Answer:
Step-by-step explanation:
Diameter = 18 m
D= 2*r
r = d/2
r =18/2
r = 9
Circumference = 2 * pi * r
C = 2 * 3.14 * 9
C = 56.52
Area = pi r^2
Area = 3.14 * 9^2
Area = 3.14 * 81
Area = 254.34
Answer:
Radius=9
Circumference= 56.52 or 56.52
Area= I not sure
Step-by-step explanation:
Radius= 18 divided by 2 equals 9
Circumference= 18 times 3.14

Two number cubes are rolled.
What is the probability that the first lands on an odd number and the second lands on an even number?
Enter you answer, as a fraction in simplified form, in the box.
Answers
Answer:
1/2
Step-by-step explanation:
if both cubes are 6 sided. Then for the first one the probability is 3/6. second is also 3/6. but we are looking for the probability of this outcome. we can add all of the sides to get 12. then we have 3 even numbers and 3 odd numbers. which added together is 6. we bow have 6/12, which is 1/2 simplified

Answer: The speed of the car is 45.3 miles per hour.
Step-by-Step Explanation: Let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3
Answer:
The car was traveling at an average speed of 45.3 miles per hour.
Step-by-step explanation:
We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.
We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):
30.2/40=x/60
We then cross multiply:
30.2x60=40(x)
1,812=40(x)
Divide each side by 40
1,812/40 = x
x=45.3

Step-by-step explanation:
6(x +4) = 6(x + 7) - 3x
6x + 24 = 6x + 42 - 3x
6x - 6x + 3x = 42 - 24
3x = 18
x = 18/3
x = 6

Step-by-step explanation:

hope it helps please like
Answers: 2x - 6 = 20 & x = 13
Explanation: The x in this equation is the temperature 5 hours ago. In the word problem, 20 degrees is the x temperature multiplied by 2 (since it says “twice the temperature”) and subtracted by 6 (since it says “6 degrees less). Therefore, the equation would be the x changing (due to the multiplying of 2 and subtraction of 6) that equal 20. When solving, first check to see if there are any like terms (None in this problem). Next, isolate the variable. Here, you add the opposite of 6 to both sides (-6 + 6 and 20 + 20). This makes it 2x = 26. Now divide by the coefficient (2x / 2 and 26 / 2). This will be x = 13. Hope this helped!

A dilation with a scale factor of 1/3 is a reduction. A dilation with a scale factor of 2 is a reduction . which is true and which is false
Answers
Answer:
True: A dilation with a scale factor of 1/3 is a reduction.
False: A dilation with a scale factor of 2 is a reduction.
Step-by-step explanation:
A dilation with a scale factor between 0 and 1 is a reduction because the image will decrease in size.
On the other hand, a dilation with a scale factor greater than 1 is an enlargement, where the image increases in size.
So, the statement that a dilation with a 1/3 scale factor is a reduction is true.
The other statement is false, which says a dilation with a scale factor of 2 is a reduction.
