What is COEFFICIENT of 12c

Product is multiplication.

Since the answer needs to be greater than 2 either the fraction needs to be an improper fraction ( meaning the fraction would be greater than 1) or the whole number would need to be greater than 2.

One answer would be 5 x 2/3 = 3 1/3

Answer:

So, total gallons were made in all =9.31 gallons

Step-by-step explanation:

We are given

A scientist repeated an experiment three times, making 1.42, 3.81, and 4.08 gallons of a new product

so,

first experiment =1.42 gallons

Second experiment =3.81 gallons

Third experiment =4.08 gallons

now, we can find total gallons

total gallons = first experiment + second experiment + third experiment

total gallons =1.42 gallons + 3.81 gallons +4.08 gallons

total gallons =9.31 gallons

Answer:

42 digits right of the decimal point.

Step-by-step explanation:

Trailing zeroes are those which we get in decimal representation and after that there comes no digit.

We have been given the expression:

[tex]0.4^{24}\cdot 0.375^{22}[/tex]

We will simplify it to get the result that is the right of the decimal point.

[tex]1.19709242282867431640625\cdot 10^{-19}[/tex]

When we will operate [tex]10^{-19}[/tex] that means decimal point will be shifted 19 digits left of its present position.

Hence, we get:

[tex].000000000000000000119709242282867431640625[/tex]

Hence, 42 digits right of the decimal point.

Step-by-step explanation:

The intersection is made when the red and blue line meet. If you make a mark down that looks like 1.5 and if you go up to your y axis the coordinate is 3/4 around the one since it is not over the one.

A. (1.5, 0.75)  coordinate pair is the best estimate of the point of intersection in this graph.

An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.

Pair in Order = (x, y)

x is the abscissa, the distance measure of a point from the primary axis x

y is the ordinate, the distance measure of a point from the secondary axis y

By observing the graph the intersection of the two lines is (1.5, 0.75).

As, It lies somewhat in the middle of x = 1 and x = 2, And for y it is more than 0.5 but less than 1 so it must be (1.5, 0.75).

Answer:

8/25

Step-by-step explanation:

Steps:

1. First you count how many number are divisible by three. The numbers are 3, 6, 9, 12, 15, 18, 21, and 24, which is a total count of 8 numbers.

2. Then you count the numbers of slips of paper, which you know is 25.

3. Finally, put the number of numbers that are divisible by three or the total slips of paper to find your answer.

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)

When lines are parallel, their slopes have to be the SAME.

Since the given line's slope is -1/2, the parallel line's slope is also -1/2

y = -1/2x + b

To find "b", plug in the point (2, -2) into the equation

y = -1/2x + b

-2 = -1/2(2) + b

-2 = -1 + b     Add 1 on both sides

-1 = b

y = -1/2x - 1

Answer:

x = 17.5 and y = 35

Step-by-step explanation:

2x + 10 = y + 10 ( alternate angles )

subtract 10 from both sides

2x = y ⇒ 6x = 3y → (1)

the sum of the 3 angles in the triangle = 180°

6x + y + 10 + 30 = 180 ( replace 6x by 3y )

3y + y + 40 = 180

4y + 40 = 180 ( subtract 40 from both sides )

4y = 140 ( divide both sides by 4 )

y = 35

substitute y = 35 into (1)

2x = 35 ( divide both sides by 2 )

x = 17.5

Answer:

They will meet at 3836 meters

Step-by-step explanation:

Maya is at 7832 meters

Juan is at -160 meters  ( below sea level)

If they are meeting at the midpoint, we add them together and divide by 2

Midpoint = (7832 + -160)/2

               = (7672)/2

               =3836 m

Answer:

The midpoint elevation will be 3,836 meters.

Step-by-step explanation:

Maya's elevation of 7832 can be represented by the positive integer +7832 since she is above sea level.  Sea level would represent 0 on our number line.  However, Juan is below sea level, so we can represent his distance at -160.  When we add these two integers together +7832 + (-160) = 7672 meters above sea level.  Since Maya and Juan are going to meet at the midpoint, we would divide our overall distance (7672) by two to get 3836 meters.  

The caloric content of the pan pizza is 1110 calories and the caloric content of the beef burrito is 1230 calories.

Let's assign variables to the caloric content of the items. Let x represent the caloric content of the pan pizza and y represent the caloric content of the beef burrito. We can form two equations based on the given information:

x + 2y = 3570

2x + y = 3450

To solve this system of equations, we can use either substitution or elimination method. Let's use substitution method:

y = 3450 - 2x

x + 2(3450 - 2x) = 3570

x + 6900 - 4x = 3570

-3x = -3330

x = 1110

2(1110) + y = 3450

2220 + y = 3450

y = 1230

Therefore, the caloric content of the pan pizza is 1110 calories and the caloric content of the beef burrito is 1230 calories.

