Answer:

There are 14 groups of \frac{1}{2} days are in 1 week.

Step-by-step explanation:

To find : How many groups of \frac{1}{2} days are in 1 week ?

Solution :

We know that,

1 week = 7 days

1 day =\frac{1}{7} week

\frac{1}{2} day =\frac{1}{2}\times \frac{1}{7} week

\frac{1}{2} day =\frac{1}{14} week

i.e. there are 14 groups of \frac{1}{2} days are in 1 week.

marin [14]

Answer:

32.761 %

Step-by-step explanation:

Percentage is any fraction or ration expressed as a fraction of 100.

Percentage is calculated using formula

If A has to be expressed as percentage of then it can be expressed as

A/B * 100 in percentage form .

For given problem price paid for sweater = $36.20

original price of sweater = $90.50

Problem is to express percentage of price for which sweater was on sale for.

It can be mathematically  expressed as

what is 36.20% of 90.5

percentage of price for which sweater was on sale for = (price paid for sweater/original price of sweater  ) * 100

It can be mathematically  expressed as

what is 36.20% of 90.5

=>  ($36.20/$90.50 )* 100= 32.761.

32.761 % of the original price sweater was on sale for.

For better understanding ,It can also be said that that if the original price of sweater had been $100, then you would have got it at $32.761 .

Select the angle that correctly completes the law of cosines for this triangle. 72 + 252 – 2(7)(25)cos ___ = 242 A. 180° B. 90°
meriva

Answer:

x =76.45 degrees

Step-by-step explanation:

72 + 252 – 2(7)(25)cos _x__=242

combine like terms

324-350cosx = 242

subtract 324 from each side

-350x = -82

divide by -350

cos x = -82/-350

cos x = 82/350

take the arccos of each side

arccos (cos x) = arccos (82/350)

x =76.45 degrees

What is the total amount of sap trees produced that day? Please tell me ASAP(as soon as possible) because this lesson is due for
gogolik [260]

Answer: 5 gallons


Step-by-step explanation:

There are 3 x's on the graph for 1/4, so 1/4 times 3=3/4

There are 2 x's on the graph for 3/8, so 3/8 times 2=3/4

There are 4 x's on the graph for 5/8, so 5/8 times 4=5/2

There is only 1 x for 1, so it will remain 1.

So if you add these up,

3/4+3/4+5/2+1

6/4+10/4+1

16/4+1

4+1

There is 5 gallons of sap produced that day.

Hope this helped!
