What is the total number of students in Holly@s school?
The sum of 130 cm and 50 mm. in meters is 1.35 m.
The unitarymethod is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. The unitary method is a method by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.
We are given the sum of 130 cm and 50 mm. in meters
130 cm = 130 / 100
= 1,3m
50 mm = 50 / 1000
= 0,05m
Therefore, the addition is;
1.3 + 0.05m = 1.35m

= 11(6)
=66
Solution:
Given that,
Laura wrote and solved the following expression to find the total number of beads Lina has
There are 6 beads in each packet
7+4b = 11b
= 11(6)
=66
From given,
Lina has a total of 7 + 4b beads
Given that, There are 6 beads in each packet
Substitute b = 6
7 + 4(6)
Simplify
7 + 24
Add
31
Thus, she has a total of 31 beads and not 66 beads
Laura made a mistake by adding the constant 7 and variable 4b
But a constant and variable cannot be added
Answer:
ya foot
Step-by-step explanation:
Answer: 20 ft
Step-by-step explanation:
Given: The length of rope tied to the top of a flag pole=29 ft
The distance between base of the pole and the point on ground where the rope is stacked= 21 ft
Let x be the height of flagpole.
Now, we can see the figure that the given situation represents a right triangle
Where longest side= 29
By Pythagoras theorem of right triangle, the square of the longest side is equal to the sum of the squares of the other two sides.
Hence, the height of flagpole = 20 ft.
