A telephone pole casts a 32-foot shadow, while a street sign next to the pole casts a 12-foot shadow. If the
telephone pole is 40 feet tall, what is the height of the street sign?
12

Answers

Answer 1

Answer: The height of street sign = 15

Step-by-step explanation:

At the same time, the angle made by the light on each object is the same.

Pole and street sign both standing vertical to the ground.

So triangle made by both of them are similar

The sides of similar triangles are proportional,

[tex]\dfrac{\text{height of street sign}}{\text{height of pole}}=\dfrac{\text{Length of the shadow made by street sign}}{\text{Length of the shadow made by pole}}\\\\\dfrac{\text{height of street sign}}{40}=\dfrac{12}{32}\\\\\text{height of street sign}=\dfrac{12}{32}\times40=15[/tex]

Hence, the height of street sign = 15

Answer:

11. x = 5

12. x = 24

Step-by-step explanation:

11.

8x° + 140° = 180°

(Linear pair angles)

8x° = 180° - 140°

8x° = 40°

x ° = 40°/8

x° = 5°

x = 5

12.

2x° + 42° = 90°

(complementary angles)

2x° = 90° - 42°

2x° = 48°

x ° = 48°/2

x° = 24°

x = 24

Answer:

x = 1.5

Step-by-step explanation:

Here, we want to get what x is

To arrive at the answer for x, we are going to use an important circle theorem equation

We have this as;

lh^2 = lj * lk

from the question;

lh = 1

lj = 0.5

lk = (0.5 + x)

Thus;

1^2 = 0.5(0.5 + x)

1 = 0.25 + 0.5x

0.5x= 1-0.25

0.5x= 0.75

x = 0.75/0.5

x = 1.5

If the interest 4,000 for 4 years is 1,280 what is the interest rate

Answers

Answer:

For example, with a $4,000 deposit and an annual interest rate of 8 percent, the simple interest after four years would be $1,280. This is calculated by multiplying the principal (P) by the rate (R) and by the rate of time (T): 4,000 x 0.08 x 4 = 1,280.

3(x+6)=24 I need help to find x​

Answers

Answer:

[tex]\boxed{\bold{x \ = \ 2}}[/tex]

Explanation:

3(x + 6) = 24

Simplify both sides of the equation

3(x + 6) = 24

(3)(x) + (3)(6) = 24 (Distribute)

3x + 18 = 24

Subtract 18 from both sides

3x + 18 − 18 = 24 − 18

3x = 6

Divide both sides by 3

3x / 3 = 6 / 3

[tex]\bold{x \ = \ 2}[/tex]

Answer:

x = 2

Step-by-step explanation:

Remeber this rule: PEMDAS

Even though parantheses comes first, we must take away 3 By dividing (since 3 is currently multiplying with x+6). Picture it like a ‘tail,’ and you must take the tail away first. so it would look like this:

3 ÷ 3 (x+6) = 24÷3

3 ÷ 3 cancels out, and 24 ÷ 3 equals 8, so now your equation becomes:

x + 6 = 8

now, we subtract 6 (since it is adding with x)

x + 6 - 6 = 8 - 6

positive 6 and negative 6 (aka 6-6) cancel out, and 8 - 6 = 2, so x = 2

Dora has three candles, which will burn for 3, 4 and 5 hours, respectively. If she wants to keep two candles burning at all times, what is the greatest number of hours she can burn the candles? (Dora has a clock that she can use to time the candles.)

Answers

Answer:

3 hrs 38.2 min, Candle 2 will be three times the length of candle 1

Step-by-step explanation:

If Dora burns candles that burn for 4 and 5 hours they burn for 9 hours combined one after another.

What are permutation and combination?

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

here,
Dora has three candles, which will burn for 3, 4, and 5 hours,
The combination of the hours of burning,
3 + 4 = 7 hours
4 + 5 = 9 hours
3 + 5 = 8 hours

Thus, if Dora burns candles that burn for 4 and 5 hours they burn for 9 hours combined one after another.

Urban rail systems have been proposed to alleviate traffic congestion, but results in many cities have been cited as evidence that this approach to traffic management is ineffective. For example, a U.S. city that opened three urban rail branches experienced a net decline of 3,100 urban rail commuters during a period when employment increased by 96,000. Officials who favor urban rail systems as a solution to traffic congestion have attempted to counter this argument by noting that commuting trips in that city represent just 20 percent of urban travel.
The response of the officials to the claim that urban rail systems are ineffective is most vulnerable to criticism on the grounds that it
A) presents no evidence to show that the statistics are incorrect
B) relies solely on general data about U.S. cities rather than data about the city in question
C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion
D) fails to show that the decline in the number of urban rail commuters in one U.S. city is typical of U.S. cities generally
E) provides no statistics on the use of urban rail systems by passengers other than commuters

Answers

Answer:

C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Step-by-step explanation:

The correct option is - C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Reason -

Option A is incorrect because the statistics can not be incorrect.

Option B is incorrect because they are not talking about the city.

Option C is correct because Urban rail reduces congestion.

Option D is incorrect because the opposers cited the example of one city and the supporters are presenting evidence in the case of that city itself.

Option E is incorrect because they are providing an explanation for why the commuters data given by opposers is not relevant. The opposers talked about commuters.
