Answer:

520 words

Step-by-step explanation:

Do 130 words divided by 5 minutes to get 26 words per minute.

Then you do 26 times 20 to get the answer of 520

hope this helps!!

Answer:

520 words.

Step-by-step explanation:

We can multiply the 5 minutes by 4 to find 20, so also multiply 130 by 4, which would result in 520.

Answer:

[tex]-1/13\text{ tub per hour}[/tex]

Step-by-step explanation:

First, let's find how much of the tub was used within the time.

We know that the tub was 2/3 full was Jenna started.

And it was only 1/6 full when Jenna ended.

Therefore, to find the amount used, we can subtract 1/6 from 2/3. So:

[tex]u=\frac{2}{3}-\frac{1}{6}[/tex]

Make a common denominator. Change 2/3 to 4/6 by multiplying both layers by 2. So:

[tex]u=\frac{4}{6}-\frac{1}{6}[/tex]

Subtract and reduce:

[tex]u=\frac{3}{6}=\frac{1}{2}[/tex]

Therefore, 1/2 of the tub was used after 6 1/2 hours.

To find the average hourly change, we will put the amount used over the amount of hours. 6 and 1/2 hours is the same as 13/2 hours. Therefore, the hourly change will be:

[tex]c=\frac{\frac{1}{2}}{\frac{13}{2}}[/tex]

Remember when dividing fractions, we:

1) Flip the divisor (the second number).

2) Change the division sign to a multiplication sign.

3) Multiply.

So:

[tex]c=\frac{1}{2}\div\frac{13}{2}\\\Rightarrow c=\frac{1}{2}\times \frac{2}{13}[/tex]

Multiply straight across and reduce:

[tex]c=\frac{2}{26}=\frac{1}{13}[/tex]

However, since we are using up the tub, our rate will be negative. Therefore:

[tex]c=-\frac{1}{13}[/tex]

Therefore, the average hourly rate was -1/13 tub per hour.

This means that after each hour, 1/13 of the tub will be used up.

Edit: Corrected Wrong Answer

Answer: -1/13 of a tub per hour

Step 1: Subtract.

2/3 - 1/6 = ?

Step 2: Find the common denominator.

4/6 - 1/6 = 3/6.

Step 3: Simplify the fraction.

3/6 = 1/2

Step 4: Put 1/2 over 13/2.

1/2 over 13/2

Step 5: Flip divisor around. Then divide.

1/2 ÷ 13/2

Step 6: Multiply.

1/2 × 2/13 = 2/26.

2/26 reduced = 1/13.

Since it was used, now it is -1/13

Answer = -1/13 of a tub per hour

Answer:

y=130

Step-by-step explanation:

1) combine all like terms for the inside angles of the triangle

2) because the sum of all angles = 180 add that to the sum of all like terms

3) now you replace the x's with 23

4) now we know that (3x-19)=50

5) take 180 and subtract 50

6) 180-50=130

Answer:

30

Step-by-step explanation:

20 divided by 12 is 5/3.

18x5/3 is 30, meaning the missing side is 30.

The value of x from the diagram is 30

These are shapes with the same sides and angles

From the given figures, we are to get the value of x as shown.

Using the similarity theorem;

Cross multiply

12x = 18 * 20

12x = 360

x = 30

Hence the value of x from the diagram is 30

Answer: 3.765

Step-by-step explanation:

Let's find out by replacing d with -12. Then we'll simplify the left side

|d+9| = 3

|-12+9| = 3 .... replace d with -12

|-3| = 3

3 = 3

Since we get a true statement, ie the same thing on both sides, this means the original equation is true when d = -12.

Therefore d = -12 is one of the two solutions to the original equation.

Answer:

True

Step-by-step explanation:

We can check this by substituting x = - 12 into the left side of the equation. If the result is equal to the right side then it is a solution.

| - 12 + 9 | = | - 3 | = 3 = right side

Thus x = - 12 is one of the solutions to the equation.

[ The other solution is x = - 6 ]

Area of triangle = 1/2 x base x height.

Area = 1/2 x 16 x 1/8

Area = 8 x 1/8

Area = 1 square inch

The area of the triangle calculated using the area formula is 1 in²

Given the Parameters :

Area of a triangle can be obtained using the relation :

Substituting the Parameters into the equation :

Area of triangle = 1/2 × 16 × 1/8 = 1 in²

Therefore, the area of the triangle is 1 in²

Answer:

3 is the slope

Step-by-step explanation:

Mathematically, a linear function can be represented in the form;

y = mx + c

where m represents the slope and c is the y-intercept of the function.

In the equation given in the question above;

The slope of the equation is 3

What this means is that, the average rate of change between two points in the plot of the linear function is 3

Mathematically speaking, we mean that given two years and their corresponding average haircut prices, then the average rate of change between these two years on the plot is 3

The sequence for the derivation of tangent sum identity is option I --> IV --> II --> III.

The trigonometric identities is the relationship between the different trigonometric ratios. These trigonometric identities are the basic formulae that are true for all the values of the reference angle.

For the given situation,

The derivation for the tangent sum identity is given in the table below.

The derivation follows the steps,

[tex]\frac{sin(x+y)}{cos(x+y)}[/tex]

we know that, [tex]sin(x+y) = sinx cosy + cosx siny[/tex] ,

[tex]cos(x+y)=cosxcoxy - sinxsiny[/tex] and

[tex]\frac{sinx}{cosx}=tanx[/tex]

⇒ [tex]\frac{sinxcosy + cosxsiny}{cosxcosy-sinxsiny}[/tex]

Divide each term by [tex]cosxcosy[/tex]

⇒ [tex]\frac{\frac{sinxcosy}{cosxcosy} +\frac{cosxsiny }{cosxcosy} }{\frac{cosxcosy}{cosxcosy} -\frac{sinxsiny}{cosxcosy} }[/tex]

⇒ [tex]\frac{tanx+tany}{1-tanxtany}[/tex]

Hence we can conclude that the derivation of tangent sum identity is option I --> IV --> II --> III.

Answer:

The taxi costs $1 just to get into a taxi

Step-by-step explanation:

The base cost the taxi charges for it to be hired is $1 which is the point on the graph where the line intercepts the y-axis. At that point, distance or miles travelled is 0.

Therefore, we can conclude that the taxi would charge a customer for just to get a taxi, and the total cost will be dependent on the additional charges paid in addition based on the number of miles the customer will be driven to their destination.

The $1 is just the charge fee paid by the customer in addition to the per-mile charge he would pay.
