Step-by-step explanation:
[tex] \frac{7}{5} \times \frac{5}{12} - \frac{3}{12} \times \frac{7}{5} - \frac{1}{15} = \frac{7}{5} ( \frac{5}{12} - \frac{3}{12} ) - \frac{1}{15} = \frac{7}{5} \times \frac{1}{6} - \frac{1}{15} = \frac{7}{30} - \frac{2}{30} = \frac{5}{30} = \frac{1}{6} [/tex]

Answer:
Estimated 120 students
Step-by-step explanation:
Hi there!
The survey established that 3 out of the 75 students did not have social media accounts.
[tex]\displaystyle \frac{3}{75}[/tex]
Let [tex]x[/tex] be equal to the number of students in the entire school who does not have social media accounts.
[tex]\displaystyle\frac{x}{3000}[/tex]
Create a proportion:
[tex]\displaystyle \frac{3}{75}=\displaystyle\frac{x}{3000}[/tex]
Multiply both sides by 3000 to isolate [tex]x[/tex]:
[tex]\displaystyle \frac{3}{75}*3000=\displaystyle\frac{x}{3000}*3000\\\\\frac{9000}{75}=x\\\\120=x[/tex]
Therefore, the number of students in the entire school who do not have social media accounts is estimated to be 120.
I hope this helps!

Answer:
12
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos 60 = 6/hyp
hyp = 6 / cos 60
hyp = 6 / (1/2)
htp = 12

Answer:
x= 2/2
Step-by-step explanation:
Find the missing side of the triangle.
A. √226 ft
B. √17 ft
C. √329 ft
D. √346 ft
15^2 = x^2 + 11^2
225 = x^2 + 121
Subtract both sides 121
225 - 121 = x^2 + 121 - 121
104 = x^2
x = √104
x = √4 × 26
x = √4 × √26
x = 2 × √26
x = 2 √26

Answer:
Step-by-step explanation:
Please refer to the picture
The graph is shown in the attachment below
From the graph, the solution to the equation [tex]\frac{4}{x}-2x+1=0[/tex] is x = -1.2 and x = 1.7
From the picture, we are to draw the graph of the function
[tex]y = -\frac{4}{x}[/tex] for the range of values [tex]-3\leq x\leq 3[/tex] (that is for values of x from -3 to 3)
First we will create the table of values for the function
Table of values for the function [tex]y = -\frac{4}{x}[/tex]
x y
-3 1.33
-2 2
-1 4
0 Undefined
1 -4
2 -2
3 -1.33
(Shown better in the docx attachment)
The graph for the function [tex]y = -\frac{4}{x}[/tex] (purple lines) is also shown in the attachment.
To use the graph to solve the equation [tex]\frac{4}{x}-2x+1=0[/tex]
We will rewrite the equation so that it takes the form [tex]y = -\frac{4}{x}[/tex]
From [tex]\frac{4}{x}-2x+1=0[/tex]
Then, [tex]-2x+1= -\frac{4}{x}[/tex]
∴ [tex]y = -2x+1[/tex]
Hence, we will plot the graph for the function [tex]y = -2x+1[/tex] on the same graph and the points of intersection gives the solution.
The function is a linear equation
The points of intersection on the x and y axes (x-intercept and y-intercept) are enough to plot a straight line graph as shown in the table below as well as in the graph
x y
0 1
0.5 0
(Shown better in the docx attachment)
The straight red lines in the graph shows the plot for the function [tex]y = -2x+1[/tex]
From the graph, the points of intersection are -1.2 and 1.7
Hence, the solution to the equation [tex]\frac{4}{x}-2x+1=0[/tex] is x= -1.2 and x = 1.7

Your question is incomplete. It looks like you are referring to this question below:
A gas station has monthly expenses in dollars of 5000+2.2 X. It sells the gas at $2.25 per gallon. How many gallons do they need to sell to make a profit of $3000 per month, if X is the number of a gallons sold.
The given parameters include;
total monthly expenses, t = $(5000 + 2.2x)
number of gallons sold, = x
price of a gallon, p = $2.25
estimated profit in a month, g = $3000
The equation for profit made in a month is as follows;
Total revenue - expenses = profit
2.25x - (5000 + 2.2x) = 3000
2.25x - 5000 - 2.2x = 3000
0.05x = 8000
x = 8000/0.05
x = 160,000 gallons
Therefore, the number of gallons to be sold in order to make the estimated profit in a month is 160,000 gallons.

