Mr. Keen, a band teacher, wanted to know if certain types of instruments are more appealing to one gender or the other. So, he conducted a survey of his students’ preferences. The results are compiled in the chart below: Instruments
Boys
Girls
Strings Woodwind Brass Percussion
15 23
19 30
27 13
32 25
Part A
What is the ratio of the number of girls preferring woodwind instruments to the number of boys preferring woodwind instruments?
A. 23:30 B. 30:19 C. 19:30 D. 4:5
Part B
What is the ratio of the number of boys preferring percussion instruments to the total number of boys who were surveyed?
A. 32:25 B. 25:32 C. 93:32 D. 32:93
Part C
What is the ratio of the number of girls preferring strings to the total number of students preferring strings?
A. 23:38
B. 38:23
C. 32:91
D. 91:32 is

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
