The correct answer will be:
![-\dfrac{62}{23}](https://tex.z-dn.net/?f=-%5Cdfrac%7B62%7D%7B23%7D)
Step-by-step explanation:
It is given that :
Initial temperature, ![T_1 = 0^\circ F](https://tex.z-dn.net/?f=T_1%20%3D%200%5E%5Ccirc%20F)
Final temperature,
![T_2 = -15\dfrac{1}{2}^\circ F\\\Rightarrow T_2 = -\dfrac{15\times 2+1}{2} ^\circ F\\\Rightarrow T_2 = -\dfrac{31}{2} ^\circ F](https://tex.z-dn.net/?f=T_2%20%3D%20-15%5Cdfrac%7B1%7D%7B2%7D%5E%5Ccirc%20F%5C%5C%5CRightarrow%20T_2%20%3D%20-%5Cdfrac%7B15%5Ctimes%202%2B1%7D%7B2%7D%20%5E%5Ccirc%20F%5C%5C%5CRightarrow%20T_2%20%3D%20-%5Cdfrac%7B31%7D%7B2%7D%20%5E%5Ccirc%20F)
Time taken :
![5\dfrac{3}{4}\ hrs = \dfrac{5 \times 4+3}{4}\ hrs = \dfrac{23}{4}\ hrs](https://tex.z-dn.net/?f=5%5Cdfrac%7B3%7D%7B4%7D%5C%20hrs%20%3D%20%5Cdfrac%7B5%20%5Ctimes%204%2B3%7D%7B4%7D%5C%20hrs%20%3D%20%5Cdfrac%7B23%7D%7B4%7D%5C%20hrs)
Change in temperature per hour:
![\dfrac{\text{Difference of temperature}}{\text{Total Time Taken}}\\\Rightarrow \dfrac{T_2-T_1}{\text{Total Time Taken}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BDifference%20of%20temperature%7D%7D%7B%5Ctext%7BTotal%20Time%20Taken%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7BT_2-T_1%7D%7B%5Ctext%7BTotal%20Time%20Taken%7D%7D)
Putting the values of temperatures and time:
![\dfrac{\dfrac{-31}{2}-0}{\dfrac{23}{4}}\\\Rightarrow \dfrac{\dfrac{-31}{2}}{\dfrac{23}{4}}\\\Rightarrow \dfrac{-31 \times 4}{2 \times 23}} \text{---- Error done by Wen at this step}\\\Rightarrow \dfrac{-31 \times 2}{23}}\\\Rightarrow \dfrac{-62}{23}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B-31%7D%7B2%7D-0%7D%7B%5Cdfrac%7B23%7D%7B4%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B%5Cdfrac%7B-31%7D%7B2%7D%7D%7B%5Cdfrac%7B23%7D%7B4%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B-31%20%5Ctimes%204%7D%7B2%20%5Ctimes%2023%7D%7D%20%5Ctext%7B----%20Error%20done%20by%20Wen%20at%20this%20step%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B-31%20%5Ctimes%202%7D%7B23%7D%7D%5C%5C%5CRightarrow%20%5Cdfrac%7B-62%7D%7B23%7D%7D)
The error done by Wen was during calculating the values of fraction.
So, the correct answer is :

Answer:
We can see that both the triangles are congruent to each other.
So, PQ = TU (CPCT), Thus TU = <u>6</u><u>0</u><u>.</u>
Answer:
height=100feet
Step-by-step explanation:
perimeter of a rectangle=p=500 feet
p=2a+2b equation 1
a=height
b=base
we have: b/a=3/2
so a=(2*b)/3
in equation 1 we have:
500=2*((2*b)/3)+2*b
so we have
500=(4*b)/3 + 2*b
500=(4b+6b)/3
500=(10b)/3
500*3=10b
b=(500*3)/10
b=150 feet =base
so
a=(2*150)/3=100 feet = height
Answer:
2.32 x 10 put the minus sign at the top with a 11.
Step-by-step explanation:the answer is: move the decimal so there is one non-zero digit to the left of the decimal point. the number of decimal places you move will be the exponent on the 10. the sign of the exponent will depend on the direction you are moving the decimal. hope this helps! ;)
