Answer:
<em>The actual width of the hair is 20 / 150 = 0.13 mm</em>
Step-by-step explanation:
<u>Scaling</u>
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.
The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.
The hair can be seen 2 cm wide in the photograph.
Converting to millimeters, 2 cm = 2*10 = 20 millimeters.
The actual width of the hair is 20 / 150 = 0.13 mm
Answer:
<u>For 1 quart of orange juice:</u>
Calories = 448
Vitamin C = 387.6 mg
Carbohydrates = 107.56 mg
Step-by-step explanation:
The following information is given about 1 CUP of orange juice:
<h2>Calories</h2><h3>112</h3><h2>Vitamin C</h2><h3>96.9 mg</h3><h2>Carbohydrates</h2><h3>26.89 mg</h3>
Now, we have to estimate the 3 values for 1 quart of orange juice. Remember, 4 cups is 1 quart, so we need to multiply each value by 4 to get the values for 1 quart.
Calories = 112 * 4 = 448
Vitamin C = 96.9 * 4 = 387.6 mg
Carbohydrates = 26.89 * 4 = 107.56 mg
Answer:
I think the answer is Y>-2
Answer:
b=7
Step-by-step explanation:
3-5b=-32
-5b=-32-3
-5b=-35
Divide both sides by -5
b=7
<h3>Given :-</h3>


<h3>To find:</h3>


<h3>Solution:-</h3>
Let say it is first equation:-
x=y-1. . . . (1)
and this is second equation:-
x+2y=8 . . . . (2)

Simplifying 1 equation:-
- x = y - 1
- x +1 = y
- y = x + 1
Put this value of y in second equation.

















to find value of y :-
y = x + 1
y = 2 + 1
y = 3

verification:-

1 equation:-
x = y - 1
put value of x and y
2 = 3 - 1
2 = 2
LHS = RHS
Hence verified!

2 equation:-

put value of x and y
- 2 + 2 × 3 = 8
- 2 + 6 = 8
- 8 = 8
LHS = RHS
Hence verified!

Both equation verified!
.°. value of x and y is 2 and 3 respectively
