Answer:
For longest x = 6.4
For shortest x = 3
Step-by-step explanation:
Given a right angle triangle with lengths 4 units and 5 units and x units .
x can be gotten using Pythagoras theorem .
If x Is the longest side , then
x^2 = 5^2 + 4^2
= 5x5 + 4x4
= 25 + 16
x^2 = 41
x = squared root of 41
x = 6.4
If x is the shortest side ,
x^2 = 5^2 - 4^2
= 5x5 - 4x4
= 25 - 16
x^2 = 9
x = squared root of 9
x = 3
Where is x and y ? i don’t see it in the equation
First, let’s find the area of the larger square. We know that the smaller square extend out 2ft and is2ft up. Well take these measures, and subtract the 2ft from the 12 ft at the top, and get 10ft, then add the 2ft to the left side, and find that it’s 6ft. We have these measures: 6ft 6ft 10ft 10ft for the larger rectangle. Let’s find the area. The are formula for a rectangle is Base(10ft) times height(6ft) . Thus 60ftsqrd. Next, let’s do the smaller rectangle. We do the same formula, 4 times 2, and get 8ftsqrd, add them together: 60ft + 8ft = 68ft!
Use the velocity formula and solve for time.v=d/t
t=d/v
Substitute your variables and solve.
65 mi/hr = 65 / 3600 mi/second
25 mi / ( 65/3600) = 1384.6 seconds
The number of pennies in bank is 42
<em><u>Solution:</u></em>
Given that ratio of pennies to quarters in a piggy bank is 14 : 3
Let 14x be the number of pennies in piggy bank
Let 3x be the number of quarters in piggy bank
<em><u>To find: number of pennies</u></em>
Given that there are 51 quarters
number of pennies in piggy bank + number of quarters in piggy bank = 51
14x + 3x = 51
17x = 51
x = 3
number of pennies = 14x = 14(3) = 42
Thus the number of pennies in bank is 42
