Answer:
84 cm³
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
__
The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...
A = 1/2bh
A = 1/2(8 cm)(7 cm) = 28 cm²
Then the volume of the triangular pyramid is ...
V = 1/3(28 cm²)(9 cm) = 84 cm³
78
because 5 times 2 equals 10 so then u times 39 times 2 and get 78
Answer:
The ratio of blue balloons to the total number of balloons is 1:2.
Step-by-step explanation:
Given:
Total number of balloons = 14
Number of red balloons = 3
number of white balloons = 4
Number of the blue balloons are the rest remaining.
We need to find the the ratio of blue balloons to the total number of balloons.
Solution:
First we will find the number of blue balloons.
Now we know that;
Number of the blue balloons can be calculated by Total number of balloons minus sum of Number of red balloons and number of white balloons.
framing in equation form we get;
Number of the blue balloons = 
Now to find the ratio of blue balloons to the total number of balloons we will divide Number of the blue balloons from Total number of balloons.
framing in equation form we get;
Ratio = 
Hence the ratio of blue balloons to the total number of balloons is 1:2.
