A.43 72-12=60+3=63-20=43

20 came from temperature dropping 2 degrees every 30 minutes for 5 hours means that it dropped a total of 10 times, and 10x2=20 so the answer is 43

About 9/10 Of the avocados grown in the United States are in California about what percent of our car is going in the United Sta
artcher [175]

Answer:

9/10 x 100% = 90%

Step-by-step explanation:

The question is asking us to convert the given fraction, 9/10, to percentage. As we know, to convert any number to percentage, we simply multiple by 100%. We are not changing the value because 100% means 100/100 = 1. So, we are basically multiplying by 1.

Since we are told that 9/10 avocados grown in the US are grown in California, then the percentage would be:

9/10 x 100% = 90%

Help ASAP Please!!!!
g100num [7]

Answer: 18

Step-by-step explanation: The equation of a square pyramid is V=1/3BH

where V=Volume, B=Base, and H=Height if you set it equal to B then plug in all the numbers you'll get 18 meters squared.

B= 3(V/H)

B= 3(72/12)

B= 3(6)

B= 18

Your welcome

4. A horizontal ellipse, centered at the origin has a major axis of 10 units and minor axis of 8 units. Write the
s2008m [1.1K]

Answer:

\frac{x^2}{25} +\frac{y^2}{16} =1

Step-by-step explanation:

For ellipses, the length of the major axis is represents as:

Major axis = 2a

where a is called the semi-major axis.

In this case since the major axis is equal to 10 units:

10=2a

solving for the semi-major axis a :

a=10/2\\a=5

and also the minor axis of an ellipse is represented as:

Minor axis = 2b

where b  is called the semi-minor axis.

Since the minor axis has a length of 8 units:

8=2b

solving for b:

b=8/2\\b=4

Now we can use the equation for an ellipse centered at the origin (0,0):

\frac{x^2}{a^2} +\frac{y^2}{b^2} =1

and substituting the values for a and b:

\frac{x^2}{5^2} +\frac{y^2}{4^2} =1

and finall we simplify the expression to get the equation of the ellipse:

\frac{x^2}{25} +\frac{y^2}{16} =1
