Answer 1

Answer:

Answer: z=56

Step-by-step explanation:

Based on the figure, we can determine that 3y+8=68 and 4x=2z. With the knowledge that a trapezoid has 360°, we can first find the value of y to get the angle measures of the top angles. We can then subtract that from 360°.

3y+8=68 [subtract both sides by 8]

3y=60 [divide both sides by 3]

y=20

We now know the value of y is 20, but that is not relevant to solving this problem because we already know that the top angles are 68° each. So, we can subtract that from 360.

360-68-68=224

Now, we know that the bottom 2 angles have to add up to 224. Therefore, we can come up with 2 equations.

Equation 1: 4x=2z

Equation 2: 4x+2z=224

We can manipulate Equation 1 to be $x=(1)/(2)z$ . Once we plug that into Equation 2, we can find the value of z.

$4((1)/(2) z)+2z=224$ [multiply]

$2z+2z=224$ [add]

$4z=224$ [divide both sides by 4]

$z=56$

Now, we know that z=56.

Answer:

7/3x + 2/3 = 7/9x - 5/6

7/3x - 7/3x + 2/3 = 7/9x - 7/3x - 5/6 (7/9x-7/3x--->7/9x-21/9x---> -14/9x)

2/3= -14/9x - 5/6

2/3+5/6 = -14/9x - 5/6 + 5/6 - (2/3 + 5/6---> 4/6 + 5/6---> 9/6 ----> 3/2)

3/2 = -14/9x

3/2 / -14/9 = -14/9x / -14/9 - (3/2 / -14/9 ------> 3/2 x -9/14 ----->

- 27/28)

-27/28 = x

A human red blood cell is 7.5 micrometers in diameter.1 centimeter = 10,000 micrometers
What is the diameter in centimeters?

Answers

To solve this question, we do cross multiplication.

1 cm = 10,000 micrometers
7.5 micrometers.

? Cm = 7.5 micrometers X 1 centimetre/10000 micrometers.

? Cm = 0.00075 cm
So 7.5 micrometers = 0.00075 centimetres.
