Answer:
12. C. 40 more students chose baseball than basketball
20. 500 total flowers
Step-by-step explanation:
12. To find the number of students that chose baseball, we multiply 25% by 800 students surveyed. First we have to convert 25% to a decimal = 0.25
800 x 0.25 = 200 students chose baseball.
Then, for basketball, 20% of students chose that, so 20% = 0.20
800 x 0.2 = 160 students chose basketball
200-160 = 40 more students chose baseball than basketball
----------------------------
20. I don't know what your "magic sentence" looks like. You can set this up as a ratio, where x is the total number of flowers, and the 56% is a fraction of 56/100
280/x = 56/100
then cross multiply
28,000 = 56x
divide by 56
x = 500
Check the math: 500 x 0.56 = 280
If you want to tell me what your teacher's "magic sentence" looks like in the comments, I can try to fill it in with/for you.
I found this!!!!
The scientist can use these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.
- The scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=
hypotenuse
adjacent
and solve for the distance between the Sun and the shooting star (which would be the hypotenuse of the righ triangle).
Step-by-step explanation:
You can observe in the figure attached that "AC" is the distance between the Sun and the shooting star.
Knowing the distance between the Earth and the Sun "y" and the angle x°, the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.
This is:
cos\alpha=\frac{adjacent}{hypotenuse}cosα=
hypotenuse
adjacent
In this case:
\begin{gathered}\alpha=x\°\\\\adjacent=BC=y\\\\hypotenuse=AC\end{gathered}
α=x\°
adjacent=BC=y
hypotenuse=AC
Therefore, the scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=
hypotenuse
adjacent
, and solve for the distance between the Sun and the shooting star "AC":
cos(x\°)=\frac{y}{AC}cos(x\°)=
AC
y
AC=\frac{y}{cos(x\°)}AC=
cos(x\°)
y
Answer:
To make 6 cups, you will need 2 cups of lemon and 4 cups of water....6 total
TWO of the six are lemon 2/6 x 100 = 33.33% Lemon the rest is water 100-33.33= 66.67% water
OR
FOUR out of the SIX are water 4/6 x 100 = 66.67% Water
