Answer:

-- Hamburgers got 33 total votes.

-- Tacos got 84 total votes.

-- Pizza got 82 total votes.

Tacos and pizza are almost equally preferred.

-- Tacos are out in front of pizza, but only by 2 votes.

-- Hamburgers are way behind, with less than half the votes of either tacos OR pizza.Step-by-step explanation:

OLga [1]

We have that the graph will have a solution that is mathematically given as

y=12sin(6t-\pi)+2

<h3>Daylight time June trough to December</h3>

Question Parameters:

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days).

Generally the equation for the Amplitude and vertical shift is mathematically given as

A=\frac{Max+min}{2}\\\\A=\frac{10+14}{2}

A=2

vertical shift =\frac{Max-min}{2}

vertical shift =\frac{14-10}{2}

vertical shift =1

Therefore, the time is given as

t=\frac{2\pi}{b}

Where

b=\pi/6\\\\t=\frac{2\pi}{\pi/6}

Hence,The graph will have a solution

y=12sin(6t-\pi)+2

What is the total surface area of the pyramid in square feet?
Elis [28]
Base is 12 feet square so 12 *12 = 144 square feet

each triangle has base of 12 feet and height of 8 feet
 area of triangle = 1/2 x base x height = 1/2 x 12 x 8 = 48 square feet

48 x 4 triangles = 192 square feet

total: 192 + 144 = 336 square feet

The side of the base of a square prism is decreasing at a rate of 7 kilometers per minute and the height of the prism is increas
Ber [7]

Answer:

dV = - 5.73*10⁹ m³/s

Step-by-step explanation:

Question: What is the rate of change of the volume of the prism at that instant (in cubic meters per second) ?

A function can be dependent on one or more variables. The change in the function due to a change in one o its variables is given by the functions derivative with respect to that variable. For functions that are composed of products of its variables, we may use the product rule to determine its derivative.

The volume of a square prism with base a and height h is given by

V = a²h

When the base and height are changing, we have

dV = 2ah(da/dt) +  a²(dh/dt)

Given

a = 4 Km

h = 9 Km

da/dt = - 7 Km/min

dh/dt = 10 Km/min

we have

dV = 2(4 Km)(9 Km)(- 7 Km/min) +  (4 Km)²(10 Km/min)

⇒   dV = - 504 Km³/min + 160 Km³/min = - 344 Km³/min

⇒   dV = - 5.73*10⁹ m³/s

Mrs. Bogaczyk got bored and decided to go on an Amazon spending spree! She bought 3 pairs of flip flops for $14.95 each, a sundr
Dovator [93]

Step-by-step explanation:

3 pairs of flip flops = 14.95 x 3 = 44.85

Total amount spent = 44.85 + 21.50 + 9.99 + 15. 44 = 91.78

After adding tax = 91.78 + 7.34 = 99.12

Mrs B spent 99.12 altogether

Budget = 100

Then money left = 100 - 99.12 = 0.88
