Answer:

1) option 1

2) 191 students

3) 420 people

4) 16

Step-by-step explanation:

n(Baseball & Basketball) = x

30 = 18 + 17 - x

30 = 35 - x

x = 35 - 30

x = 5

Only basketball: 17 - 5 = 12

Only baseball: 18 - 5 = 13

2) 464 - (89 + 215 - 31)

464 - 273

192

3) 630 - 210 = 420

4) 40 - 15 - 9 = 16

Answer:

1) ven diagram #1

2)160

3) 420

4)16

Step-by-step explanation:

1) lets make a ratio table:

(look at image below, sorry for the horrible writing)

the original ratios are 18 and 17, and 18+17=35   35 is the number of students who play either or both sports. 30 is the number who play either sport:

so 35-30=5

5 students play both sports:

18-5=13(baseball)

17-5=12(basketball)

2) add up all the students who do band or sports and subtract from the total number of students

so

89/464+215/464= 304/464 students play in band or orchestra or both, to find the number of students who dont:

464-304=160

3) 630/1000+420/1000=1050/1000

1050/1000-210/1000=840/1000

840/1000-420/100=420/1000

420 ppl use brand p

4) 15+9=24

40-24=16

16 ppl

hope this helps!

2y + 12 = -3x<br><br> solve pls i have more I WILL GIVE EXTRA POINTS!!!!!!!!!!<br> 20+
Mrac [35]

2y + 12 = -3x

Step-by-step explanation:

Divide y y by 1 1 . Divide 12 12 by 2 2 . Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.

The figure shown below is composed of a semicircle and a non-overlapping equilateral triangle and contains a hole that is also c
Sloan [31]

Check the picture below.

since we know the radius of the larger semicircle is 8, thus its diameter is 16, which is the length of one side of the equilateral triangle.  We also know the smaller semicircle has a radius of 1/3, and thus a diameter of 2/3, namely the lenght of one side of the small equilateral triangle.

now, if we just can get the area of the larger figure and the area of the smaller one and subtract the smaller from the larger, we'll be in effect making a hole/gap in the larger and what's leftover is the shaded figure.

\bf \stackrel{\textit{area of a semi-circle}}{A=\cfrac{1}{2}\pi r^2\qquad r=radius}~\hspace{10em}\stackrel{\textit{area of an equilateral triangle}}{A=\cfrac{s^2\sqrt{3}}{4}\qquad s=\stackrel{side's}{length}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\Large Areas}}{\left[ \stackrel{\textit{larger figure}}{\cfrac{1}{2}\pi 8^2~~+~~\cfrac{16^2\sqrt{3}}{4}} \right]\qquad -\qquad \left[ \cfrac{1}{2}\pi \left( \cfrac{1}{3} \right)^2 +\cfrac{\left( \frac{2}{3} \right)^2\sqrt{3}}{4}\right]}

\bf \left[ 32\pi +64\sqrt{3} \right]\qquad -\qquad \left[ \cfrac{\pi }{18}+\cfrac{\frac{4}{9}\sqrt{3}}{4} \right] \\\\\\ \left[ 32\pi +64\sqrt{3} \right]\qquad -\qquad \left[ \cfrac{\pi }{18}+\cfrac{\sqrt{3}}{9} \right]~~\approx~~ 211.38 - 0.37~~\approx~~ 211.01

Write this in standard form y+2=-3/4(x+1) that -3/4 is a fraction plz show work!!
pentagon [3]
Y+2=-3/4(x+1)
y+2=-3x/4 -3/4
y=-3x/4 - 3/4 - 2
y = -3x/4 - 3/4 - 8/4
y = -3x/4 - 11/4

A light bulb consumes
Dmitry [639]
We know that 5 days and 12 hours is as much as 5.5 days, so all we need to do is to multiply 1800 watt-hours by 5.5 days:

1800 * 5.5 = 9900

Answer: <u>A light bulb consumes 9900 watt-hours each 5 days and 12 hours</u>.
