There are 12 girls and 16 boys . What is the largest number in each group?
lianna [129]

Answer:

Step-by-step explanation:

The largest number of groups they can be split into and have the same number of boys and girls on each team is 6 groups

Given:

Number of girls = 12

Number of boys = 16

Find the highest common factor of 12 and 16

12 = 1, 2, 4

18 = 1, 2,4

The highest common factor of 12 and 16 is 4

Number of girls in each group = 12/4

= 3 girls

Number of boy in each group = 18/4

= 4.5 boys=5

Therefore, the group can be split into 4 groups to have 3 girls and 5 boys in each group

This graph relates the volumes of triangular pyramids with a base area of 12 square inches and their heights.
Nikolay [14]

Answer:

V=40\ in^3

Step-by-step explanation:

The graph is not attached, however we know that, the volume of a triangular pyramid is given by the formula

V=\frac{1}{3}Bh

where

B is the area of the triangular face

h is the height of the pyramid

we have

B=12\ in^2\\h=10\ in

substitute the given values

V=\frac{1}{3}(12)(10)=40\ in^3

If a bus travels 20 km in 30 minutes. What is the average speed of the bus?
sattari [20]
<span>So we need to find the average speed of the bus that travels 20 km in 30 minutes. Average speed is defined as: Average speed=distance travelled/time taken or: v=s/t. We know s=20 km and t=30 minutes=0.5h. So after we input our numbers in the equation, we get: v=20km/0.5h=40km/h. So the correct answer is C) 40km/h.</span>
