A buyer purchases 75 yards of material for $120. Then an additional 90 yards are ordered. What is the additional cost?

Answer:

$128

Step-by-step explanation:

1. We need to find how much 1 yard of material cost.

If needed, use a calculator*

120/75=1.6

2. Now we need to know how much 15 yards of material cost.

1.6 times 15=24

3. The buyer ordered an additional 90 yards. If we know how much 75 yards cost, and 15 yards, all you have to do is...

120+24=144

90 yards=$144

4. The additional cost is $144

(Note: the total cost would be $264 (120+144=264))

Liula [17]

Answer:

24.59 feet

Step-by-step explanation:

Let x represent the distance between Sam and the bird.

We have been given that am the owl is looking down at a 24° angle from the top of a tree that is 10 ft tall, when he spots a bird on the ground. We are asked to find the distance between Sam and the bird.

We can see from our attachment that Sam, the bird and angle of depression forms a right triangle with respect to ground. We can see that side 10 ft is opposite side and and side x is hypotenuse for the 24 degree angle.

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

\text{sin}(24^{\circ})=\frac{10}{x}

x=\frac{10}{\text{sin}(24^{\circ})}

x=\frac{10}{0.406736643076}

x=24.5859333557

x\approx 24.59

Therefore, the bird is approximately 24.59 feet away from Sam.

Given<br> mZLON is a straight angle. <br> Definitely I need help I’ll give brainless ^^
anastassius [24]

Answer:

m∠LOM=48°

Step-by-step explanation:

∠LON=180° AND ∠LON=∠LOM+∠MON

⇒ 7x-92+6x+12=180

⇒13x=180+92-12

⇒x=20

m∠LOM=7x-92°=140°-92°=48°

Birth and death rates of animal populations typically are not constant; instead, they vary periodically with the passage of seas
Dominik [7]

Answer:

We readily separate the variables and integrate:  

∫dP/P=∫(k+bcos2\pit)dt

ln P=kt+(b/2\pi)*sin2\pit+ln C

Clearly C = Po, so we find that P(t) = Poexp(kt + (b/2\pi)* sin 2\pit). The 271- curve with the typical numerical values P_o = 100, k = 0.03, and b = 0.06. It oscillates about the curve which represents natural growth with P_o and k = 0.03. We see that the two agree at the end of each full year.
