Is this correct?? Please dont mine the little notes I took when solving it..
A= 12, base= 16
Area= (1/2)(12)(16) = 96
384+96 =480
Semi Circle should be something like =(1/2) pir^2
diameter= hypotenuse= sqrt(12^2 +16^2) = 20
radius= r= d/2= 20/2
Semi Circle= (1/2) pi 10^2= 50pi= 157.0796327
Total = 480+157.0796327=637.0796327. Rounding to the nearest hundred would give me 637.08??
Answer and Step-by-step explanation:
Yes, all of your calculations are correct!!
The area of one rectangle is 192, and since there are 2 rectangles, we multiply 192 by 2, which results in 384.
The area of a triangle is [tex]A = \frac{(Height)(Base)}{2}[/tex], which you got to be 96.
The Semi Circle would have half of the area of a circle, so you are correct when you multiply the equation by [tex]\frac{1}{2}[/tex].
To find that diameter, we need to use the Pythagorean Theorem.
[tex]12^{2} + 16^{2} = d^{2} \\\\144 + 256 = d^{2} \\\\400 = d^2\\\\d = 20[/tex]
So the diameter is 20, and the radius is 10 (20 divided by 2 = radius).
Plug that into the equation, and you get the answer to be [tex]50\pi[/tex], or 157.0796327.
157.0796327 + 384 + 96 = 637.08 (rounded to the nearest hundredth).
Good job!

Find the value of a. 19 km 19 km Perimeter = 57 kilometers
Answer:
19km
Step-by-step explanation:
The formula for the perimeter of a triangle is: S+S+S.
So;
19km+19km+a=57km
a=57km-19km-19km
=19km
Solve the equation
2.9=7.1 + y
Answer:
y=-4.2
Step-by-step explanation:
2.9=7.1+y
2.9-7.1=7.1-7.1 +y
-4.2=y or y= -4.2
y = -4.2
If you substitute that value for y into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. HOPE THAT HELPS!
solve the triangle give the measure of angle G
Answer:
G = 46 degrees
Step-by-step explanation:
Here, we want to find the measure of angle G
Mathematically, as we can see, what we have is a right triangle
For a right triangle , the sum of angles is 90 degrees
Thus, if we add the two internal angles, we get 90 degrees
Hence;
44 + G = 90
G = 90-44
G = 46 degrees

Answer:
C.
Step-by-step explanation:
Replace y with each value.
If y is 2 then the answer would be -2
If y is 4 then the answer would be -1
If y is 8:
8/2 = 4
4-3 = 1

Kelly had a part-time job last year. She paid the state $234 in income tax. The state income tax rate is 5.2%. How much did Kelly earn?
Answer:
$4500
Step-by-step explanation:
Find how much she earned by dividing 234 by 0.052
234/0.052
= 4500
So, she earned $4500
Answer: see below
Step-by-step explanation:
Divide 234 by 5.2 to get one percent of her earnings, $45.
Multiply 45 by 100 to get 100% of her earnings, $4,500
If it asking for the gross earnings, leave it at $4,500
If it is asking for net earnings, subtract 234 from 4500 to get $4,266

Please help I’ll mark brainliest
Answer:
y= x-3
Step-by-step explanation:
use the slope formula which is y= m(slope)x + b(y intercept)
The slope is one, so you can just leave it as x, and the y intercept is -3 so you can plus that into the b.

find the area of the figure. round your answer to the nearest hundredth
Answer: 84.14
Step-by-step explanation:
Area of the rectangle is L*W=B*H
14*5=70
To find the area of the half circle we must use the formula pi r^2/2
r=radius
and the radius is 6 because we add 4 and 4 and need to get to 14
because the line below it is 14 and it is a rectangle so the lengths are the same.
Diameter=6
So radius =3
pi (3)^2/2=
9/2 pi + 70=
84.14
Answer: 84.13
lmk if this is wrong
Step-by-step explanation:
Area of the rectangle:
5(14)=70
Area of the half circle:
Formula: πr^2
Substitute: 3.14(3)^2
Solve: 3.14(9)
3.14(9)=28.26
Divide the area by 2 since it's a half circle
28.26/2=14.13
Add the area of the rectangle and half circle
70+14.13=84.13
