I need help on finding the height of a triangular pyramidif there’s no work, I don’t get credit

I will give Brainliest

Answers

Answer:

20 in

Step-by-step explanation:

The formula for the volume of a triangular pyramid is V=1/3 x B x H, in which B is the area of the base and H is the height. You're given the volume and area of the base so you can just plug that into the formula. You will get 120 = 1/3 x 18 x H. You can multiply the 1/3 and 18 so you will get 120 = 6H. In this case, you are solving for H so you need to isolate the variable. You can do this by dividing both sides by 6. You will end up eith 20 = H.

A line passes through the point (2, 7) and has a slope of 4. What is the equation of the line?

Answers

Answer:

y=4x-1

Step-by-step explanation:

Remember the point slope form equation y-y1=m(x-x1) where m is the slope and the given point is (x1,y1)

y-7=4(x-2) . Plug in the numbers for the equation

y-7=4x-8   distributive property

y = 4x-1

y=4x-1 is the equation that passes through (2,7)

Log8 (t) - log8 (5) = 1

Answers

Answer:

t = 40

Step-by-step explanation:

Given the logarithmic expression: log_8 (t) - log_8 5= 1

Use the Logarithmic Property (Quotient Rule):

log_b a - log_b c = log_b ((a)/(c))

log_8 (t) - log_8 5 = log_8 ((t)/(5)) = 1

Next, using the Logarithmic Property:  log_b b= 1

We must determine the possible value oft that can be divided by 5 to produce a quotient of 8 that will make the logarithmic property, log_b b= 1, true.  In that case, t = 40 divided by 5 results in a quotient of 8.

log_8 (t) - log_8 5 = log_8 ((t)/(5)) = log_8 ((40)/(5)) = log_8 8 = 1

Therefore, the value oft = 40.
