To answer this question, we need to understand the ratio of the question, which in this case is 3:4. If this ratio remains constant, then a simple way to solve this would be to multiply the 4 (in this case) so that it becomes 24 (because we know that these parts of the ratio correspond to each other). Since we know that 4*6=24, we can multiply both numbers included in the ratio by 6 to find our answer. After doing this, we find the ratio to be 18/24, which means that for every 24 buckets of gravel used, 18 buckets of sand are used.

So, the answer to this question is A. 18 buckets.

I know they study the Torah and Hebrew is their ancient language. They believe in one god and practice their religion in a temple. Judaism is very interesting because other religious like Christianity branch of of it. It is like a ancestor to other religions.

Is this wrong?

sammy [17]

Step-by-step explanation:

The last step is a little wrong. Lemme show you:

x(x + 2) + (x + 2)

Imagine there is an invisible '1' infront of (x + 2) like this:

= x(x + 2) + 1(x + 2)

Now we can combine the like terms together:

= (x + 1)(x + 2)

This is the correct factorization.

C and D are mutually exclusive events. Find P(C or D).<br> P(C)= 3/7= P(D)= 4/7<br> P(C or D)

IgorLugansk [536]

Answer:

$P(C\ or\ D) = 1$

Step-by-step explanation:

Given

$P(C) = \frac{3}{7}$

$P(D) = \frac{4}{7}$

Required

$P(C\ or\ D)$

Since the events are mutually exclusive, then:

$P(C\ or\ D) = P(C) + P(D)$

So, we have:

$P(C\ or\ D) = \frac{3}{7} + \frac{4}{7}$

Take LCM

$P(C\ or\ D) = \frac{3+4}{7}$

$P(C\ or\ D) = \frac{7}{7}$

$P(C\ or\ D) = 1$

Pls pls pls pls help

artcher [175]

Answer:

see below

Step-by-step explanation:

A. Reflection across the y-axis replaces each x coordinate with its opposite.

B. Rotation 90° CW does the transformation (x, y) ⇒ (y, -x)

C. This is a translation left 2 units.

D. Rotation 90° CCW does the transformation (x, y) ⇒ (-y, x)

E. This is a translation left 7 and down 2.

In the attached graphs, we have identified a point that is a corresponding point on each figure. This is so you can see how the various transformations move it and the rest of the figure in relation to it. 90° arcs are shown so you can see the rotations more easily.

The figures are labeled and color coded in accordance with the problem statement.
