Joseph Nicéphore Niépce

The world's first photograph made in a camera was taken in 1826 by Joseph Nicéphore Niépce. The photograph was taken from the upstairs windows of Niépce's estate in the Burgundy region of France.

8 hours

The first photograph ever shot, the 1826 photo View from the Window at Le Gras, took a whopping 8 hours to expose. When Louis Daguerre introduced the daguerreotype in 1839, he managed to shave this time down to just 15 minutes.

Center City East Parking Garage has a capacity of 257 cars more than Center City West Parking Garage. If the combined capacity f

amid [387]

Center City West = x
Center City East = (x + 257)

Solve for x to find the capacity for Center City West and then we can find the capacity for Center City East.

(x + 257) + x = 1221
x + x + 257 = 1221
2x + 257 - 257 = 1221 - 257
2x = 964
2x / 2 = 964 / 2
x = 482
Center City West capacity = 482

Now to find Center City East capacity we substitute 482 for x in (x + 257)

(x + 257)
(482 + 257)
482 + 257 = 739

Center City East capacity = 739
Center City West capacity = 482

Please find the least common denominator for 3/8 5/12

andriy [413]

Answer:

Step-by-step explanation:

Given two fractions $\frac{3}{8}$ and $\frac{5}{12}.$

Factor the denominators of both fractions:

$8=2\cdot 4=2\cdot 2\cdot 2\\ \\12=2\cdot 6=2\cdot 2\cdot 3$

You can see that two digits 2 are the same in both denominators and there are two more factors: 2 in number 8 and 3 in number 12.

Thus, the least common denominator for $\frac{3}{8}$ and $\frac{5}{12}$ is

$2\cdot 2\cdot 2\cdot 3=24$

Pip, Angad and Nick share some sweets in the ratio 4:4:1. Pip gets 20 sweets. How many

Likurg_2 [28]

Answer:

Step-by-step explanation:

The 4 part of the ratio represents Pip's 20 sweets

Dividing 20 by 4 gives the value of one part of the ratio

20 ÷ 4 = 5 sweets ← value of 1 part of the ratio

Thus

Pip gets 20 sweets

Angad gets 20 sweets ( 4 parts of the ratio )

Nick gets 5 sweets ( 1 part of the ratio )

Total number of sweets = 20 + 20 + 5 = 45

Answer: 4(2x²+9) or $i\frac{3\sqrt{2} }{2}$

Step-by-step explanation:

To solve the equation by factoring, we want to set the equation to zero. In order to have the equation equal to zero, we want to add both sides by 36.

8x²=-36 [add both sides by 36]

8x²+36=0

When it comes to factoring, we want to pull out numbers or variables that are common in each term.

8x²+36=0 [take out a 4 in each term]

4(2x²+9)=0

It may seem that 2x²+9 can be factored further, it actually can't. This tells us that the factored form of the equation is 4(2x²+9)=0.

To solve the equation, we want to find the value of x. We already know the graph does not cross the x-axis because the y-intercept or vertex is (0,9).

4(2x²+9)=0 [divide both sides by 4]

2x²+9=0 [subtract both sides by 9]

2x²=-9 [divide both sides by 2]

x²=-9/2 [square root both sides]

$x=\sqrt{-\frac{9}{2} }$ or $x=i\frac{3\sqrt{2} }{2}$
