Answer: 4,5
Step-by-step explanation:
<span>3^4 ⋅ 3^−9
= 3^(4-9)
= 3^-5
= 1 / 3^5
= 1/243</span>
Answer:
x = 3
Step-by-step explanation:
Because the endpoints of the segment with length 12.5 are the midpoints of the sides of the large trapezoid, the length of that segments, 12.5, is the average of the lengths of the top and bottom lengths of the large trapezoid.
(3x + 1 + 15)/2 = 12.5
Multiply both sides by 2.
3x + 16 = 25
3x = 9
x = 3
Answer:
(i) Breadth = 14 cm
(ii) Perimeter = 176 cm
Step-by-step explanation:
Given,
- Area of a rectangle =
cm²
- Length =
cm
(i) Breadth = ?
We know that, Area of a rectangle = length × breadth.
Then,

(ii) Perimeter of a rectangle = 2 (length + breadth)
Then,


Answer:

Step-by-step explanation:
We are given the following in the question:
"A temperature in kelvin is 273.15 greater than the temperature in degrees Celsius."
We have to write an equation that relates temperature K in Kelvin to temperature C in Celsius.
According to the given relation, we can write the equation:

is the required equation that provides a relation between temperature in Kelvin and temperature i Celsius.
