There are 6 times as many males as females on the maths course at university. What fraction
of the course are male?
Give your answer in its simplest form.

Answers

Answer:

Fraction of females enrolled in the course = 6 / 7

Step-by-step explanation:

Suppose that

Total Number of males = x  

Total Number of females = 6x  

Total Number of Students = 6x + x = 7x  

Now, we have to find the what fraction of the course females candidates constitute.  

Female Fraction = Total Females : Total Students  

Female Fraction = 6x : 7x  

Female Fraction = 6 : 7  

Female Fraction =  6 / 7

So Total number of females enrolled in the course constitute the fraction = 6 / 7

HELP ASAP!!! Make t the subject of 5(t − g) = 2t + 7

Answers

Answer:

t=(7+5g)/3

Step-by-step explanation:

5(t-g)=2t+7

5t-5g=2t+7

5t-2t=7+5g

3t=7+5g

divide both side by 3

t=(7+5g)/3

As per linear equation, the variable 't' is subject of 5(t -g) = 2t + 7 as  [tex]t = \frac{5g + 7}{3}[/tex].

What is a linear equation?

"A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.

There are linear equations in one variable and linear equations in more than one variable. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."

The given linear equation is:

5(t - g) = 2t + 7

We can calculate the value of the variable 't' by keeping it in the left hand side of the equation and then rest of the elements on the right hand side of the equation. Now we get:

⇒ 5t - 5g = 2t + 7

⇒ 5t - 2t = 5g + 7

⇒ 3t = 5g + 7

⇒ [tex]t = \frac{5g + 7}{3}[/tex]

Therefore, the value of the variable 't' in terms of the variable 'g' is  [tex]t = \frac{5g + 7}{3}[/tex].

Determine which of the lines, if any, are parallel. Explain.
Line a passes through (-1, - 2) and (1,0).
Line b passes through (4, 2) and (2, – 2).
Line c passes through (0, 2) and (-1,1).
The slopes are

Answers

Answer:

Line A and Line C are parallel

Step-by-step explanation:

Slope Equation: [tex]m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Step 1:  Find the slope of the first line

Line a passes through (-1, -2) and (1, 0).

[tex]m = \frac{(0- (-2))}{(1 - (-1))}[/tex]

[tex]m=\frac{2}{2}[/tex]

[tex]m=1[/tex]

Step 2:  Find the slope of the second line

Line b passes through (4, 2) and (2, -2).

[tex]m = \frac{(-2- 2)}{(2 - 4)}[/tex]

[tex]m = \frac{-4}{-2}[/tex]

[tex]m=2[/tex]

Step 3:  Find the slope of the third line.

Line c passes through (0, 2) and (-1, 1).

[tex]m=\frac{(1-2)}{(-1 - 0)}[/tex]

[tex]m=\frac{-1}{-1}[/tex]

[tex]m=1[/tex]

16 pi is area = 50.2655 units^2 (to 4dp)

Answer:

50.24

Step-by-step explanation:

Area of the circle is [tex]\pi r^{2}[/tex]. If the diameter is 8, then we know that the radius is 4, because the radius is half of the diameter. Then solve. 4 squared is 16, then multiply by 3.14 in place of pi and you will get 50.24. So yes, you are correct, it is 50.24.

A membership at Gisele’s Gym costs $145 to join and $3 for each visit. A membership at Freddie’s Fitness costs $75 to join and $5 for each visit. Which location has a lower total cost for different numbers of visits? Write each number of possible visits from the box into the correct column in the table to show whether one location has a lower total cost, or the same total cost as the other location.

Answers

Step-by-step explanation:

You can do the equation 145+3v for Gisele’s Gym

For Freddie’s Fitness do the equation 75+5v and put in the number of visits for v

For example, for 33 visits Freddie’s fitness has a lower cost than Gisele’s gym. You could do 3x33 + 145 = ? for Gisele’s gym, and do 5x33 + 75 for Freddie’s Fitness, and then compare which one has a lower cost. But technically I just gave you one answer and shown you what you could do.

I’m not particularly sure if I’m correct but that’s how I would do it, sorry for the long wait, if you have any questions you can ask me :)

8: 1, 2, 4, 8

12: 1, 2, 3, 4, 6, 12

Cone:

r = 8/2 = 4 ft

h = 16 - 12 = 4 ft

Volume = [tex]\frac{1}{3}\pi r^{2}h\\[/tex]

             [tex]= \frac{1}{3}*3.14*4*4*4\\\\=\frac{200.96}{3}\\\\= 66.98\\\\= 67 cubic feet\\[/tex]

Cylinder:

r = 4 ft

h= 12 ft

Volume = πr²h

              = 3.14*4*4*12

            = 602.88

           = 603 cubic feet

Step-by-step explanation:

the formular for finding the volume( how much it can contain in this instance) of the cone(spout) is

[tex] \frac{1}{3} \times \pi \times {r}^{2} \times l[/tex]

r is the radius of the cone l is the height of the cone π = 22/7

1/3 × 22/7 × 4 × 4 × 4

diameter divide by 2 gives the radius 8/2 = 4

the height of the whole shape - the height of the upper part(cylinder) gives the height of the cone

16 - 12 = 4

volume of spout(cone)=22/21 × 64 =67 cubic feet(f^3)

the second question is correct because the picture shows you that they start out with 3/5 because they are highlighted green. and they cross out 2 1/5 or 2/5. that is why 3/5-2/5=1/5
