How to use a generic rectangle by multiplying 54×32

Answer:

[tex]\text{The equation of line is }x=-4[/tex]      

Step-by-step explanation:

Given that line is passing through the point (-4, 0) and parallel to the y-axis.

we have to find the equation of the line.

[tex]\text{As the slope of y-axis is }\infty\text{ i.e }\frac{1}{0}[/tex]

Since the slope of parallel lines are equal therefore we have to find the equation of line with slope infinity and passing through the point (-4, 0).

The equation of line pass through the point (x',y') with slope m is

[tex]y-y'=m(x-x')[/tex]

The equation of line with slope infinity and passing through the point (-4, 0) is

[tex]y-0=\frac{1}{0}(x-(-4))[/tex]

[tex]x+4=0[/tex]

[tex]x=-4[/tex]

which is required equation.

Hence, option 1 is correct.

Replace x and Y in the answers and see which one works:

A) 4(4) -3 = 16-3 = 13, not -3 FALSE.

B) 1/2(4) - 5 = 2-5 = -3 TRUE

The correct answer is B

From a 16 foot board, 4 full pieces each 3 1/4 feet long can be cut. Moreover, 16.0 inches, a common spacing for vertical studs, is equivalent to 40.64 centimeters.

To determine how many lengths of 3 1/4 feet can be cut from a 16 foot board, we need to divide the total length of the board by the length of each desired piece. First, we convert the mixed number 3 1/4 to an improper fraction, 13/4. Then, we perform the division: 16 feet divided by 13/4 feet.

This calculation can be set up as follows:

(16 feet) \/ (13/4 feet) = (16 feet) × (4/13) = (64/13) feet = 4 remainder 12/13

Therefore, you can cut 4 full pieces that are 3 1/4 feet long from a 16 foot board, with a remainder of 12/13 of a foot.

If we want to convert the placement of vertical studs, which are typically 16 inches apart, to centimeters, we use the conversion factor that 1 inch equals 2.54 centimeters. 16.0 inches multiplied by 2.54 equals 40.64 centimeters.

Leila's gross earnings are calculated by adding her base pay of $290 to her commission of $13.80, which is 3% of her sales over $500. For the week, her total gross earnings are $303.80.

The question involves calculating Leila's gross earnings for a week where she sold $960 worth of merchandise while working at Famous Footwear. To find her earnings, we need to calculate her base pay plus the commission on sales over $500.

Leila's base pay is $290 per week. Since she sold $960, the amount over $500 that is eligible for commission is $960 - $500 = $460. Her commission is 3% of this amount, which is 0.03 * $460 = $13.80.

Therefore, Leila's total gross earnings for the week are her base pay plus her commission: $290 + $13.80 = $303.80.

we are given two system of equations

First equation is

[tex]y=2x-1[/tex]

we can write as

[tex]-2x+y=-1[/tex]

Second equation is

[tex]6x-y=13[/tex]

now, we can find augmented matrix

[tex]A=\begin{pmatrix}-2&1&-1\\ 6&-1&13\end{pmatrix}[/tex]

now, we can change it into reduced row echelon form

step-1: multiply the 1st row by -1/2

[tex]A=\begin{pmatrix}-1&-1/2&1/2\\ 6&-1&13\end{pmatrix}[/tex]

step-2: add -6 times the 1st row to the 2nd row

[tex]A=\begin{pmatrix}-1&-1/2&1/2\\ 0&2&10\end{pmatrix}[/tex]

step-3:multiply the 2nd row by 1/2

[tex]A=\begin{pmatrix}-1&-1/2&1/2\\ 0&1&5\end{pmatrix}[/tex]

step-4:add 1/2 times the 2nd row to the 1st row

[tex]A=\begin{pmatrix}1&0&3\\ 0&1&5\end{pmatrix}[/tex]

so, we will get

[tex]x=3,y=5[/tex]

Given : AB = 44 + 3x

BC = 33 + x

CD = 64 − x

AD = 48 − 2x.

Opposite sides are AB and CD.

BC and AD.

Setting AB equals CD

We get

44 + 3x = 64 − x

Adding x on both sides, we get

44 + 3x+x = 64 − x+x

44 +4x = 64.

Subtracting 44 from both sides, we get

44-44 +4x = 64 - 44.

4x =20

Dividing both sides by 4, we get

x= 5.

