Answer:

$21,013

Step-by-step explanation:

The equivalent value of {x} is equivalent to 2.046.

The cosine function (or cos function) in a triangle is the ratio of the adjacent side to that of the hypotenuse.

Given is the expression as -

cos(47) = x/3

We have the expression as -

cos(47) = x/3

{x} = 3 cos(47)

{x} = 3 x 0.682

{x} = 2.046

Therefore, the equivalent value of {x} is equivalent to 2.046.

 C

Step-by-step explanation:

i think

Answer:

C. 7t

Step-by-step explanation:

What we know:

We are looking for an expression equal to 4t + 3t.

There are 4 choices:

1. 7t²

2. 7 + 2t

3. 7t

4. 12t

The answer does end in t, but is only one term, so B is eliminated.

An exponent is not involved either, so A is also eliminated.

It shows an addition sign, not multiplication, so D is also out.

This leaves C, which is 7t.

Doing this mathematically, add like terms.

4t + 3t

7t

Answer:

9 times 800/9 equals 800. (Answer is 800/9)

Step-by-step explanation:

Key skills needed: Equation, Division, Fractions

1) Let's say the number is the variable "x".

2) So this means 9 times x = 800

9x = 800

3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9

Hope you understood and have a nice day!! :D

88.8888888889

The equation to any of these sorts of questions is the larger number (800) divided by the smaller number (9).

You can check your answer by multiplying the quotient by the smaller number (9). If you get the larger number (800), you were correct, anything else, the equation was done wrong.

Answer:

The equation of the line that passes through the point (1,3) and has a slope  of -32.

[tex]y=-32x+35[/tex]

Please check the attached graph too.

Step-by-step explanation:

Given

The point-slope form:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case:

m = -32

(x₁, y₁) = (1, 3)

substituting m = -32 and (x₁, y₁) = (1, 3) in the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-3=-32\left(x-1\right)[/tex]

Add 3 to both sides

[tex]y-3+3=-32\left(x-1\right)+3[/tex]

Simplify

[tex]y=-32x+35[/tex]

Therefore, the equation of the line that passes through the point (1,3) and has a slope  of -32.

[tex]y=-32x+35[/tex]

275/10 = 27.5

Answer: the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec

Step-by-step explanation:

Given the data in the question;

H/h = R/r

10/5 = 6/r

r 1 = 30/10 = 3

Also

10/h = 6/r

r2 = 6h/10 = 3/5 × h

Volume = 1/3πr²h

V = 1/3 × π × (3/5 × h)² × h

V =  1/3 × π × 9/25 × h³

V = 3π/25 × h³

Now

dv/dt = 3π/25 × 3 × h² × dh/dt

-5 = 3π/25 × 3 × 25 × dh/dt

-5 = 3π × 3 × dh/dt

-5 = 9π × dh/dt

dh/dt = -5/9π

dh/dt = -0.1768 cm/sec

therefore, the rate of the water level in the cone falling when it is 5cm from the bottom of the cone is -0.1768 cm/sec

Answer:

x=4 and y=2

Step-by-step explanation:

I'm not 100% sure but I substituted different numbers into the equation:

If x=4 and y=2 then 4+2=6 and 3x2=6 so it would be 6=6

Another option is x=7 and y=3 then 7+2=9 and 3x3=9 so it would be 9=9

I'm more confident with x=4 and y=2 because of the small size of the triangle.

I hope this helps! Good luck! :)

Answer:

OMG, Nickkkkk. It's Nyla from your 3rd block math classs. Lol, I literally looked up this question with no luck of an answer.

Step-by-step explanation:

The school club made $298.08 by selling the balloons.

Profit is calculated as total revenue less total expenses.

Given that, a school club sold 143 balloons for $3.50 each. They bought 150 balloons for $1.29 each, plus $8.92 for shipping.

Cost of balloons when they brought them = 1.29*150 = $193.5

Total cost = $193.5 + (shipping price) = $193.5 + $8.92

Total cost = $202.42

Cost at which they sold the balloons = 143*$3.50 = $500.5

Therefore, their total profit = $500.5 - $202.42 = $298.08

Hence, The school club made $298.08 by selling the balloons
