Write a couple sentences to explain how you would find the area of the shaded region:
Answer:
I would find the area of the circle and then find the area of the shape in the middle and then minus that from the area of the whole circle
Answer:
Step-by-step explanation:
1. Find the area of the circle. Area_c = pi * r^2
2.Find the area of the pentagon in terms of the radius Area_P =
3 sqrt(3) r^2 / 2
The answer you want is Area_shade = Area_c - area_P
Area = pi * r^2 - 3 sqrt(3)r^2/2
Area = r^2 (pi - 3 sqrt(3)/2)
Find the midpoint
(12,15) and (-8, -22)
When muiltplying two exponents, If the base numbers are DIFFERENT can u add the two exponents?
∠K and ∠L are complementary angles. If m∠K = 3x + 3 and m∠L = 10x – 4, find the measures of both angles.
Answer:
∠K =24
∠L =66
Step-by-step explanation:
first you need to find X in order to solve.
since they are Complementary they add together to equal 90 degrees
so we can set them equal to 90
13x-1=90
13x=91
x=7
now we can plug them in!
---
∠K = 3(7)+3 = 24
∠L =10(7)-4=66
4 less than 2 times the number x
Answer:
2x-4
Step-by-step explanation:
1) Since it says 2 times the number x, it is 2x
2) Then, it says 4 less than 28
3) The equation/answer would be 2x-4
Answer:
The answer is 2x-4
-13=4x+3
Help please
Hey there! I'm happy to help!
Let's flip the equation so x is on the left. We want to isolate x to see what it equals.
4x+3=-13
We subtract 3 from both sides.
4x=-16
We divide both sides by 4.
x=-4.
Have a wonderful day! :D
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 4}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ - 13 = 4x + 3}[/tex]
Swap the sides of the equation
[tex] \longrightarrow{ \sf{4x + 3 = - 13}}[/tex]
Move 3 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{4x = - 13 - 3}}[/tex]
The negative integers are always added but posses the negative ( - ) sign
[tex] \longrightarrow{ \sf{4x = - 16}}[/tex]
Divide both sides by 4
[tex] \longrightarrow{ \sf{ \frac{4x}{4} = \frac{ - 16}{4}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{x = - 4}}[/tex]
Hope I helped!
Best regards! :D

Step-by-step explanation:
[tex] \sf \implies \dfrac{a - b}{b} = \dfrac{3}{7} \\ \\ \sf \implies \frac{a}{b} - \frac{b}{b} = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 = \frac{3}{7} \\ \\ \sf \implies \frac{a}{b} - 1 + 1 = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + 1 \\ \\ \sf \implies \frac{a}{b} = \frac{3}{7} + \frac{7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{3 + 7}{7} \\ \\ \sf \implies \frac{a}{b} = \frac{10}{7} [/tex]

In triangle ABC, the size of angle B is 5 times the size of angle A, and the size of angle C is 11 degrees less than 4 times the size of angle A.
Find the size of the angles.
Answer:
A = 19.1°
B = 95.5°
C = 65.4°
Step-by-step explanation:
B = 5A
C = 4A-11
We know that a triangle has a total of 180° so:
180 = A + B + C
Which can be written as:
180 = A + (5A) + (4A - 11)
180 = 10A - 11
10A = 191
A = 19.1°
With A, we can work out B and C:
B = 5(19.1)
B = 95.5°
C = 4(19.1) - 11
C = 76.4 - 11
C = 65.4°

What is the slope of the line ?
Answer:
The slope of a line characterizes the direction of a line.
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. also You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

I WILL NAME BRAINLIEST FOR WHOEVER CAN WRITE THE ANSWER! I WILL NOT GIVE IT ANYONE WHO JUST POINTS! What is the area of the figure below?
Answer:
[tex]48.5cm^{2}[/tex]
Step-by-step explanation:
This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with [tex]7*8=56[/tex] and subtract the triangle.
Area of missing triangle = [tex]\frac{1}{2} *b*h[/tex] (b is the base and h is the height)
Base = [tex]8-3=5[/tex]
Height = [tex]7-4=3[/tex]
Area of missing triangle = [tex]\frac{1}{2} *5*3=7.5[/tex]
Area of the figure: [tex]56-7.5=48.5[/tex]
--------------------------------------------------------------------------
Alternatively, you can find the area of each individual shape and add them all up.
Area of the rectangle: [tex]8*4=32[/tex]
Area of square: [tex](7-4)*3=9[/tex]
Area of triangle: [tex]\frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5[/tex]
Total Area: [tex]32+9+7.5=48.5[/tex]
Answer:
49.2
Step-by-step explanation:
I first found the area (length x Width) of the rectangle which is 8x4= 32
Then I subtracted 7cm and 4cm to find the width of the square which is 3cm
To find the area of the square multiple 3x3= 9
Then to find the area of the triangle I subtracted 8cm and 3cm to get the length of the triangle which is 5cm
You already know the width of the triangle (3cm) so you multiply 5cm x 3cm to get 15, but snice its a triangle you’re going to divide 15 by 2 = 7.2
Lastly your going to add up all those numbers :
32+9+7.2 = 49.2
So the area of the triangle is 49.2
