We have to find the number of significant figures in the product of 1.6 cm and 2.4 cm.
Let us first find the product of 1.6 cm and 2.4 cm.
= 3.84 square cm.
Now, we have to determine the number of significant figures in 3.84
The significant digits of a number are the digits have meaning or they contribute to the value of the number. All non-zero digits are significant
, any zeros between significant digits are also significant figures and the trailing zeros to the right of a decimal point are significant figures.
Therefore, in 3.84, there are 3 significant figures in this number.
So, there are 3 significant figures in the product of 1.6 cm and 2.4 cm.
Based off of the equation, the road was 59 miles to start with. Because x represents the number of days working, and it is being multiplied by 4, the crew is changing the road by 4 miles a day.
Answer:
The answer to your question is ∠B = 47, ∠F = 69, ∠H = 62, ∠K = 51
Step-by-step explanation:
To find the values of the angles, use the theorem that states that the sum of the internal angles in a triangle equals 180°.
-Find A
∠A + ∠B + ∠C = 180°
82 + ∠B + 51 = 180°
∠B = 180 - 82 - 51
∠B = 47°
-Find F
∠E + ∠F + ∠D = 180
49 + ∠F + 62 = 180
∠F = 180 - 49 - 62
∠F = 69°
-Find H
∠G + ∠H + ∠I = 180
∠H = 180 - 49 - 69
∠H = 62°
-Find K
∠J + ∠K + ∠L = 180°
82 + ∠K + 47 = 180°
∠K = 180 -82 - 47
∠K = 51°
15/45 = x/60
* Cross multiply and solve for x
x=20
Check the complete question attached.
We have the equation
equation (1); solving for F we get:
equation (2)
I. To check this we are going to use equation (1) to see what hapen when temperature rises from 32 Fahrenheit to 33 Fahrenheit:
For 32 Fahrenheit:
For 33 Fahrenheit:
Now we are going to subtract the two temperatures in degrees Celsius:
As you can see, the temperature increased
degree Celsius.
We can conclude that a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
degree Celsius.
II. To check this one we are going to use equation (2) to see what happens when temperature raises from 1 degree Celsius to 2 degrees Celsius:
For 1 degree Celsius:
For 2 degrees Celsius:
Now we are going to subtract the two temperatures in Fahrenheit:
As you can see, the temperature increased 1.8 Fahrenheit.
We can conclude that a temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 Fahrenheit.
III. Since a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
degree Celsius, we can conclude that this one is false.
The correct answer is D) I and II only
