Answer:

x = 35 degrees.

Step-by-step explanation:

cos x = sin(20 + x)

Using the identity cos x = sin(90 - x):

20 + x = 90 - x

2x = 70

x = 35 degrees (answer).

Answer:

Value of x is 35°.

Step-by-step explanation:

Given:

cos x = sin ( 20 + x )

To find: Value of the x.

We know that [tex]sin\,(90-\theta)=cos\,\theta[/tex]

Consider,

cos x = sin ( 20 + x )

sin ( 90 - x ) = sin ( 20 + x )

Comparing both sides,

90 - x = 20 + x

-x - x = 20 - 90

-2x = -70

x = 35°

Therefore, Value of x is 35°.

Answer:

Part 1) [tex]HD=\sqrt{105}\ units[/tex]

Part 2) [tex]JD=2\sqrt{34}\ units[/tex]

Part 3) [tex]KD=6\sqrt{2}\ units[/tex]

Step-by-step explanation:

step 1

Find the length HD

In the right triangle HDF

Applying the Pythagoras Theorem

[tex]FD^{2} =HF^{2} +HD^{2}[/tex]

substitute the values and solve for HD

[tex]19^{2} =16^{2} +HD^{2}[/tex]

[tex]HD^{2}=19^{2}-16^{2}[/tex]

[tex]HD^{2}=105[/tex]

[tex]HD=\sqrt{105}\ units[/tex]

step 2

Find the length JD

In the right triangle JDF

Applying the Pythagoras Theorem

[tex]FD^{2} =JD^{2} +FJ^{2}[/tex]

we have

[tex]FD=19\ units[/tex]

[tex]FJ=JG=15\ units[/tex] ----> because JD is a perpendicular bisector

substitute the values and solve for JD

[tex]19^{2} =JD^{2} +15^{2}[/tex]

[tex]JD^{2}=19^{2}-15^{2}[/tex]

[tex]JD^{2}=136[/tex]

[tex]JD=\sqrt{136}\ units[/tex]

[tex]JD=2\sqrt{34}\ units[/tex]

step 3

Find the length KD

In the right triangle KDG

Applying the Pythagoras Theorem

[tex]GD^{2} =KD^{2} +GK^{2}[/tex]

we have

[tex]GD=FD=19\ units[/tex]

[tex]GK=17\ units[/tex]

substitute the values and solve for KD

[tex]19^{2} =KD^{2} +17^{2}[/tex]

[tex]KD^{2}=19^{2}-17^{2}[/tex]

[tex]KD^{2}=72[/tex]

[tex]KD=\sqrt{72}\ units[/tex]

[tex]KD=6\sqrt{2}\ units[/tex]

Answer: 5

Step-by-step explanation: If Mike Only has $100 To Spend On Games, He Can Buy 5 Games Because We Multiply 20 By 5 To Get A Product Of 100.

Therefore, Mike Can Afford 5 Games With No Money Left.

Have A Fantastic Day!

Be Safe,

Eric

Mike can afford to buy 5 $20 games.

To determine how many $20 games Mike can afford to buy with $100, we divide the total amount of money he has by the cost of one game.

Total money Mike has = $100

Cost of one game = $20

Number of games Mike can afford = Total money / Cost of one game

Number of games Mike can afford = $100 / $20

Number of games Mike can afford = 5

Therefore, Mike can buy 5 games with $100.

Answer:

5^2

Step-by-step explanation:

Answer:

x = ±sqrt(26)

Step-by-step explanation:

x^2 = 26

Take the square root of each side

sqrt(x^2) = sqrt(26)

x = ±sqrt(26)

This cannot be simplified any further

[tex](\frac{f}{g})(x)=\frac{x^{2} +2x-3}{x^2-9}[/tex]  since x = 4, you plug in 4 into the x's in the equation

[tex](\frac{f}{g} )(4)=\frac{(4)^2+2(4)-3}{(4)^2-9} = \frac{16 + 8 - 3}{16 - 9}[/tex]  Simplify

[tex]\frac{21}{7} =3[/tex]    

so [tex](\frac{f}{g})(4)=3[/tex]

(f + g)(x) = (x² + 2x - 3) + (x² - 9)     Plug in 4 for x

(f + g)(4) = 4² + 2(4) - 3 + (4)² - 9

(f + g)(4) = 16 + 8 - 3 + 16 - 9 = 28

Answer:

Point D lies on the circumference of the unit circle

Step-by-step explanation:

Use the unit circle formula x^2 + y^2 = 1 plug the possible answer choices into this formula and determine  which one is true.

D(3/4,root 7/4) lies on the circumference of the unit circle , Option D is the correct answer.

A unit circle is a circle with 1 unit radius and the center is at origin .

The equation of a unit circle is x ² + y² =1

The points given are

A(4,3) B(1/2,1/5) C(0.6,0.7) D(3/4,root 7/4).

