Answer:
10z+34
Step-by-step explanation:
I am going to assume ‘centimetre’ was a typo.
A^2 + B^2 = C^2
C^2 - A^2 = B^2
32 = B^2
Square root both sides
B = 5.7m high
The ladder will reach 5.7 meters high
Answer:
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- The sum of two numbers is 52.
- The product of the numbers is 4 .
And we need to find the sum of reciprocals of the numbers. For that let us assume that the numbers are .
<u>According</u><u> to</u><u> </u><u>1</u><u>s</u><u>t</u><u> </u><u>condition</u><u> </u><u>:</u><u>-</u><u> </u>
Now expressing this equation by keeping only one variable on one side as ,
<u>According</u><u> to</u><u> </u><u>2</u><u>n</u><u>d</u><u> </u><u>condition</u><u> </u><u>:</u><u>-</u>
- Now solve this quadratic equation.
On solving the equation using quadratic Formula we will get the value of y as ,
- Note that the sum of x and y is 52 .So in order to find the value of x we will subtract 26±4√42 from 52 and we will get the value of x same as y .
Now we need to find out the sum of reciprocal of the two numbers . That will be ,
<u>Hence</u><u> the</u><u> </u><u>sum </u><u>of</u><u> </u><u>their </u><u>reciprocals </u><u>is </u><u>1</u><u>3</u><u> </u><u>.</u>
Answer:
see below
Step-by-step explanation:
The costs are
2230.80 + .03 b where b is the board foot
the income was 1.13b
Profit is income - costs
Profit = 1.13b - (2230.80 + .03 b)
Distribute
= 1.13b - .03b - 2230.08
= 1.10b - 2230.08
Profit is when the money is greater than 0
(breaking even is 0)
0 <1.10b - 2230.08
Add 2230.08 to each side
2230.08 < 1.10b - 2230.08 + 2230.08
2230.08 < 1.10b
Divide by 1.10
2230.08/1.10 < 1.10b/1.10
2027.345455 <b
They must sell at least 2027.345 board feet of lumber per day to make a profit
Answer:
8 times
Step-by-step explanation:
3/4 n = 6
Multiply each side by 4/3 to isolate n
4/3 * 3/4 n = 6*4/3
n = 8
