I'll be using these log rules

which I'll refer to as "rule 1" and "rule 2" respectively. There are other log rules, but we only need to use these two for this particular question.

Here's how the steps could be laid out:

Answer:

2nd option

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h is its height )

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

here b = 30, h = 8 , then

A = [tex]\frac{1}{2}[/tex] × 30 × 8 = 15 × 8 = 120 in²

with h = 15 , then

V = 120 × 15 = 1800 in³

Pattern: subtract 2 from the input to get the output

When the input is 9, the output is 7

When the input is 13, the output is 11

Step-by-step explanation:

Step-by-step explanation:

The truck does 3 sides of the square     3 x 24 = 72

   and the truck does one entire diagonal of the square

          with side lengths 24

       diagonal = sqrt (24^2 + 24^2 ) = 33.94 miles

total miles 33.94 + 72 = 105.94 miles in 4.5 hours

    105.94 / 4.5 = 23.54 m/hr for the entire trip

The mph for the actual driving time (2.5 hours )

   105.94 / 2.5 = 42. 38 m/hr    for driving time only

Answer: 1pi or 3.14

Step-by-step explanation:

Step-by-step explanation:

Im pretty good with space so your answer would be C

The correct statement regarding the measurements of the parallelogram is that the base is 9 and the height is 7, so the area is 9 (7) = 63 square units.

This is defined as a quadrilateral which has two pairs of parallel sides present and the area is base × height.

The base is 9 and the height is 7, when the points are plotted which results in the area being 63 square units hence option D was chosen.

Answer:

- 30 + 5v

Step-by-step explanation:

- 3(10 - 5v) - 10v ( multiply each term in the parenthesis by - 3 )

= - 30 + 15v - 10v ← collect like terms

= - 30 + 5v

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

Let's solve ~

[tex]\qquad \sf  \dashrightarrow \: - 3(10 - 5v) - 10v[/tex]

[tex]\qquad \sf  \dashrightarrow \: - 30 + 15v - 10v[/tex]

[tex]\qquad \sf  \dashrightarrow \:5v - 30[/tex]

so, the equivalent expression is 5v - 30

Answer:

I believe it would be 30%

Step-by-step explanation:

If we look through the list of coin flips for each time there is a group (of 3) that has 2 tails and 1 heads, we would find that there are 10 groups.

So to solve this we can simply divide 10 (the amount of groups with 2 tails) by 30 (the total amount of groups) which gives us 33.333%. Now this isn't really an exact answer, but it is closer to 30% than it is to 35% so it would probably be safe to say that we could round down.

A fraction, like 2/9, has a numerator and a denominator separated by a dividing line.

2 is the numerator, because it is the number above the dividing line.

9 is the denominator because it is the bottom number of the dividing line.

To convert 2/9 to a decimal, divide the numerator by the denominator.

Answer:

A.  The probability of event B​ occurring, given that event A has occurred

Step-by-step explanation:

Conditional probability

A probability is conditional if is depends on what has already happened.

The probability that event B happens, given that event A has already happened is "B given A" or P(B | A)

Therefore, P(B | A) means "The probability of event B​ occurring, given that event A has occurred"

Additional information:

P(A | B) means "A given B", i.e. the probability of event A​ occurring, given that event B has occurred

P(A ∩ B) means the probability of event A and event B both happening.

Answer:

A. True

Step-by-step explanation:

Given:

O is the center of the Circle

Chord BC is the line segment passing from the center of circle

Chord: It is a line segment whose end points lies on the circle.

Diameter: It is defined as a line segment passing from the center of the circle whose end point lies on the circle.

Hence chord BC is a diameter of the circle as passes from the center O of the circle and its end points B,C lies on the circle.

Hence the statement is TRUE

Yes, The chord BC is a diameter of circle C.

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

We have to given that;

To check The chord BC is a diameter of circle C.

Now, WE know that;

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Here, The line segment BC is passing through the center O.

Hence, The chord BC is a diameter of circle C.
