The correct answer would be 6×7×2.
Answer:
- 340 dimes and 232 quarters
Step-by-step explanation:
Let the number of dimes be x and quarters be y.
- Dime = 10 cents, quarter = 25 cents, total amount is $92 = 9200 cents
<u>We have equations:</u>
- x + y = 572
- 10x + 25y = 9200
<u>Multiply the first equation by 10 and subtract from the second one:</u>
- 10x + 25y - 10x - 10y = 9200 - 5720
- 15y = 3480
- y = 3480/15
- y = 232
<u>Find the value of x:</u>
- x + 232 = 572
- x = 572 - 232
- x = 340
Y=-3x+-1. you subtract (-4)-(-1) =3 and 1-0 and you get 1 . so the slope is 3 over 1 . and the y intercept is -1
This is a simple problem with some quick addition and subtraction, and a bit of multiplication.
First we figure out how much money you're spending in total, which is $300 each year, for 20 years, so 300 x 20 = 6,000. Now, since the problem is asking for a maximum amount for percentage rate, this means we find the 9% for all 20 years combined and not individually. 9% of 6,000 is of course 540, so if we subtract 540 from 6,000, we get 5,460.
This means your answer is $5,460
Answer:
Firstly, from the diagram we are given that the length of XB is congruent to BZ, and YC is congruent to CZ. Based on this information, we know that B is the midpoint of XZ, and C is the midpoint of YZ. This means that BC connects the midpoints of segments XZ and YZ. Now that we know this, we can use the Triangle Midsegment Theorem to calculate the length of BC. This theorem states that if a segment connects the midpoints of two sides of a triangle, then the segment is equal to one-half the length of the third side. In this scenario, the third side would be XY, which has a length of 12 units. Therefore, the length of BC = 1/2(XY), and we can substitute the value of XY and solve this equation:
BC = 1/2(XY)
BC = 1/2(12)
BC = 6
