Step-by-step explanation:
Find the radius: 19 ÷ 2 = 9.5
4/3 x 22/7 x 9.5 x 9.5 x 9.5 = 3592
3592/3 =
1197.3 (Rounded to 1 decimal place)
Answer: 1197.3cm3
(I have never done area or perimeter of sphere before, but I did for other shapes. This is just my attempt using the methods I did for other shapes by the way)
There are 11 days until Richards's concert.
Susie's concert is 7 days after Richard's.
so Susie's concert: 11+7=18
answer
D. 11+7=18
Answer:
Yes, They are similar by SSS PMK similar to LMQ.
Step-by-step explanation:
Similar triangles corresponding side lengths are in a proportion.
KM corresponds with MQ
PM corresponds with LM.
Set up this proportion.
Cross multiply
So the triangles ARE Similar.
- PM corresponds with LM
- KM corresponds with MQ
- PK corresponds with LQ
- So PMK is similar to LMQ
Answer:
315
Step-by-step explanation:
each one adds 15.
300 + 15 = 315
Start by doing a subtraction of 6 to both sides so that the equation becomes -2x^2 + 7x + 1 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √((7)^2 - 4(-2)(1)) ] / ( 2(-2) )
x = [-7 ± √(49 - (-8) ) ] / ( -4 )
x = [-7 ± √(57) ] / ( -4)
x = [-7 ± sqrt(57) ] / ( -4 )
x = 7/4 ± -sqrt(57)/4
The answers are 7/4 + sqrt(57)/4 and 7/4 - sqrt(57)/4.
