Answer:
33 °C
Step-by-step explanation:
The bigger number is the <em>maximum</em> temperature.
Let’s call it T₂.
Then T₂ = 31 °C
=====
The smaller number is the <em>minimum</em> temperature
Let’s call it T₁.
Then T₁ = -2 °C
=====
The difference be the maximum and minimum temperature is
Diff = T₂ -T₁ Insert the values
Diff = 31 – (-2)
When you see a minus sign followed by a negative sign, turn them both into plus signs.
Then
Diff = 31 + (+2)
Diff = 31 + 2
Diff = 33 °C
Answer:
x = 8
Step-by-step explanation:
If a triangle is equilateral, each vertex has an angle that is equal to 60 degrees
As we can see, we have two sets of similar right triangles
The value x faces the right angle and that makes it the hypotenuse
Also, the side measure 4 is the adjacent side to the angle 60
The trigonometric identity that relates the hypotenuse and the adjacent is the cosine
it is the ratio of the adjacent to the hypotenuse
Mathematically;
cos 60 = 4/x
x = 4/cos 60
x = 8
99 ÷ 3 = 33 so each box weighs 33lbs or pounds each
so 33 × 4 = 132 pounds
or
99 + 33 = 132 pounds
