Answer: A, 12
Step-by-step explanation:
The line in the middle is a midsegment, making the two triangles similar by a ratio of two. So, dividing 60 by five will give you twelve
Answer:
There is a 33.3% chance you will pull a red marble after pulling a blue one.
Step-by-step explanation:
There are a total of 10 marbles in the sack. A blue marble is removed from the bag without being replaced, leaving 9 in the sack. 3 of the marbles left are red. To find the probability of pulling a red marble, we divide the number of red marbles by the number of total marbles.
3/9 = 1/3 = 0.333 = 33.3%
It has to be at least 3cm to make it a right triangle
The inequality that Matt could solve to find out how many more miles he can run if he keeps his current pace is less than 6 miles.
<h3>How to express the inequality?</h3>
It should be noted an inequality is used to show the expressions that are not equal.
In this case, Matthew wants his run today to take no more than 90 minutes and he already has run 30 minutes at a pace of 10 minutes per mile.
Therefore, the appropriate inequality will be;
Let miles = m
m <= 90/10 - 30/10
m <= 9 - 3
m <= 6
He has about 6 miles more.

The surface area would be :
A = 4 (1/2 x b x h) + (l x b)
A = 4 ( 1/2 x 42 x 35) + (42 x 42)
A = 4704 cm squared
