Answer:

The time period will be ;

10 am to 10 : 52 am

(Then she will catch up at exactly 10:52 am , 30 seconds)

Step-by-step explanation:

In this question, what we simply want to calculate is the amount of time it will take Riko to cover same distance as Yuto.

Mathematically, at any point in time;

Speed = distance/time

Let the time we are looking for be x minutes

At x minutes , Riko will be at a distance of 0.35 * x = 0.35x miles

At x minutes, Yuto will be at a distance of 5.25 miles + 0.25 * x = (5.25 + 0.25x) mikes

Kindly note that, at the time x minutes, the distance covered would have been equal;

Thus;

0.35x = 5.25 + 0.25x

0.35x -0.25x = 5.25

0.1x = 5.25

x = 5.25/0.1

x = 52.5 minutes

Over a time period of 52.5 minutes, Riko will be behind her brother ;

Since Yuto left at 10 am, the time period will be ;

10am to 10:52 am

Answer:

Sample Response: The solution means that Riko will be behind Yuto from the time she leaves the house, which corresponds to t = 0, until the time she catches up to Yuko after 52.5 minutes, which corresponds to t = 52.5. The reason that t cannot be less than zero is because it represents time, and time cannot be negative.

Answer:

[tex]y = 32x[/tex]

The rate is 224 ft/s

Step-by-step explanation:

Solving (a):

Given

[tex](x_1,y_1) = (1,32)[/tex]

[tex](x_2,y_2) = (2,64)[/tex]

Required

Determine the linear equation

First, we need to determine the slope using

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

[tex]m = \frac{64 - 32}{2 - 1}[/tex]

[tex]m = \frac{32}{1}[/tex]

[tex]m = 32[/tex]

The equation is then calculated using:

[tex]y - y_1= m(x - x_1)[/tex]

[tex]y - 32= 32(x - 1)[/tex]

[tex]y - 32= 32x - 32[/tex]

Add 32 to both sides

[tex]y - 32 + 32= 32x - 32 + 32[/tex]

[tex]y = 32x[/tex]

Solving (b):

Given

[tex]x = 7[/tex]

Required

Determine y

We have that:

[tex]y = 32x[/tex]

Substitute 7 for x

[tex]y=32 * 7[/tex]

[tex]y=224[/tex]

Hence, the rate is 224 ft/s

The slope of the table is 2

From the table, we have the following points:

(x,y) = (0, 4) and (1,7)

The slope is then calculated as:

m = (y2 - y1)/(x2 - x1)

Substitute known values

m = (7 - 4)/(1 - 0)

Evaluate the differences

m = 3/1

Divide

m = 2

Hence, the slope of the table is 2

Answer:

Approximately $103.37 per day

Step-by-step explanation:

As April has 30 days, we have to add together $523, $2340, and $238 to get the total balance for the entire month. In this case, the total balance is $3101. Now, referring back to April having 30 days, $3101÷30 days=$103.366666666 a day, when rounded to two decimal places, it equals $103.37 a day. So, the account's mean daily balance for April is approximately $103.37 a day.

Hopefully the explanation and the answer helps!

The mean daily balance will be 736.77

Weighted mean is the mean where some of the value contributing more than the other values.

Weighted mean can be calculated by dividing the sum of frequencies and value by the sum of the frequencies.

weighted mean= ∑fₙxₙ/∑fₙ

where f is the frequency and x is the value.

So according to asked question,

in April, balance is in such a way that $523 for 23 days, $2340 for only 4 days, and $238 for only 3 days.

x₁=$523   ,   f₁=23

x₂=$2340   ,   f₂=4

x₃=$238   ,   f₃=3

weighted mean= sum of the product frequency and value/sum of frequency

=  ∑fₙxₙ/∑fₙ

= ((523*23)+(2340*4)+(238*3))/(23+4+3)

=22103/30

=736.7666≅736.77

Therefore the mean daily balance will be $736.77.

Step-by-step explanation:

Answer: 15/7 2 1/7

Step-by-step explanation: First divide 8x-3=x+12 Then add 3 to both sides.

8x=x+15 Subtract x from both sides. 7x=15 Then divide again so 7/7 and 15/7. If you simplify it become 2 1/7

Answer:

x = 15/7

Step-by-step explanation:

Reduce the fraction with 2

8x - 3 = x + 12

Move variable to the left-hand side and change its sign

8x - x - 3 = 12

Move constant to the right-hand side and change its sign

8x - x = 12 + 3

collect like terms

7x = 12 + 3

Add the numbers

7x = 15

Divide both sides of the equation by 7

Solution: x = 15/7

Alternate form

x = 2 1/7, x = 2.142857

Answer:

The cost price of a radio is Rs 8665

Step-by-step explanation:

There is a relation between the cost price, loss amount, and the selling price.

In the loss, the cost price must be greater than the selling price.

In our question:

The selling price is Rs 7777

The loss is Rs 888

We need to find the cost price

Let us use the rule above

∵ The selling price = Rs 7777

∵ The loss = Rs 888

→ Substitute them in the rule above to find the cost price

∴ The cost price = 7777 + 888

∴ The cost price = 8665

∴ The cost price of a radio is Rs 8665

Answer:

-1/3

Step-by-step explanation:

slope is rise over run so on this one you had to count down to -2 for the rise and count to 6 then simplify to make -1/3

The slope of the line will be equal to 1 / 3. The correct option is D.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is the ratio of the rise to the run.

The formula to calculate the slope of the line is,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The given coordinates of the point passing through the line are (-3,4) and (3,2).

The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 4- 2 ) / ( 3 + 3 )

Slope = 2 / 6

Slope = 1 / 3

Therefore, the slope of the line will be equal to 1 / 3. The correct option is D.

Answer:

Your final equation should be y = 25 x + 45

Step-by-step explanation:

    The equation y = m x + b represents any linear equation. the m stands for slope, and the b stands for the y- intercept (when x = 0). To fill in the blanks you need to figure out which piece of information is which.

    Let's start with the y intercept. y, in this equation stands for the cost. And since the y intercept is when x equals zero, you need the cost that doesn't relate to the time the plumber was at the house. That would be the 45 dollar fee you pay the plumber to go to your house.

    Next, let's explain why the 25 dollars represents m (The slope) of this equation. You have to pay the plumber 25 dollars for every hour he spends at your house, so this cost goes up by 25 dollars every hour.

Your final equation should be y = 25 x + 45
