Answer:

73.5

Step-by-step explanation:

Please find the complete question in the attached image

Remember the notation SOHCAHTOA

We would be using cos because we have been given the hypotenuse and we are to determine the adjacent value

cos 37 = adjacent / hypotenuse

cos 37 = adjacent / 92

0.7986 = adjacent / 92

adjacent = 0.7986 x 92 = 73.5

Answer:

[tex]x\approx 24.0,\\y\approx 46.4[/tex]

Step-by-step explanation:

Let the height of the largest triangle marked be [tex]h[/tex]. We can set up the following equation:

[tex]\sin 30^{\circ}=\frac{h}{34},\\h=34 \sin 30^{\circ}=17[/tex] (if you're unfamiliar with trig, this is likely introduced to you as 30-60-90 triangle rules)

This height is also a leg of a 45-45-90 triangle, as marked in the diagram. From the isosceles-base-theorem, the other leg of this triangle must also be equal to [tex]h[/tex]. Therefore, we can use the Pythagorean theorem to solve for [tex]x[/tex]:

[tex]17^2+17^2=x^2\\x^2=\sqrt{17^2\cdot 2},\\x=17\sqrt{2}\approx \boxed{24.0}[/tex] (you can also use trig or 45-45-90 triangle rules which are derived from the Pythagorean theorem)

Segment [tex]y[/tex] consists of two shorter segments, a left segment and a right segment. We've already found that the left segment is equal to 17. To find the right segment we can use trig, the Pythagorean theorem, or 30-60-90 triangle rules (derived from the Pythagorean theorem):

Using Pythagorean Theorem:

[tex]y_{right}=\sqrt{34^2-17^2}\approx \boxed{29.4}[/tex]

Therefore, we have:

[tex]y=17+29.4=\boxed{46.4}[/tex]

Answer:

20

Step-by-step explanation:

Answer:

16 meters

Step-by-step explanation:

[tex] In\: \odot F, \: \overline {RS} [/tex] is tangent to the circle at point R and FR is radius.

[tex] \therefore RF\perp RS[/tex] (Tangent radius theorem)

[tex] \therefore m\angle FRS = 90\degree [/tex]

So, [tex] \triangle FRS[/tex] is right angled triangle and FS is its hypotenuse.

Let FR = FT = r

FS = FT + ST = r + 9

Now, by Pythagoras theorem:

[tex]FR^2 + RS^2 = FS^2 \\ \therefore r^2 + (15)^2 = (r + 9)^2 \\ \therefore \cancel{ r^2} +225 = \cancel{ r^2} + 18r + 81\\ \therefore \: 225 = 18r + 81 \\ \therefore \: 225 - 81= 18r \\ \therefore \: 144= 18r \\ \therefore \: r = \frac{144}{18} \\ \therefore \: r =8 \: m\\ \implies \: d = 2r = 2(8) = 16 \: m[/tex]

Thus, the diameter of the fountain is 16 meters.

Answer:

13years

Step-by-step explanation:

Using the formula for calculating the compound interest expressed as;

A =P(1+r)^n

P = 12000

rate r  = 4% = 0.04

Amount after 4 years A = 20,000

Substitute into the formula and solve for p

20,000 = 12,000(1+0.04)^t

20,000/12000 = (1.04)^t

1.67 = (1.04)^t

Take the ln of both side

ln1.67 = ln(1.04)^t

ln1.67 = t ln 1.04

t = ln1.67/ln1.04

t = 0.5108/0.0392

t = 13.03

hence it will take approximately 13years to reach 20,000

Answer:

x = 11.1

Step-by-step explanation:

Cosine theta = adjacent/hypotenuse

cos 42 = x/15

x = 15 cos 42

x = 11.1

Answer:

Company one charges $11 + $0.16 per min.

Then if you talk for x minutes, the cost will be:

C₁(x) = $11 + ($0.16 per min)*x

For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:

C₂(x) = $20 + ($0.11 per min)*x

Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.

C₁(x) = C₂(x)

$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x

($0.16 per min)*x - ($0.11 per min)*x = $20 - $11

($0.05 per min)*x = $9

x = $9/($0.05 per min) = 180 mins

If you speak for 180 minutes, the cost is the same in both companies.

