Answer:

Decimal Form: 1.3

Exact Form: 13/10

Mixed Number Form: 1 3/10

Step-by-step explanation:

1 pint = 2 cups

Convert the mixed fraction into an improper fraction. 2 3/5 = 13/5 cups

You divide 13/5 by 2, since there are 2 cups in one pint, and you are trying to get pints. 13/5 divided by 2:

Decimal Form: 1.3

Answer:

x = 30, 150, 210, 330 degrees.

Step-by-step explanation:

(sin x)^2 = 1/4

sin x = +/- √1/4

sin x = +/- /2

In the first quadrant  x =  angle whose sine is 1/2 = 30 degrees.

There is also a solution in the other 3 quadrants.

In second quadrant  where sine = 1/2  , x = 180-30 = 150 degrees,

In 3rd and 4th where sine x = -1/2 the angles are 210 and 330 degrees.

Answer:

one side = [tex]\frac{a\sqrt{2}}{2}[/tex]

Step-by-step explanation:

if you draw an octagon on a piece of paper, you can draw a square around it, you should be able to see a diagram of this attached, ignore the 6.

Let's say TP = a

since it's a regular octagon, TP = HT

and using the Pythagoras Theorem,  we know a² + b² = c² and thus:

√(AT² + HA²) = HT

and since AT = HA which we will call x, the equation becomes:

√(2x²) = HT = a

rearrange the equation to solve for x and you get:

2x² = a²

x² = [tex]\frac{a^{2} }{2}[/tex]

x = [tex]\frac{a}{\sqrt{2}}[/tex]

which, if you rationalise the denominator, you get:

x = [tex]\frac{a\sqrt{2}}{2}[/tex]

Answer:

6 students

Step-by-step explanation:

first you wanna convert the 2/3 into 4/6 cause that makes it easier then add the 1/6 to it  making it 5/6 and finally 5/6 of 36 is 30 and 36-30=6

Answer:

6 students

Step-by-step explanation:

Blue shirts: 1/6*36 = 36/6= 6

white shirts: 2/3*36= 72/3= 24

Blue + white= 24+6= 30 Students

36-30= 6 students didn't wear blue or white

Answer:

x=7.965784

Step-by-step explanation:

Answer:

1) 243 in.²

Step-by-step explanation:

1)

A = 18 in. * 18 in. - 9 in. * 9 in. = 243 in.²

Answer:

8x+5 + 2x+5 = 180

10x+10=180

10x =170 = x = 17

Step-by-step explanation:

Answer:

answer: x = 17 Hope this helps!

2 x 17 + 5 = 39 8 x 17 + 5 = 141

Straight angles are 180 degrees

39 + 141 = 180

So x = 17

Answer:

3 5333/10,000

Step-by-step explanation:

Answer:

speed of motorcycle = 40 mph

speed of car = 50 mph

Step-by-step explanation:

Here is the complete question

A car and a motorcycle leave at noon from the same location, heading in the same direction. The average speed of the car is 30 mph slower than twice the speed of the motorcycle. In two hours, the car is 20 miles ahead of the motorcycle. Find the speed of both the car and the motorcycle, in miles per hour.

Speed = distance / time

This question would be solved using simultaneous equation

let m =  average speed of the motorcycle

c = average speed of the car

c = 2m - 30  equation 1

20 =(c - m) x 2 equation 2

insert equation 1 into equation 2 and divide through by 2

10 = (2m - 30) - m

solve for m

m = 40 mph

substitute for m in equation 1

2(40) - 20 = 50 mph

Answer:

Plan ahead for medical expenses.

Spend your money.

Save your receipts.

Use your FSA to pay expenses your health plan doesn't cover.

Use your FSA to reach health plan financial milestones.

Know what your FSA covers.

Know your FSA balance.

Step-by-step explanation:

Answer:

Okay so I just took the FSA and my biggest tip is  to just relax and don't overthink. Another tip that is kinda weird is to  chew gum/mint. They normally hand it out to you but stopped for coronavirus.  It helps you focus and it helps calm you. Make sure you double check your answers and if you don't know a question go back over it and re read it.  Also pay attention to other questions because sometimes a question from the same passage helps you with a previous one.  You're going to do well and good luck!
