Answer:
The first answer is 0.85090352453
The second answer is 0.0883686861
Step-by-step explanation:sin 45 is 0.85090352453 and sin 135 is 0.0883686861
We have to determine a ratio that is equivalent to 7:4. We already know that 60 students didn’t bring a water bottle. So in order to determine the conversion, we divide 60 by 4 to get 15. Now that we know how to produce the ratio we must determine, we can multiply 15 by 7 as well (number of students who brought a water bottle) and get 105. Now all we have to do is add these up 105+60 is 165 total students:)
Answer:
Step-by-step explanation:
It would be a Right scalene triangle
Volume of the cube = a³ = (14cm)³= 2744 cm³
To find surface are, we need to find at first area of the face
A(face)=14² cm².
Cube has 6 congruent squares, so
Surface area of the cube = 6*14² cm²= 1176 cm²
