Find the value of y. Write your answer in decimal form. Round your answer to the nearest whole number.​

Answer:

Step-by-step explanation:

I would suspect you want to know what's wrong with the work.

AC is the hypotenuse. c = AC.

It should be done this way.

c = 6 in

b = 15 in

a = ?

a^2 + c^2 = b^2

a^2 + 6^2 = 15^2

a^2 + 36 = 225

a^2 = 225 - 36

a^2 =  189    

sqrt(a^2) = sqrt(189)

a = 13.75

Consider,

[tex]x + y = 46\\x = 46 -y[/tex]

→ (x+4) : (y +4) = 7:2

→ x+4/y+4 = 7/2

→ 46-y+4/y+4 = 7/2

→ 50-y/y+4 = 7/2

→7y +28 = 100-2y

→ 7y +2y = 100 -28

→ 9y = 72

→ y = 8

Now put y = 8 in eq(1) .

→ x = 46 - y

→ x = 46 - 8

→ x = 38

Three variable lines are drawn in the three dimensional coordinate system.

Three-dimensional coordinate system is also called rectangular coordinate system. The system has three reference axes named X, Y and Z axis which are perpendicular to each other.

The above three axes intersect at the origin.

In the analytical geometry, location of each point is represented by three coordinate system. They give mathematical statement by using three-dimensional space.

In order to plot in the three-dimensional plane, we need to determine the value of x, y and z. At first, we start from the origin and approach to the positive x direction if our x value is positive, otherwise we need to go to the negative x direction. After identifying the x coordinate, we need to move parallel to y direction and locate the y coordinate and finally we identify the z coordinate in the same way. In the last, we will join the points.

Answer:

Step-by-step explanation:

To find the total number of miles Karime walks, we need to multiply the number of miles she walks each day by the number of days:

3/4 mile/day * 5 days = 15/4 miles

We can simplify this fraction to be:

15/4 = 3 3/4

The whole number portion of this result is 3, and the fractional portion is 3/4. Therefore, the total number of miles Karime walks is between 3 and 4.

In other words, the two whole numbers between which the total number of miles Karime walks are 3 and 4.

Total number of miles Karime walks altogether is,

⇒ 5 miles

We have to given that,

Karime walks 3/4 of a mile each day for 5 days.

Hence, To find number of miles Karime walks altogether, we can multiply 3/4 by 5.

So, We get;

Total number of miles Karime walks altogether is,

⇒ 3/4 x 5

⇒ 15 / 4

⇒ 3.75

⇒ 4 miles

Because 3.75 is nearest to 4.

Answer: Spent $120 originally, profited by $36

Step-by-step explanation:

The total cost Stefan earned from selling the helmet and the bicycle is $139 + $17 = $156.

130% can be rewritten as [tex]\frac{130}{100}[/tex] which is simplified to 1.3.

Set up and this equation to find 130% of this price.

[tex]1.3x = 156\\x = 120[/tex]

Stefan spent $120 on these items.

Subtract this value from the selling price and solve.

[tex]156-120 = 36[/tex]

Stefan made $36 from selling the helmet and bicycle.

Step-by-step explanation:

3.14 is what percent of 15.70?

Use the percent-to-dollar conversion (100: 15.70) :

3.14 * 100% / 15.70 =

3.14 / 15.70 * 100% =

1/5 * 100% =

100% / 5 = 20% ==> percent tip

The ordered pairs that defines the solutions of the system of equations f(x) = x² - 2x + 3; f(x) = -2x + 7 are

(2, 3) and (-2, 11)

Ordered pairs refers to the arrangement of 2 numbers in the form (a, b)

As used in the cartesian coordinates

a refers to a point in the x direction b refers to a point in the y direction

Solutions of the system of equation is the points where the straight line intersect the curve or where the two graphs intersect.

the point of intersection

x² - 2x + 3 = -2x + 7

x² - 2x + 2x + 3 - 7 = 0

x² + 3 - 7 = 0

x² - 4 = 0

solving for x

x² = 4

x = √4

x = 2 OR -2

solving for y

For x = 2, y = -2 * 2 + 7 = 3

For x = -2, y = -2 * -2 + 7 = 11

hence we have the points to be (2, 3) and (-2, 11)

Answer:

I believe it is (C), the length of the golfers.

The things measured in the experiment are the bracelet and the length of the shots based off of it. The response variable is basically the dependent variable, and theyre trying to figure out if the lengths of shots are dependent on the bracelet.

Because of this, we know A and B are already wrong.

Now we're left with C and D.

If you think of graphing D as the y variable, it just doesn't make sense. Because how would you do that? But, if you made C the y variable, you can make a bar graph, which I think would make sense in this scenario.

Which is why I believe, the length of the shots is the response variable.

Nate's car was filled with 16 gallons of gas.

The concept is used in this is equations. An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. An equation is the set of variables, constants, and mathematical operations like addition, subtraction, multiplication, or division balanced by an equal sign. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc.

As gas is $2. 09 per gallon at the gas station.

$2. 09 → per gallon

and Nate filled up his car and spent $33. 44.

$33. 44 for fully filled → how many gallons ?

So,

33.44 / 2.09 = 16 gallons.

Therefore, Nate filled 16 gallons gas in his car.

Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. For example, the set of numbers x satisfying 0 ≤ x ≤ 5 is an interval that contains 0, 5, and all numbers between 0 and 5.
