No because the difference between 1.3 and 1.4 is .1
Answer:
the weight of 24 bricks is :
![124\frac{4}{5}](https://tex.z-dn.net/?f=124%5Cfrac%7B4%7D%7B5%7D)
Step-by-step explanation:
![26\frac{1}{4} =26+\frac{1}{4} =\frac{26\times 4}{4} +\frac{1}{4} =\frac{105}{4}](https://tex.z-dn.net/?f=26%5Cfrac%7B1%7D%7B4%7D%20%3D26%2B%5Cfrac%7B1%7D%7B4%7D%20%3D%5Cfrac%7B26%5Ctimes%204%7D%7B4%7D%20%2B%5Cfrac%7B1%7D%7B4%7D%20%3D%5Cfrac%7B105%7D%7B4%7D)
It is clear that there is a proportional relationship between the number of bricks and their weights then :
![\frac{26\frac{1}{4} }{5} =\frac{x}{24} \Longrightarrow \frac{\left( \frac{105}{4} \right) }{5} =\frac{x}{24} \Longrightarrow \frac{26}{5} =\frac{x}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B26%5Cfrac%7B1%7D%7B4%7D%20%7D%7B5%7D%20%3D%5Cfrac%7Bx%7D%7B24%7D%20%5CLongrightarrow%20%5Cfrac%7B%5Cleft%28%20%5Cfrac%7B105%7D%7B4%7D%20%5Cright%29%20%20%7D%7B5%7D%20%3D%5Cfrac%7Bx%7D%7B24%7D%20%5CLongrightarrow%20%5Cfrac%7B26%7D%7B5%7D%20%3D%5Cfrac%7Bx%7D%7B24%7D)
![\Longrightarrow x=\frac{26\times 24}{5} =\frac{624}{5} =124\frac{4}{5}](https://tex.z-dn.net/?f=%5CLongrightarrow%20x%3D%5Cfrac%7B26%5Ctimes%2024%7D%7B5%7D%20%3D%5Cfrac%7B624%7D%7B5%7D%20%3D124%5Cfrac%7B4%7D%7B5%7D)
Answer:
when the negative is outside of the parenthesis like in
-(-(2)) you need to distribute the negative to all the numbers within the parenthesis.
so in the case of -(-(2)) the first negative would distribute inside the parenthesis making the answer positive 2
you can also just enter it in your calculator
The answer is A. All i did was i added all the numbers and i got 367. After that i divided 367 by 23 and got 0.06.
Answer:
cosA = ![\frac{5}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B13%7D)
