Answer:

20.8

Step-by-step explanation:

tan = opposite/ adjacent

opposite = tan * adjacent

opposite = 1,482561 * 14 = 20,755854

Answer:

20.8 =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan 56 = x/ 14

14 tan 56 =x

20.75585356 =x

To the nearest tenth

20.8 =x

Answer:Extract the formula for the height of a rectangular-based pyramid using your knowledge of algebra. H = V / (L x W) / 3. For instance, V = 60 cubic cm, L = 4 cm and W = 6 cm.

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

24 = 3x - 12 (opposite sides of a parallelogram are equal)

24 + 12 = 3x

36 = 3x

36/3 = x

12 = x

Answer:

x=13

Step-by-step explanation:

The parallel sides on a parallelogram are equal, therefore you must find a number that would satisfy the requirement for equality in the sides' length

So lets get started by finding out what number would be 24 after 12 has been subtracted from it.

24+12=36

Now we need to find out how to get 36 from 3x

36/3=13

13.

x is 13.

Now lets check that our answer is right

13x3=36

so far so good.

36-12=24

That checks out.

24=24.

Answer:

Step-by-step explanation:

Expression on the board :

[tex]12.2x + 50.6 y + 3(1.4x - 2.6y)\\\\= 12.2x + 50.6y + 4.2x - 7.8y\\\\= 16.4x + 42.8y[/tex]

Expression by the student :

Expression 1 :

[tex]4 ( 4.1x + 10.7 y ) \\\\= ( 4 \times 4.1x ) + ( 4 \times 10.7 y)\\\\= 16.4x + 42.8y\\\\[/tex]

The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.

Expression 2 :

[tex]2 ( 6.1x + 25.3 y + 2.1x -3.9y)\\\\= 2 ( 8.2x + 21.4y)\\\\=( 2 \times 8.2x ) + (2 \times 21.4y)\\\\= 16.4x + 42.8y[/tex]

The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.

Answer:

(3, -1), 7

Step-by-step explanation:

To find the center of this circle:  compare the given equation

(x - 3)^2 + (y + 1)^2 = 7^2   to the standard equation of a circle with center at (h, k):

(x - h)^2 + (y -k)^2 = r^2

From this comparison we see that the center is at

h = 3 and k = -1, and also that r must be 7:    (3, -1), 7

IQR is shorthand for interquartile range

=========================================================

Explanation:

The original list is {84,75,90,87,99,91,85,88,76,92,94}

It sorts to {75,76,84,85,87,88,90,91,92,94,99}

Pick out the middle most value, which is 88 in slot 6. A quick way to get here is to see that there are n = 11 values in this set. So n/2 = 11/2 = 5.5 which rounds to 6, and that tells us the slot number where the median is held. If n is an even number, then you'll need to use the midpoint formula for the two middle-most items.

After we determine the median is 88, we split the sorted data set as follows:

L = {75,76,84,85,87}

U = {90,91,92,94,99}

Everything in set L is below the median. L for lower.

Everything in set U is above the median. U for upper.

Sets L and U have 5 items each. Note that 5+1+5 = 11 = n.

-------------

The median of set L is 84, so Q1 = 84

The median of set U is 92, so Q3 = 92

Q1 and Q3 are the first and third quartiles respectively. Subtracting them gets us the IQR (interquartile range)

IQR = Q3 - Q1

IQR = 92 - 84

IQR = 8

The IQR helps give us a sense how spread out the data set is. It's similar to the range, which is found by range = max - min. The larger the (interquartile)range, the more spread out the data set will be.

Step-by-step explanation:

Answer:

Solution given:

∆ ABE is similar to ∆ ACD

since their side will be proportional

AB/AC=AE/AD

AB/(AB+BC)=AE/(AE+ED)

63/(63+7)=(7x-40)/(7x-40+18)

9/10=(7x-40)/(7x-22)

doing crisscrossed multiplication

9(7x-22)=10(7x-40)

63x-198=70x-400

400-198=70x-63x

202=7x

x=202/7 or 28.85units.

Answer:

[tex]x=28\frac{6}{7}[/tex]

[tex]x \approx 28.857[/tex]

Step-by-step explanation:

It is given that lines (BE) and (CD) are parallel, thus (<AEB) and (EDC) are congruent by alternate interior angles theorem. Moreover, (<A) is shared between the two triangles, therefore it is also congruent. Hence, triangles (ABE) and (ACD) are similar by (angle-angle) similarity.

