Answer:
9 students on the committee are males
Step-by-step explanation:
As per the statement:
There are 15 students on a yearbook committee.
⇒Total students on a yearbook committee = 15
⇒
....[1]
It is given that:
40% of the students are females
⇒![\text{Female students} = \frac{40}{100} \cdot 15 = 6](https://tex.z-dn.net/?f=%5Ctext%7BFemale%20students%7D%20%3D%20%5Cfrac%7B40%7D%7B100%7D%20%5Ccdot%2015%20%3D%206)
Substitute in [1] we have;
![\text{Male students} + 6 = 15](https://tex.z-dn.net/?f=%5Ctext%7BMale%20students%7D%20%2B%206%20%3D%2015)
Subtract 6 from both sides we have;
![\text{Male students}= 9](https://tex.z-dn.net/?f=%5Ctext%7BMale%20students%7D%3D%209)
Therefore, 9 students on the committee are males
Answer:
577.50
Step-by-step explanation:
You need to add all the areas of the separate pieces together, so the triangles are:
Triangle: 7 (12) (1/2), but you have 2 of them so don't divide by 2, just 7(12) so that part is 84
Top flap is 15(7) = 105
Middle is 15(12) = 180
Bottom is 15(13.89) = 208.35
Add them all together 84+105+180+208.35 = 577.50
