The diagonal of a square measured 7 square root of 2 cm. Then the length of side of square is 7 cm

Solution:

Given that,

The length of diagonal of a square is [tex]7 \sqrt{2}[/tex] cm

The figure is attached below

So length of diagonal = AC = [tex]7 \sqrt{2}[/tex] cm

Let the length of sides of the square be ‘a’

Since, the diagonal and the sides are forming a right angled triangle

So, we can use Pythagoras theorem,

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

In triangle ABC, AC forms the hypotenuse and BC is the perpendicular and AB is the base

So above Pythagoras theorem definition,

[tex](\mathrm{BC})^{2}+(\mathrm{AB})^{2}=(\mathrm{AC})^{2}[/tex]

[tex]\begin{array}{l}{(a)^{2}+(a)^{2}=(7 \sqrt{2})^{2}} \\\\ {2 a^{2}=98} \\\\ {a^{2}=98 \div 2=49} \\\\ {a=\sqrt{49}=7}\end{array}[/tex]

Hence, the length of the square is 7 cm

Using two unit multiplier 628 km is equal to 62800000 cm

Solution:

628 kilometer to centimeter

We will go from kilometers to meters to centimeters.

Start by putting 628 km over 1:

[tex]\frac{628 km}{1}[/tex]

We want to get rid of km and bring in m.

We know that 1000 m = 1 km.

Since km is in the numerator, we will make the  first unit multiplier by putting 1 km in the  denominator and 1000 m in the numerator, so the  km will cancel. So we multiply by the unit multiplier,

[tex]\frac{628 km}{1} \times \frac{1000m}{1km}[/tex]

Now the km's will cancel:

[tex]\frac{628}{1} \times \frac{1000m}{1}[/tex]

Now we want to get rid of m and bring in cm.

We know that 100 cm = 1 m.

Since meter is in the numerator, we will make the  first unit multiplier by putting 1 meter in the  denominator and 100 cm in the numerator, so the  meter's will cancel. So we multiply by the unit  multiplier

[tex]\frac{100cm}{1m}[/tex]

[tex]\frac{628}{1} \times \frac{1000m}{1} \times \frac{100cm}{1m}[/tex]

We cancel the m's and we end up with:

[tex]628 \times 1000 \times 100 cm[/tex]

= 62800000 cm

Thus 628 km is equal to 62800000 cm

Final answer:

To convert 628 kilometers to centimeters, multiply by the conversion factors for kilometers to meters and then meters to centimeters, leading to 62,800,000 centimeters.

Explanation:

To convert 628 kilometers to centimeters, we need to apply two unit multipliers. The first conversion factor is 1 kilometer = 1000 meters, and the second conversion factor is 1 meter = 100 centimeters.

First, we convert kilometers to meters:

628 km × 1000 m/km = 628,000 meters

Then, we convert meters to centimeters:

628,000 m × 100 cm/m = 62,800,000 centimeters

Therefore, 628 kilometers is equal to 62,800,000 centimeters.

The equivalent time to 2 h 26 min is 146 min ⇒ 2nd answer

Step-by-step explanation:

Let us revise how to change a time from hours and minutes to minutes

Ex: change 3 h 13 min to min, Multiply 3 by 60 and then

and the answer by 13 [(3 × 60) = 180 + 13 = 193], then

3 h and 13 min = 193 min

Let us do the same with your problem

2 h 26 min

∵ The number of hours = 2

∵ 1 hour = 60 minutes

∴ 2 hours = 2 × 60 = 120 minutes

∵ The number of minutes = 26

- Add 120 to 26

∴ 2 h 26 min = 120 + 26 = 146

The equivalent time to 2 h 26 min is 146 min

To find the duration of workout plans A and B offered by Shen, we set up a system of linear equations and solved them. Both plans last 1.25 hours each.

Let us denote the duration of workout Plan A as A hours and Plan B as B hours. We can use the provided information to set up a system of linear equations representing the total training time on each day. On Friday, 3 clients did Plan A and 5 did Plan B for a total of 10 hours, leading to the equation 3A + 5B = 10. On Saturday, 6 clients did Plan A and 2 did Plan B for a total of 10 hours, resulting in the equation 6A + 2B = 10.

To solve this system of equations, we can use substitution or elimination. Multiplying the first equation by 2 gives us 6A + 10B = 20. Then we can subtract the Saturday equation from this to find the value of B:

Now that we know the duration of Plan B, we can plug this into either of our original equations to find the duration of Plan A. Let's use the Friday equation for this purpose:

As it turns out, both workout plans last the same amount of time, 1.25 hours each.

