kumpel [21]

Answer:36

Step-by-step explanation:

$\frac{4}{7} =\frac{48\\}{84}$

for every 7 students there are 4 girls, so for every 84 there must be 48

7*12=84

4*12=48

so, in all 84 students there are 48 girls

so amount of boys=84-48=36

there are 36 boys

Which points are exactly 10 units from the point (–8, –2)? Check ALL that apply.

Archy [21]

Answer:

The points that are exactly 10 units from the point (–8, –2) are (2, –2) and (–8, 8).

Step-by-step explanation:

The distance formula is;

d= $\sqrt{( x_{2}-x_{1} )^{2}-(y_{2} -y_{1} )^{2} }$

So for distance between: (–8, –2) and (2, –2) is:

d= $\sqrt{( 2-(-8))^{2}-(-2 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Similarly for distance between: (–8, –2) and (–8, 8) is,

d= $\sqrt{( -8-(-8))^{2}-(8 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Alejandro made an error in the steps below when determining the equation of the line that is perpendicular to line 4x - 3y = 8 a

Ronch [10]

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(4/3) = -1......( perpendicular to a line with a slope of 4/3) because : 4x-3y =8...y=(4/3)x-8/3 ) </span>

<span>
a = -3/4 y=(-3/4)x+b
the line that passes through (3, -2) :- 2 = (-3/4)(3)+b
b =1/4
<span> the equation is : y = (-3/4)x+1/4</span></span>

Can you solve it no you cannot why? Because it doesnt have the amount of money he was allowed to spend thats what missing information is. Now extra information is when there is something in the problem <span>you DO NOT NEED to solve. Hope that helps you out.</span>

What is the volume of a cylinder with base radius 2 and height 6

jenyasd209 [6]

Answer:

Volume of the cylinder is 75.43

Step-by-step explanation:

Volume of Cylinder is $\pi r^{2} h$

where r is base radius = 2 and h is the height = 6

(22/7) × 2² × 6

= (22/7) × 4 × 6

= (22/7) × 24

= 528/7

= 75.43
