A construction crew is building a two story house, but they have not built the staircase between the floor yet. The height of the staircase is 12 feet, the base of the stairs will be 6 feet from the wall. How long does the temporary ramp need to be to the nearest tenth of a foot?

Answers

Answer 1

Answer:

13.4feet

Step-by-step explanation:

The set up forms a right triangle.

Given

Height of the staircase h = 12 feet

Base of the stairs b = 6feet

Required

Length of the ramp l

Using the pythagoras theorem

l² = h² + b²

l² = 12²+6²

l² = 144 + 36

l² = 180

l = √180

l = 13.42 feet

Hence the length of the ramp to the nearest tenth is 13.4feet

PLEASE HELP WILL GIVE BRAINLIEST ANSWER!!! Thanks

Answers

Answer:

please check explanations

Step-by-step explanation:

As we all know, i is same as root of -1

let us expand what we have;

(1 + i)^2

= 1(1 + i) + i(1 + i)

= 1 + i + i + i^2

as i is square root of -1, the square of the square root of -1 is -1

Thus, we have

1 + 2i - 1

= 2i

The equation h=60-4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain

Answers

Answer:

40m

Step-by-step explanation:

Complete question

The equations h = 60 - 4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain. How high is the water after 5 minutes.

To get the height of the water after 5minutes, we will find h at when m = 5

h = 60 -4 (5)

h = 60 - 20

h = 40m

Hence the water is 40m high after 5minutes

Answers

Answer:

y = 6x + 104

Step-by-step explanation:

Given the equation in the form:

y = mx + b

m = slope ; b = intercept

Given the data:

5 days - $134 10 days - $164 15 days - $194 20 days - $224

To obtain the slope, Pick the points :

(5, 134) and (20, 224)

Slope = y2 - y1 / x2 - x1

Slope, m = (224 - 134) / (20 - 5) = 90 / 15 = 6

Plugging into the equation :

We have ;

y = 6x + b

Picking any point from the data and plugging in to solve for b:

(10, 164)

164 = 6(10) + b

164 = 60 + b

b = 164 - 60

b = 104

Equation finally becomes ;

y = 6x + 104

Factor X^2-13x+22 help pls

Answers

Answer:

(x-2)(x-11)

Step-by-step explanation:

Answer:

(x - 2)(x - 11)

Step-by-step explanation:

We have a polynomial and are asked to factor it.

Polynomial : x^2 - 13x + 22

Usually a trick I follow when factoring is that for c (in this case 22). You need to find two numbers that will multiply to it. And for b (in this case -13) you will need to find two numbers that will add to it, the same numbers you multipled for c.

So

x * y = 22

x + y = -13

These two numbers are -11 and -2.

Step-by-step explanation:

hey hey. i’ll help you. sorry if this is long. :)

okay so let’s think about this. there’s a lot of extra information that we don’t need so let’s get rid of everything up to ”7 years”.

now.. she works 40 hours per week right? and she makes $2.13 per hour. so now that we have that, let’s think what 40 x $2.13 is. if you do the math right you should get 85.2 or $85.20. so that’s in one week, but then in a typical week sheserves 75 tables that have an average bill of $4q. so now that we have those numbers, we take 41 x 75 then add it to our weekly number. so we multiply the two together and we get 3075. not 30.75 but $3075.00! so take that and add it to 85.20.. you should get 3160.2, or $3160.20. but then typically an 18% tip, so let’s go back to the number before (41) and find what 18% of 41 is.

18% of 41 is 7.38 or in this case, $7.38. so once we have that, you’re gonna want to multiply 7.38 by 75 to get that total. if you do that you should get 553.5

okay.. now we have all the numbers we need. we’re already basically done, we just need to add the tips to the other total!

$3160.20 + $553.50 = $3713.70

so in a week, she makes $3713.70

i hope this helped you! good luck!

In a bag of marbles, 1/2 are red, 1/4 are blue, 1/6 are green and 1/12 are yellow. You pick a marble without looking. What color marble are MOST likely to be choose?

Answers

Answer:

Its red becasue 1/2 is greater than all of them

The most likely color of the marble that will be chosen is red.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

Number of red marbles in the bag=1/2

Number of blue marbles in the bag=1/4

Number of green marbles in the bag=1/6

Number of yellow marbles in the bag=1/12

Now,

To determine the most likely color of the marble that will be chosen, we need to calculate the probability of selecting each color. The probability of selecting a red marble is 1/2, the probability of selecting a blue marble is 1/4, the probability of selecting a green marble is 1/6, and the probability of selecting a yellow marble is 1/12.

To compare the probabilities, we need to find a common denominator. The common denominator for 2, 4, 6, and 12 is 12. So, we can rewrite the probabilities as:

Probability of selecting a red marble = 6/12

Probability of selecting a blue marble = 3/12

Probability of selecting a green marble = 2/12

Probability of selecting a yellow marble = 1/12

Since the probability of selecting a red marble is the highest among all the colors, it is the most likely color to be chosen.

Therefore, by probability the answer will be red marble.
