Answer:

Step-by-step explanation:

The house is split into two cubes: The main house, and the "chimney"

The volume of the main part of the house is 20*20*21 mm=8,400mm cubed

The chimney's volume = 11*5*2mm = 110 mm cubed

Now, you just need to add them up.

8,400+110 mm cubed = 8,510 mm cubed

Lisa and her 17 classmates are donating money to a local charity. Each student will donate $5.25. How much money are Lisa and her classmates donating altogether?

Answers

Answer:

$94.50

Step-by-step explanation:

Total No. of students = Lisa(1) + 17 classmates = 1+17 = 18

Money donated by 1 student = $5.25

Money donated by 18 Students = 18*5.25 = $94.50

$94.50
money donated 1 student=$5.25
17+5.25=$94.50

Answer:

A. 525 in squared

Step-by-step explanation:

Fundamentally, the area of a parellelogram such as this can be calculated the same way the area of a normal rectangle is calculated: Length x Width.

Thus,

(27 + 8) x 15 = Area

35 x 15 = Area

525 = Area

Jaxon is creating a mosaic design on a rectangular
table. He has added two pieces to one of the corners.
The first piece has an angle measuring 38° and is
placed in the corner. A second piece has an angle
measuring 27° and is also placed in the corner. Draw a
diagram to model the situation. Then, write an
equation, and use it to determine the measure of the
unknown angle in a third piece that could be added to
the corner of the table.

Answers

Here are the answers

Astronomers sometimes use angle measures divided into degrees, minutes, and seconds. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Suppose that ∠J and ∠K are complementary and that the measure of ∠J is 45 degrees, 30 minutes, 14 seconds. What is the measure of ∠K?

The measure of ∠K is ______ degrees, ______minutes, and _____ seconds.

Answers

Answer:

Here's what you need to know to answer this question:

            If two angles are "complementary"

            then they add up to 90 degrees.

So now you know that

                                    (Angle-J) + (Angle-K) = 90 degrees .

Subtract (Angle-J)

from each side:                              Angle-K = (90 degrees) - (Angle-J)

    Angle-K  =  (90 degrees) minus (48 degrees 26 minutes 8 seconds)

As soon as you do that subtraction, you have the answer.

The thing that makes it tough is subtracting some minutes

and some seconds from 90 degrees.

How you do that is:  An unusual kind of regrouping ('borrowing').

Usually, when you regroup, you take '1' from a place and use it

to make '10' in the smaller place.

This time, when you take '1' from a place, it gives you '60'

in the smaller place.

-- Take 1 degree away from the 90 degrees.

   Use it to make minutes.

   Then you have                  89 degrees  60 minutes .

-- Take 1 minute away from the 60 minutes.

   Use it to make seconds.

   then you have                    89 degrees  59 minutes  60 seconds .

Now the subtraction is a lot easier.

            89 degrees  59 minutes  60 seconds

minus   48 degrees  26 minutes    8 seconds .

That's easy to do, and the difference is the measure of Angle-K.
