[tex] \huge{ \boxed{ \bold{ \tt{x = 30 \degree}}}}[/tex]

♨ Step - by - step explanation

☯ Given angles :

☯ To find :

✎ Set up an equation and solve for x :

Add the like terms. Remember that Only coefficients of like terms can be added or subtracted.

➺ [tex] \sf{3x \degree + 90 \degree = 180 \degree}[/tex]

Move 90° to right hand side and change it's sign

➺ [tex] \sf{3x \degree = 180 \degree - 90 \degree}[/tex]

Subtract 90° from 180°

➺ [tex] \sf{3x \degree = 90 \degree}[/tex]

Divide both sides by 3

➺ [tex] \sf{ \frac{3x \degree}{3} = \frac{90 \degree }{3} }[/tex]

➺ [tex] \boxed{ \sf{x = 30 \degree}}[/tex]

Answer: Children tickets cost 7.50

Adult tickets cost 12.50

Step-by-step explanation:

Let a represent adult tickets

Let c represent child tickets

On the first day she sells 6 adult tickets and 5 children tickets for total of 112.50. This can be written as:

6a + 5c = 112.50 ...... equation i

On the second day she sells 8 adult tickets and 4 children tickets for the total 130. This can be written as:

8a + 4c = 130 ....... equation ii

6a + 5c = 112.50 ...... equation i

8a + 4c = 130 ....... equation ii

Multiply equation i by 4

Multiply equation ii by 5

24a + 20c = 450 ........ equation iii

40a + 20c = 650 ......... equation iv

Subtract iii from iv

16a = 200

a = 200/16

a = 12.50

Adult tickets cost 12.50

From equation ii,

8a + 4c = 130

8(12.50) + 4c = 130

100 + 4c = 130

4c = 130 - 100

4c = 30

c = 30/4

c = 7.50

Children tickets cost 7.50

Using the concept of elimination, the cost of adult and children tickets are $12.5 and $7.5 respectively

Let :

Creating a system of equation thus :

6a + 5c = 112.50 - - - (1)

8a + 4c = 130 - - - - (2)

Multiply (1) by 4 and (2) by 5

24a + 20c = 450 - - - - (3)

40a + 20c = 650 - - - - (4)

Subtract

-16a = - 200

Divide both sides by - 16

a = 12.5

From (2) :

8(12.5) + 4c = 130

100 + 4c = 130

4c = 130 - 100

4c = 30

c = 7.5

Hence, the cost of adult and children tickets are $12.5 and $7.5

Answer:

6 to 2 2 to 6

Step-by-step explanation:

The ratios for the given situation are 3/7 and 4/7.

Given that, at a dinner party, two desserts are being served.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Six of the guests choose cheesecake, and eight of the guests choose apple pie.

So, the total number of guests = 6+8

= 14

Now, the ratio who chose cheesecake = 6/14

= 3/7

The ratio who chose apple pie = 8/14

= 4/7

Therefore, the ratios for the given situation are 3/7 and 4/7.

Step-by-step explanation:

The domain of a function such as this is the set of values that realistically may be given as input to the function. We know of no way to ride a motorcycle a negative number of miles, so the domain must be non-negative numbers.

In real life, the domain is likely non-negative integers.

Answer:

x = -1/8

Step-by-step explanation:

4^2x + 3 = 1 start by simplifying the equation

16x + 3 = 1 now subtract 3 on both sides

16x = -2 isolate the variable by dividing 16 on both sides

x = -1/8

Answer:

x = -1/8

Step-by-step explanation:

4^2x + 3 = 1

You want to try to get the x on one side by itself.

First step subtract 3 from both sides

4^2x + 3 -3 = 1 -3

so now it looks like 4^2x = -2

We know 4^2 is 4x4 which is 16.

16x= -2

Divide 16 by both sides.

x = -2 / 16

Reduce.

x = -1/8

Answer:

132 eggs

Step-by-step explanation:

7 chickens to 12 eggs; 77 chickens to x eggs

7/12 to 77/x

77/7 = 11

7/12 (11/11)

77/132

77 chickens to 132 eggs

If there are 77 chickens, and the ratio of chickens to eggs is 7 to 12, there are 132 eggs.

The number of eggs from the given ratio are 132.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, the ratio of chickens to eggs is 7 to 12.

There are 77 chickens.

Let x be the total number of chickens and eggs.

Now, 7/19 ×x=77

⇒ 7x=1463

⇒ x=209

Number of eggs =209-77

= 132

Therefore, the number of eggs are 132.

Answer:

The base is decreasing at 2 cm/min.

Step-by-step explanation:

The area (A) of a triangle is given by:

[tex] A = \frac{1}{2}bh [/tex]   (1)

Where:

b: is the base

h: is the altitude = 10 cm

If we take the derivative of equation (1) as a function of time we have:

[tex] \frac{dA}{dt} = \frac{1}{2}(\frac{db}{dt}h + \frac{dh}{dt}b) [/tex]

We can find the base by solving equation (1) for b:

[tex] b = \frac{2A}{h} = \frac{2*120 cm^{2}}{10 cm} = 24 cm [/tex]

Now, having that dh/dt = 1 cm/min, dA/dt = 2 cm²/min we can find db/dt:

[tex] 2 cm^{2}/min = \frac{1}{2}(\frac{db}{dt}*10 cm + 1 cm/min*24 cm) [/tex]

[tex]\frac{db}{dt} = \frac{2*2 cm^{2}/min - 1 cm/min*24 cm}{10 cm} = -2 cm/min[/tex]    

Therefore, the base is decreasing at 2 cm/min.

I hope it helps you!