Answer:

407.22 foot is the boat from the base of the lighthouse

Step-by-step explanation:

Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.

Let x foot be the distance of the object(boat) from the base of the lighthouse

Angle of depression = [tex]7^{\circ}[/tex]

[tex]\angle CAB = \angle DCA = 7^{\circ}[/tex]       [Alternate angle]

In triangle CAB:

To find AB = x foot.

Using tangent ratio:

[tex]\tan (\theta) = \frac{Opposite side}{Adjacent Base}[/tex]

[tex]\tan (\angle CAB) = \frac{BC}{AB}[/tex]

Here, BC = 50 foot and [tex]\angle CAB =7^{\circ}[/tex]

then;

[tex]\tan (7^{\circ}) = \frac{50}{x}[/tex]

or

[tex]x = \frac{50}{\tan 7^{\circ}}[/tex]

[tex]x = \frac{50}{0.1227845609}[/tex]

Simplify:

AB = x = 407.217321 foot

Therefore, the boat from the base of the light house is, 407.22'

Using the tangent of the angle of depression, the distance from the boat to the base of the lighthouse is calculated to be approximately 407 feet.

To solve this problem, we need to use trigonometry. The angle of depression from the observer at the top of the lighthouse to the boat is the same as the angle of elevation from the boat to the observer because these angles are alternate interior angles formed by parallel lines (the water's surface and the height level at the observer's eyes) and a transversal (the line of sight from the observer to the boat).

We have a right triangle where the lighthouse height is the opposite side to the angle of elevation, and the distance from the boat to the lighthouse is the adjacent side. Using the tangent function, which relates the opposite side to the adjacent side in a right angle triangle, we can set up the following equation:

tangent(7°) = opposite/adjacent or tan(7°) = 50/adjacent

So the adjacent side, which is the distance to the boat, is:

adjacent = 50 / tan(7°)

Using a calculator we find:

adjacent ≈ 50 / 0.1228 ≈ 407.2 feet

Thus, to the nearest foot, the boat is approximately 407 feet away from the base of the lighthouse.

Answer:

As a number, there is no "number" for the slope of the vertical line (N/A)

Step-by-step explanation:

Remember that slope is the "y" measurements. If there is " ' infinite ' " y's, then there is no exact slope measurement, which makes it N/A

~

The slope of a vertical line is undefined because it does not have a definitive rise over run, as the change in x is zero, leading to division by zero. Graphically, slopes indicate the steepness of a line, with positive slopes inclining upward, negative slopes declining downward, and the slope of a horizontal line being zero. Vertical lines have an infinite slope, which is another way of saying they have no defined steepness in the typical sense.

The slope of a vertical line is a concept that often confuses students, primarily because a vertical line does not have a slope in the way we usually understand it. The slope value of a line typically tells us how much the y-value goes up or down for a unit change along the x-axis. For a horizontal line, the slope equals zero, but a vertical line is different. Since the x-value does not change as the y-value increases or decreases, you would be dividing by zero, which is mathematically undefined. Thus, the slope of a vertical line is undefined.

Graphically, if the slope of a line increases, it becomes steeper, and conversely, if it decreases, the line becomes flatter. A positive slope means that as you move to the right along the x-axis, the line goes up. On the other hand, a negative slope indicates that the line goes down as you move right. However, these concepts do not apply to vertical lines, as they do not have a slope that could be described as positive or negative. Instead, their infinite slope is a way of expressing that they are not functionally graded.

Final answer:

Tonya ran the race approximately 6.13 seconds faster than Jada.

Explanation:

To find out how much faster Tonya ran the race, we need to calculate the difference between their race times.

Tonya's race time is 69.07 seconds, while Jada's race time is 75.2 seconds.

To calculate the difference, we subtract Jada's race time from Tonya's race time: 69.07 - 75.2 = -6.13 seconds.

Therefore, Tonya ran the race approximately 6.13 seconds faster than Jada.

Final answer:

Jim can rent the car for a maximum of 4 whole days with his budget of $115, as the inequality 21d + 0.10(250) <= 115 reveals that he doesn't have enough funds to cover the fifth day.

Explanation:

To determine the maximum number of days Jim can rent a car, we can set up an inequality. The cost per day to rent the car is $21.00, and he will be charged $0.10 for every mile he drives. Jim will travel 250 miles in total. Jim has a budget of $115.00 to spend.

