if 3x=5 what’s 3^4x=

Answer: X= 50

Step-by-step explanation:

To be able to solve this, you must identify vertical angles, as well as a linear pair.

The angle next to the angle of 103 is in a linear pair. This means they both add up to 180.

180- 103 = 77. The angle that is next to the angle of 103 is 77.

You have two angles in a triangle. You can use the triangle sum theorem, which states that all angles of a triangle add up to 180.

180- (53+ 77)= the third angle

180- 130 = 50 (the third angle)

The third angle of the triangle is a vertical angle in relation to x. All vertical angles are equal. This means that x= 50°.

The total earning of the Brent for watch group of 7 preschool children is $28.75.

For the given question;

Let 'x' be the number of hours Brent watched the preschool children.

The rate of one hour is $7.25.

The number of hours from 9:00 am to noon is 3 hours.

Let 'y' be the number of children.

The price per child is $1.00.

Thus, the formation of linear equation will be;

= 7.25x + 1.00y

For x = 3 hours and y = 7 child.

= 7.25×3 + 1.00×7

= 21.75 + 7

= 28.75

Thus, the total earnings of the Brent for today is $28.75.

The linear function that represents the trend line is given by:

C(f) = 50f + 100.

A linear function is defined according to the following rule:

y = mx + b.

In which the parameters m and b are defined as follows:

For the trend line, when fat = 0, calories = 100, hence the intercept of the function is given by:

b = 100.

When the fat increases by 2, the calories increase by 100, hence the slope is given by:

m = 100/2 = 50.

This constant rate of change is true for the entire trend line, hence it represents a linear function.

The function is given by:

Annual Medical cost = 1269.86

monthly premium cost to Ronald for the Blue Shield plan = $48.48.

For all doctor office visits, prescriptions, and major medical charges, Ronald will be responsible for 35 percent and the insurance company will cover 65 percent of covered charges.

The annual deductible cost = $630.

Ronald decided to review his medical bills from the previous year to see what costs he had incurred and to help him evaluate his choices. He visited his general physician 6 times during the year at a cost = $105 for each visit.

He also spent $71 and $95 on two prescriptions during the year.

= (Monthly premium cost × 12) + Deductible cost + (Coinsurance percent × Coinsurance expenses)

= (48.48 x 12) + 630 + (0.35 x 166)

The value of ∠1 is 140°, ∠3 is 65° and ∠5 is 115° after using the values of angles given in the figure.

According to the question,

We have a figure where some of the angles are given and we have to find angles which are numbered from 1 to 5.

In solving this question, we need to keep in mind two things. First is that the angle made on a straight line is always 180° (this will be referred to as the former part). Second is that the exterior angle of a triangle is equal to the sum of the opposite interior angles of that triangle (it will be referred to as the latter part).

So, to find ∠1, we will use the latter part.

∠1 = 80°+60°

∠1 = 140°

Now, in order to find ∠2 we will use the former part (angle made on a straight line).

∠1 + ∠2 = 180°

140° + ∠2 = 180°

∠2 = (180-140)°

∠2 = 40°

Now, to find ∠3, we will use the latter part.

∠2 + ∠3 = 105° (105° is an exterior angle)

40° + ∠3 = 105°

∠3 = (105-40)°

∠3 = 65°

Now, to find ∠4,  we will use the former part.

∠4 + 105° = 180°

∠4 = (180-105)°

∠4 = 75°

Now, after looking at the figure, it can be clearly seen that ∠5 is an exterior angle.

So, we have:

∠5 = ∠4 + 40°

∠5 = 75° + 40°

∠5 = 115°

Hence, the value of ∠1 is 140°, ∠3 is 65° and ∠5 is 115°.

If we solve  4x-3y=3, -8x +6y=-6 by substitution or elimination, we will have x=3/4 and y=0

We have the following simultaneous equations:

4x-3y=3.....................(i)

-8x+6y=-6..................(ii)

We solve using substitution:

Make x the subject of formula in equation(i):

4x=3+3y

x=(3+3y)/4

Now, replace the value of x in equation(ii)

-8x+6y=-6, and x=(3+3y)/4

-8((3+3y)/4)+6y=-6

-2(3+3y)+6y=-6

-6-6y+6y=-6

y=0

The average distance that the airplane covered in three flights is 2036 kilometers, time in trip from Hongkong to Manila is 1.468 hours, time in trip from Singapore to Manila is 3.146 hours, time in trip from Korea to Manila is 3.422 hours.

Given the distance that an airplane covered in three different trips:

Hongkong-Manila: 1116 kilometers, Singapore-Manila: 2391 kilometers,

Korea-Manila: 2601 kilometers.

We are required to find the average distance traveled by the airplane in the three trips, the time it took in each trip if the speed of airplane is 760 km/h and the trip that took the longest time to travel.

Average distance that airplane travelled in the three trips=(1116+2391+2601)/3

=6108/3

=2036 kilometers

We know that speed=distance/time.

Time=Distance/speed

Time in trip from Hongkong to Manila=1116/760=1.468 hours

Time in trip from Singapore to Manila=2391/760=3.146 hours

Time in trip from Korea to Manila=2601/760=3.422 hours

We can observe that the trip from Korea to Manila took longest time to travel.

Hence the average distance that the airplane covered in three flights is 2036 kilometers, time in trip from Hongkong to Manila is 1.468 hours, time in trip from Singapore to Manila is 3.146 hours, time in trip from Korea to Manila is 3.422 hours and the trip from Korea to Manila took longest time to travel.

The number of pumpkins that are not ripe is 15 pumpkins.

The number of spectators that were happy that UK won is 20 spectators

A fraction is a digit that is not a whole number. A fraction has a numerator and a denominator. An example of a fraction is 5/9. 5 is the numerator and 9 is the denominator.

Number of pumpkins that are not ripe = fraction of pumpkins that are not ripe x number of pumpkins

Fraction of pumpkins that are not ripe = 1 - fraction of pumpkins that are ripe

1 - 3/4 = 1/4

Number of pumpkins that are not ripe = 1/4 x 60 = 15 pumpkins

The slope of a line is equal to -8/3.

What is the slope of a line?

The ratio of the change in the y coordinate to the change in the x coordinate is known as a line's slope in mathematics. Y and X, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate.

Locate two locations along the chosen line and find their coordinates.

Find the y-coordinate difference between these two places (rise). Find the difference between the x-coordinates of these two points (run). Subtract the difference in y-coordinates from the difference in x-coordinates (rise/run or slope).

The slope is defined as the relationship between the rise, or vertical change, between two points and the change, or horizontal change, between the same two points.

Given that, coordinates are (2, 6) and (8, -10)

m = (-10 - 6)/8 - 2

m = -16/6 = -8/3
