Answer:

18 students is the amount that passed the test

so the fraction would be 18/24, which can be simplified to 3/4, which is 75% of the class.

75% of the class passed

0.75% of the class passed

What is the volume of a pyramid whose base is a square of area 36 and whose four faces are equilateral triangles?
irina1246 [14]

Answer:

V = 36\sqrt{2}

Step-by-step explanation:

The volume of a pyramid is

V = \dfrac{1}{3}Bh

where B = area of the base, and h = height of the pyramid

The base is a square.

A = s^2

s = \sqrt{A}

s = \sqrt{36}

s = 6

The side of the base has length 6. Each face of the pyramid is an equilateral triangle with side of length 6.

An altitude of this triangle measures

a = \sqrt{6^2 - 3^2}

a = \sqrt{27}

The pyramid is formed by 4 equilateral triangles whose bases form a square. The tips of the faces meet at a single point on top. The vertical distance from that point to the center of the base is the height of the pyramid.

h = \sqrt{(\sqrt{27})^2 - 3^2 }

h = \sqrt{27 - 9}

h = \sqrt{18}

h = 3 \sqrt{2}

Volume of the pyramid:

V = \dfrac{1}{3}Bh

V = \dfrac{1}{3}(36)(3\sqrt{2})

V = 36\sqrt{2}

Coffee costs $12 per case and tea cost $8 per case. If an order comes in for 250 cases for a total of $2,600 how many cases of c
Harlamova29_29 [7]
Coffee = $12
Tea = $8
Total cost = $2600
Total Case = 250

Assumed all 250 cases are Tea
250 x 8 = 2000

Difference in amount
2600 - 2000 = 600 (so $600 was from the coffee)

Difference between the price of coffee and tea
12 - 8 = $4

Number of cases of coffee
600 ÷ 4 = 150 

Number of cases of tea
250 - 150 = 100

150 cases of coffee were ordered

In places where there are crickets, the outdoor temperature can be predicted by the rate at which crickets chirp. One equation t
irina1246 [14]

Answer:

See explanation

Step-by-step explanation:

This question requires a list of options.

Since, there are none; I'll give a general explanation to answer this.

We have that:

f = 14c + 40

The general format of an equation in terms of f and c is:

f = mc + b

Where

m = slope and b = y\ intercept

A true statement about the function above is:

The slope of the equation is 14

This means that at every minute, there's an additional 14 chirps from the cricket.

Another true statement about the function is that:

The y intercept is 40.

This means that the initial number of chirps by the cricket is 40

i.e. At time, c = 0 minutes.

There are 40 chirps.

A likely question could be to determine the number of chirps in (say) 5 minutes.

This means that:

c= 5

Substitute 5 for c in f = 14c + 40

f = 14 * 5 + 40

f = 70 + 40

f = 110

This implies there are 110 chirps in 5 minutes
