Answer:

<h2>The Slant height of the pyramid is 7 yards.</h2>

Step-by-step explanation:

The total surface area is 125 square yards.

The base area is 37.5 square yards.

Hence, the area of the curved surface is 125 - 37.5 = 87.5 square yards.

According, to the formula, the area of the curved surface is \frac{5}{2} \times bs, where b is the base length and s = slant height.

Here, it is given that b = 5 yards.

Thus, \frac{5\times5\times s}{2} = 87.5\\s = 7.

What is 19 - 6x = 29
notka56 [123]

Answer:

x = (-5)/3

Step-by-step explanation:

Solve for x:

19 - 6 x = 29

Hint: | Isolate terms with x to the left hand side.

Subtract 19 from both sides:

(19 - 19) - 6 x = 29 - 19

Hint: | Look for the difference of two identical terms.

19 - 19 = 0:

-6 x = 29 - 19

Hint: | Evaluate 29 - 19.

29 - 19 = 10:

-6 x = 10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -6 x = 10 by -6:

(-6 x)/(-6) = 10/(-6)

Hint: | Any nonzero number divided by itself is one.

(-6)/(-6) = 1:

x = 10/(-6)

Hint: | Reduce 10/(-6) to lowest terms. Start by finding the GCD of 10 and -6.

The gcd of 10 and -6 is 2, so 10/(-6) = (2×5)/(2 (-3)) = 2/2×5/(-3) = 5/(-3):

x = 5/(-3)

Hint: | Simplify the sign of 5/(-3).

Multiply numerator and denominator of 5/(-3) by -1:

Answer: x = (-5)/3

Tourists from a tour bus were asked about places they visited during their stay in a city. The results are shown in the table.
denis23 [38]
So I added all of the numbers of tourists together, I got 30 tourists. Then I saw that the number of tourists that visisted the museum but not the zoo was 5. I divided 5 by 30 and got that there was a 16% chance that a randomly selected tourist would of visited the museum but NOT the zoo. 
Hope this helps!
