Answer:
190.28in
Step-by-step explanation:
Sides= 31.2
Front and back= 58.2
Top and bottom= 100.88
Add them together= 100.88+58.2+31.2
13 1/3 bags.
We start off with:
8 x 1 2/3
Convert the mixed number into an improper fraction:
8 x 5/3
Multiply:
40/3
Simplify:
13.333...
Convert decimal to fraction:
13 1/3
3x + 4y = 16 Subtract 4y from both sides. Put brackets around the 2 terms on the right.
3x + 4y - 4y = (16 - 4y)
3x = (16 - 4y) Divide by 3
Answer That's B.
Answer:
X=24, Y=7
Step-by-step explanation:
We use the concept of similarity.
By observing the figure, we notice that the hypotenuse is 50, and the hypotenuse of the smaller triangle is 25.
That means the hypotenuse of the larger triangle is double the hypotenuse of the smaller triangle. Meaning, the other sides of the larger triangle would be double the smaller sides of the smaller triangle.
We already have the sides of the larger triangle, divide them by two to get x and y.
X = 48/2 = 24
Y = 14/2 = 7
This question would actually go under physics
Assuming that the model rocket goes straight up into the air and not at an angle, you can calculate for the maximum height by finding how long it takes for the velocity of the rocket to reach 0.
This can be calculated using the equation
t = (v sinx) /g
where t=time, v=velocity at zero seconds, x=angle of launch, g=gravity
Since we are assuming that the rocket flies straight up, the angle would be 90º, so sinx would be equal to 1.
That reduces are equation to
t = v / g
g=9.81 m/s^-2
So we need to convert gravity to feet/second^-2 and divide 160 by g, 160 being the initial velocity.
g=9.81 m/s^-2 = <span>32.2 ft/s^-2
160/32.2 ≈ 4.97 seconds
