Nadia surveyed 80 students at her school and found the following results:
=> 0.55 of the students she surveyed said their favorite class is math.
=> 15% of the students she surveyed reported that their favorite class is science.
Let's find out many more students in the survey prefer math over science?
MATH
=> 80 students * 0.55 = 44 students love math.
SCIENCE
=> 80 * .15 = 12 students love science
=> 44 - 12 = 32 students

B. 32

Al's Awesome Autos advertised a special sale on cars - Dealer cost plus 5%!! jack and Margaret bought a luxury sedan for $23,727.90.what was the dealers cost? please answer! it's for an important packet

Answers

Dealer's cost + 5% = 23,727.90

(1 + .05) dealer's cost = 23,727.90

Dealer's cost = 23.727.90 / 1.05 = 22,598

Tomas collected 139 cans for recycling on Monday and twice that number on Tuesday. How many cans did he collect on Tuesday

Answers

Answer: He collected 278 cans on Tuesday .

Step-by-step explanation:

We are given that Tomas collected 139 cans for recycling on Monday and twice ( 2 times) that number on Tuesday.

i.e. Number of cans collected for recycling on Monday =139

And Number of cans collected for recycling on Tuesday = $2*139$

Hence, the number of cans collected by him for recycling on Tuesday = 278

i.e. He collected 278 cans on Tuesday .

278 cans recycled on Tuesday

Can you please help find z?

Answers

Answer:

the angle for z° is 96°

Step-by-step explanation:

Since we already know 2 of the angles and that y=18° because both of the lines opposed to y are straight, so subtract all of what we know: 360-(64+18+18)=260°. x also has straight lines with the 64°, so subtract another 64°, then the equation will be 360°-(64+64+18+18), so z should equal 196, but there are 2 z angles, so divide it by 2 and the answer should be z°=96°

Answer this and add work, show all work for math. :P

Lines are in the form y=mx+b, where m is the slope and b is the y-intercept. This line is thus y=9/4x-14, so C is correct. Multiplying by four, we get 4y=9x-56. Adding 56 and subtracting 4y, we see that 9x-4y=56, and multiplying by -1, we get 4y-9x=-56, so A is also correct. At this point, it is clear that B and D are incorrect, so A and C only are correct.

You know that you can spot the slope and intercept right away
IF you 'solve' the equation for 'y'. Then you'll have

y = (slope) x + (intercept) .

So for choices 'A' and 'B', you have to massage the equation
into the standard form, and then just look at it and see whether
the slope is 9/4 and the intercept is -14.

A).         -9x + 4y =   -56

Add 9x to each side:    4y = 9x - 56

Divide each side by 4 :   y = 9/4 x - 14    <== Yes ! Good one.

B). 9x + 4y = 56

Subtract 9x from each side:   4y = -9x   + 56

Divide each side by 4 :       y = -9/4 + 14 <= no, signs are wrong

C). Yes. Slope is 9/4 and intercept is -14 .

D). No. Slope is 9/4 alright, but intercept is +14, not -14 .
