pls help for #9! whats the area of the shaded region ?
Answer:
21.5
Step-by-step explanation:
square is 10x10 = 100
circle is A=πr2=π·5²≈78.54
100-78.54 = 21.46 = 21.5
Answer:
21.5 sq cm
Step-by-step explanation:
Area of Square:
A= LXW= 10x10= 100 sq cm
Area of Circle=
A=πr²
Radius= D/2= 10/2= 5 cm
A=3.14(5²)
A=3.14(25)= 78.5 sq cm
Shaded Region= 100-78.5= 21.5
The area of the shaded region is 21.5 sq cm.

Half of R is shown as 20 degrees, so the other half of r is also 20 degrees.
A tangent line forms a right angle, so the tangent at P is 90 degrees.
X would be 180 - 90 - 20 = 70 degrees.
X = 70 degrees.

Answer:
Area = 220.8 units²
Step-by-step explanation:
Since, given regular hexagon is made up of 6 congruent triangles joined together.
Area of the given regular hexagon = 6(Area of ΔAOB)
Area of ΔAOB = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(AB)(OC)[/tex]
= [tex]\frac{1}{2}(9.2)(8)[/tex]
= 36.8 unit²
Therefore, area of regular hexagon = 6(36.8)
= 220.8 units²
What two things make a graph proportional?
Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each.
Step-by-step explanation:
here's your solution
=> total money received by them = $1600
=> the given ratio are 7:5:4
=> let the ratio be X ,now
=> Maria = 7X
=> Carolina = 5X
=> Pedro = 4X
=> we know whole money = $1600
=> so, adding all
=>. 7x + 5x + 4x = $1600
=> 16x = $1600
=> x= $1600/16
=>. x = $100
now Maria = 7*100 = $700
Carolina = 5*100 = $500
Pedro = 4*100 = $400

There are 2 pigs, 1 cat, 3 goats, and 4 cows at the state fair. As people enter the barn area they are randomly given one animal to pet. What is the probability that a person will pet a goat? Write your answer as a fraction, decimal, and percent.
PLS ANSWER QUICK and pls dont answer with a website answer with the answer
Fraction:
Decimal:
Percent:
Answer:
3/10
Step-by-step explanation:
Probability will be the number of goats, since goats is what you're looking for, over the number of total animals. So that gives 3/10.
To get that as a decimal, divide 3 by 10. Then take your decimal and multiply it by 100 to give the percent.
Find the volume of the pyramid, given its slant height. Round them to the nearest tenth please.
Can you help me? I tried but I did not understand and thank you
9514 1404 393
Answer:
4. 1.3 cm³
5. 621.2 mm³
6. 116.5 m³
Step-by-step explanation:
The height to the peak of the pyramid is one side of the right triangle that has its hypotenuse equal to the slant height, and one leg equal to half the base side length. The Pythagorean theorem is used to find the height from the slant height (s) and the base length (b):
h = √(s² -(b/2)²)
The volume is found from the formula ...
V = (1/3)b²h
where b is the base length and h is the height found using the previous formula.

∠A and ∠ B ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ ∠A=(4x−16) ∘ and m ∠ B = ( 8 x + 4 ) ∘ ∠B=(8x+4) ∘ , then find the measure of ∠ A ∠A.
Answer:
∠ A = 48°
Step-by-step explanation:
Supplementary angles are those angles that measure up to 180 degrees.
∠A and ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ and m ∠ B = ( 8 x + 4 ) ∘,then find the measure of ∠ A
Step 1
∠A + ∠B = 180°
(4x−16)° + (8x+4)° = 180
4x - 16 + 8x + 4 = 180
12x -12 = 180
12x = 180 + 12
12x = 192
x = 192/12
x = 16
Step 2
To find the measure of ∠ A
∠ A = 4x - 16
= 4 × 16 - 16
= 64 - 16
= 48°
Therefore,
∠ A = 48°
[Help asap, will mark brainliest] Find the distance between the following pairs of points on the coordinate plane. Round to the nearest tenth if necessary.
The distance between point A and point D = units
Answer:
8.06 units = AD
(just write sq rt 65 = 8.062 ) then write or try sq rt of 65 to 3 sf = nearest tenth 8.06 tenth units rounded.
Step-by-step explanation:
AE = 7
ED = 4
We use Pythagoras Theorem as it is a right angle as AE^2 + ED^2 = AD^2
7^2 + 4^2 = AD^2
49 + 16 = 65 sq rt
sq rt 65 = AD^2 = 8.062^2
AD = 8.062 units
Point E (-2, -5) is dilated from the origin by scale factor of r = 3/2. What are the coordinates of point E.
Answer:
The new coordinates of E are (-3,-15/2).
Step-by-step explanation:
Here we just need to multiply each element of this point by r.
So we have:
[tex]E_{new}(-2*(\frac{3}{2}),-5*(\frac{3}{2}))[/tex]
[tex]E_{new}(-3,-\frac{15}{2})[/tex]
Therefore, the new coordinates of E are (-3,-15/2).
I hope it helps you!

Step-by-step explanation:
Hope this helps :)
Answer:
x = 3, y = 30
Step-by-step explanation:
Since the 3 sides are congruent then the triangle is equilateral.
The 3 angles are congruent and equal tp 60°
Evaluate each of the angles to 60 and solve for x and y , that is
25x - 15 = 60 ( add 15 to both sides )
25x = 75 ( divide both sides by 25 )
x = 3
and
2y = 60 ( divide both sides by 2 )
y = 30
solve graphically please send me by solving and clicking photo plzzzz
Answer:
Subtract 5x from both sides of the equation.
7y=1−5x
x+4y=−5
Divide each term by 7 and simplify.
y=17−5x/7
x+4y=−5
Subtract x from both sides of the equation.
y=1/7−5x/7
4y=−5−x
y=1/7−5x/7
Divide each term by 4 and simplify.
y=1/7−5x/7
y=−5/4−x/4
y=1/7−5x/7
