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
If you want to evaluate what percent of 550 is 4, you can do this in two following steps.<span>
<span>First, you have to write it as a fraction: 4</span>/550.
Second, you have to transform this fraction to
percent: (4/550)*100%.
(4/550)*100% = 0.0072727272727273*100% =
0.727%
<span>The correct result is </span>0.727%.</span>
Answer:
The two numbers are 24 and 32
Step-by-step explanation:
We can use the variable x
3x : 4x, would be a ratio of 3/4
now subtract 4 from both
3x - 4 : 4x - 4 = 5/7
3x-4 / 4x-4 = 5/7
cross multiplication
7(3x - 4) = 5(4x - 4)
21x - 28 = 20x - 20
x = 8
Two numbers are;
3x, 4x
3(8), 4(8)
24, 32
24/32 = 3/4
20/28 = 5/7
Answer:(x+5i) (x-5i) is the right answer
