Solve for x. Round to the nearest tenth of a degree, if necessary PLEASE HELP I HAVE 10 MINS TILL ITS DUE
grigory [225]

Answer:

x = 47.4

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta  = adj / hyp

cos x = 8.8 / 13

Take the inverse cos of each side

cos ^-1 ( cos x) = cos ^-1( 8.8 /13)

x = cos ^-1( 8.8 /13)

x =47.39633319

Rounding to the nearest tenth

x =47.4

Travka [436]

Answer:

Step-by-step explanation:

R=x/7 let's say R is what Ryan earned, and so he earns x dollars every seven days

L=2(R)

L=2(x/7)Let's say L is what Lee earned, she earned twice as much as Ryan so 2(x/7)

Total=2(x/7)+x/7

Total=3(x/7)   the total earnings is the sum of x/7 and 2x/7 is 3x/7

The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?
vlabodo [156]

Answer:

<h2>Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4</h2>

Step-by-step explanation:

The volume of a cube is expressed as L³ where L is the length of each side of the cube.

Given volume of a cube = 64in³

On substituting;

64 = L³

Taking the cube root of both sides to determine L we have;

\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4

Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4
