Find the length of the base of a square pyramid if the volume is 128 cubic inches and has a height of 6 inches

Mathematics

Answer: a = 8

Step-by-step explanation:

Volume of a square based pyramid is given as

\frac{a^{2}h }{3} .

where a is the length of the side and h is the height.

Substituting into the formula , we have

V = \frac{a^{2}h }{3}

128 = a^{2}h /3

384= a^{2} X 6

Divide through by 6

384/6 = a^{2}

64 = a^{2}

Therefore :

a = \sqrt{\frac{64}{1} }

a = 8

If a sponsored link was delivered 100 times and 10 people clicked on it, then the number of impressions is 100, the number of cl
Rudik [331]

Answer:

Option A.

Step-by-step explanation:

It is given that a sponsored link was delivered 100 times and 10 people clicked on it.

Number of impressions = 100

Number of clicks = 10

The formula for click-through-rate (CTR) is

CTC=\dfrac{\text{Total measured clicks}}{\text{Total measured impression}}\times 100

CTC=\dfrac{10}{100}\times 100

CTC=10

The click-through-rate (CTR) would be 10%. Therefore, the correct option is A.

Point B is the center of a circle, and AC is a diameter of the circle. Point D is a point on the circle different from A and C.
seropon [69]

BA and BD are radii of the circle, so triangle ABD is isosceles. Then angles BDA and BAD are congruent, and the remaining (central) angle ABD has measure

m\angle ABD=(180-2\cdot20)^\circ=140^\circ

Angles ABD and CBD are supplementary, so

m\angle CBD=(180-140)^\circ=40^\circ

and the answer is E.

What do I do on this?
stiks02 [169]
All you do is measure it with a ruler and for every 1 cm you get multiply it by 8.5ft. 
so for example if you got 6cm then you would multiply it by 8.5ft and your answer would be 51ft.

Answer:

A) slope = 20.

B)  The slope of 20 dollars per hour means that for every hour, the price of the service call increases by 20 dollars (or you could say the price of the service call is 20 dollars every hour, both work.)

Step-by-step explanation:

Recall that slope is y2 - y1 / x2 - x1.

Excellent. We are provided with two points: (1, 60) and (3, 100). Let’s enter this into our formula.

Slope = (100 - 60) / (3 - 1) = 40 / 2 = 20.

Now, to determine what the slope means, we can look at the axis titles on the graph. The x axis title is hours, or time in hours. The y axis title is price of the service call in dollars. Therefore, the slope is price (in dollars) per time (in hours).

This can be restated as: The slope of 20 dollars per hour means that for every hour, the price of the service call increases by 20 dollars (or you could say the price of the service call is 20 dollars every hour, both work.)

Hope this helps!
