1 quart 2 pints

1 pint 2 cups

1 cup = 8 fluid ounces

if 1 quart 2 pints, then 4 quarts will be

= 4 * 2 = 8 pints

if 1 pint 2 cups, then 8 pints will be

= 8 * 2 = 16 cups

if 1 gallon is 16 cups, the 2 gallons will be

= 16 * 2 = 32 cups

Question 2
Name the slope and one point that is on the line represented by the equation:
y+ 3 =
(x+7)
=-- and point (-7, -3)
m=
and point (7,3)
Om= and point (-7, -3)
and point (-7, -3)

Answers

The slope of the line is equal to 1 and a point lying on the line with the given equation is (7, 3).

The equation of the line is given as y + 3 = x + 7. First, we write the equation of the line in proper form. It can be written in slope-intercept form as y = mx + c where m is known as the slope of the line and c is the intercept made by the line.

Now, according to the equation given in question.

y = x + 7 - 3

y = x + 4

If we compare this equation with the slope-intercept form of line, we get the slope equal to one.

y = mx + c

y = x + 4

=> m = 1 and c = 4.

A point which satisfies the equation y = x + 4 can be (7, 3) as

7 = 3 + 4

=> 7 = 7 (L.H.S. = R.H.S.)

Thus, slope of the line is equal to 1 and a point lying on the line with the given equation is (7, 3).

The value of g (7) is 16.

What is Piecewise function?

A piecewise function is a function which built from pieces of different functions over different intervals.

The given function is;

g (x) = x² - 5             , x ∈ (-∞, -7)

      = 9x - 17            , x ∈ [-7, 2]

      = (x + 1) (x - 5)    , x ∈ (2, ∞)

Now, Find the value of g (7) as;

Since, Number 7 is belong in interval (2, ∞).

Hence, To find the value of g (7) we use the function,

g (x) = (x + 1) (x - 5)    , x ∈ (2, ∞)

Substitute x = 7 we get;

g (x) = (7 + 1) (7 - 5)

g (7) = 8 * 2

What is a conversion factor?

A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.

Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.

Conversion:

1 lbs = 0.0005 tons

1500 lbs = 0.75 tons

1200 lbs = 0.6 tons.

Now, we can determine the total amount of coal delivered in these two months:

Total amount of coal = 3 tons + 0.75 tons + 2 tons + 0.6 tons

Total amount of coal = 6.35 tons.

B)

C)

–3.5

D)

–1.13

Answers

Answer:

A) 3.5

Step-by-step explanation:

Solving the equation:  First bring all the terms with variable 't' to one side of the equation.          

                4.3t + 6.8 = 8.4t - 7.55

         Subtract 8.4t from both sides,

              4.3t - 8.4t +6.8 = -7.55

        Combine like terms,

                      -4.1t  + 6.8 = -7.55

Now isolate 't'

                  To isolate 't' first subtract 6.8 from both sides.

                   -4.1t  = -7.55 - 6.8

                   -4.1t  = -14.35

                Divide both sides by (-4.1)

                      t = -14.35 ÷ (-4.1)

simplify |8-40/4^3| 4^2 - 8 A.0 B.10 C.20 D.30

Answers

The required answer for the given expression is 0.

What is simplification?

Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube  roots, plus and minus.

Now the given expression is,

|8-40/4^3| 4^2 - 8

Solving the mod first,

Since 4^3 = 64 ; 4^2 = 16,

and 8 - 40 = -32

Therefore,

|8-40/4^3| 4^2 - 8 = |-32/64|16 - 8

Now solving

⇒ 32/64 = 1/2

Therefore we get,

|8-40/4^3| 4^2 - 8 = |-31/2| 16 - 8

Now since, |-a| = a

therefore, |-1/2| = 1/2

Therefore we get,

|8-40/4^3| 4^2 - 8 = (1/2) 16 - 8

Now, since (1/2) 16 = 8

Therefore we get

|8-40/4^3| 4^2 - 8 = 8 - 8

solving we get,

|8-40/4^3| 4^2 - 8 = 0

this is the required answer for the given expression.

Thus, the required answer for the given expression is 0.

The height of a box is 7 inches. The length is three inches more than the width. Find the width if the volume is 910.​

Answers

The width of the box whose height is given as 7 inches and length is three inches more than the width given a volume of 910 is; 10 inches.

What is the width of the box in discuss whose height, length and width are as described in the task content?

It follows from the task content that the height of the box is; 7 inches.

Let, x = width of the box and;

x+ 3 = length of the box.

Therefore, since the volume of a box is given by the formula;

V = l × b × h

Therefore, we have;

910 = 7 (x) (x+3)

Divide both sides by; 7

130 = x² + 3x

x² + 3x -130 = 0.

(x+13) (x-10) = 0

Therefore, x = -13 or x = 10.

Ultimately, the possible values of the width are; -13 or 10.

Since the width cannot be a negative number, it follows that the width of the box in discuss is; 10 inches.

A bicyclist brakes from 21 m/s to stop in 32.3 m. what is the acceleration of the bicyclist

Answers

The acceleration of the bicyclist is 6.83 m/s².

The given parameters;

Initial velocity of the bicycle (u) = 21 m/s

Distance travel by the bicycle (s) = 32.3 m

We have to find the acceleration of the bicyclist.

How to calculate the acceleration?

If the initial velocity is u, final velocity is v and distance travel by object is s then we can calculate acceleration as;

v² = u² + 2as

Initial velocity of the bicycle (u) = 21 m/s

Distance travel by the bicycle (s) = 32.3 m

Final velocity of the bicycle (v) = 0

Hence, The acceleration of the bicycle is calculated as follows;

v² = u² + 2as

Where, v is the final velocity of the bicycle.

0 = u² + 2as

2as = - u²

a =  - u²/2s

a = - (21)²/2*32.3

a = - (21)²/64.6

a = -441/64.6

a = -6.83

The subtraction of the expression 10√27 - 4√12 is 22√3.

Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together.

In mathematics, subtraction involves removing anything from a group or a number of objects. What is left in the group gets smaller when you subtract.

Consider the expression,

y = 3√20x + 8√45x - 4√5x

Now, the number in the root can also be written as:

20 = 2 × 2 × 5

45 = 5 × 3 × 3

Therefore,

y = 3√20x + 8√45x - 4√5x

y = 3( √[2 × 2 × 5] )x + 8( √[5 × 3 × 3] )x - 4√5x

y = 3 × 2√5x + 8 × 3√5x - 4√5x

Answers

Using sine formula, the seat on a Ferris wheel is 50√3 feet closer to the ground after rotating 60°.

One of the 6 trigonometric functions is the sine function. Sine function can be described as the ratio of the length of the opposite side of the triangle to its hypotenuse.

sin x = (opposite side) / (hypotenuse)

where "opposite side" is the length of the side opposite to angle x

If the wheel rotates 60°, causing the height of the seat to decrease, using sin formula, solve for the vertical distance between the positions before and after the rotation.

sin x° = (opposite side) / (hypotenuse)

where x = 60

opposite side = vertical distance between the positions before and after the rotation

hypotenuse = radius = 200 feet/2 = 100 feet

sin 60° = opposite side / 100 feet