Side (AD) is composed of segments (AE) and (ED), therefore one can find the total measure of segment (AD):

AD = AE + ED

AD = 7x - 40 + 18

AD = 7x - 22

Side (AC) is made of segments (AB) and (BC), thus one can find the total length of the side (AC) by adding these two segments:

AC = AB + BC

AC = 63 + 7

AC = 70

When two triangles are similar, the ratios of the sides are equal. Therefore, one can make the following statement:

[tex]\frac{AE}{AD}=\frac{AB}{AC}[/tex]

Substitute,

[tex]\frac{7x-40}{7x-22}=\frac{63}{70}[/tex]

Cross products,

[tex]70(7x-40)=63(7x-22)[/tex]

Distribute,

[tex]490x-2800=441x-1386[/tex]

Inverse operations,

[tex]490x-2800=441x-1386[/tex]

[tex]49x-2800=-1386[/tex]

[tex]49x=1414[/tex]

Answer:

(b) $ 1966.8

Step-by-step explanation:

Principal, P= $ 10000

Rate of interest, r = 6 % per year

time, t = 3 years = 36 months

(a) Interest per  year

The amount is given by

[tex]A = P \times \left ( 1+\frac{r}{100} \right )^{t}\\\\A = 10000 \times \left ( 1+\frac{6}{100} \right )^{3}\\\\A = 10000 \times 1.191\\\\A = 11910.2[/tex]

Interest is given by = $11910.2 - $10000 = $ 1910.6

(b) interest per month

The amount is given by

[tex]A = P \times \left ( 1+\frac{r}{100} \right )^{t}\\\\A = 10000 \times \left ( 1+\frac{6}{1200} \right )^{36}\\\\A = 10000 \times 1.1967\\\\A = 11966.8[/tex]

Interest paid is = $ 11966.8 - $ 10000 = $ 1966.8

Answer:

Since -15/16 does not equal -16/15, the statement is verified/true.

Step-by-step explanation:

Plug in the numbers for the variable:

-3/4 ÷ 4/5 =/ 4/5 ÷ -3/4

Copy dot flip:

-3/4 × 5/4 =/ 4/5 × -4/3

Multiply numerators and denominators separately:

-3 × 5 / 4 × 4 =/ 4 × -4 / 5 × 3

-15 / 16 =/ -16/15

-15/16 =/ -16/15

-15/16 does not equal -16/15.

Answer:

89*

Step-by-step explanation:

To find the value of m<1, you need to find the angle right next to it (the third interior angle that isn't labeled).

To find that angle (let's call it x), we have to use an equation.

Since a triangle has a sum of 180* for the interior angles in it, then we can use that to solve for x.

x + 53 + 36 = 180

x + 89 = 180

x = 91

Now to find m<1, we need to use the supplementary angles theorem.

Since m<1 and x are supplementary angles, the sum of those angles would be 180. Using this, we can create an equation.

x + m<1 = 180

91 + m<1 = 180

m<1 = 89

Hence, m<1 is 89*!

Answer:

x = 46.7°

Step-by-step explanation:

We are given:

1.) Angle x

2.) Side opposite to angle x

3.) Hypotenuse

We have to find angle x, therefore Sin ratio would be used;

Sin(x) = Opposite / hypotenuse

Sin(x) = 4 / 5.5

x = Sin⁻¹(4/5.5)

x = 46.7°

Hope this helps!

Answer:

12s - 16t

Step-by-step explanation:

2(3s + t) + 2(3s - 9t)

6s + 2t + 6s - 18t

12s + 2t - 18t

12s - 16t

Answer:Perimeter of the rectangle =(12s -16t)centimeters.

Step-by-step explanation:

The perimeter of a rectangle is given as 2(l+w)

Given that  width of the  rectangle=(3s+t)centimeters. and

Length of the  rectangle=(3s-9t)centimeters.

Solving we have

Perimeter= 2(l+w)

Perimeter=2(3s+t +3s-9t)

Perimeter=2(3s+3s -9t+t)

Perimeter=2(6s-8t)

Perimeter=(12s -16t)centimeters.
