Answer:
The mass of Jupiter is about 27,000 times the mass of Earth's moon
Step-by-step explanation:
Let
x -----> the mass of Earth's moon
y ----> the mass of Jupiter
we have
we know that
To know how many times the mass of Jupiter is approximately the mass of the earth's moon, divide the the mass of Jupiter by the mass of the earth's moon
so
therefore
The mass of Jupiter is about 27,000 times the mass of Earth's moon
Answer:
The depth of the reflector is 700 feet.
Step-by-step explanation:
The cross section of a parabolic reflector is just a parabola (see the figure below). Because it has a vertical axis of symmetry and its vertex is at (0,0) the equation of the parabola is:
With p the distance to the focus (p=6ft), the equation for our particular case is:
Note that because the reflector extends 5.5 feet to either side of the vertex, the extreme sides of the parabola are on the curve so they satisfy our parabola equation (3). Let’s concentrate on the right extreme of our parabola with x-position 5.5 ft using this number on (3) equation we can find the respective y-position
and that correspond to the depth of the parabolic reflector.
Answer:
y=2
Step-by-step explanation:
8y-5y-13=-7
3y-13=7
3y=-7+13
3y=6 /3
y=2
Answer:
242
First is 9 times 10 which is 90, then 4 times 8 is 32 divided by 2 which is 16 times 2 since there are two, 32 again. 8 times 10 is 80. 4 times 10 is 40.
90 + 32 + 80 + 40 = 242
Step-by-step explanation:
Let's divide and see how much the popcorn cost per ounce, then we can see which is the better priced brand.
first brand: 16 ounces + 9 ounces = 25 ounces
$2.00/25ounces = $0.08
second brand: 16 ounces + 14 ounces = 30 ounces
$2.10/30ounces = $0.07
So, since $0.08 is less than $0.07, the second brand is the better buy.
