You can:

1. Go to bed early enough so when you wake up in the morning you're energized.

2. Look over your notes. If you've studied a lot, just ask someone to ask you questions about what you've learned. Then go back and try to solve a couple problems.

3. Eat a good breakfast, (though that's the day of the exam, it could help you feel energized and to help you feel like you know what you're doing.)

4. GET OFF THAT ELECTRONIC! That will just distract you, so put it away until tomorrow.

5. Tell yourself that you CAN do this, and you won't fail.

6. Prepare some fidgets if you get fidgety during the exam.

7. Prepare supplies. (i.e. freshly sharpened pencils, a calculator, anything you may need.)

8. Sit in a quiet place for a couple minutes and write down what thoughts might weigh you down and dampen your confidence tomorrow during the exam. Once you're done, rip up the paper and throw it in the recycle bin. Forget those thoughts and throw them in your mental trash can.

GOOD LUCK ON YOUR EXAM!

A rectangle has the length of 2x+7 and the width of 9x find the area and the perimeter
seraphim [82]

Answer:

see explaination

Step-by-step explanation:

length (l) = 2x+7

width (b) = 9x

area of rectangle = l×b

=(2x+7)(9x)

=18x^2+63x

perimeter of rectangle = 2(l+b)

=2(2x+7)(9x)

=2(18x^2+63x)

=36x^2+126x

I marked all 3 parts. I need to know part C (the shaded part). anybody mind helping?​
Mnenie [13.5K]

Answer:

Area of shaded part ABCEF = 66 sq.cm

Step-by-step explanation:

AB = 8cm

CD = 8cm

Let DE = x cm

CE = 3x cm

CD =  CE + DE = 8cm

        x + 3x = 8

4x = 8

x = 8/4 = 2 cm

DE = 2cm

CE = 3 * 2 = 6 cm

Area of triangle ADE = 1/2 * base * height

                                   = 1/2 * DE * AD

                                    = 1/2 * 2 * 11 = 11 sq. cm

Area of triangle AEF = Area of triangle ADE = 11 sq. cm

Area of Rectangle ABCD =  l * b = 8 * 11 = 88 sq.cm

Area of shaded part ABCEF =  Area of Rectangle ABCD - (Area of triangle AEF + Area of triangle ADE)

    = 88 - ( 11 + 11 )  = 88 -22 = 66 sq.cm

Find the area of the figure.
Nady [450]

Answer:

Explanation:

So you want to start by finding the area of the big square.

We know the width to the big square is 60cm. The length to the big square is

19

+

24

+

13

=

56

Big square

A

r

e

a

=

L

⋅

W

=

56

⋅

60

=

3360

Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.

Little square

A

r

e

a

=

L

⋅

W

=

24

⋅

34

=

816

The area enclosed is the area of the big square minus the area of the little square.

3360

−

816

=

2544

So the area enclosed is

2544

A teacher randomly assigns her 30 students 4-digit I.D. numbers using the digits 0 to 9. No digits are repeated within an ID num
Olin [163]
The number of ways 4 digit numbers can be forms using the digits 0 to 9 with no number repeated is given by

^{10}P_4= \frac{10!}{(10-4)!} = \frac{10!}{6!} =10\times9\times8\times7=5,040

The probability that one of the numbers is 9876 is given by \frac{1}{5,040}