Let us plug x=5 to find the length of each side, we get

AB = 44 + 3x = 44 +3(5) = 44 + 15 = 59 cm

BC = 33 + x = 33 + 5 = 38 cm

CD = 64 − x = 64 - 5 = 59 cm

AD = 48 − 2x = 48 - 2(5) = 48 - 10 = 38 cm.

You put x from your question its going to be multiply by the fraction.

And it gave us ⇒ [tex]11\frac{1}{6}* 4 \frac{2}{7}[/tex]

First you had to convert by the mixed numbers into improper fractions.

And it gave us ⇒ [tex]=\frac{67}{6}*4\frac{2}{7}[/tex]

Then you convert by the mixed numbers again into improper fractions.

And it gave us ⇒ [tex]\frac{67}{6}* \frac{30}{7}[/tex]

You can also cross it out by the common factor of 6.

And it gave ⇒ [tex]\frac{67}{1}*\frac{5}{7}[/tex]

Next you had to multiply by the fraction.

And it gave us ⇒ [tex]\frac{67*5}{1*7}[/tex]

And then multiply the numbers.

[tex]67*5=335[/tex]

And it gave us ⇒ [tex]\frac{335}{1*7}[/tex]

You can also multiply the numbers again.

[tex]7*1=7[/tex]

And it gave us ⇒ [tex]\frac{335}{7}[/tex]

Finally you had to convert into the improper fraction to mixed their numbers.

[tex]\frac{335}{7}=47 \frac{6}{7}[/tex]

Final answer ⇒ 47 6/7

Answer:

1/4 = 3/12 and 1/6 = 2/12

Step-by-step explanation:

We are given two fractions with denominator 4 and 6.

To find the least common denominator, of 4 and 6.

Factorise 4 and 6.

4 = 2x2

6=2x3

Hence Least common denominator = 2x2x3 =12

Make the given fractions to equivalent fractions with common denominator 12.

1/4 = 1(3)/4(3) = 3/12 and

1/6 = 1(2)/6(2)= 2/12

Hence answer would be

3/12 and 2/12

To rewrite the fractions 1/4 and 5/6 with a least common denominator, find the least common multiple (LCM) of the denominators, which is 12. Multiply the numerators and denominators of each fraction by the appropriate factor to obtain the rewritten fractions.

To rewrite the fractions 1/4 and 5/6 with a least common denominator, we need to find the least common multiple (LCM) of the denominators, which in this case are 4 and 6.

To find the LCM, we can list the multiples of each denominator until we find a common multiple. For 4, the multiples are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ... And for 6, the multiples are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, ... The first common multiple we find is 12, so that is the least common denominator (LCD).

To rewrite 1/4 with the LCD of 12, we need to multiply both the numerator and the denominator by 3: (1 * 3) / (4 * 3) = 3/12.

To rewrite 5/6 with the LCD of 12, we need to multiply both the numerator and the denominator by 2: (5 * 2) / (6 * 2) = 10/12.

If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

PQ → (0, 3), (2, 0).

Substitute:

[tex]m=\dfrac{0-3}{2-0}=\dfrac{-3}{2}=-1.5[/tex]

QR → (2, 0), (4, -3).

Substitute:

[tex]m=\dfrac{-3-0}{4-2}=\dfrac{-3}{2}=-1.5[/tex]

Step-by-step explanation:

Answer:

Displacement versus time is velocity

Step-by-step explanation:

Displacement versus time is velocity

Acceleration is change in velocity over time

Speed is distance over time

Momentum is mass times velocity

The slope of a graph in physics can represent several different concepts, depending on the graph. On a distance-time graph, the slope stands for speed or velocity. Meanwhile, on a velocity-time graph, the slope signifies acceleration. Momentum is generally not represented by the slope.

In physics, the slope of a graph can indeed represent several concepts, but only when plotted correctly. These concepts include speed, velocity, acceleration, and momentum. However, when we're talking about a distance-time graph, the slope typically represents speed or velocity, depending on whether the direction of movement is accounted for or not. An increasing slope on such a graph indicates objects are moving at a faster speed or velocity over time.

On the other hand, in a velocity-time graph, the slope represents acceleration. Positive acceleration causes the velocity of an object to increase, while negative acceleration, or deceleration, slows it down. Similarly, if there is no change in the slope, it means the object is moving at a constant velocity.

Momentum, in general, is not represented by the slope of a graph but rather is the product of an object's mass and its velocity.

