WILL GIVE BRAINEST!!! PLEASE HELP

Mathematics
1 answer:
erik [133]3 years ago
3 0

Answer:

1.) The point (24,30) would not be on the line

2.) The point (12,13) would not be on the line either

4.) The slope is a fraction of 2/1

Bonus: y = (2/1)x - 2

Step-by-step explanation:

For question three, I looked at the (6,10) point on the graph and compared it with the (a,8) point. That showed me that the y coordinate always moves by 2. Then I looked at the (6,10) coordinate and the (a,8) coordinate and the (4,b) coordinate and saw that there was one x coordinate between 6 and 4 so it must be five. That means the x coordinate moves by 1.

Let me know if you need more help!

Sara sells dishwashers. She earns an 8% commission on sales. How much must he sell in order to earn $3000?
andrezito [222]
Well, if we look at a calculator and ask, what is 8% of 3000$ we get the answer of 240 dollars.

3000 - 8% = 2760 therefor we know it removes 240 dollars. So the commission is 240 dollars.

Can you help me? sin 35 (degrees) Thanks!
Nata [24]
<span>OK, here's a *very* approximate "creative" method: 
</span><span>
sin(a+b)=sin(a)cos(b) + cos(a)sin(b) </span>
<span>
choose a=30deg and b=5deg </span>
- sin(a)=0.5 (exact) 
- b is a small number so we say sin(b)~b (in radians). We can do a long division for this: 3.14/36 = 0.087 radians 
- similarly, for b sufficiently small, cos(b)~1 
<span>- now we only need cos(a) = sqrt(3)/2. We can approximately calculate sqrt(3) as 1.73, (by trial-and-error or better, by using the Babylonian method;  so sqrt(3)/2 = 0.865 </span>
<span>
Finally, sin(30 + 5) = (0.5 x 1) + (0.087 x 0.865) = 0.575 (calculating more digits is of no use because the sin(b)=b and cos(b)=1 are quite inaccurate approximations). </span>

<span>So that wasn't all too much effort, and we're close to the correct answer (0.574)


I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

The total mass of Abdul and his baby brother is 15.25kg . The mass of Abdul and his father is 72.25kg . The mass of Abdul's fath
Helen [10]
A+b=15.25

a+f=72.25, since f=13b

a+13b=72.25  so now we have two equation in two variables...

a+13b=72.25 and a+b=15.25  so we can say:

(a+13b=72.25)-13(a+b=15.25)

a+13b-13a-13b=72.25-198.25

-12a=-126

a=10.5 kg

So Abdul's mass is 10.5 kilograms.

Simplify the square root of 4/ 3 to the square root of 4
WARRIOR [948]

Answer:

D

Step-by-step explanation:

Whenever 'to' is used we multiply the given values

(\sqrt{4/3}) *(\sqrt{4} )\\(\sqrt{2^{2} } /\sqrt{3} )*(\sqrt{2^{2} } )\\(2/\sqrt{3} )*(2)\\(2*2)/(\sqrt{3} )\\(4)/(\sqrt{3} )\\4*(\sqrt{1/3})
