Solve 5y-3=3y+27

Answer:

Step-by-step explanation:

first, since all of the sides are equal, the angles are equal too. in order to find the missing variable, y, we need to make the two equations equal to each other.

5y - 3 = 3y + 27

then, we solve this one. first, we move the terms.

5y - 3y = 27 + 3

then, we collect the like terms.

2y = 30

so, y = 15.

now, we can insert 15 in for y on angle a.

5(15) - 3

that calculates to 72. so, the measurement for angle A is 72 degrees.

now we need to find angle B. we know that there are 360 degrees inside of a parallelogram. so, we subtract 144 from the 360. (since both given angles are the same, they add up to 144. we subtract that from the total, in order to find the other angles.)

360 - 144 = 216

then, we divide 216 by 2, in order to find the two separate angles.

216 / 2 = 108. so, the measurement for angle B is 108 degrees.

How do you write 250% as a fraction, mixed number, or whole number in simplest form?
cupoosta [38]
To find out what a percentage written as a fraction would look like, you first need to convert it into a decimal.
To convert a percentage to a decimal, you either need to divide the percentage by 100, or (my personal shortcut) just move the decimal point over two places to the left.

250% = 2.5

The decimal .5 is equivalent to 1/2, since 50 is half of 100.

250% written as a fraction (well, a mixed number, really) is 2 1/2.
Hope that helped =)

Round 0.117647059 to three decimal places
mina [271]

The number in the third decimal place is bolded bellow:

0.117647059

To determine if you round up or stay the same you must look at the number after the 7. In this case the number after the 7 is 6.

A number will round up if this number (6) is 5 or greater. If it is smaller then 5 then the decimal will not round up.

In this case this means that the 7 will round up to 8...

0.118

Hope this helped!

An Airbus A380 has 1 first class section 1 business class section and 4 economy class sections
Juliette [100K]

Answer:

Yes, more than half are being used.  (292 out of 546 used)

Step-by-step explanation:

The first part of this problem is to determine the total amount of seats on the plane so we can determine what half of the seats would be.

1st class has 14 seats.

Business-class has 64 seats.

And the 4 economy classes have 117 each, meaning 117 * 4 = 468

So the total amount of seats are 14 + 64 + 468 = 546

So half that amount would be 273.

Now we can determine the number of seats being used.

1st class has (6/7) * 14 = 12 seats used

Buisness-class has (7/16) * 64 = 28 seats being used

Economy has 4 * (7/13) * 117 = 4 * 63 = 252 seats being used

So the total amount of used seats would be 12 + 28 + 252 = 292.

Note that 292 is greater than 273, so there is indeed more than half the seats on the plane being used.

Cheers.
