A famous monument is 300 ft tall. When it casts​ 210-ft shadow, a nearby tree casts a shadow that is 27 ft long. About how tall is the​ tree?

Answers

Answer:

38.57 feets

Step-by-step explanation:

Given that:

Height of monument, h = 300ft

Shadow of monument, s = 210 ft

Shadow of tree, s = 27ft

Height of tree, = x

Using the relation :

Height / shadow = height / shadow

Monument = tree

300 / 210 = h / 27

Cross multiply

300 * 27 = 210 * h

8100 = 210h

h = 8100 / 210

h = 38.57 feets

Everything at a store is on sale for 25% off. The regular price of a jacket is $35.00. What is the discount price?

Answers

= 35(0.75)

= 26.25

Lets get 5% by dividing 35 by 20

10. Harmony places the letters in the word DECEMBER into a bag. A letter will be randomly
selected and not replaced. Then another letter will be selected. What is the probability of
Hormony selecting a C and then an E?

Answers

Answer:

3/56

Step-by-step explanation:

There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to [tex]\frac{1}{8}[/tex] times [tex]\frac{3}{7}[/tex], which is equal to [tex]\frac{3}{56}[/tex].

Answer:

$6.50 per bag of popcorn

Step-by-step explanation:

let a bag of popcorn be represented by p and a candy bar be b

28p + 40b= $282

17p + 20b= $160.50

this is an example of stimatanelous equations

so you have to double the second equation to give 34p + 40b =$321

subtract the equations to give one

6p =$39

divide $39 by 6 to give the value of one bag of popcorn = $6.50

Answers

Answer:

B. y = 3x + 1

Step-by-step explanation:

We can look at the table like a bunch of values, where (x) is what is inserted into the equation, and (y) is what comes out.

Now, simply insert the (x) values into each equation and see if they work out or not.

y = (1/3)(-1) + 1 does not equal -2, meaning this equation is defunct.

y = 3(-1) + 1 = -2; y = 3(0) + 1 = 1. This must be the equation as it works for the (x) values given. You can try the other equations, but a simple look at them is all you need to prove them false.

On a map of hiking trails, 0.5 inch represents 1 mile. A trail is shown as 1.25 inches long on the map. How long is the actual trạil?

Answers

Answer:

2.5 miles

Step-by-step explanation:

Answer:

The actual trail length is 2.5 miles.

Step-by-step explanation:

Let's solve this. 0.5 inches on the scale = 1 mile. Since the trailer is 1.25 inches long on the scale, let's first multiply 0.5 by 2. You would get 1 inch on the scale, which would be 2 miles.

2 miles = 1 inch on the scale. But it says 1.25, so since 0.5 inches is 1 mile, then 0.25 inches is 0.5 miles. Add 2 miles and 0.25 miles, and you will get 2.5 miles.

The trailer length is 2.5 miles.

find the 29th term of the arithmetic sequence 182,176,170

Answers

9514 1404 393

Answer:

  14

Step-by-step explanation:

The first term of the sequence is 182, and the common difference is 176-182=-6. So, the general term is ...

  an = a1 +d(n -1)

  an = 182 -6(n -1)

The 29th term will be ...

  a29 = 182 -6(29 -1)

  a29 = 14
