Answer:

the smallest part is 2

Step-by-step explanation:

lets take x as the smallest part

then the largest part=3x

the middle sized part=2x

x+2x+3x=12

6x=12

x=12/6

x=2

therefore the smallest part is equal to 2

Andre says that 5 3/4 + 2 1/4 = 7 1/2 because 7 4/8 = 7 1/2. Identify his mistake. Draw a picture to prove that he is wrong.
MA_775_DIABLO [31]

Answer:

Step-by-step explanation:

The given expression is

5\frac{3}{4}+2\frac{1}{4} =7\frac{4}{8}=7\frac{1}{2}

We will rewrite the expression

\frac{23}{4}+\frac{9}{4} =\frac{60}{8}=7\frac{1}{2}

When we add the fraction

\frac{23+9}{4} = \frac{32}{4} = 8

While Andre says the answer is 7\frac{1}{2}

because Andre added the denominator where he has to make a common denominator that should be 4 instead of 8.

Andre made mistake in this step

Picture is given below :

Based on experimental data, the function T(x) = -3(x − 4)^3 + 10 models the temperature of a special substance after being place
Ainat [17]

I can't say for sure this answer is 100% correct because I think more info is needed.

If your teacher is looking for the turning point, then that would be (4,10)

The equation y = a(x-h)^3 + k has a turning point at (h,k). The parent function y = x^3 gets shifted h units to the right (assuming h is positive) and k units up (if k is positive). In this case, (h,k) = (4,10) so we have y = a(x-4)^3 + 10. The original turning point (0,0) has been shifted to the new turning point (4,10) which is 4 units to the right and 10 units up. The value of 'a' does not effect the turning point.

If x was say the time in minutes and y was the temperature, then the turning point of y = -3(x-4)^3 + 10 could mean that at time 4 minutes (x = 4) the substance turns from liquid to solid (y = 10 degrees).

Note: more information is needed about this function be 100% certain about the claim made.