Answer:

7

Step-by-step explanation:

We know, slope = rise/ run. We can use this slope formula to find out the value of every pizza.

So, 58-25/( 5-2) = 33/ 3= 11

So, every pizza costs $11

Now, A customer pays $80 for a number of pizzas. So, if we divide 80 by 11 we can find the value of unknown number of pizzas he ordered.

So, 80/11= 7.27

Here, pizzas can't be fraction and cost of a delivery fee is added to the cost. So, we can remove the fraction.

So, the customer ordered 7 pizzas for $80.

The number line which represents the solution of 2.5 -1.2 x < 6.5 - 3.2 x is " A number line from negative 5 to 5 in increments of 1. An open circle is at 2 and a bold line starts at 2 and is pointing to the left "

Step-by-step explanation:

On the number line, when we represent the solution of an inequality:

∵ 2.5 -1.2 x < 6.5 - 3.2 x

- Add 3.2 x to both sides

∴ 2.5 + 2 x < 6.5

- Subtract 2.5 from both sides

∴ 2 x < 4

- Divide both sides by 2

∵ x < 2

∴ The solution of the inequality is x < 2 ⇒ all numbers less than 2

∵ The sign of inequality is <

- By using the points above

∴ The solution represented on the number line by an open circle

   is at 2 and the line starts at 2 and pointing to the left

The number line which represents the solution of 2.5 -1.2 x < 6.5 - 3.2 x is " A number line from negative 5 to 5 in increments of 1. An open circle is at 2 and a bold line starts at 2 and is pointing to the left "

Mara's family's average rate of travel, R, is calculated by dividing the total distance of 239.4 miles by the total time of 4.5 hours and then rounding to the nearest mile per hour.

To determine Mara's family's average rate of travel, R, you should start by calculating the total travel time. They started at 9:10 a.m and ended at 1:40 p.m, which is a span of 4 hours and 30 minutes, or 4.5 hours when converted to decimals to match the units of the distance traveled. Now use the formula for average speed, which is distance divided by time.

So, R = total distance / total time.

Substitute the given values into this formula to arrive at R = 239.4 miles / 4.5 hours. To find the average rate of travel, rounded to the nearest mile per hour, you would complete the division and then round the result.

Example Equation:

R = 239.4 miles / 4.5 hours

Answer:

a) The very first one where the line starts to the left

b) m=125.82

c) 320.81 thousand dollars

Step-by-step explanation:

a) The point on the graph who corresponds to x=3 years and Salary=$200,000 is the very first one where the line starts to the left

b) If a line is given by Y=mx+b, m represents the slope of the line. In this case, m=125.82 which can be interpreted as the rate of growth of the salary per year in thousands of dollars. A doctor can expect to earn 125.82 thousand dollars more than the previous year.

c) If we use the given regression line Y=125.82x-182.47 and make x=4, we get

y=125.82 (4)-182.47 =320.81 thousand dollars

Danielle earned $969 last week if she sold $4,400 in electronics merchandise

Given that, Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.  

She also earns a base salary of $650 per week.  

We have to find how much did she earn last week if she sold $4,400 in electronics merchandise?  

Now, we know that, earned amount = base salary + commission

Given that she earns a 7.25% commission on everything she sells

So commission earned for selling $ 4400 is given as:

commission earned = 7.25 % of 4400

[tex]\text { commission earned }=\frac{7.25}{100} \times 4400=7.25 \times 44=319[/tex]

Earned amount = base salary + commission = 650 + 319 = 969

Hence, she earned $969 last week

Answer:

6 tickets

Step-by-step explanation:

you can't round it so just says 6 tickets with left over money

The number of tickets Roberto can buy with his $200 is 6 tickets.

The total amount Roberto has to spend on tickets = $200.

The cost of each ticket = $30.

We need to find the number of tickets Roberts can buy for the hockey game.

Total amount to spend on ticket = $200.

Cost of each ticket = $30.

The number of tickets possible to buy with $200 :

= 200 / 30

= 6.67 tickets.

We can not have 6.67 tickets so we can say 6 tickets.

Since each ticket cost $30, the total cost for the ticket is :

= 6 x $30

= $180

So after buying 6 tickets Roberto will be left with $20.

The number of tickets Roberto can buy with his $200 is 6 tickets.
