Raymond needs to cover the entire surface area of the square based pyramid with paper what is the minimum amount of paper he wil
ra1l [238]

Answer: 408 sq ft

Step-by-step explanation: You would need to use the surface area formula SA = 1/2LP + B. Note that L is the slant height, P is the perimeter of the base, and B is the area of the base. 11 is the slant height as shown in the image above, p is 48 since you add 12 + 12 + 12 + 12, and the area of the square will be 144 since 12*12 = 144. Once you substitute the numbers in their correct place, you should get SA = 1/2 (11)(48)+144 which gives you 408 sq ft. Hope this helps!

IRINA_888 [86]
I'll start by expanding everything, and 10^(x) means we move the decimal x places to the right. If we move the decimal to the right but there's no number there, that number is 0.
The populations are as follows (in the order in the graph) -
127,180,000
200,000,000
80,619,000
63,708,000
173,615,000
152,510,000

The first difference is the number of digits. The more, the better. The two that stand out at the bottom are Germany and the UK. Next, we look at the leftmost number. Since 6<8, Germany's population > UK's population. All other countries are greater than Germany. Next, we look at the next smallest amount of digits, which is every other country. We look at the first number, which gives us Japan, Nigeria and Bangladesh. Next, we look at the second number, and since 2<5<7, Japan is smaller than Bangladesh and Nigeria is bigger than Bangladesh. Our current list is as follows:
United Kingdom (UK), Germany, Japan, Bangladesh, Nigeria. Since Brazil 
has been proven to be greater than the rest (as it has more digits and 2>1), our list is now 
United Kingdom (UK), Germany, Japan, Bangladesh, Nigeria, Brazil

Y-80x=65 in function notation
kolezko [41]

Answer:f(x) = 80x + 65f


Step-by-step explanation:

Since x = days and y = total rent, you've been given two points on your function: (5, 465) and (7, 625). We'll find the slope using those two points:

(625 - 465) / (7 - 5) = 160/2 = 80

Then, use m = 80 and one of the points to write the equation of your line in point-slope form:

y - y1 = m(x - x1)

y - 465 = 80(x - 5)

Convert that to standard form:

y = 80(x - 5) + 465

y = 80x - 400 + 465

y = 80x + 65

y - 80x = 65

In function notation, that's:

f(x) = 80x + 65

Anastasy [175]

Answer:

Test statistic (t) = 0.625

Step-by-step explanation:

<u><em>Step(i):-</em></u>

mean of the Population(μ) = 10.4 hours

Sample mean (x⁻) = 10.7 hours

Standard deviation of the sample( S)  = 1.44

The level of significance (α= 0.1

Sample size 'n' = 9

Degrees of freedom = n-1 = 9-1 =8

<u><em>Step(ii)</em></u>:-

Test statistic

                     t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }

                   t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } }  =0.625
