You buy 10 pounds of birdseed at Store A for $11.50. Your friend buys 15 pounds of birdseed at Store B for $19.50. How much less would you spend buying 20 pounds of birdseed at the store with the better deal and why?

Answers

Answer:

The answer is three

Step-by-step explanation:

$11.50/10 = $1.15 per pound

$19.50/15 = $1.30 per pound

$1.15 * 20= $23

$1.30 * 20 =$26

$26- $23 = $3

answer: $3

Answer: You would spend $3 less at store A with 23 and Store B with 26

Step-by-step explanation: Store B: 15 pounds / 19.50 = $1.3*20 =$26

Store A: 10pounds =11.50*2=$23

Valerie shares some of the 12 candies from this box.she gives her friend 1 candy for every 3 candies she eats herself. How many candies does she give to her friend?

Answers

Answer:

3

Step-by-step explanation:

Every group of candies eaten is 4 candies because Valerie eats 3 and her friend eats 1. 1+3 = 4 . 12/4 = 3

Step-by-step explanation:

1 : 3 = 4 <-- simplified ratio

x : y = 12 <-- trying to find the real ratio

12 ÷ 4 = 3 <-- find the unit rate

1 × 3 = 3 <-- find how much the friend has

So, her friend got 3 candies

Step-by-step explanation:

multiply both sides by 4 to cancel the fraction 1/4x so you can add them together

so once you multiply both sides by 4 the equation is

2x+20=x+32 so then combine like terms but subtracting x so that's

can someone help me with this question lol, i’ll mark as brainliest if correct

Answers

Hi there! Before we start with your problem. Recall the Trigonometric Function of (-x) first.

sin(-x) = -sinx cos(-x) = cosxtan(-x) = -tanx

Now what we need to do is to imagine a unit circle. We know that angle (-x) rotate clockwise while (x) rotates counterclockwise.

Now imagine if it rotates clockwise, it:d start at the fourth quadrant first. That means the y-value is negative while x-value is positive.

We also know that (x, y) = (cos, sin)

Now move to the 2(pi)/3.

[tex] \large{ \frac{2 \pi}{ 3} = \frac{2(180)}{3} \longrightarrow 2(60)= \boxed{120 \degree}}[/tex]

Thus, the value of 2pi/3 is 120°

Now imagine again. In a unit circle, 120° is in second quadrant if we rotate counterclockwise. But if we rotate clockwise, where would the 120° be? Remember that (-x) rotates clockwise. That's right! (-120°) is in the third quadrant. In the third quadrant, cos is negative there along with sin.

So we can conclude that:

cos(-120°) is in third quadrant. cos and sin are negative in third quadrant.

120° is also a reference angle of 60° because of 180°-60° = 120°

Thus,

[tex] \large{cos( - \frac{2 \pi}{3} )= cos( - 120 \degree) = cos(120 \degree) \longrightarrow - \frac{1}{2} }[/tex]

Answer/Conclusions

cos(-2pi/3) = -1/2cos(-2pi/3) use the reference of 60°cos(-2pi/3) is in third quadrant.
