Answer:
87.48
Step-by-step explanation:
First find the area of the square
12^2=144
find area of the 2 circles
9*3.14
but theres 2
18*3.14=56.52
144-56.52=87.48
One centiliter is equal to ten milliliters so Jason is taking 20 ml of medicine, You multiply 2cl X 10ml = 20ml
Answer:
32 people came in blue cars and 6 people came in red cars
Step-by-step explanation:
Technically, all 48 people came in red or blue cars, but I'm assuming that's not what the question is asking.
To find how many people came in blue cars, we do 2/3*48 which is equal to 32 people.
To find how many people came in red cars, we do 1/8*48 which is equal to 6 people.
Answer:
X=23
Step-by-step explanation:
You should know that a triangle =180 degrees
Add all your angles together and =180
66+2x+3+3x-4=180
add similar terms
5x+65=180
Move your 65 to the other side
5x=115
x=23
(Optional)
to check if your answer is right substitute your x and add all angles together you should get 180 degrees.
7.5cm
lets take point K represent lenght from M to perimeter of circle.
r is radius
KM= r-OM= r-4.5cm
now lets draw line from O to A (OA)
we get triangle.
hypotenuse is OA and it equals r(radius)
ab=12 cm. so another side of the triangle (AM) is 12/2=6cm. and the last side of the triangle is 4.5(OM)
use pythaghorean theorem
squares of sides added = square of hypotenuse
20.25+36=r^2(our hypotenuse is radius)
56.25=r^2
r=√56.25=7.5cm
