Answer:
First you need to make 3 1/2 into a improper fraction so you multiply 3 x 2 and then add 1 which is 7/2. Next you need to divide it by 5/8. So to divide fraction you have to do K.C.F. (Keep, change, flip). So you keep the 7/2 change the division symbol to a multiplication symbol. and then flip the 5/8 into 8/5. So the whole problem would be 7/2 x 8/5. next you just multiply.
7 x 8 = 56
2 x 5 = 10
next you just need to simplify into the smallest fraction and you can simplify both by 2. So 56 / 2 = 28 and 10 / 2 = 5. That's how the solution is 28/5.
Also, the value of the expression 5 x 8/5 is 25/8.
Answer:
make 3 1/2 into a improper fraction by multiplying the 3 and the 2 in the denominator together and then add 1 in the numerator to get 7 then make it 7/2 since the 2 was the denominator in the mixed fraction. Then keep the 7/2 the same turn the division symbol to a multiplication symbol then turn the 5/8 into 8/5 by flipping it then multiply. 7×8= 56 2×5=10 now you have 56/10 so you need to simplify. 2 is common between 56 and 10 so you multiply 56/10 and 2 together. 56÷2= 28 and 10÷2= 5 so now it is 28/5.

What is the best estimate of the figure below?
Answer:
28.5 in²Step-by-step explanation:
It is assumed you need to find the area of the figure.
The figure comprises of a rectangle with sides of 6 in x 4 in and semicircle with the diameter of 6 in.
The area of the figure:
A = 6*4 + 1/2*3*(6/2)² = 24 + 4.5 = 28.5 in² (put π = 3 just for estimating the area)1/4•8/9•(-3/5)

Two vehicles, a car and a truck, leave an intersection at the same time. The car heads east at an average speed of 30 miles per hour, while the truck heads south at an average speed of 40 miles per hour. Find an expression for their distance apart d (in miles) at the end of t hours.
Step-by-step explanation:
the car distance to the intersection will be
30t (30 miles for every hour).
the truck distance to the intersection will be
40t (40 miles for every hour).
the distance between the car and the truck will always be the Hypotenuse of a right-angled triangle with the legs being the actual distances from the starting intersection.
so, we use Pythagoras :
d² = (30t)² + (40t)² = 900t² + 1600t² = 2500t²
d = sqrt(2500t²) = 50t
so, their distance will increase 50 miles every hour.

Answer:
v = 176
Step-by-step explanation:
Since a fraction is essentially the same thing as dividing one number by another, we can multiply 44 by 4, the denominator of the fraction we are finding the numerator for, and get 176. This fraction is already in negative form, so we don't need to do anything else.

solve for p..........
Answer:
the answer is p = 15
Step-by-step explanation:
first you set the equation to 2p + 9 = 3p - 6
then solve out the equation by adding 6 to both sides
the equation will now look like this, 2p + 15 = 3p
now you subtract 2p from both sides
the equation now looks like 15 = p
I always flip my equations so I can read it better,
p = 15

The number of classified documents has increased approximately linearly from 8.2 million documents in 2001 to 17.4 million documents in 2005. Let n be the number
of documents (in millions) labeled as classified in the year that is tyears since 2000. Find
an equation of a linear model to describe the data.
Answer:
n -8.2 = 2.3(t -1)
Step-by-step explanation:
You are given definitions for the variables t and n, along with two data points:
(t, n) = (1, 8.2) and (5, 17.4)
The slope of the line between these points is ...
m = (y2 -y1)/(x2 -x1)
m = (17.4 -8.2)/(5 -1) = 9.2/4 = 2.3
The equation can be written in point-slope form as ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
n -8.2 = 2.3(t -1) . . . . a linear model describing the data
______
Additional comment
If we eliminate the parentheses and add 8.2, we get the point-slope equation ...
n = 2.3t +5.9

hope helpful ~
Mrs. Chauke's annual income if she earns R32 040 per month is
R384 480
The given parameters are:
Hourly rate = R180
Work time = 8 hours a day
Monthly income = R32040
There are 12 months in a year.
So, the annual income is:
Annual = 32040 * 12
This gives
Annual = 384480
Hence, Mrs. Chauke's annual income if she earns R32 040 per month is
R384 480

Find the apothem of a regular 12-gon (12-sided polygon) if each side is 4.2 cm, and has
an area of 197 sq. cm.
Answer:
7.8 cm
Step-by-step explanation:
The relevant formula is ...
A = 1/2aP . . . . where a is the apothem, and P is the perimeter.
For a regular 12-gon the perimeter is 12 times the side length, so we have ...
P = 12s = 12(4.2 cm) = 50.4 cm
Then the apothem is found from ...
197 cm² = (1/2)a·(50.4 cm)
a = 197/25.2 cm ≈ 7.81 cm
The apothem is about 7.8 cm.
__
Additional comment
A regular 12-gon with a side length of 4.2 cm will have an area of about 197.500 cm². The apothem will be about 7.837 cm. The area of a regular n-gon can be calculated from the side length as ...
A = ns²/(4·tan(180°/n))
Similarly, the apothem will be ...
a = s/(2·tan(180°/n))
let f(x)=|2x+10| and g(x)=|2x-24|. find all the values of x for which f(x)=g(x).
Answer:
8.5
Step-by-step explanation:
two cases:
1) 2x + 10 = 2x - 24, 10 = -24, impossible!
2) 2x + 10 = -(2x - 24)
2x + 10 = -2x - 24
4x = 34
x = 34/4 = 17/2 = 8.5

Of the 44 players attributed to a playwright 11 are comedies 17 are tragedies and 16 are histories if one play is selected at random find the odds against selecting a tragedy
Step-by-step explanation:
since the total number of players is 44, the Universal set will also be 44.
let C be the set for Comedy
let T be the set for Tragedy
let H be the set for Histories
ξ = { 44 }
C = { 11 }
T = { 17 }
H = { 16 }
probability T = (17/44)
odds of selecting T = probability not T
= 1 - probability T
= 1 - ( 17/44)
= 27/44
you need to give the answer as a ratio of odds of selecting T against chances of selecting T;
if out of 44 players, the chances of not selecting T is 27 and the chances of selecting T is 17, then:
odds against selecting random is, 27: 17
that's the answer. hope this helps you!

Jeff has 242 DVDs. He has 2 shelves that can each hold 120 DVDs. Does he need to buy another shelf
Answer:
Here's my way
Step-by-step explanation:
he has 242, and 2 shelves for 120
120 + 120 = 240,
which leaves 2 off.
so, either you can put:
"Yes, because he has 2 remaining" (Not recommended)
Or
"No, because he put 240 on the shelves , he can put the other 2 somewhere else" (Recommended)
