It is already given in the question that that freezing temperature of water is 0 degree Celsius. The freezing temperature of water in degree Fahrenheit is required to be found.
We know the relation between degree centigrade and degree Fahrenheit is"
Degree Fahrenheit = C(9/5) + 32
Here in the above equation "C" represents degree centigrade.
From the question we already know the freezing temperature of water as 0 degree Centigrade. Now we have to replace the value of Centigrade in the equation
Degree Fahrenheit = C(9/5) + 32
= 0(9/5) + 32
= 0 + 32
= 32 degrees
So water freezes at 32 degrees Fahrenheit.
Answer:
12 fives and 18 tens
Step-by-step explanation:
solving this we need 2 different equations
one for he total bills and one for the total money
x+y=30
that is total bills
5x+10y=240
combining both equations we can use elimination method and get
12 five dollar bills and 18 ten dollar bills
Answer:
E
Step-by-step explanation:
I don't understand in this specific context what is evaluated means but looking over the options it seems that 0 to the negative 1/2 power seems pretty unlikely . the only reason I don't say 0 to the negative 2nd power is because 0 to the negative 2nd power seems plausible but it doesn't seem like 0 to the negative 1/2 power would ever become a thing
Question 7: Option 1: x = 33.5°
Question 8: Option 3: x = 14.0°
Step-by-step explanation:
<u>Question 7:</u>
In the given figure, the value of perpendicular and hypotenuse is given, so we have to use any trigonometric ratio to find the value of angle as the given triangle is a right-angled triangle
So,
Perpendicular = P = 32
Hypotenuse = H = 58
So,
Rounding off to nearest tenth
x = 33.5°
<u>Question 8:</u>
In the given figure, the value of Base and Perpendicular is given, we will use tangent trigonometric ratio to find the value of x
So,
Perpendicular = P = 5
Base = B = 20
So,
Rounding off to nearest tenth
x = 14.0°
