There are 130 people in a sport centre.
61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
Given that a randomly selected person uses the gym and the track, what is the probability they do not use the swimming pool?
Answer:
13 / 19
Step-by-step explanation:
Given that :
U = 130
Let :
s = swimming pool
t = track
g = gym
n(g) = 61 ; n(s) = 68 ; n(t) = 60
n(g n s) = 25 ; n(t n s) = 30 ; n(g n t) = 19
n(g n s n t) = 6
n(g n t) only = n(g n t) - n(g n s n t) = 19 - 6 = 13
Hence, probability that a randomly scted person uses the gym and track and does not use the swimming pool = n(g n t) only ÷ n(g n t)
= 13 / 19
= 13 / 19

In figure below alb, m<1 = 78°, and m<2 = 47°.
Find measure of each angle.
Answer:
m∠3 = 102°
m∠4 = 102°
m∠5 = 78°
m∠6 = 133°
m∠7 = 47°
m∠8 = 47°
m∠9 = 133°
m∠10 = 102°
Step-by-step explanation:
Lines a and b are parallel and
m∠1 = 78° and
m∠2 = 47°
m∠3 = 180 - m∠1 = 180 - 78 = 102°
m∠4 = m∠3 = 102°
m∠5 = m∠1 = 78°
m∠6 = 180 - m∠7 = 180 - m∠2 = 133°
m∠7 = m∠2 = 47°
m∠8 = m∠2 = 47°
m∠9 = 180 - m∠8 = 180 - 47 = 133°
m∠10 = 180 - m∠1 = 102°

Step-by-step explanation:
We don't know Steve's age, so make his age=x. If his parrot is 19 years old and he's 7 years older than Steve, you would be adding 7 years onto Steve's age. So, to do that it would be x+7=19 or B!
The perimeter of a rectangle is 52 feet. The length is 2 more than twice the width. What is the length of the rectangle?
Answer: The Length of the rectangle is 18 feet.
The width is 8 feet
Step-by-step explanation: Perimeter is 2w + 2L
Length here is 2w + 2 Substitute this value for L in the equation.
P = 2w + 2L
52 = 2w + 2(2w + 2) distribute and add
52 = 2w + 4w + 4
52 = 6w + 4 Subtract 4 from both sides, Then divide both sides by 6 to solve for w
48 = 6w
8 = w The width is 8 ft
Substitute into the original expression for Length
Length here is 2w + 2 : 2(8) + 2 16 + 2 = 18
The Length is 18 feet.
Check: in the original equation P = 2w + 2L
52 = 2(8) + 2(18)
52 = 16 + 36 TRUE!
Answer:
The length would be 18ft the width would be 8ft

What is the area of a rectangle with the length of 15.2 inches and a width of 5.05 in. SHOW YOUR WORK and line them up
Final Answer: [tex]A[/tex] = [tex]76.76[/tex] [tex]in^2[/tex]
Steps/Reasons/Explanation:
We will be trying to find the area of the rectangle. The formula tells us to multiply width times length. This means that we will multiply our length of 15.2 inches by a width of 5.05 inches to find the area of a rectangle.
The final answer would include [tex]in^2[/tex] because we are multiplying both inches of the length and width to find the area.
Question: What is the area of a rectangle with the length of 15.2 inches and a width of 5.05 in?
Rectangle Area Formula: [tex]Area[/tex] = [tex]width[/tex] × [tex]length[/tex]
[tex]A[/tex] = [tex]15.2[/tex] inches × [tex]5.05[/tex] inches
[tex]A[/tex] = [tex]76.76[/tex] [tex]in^2[/tex]

I NEED HELP ,PLAESE AYUDAAAAA POR FAVOR
Answer:
Step-by-step explanation:
First off, if side BC and side EC are congruent, then this is an isosceles triangle. It then goes to follow by the Isosceles Triangle Theorem that angle EBC is also 67 degrees. By the Triangle Angle-Sum Theorem then, angle BCE is 180 - 67 - 67 which is 46 degrees. Angle BCE is supplementary to angle FCA which means they add up to equal 180, so angle FCA is 180 - 46 = 134.
Angle FCA = 134
, Natasha worked 7 hours at a diner for $10 per hour last week. She also makes $8 per hour when she babysits. She wants $206 for a prom dress. Create an inequality to show how many hours she must babysit.
Answer: x ≥ 17
Step-by-step explanation:
We know that she worked 7 hours at a dinner, for $10 per hour last week.
Then in the last week, she did make:
7*$10 = $70
Now she babysits, she wins $8 per hour, then if she works x hours, she will win:
w(x) = $8*x
if we add the $70 that she already had, we have:
$70 + $8*x
And we know that she wants to have, at least, $206, then we can write the inequality.
$70 + $8*x ≥ $206.
Now let's solve this for x.
first, we can subtract $70 in both sides:
($70 + $8*x) - $70 ≥ $206 - $70
$8*x ≥ $136
now we can divide by $8 in both sides:
($8*x)/$8 ≥ $136/$8
x ≥ 17
This means that she must babysit for at least 17 hours if she wants to buy the dress.

1. John Smith has a past due balance of $80 on his account. He called today to pay off his balance in full. You receive 25% commission of his payment to go toward your budget. What is your total commission received from John's payment?
Answer: $20
Step-by-step explanation:
From the question, we are informed that John Smith has a past due balance of $80 on his account and out of the $80 paid, 25% will be given as commission.
Therefore, the total commission received from John's payment will be:
= 25% × $80
= 25/100 × $80
= 0.25 × $80
= $20
The commission is $20
