A pole that is 2.8 tall casts a shadow that is 1.79 long. At the same time, a nearby building casts a shadow that is 42.25 long. How tall is the building? Round your answer to the nearest meter.

Answer:

7.6 units

Step-by-step explanation:

   Use law of sines

12 / sin C = b / sin B

sin B  * 12 / sin C = b

sin (32) * 12 / sin(57) = b = 7.6

The line which has a gradient of 6 is A. line A

To answer the question, we need to know what the gradient of a line is.

The gradient of a line is its slope. It is given by m = Δy/Δx where

Now, to find the line that has the gradient of 6, we see that the gradient

So, for a high value of gradient, we need

Also, since 6 is positive, the gradient for the line will be positive.

The only line that meets these criteria is line A.

So, the line which has a gradient of 6 is A. line A

By the ASA postulate, it can be said that the triangle ABC and triangle MRQ are congruent. Thus, option B is correct, Yes, they are congruent by either ASA or AAS.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Using Angle Sum Property, in ΔMRQ

<M + <R + <Q= 180

<M + 42 + 85 = 180

<M = 180 -42

<M= 53°

Now, In ΔMRQ and ΔABC  

<A= <R ,

<B = <M

AB = MR

Hence, By ASA criteria ΔMRQ ≅ ΔABC.

Thus, option B is correct, Yes, they are congruent by either ASA or AAS.

Step-by-step explanation:

Answer:

m = 0.875

Step-by-step explanation:

the 3 angles lie on a straight line and sum to 180° , that is

4m + 83 + 4m + 90 = 180

8m + 173 = 180 ( subtract 173 from both sides )

8m = 7 ( divide both sides by 8 )

m = [tex]\frac{7}{8}[/tex] = 0.875

Answer:

The third picture

Step-by-step explanation:

Solve for x in both equations

2x<6

Divide both sides by 2:

x<3

3x+2>-4

Subtract 2 from both sides:

3x>-6

Divide both sides by 3:

x>-2

There is this trick you can use when x is on the left side of the equation to find out which way to shade in you graph. Keep in mind this is only for the left side, it will not work if your variable is on the right.

When the symbol is facing left < then shade left, imagine it is pointing which way to shade. x<3 is represented by the 3 picture on the left. When the symbol is facing right > then shade right, again it is pointing which way to shade. x>-2 is represented by the 3 picture on the right.

The circles are not filled in because the symbol is < and > rather than [tex]\leq and \geq[/tex]. When it is greater than or equal to or less than and equal to (represented by the line under the symbol), then the circle is shaded in.

Answer:

There are 4 red counters

Step-by-step explanation:

1. Add the known decimals

    [tex]0.25+0.35+0.3=0.9[/tex]

2. Subtract that amount from one

      [tex]1-0.9=0.1[/tex]

3. multiply the result by 40

    [tex](40)(0.1)=4[/tex]

Hope this helps

Step-by-step explanation:

a probability is always desired cases / total cases.

from the table and given information we know :

there are 40 blue counters.

0.25 = 40/x

x being the total number of counters in the box.

x = 40 / 0.25 = 160

the sum of all probabilities must be 1 (the always true probability), as there are only counters in the box, and one of the 4 colors is always the result.

so,

1 = 0.25 + 0.35 + 0.3 + red-probability

1 = 0.9 + red-probability

red-probability = 1 - 0.9 = 0.1

0.1 = red counters / 160

red counters = 0.1 × 160 = 16

there are 16 red counters in the box.

The probability of a royal flush in a 5-card hand is 1/649740 or 0.0001539%.

The combination is a way of selecting a smaller number of sets from a larger number of sets in no particular order.

If selecting r items from a set of n items, in no particular order, we use combinations, using the formula:

nCr = n!/{r!(n - r)!}.

In the question, we are asked the probability of a royal flush in a 5 card hand.

The number of ways of selecting 5 cards from a deck can be computed using a combination, 52C5, as we have 52 cards in a deck, 5 cards are to be chosen and the order is not in concern.

52C5 = 52!/{5!(52 - 5)!} = 52!/(5!.47!) = (52*51*50*49*48)/(5*4*3*2*1) = 2598960.

The number of hands that make a royal flush is only 4. 4 from each suit.

Therefore, the probability = 4/2598960 = 1/649740 or 0.0001539%.

Therefore, the probability of a royal flush in a 5-card hand is 1/649740 or 0.0001539%.

The he statement d(k) + (k + 1) = d(k+1) is true for all natural numbers, n, by mathematical induction.

To prove that the statement is true for all natural numbers, n, we can use mathematical induction.

The statement we want to prove is that d(k) + (k + 1) = d(k + 1), where d(n) represents the total number of dots in a pattern of n squares.

Base Case (n = 1):

First, let's prove the statement for the base case, n = 1.

For n = 1:

d(1) + (1 + 1) = d(1) + 2

Now, consider a single square with 1 dot.

In this case, d(1) = 1.

So, we have:

1 + 2 = 3

Now, let's consider a pattern of 2 squares (n = 2).

The first square has 1 dot, and the second square has 2 dots. So, d(2) = 1 + 2 = 3.

So, the statement is true for n = 1.

Inductive Hypothesis (Assume true for n = k):

Now, assume that the statement is true for some arbitrary natural number k.

That is, assume that: d(k) + (k + 1) = d(k + 1)

Inductive Step (Prove true for n = k + 1):

To prove that the statement is true for n = k + 1.

d(k + 1) + (k + 2) = d(k + 2)

Now, consider a pattern of (k + 1) squares.

By the inductive hypothesis, assume that the statement is true for k squares:

d(k) + (k + 1) = d(k + 1)

Now, let's add one more square to the pattern.

This square will have (k + 2) dots.

So, the total number of dots in the pattern of (k + 1) squares plus the (k + 2) dots in the additional square is:

d(k + 1) + (k + 2)

And by the inductive hypothesis, d(k) + (k + 1) = d(k + 1).

Therefore:

d(k + 1) + (k + 2) = (d(k) + (k + 1)) + (k + 2) = d(k) + (k + 1) + (k + 2)

Now, simplify:

d(k + 1) + (k + 2) = d(k + 1) + (k + 1 + 1)

So, it is shown that for n = k + 1, d(k + 1) + (k + 2) = d(k + 1) + (k + 1) + 1.

Since it is assumed the statement to be true for k and proved it for k + 1, it is shown that the statement is true for all natural numbers, n, by mathematical induction.

Answer: If for every independent unit(aka x), you multiply the dependent unit by the same amount(aka y).

Step-by-step explanation:

EXAMPLE:

As you can see, each time x increases by unit, you multiply the y unit by 3.

As an example, if you increase x by 4, you multiply the y unit by 3^4 = 81.

If this pattern is consistent with your whole table, you have an exponential function.

Given that, ∠A and ∠B are supplementary angles. ∠A=(7x + 24)˚ and ∠B=(7x − 26)°.

Two angles are Supplementary when they add up to 180 degrees.

Now, ∠A+∠B=180°
