Answer:
7
40
the answer is 7 fortyths
working out
3 quarters - 3 eighths = 3 eighths*7 nineths= 7 twentyforths
5 sixths +1 third + 1 half = 10 sixths
7 twentyforths divided by 10 sixths= 7 fortyths
Answer:
cosФ is ⇒ B
Step-by-step explanation:
Let us solve the question using one of the identities of trigonometry
∵ sin²Ф + cos²Ф = 1
∵ sinФ =
→ Substitute it in the rule above to find cos Ф
∴ ()² + cosФ² = 1
∴ + cosФ² = 1
→ Subtract from both sides
∴ cos²Ф =
→ Take √ for both sides
∴ cosФ = ±
∵ Angle Ф lies on the second quadrant
∴ cosФ is a negative value
∴ cosФ =
∴ cosФ is
Answer:
I used a little bit of the question i am on Right Now but the answer is in there somewhere
Step-by-step explanation:
ratio for boys: 3 soccer/5 basketball
ratio for girls: 7 soccer/1 basketball (I think you have a typo when you say "...number of boys who enjoyed basketball
of 7:1" because boys and girls were surveyed separately.)
that said...
90 boys enjoy soccer
3*30/5*30=90 boys enjoy soccer/150 boys enjoy basketball
90+150=240 boys and therefore 240 girls
7/1 is the ratio for girls
7+1=8, 240/8=30
7*30/1*30=210 girls enjoy soccer/30 girls enjoy basketball (210+30=240)
