A cone has a radius of 5 inches and a height of 18 inches.

1 answer:

5 0

It would be C., because to find the volume, you would have to multiply the radius by itself, to get the diameter. Then, the answer you get will have to be multiplied by the height.: 5 times 5 equals 25, and then 25 times 18 equals 450.

parker correctly answered 70% of the questions on his math test. If he answered 35 questions correctly, how many questions were

Alexandra [31]

Let the total number of questions in the math test be defined by the variable x.

Now, we know that Parker correctly answered 35 questions. These 35 questions make 70% of the total number of questions on his math test.

The information we have above can be expressed as an equation given below:

70% of x=35

This can be rewritten as:

$\frac{70}{100}x=35$

Thus, to find the total number of questions we will have to isolate x.

$\therefore x=\frac{35\times 100}{70}=50$

Therefore, there were a total of 50 questions in the math test.

The tangent meets the radius at a right angle.

We use (the converse of) the Pythagorean Theorem to check:

$26^2 + 17^2 = 965 \ne 30^2$

Not a right triangle

in a certain store, the regular price of a refrigerator is $600. how much money is saved by buying the refrigerator at 20% off t

Advocard [28]

60$. These are my equations :
600 * 0.2 = 120 ; 600 - 120 = 480
Then...
600 * 0.1 = 60 ; 600 - 60 = 540
Which then became....
540 - 480 = 60

Please I need step by step solution.

4vir4ik [10]

Answer:

A) 2C

Step-by-step explanation:

The relevant rule of logarithms is ...

log(x²) = 2·log(x)

We know that 64 = 8². So, ...

log(64) = log(8²) = 2·log(8)

We are given that log(8) = C, so 2·log(8) = 2C

Here, all logarithms are to the base 9. That does not change the relations shown.
