Answer:

couch)14

chair)3

lamp)5

bed)6.25

table)10

Step-by-step explanation:

so, the whole question basically asks you to convert the units back and forth, (its very similar to the conversion of currency) & There are many ways to do this, ill show one of the methods, if u don't understand then i can show u another way....

ill do the first two-

COUCH-

1 inch: 0.5 ft

x inch:7ft  { x is the missing value ((model length of couch)) }

Now cross multiply

0.5x=7*1

x=7/0.5

x=14 inches

CHAIR-

1 inch: 0.5 ft

6 inch: x

Do the same step -Cross multiply

1x=0.5*6

x=3/1

x=3

The equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.

Two lines with slopes m₁ and m₂ are parallel when m₁ = m₂ and perpendicular when m₁*m₂ = -1.

In the question, we are asked for the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12.

The given line can be shown as:

x - 4y = 12,

or, - 4y = - x + 12,

or, y = x/4 - 12/4,

or, y = x/4 - 3.

Comparing it to the slope-intercept form of a line, y = mx + b, we get the slope, m = 1/4.

The line parallel to this will also have the slope, m = 1/4.

The required line passes through the point (8, -4).

Using the one-point formula, (y - y₁) = m(x - x₁), we can write the required equation as:

y - (-4) = (1/4)(x - 8),

or, y + 4 = x/4 - 2,

or, y = x/4 + 2,

or, x/4 - y = -2,

or, x - 4y = - 8.

Thus, the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.

Answer:

His songs were played 4 times in a commercial, and 3 times in a movie.

Step-by-step explanation:

Let x represent the number of times his songs were played in a commercial, and y represent the number of times his songs were played in a movie.

Since we know Owen's songs were played on 4 more commercials than in movies, we can write the expression

x = y + 4

Owen gets $50 every time one of his songs is played in a commercial and $140 every time one of his songs is played in a movie, so we can add these numbers into the equation below.

140y + 50x = $770

We can use the equation two lines above and substitute it into this equation so it now becomes:

140y + 50(y +4) = 770

Now we operate the equation so it becomes:

140y + 50y + 200 = 770

Now we reduce and add like terms.

190y = 770 - 200 = 570

190y = 570

570 / 190 = 3 (3 movies)

x = y + 4 = 7

y = 3

x = 3 + 4 = 7

So therefore Owen's songs were played 4 times in a commercial (x), and 3 times in a movie. (y)

Hope this helps.

Step-by-step explanation:

X° + 52° + 78° = 180°

X° + 130° = 180°

X° + 130° - 130° = 180° - 130 °

In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Hence, the length of u is 5.54 inches.

Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.

u² = s² + t² - 2(s)(t)·cos U

Given that the ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°.

We can find the length of u by using the Cosine rule

u² = s² + t² - 2(s)(t)·cos U

u² = 4.6² + 1.8² - 2(4.6)(1.8)·cos 118

u² = 19.78 + 3.24 - 16.56 x cos U

u² =  19.78 + 3.24 + 7.77

u² = 30.79

u = 5.54

Hence, the length of u is 5.54 inches.

The value of function f when x is (-3) is 9.

To solve the value of function for the value of x as -3, we will simply keep the value of x in the equation.

Rewriting the equation

f(x) = -x + 6

Keep the values of x in the above equation

f(x) = - (-3) + 6

Adding the two negative signs, hence, the value will be 3.

f(x) = 3 + 6

Performing addition to find the value of f(x) when value of x is (-3)

f(x) = 9

Therefore, the value of f(x) is 9.

Mid point of the length segment PQ has endpoints P(-3, 4) and

Q(1, 7) is (1,11/2).

Mid point = {(-3+1)/2, (4+7)/2}

Mid point = (1,11/2)

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the endpoints, and it is equally distant from both of them. It cuts the section in half.

A line is said to be a bisector when it divides another line into two identical segments. The line will be split at its midpoint by the bisector. A compass and straightedge can be used to determine the midpoint of a line segment. See creating a line segment's perpendicular bisector.

Answer:

Undefined

Step-by-step explanation:

The line is vertical and therefore has an undefined slope.

If a coffee machine dispenses 8-ounce cups of coffee automatically. and the amount of coffee may vary by 3% then the least and greatest number of ounces the coffee machine may dispense is 7.76 and 8.24 respectively.

The least and greatest number of ounces the coffee machine may dispense can be calculated by converting the percentage given.

As, 3% = 3 / 100

3% of 8 = 3 / 100 × 8 = 24 / 100 = 0.24

Now by adding and subtracting the calculated value to 8, the least and greatest number of ounces can be determined.

8 - 0.24 = 7.76

8 + 0.24 = 8.24

Hence, the least ounces the coffee machine may dispense is equal to 7.76 and the greatest number of ounces the coffee machine may dispense is calculated to be 8.24 ounces.
