Need help with 2 math questions pls help me for 20 points.

Answer:

114 cm²

Step-by-step explanation:

Area of shaded region

= area of circle -area of square

[tex]\boxed{area \: of \: circle = \pi {r}^{2} }[/tex]

Given that radius= 10cm, r= 10cm.

[tex]\boxed{area \: of \: square = side \: \times side}[/tex]

Let the length of a side of the square be x cm.

Applying Pythagoras Theorem,

10² +10²= x²

100 +100= x²

x²= 200

[tex]x = \sqrt{200} [/tex]

Area of square

= x²

= 200cm²

Area of shaded region

= 3.14(10²) -200

= 3.14(100) -200

= 314 -200

= 114 cm²

Answer:

16 pts

Step-by-step explanation:

1qt = 2pts

Answer: 96 cm

Step-by-step explanation:

The perimeter is the combined sum of the sides.

So 18 + 22 + 3 + 8 + 6 + 15 = 72

To find the 2 missing sides we use the information we already have.

On the top, we can see 18 is overall the largest line from the missing side.

So we'll need to subtract something from 18.

15 - 8 = 7 ( Inferencing )

18 - 7 = 11 ( length of the top missing side )

22 - 9 = 13

11 + 13 + 72 = 96 cm

Answer:  The perimeter is 85 cm

Step-by-step explanation:

To find the perimeter you will need to add the distance around the shape.

But there seem to be one missing side .

To find that missing side we will have to add 3cm and 6 cm then subtract it from 22.

3 + 6 = 9

22 - 9 =  13

Now add the distance around the shape plus the 13.

22 + 15 + 6 + 8 + 13 + 3 + 18 =  85

Answer:

3,4,5

Step-by-step explanation:

Integers means whole number

< and > means that the integers can't be the same as the number before.

Hope that helps!!

Answer:

$112,710

Step-by-step explanation:

so first we have to find what is 15% of 86700

so 15/100×86700=$13005

so it is written that 86700 is in 2012 means 2010 it will be

2 times more which means 30% that means just have to do is multiply it two times which makes it $26010

so $86700+$26010=$112710

hope it helps you

Answer: 16⁹ and False.

Step-by-step explanation:

Answer:

B ,false

Step-by-step explanation:

Answer:

1) a

2) c

3) a

Step-by-step explanation:

1) Subsitute

2.14x - 42.9 = ?

2.14(22.4) - 42.9 = ?

47.936 - 42.9 = ?

= 5.036

2) Factor out

6y^2 + 27y

both have 3 and y in common so ...

3y(2y + 9)  

3) Distribute

12m(m - 3n)

12m * m = 12m^2

12m * -3n = -36mn     the only reason -3 is NOT a positive is b/c it has subtraction sign b4 the number

put it in order:

12m^2 - 36mn

Answer:

96inches

Answer:

24

Step-by-step explanation:

6 ÷ 15 = 0.4

X to Y = 20 × 0.4 = 8

Y to Z = 25 × 0.4 = 10

Perimeter: a + b + c

6 + 8 + 10 = 24

Even I am surprised by what I wrote. Hopefully, it is right and helps you ^-^ Please comment if you have any questions.

Answer:

See explanation

Step-by-step explanation:

The standard compound interest formula is [tex]A = P(1+\frac{r}{n})^{nt}[/tex] where:

P is the principal amount

r is the interest rate (typically as a percentage)

t is the time

n is the times compounded per unit of time

So,

1)  [tex]A = 50000(1+\frac{0.03}{12})^{(12)(6)} =59847.42[/tex]

2) [tex]A = 43000(1+\frac{0.05}{1})^{(1)(3)} =49777.88[/tex]

3) [tex]A = 65000(1+\frac{0.06}{4})^{(4)(12)} =132826.08[/tex]

You should check my answers though, I may have mixed up some terms.

Answer:

Step-by-step explanation:

X > 3/7

We know that the student sleeps in at least 3 days, but we don't know what the exact number is, we use an inequality where X is greater than or equal to 3 out of the 7 days.
