sin(angle) = opposite/hypotenuse

sin(A) = BC/AC

sin(A) = 24/30

sin(A) = (6*4)/(6*5)

sin(A) = 4/5

Answer:

2 ÷ 3

Step-by-step explanation:

Let us suppose the money be 90

Since caroline gets 1 by 9 of the money i.e. 10

And, the remaining money would be distributed among Colin and sarah in the ratio of 1:3

So, the remaining money would be

= 90 - 10

= 80

So, the sarah could get

= 80 × 3 ÷ 4 ÷ 90

= 60 ÷ 90

= 20 ÷ 30

= 2 ÷ 3

Answer:

  6 18/25 = 6.72

Step-by-step explanation:

The right triangles are similar, so corresponding sides are proportional.

  ∆XZY ~ ∆ZWY

  XZ/XY = ZW/ZY

  24/25 = x/7

  x = 7(24/25) = 168/25

  x = 6 18/25 = 6.72

Answer:36

Step-by-step explanation:

[tex]\frac{4}{7} =\frac{48\\}{84}[/tex]

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

Answer:

x>30

Step-by-step explanation:

x/-3<-10

x<-10*-3

x<30

x>30

Answer:

x > 30

Step-by-step explanation:

Multiply both sides by -3:  This results in x > 30.  Note that the direction of the inequality sign has been reversed, as is required when we multiply or divide an inequality by a negative number.

Answer:

He is not correct.

Step-by-step explanation:

This is because when you subtract -11 and 10.75, you get the answer of -21.75 instead of -0.25. He added the expression instead of subtracting it. Hope it helps

============================================================

Explanation:

Place point F on line AB such that it is to the left of point A. In other words, point A is between points F and B.

Angle CAB is 105 degrees, so this makes angle CAF to be 75 degrees. This is because 105+75 = 180. The two angles are a linear pair.

Angle CAF is the angle formed between the tangent line AB and the chord segment AC.

Due to the tangent-chord theorem, inscribed angle CEA is also 75 degrees. Note how this inscribed angle subtends the arc cut off by the chord.

The inscribed angle theorem says we can double that inscribed angle to get 2*75 = 150, which is the measure of minor arc AC.

Arc CEA is therefore 360-(minor arc AC) = 360-150 = 210 degrees

Step-by-step explanation:

First you divide 529 and 23. You can divide 5w9 by 23 in a fraction like this 529/23 on to Desmos scientific calculator or just 529÷23 on a calculator. If it is a decimal, round it up if the tenth, hundredth, or thousandth is 5, 6, 7, 8, 9 or round down if the number is 4, 3, 2, and 1. The answer to 529÷23 is 23. And if you estimate it, it'll be 20. The next part may be a bit confusing but if you estimate 23, you'll get 25.

Then you estimate 529 and 23, you'll get 530 and 20. And if you divide them, you'll get 26.5. And if you estimate that, you'll get 27. So that means is 2 or 7 off from the estimated from the equation 529÷23. So that means the reasonable answer is probably 25 or 27.

Tell me if I'm right or not, and I'm sorry if I'm wrong because I don't know what answer I explained in the two paragraphs I wrote is right or wrong.

Slant height of a cone:

s = √(r2 + h2)

Answer:

7)

to work it out:

180-110= 70

because there are two unknown angle we're gonna assume they're both the same amount. So if they are both the same and equal then we need to half 70 which will be equal to the two sided. So. 70/2= 35

So the 2 x's = 35 each

8)

you need to put this all into an equation so:

7x-11 + 5x-2 + 2x-3 = 180 degrees

12x - 9 + 2x-3

10x + 6

Actual answer:

14x-16

The second option (5d = 55)

This works because Arianna wants to divide the amount of dominos to her 5 friends. We do this by dividing 55 by 5.

d will then equal 11 (d = 11).

Answer:

[tex]x=2.\ y=1[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ the\ following\ pair\ of\ equations:\\5x+7y=17\\7x+5y=19\\Now,\\As\ the\ co-efficients\ of\ none\ of\ the\ algebraic\ terms\ match,\\We\ can\ take\ the\ LCM\ of\ their\ co-efficients;\\As\ the\ co-efficients\ of\ the\ x-terms\ are\ 5,7\ respectively;\\Their\ LCM\ is\ 35.[/tex]

[tex]Hence,\\7(5x+7y)=7(17)\\-5(7x+5y)=-5(19)\\Hence,\\35x+49y=119\\-35x-25y=-95\\Hence,\\Adding\ the\ two\ equations\ we\ have:\\(35x+49y)+(-35x-25y)=(119)+(-95)\\(35x-35x)+(49y-25y)=119-95\\24y=24\\y=\frac{24}{24}=1[/tex]

[tex]Now,\\Lets\ consider\ the\ First\ Equation:\\5x+7y=17\\Substituting\ y=1,\\5x+7*1=17\\5x+7=17\\5x=17-7\\5x=10\\x=\frac{10}{5}=2\\\\Together,\\x=2.\ y=1[/tex]
