Help please Can you clear fractions in an equation by multiplying each side by a common denominator other than the LCD? Give an

Katena32 [7]

Yes here is an example:_

x/4 + 5/6 = 2

The LCD of 4 and 6 is 12 but we can also multiply through by 24 to clear the fractions:-

x/4 * 24 + 5/6 * 24 = 2 + 24

6x + 20 = 40

This will give us the same result if we multiplied through by 12.

Please Help! Geometry!

OleMash [197]

Answer:

area = 22,272

Step-by-step explanation:

area = length * width

to calculate the width, we need the first segment using the pythagorean theorem

$87^{2} + x^{2} = 145^{2}$

$7569 + x^{2} = 21025$

$x^{2} = 13456$

$x = 116$

length = 116 + 140 = 256

area = 87 * 256 = 22,272

Một ủy ban an toàn kiểm tra ngẫu nhiên 900 công nhân xây dựng trong thời gian làm việc, thấy có 48 công nhân không mang mũ bảo h

Usimov [2.4K]

Answer:

The percentage of workers not wearing the helmets is 5.3 %.

Step-by-step explanation:

A safety committee randomly examined 900 construction workers during their work, and found that 48 workers were not wearing helmets. Estimate the percentage of workers who do not wear protective masks during their working time with 98% confidence

total workers = 900

Not wearing helmet = 48

Percentage which are not wearing the helmets

= $\frac{48}{900}\times 100 = 5.3 %$ %

Use the Pythagorean Theorem to find the distance of the missing side. (I’m sorry I need help with the whole thing)

Maurinko [17]

Answer:

1: 5.83

2: 4.12

3: 3.61

4: 5

5: 6.32

6: 5.10

Step-by-step explanation:

The Pythagorean theorem is a^2 + b^2 = c^2

For all of these you can count the number of blocks over to find two sides of the triangle.

For example: the first one has two sides, one is 3 units, the other is 5. To find the missing angle you square 3 and 5, then add that together. That is equal to 34. 34 = c^2. To get the c by itself, you then take the square root of 34. So the missing side (c) is equal to 5.83.
