Divide the total amount of money Janice has by the cost of the stamps.
$7.20 / $0.30 = 24
Janice can buy 24 stamps.
Answer:
5 miles
Step-by-step explanation:
Think of this like a triangle. From the bottom of the tower, to the top of the tower, to the point 3 miles away, and back to the bottom of the tower.
So we already have 2 side lengths. The height of the tower, 3 miles, and the base, 4 miles. In order to find the 3rd length, the distance from the top of the tower to the point 4 miles away from the bottom, we need to apply the formula A squared + B squared = C squared.
We have A and B, (3 and 4) and we need C.
A squared (3 squared) is 9
B squared (4 squared) is 16
so 9 + 16 = C squared
9 + 16 = 25
C squared = 25
square root of 25 is 5
C = 5
The distance from the top of the tower to the point 4 miles away is 5.

Answer:
x=√14
Step-by-step explanation:
Hi there!
We are given a right triangle (notice the right angle), with acute angles measuring 45° and 45°, the hypotenuse (the side opposite from the right angle) labeled as x, and one of the legs (one of the sides that makes up the right angle) labeled as √7
As these two angles are the same measure, the triangle is isosceles.
So that means that the measure of the other leg (the unmarked side) is also √7.
This triangle is a special type of triangle; a 45°-45°-90° triangle. For this triangle, if the length of the legs are a, then the hypotenuse has the length a√2
In this case, √7 is a, and as x is the measure of the hypotenuse, it must be equal to a√2, which substituting the values of a would get √7 * √2, which is √14.
The radical cannot be simplified further, so √14 is the answer.
Hope this helps!
Answer:
70 students
Step-by-step explanation:
If 40% of all students in Mrs. Well's class got an A, and 28 students got an A, that means that 28 = 40%
To find the total number of students, we need to find 100%
40% = 28
Divide by 4
10% = 7
Multiply by 10
100% = 70
So there are 70 students in Mrs. Well's class.
Hope this helps you! :D
