Find the surface area of a square pyramid with side length 3 cm and slant height 3 cm

Answers

Answer 1

Answer:

Step-by-step explanation:

base length b = 3 in

slant height L = 3 in

base area = b² = 3² = 9 in²

lateral area = 4·½bL = 4·½·3·3 = 18 in²

surface area = base area + lateral area = 27 in²

Okay so you would use the formula to find all sides which is: a2+b2=c2(pretend it’s squared, my keyboard isn’t fancy) then you would plug in the sides into the formulado it would be
5.5+x=12(everything is still squared)
After simplifying the exponent you would have:
30.25+x2=144
Now you would simplify each side
X2=4.33
And then cancel out the 2
Then you would get your answer

Which table represents a linear function?


At a glance, Kendra believes that the function represented on the graph is linear.

How can Kendra determine if the function is actually linear?

She can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
She can check to see if the sum of each y-value and x-value in every ordered pair is the same.
She can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

A Rectangular has area 12a^2 and perimeter 14a what are the dimensions of this Rectangular?​

Answers

9514 1404 393

Answer:

  3a by 4a

Step-by-step explanation:

For dimensions L and W, the area and perimeter are ...

  A = LW = 12a^2

  P = 2(L+W) = 14a

Using the second equation, we can find L:

  L +W = 7a . . . . . divide by 2

  L = 7a -W

Substituting into the area formula gives the quadratic ...

  (7a -W)(W) = 12a^2

  W^2 -7aW +12a^2 = 0 . . . . arrange in standard form

  (W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)

Then we have the two solutions ...

  W = 3a, L = 4a

  W = 4a, L = 3a

The rectangle dimensions are 3a by 4a.

Gavin rolls a fair dice 30 times.
How many times would Gavin expect to roll a five?

Answers

The expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total outcomes = {1, 2, 3, 4, 5, 6]

Total number of outcomes = 6

Favourable outcomes = {5}

Total number of favourable outcomes = 1

Probability of rolling 5 = 1/6

The expected number of 5's would be 30×(1/6) =  5 times

Thus, the expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

Y varies directly as X and inversely as the square of Z. Y=30 when X=75 and Z=5. Find Y when X=36 and Z=2

Answers

Answer:

Y  when X=36 and Z=2 is 90

Step-by-step explanation:

Given -

Y varies directly as X and inversely as the square of Z

[tex]y = \frac{kx}{z^2}\\30 = \frac{k *75}{5^2} \\30 = 75k/25[/tex]

[tex]k = 10[/tex]

As we know

[tex]y = \frac{kx}{z^2}[/tex]

Substituting value of X = 36 and Z = 2 in above equation, we get -

[tex]y = \frac{10*36}{2*2} \\y = 90[/tex]

The slope is -2/3.

The equation of the line is

y = -2/3 x + 3

The line is dashed, not solid, and the shading is above the line, so the inequality is

Answer:

y = 7

Step-by-step explanation:

Mathematically, according to the Pythagoras’ theorem;

The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides

The hypotenuse is the side that faces the right angle and it is represented by the square root of 85 here

Thus, we have it that;

(√85 )^2= 6^2 + y^2

85 = 36 + y^2

y^2 = 85-36

y^2 = 49

y = √49

y = 7
