Referring to the Fig. in Question #40, find the unknown
length Y.
Answer:
tan30°=7/x
[tex] \frac{1}{ \sqrt{3} } = \frac{7}{x } \\ x = 7 \sqrt{3} [/tex]
cos30°=x/y
[tex] \frac{ \sqrt{3} }{2} = \frac{7 \sqrt{3} }{y} \\ \\ 7 \sqrt{3} \times 2 = \sqrt{3} \times y \\ \frac{7 \sqrt{3 } \times 2}{ \sqrt{3} } = y \\7 \times 2 = y \\ 14 = y[/tex]
tell me if it's wrong.

-24x = -3 what is the solution to the equation?
Answer:x = 1/8 = 0.125
Step-by-step explanation:Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-24*x-(-3)=0
Pull out like factors :
-24x + 3 = -3 • (8x - 1)
Solve : -3 = 0
Solve : 8x-1 = 0
Add 1 to both sides of the equation :
8x = 1
Divide both sides of the equation by 8:
x = 1/8 = 0.125
Answer:
1/8 = 0.125

Sarah babysits her neighbor's son to make money. Her earnings can be represented by the equation
M = 9h
where M is the money she earns and h is the hours she babysits.
Samara babysits her cousin to make money. Her earnings can be represented by the graph.
Answer:
27
Step-by-step explanation:
Due to the fact that M=9h you must do M=9(3).
M stands for the amount of money that Sarah will receive for babysitting. H stands for the amount of hours Sarah is babysitting. $9 is the amount of money Sarah makes per hour.
You get the number 3 by seeing where the blue dot is and scrolling down.
Therefore, M=9(3)
The answer is 27
What cross-section do you get when you give a horizontal cut to a die? The Chapter is Visualising solid shapes.
Answer:
Horizontal cut: We will get 2 semi-circle shape pieces of the same diameter. Vertical cut: We will get 2 rectangular shape pieces of length half the side of the dice but breath will be the same as the side of the dice.
Answer:
With a horizontal cut, you will get 2 semi-circle shape pieces of the same diameter.
Now, with a vertical cut you'll get 2 rectangular shape pieces of length half the side of the dice but breath will be the same as the side of the dice.

A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below.
2 times 8 + (negative 320) = 336
Which explains whether Brenda is correct?
1. Brenda is correct because her answer represents 336 feet below sea level.
2. Brenda is correct because Negative 16 + (negative 320) = 336.
3. Brenda is not correct because the new position is 2 times 8 + (negative 320) = negative 304.
4. Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336.

Find the rule, and type the missing number in the sequence
96, 192, _, 384
Answer:
96, 192, 288, 384
Step-by-step:
First we find the difference between the first 2 digits so we subtract them both from each other
192-96
which is
=96
therefore its safe to say that +96 is the rule of the sequence
so I did 192+96 to find the missing number which gave me
=288
