Length of the side = 9 cm
Diagonal = 
cm
Solution:
Area of the square = 81 square centimeters
In square all sides are equal.
Area of the square = side × side
Side × side = 81
Side² = 9² (∵81 = 9²)
Taking square root on both sides, we get
Side = 9 cm
Length of the side = 9 cm
To find the length of the diagonal:
In square all the angles are right angle.
Diagonal splits the square into two right angle triangle.
Using Pythagoras theorem,
<em>In right triangle, square of the hypotenuse is equal to the sum of the square of the other two sides.</em>
Here, diagonal is the hypotenuse.
Taking square root on both side,
Diagonal = cm
Answer:
65
Step-by-step explanation:
Time taken by the car to cover 260 km is 2.6 hrs
Step-by-step explanation:
- Step 1: Find the speed of the car given distance covered = 150 km and time = 1.5 hrs.
Speed = Distance/Time = 150/1.5 = 100 km/hr
- Step 2: Find the time taken by the car to cover 260 km.
Time = Distance/Speed = 260/100 = 2.6 hrs
Answer:
a) 4 quarts of sparkling water
b) 38.5 quarts of grape juice
c) 80 quarts of sparkling water and 20 quarts of grape juice
The answers for the letters in the chart are on the bottom for b and c.
Step-by-step explanation:
a) You would need 4 quarts of sparkling water for 1 quart of grape juice.
This proportion is to get the amount of grape juice you need you multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
So for a) I know that .25 of a quart of grape juice is equal to 1 quart of sparkling water. So to get the amount of sparkling water multiply the amount of grape juice you need by .25. And the number you multiplied .25 will be the amount of sparkling water you need. Example: <u>4</u> × .25 = 1 quart of grape juice.
4 is the amount of sparkling water you need.
b) For b you just need to multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
154 × .25 = 38.5
You need 38.5 quarts of grape juice.
c) You would need 80 quarts of sparkling water and 20 quarts of grape juice.
80 × .25 = 20
b on the graph is 38.5 because 154 × .25 = 38.5
c on the graph is 400 because .25 × 400 = 100
HOpe this helps ya!!