Answer:

x=9

Step-by-step explanation:

a²+b²=c²

x²+6²=(√117)²

x²+36=117

x²=81

x=9

Answer:

3[tex]\sqrt{17}[/tex] or 12.37 cm

Step-by-step explanation:

use the Pythagorean Theorem:

6² + [tex]\sqrt{117}[/tex]² = x²

36 + 117 = x²

x² = 153

x = [tex]\sqrt{153}[/tex] which is [tex]\sqrt{9}[/tex][tex]\sqrt{17}[/tex] or 3[tex]\sqrt{17}[/tex]

in decimal form, 'x' is approx 12.37

Answer:

w=129.8

Step-by-step explanation:

w + 125.2 = 255​

                  -125.2

w=225-125.2

w=129.8

Answer:

Hope this helps please mark me as branlist.

Step-by-step explanation:

Subtract 125.2 from both sides:

w=125.2=255

w=125.2-125.2=255-125.2

w=255-125.2

w=129.8

Answer:

y = (-1/5)x + 1

Step-by-step explanation:

The slope of this perpendicular line is the negative reciprocal of the slope of the given line y = 5x + 4:  -1/5.

Applying the slope-intercept form of the equation of a line, we get:

2 = (-1/5)(-5) + b, or:

2 = 1 + b

Therefore, b = 1 and the desired equation is:

y = (-1/5)x + 1

Answer:

39.98

Explanation:

39.98015​

0 < 5, so 2nd decimal stays at 8

Answer:39.98

Step-by-step explanation:

Hey! I’m not exactly sure what you’re asking, but if the question is how to write that number in only two decimal places, it would be 39.98. We would round it up or down in the hundredths place because that is the second decimal place. Since the number behind the 8 is 0, we can’t round up or down so we would just leave it how it is and cut off the rest.

Hope this helped! :D

Answer:

c)4x^2-4x+7

Step-by-step explanation:

Sumando los polinomios 4x2-10x-5 y 6x + 12, tendremos:

 4x2-10x-5

        6x + 12

4x ^ 2- 4x + 7

En esta pregunta, los términos semejantes se añaden con los términos semejantes. Cuando se suma -10x a + 6x, se obtiene -4x porque 10x tiene signo negativo y 6x tiene signo positivo. Los diferentes signos se restan y el signo del término más grande se coloca al lado del término resultante.

De manera similar, se resta 5 de 12 y obtenemos 7.

Los términos que están solos siguen siendo los mismos, sus potencias o coeficientes no cambian después de la suma o la resta.

entonces la mejor opción es la opción C

English

Adding the Polynomials 4x2-10x-5 and 6x + 12, we will have:

 4x2-10x-5

        6x+ 12    

4x^2- 4x+7    

In this  question like terms are added with the like terms. When -10x is added to +6x it gives -4x because 10x has negative sign and 6x has positive sign. Different signs are subtracted and the sign of the bigger term is placed beside the resulting term.

Similarly 5 is subtracted from 12 and we get 7.

The terms which are alone remain the same their powers or co efficients do not change after addition or subtraction.

so the best choice is option C

Answer:

V - 1099.55742876

SA - 769.690200129

Step-by-step explanation:

The volume of a cone is denoted by the formula:

V = 1/3 * h * pi * r^2

We can substitute in the values we are given:

V = 1/3 * 10.5 * pi * 10^2

V = 3.5 * 100 * pi

V = 350pi

This is about: 1099.55742876

The formula for the surface area of a cone is:

SA = pi * r^2 + pi * r * s

We can substitute what we have:

SA = pi * 10^2 + pi * 10 * 14.5

SA = 100 pi + 145 pi

SA = 245 pi

This is about: 769.690200129

Answer:

x = 34

Step-by-step explanation:

Given

x + 38 = 72 ( subtract 38 from both sides )

x = 34

Answer:

X=34

Step-by-step explanation:

Well, what you can do is bring the 38 to the other side and make it negative so you can subtract 38 with the 72. The 72-38 is= 34 and so x= 34

x+38=72

x=72-38

x=34

Answer:

4.25

Step-by-step explanation:

Since this is a parallelogram, the parallel sides have the same value.

And since the perimeter of a parallelogram is all of the sides combined, this means

WR + RJ + JS + WS, or

5x + 5x + 3x + 2 + 3x +2 = 16x + 4

The perimeter is 16, so

16x + 4 = 16

16x = 12

x = 0.75

Substitute into 3x + 2, or WS.

2.25 + 2 = WS

WS = 4.25

Step-by-step explanation:

perimeter of parallelogram =16

so value of WS=3x+2
