Step-by-step explanation:
Let the number with two decimal places be 1.23
Let the number with one decimal place be 4.5
Then 1.23 multiplied by 4.5
= 1.23 × 4.5
= 5.535
The result has more than two nonzero digits.
Note: When you multiply two decimal numbers, the decimal place(s) of the result is the addition of the decimal places of each of the numbers being multiplied.
An expression represents the perimeter, in centimeters, of this triangle is 6q + 8r - 5s.
<u>Given the following data:</u>
- b = (5q - 10s) centimeters.
- c = (5s + 7r) centimeters.
<h3>What is a triangle?</h3>
A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.
<h3>How to calculate the perimeter of a triangle?</h3>
Mathematically, the perimeter of a triangle can be calculated by using this formula:
P = a + b + c
<u>Where:</u>
a, b, and c are length of sides.
Substituting the given parameters into the formula, we have;
P = q + r + 5q - 10s + 5s + 7r
P = 6q + 8r - 5s centimeters.

Let's assume the number be x.
So, sum of a number and 10 can be written as x+10.
Now the given statement is "One half of the sum of a number and 10 ".
So, one half of x+10 can be written as
Answer:
12.686cm
Step-by-step explanation:
By using pythagoras, we can find CB.
We know that
Therefore,
(it has to be positive since it is distance)
now we look at triangle BCD and use SOH CAH TOA.
