The price of Stock A at 9 A.M. was ​$13.64. Since​ then, the price has been increasing at the rate of ​$0.06 each hour. At noon the price of Stock B was ​$14.39. It begins to decrease at the rate of ​$0.11 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Answers

Answer 1

Answer: In about 3 hours and 21 minutes the prices of the two stocks will be the same at $14.02

Step-by-step explanation: We can begin by calculating the value of stock A at noon by adding $.06 per hour or 3 hours, $0.18 to its 9am price. $13.64 + 0.18 = 13.82

Then set up the equation to find the point where the prices are equal:

x is the amount of time in hours.

.06x + 13.82 = -.11x + 14.39    

Add .11x to both sides and subtract 13.82 from both sides

.06x + .11x = 14.39 - 13.82

.17x = 0.57

x = 3.353 hours

To get minutes instead of a decimal, multiply .353 × 60 ≈ 21 minutes

The time is 3:21

The increase in price is for stock A is about $0.20

13.82 + .0.06(3.353) = $14.02

Stock B decreased by $0.37

14.39 - 0.11(3.353) = $14.02

Answer:

\(\huge\boxed{\sf x =28 \textdegree}\)

Step-by-step explanation:

Given that,

∠IAK = 62°

∠IAK + ∠IAD = 90° (Complementary angles)

62 + ∠IAD = 90°

Subtract 62 to both sides

∠IAD = 90 - 62

∠IAD = 28°

∠IAD = ∠ACB (Corresponding angles are equal)

So,

∠ACB = 28°

∠ACB = ∠GCJ (Vertically opposite angles are equal)

So,

28° = x°

OR

x° = 28°

\(\rule[225]{225}{2}\)

Answer:

28 degrees

Step-by-step explanation:

If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.

--> Angle LAJ is 62 degrees

If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.

We know that in a triangle, there are three angles, and the angle measures combined equals 180.

Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.

--> 180 - 90 - 62 = 28

--> Angle BCA = 28 degrees

Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.

Angle x = 28 degrees

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart

Answers

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

This is an example of discrete data

Answers

The contractor is in charge of having people so it’s a contractor or 1 26/

This is about understanding domain of a function.

The domain of the function is x is a set of positive integers.  

We are given the function;

f(x) = 126/x

Where;

f(x) is the number of days it would take to complete a project with x number of workers

x is number of workers it will take to complete the project.

We want to find the domain for the given function.

Domain is defined as the set of all possible input values for which the function is defined.

Let's try x = 0 workers.

f(x) = 126/0 ; this is undefined and so x cannot be zero.

Let's try x = 1 worker

f(x) = 126/1 = 126 days

Let's try x = 10 workers

f(x) = 126/10 = 12.6 days

Let's try x = 100 workers

f(x) = 126/100 = 1.26 days

We see that every positive integer is a possible value of x that can make the function defined. Since 0 and negative numbers will make the function invalid.

Thus, the domain of the function is x is a set of all positive integers.

To find the multiplication expression equivalent to 6/8 divided by 2/3, you can use the reciprocal (or multiplicative inverse) of the divisor and then multiply:

6/8 divided by 2/3 can be rewritten as:

(6/8) x (3/2)

To simplify, you can reduce 6/8 to 3/4:

(3/4) x (3/2) = 9/8

So the multiplication expression equivalent to 6/8 divided by 2/3 is 9/8.

To confirm this, you can also simplify the expression 6/8 divided by 2/3 using the division rule of fractions:

6/8 divided by 2/3 is the same as multiplying 6/8 by the reciprocal of 2/3:

(6/8) x (3/2)

Then, you can simplify the expression by reducing the fraction 6/8 to its simplest form:

(3/4) x (3/2)

Finally, you can multiply the two fractions together to get:

(3 x 3)/(4 x 2) = 9/8

Therefore, the multiplication expression equivalent to 6/8 divided by 2/3 is 9/8.
