Answer:

14.1 =x

Step-by-step explanation:

Since this is right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 42 = x /21

21 sin 42 = x

14.05174273 =x

Rounding to the nearest tenth

14.1 =x

Answer:

x = 14.1 (Rounded to the nearest tenths)

Step-by-step explanation:

Since the opposite side of the angle given needs to be found out and hypotenuse, Sin ratio would be used;

Sin(42) = [tex]\frac{x}{21}[/tex]

=> Now multiply 21 on both sides of =, in order to isolate x;

Sin(42) * 21 = x

14.1 = x

Answer:

i its 3 or 4

Step-by-step explanation:

Answer:

Stefan originally spent $ 110 on the bike and helmet, with which he is making a profit of $ 33.

Step-by-step explanation:

Since Stefan sells Jin a bicycle for $ 125 and a helmet for $ 18, and the total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet, to determine how much did Stefan spend originally and how much money did he make by selling the bicycle and helmet to Jin, the following calculations must be performed:

130 = 125 + 18

100 = X

100 x (125 + 18) / 130 = X

100 x 143/130 = X

14,300 / 130 = X

110 = X

143 - 110 = 33

Therefore, Stefan originally spent $ 110 on the bike and helmet, with which he is making a profit of $ 33.

Answer:

Length of BC = 12 inch

Step-by-step explanation:

Given:

ΔABC is a right angle triangle

Length of AB = 9 inch

Length of AC = 15 inch

Find;

Length of BC

Computation:

Using Pythagoreans theorem;

Hypotenues² = parpendicular² + Base²

Step 1 :

AC² = AB² + BC²

Step 2 :

15² = 9² + BC²

Step 3 :

225 = 81 + BC²

Step 4 :

225 - 81 = BC²

Step 5 :

BC² = 144

Step 6 :

BC = √144

Step 7 :

BC = 12 inch

Length of BC = 12 inch

Answer:

3 goals

Step-by-step explanation:

Lets say the 12 goals is 100%

Luke scored 25% of those goals

So to find 25 percent of 12 multiply 12 by the percent 25

25 times 12 is 300

divided by 100 is 3

Luke scored 3 goals

Tell me if this is wrong if not

Answer:

x = 35 and y = 100

Step-by-step explanation:

Let x = dollar cost per dive  and y = dollar cost per night.

ATQ,

4x+3y = 440 .....(1)

and

8x + 5y = 780 .....(2)

Multiply equation (1) by 2.

8x+6y = 880......(3)

Subtract equation (3) from (2).

8x + 5y -(8x+6y)= 780-880

-y = -100

y = 100

Put the value of y in equation (1).

4x+3(100) = 440

4x = 440-300

4x = 140

x = 35

Hence, the value of x is 35 and that of y is 100.

Answer:

17 servings

Step-by-step explanation:

This is a fairly easy question. Here is what you need to do to solve.

The whole chocolate bag is 25.5 oz, and each serving is 1.5 oz.

So divide 25.5 by 1.5 to get your answer of 17 servings per bag!

Answer:

Least speed = 33.66 km/h

Step-by-step explanation:

The least distance is 119.5 km, and the most time it took was 3.55 hours.

Therefore the least speed = least distance/most time

= 119.5/3.55 km/h

= 33.66 km/h

Answer:1.107 is how much tax she will pay

Answer:

The table in the exercise can be completed with the next results:

Step-by-step explanation:

As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:

Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:

When x is 2:

When x is 4:

When x is 6:

When x is 8:

At last, to obtain the graph you can use the formula made: y = x + 7, and you'll obtain a graph like the attached picture, where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7.

Answer:

Step-by-step explanation:

strategy:  find the distance of the two points,   take half of that,  b/c that will be the radius,   Then use   the area of a circle formula to find the answer

P1 = (1,-1)   in the form (x1,y1)

P2= ((3,3)  in the form (x2,y2)

dist = sqrt [ (x2-x1)^2 + (y2-y1)^2 ]

dist = sqrt [ 3 -1 )^2 + 3-(-1)^2 ]

dist = sqrt [ 2^2 + 4^2 ]

dist = sqrt [ 4 + 16 ]

dist = sqrt [20]

r = [tex]\sqrt{20}[/tex] /2

area of circle = [tex]\pi[/tex][tex]r^{2}[/tex]

area of circle = [tex]\pi[/tex]([tex]\sqrt{20}[/tex] /2)^2

area of circle = [tex]\pi[/tex]([tex]\sqrt{20}[/tex] /2)([tex]\sqrt{20}[/tex] /2)

area of circle = [tex]\pi[/tex](20 / 4)

area of circle = [tex]\pi[/tex]5

area of circle = 5[tex]\pi[/tex]

Answer:

c

Step-by-step explanation:

c because you would get fals as the answer because to solve you first distribute so you would get 3x+7=3x+6 and both 3 x's would cancel out so you would get 7=6 so that would be false

Answer:

y=4x+2 or f(x)=4x+2

Step-by-step explanation:

This is because the equation format for a line is y=mx+b, the slope is m and the y-intercept is b. So all you have to do is fill it out to get y=4x+2. Or the other way I listed the equation is right too. Hope this helps!
