The answer is 112. 4/10 of 280. 280 divided by 10 equals 28. 28 x 4 = 112
Answer:
100 or 60
Step-by-step explanation:
Since the question does not specify whether
refers to only the girls or all students, both will be calculated for your convenience.
If 2/3 refers to all students:
150*
=100
If 2/3 refers to the girls:
150*
*
=150*
=60
To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2
to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)
I hope this helps you

Isabella’s error is Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.
<h3>What is a cone?</h3>
It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.

Isabella equation:

The area of the base = 12π square cm

Thus, Isabella’s error is Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.