Let d represent the number of days Jim can rent the car for. The inequality would be:

21d + 0.10(250) ≤ 115

To solve for d, you would perform the following steps:

Solving the inequality:

21d ≤ 90

d ≤ 90 / 21

d ≤ 4.2857

Since Jim can only rent the car for a whole number of days, the maximum number of days he can rent the car is 4 days.

Therefore, Jim's belief that he can rent the car for a maximum of 5 whole days is incorrect because he does not have sufficient funds for the fifth day.

The range is the output, which would be the Y value.

The Y value would be calculated based on the input value for x.

any positive number raised to any value of x would be a positive number so 0.5^x would always be positive.

That would be multiplied by 4, which is a positive value, so the output ( Y value) would always be positive.

The range for this would be (0,∞)

The range of the function f(x) = 4 · 0.5^x is (0, 4], meaning it includes all numbers greater than 0 up to and including 4.

The value of 0.5^x decreases toward zero but never actually reaches it. Because the base is positive, the function will never produce negative values, so the smallest value f(x) can approach is 0. The coefficient 4 simply scales the output, so the function values will range from 0 to some maximum value, which occurs at x = 0. At x = 0, f(x) is at its maximum value, 4 · 1 = 4. Therefore, the range of the function is (0, 4], where 4 is included and 0 is excluded since the function can get arbitrarily close to 0 but never equal it.

Answer:

Step-by-step explanation:

Let the answer be represented by xy  where x is the tens digit and y is the ones digit.

The ones digit of a two-digit number is 4 more than the tens digit.

y = x+4

the sum of that number and the number reversed is 110

xy+yx = 110

Lets rewrite this vertically

 x y

 y x

1 1 0

We can replace y with x + 4  I will put the 4's in a separate row up top for ease of writing

 4 4

 x x

 x x

------

1 1 0

Taking the one's column, we get

2x +4 = 0  and I will assume there is a carry of 10

so rewriting

2x+4 = 10

Subtract 4 from each side

2x+4 -4 = 10-4

2x =6

Divide each side by 2

2x/2 = 6/2

x=3

We still need to find y

y = x+4

Substituting in x

y = 3+7

The speed of the first car was 6 miles/hour

Acceleration is rate of change of velocity.

[tex]\large {\boxed {a = \frac{v - u}{t} } }[/tex]

[tex]\large {\boxed {d = \frac{v + u}{2}~t } }[/tex]

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem!

Given:

Distance between two cars = d = 10 miles

Time Taken = t = 1 hour

Distance covered by the first car = d₁ = 2 + d₂

Unknown:

Speed of the first car = v₁ = ?

Solution:

[tex]d = d_1 + d_2[/tex]

[tex]10 = ( 2 + d_2 ) + d_2[/tex]

[tex]10 = 2 + 2d_2[/tex]

[tex]10 - 2 = 2 d_2[/tex]

[tex]8 = 2 d_2[/tex]

[tex]d_2 = 8 \div 2[/tex]

[tex]d_2 = 4 \texttt{ miles}[/tex]

[tex]\texttt{ }[/tex]

[tex]d_1 = 2 + d_2 = 2 + 4 = 6 \texttt{ miles}[/tex]

[tex]v_1 = d_1 \div t = 6 \div 1 = 6 \texttt{ miles/hour}[/tex]

Given:

The distance between the two cars is [tex]10{\text{ miles}}.[/tex]

The first car covered 2 miles more than the second car.

Explanation:

Consider the speed of the second car be “[tex]x[/tex]”.

Consider the speed of the first car be “[tex]x+2[/tex]”.

The distance covered by the first car in one hour is [tex]x + 2{\text{ miles}}.[/tex]

The distance covered by the second car in one hour is [tex]x{\text{ miles}}.[/tex]

The total distance covered by two cars is [tex]10{\text{ miles}}.[/tex]

[tex]\begin{aligned}x + 2 + x &= 10\\2x + 2 &= 10\\2x &= 10 - 2\\2x &= 8\\x&= 4\\\end{aligned}[/tex]

The speed of the second car is [tex]4{\text{ miles/h}}.[/tex]

The speed of the first car can be obtained as follows,

[tex]\begin{aligned}{\text{Speed}} &= x + 2\\&= 4 + 2\\&= 6{\text{ miles/h}}\\\end{aligned}[/tex]

The speed of the first car is [tex]\boxed{6{\text{ mph}}}[/tex] and the speed of the second car is [tex]\boxed{4{\text{ mph}}}.[/tex]
