The Ratio of number x and four added by two

Answer:

72.4

Step-by-step explanation:

According to the given triangle the value of sin A = 4/5

In a right-angled triangle, the sin of an angle is equal to the ratio of the opposing side to the hypotenuse according to the sin theta formula.

Sin A = Opposite angle / hypotenuse= 4/5

There are about six trigonometric ratios—sine, cosine, tangent, cosecant, secant, and cotangent—which describe the many configurations that can be made in a right-angled triangle.

Trigonometry can only be used to solve a side of a right-angled triangle when the lengths of the other two sides and the angle of a side are already known. Before utilizing algebra to determine the value for the unknown side, one must first select a ratio that includes both the unknown and the given sides.

We are aware that the angle-length relationship in right-angled triangles will be covered in trigonometry.

Given that,

In the picture there is a triangle with ABC angles.

Sides AB=5, BC=3, CA=4

Trigonometric ratios, which contain the values of all trigonometric functions, are based on the ratio of sides of a right-angled triangle. The ratios of a right-angled triangle's sides with regard to a certain acute angle are known as its trigonometric ratios.

The right triangle's three sides are as follows:

Hypotenuse (the longest side)

Perpendicular (opposite side to the angle)

Base (Adjacent side to the angle)

According to the sin theta formula, the sin of an angle in a right-angled triangle is equal to the ratio of the opposite side to the hypotenuse.

Sin A = Opposite side / hypotenuse

SinA=3/5

Therefore, SinA=3/5.

Answer:

3.0625 seconds

Step-by-step explanation:

From the question,

✓She slides at a rate of 8 m/s downward

✓after 3 seconds is 5 m off of the ground

We can calculate the the number of seconds she will use to get to the ground by

Velocity= distance/time

Time= distance/ velocity

=5/8 seconds

=0.625seconds

To know how many seconds it will take her to slide to the ground from the top can be calculated as

( 3seconds + 0.625 seconds)

= 3.0625 seconds

2x (29 +28y )

That is the answer

Using proportions, it is found that you would expect to see camels, wombats, and kangaroos for the next 57.17 miles.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

Each km has 0.621371 miles, hence:

92 km = 92 x 0.621371 = 57.17 miles.

You would expect to see camels, wombats, and kangaroos for the next 57.17 miles.

Step-by-step explanation:

The ordered pairs that shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after can starts dispensing water: {(1, 7.8), (2, 7.6), (3, 7.4)}

For given question,

A watering can dispenses water at the rate of 0.20 gallon per minute.

The original volume of water in the can was 8 gallons.

We need to find the ordered pairs that shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after can starts dispensing water.

The ordered pair is of the form (x, y) means the first coordinate is time in minutes and the second coordinate is the volume of water in the can in gallons.

Initially, for x = 0 minutes, y = 8 gallons

After 1 minute, the amount of water in can is 8.0 - 0.20 = 7.8 gallons.

So, the ordered pair of the form (time, volume of water) are:  {(1, 7.8), (2, 7.6), (3, 7.4)}

Therefore, the ordered pairs that shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after can starts dispensing water: {(1, 7.8), (2, 7.6), (3, 7.4)}

Answer:

C. 6.8, because |6.8|= 6.8

Step-by-step explanation:

The magnitude of a directed number is a property that turns the number to a positive of its value. Thus, the magnitude of a negative number equals its positive value. Examples:

Find the magnitude of the following numbers:

i. -20

ii. 10

iii. -5

iv. 2

The magnitudes of the numbers can be expressed as:

i. |-20| = 20

ii. |10| = 10

iii. |-5| = 5

iv. |2| = 2

Therefore, the magnitude of 6.8 = 6.8, because |6.8|= 6.8.

Step-by-step explanation:

just substitute them in the x and y variables.

Answer:

x=3 , y=-6

Step-by-step explanation:

 x − 2y = 15 is one of the problems. so x in this problem stays as 3, and double of y is -12, so if we take 3 - (-12) or more simply, 3+ 12, which is 15.

2x + 4y = -18  is the other problem. so x is doubled making x equal to 6, and four times y, or -6, is equal to -24 . So bringing the while thing together, 6 + -24, or put more simply, 6-24=-18, making the answer

x=3 , y=6

Answer: A equation that could have "x= -3" as a solution could be "235x - 18 = -723".

Answer:

The correct answer is no.

Step-by-step explanation:

If a number is a factor of another number, that means that it can be equally divided into it evenly.

I know that 3 x 20 = 60, and 73 - 60 = 13.

Since 3 is not a factor of 13, it is also not a factor of 73.

Answer:

y = 4

or (0, 4)

Step-by-step explanation:

intersecting the y-axis is basically when x is equal to 0.

1.5(0) +4.5y = 18

y = 4

So your y-intersect is (0, 4) and thats when it intersects the y-axis.

Answer:

See the picture attached. The purple line is y=3x+6 and the red line is y=3x+1.

Step-by-step explanation:

When graphing lines, start with the y-intercept and then use the slope to plot points to help you draw the line.

The equations are in y=mx+b form, where mx is the slope and b is the y-intercept. To get the points, plug in a number where x is. Whatever result you get is the y coordinate for that number.

For example, on the graph in the picture 3(1)+1 = 4. Using that, you would plot the point (1,7).

Answer:

Janet hiked 18 miles during the past week.

Step-by-step explanation:

Length of hiking trail = 3.6 miles

Number of days she hiked during past week = 5 days

We need to find how many miles has Janet hiked in the past week?

We will multiply length of trail with number of days she hiked that trail

Miles Janet hiked in the past week = 3.6 * 5

                                                           = 18 miles

So, Janet hiked 18 miles during the past week.

Let x be the original price of a lawn mower,

If the hardware store is having a 15% off sale on lawn mowers this weekend, the amount discounted is expressed as;

= 15 % of x

= 0.15 of x

= 0.15x

Final sales price = Original price - discounted price;

Final sales price = x - 0.15x

Factor out x;

x - 0.15x = x(1 - 0.15)

Hence the correct equations are (x - 0.15x)  and x(1.00 - 0.15)