The correct answer is option D, the approximate population density of the bacteria in the dish is 4,246 bacteria / square inch

Step-by-step explanation:

They give us the diameter of the plate, then the first step is to calculate their area.

The area of a circle according to the diameter is:

[tex]A = \frac{\pi}{4}(d) ^ 2[/tex]

Where d is the diameter.

So:

[tex]A = \frac{\pi}{4}36\\ A = 9\pi\\ A = 28.274.inches ^ 2[/tex]

7 people have averaged fewer than 4,000 steps.

Option A is the correct answer.

Given,

The bar graph of the number of steps on the horizontal line and the number of people on the vertical line.

We need to find how many people averaged fewer than 4,000 steps each day.

Read the bar graph.

Steps - 0 - 1,999

= 2 people

Steps - 2,000 - 3,999

= 5 people

Steps - 4,000 - 5,999

= 12 people

Steps - 6,000 - 7,999

= 7 people

Steps - 8,000 - 9,999

= 3 people

Find the number of people who have fewer than 4,000 steps.

We have,

Steps - 0 - 1,999

= 2 people

Steps - 2,000 - 3,999

= 5 people

So,

2 + 5 = 7

= 7 people

Thus 7 people have averaged fewer than 4,000 steps.

Answer: Two consecutive square numbers be 16 and 9.

Step-by-step explanation:

Let first consecutive square number be x²

Let second consecutive square number be (x+1)²

According to question,

[tex]x^2\times (x+1)^2=144[/tex]

Now we'll do this by factorisation,

[tex]144=2\times2\times2\times2\times3\times3\\\\144=16\times 9[/tex]

So, two consecutive square numbers are 16 and 9

Consecutive numbers are numbers that follow one another.

The consecutive squares are: 9 and 16

Let the bigger square be x^2

So, we have:

[tex]\mathbf{(x - 1)^2 \times x^2 = 144}[/tex]

Express 144 as 12^2

[tex]\mathbf{(x - 1)^2 \times x^2 = 12^2}[/tex]

Take square roots of both sides

[tex]\mathbf{(x - 1)\times x = 12}[/tex]

Expand

[tex]\mathbf{x^2 - x = 12}[/tex]

Rewrite as:

[tex]\mathbf{x^2 - x - 12 = 0}[/tex]

Expand

[tex]\mathbf{x^2 - 4x +3x- 12 = 0}[/tex]

Factorize

[tex]\mathbf{x(x - 4) +3(x- 4) = 0}[/tex]

Factor out x - 4

[tex]\mathbf{(x +3) (x- 4) = 0}[/tex]

Solve for x

x= -3 or x = 4

x cannot be negative.

So: x = 4

Square both sides

[tex]\mathbf{x^2 = 4^2}[/tex]

[tex]\mathbf{x^2 = 16}[/tex]

Calculate the smaller square

[tex]\mathbf{(x - 1)^2 = (4-1)^2}[/tex]

[tex]\mathbf{(x - 1)^2 = 9}[/tex]

Hence, the consecutive squares are: 9 and 16

The ball hits the ground at unknown time (t) when the height (h) = 0

h(t) = -16t² + vt + h    ⇒ v = 64, h = 0, h(t) = 0, find t

 0  = -16t² + 64t

 0  = -16t(t - 4)

0 = -16t       or    0 = t - 4

  t = 0         or        t = 4

It starts at t = 0 seconds and ends at t = 4 seconds

Answer: B

Final answer:

Using the kinematic equation for vertical motion, we find that the golf ball will hit the ground after 4 seconds. We factor the kinematic equation to solve for the time given initial velocity and gravity's acceleration, ignoring the 0 time solution. TΔherefore, the correct option is b.

Explanation:

The question asks after how many seconds a golf ball hit from ground level with an initial vertical velocity of 64 ft/s will hit the ground. This problem involves kinematic equations of motion under the influence of gravity. We can use the equation for vertical motion: distance = initial velocity × time + 0.5 × acceleration × time². Since the ball returns to ground level, the distance covered is 0. Taking downward as positive, gravity's acceleration is +32 ft/s² (the usual acceleration due to gravity in units of ft/s²). We can rearrange the equation to solve for time (t): 0 = 64t + 0.5 × 32t². Factoring out t gives us t(64 + 16t) = 0, and solving for t gives us t = 0 or t = -64/16 = -4 seconds. Since time cannot be negative in this context, the positive solution reflects the time after launch, thus the answer is 4 seconds, which is option b.
