Which equation can be solved to find one of the missing side lengths in the triangle?aB60512 unitsАCOS(60°) =22 믕cos(60°) = 12Su

Mekhanik [1.2K]

In a right rectangle, we have:

$\sin \alpha=\frac{opposite}{hypotenuse}$ $\cos \alpha=\frac{\text{adjacent}}{hypotenuse}$

For your exercice, hypotenuse=12

The exercise also inform the angle 60°, then:

$\sin \text{ 60}=\frac{\text{opposite}}{\text{hypotenuse}}=\frac{b}{12}$ $\cos 60=\frac{adjacent}{\text{hypotenuse}}=\frac{a}{12}$

Create an equivalent system of equations using the sum of the system and the first equation. x + 4y = 8 4x + y = 2

qaws [65]

Answer:

Equivalent systems of equations review

Step-by-step explanation:

We're given two systems of equations and asked if they're equivalent.

x + 4y = 8 (1)

4x + y = 2 (2)

Interestingly, if we sum the equations in System A, we get:

$x + 4y = 8 \\4x + y = 2 \\$

$5x+5y=10$

Replacing the first equation in System A with this new equation, we get a system that's equivalent to System A:

$5x+5y=10$

$4x + y = 2$

This is System B, which means that System A is equivalent to System B.

-3(x+2)=12. solve for x

bagirrra123 [75]

Steps to solve:

-3(x + 2) = 12

~Distributive Property

(-3 * x) + (-3 * 2) = 12

~Simplify

-3x - 6 = 12

~Add 6 to both sides

-3x - 6 + 6 = 12 + 6

~Simplify

-3x = 18

~Divide -3 to both sides

-3x/-3 = 18/-3

~Simplify

x = -6

Best of Luck!

2. If x is directly proportional to y^3 and x=32 when y=2, i) Find an equation

svp [43]

Answer:

(i)

$x \alpha y {3} \\ \frac{x}{y {3} } = k$

(ii)

$\frac{x}{y {3}^{} } = \frac{x}{y {3}^{} } \\ \frac{32}{ {2}^{3} } = \frac{x}{6 {}^{3} } \\ \frac{32}{8} = \frac{x}{216} \\ x = 864$

(iii)

$\frac{32}{8} = \frac{108}{y {}^{3} } \\ {y}^{3 } = 27 \\ y = \sqrt[3]{27 } \\ y = 3$

Please help, if u get it right i will give u brainliest

padilas [110]

Answer:

2.27%

Step-by-step explanation:

Lets start by making the names letters, J C and A respectively.

The total is 44 dollars. J paid 34%, which would be 14.96. He pays a total of $15. C paid 50%, which is 22 dollars. A pays 17%, which would be 7.48. She pays a total of $8.

15 + 8 + 22 = $45, meaning they paid an extra 1 dollar. One dollar is 1/44th of $44, or 2.27%.

Note: 2.27% is 2.272727272727 repeated, do what you will with that information, every site is different.
