Answer:
The length of side is 42.4 inches.
Step-by-step explanation:
Given that:
Diagonal of square = 60 inches
As all sides of a square are equal, thus
Side of square = x
The diagonal will be the hypotenuse of a right angled triangle.
Using Pythagorean theorem;

Taking square root on both sides

Hence,
The length of side is 42.4 inches.
Answer:
i think x=-1 and y=3. ....
Answer:
482.5 ft^2.
Step-by-step explanation:
The figure can be regarded as a rectangle with a triangle cut out of one corner.
The base of the triangle = 25-20 = 5 in and the height = 20 - 13 = 7 in.
The required area = area of rectangle - area of triangle
= 25*20 - 1/2 * 5 * 7
= 500 - 17.5
= 482.5 ft^2
1 basket is between 9 and 10 minutes .
<u>Step-by-step explanation:</u>
Here we have , John kept track of how many baskets were made in a basketball game. After 4 minutes, 5 baskets were made. We need to find How many baskets were made between 9 and 10 minutes . Let's find out:
In order to calculate baskets between 9 min and 10 min we will find baskets at 10 min and at at 9 min , will subtract than !
Baskets at 10 min :
At 4 min we have 5 baskets so , in 10 min
⇒ 
⇒ 
⇒ 
Baskets at 9 min :
At 4 min we have 5 baskets so , in 9 min
⇒ 
⇒ 
⇒ 
So , Baskets between 10 & 9 min is
, which on rounding off gives 1 . Therefore , 1 basket is between 9 and 10 minutes .
Answer:
a. 7.2
b. 6
Step-by-step explanation:
Since the side lengths of similar polygons are proportional to each other, therefore:

Thus, let's find b using:

Cross multiply


Divide both sides by 15
b = 6
Let's find a using:

Cross multiply
9*12 = 15*a
108 = 15a
Divide both sides by 15
a = 7.2