You work at McDonalds making $9 per hour, this week you are scheduled to work
4:30pm - 10pm Wednesday - Saturday. How much will your gross pay be for the WEEK?
(you are on the clock the entire shift)
Answer:
$198
Step-by-step explanation:
Basically what I did was how long is 4:30 - 10:00 pm (5 hours and 30 minutes)
and multiplied that by your hourly rate. So 5 × 9 = 45, 9 ÷ 2 = 4.5, 45 + 4.5 = 49.5, 49.5 × 4 = 198. And since you don't clock out and this is your gross payment then that is the final answer

Find the amount and the compound interest on rupees 5000 for 2 years at 6% per annum, Interest payable yearly. Answer with full steps and formula NO BAD ANSWERS REQUIRED :D
Answer:
I. Amount = 5618 Rupees
II. Compound interest = 618 Rupees
Step-by-step explanation:
Given the following data;Principal = 5000 RupeesTime = 2 yearsInterest rate = 6%To find the compound interest;
Mathematically, compound interest is calculated using the formula;
A = P(1 + r)^t
Where;
A is the future value.P is the principal or starting amount.r is annual interest rate.t is the number of years for the compound interest.Substituting into the formula, we have;
A = 5000(1 + 0.06)^2
A = 5000(1.06)^2
A = 5000 * 1.1236
A = 5618 Rupees
Next, we would determine the compound interest using the formula;
C.I = A - P
C.I = 5618 - 5000
Compound interest (C.I) = 618 Rupees
Need help ASAP 3(9+9b)=69+136
Answer:
b=3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
b = 3
Step-by-step explanation:
3(9+9b)=69+136
27+27b = 205
27b = 205-27
27b = 178
b = 178/27
*slaps face*
In the comments you said the "136" is "13b" so ok...
3(9+9b)=69+13b
27+27b = 69 + 13b
27+14b = 69
14b = 69-27
14b = 42
b = 3

Can you find the area of the figure?
Answer:
Below
Step-by-step explanation:
First I found the area of the triangle on the right
A = bh/2
A = (9)(4.5) / 2
A = 20.25 ft^2
Next, the area of the rectangle in the middle
A = lw
A = (7.5)(9)
A = 67.5 ft^2
And now the area of the right triangle on the left
A = bh/2
A = (5)(9) / 2
A = 22.5 ft^2
Add em all up : 20.25 + 67.5 + 22.5 = 110.25 ft^2
Hope this helps!
18. If the ratio of males to females in each
of two different mathematics classes
is 5 to 4, is the ratio of males to
females still 5 to 4 if the classes were
considered as one large class instead
of two smaller classes?
Ra
Answer:
Yes, the ratio is still 5:4.
Step-by-step explanation:
If you have a class of 5 males and 4 females, both numbers can be multiplied to get an even bigger class but the same ratio.
For example:
5 x 5 = 25 males
4 x 5 = 20 females
The amount of males to females is 25:20 when simplified (divided by 5) gets you back to your ratio of 5:4. You also can't go under this because the two don't have a way to get simplified without going into decimals. And I don't think decimals are very good with the number of students.
Have a good day! :)

This is a triangle so it = 180
6x + 1 = 180

Subtract 1 from itself so 6x crosses out
Then subract 1 from 180
Which = 179
Now, divide 6 from both sides 6x is crosses out
You are left with x = (the number you got when dividing 179 / 6)

pls ❤ and give brainliest pls
Answer:
x=8
Step-by-step explanation:
For the equation 6x+7=55 subtract 7 from both sides of the equation to get 6x=55-7 55-7 =48 so now you have 6x=48 you need to isolate the variable x by divide both sides by 6 so 6x/6=48/6 you are left with x=8.

Answer:
30. 2x²-x-1=0
or, 2x²-2x+x-1=0
or, 2x(x-1)+1(x-1)=0
or, (x-1)(2x+1)=0
so, x-1 = 0 or, x = 1
and 2x+1 = 0 or, 2x = -1 or, x = -1/2
so, x = 1 and 1/2
31. 3x²-14x=5
or, 3x²-14x-5=0
or, 3x²-15x+x-5=0
or, 3x(x-5)+1(x-5)=0
or, (x-5)(3x+1)=0
so, x-5=0 or, x=5
and 3x+1=0 or, 3x=-1 or, x=-1/3
so, x = 5 and -1/3
