Answer:
50.27 (to 2dp)
Step-by-step explanation:
radius = 4
area of circle = pi * r * r
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.

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.
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
Cole has 12.4 meters of string. How
many feet of string is this?
Answer:
so practically, the only thing that we would do would be doing is converting the meters to feet 12.4 meters convert to feet would be 40.6 ft :)
Answer: To be exact, about 40.68241 feet, you can round to the nearest hundredths place to get 40.67

Step-by-step explanation:
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.
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 :)

Answer:
D
Step-by-step explanation:
To solve this problem, we need to find the greatest common factor of 8, 12, and 16. Let's list out the factors of each number.
8: 1, 2, 4, 8
12: 1, 2, 3, 4, 6, 12
16: 1, 2, 4, 8, 16
We can see that the greatest factor that all three numbers share is 4, so 4 is the GCF.
CAN ANYONE PLS HELPPP ME!!!!!!!!!! ITS DUE!!
Answer:
I agree with Mary
Step-by-step explanation:
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)
Please helppp i will ly 4ever (with both)
Answer:
your answers are correct :)
Step-by-step explanation:
Answer:
those are both correct the awnser thar you have put.
the first question asks what is write the sum as a unit fraction. the unit fraction is 1/10 because it is how you show any unti fraction like 1/20 or 1/100. and 1/10+1/10+1/10=3/10 and is using unit fractions.
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
Hope this helps!
HELP ASAP!!! Make t the subject of 5(t − g) = 2t + 7
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].

The slopes are
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]

L= 90, M=53, K=37
Step-by-step explanation:
Tilt your phone/computer to the right, and you'll see the 90° angle for L. Now you're left with two more, and just compare which angle is bigger, K or M. M is bigger, so you apply the bigger number out of the you got which is 53. Now no doubts, K is 37.

- means you go to the left on a graph (if the number is in the x position) or down on a graph (if it's a negative in the y's place) in this case it's a negative 3 in the x's place so we go left 3 times. Then we go up 4 where we will meet the C coordinate.