To check if they lie on the circumference of a unit circle , They have to be substituted in the equation of unit circle.

Point A

4 ² + 3² =1

16+ 9 ≠ 1

Point B

(1/2) ² + (1/5)² =1

(1/4) + (1/25) = 1

29/100  ≠ 1

Point C

(0.6) ² + (0.7)² =1

0.85 ≠ 1

Point D

(3/4)² + (√7/4)² =1

(9/16) + (7/16) = 1

1 = 1

Therefore , Option D,  D(3/4,root 7/4) lies on the circumference of the unit circle.

Given : The probability for success of an event is P(A), and the probability of success of a second event is P(B).

To find : What is the  probability of both events occurring, in that order?        

Solution :

Answer:

25 1/2 × 5 - 3 = 5x

51/2 × 5 - 3    = 5x

255/2 - 3       = 5x

255/2 - 6/2   = 10x/2

255 - 6          = 10x

249               = 10x

x                    = 249/10 = 24.9

The value of x in the equation [tex]25\frac{1}{2} * 5 -3 = 5x[/tex]  is x=24.9

Given:

Find:

Solution:

The given equation is [tex]25\frac{1}{2} * 5 -3 = 5x[/tex]

Now, solving the equation, we get;

[tex]25\frac{1}{2} * 5 -3 = 5x[/tex]

[tex]\frac{51}{2} *5 - 3 =5x[/tex]

Now, multiplying the 51/2 with 5, we get;

[tex]\frac{255}{2} - 3 = 5x[/tex]

Now, we will take lcm and we get;

[tex]\frac{255-6}{2} = 5x[/tex]

[tex]\frac{249}{2} = 5x[/tex]

Now, multiplying with 2 on both sides of the equation, we get;

249 = 10x

Now, dividing by 10 into both sides of the equation, we get;

x = 24.9

Hence, the value of x in the equation [tex]25\frac{1}{2} * 5 -3 = 5x[/tex] is x=24.9

Answer:

4153

Step-by-step explanation:

(x-3)/10 + 3000 = x-73

(x-3)/10 = x - 3738

x-3 = 10x - 37380

 x = 10x - 37377

-9x = -37377

 x = 4153

: P

Answer:

4153

Step-by-step explanation:

Let the original number be x

First, you subtract 3 from the original number. This removes 3 from the last digit, but leaves a zero there.

Now to remove the zero, you divide by 10.

Finally, to put the 3 at the first position, you add 3000.

Now Moving the last digit, 3, to the first position the number becomes :[tex]\frac{x-3}{10}+3000[/tex]

We are given that the number will decrease by 738.

A.T.Q

[tex]\frac{x-3}{10} + 3000 = x-738[/tex]

[tex]\frac{x-3}{10}= x - 3738[/tex]

[tex]x-3 = 10x - 37380[/tex]

[tex]x = 10x - 37377[/tex]

[tex]-9x = -37377[/tex]

[tex]x = 4153[/tex]

Hence the original 4-digit number is 4153.

Answer:

25 in.

Step-by-step explanation:

Since we know geckos are 2/5 of an Iguana's length, we need to find the length of 1/5.

So if 10 in. is 2/5, 5 in, is 1/5.

Now, since the denominator is 5, we multiply 5 in. by 5.

5x5=25 in.

25 in. is the length of an average Iguana.

Answer:

Perimeter=737 feets

Area=13542.6 ft²

Step-by-step explanation:

Well assuming that a,b,c are the three sides of the triangle and h is the height then;

Perimeter=distance around the figure

P=164+221+352= 737 feet

Area of a triangle given three sides is calculated using the formulae;

Area=√s (s-a) (s-b) (s-c) where  s=(a+b+c)/2

Finding s;

s=(164+221+352)/2 =368.5 feet

Finding the area

A= √ 368.5 (368.5-164) (368.5-221) (368.5-352)

A=√368.5 (204.5) (147.5) (16.5)

Answer:

value of t is greater than equal to -9 / 28.

Step-by-step explanation:

Given Quadratic Polynomial :  tx² + 3x - 7 = 0

Also, It has real solutions.

Standard Quadratic equation, is ax² + bx + c = 0

here, Determinant, D = b² - 4ac

decides nature of the roots.

if D < 0 , roots / solutions are complex

if D = 0 , roots are real and equal.

if D > 0 , roots are real and different.

As given roots are real solutions.

Means Dis either equal to 0 or greater than 0

when D = 0

we have, 3² - 4 × t × (-7) = 0

               9 + 28t = 0

               t = -9 / 28

when D > 0

we have, 3² - 4 × t × (-7) > 0

               9 + 28t > 0

               t > -9 / 28

Therefore, value of t is greater than equal to -9 / 28.

The radius is 100.

C = [tex]200\pi[/tex]

to figure out the percentage, you’ll have to do 78 divided by 120 (because it’s 78/120) which is 0.65. now, you’ll have to multiply by 100, so her percentage is 65%.
