144 coins are divided equally among some children. If there were 3 children fewer, each child would have 16 coins. How many children are there?

Answer:

[tex]2\sqrt{13}[/tex]

Step-by-step explanation:

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c^{2} = 4^{2} + 6^{2}[/tex]

[tex]c^{2} = 16 + 36[/tex]

[tex]c^{2} = 52[/tex]

[tex]\sqrt{c^{2} } = \sqrt{52}[/tex]

[tex]\sqrt{52} = 2\sqrt{13}[/tex]

Answer:$51.20 commission

Step-by-step explanation:

Answer:

Step-by-step explanation:

Assuming that the Skateboard is $180, and you are asking for the price when it is 30% off.

180 * .70 = $126

Another way of solving the question is finding 10 % of 180, which is 18. And you are looking for 30% less, so 18 * 3 = 54, which is 30% of 180.

180 - 54 = 126

Answer:

26.83

Step-by-step explanation:

H=1.2L + 27.8

60=1.2x+27.8

minus 27.8 from both sides

32.2=1.2x

divide both sides by 1.2

x=26.83

Answer:

class B

Step-by-step explanation:

Answer:

There is no solution (since none has side length of 4 units)

Step-by-step explanation:

If V (-1,1) is one of vertex of a square, then the next vertex to V distance must be the known value of 4

VA: V to (-3,3)   = √(-1 - -3)² + (1 - 3)² = √8 = 2.8

VB: to (-5,-3)     = √(-1 - -5)² + (1 - -3)² = √32 = 5.7

VC: o (3,3)        = √(-1 -3)² + (1 - 3)² = √20 = 4.47

VD: to (-5,3)      = √(-1 - -5)² + (1 - 3)² = √20 = 4.47

VE: to (4,5)        = √(-1 - 4)² + (1 - 5)² = √41 = 6.4

Answer:

B

Step-by-step explanation:

n - 4 = 4.5 - 4 = 0.5

8(n - 4) = 8 *(0.5 ) = 4

6 *n = 6 * 4.5 = 27

8(n - 4) + 6n

8(0.5) + 6*4.5

4 + 27

31

Answer:

B.) 31

Step-by-step explanation:

Since the is [tex]8(n-4),[/tex] we substitute it with [tex]8x4.5-8x4.[/tex] [tex]8x4.5=36,[/tex] [tex]8x4=32.[/tex]

Now, it is [tex]36-32+6n[/tex].

[tex]6x4.5=27[/tex].

[tex]Now, 36-32+27.[/tex]

Answer:

C

Step-by-step explanation:

Answer:

A. 40°

Step-by-step explanation:

As we can see it is an isosceles triangle because two sides are equal. so Base angles of an isosceles triangle are equal. Then Now.,

70° + 70° + <X = 180° {Being sum of angles of triangle }

140° + < X = 180°

< X = 180° - 140°

< X = 40°

Answer:

#11 21

Step-by-step explanation:

You have the right steps for question 10, let me work #11 n/3 -5 = 2

So following your steps: move the -5 so n/3 = 2+5 so n/3 = 7, now

multiply both sides by 3 so n = 21

Answer:

F=140°

Step-by-step explanation:

130+120+110=360

720-360=360

40+60+20=120  360+120=480

480÷3=160  x=160

160-20=140

Answer:

Complementary angles, adjacent angles

Step-by-step explanation:

Which relationships describe angles 1 and 2?

Options: Complementary angles, vertical angles, supplementary angles, adjacent angles

Angles 1 and 2 are opposite to the 90° angle. So, the angles' relationship to that angles is a vertical angle, meaning that the two add up to 90°.

Complementary angles add up to 90°, so this option is correct.

Vertical angles are the pairs of opposite angles formed by two intersecting lines. Because the two angles do not follow this definition, this option is incorrect.

Supplementary angles add up to 180°. However, we know that the two add up to 90°, so this option is incorrect.

Adjacent angles are angles that are next to each other, so this option is correct.

I hope this helps! Feel free to ask any questions!

i used C to answer. you go backwards 8(-8), and then I go down 7(-7)

Answer:

10

Step-by-step explanation:

we can solve this using basic algebra

We set up the equation using the info that each video costs $5 and that we but 12 of them

12(1 * 5) + x = 70

(Please note: 1x = x)

12(5) + x = 70

60 + x = 70

60 - 60 + x = 70 - 60

x = 10
