A store sells peanuts by the pound. Jerry paid 4.59 for 5.4 pounds of peanuts. At that rate, how much would he pay for 7.8 pound

nikdorinn [45]

If $4.59 = 5.4 peanuts
$x = 7. 8 peanuts

Cross multiply and you get:

5.4x = (4.59)(7.8)
x = ((4.59)(7.8)) / 5.4
x = $6.63

Find x and y please

Alexandra [31]

Answer:

Answer:

x → 4.24
y → 4.24

Step-by-step explanation:

» x and y can only be got through using trigonometric ratios:

✍ For x :

${ \tt{ \sin( \theta) = \frac{opposite}{hypotenuse} }} \\ \\ { \tt{ \sin(45 \degree) = \frac{x}{6} }} \\ \\ { \tt{x = 6 \times \sin(45 \degree) }} \\ { \tt{x = 4.24}}$

✍ For y :

${ \tt{ \cos( \theta) = \frac{adjacent}{hypotenuse} }} \\ \\ { \tt{ \cos( 45 \degree) = \frac{y}{6} }} \\ \\ { \tt{y = 6 \times \cos(45 \degree) }} \\ { \tt{y = 4.24}}$
