Answer:
3/20
Step-by-step explanation:
From the above question,
The total number of balls = 20
Number of red balls = 6
Number of yellow balls = 10
Probability of picking a red ball with replacement = P(red) = 6/20
Probability of picking a yellow ball with replacement = P(yellow) = 10/20
The probability of picking a red golf ball, replacing it, and then picking a yellow golf ball is calculated as
P(red) × P( yellow)
= 6/20 × 10/20
= 3/10 × 1/2
= 3/20
Answer:
pyramid with square base.
Step-by-step explanation:
We have been given some description about a simple solid which looks like a square from above, a triangle from the front, and a triangle from the side.
Now we need to figure out which solid has above properties.
The answer will be pyramid with square base. Because side walls of pyramid are always in same shape.
So you could do it by 180=35+90+c
Then you would add 35 and 90 to get 125
Then you would subtract 125 from both sides
That would leave you with 55=c
So then the measure of angle C would be 55
C=55
Answer:
The length of the third side of the triangle is 30.
Step-by-step explanation:
Here is the formula for the Pythagorean Theorem:
The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!
We need to multiply 40 times 40 and 50 times 50.
40 times 40, or 40 squared, equals to 1600.
50 times 50, or 50 squared, equals to 2500.
Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.
Answer:
see below
Step-by-step explanation:
9 is the difference of a number n and 7.
Let's break this down.
"is" represents the equal sign.
"the difference" represents subtraction.
9 = n - 7
Now let's solve the equation.
9 = n - 7
Add 7 to both sides.
16 = n
Hope this helps!
