I'm confused... you can't have 2 decimals in a number.... anyway I'm going to help solve it as if the number was 10.5105
The formula for the area of a triangle is A = 1/2bh. So, if you were given the base and height and asked to find the area, you would multiply the base and height then divide by 2 (or multiply by 1/2, same thing). Here you have to do the opposite. Take the area, multiply it by 2, then divide it by the base.
10.5105(2) = 21.021
21.021/66 = 0.3185
h = 0.3185 ft
Hope this helped even if 0.3185 isn't the correct answer <span>because <span>10.510.5 doesn't make sense lol</span>.</span>
Make y the subject:
2x+y=-5
2x+5=-y
y=-2x-5
y=-2x+2 is the answer as the slope does not change but the y intercept does
The answer is A, good luck!
Answer: (I'm sorry if this is not the right answer)
The width = 8 meters
Step-by-step explanation:
The length: a (m)
The width: b (m)
We cannot have a negative length and a negative width: a>b>0
Eq. I: a=2b-4
Eq. II: ab=96
Substitute the value of a from Eq. I into Eq. II: (2b-4).b=96
Solve for b:
(2b-4).b=96
2-4b-96=0
-2b-48=0
+6b-8b-48=0
b.(b+6)-8.(b+6)=0
(b+6).(b-8)=0
b=8; b=-6
As mentioned above, b>0. Therefore, b=8
Conclusion: if the area of the rectangle is 96 square meters then its width is 8 meters.
Answer:
60 boys are in the grade.
Step-by-step explanation: Since there are 150 students, we can divide that number by the combined ratio, which in this case is 5. Dividing 150 by 5 would yield 30 students. We can use this information to multiply the given number of boys in the ratio by 30, which would produce 60.
