PLEASE HELP ASAP! WILL GIVE BRAINLIEST! The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answers
Answer:
Solution:- In the given figure
Side of square= 10 cm
area of square = side x side m= 10 x 10 = 100 sq cm
Now , diameter of semi circle AOD = 2r = 10cm
⇒ radius of semi circle AOD = 5 cm
∴ area of AOD =
similarly Area of semicircle BOC =
Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]
=
Total area of white portion in the given figure=
∴Area of Shaded portion = area of square - area of total white portion
=
So the area of shaded portion is
Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)
So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm

jordan has 785$ in his savings account. he withdraws 15% of money to pay for school clothes. which is the best estimaye for the amount of money jordan withdraws?
Answers
Answer:
52%
Step-by-step explanation:
you got to divide 15 by 785. First 15 goes into 78 5 times which is 75. Then subtract 78 by 75 which is 3. Then bring down the 5 which makes 35 and then 15 goes into 35 two times which is 30 subtract 35 by 30 which is 5 bring up the 5 into a fraction and the ansewer in percentage is 52%.
if the breadth of rectangle in one fourth of its length and perimeter is 60 cm ,find the length and breadth of rectangle
Answers
Answer:
Breadth/width = 1.936cm, length = 7.746cm
Step-by-step explanation:
Perimeter of a rectangle would be [tex]2L*2W=60cm[/tex] in this case. Breadth is width.
But we can rewrite this equation given that the width is 1/4 the length. This means 4 of the widths would equal one length.
[tex]W=\frac{1}{4}L[/tex]
[tex]L=4W[/tex]
We can substitute L with the 4W
[tex]2(4W)*2(W)=60cm[/tex]
Now we can just solve for the width W.
[tex]8W*2W=60\\16W^2=60\\W^2=\frac{15}{4} \\W=\sqrt{\frac{15}{4} } \\W=\frac{\sqrt{15} }{2}=1.936cm[/tex]
We now know the width is about 1.936cm
We can find the length given our formula before of [tex]L=4W[/tex]
[tex]L=4(\sqrt{\frac{15}{2} } )=2\sqrt{15} =7.746cm[/tex]
So the breadth/width is 1.936cm and the length is 7.746cm.

Which number is the greatest?
A the square root of 125
B the whats root of 30
Answers
Answer:
B) √(30)
Step-by-step explanation:
A: The cube root of 125 is 5 because 5^3, or 5 × 5 × 5, equals 125.
B: The square root of 30 is between the numbers 5 and 6, meaning 30 is between 25 and 36. The square root of 30 is about half-way in between 5 and 6, so we can say √(3) ≈ 5.5
Now, when we compared 5.5 and 5, 5.5 is obviously greater. Therefore, the correct answer is B √(30).

Answers
So, 220,000 gallons of water is used to produce 4,000 pounds of steel.
4,000 pounds = 220,000 gallons
Divide both sides by 4,000 to get:
1 pound = 55 gallons.

There's a roughly linear relationship between the length of someone's femur (the long
leg-bone in your thigh) and their expected height. Within a certain population, this
relationship can be expressed using the formula h = 63.4 +2.41f, where h
represents the expected height in centimeters and f represents the length of the
femur in centimeters. What is the meaning of the f-value when h=123?
Answers
Answer:
24.73
Step-by-step explanation:
h=63.4+2.41f
h=123
123=63.4+2.41f
59.6=2.41f
24.73=f
If the value of h is 123. Then the length of the femur will be 24.73 centimeters.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
h = 63.4 + 2.41 f
Where h represents the expected height in centimeters and f represents the length of the femur in centimeters.
If the value of h is 123. Then the f-value is given as,
123 = 63.4 + 2.41 f
2.41 f = 59.60
f = 24.73 cm
Assuming that the worth of h is 123. Then, at that point, the length of the femur will be 24.73 centimeters.

Step-by-step explanation:
"Given ABC is an isosceles triangle and DBE is an equilateral triangle. we have to find each missing measure.
In triangle ABC,
∠1=∠9 (∵isosceles triangle)
⇒ 4x+3=9x-47
⇒ 9x-4x=3+47 ⇒ 5x=50 ⇒ x=10
Hence, ∠9=∠1=(4x+3)°=4(10)+3=43°
Also, given ΔBDE is an equilateral triangle, and all angle of equilateral triangle are equal.
∴ ∠4+∠5+∠6=180°
⇒ ∠4+∠4+∠4=180° ⇒ 3∠4 = 180° ⇒ ∠4 = 60°
∴ ∠4=∠5=∠6=60°
By exterior angle property, ∠3=∠5+∠6=60°+60°=120°
∠8=∠5+∠4=60°+60°=120°
In ΔABD, ∠1+∠2+∠3=180°
⇒ 43°+120°+∠2=180°⇒ ∠2 = 17°
In ΔABD, ∠9+∠8+∠7=180°
⇒ 43°+120°+∠7=180°⇒ ∠7= 17°"
