In a comection with a criminal investigation
the police question of men allot whom are
tall, slim or bald, There are 32 tall men , 20
who are tall and slim 23 who are tall
and bald, 24 who are slim and bold
6 who are slim but not tall a bold
and a who are tall but not slim or bald.
Find the number of men questioned who have
all three characteristics
b) work out the number who are bald but
not tall a silm.
Answer:
We have
n[T]=4+20-x+x+23-x
32=47-x
x=47-32
x=15
so
the number of men questioned who have
the number of men questioned who haveall three characteristics is 15.
again
n[S]=6+20-x+x+24-x=50-x=50-15=35
again
we have
n[U]=n[T]+n[s]+N only [ B]
54=32+35+N only [ B]-n[T and S]
N only [ B]=54-67+20=7
who are bald but
who are bald butnot tall a slim is 7.

In ΔSTU, t = 3.4 cm, u = 6.9 cm and ∠S=21°. Find the area of ΔSTU, to the nearest 10th of a square centimeter.
Answer:
4.2
Step-by-step explanation
Delta
The area of the triangle STU to the nearest of a square centimeter is 4.2 cm².
Area of a trianglearea of the triangle = 1 / 2 tu sin S
where
height = u sin STherefore,
t = 3.4 cm
u = 6.9 cm
∠S = 21°
Hence,
area of the triangle = 1 / 2 × 3.4 × 6.9 sin 21°
area of the triangle = 23.46 sin 21 / 2
area of the triangle = 23.46 × 0.35836794954 / 2
area of the triangle = 8.40731209633 / 2
area of the triangle = 4.20365604817
area of the triangle = 4.2 cm²

I did the work, and basically i solved for the area of the faces and then multiplied that by two to get the total surface area of the faces. Then I added in the areas of the sides connecting the two faces:
just as a referral: the formulas to find the faces are as follows:
rectangle: length times width

trapezoid: h(base1 + base2)
and triangle: (b x h)/2
1. You go to the local Sport Grill for quarter wings day.
All chicken wings are $0.25. Your waiter also announces
that for your stay there will be an additional 20%
discount on wings. Your table of friends stays there for
2 hours and eats a total of 78 wings. How much do you
expect the bill to be for your wings?
na
Answer:
If the 20% discount is by the hour then the answer would be $11.70 I think.
0.25x78= 19.50
19.50x0.20(20%)= 3.90
19.50-3.90-3.90= 11.70

Step-by-step explanation:
A train travels 120 mi in 1 hour and 20 minutes. How many miles will the train go in 6 hours traveling at the same rate?
Answer: 541.32 miles
Step-by-step explanation:
First find the speed of the train in miles per hour.
1 hour 20 minutes needs to be converted to decimal:
= 1 20/60
= 80/60
= 1.33 hours
Speed is:
= Distance / Time
= 120/ 1.33
= 90.22 miles an hour
If the train is traveling 6 hours at the above speed, it will travel:
= Speed * time
= 90.22 * 6
= 541.32 miles

Answer:
One proportion to solve is 8/18 = x/8Exact answer as a fraction: x = 32/9Approximate answer in decimal form: x = 3.556In reality, the 5's go on forever, but we have to round off somewhere.
========================================================
Explanation:
Break up the triangles as your teacher recommends. See the diagram below as to what I mean.
The smaller triangle has A = 8 as the horizontal side, and B = x as the vertical side
The larger triangle has C = 10+8 = 18 as the horizontal aside, and D = 8 as the vertical side.
We can form the proportion A/C = B/D.
A/C connects the horizontal sides (small/large) while B/D has the vertical sides tied together. The order of division is the same small over large. You could do large over small, but make sure you keep both sides consistent.
-----------------
Let's solve for x
A/C = B/D
8/18 = x/8
8*8 = 18*x .... cross multiply
64 = 18x
18x = 64
x = 64/18 .... divide both sides by 18
x = 32/9 exactly in fraction form
x = 3.556 approximately in decimal form
-------------------
Another proportion you can solve is A/B = C/D and you should get the same x value. It's the same as A/C = B/D because the B and C swap places. There are many other approaches you could take using different proportions.

Plot the following fractions and decimals on the number line.
0.7 ,1/3 ,8/7,0.4 ,0.125, 5/6
(number line, the best i can do)
0---------1/4--------1/2---------3/4--------1
The following fractions and decimals on the number line.
0__0.125__1/4__1/3__0.4__1/2__0.7__3/4__5/6__1__8/7
What is number line?A straight line with numbers placed at equal intervals or segments along its length.
First,
0.7= 7/10, which is a less than 3/4 0.75
so, lies in between 3/4 and 1
second,
1/3 is larger than 1/4 but smaller than 1/2,
so is lies in between 1/4 and 1/2.
third,
8/7, greater than 1, so goes right in front of 1.
fourth, 0.4=4/10, less than 1/2 and greater than 1/3,
so lies in between 1/2 and 1/3.
Fourth,
0.125 = 1/8, is the smallest,
which means its last, half between 1/4 and 0.
5/6 is the second largest
Hence, 0.125<1/4<1/3<1/2<0.7<3/4<5/6<1<8/7

3.1289
8.5763
9.0909
11
Answer:
The answer is 9.0909
Step-by-step explanation:
n=1 p=.11
mean = 1/0.11 = 9.0909
The mean of X, the number of patients seen until an injection-site reaction occurs is 9.0909.
What is mean?The mean refers to "the average set of values".
According to the question,
The percentage of patients experiencing injection- site reactions with the current needle is 11%.
Mean = [tex]\frac{sum of the all values}{Total number of values}[/tex]
Total number of values = 11% = 0.11 and n = 1.
Mean = [tex]\frac{1}{0.11}[/tex]
=9.0909.
Hence, the mean of X, the number of patients seen until an injection-site reaction occurs is 9.0909.

Judy and 2 friends won $145.00 at a fundraising raffle! They agreed to share the winnings equally. They received one $100 bill, four $10 bills, and five $1 bills
Answer:
There are 3 friends (Judy + 2 friends) who won $145.00
They want to share the winnings equally, but they got:
one $100 bill
four $10 bills
five $1 bills.
Assuming that they can share only those bills, the only way to share the winnings equally is:
Each friend gets one $10 bill
Each friend gets one $1 bill
Then each one gets $11.
And there is a surplus of:
one $100 bill (that can't be divided)
one $10 bill (that can't be divided)
two $1 bill (that can't be divided)
Then:
There is a common pool of $100 + $10 + 2*$1 = $112
And each one of the 3 friends gets $10 + $1 = $11
In the case where they can change the bills, each friend will get:
$145/3 = $48.33
