Formula for triangle perimeter is: a + b + c. In this scenario we have:
a = 3 feet 8 inches
b = 2 feet 10 inches
c = 4 feet
a + b + c =
= 3 ft + 8 in + 2 ft + 10 in + 4 ft =
= 9 ft + 18 in
We know that 1 foot is 12 inches, so we can simplify the result to this form:
10 ft + 6 in
or:
<u>10.5 feet</u>
Let the number her brother has = x
She has 5 times as many so she has 5x
Together they have 42:
X + 5x = 42
Add x and 5x to get 6x:
6x =42
Divide both sides by 6:
X = 7
The brother has 7
Carla has 5*7 = 35
Answer: Carla has 35 notebooks
Answer:
⅛
Step-by-step explanation:
Each mark (x) on the plot presents the distance that each student jumped.
There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.
Number of students that jumped 5½ ft = 3
Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students
= 3/24
Simplify/reduce the fraction
= 1/8
A mixed number is rationtional as long as it isn't non repeating and it stops after a certain point.
