Answer 2

Answer:

Final answer:

To subtract 2 hours, 20 minutes from 4 hours, 10 minutes, subtract the hours and minutes separately. The answer is 1 hour, 50 minutes.

Explanation:

To subtract 2 hours, 20 minutes from 4 hours, 10 minutes, you need to subtract the hours and the minutes separately.

Start by subtracting the hours: 4 hours - 2 hours = 2 hours.
Then subtract the minutes: 10 minutes - 20 minutes = -10 minutes.
Since we have a negative number for the minutes, we need to borrow 1 hour from the hours, which gives us: 2 hours - 1 hour = 1 hour.
Finally, add the remaining minutes: 60 minutes - 10 minutes = 50 minutes.

Therefore, the answer is 1 hour, 50 minutes.

How many 5 digit numbers less than 47999 can be formed from the digits {1,2,3,4,5,6,7,8}, if repetition of the digits is allowed?

Answers

To determine the number of 5-digit numbers less than 47999 that can be formed from the given digits (1, 2, 3, 4, 5, 6, 7, 8), with repetition allowed, we can analyze each digit's possibilities.

For the first digit:
- The first digit can be any of the given digits (1, 2, 3, 4, 5, 6, 7, 8) except for 0, since we want the number to be less than 47999. So there are 8 options for the first digit.

For the remaining four digits:
- Each of these digits can be any of the given digits (0, 1, 2, 3, 4, 5, 6, 7, 8), since repetition is allowed. So there are 9 options for each of the remaining four digits.

Therefore, the total number of 5-digit numbers that can be formed is:
8 * 9 * 9 * 9 * 9 = 52,488

84 of %300. i somehow got 24 but the answer was something like 252, i dont really get how. can you help?

Answers

Answer:

252

Step-by-step explanation:

Of means multiply

84 % * 300

Change to decimal form

.84 * 300

252

Step-by-step explanation:

You need to set up a proportion. Percents always over percents, so our first fraction would be $(84)/(100)$ , which just means that out of 100%, we are given 84. We need to find a variable to solve for: x. We need to find the number that is 84% of 300, which means that 300 is 100%. Knowing this, it would be in the denominator, since both 100 and 300 are 100% of something. This would give us the fraction $(84)/(100) = (x)/(300)$ . I like to use the cross-multiply method, which just means you multiply by a diagonal and then divide by what's left. This would give us 300 x 84 = 25,200/100 = 252. Hope this helps!

GEOMETRY. PLEASE CHECK MY ANSWER! THANKS.Mario’s company makes unusually shaped imitation gemstones. One gemstone had 12 faces and 10 vertices. How many edges did the gemstone have?

A. 23 edges
B. 22 edges
C. 25 edges
D. 20 edges****

Answers

I'd solved it in the pic, and the answer is D. 20

This is simple.
we should have a knowledge of the Euler's Theorem/Euler's Formula
F+V=E+2
Basically states that:
# of Faces+ # of Vertices= # of Edges+2
12 + 10 = E + 2
(-2) + 22 = E + 2 (-2)
20 = E

Yep, The answer is D. 20 edges
