Answer: Her height in centimeters will be 460 cm.
Step-by-step explanation:
Since we have given that
Average height of a female giraffe = 4.6 meters
As we know that
So, we need to convert 4.6 meters into centimeters.
And we know that meters is more than centimeters so, we use the product operation.
So, her height in centimeters will be 460 cm.
The average height of a female giraffe in centimetres is 460 cm.
Given:
The average height is 4.6 meters (m). What is its height in centimeters? So, in this problem, we are going to convert meters (m) to centimeters (cm)
As we know that :
so to convert meter to centimeter, just multiply it with 100 cm
There is another way to do it, in three step:
We can cancel the meter (m) because it is both on top and the bottom

Answer:
b.
Sacramento School has 1650 students
Ronald E School has 1800 students
c.
Apple Pies cost $4 each
Black Berry Pies cost $19 each
Step-by-step explanation:
b.
Let "x" students attend Sacramento School, and
"y" students attend Ronald E. School
It is given that Sacramento School has 150 fewer students than Ronald E School, so we can write:
x + 150 = y
And,
Total number of students in 2 schools is 3450, we can write:
x + y = 3450
We put Equation 1 in Equation 2 and solve for x first:
Now, we know y = x + 150, y = 1650 + 150 = 1800
So, Sacramento School has 1650 students
Ronald E School has 1800 students
c.
Let apple pies cost "x" and blackberry pies cost "y" each
Gabriella sold 10 apples pies and 12 blackberry pies for total 268, so we can write:
10x + 12y = 268
Also,
Mary sold 14 apple pies and 4 blackberry pies for 132, so we can write:
14x + 4y = 132
Let's multiply Equation 2 with -3, to get:
-3 [14x + 4y = 132]
= -42x - 12y = 396
Lets add this equation to equation 1:
10x + 12y = 268
-42x - 12y = -396
------------------------
-32x = -128
x = -128/-32
x = 4
Now, plugging in x = 4 into 1sst equation, we can solve for y:
10x + 12y = 268
10(4) + 12y = 268
40 + 12y = 268
12 y = 228
y = 228/12
y = 19
So,
Apple Pies cost $4 each
Black Berry Pies cost $19 each
No the two expressions (12 + 6) ÷ 2 and 12 + 6 ÷ 2 will not have the same answer.
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The value of the two expressions will be calculated by using the concept of BODMAS as follows:-
( 12 + 6 ) ÷ 2 = 18 ÷ 2 = 9
12 + ( 6 ÷ 2 ) = 12 + 3 = 15
Therefore the two expressions (12 + 6) ÷ 2 and 12 + 6 ÷ 2 will not have the same answer.
