Answer:

Please read all of this! Underlined things are the answers. The area of the entire circle is 19.625

Step-by-step explanation:

(This is a circle so the middle line is the diameter. According to the attachment, the diameter is 5 cm. To find the area, we have to multiply π and the radius squared. The radius is half of the diameter.

5 ÷ 2 = 2.5

2.5² = 6.25

π = 3.14

3.14 x 6.25 = 19.625)

Ignore the top I just realized what I'm supposed to do but I left it there just in case you need help!

<u>The right and left shaded regions areas are 6.28 each.</u>

4 ÷ 2 = 2

2² = 4

3.14 x 4 = 12.56

Since this is a semi circle, we cut it in half.

12.56 ÷ 2 = 6.28

To find the top and bottom shaded region's areas, repeat the same steps.

3 ÷ 2 = 1.5

1.5² = 2.25

3.14 x 2.25 = 7.065

7.065 ÷ 2 = 3.5325

<u>The areas of the the top and bottom shaded regions are 3.5325 each.</u>

-2(t + 4 2/3) = 9 1/2
kiruha [24]
So you times the -2 with the bits inside the bracket so:
-2 x t= -2t
-2 x 4 2/3 = -9 1/3
So then that makes:
-2t - 9 1/3= 9 1/2
So to get what t equals you have to get it by itself so you add the -9 1/3 to both sides of the equation to get:
-2t=18 5/6
So then you divide by -2 on both sides to get
t=-9 5/12
Which is the answer. :-D

Remember that to express an inequality, are used ( ) and [ ].

(  ) are used when the point is not consider in the interval.

[  ]  are used when the point is consider or is part of the interval.

Also, an empty point indicates that the number is not consider in the interval.

and, a filled point indicates that the number is consider in the interval.

For your question, the interval will be:

HELP ME PLS, I'M BEGGING U!!!!!!!<br> GEOMETRY QUESTION!!!!!!
ANEK [815]
Use the 30* 60* 90* rule where

30* = x,   60* = x√3,   90* = 2x

so based on the given, 
2x = 6√3 ⇒ divide both sides by 2 and you'll end up with
x = 3√3 (the length side of JK)

to find JL, multiply 3√3 by √3 and the answer'll be 9 = length of JL, opp of 60*

A restaurant has a 3/4 pan of lasagna.if the cost is 20 dollars per 1/3 of a pan ,how much for the 3/4?
kumpel [21]

Answer:

3/4 pan of lasagna costs $45.

Step-by-step explanation:

The cost of 1/ 3 pan of lasagna = $20

The amount of lasagna available in restaurant = 3/4 pan

Now cost of 1/3 pan lasagna = $20

So, the weight of 1 full pan =3 \times  {\textrm{The cost of }}(\frac{1}{3}) {\textrm{pan of lasagna}}

=   3 x$ 20 = $60

⇒ 1 complete pan costs $60

So, 3/4 pan costs \frac{3}{4}  \times 60 = 45

Hence, 3/4 pan of lasagna costs $45.
