}\\\Rightarrow s=4[/tex]
So, Saad is 4 years old currently and Amina is [tex]2\times 4=8[/tex] years old.
They have a gap of 4 years between them.
When Amina will be 18 since Saad is younger his age will be [tex]18-4=14[/tex] years.

A movie theater sells adult tickets for $6 each. Senior citizens receive a discount of $3. One evening the theater sold 400 tickets and took in $2070 in revenue. How many tickets were sold to senior citizens?
Answer:
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Step-by-step explanation:
First, we need to establish a system of equations:
x= number of adults tickets
y= number of senior citizen tickets
x + y= 400
6x + 3y= 2,070
Now, we isolate x in one equation and substitute the value in the other:
x= 400 - y
6*(400 - y) + 3y = 2,070
2,400 - 6y + 3y = 2,070
330 = 3y
110 = y
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Prove:
290 + 110= 400
6*290 + 3*110= 2,070
If the probability that the Islanders will beat the Rangers in a game is 5/6, what is the probability that the Islanders will win exactly five out of seven games in a series against the Rangers?
Answer:
0.234
Step-by-step explanation:
Given that:
Proportion, (p) ; Islanders beat rangers = 5/6 = 0.8333
Probability that islander win exactly 5 out of 7 games
1 - p = 0.1667
Usingbthe binomial distribution formula :
P(x =x) = nCx * p^n * (1 - p)^(n - r)
P(x = 5) = 7C5 * 0.833^5 * 0.1667^2
P(x = 5) = 21 * 0.833^5 * 0.1667^2
P(x = 5) = 0.23405369484362783281917
P(x = 5) = 0.234

Henry has q5 lawns mowed out of total 60 lawns what percent of the laws does. Henry still have to mow
Answer:
Henry still has to mow 75% of the laws.
Step-by-step explanation:
It is given that Henry has 15 lawns mowed out of a total of 60 lawns.
We need to find: What percent of the lawns do Henry still have to mow?
Henry has 60 lawns in total.
He mowed 15 out of them.
The percentage of lawns mow = [tex]\frac{15}{60} \times 100=25 \%[/tex]
Henry mowed 25% of total lawns.
The percent of laws still have to mow = 100%-25%
The percent of laws still have to mow = 75%
Hence, Henry still has to mow 75% of the laws.
