Calculate the area of the shaded part to 1dp​

Calculate The Area Of The Shaded Part To 1dp

Answers

Answer 1

Answer:

To find the area of the shaded region

A = Area of circle - Area of square

12cm is the diagonal of the square and diameter of the circle.

To find the side of the square,

d = √2 * s

12cm = √2 * s

s = 8.49cm

Area of square = L²

As = (8.49)²

As = 72.1cm²

Area of circle = πr²

r = 6cm

Ac = (π*36)cm²

Ac = 113.1cm²

A = Ac - As

A = 113.1cm² - 72.1cm²

A = 41cm²

The area of the shaded region is 41cm².

Answer 2

Answer: I can't tell from the photo which is the shaded part. I'll answer on the assumption it is either the square in the circle, or the 4 areas defined by the semicircles outside the square, but inside the circle.

Step-by-step explanation: Note the caveat above.

Circle Area = pi*r^2 or (3.14)*(6cm)^2 = 113.1 cm^2

Area of the square: The 12cm line forms an hypotenuse with either side. The sides are all equal, so if x is 1 side, we can say the area is x^2. We also know tha x^2 + x^2 = 12

x^2 = 6 cm^2 (the area of the square)

The two possible answers:

1) Shaded portion is the square: 6 cm^2

2) Shaded area means the 4 semicircles outside the square but within the circle: 113.1 cm^2 - 6 cm^2 = 107.1 cm^2

Gary had a 40% discount for car speakers. The sale price of the speakers was $96.25. What was the original price of the speakers? Round to the nearest cent.

Answers

Answer:

Step-by-step explanation:

If the price after the discount is subtracted is $96.25 then this is what you do

u times 0.40 x 96.25 which is 38.5 so since you are wanting to know what the price was before the discount you would add 38.5 to 96.25 and when you do that your answer is 134.75

but if you are just trying to get the discount from 96.25 you subtract 38.5 from 96.25

I need help with these 2 problems I cant figure out.

I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.

2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)

Next, I add 20 on both sides.

2x + 90 + 3x = 200º

I combine like terms (2x and 3x)

5x + 90 = 200º

I subtract 90 from both sides.

5x = 110º

Divide 110 by 5 to get x.

x = 22

======

For problem two, I label all the angles I know.

49º + 80º + r = 180º

I add 80 and 49.

129º + r = 180º

I subtract 180 and 129 and get 51º, which is your angle for R.

For angle X, you know that angle R plus angle X equals half of a circle, which is 180º

We know from before that 129º is 180º without R, so X is 129º

I hope this helps! Let me know if I'm wrong!

y is inversely proportional to the squre of X.given that Y=2 when X=6, find the calue of y when x=2

Answers

Answer:

y = 2/9

Step-by-step explanation:

y=x²

y=kx²

2= k(6)²

2= 36k

k= 1/18

The connecting formula is

y= 1/18x²

when y=? , x=2

therefore,

y= 1/18x²

y= 1/18(2)²

y= 1/18(4)

y= 2/9

Answer:

y = 18 when x = 2

Step-by-step explanation:

y ∝ x^2

y = k/x^2

Substituting 'y=2' and 'x=6' to get the value of k:

2 = k/6^2

2 = k/36

k = 36*2

= 72

Hence,

y = 72/x^2

Substituting 'x=2' to get the y-value:

y = 72/2^2

= 72/4

= 18

Hence,

when x =2, y = 18

If Sarah sold 20 bags of dog treats for $3.25 each, how much money did she earn? You must show your work to earn full credit.

Answers

Answer:

$65

Step-by-step explanation:

20 bags of dog treats multiplied by 3.25 = $65.00

Sarah made 65 dollars.

Answer:

Sarah earned $65.

Step-by-step explanation:

Create an equation.

20 representing the bags she has sold, 3.25 representing the value of each bag. If Sarah sold 20 bags of dog treats, with each of them being worth 3.25, then 20(3.25) = 65, meaning Sarah earned $65.

Answer:

J= 16.857°

K= 88 .4°

L=74.7°

Step-by-step explanation:

let x represent the angle of J

x° +(4x+21)° +(2x+41)° =180°

x + 4x + 21 + 2x + 41= 180° ( sum of angles in a triangle)

Collect like terms

x + 4x + 2x = 180 - 21 - 41

7x = 180

x =180/7

x=16.857

Therefore,

J = 16.857°

K=4x+21

=4(16.857)+21

= 67.4+21

=88.4°

L=2x +41

=2(16.857)+41

=33.7+41

= 74.7°

Sum of angles in the triangle =

16.857+88.4+74.7=179.9 approximately 180°

Answer:

X=5

Step-by-step explanation:

3x+1=16

move the 1 over to the 16 so it is 16 - 1 = 15

3x=15

Move the 3 over to where the 15 is in order to get x by itself

3/3 = x

3/15 = 5

so X should = 5

The figure shows line RS parallel to line UV. The lines are intersected by 2 transversals.
If the measure of angle STV is 108 degrees and the measure of angle RST is 74 degrees, the measure of angle TVU is [blank1] degrees. :|

Answers

Answer:

Step-by-step explanation:

The measure of angle TVU is 74 degrees.

What is alternate interior angles?

The alternate interior angles are the angles that are formed inside the two parallel lines, when it is intersected by a transversal, and are equal to its alternate pairs.

What is linear pair angles?

Linear pair of angles are formed when two lines intersect each other at a single point.

According to the given question.

m ∠STV = 108 degrees

And,

m ∠RST = 74 degrees

Since, ∠RTS and ∠STV are linear pair of angles.

Therefore,

m ∠RTS + m ∠STV = 180

⇒ m ∠RTS + 108 = 180

⇒ m ∠RTS = 180 - 108

⇒ m ∠RTS = 72 degrees

Now, in ΔRTS we have

m ∠RTS + m ∠TSR + m ∠SRT = 180  (sum of the angles of a triangle is 180 degrees)

⇒ 72 + 74 + m ∠SRT = 180

⇒ m ∠SRT = 180 -146

⇒ m ∠SRT =  34 degrees

Here, ∠SRT and ∠TVU are alternate interior angles.

Therefore,

m ∠SRT = m ∠TVU

⇒ m ∠TVU = 74 degrees.

Hence, the measure of angle TVU is 74 degrees.
