Answer:

The midpoint between A(-7, 5) and B (7, 3) is: (0, 4)

Step-by-step explanation:

Given the points

Determining the midpoint between A(-7, 5) and B (7, 3)

[tex]M.P_{AB\:}=\:\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-7,\:5\right),\:\left(x_2,\:y_2\right)=\left(7,\:3\right)[/tex]

             [tex]=\left(\frac{7-7}{2},\:\frac{3+5}{2}\right)[/tex]

             [tex]=\left(0,\:4\right)[/tex]

Therefore, the midpoint between A(-7, 5) and B (7, 3) is: (0, 4)

Answer:

17° and 73°

Step-by-step explanation:

For two complementary angles, the sum of angles is equal to 90 degrees.

Let other angles = x

First angle = 5+4x ...(1)

ATQ,

5+4x+x=90 ...(2)

Equation (1) and (2) shows the equations for the given problems.

5+5x=90

5x = 85

x = 17°

Other angle = 17

First angle = 5+4x

= 5+4(17)

= 73°

So, the other two angles are 17° and 73° respectively.

Answer:

A boat would need 21 liters to cover the distance of 84 km.

Step-by-step explanation:

Given

A boat can travel 496 km on 124 liters of fuel.

To determine

How much fuel will it need to go 84 km?

It is stated that:

Distance covered in 124 liters of fuel = 496 km

Thus,

Unit rate = 496 km / 124 liters

               = 4 km per liter

Thus,

The distance covered in 1 liter = 4km

In order to determine the distance covered in 84 km, all we need is to divide 84 km by 4.

i.e.

The fuel needed to go 84 km = 84 / 4 = 21 liters

Therefore, a boat would need 21 liters to cover the distance of 84 km.

Answer:

Answer:

There was 20 questions on the test.

She got 3 wrong.

Step-by-step explanation:

[tex]\frac{85}{100} = \frac{17}{20}[/tex]

20 - 17 = 3

There was 20 questions on the test.

She got 3 wrong.

Here, we are required to determine how long would it take Paul to walk 6.25 km.

The Time, t = 1.25hours (i.e 1 hour and 15mins)

Since Paul's average speed is 5km per hour = 5km/h

Speed is defined as the distance covered(in this case, km) per unit time(in this case, hours)

Therefore, Speed = Distance/Time.

Therefore, 5km/h = 6.25km/Time.

Therefore, the time taken for Paul to walk 6.25 km is ;

Time = (6.25/5)hours

Time, t = 1.25hours (i.e 1 hour and 15mins)

Answer:

DB = 26

Step-by-step explanation:

Remember:

☆The equation in finding the value of x would be 3x - 2 = 2x + 3.

☆Let's solve the equation.

[tex] \: \: \: \: \: \: \: \: \: 3x - 2 = 2x + 3 \\ \frac{ - 2x \: \: \: \ = - 2x}{x - 2 = 3} \\ \frac{ \: \: \: \: \: + 2 = + 2}{x = 5} [/tex]

☆Now that we found the value of x, we are going to plug in for AE and EC.

[tex]AE ; \\ 3x - 2 \\ 3(5) - 2 \\ 15 - 2 \\ 13 \\ \\ \\ \\ and \\ \\ \\ \\ \\ EC; \\ 2x + 3 \\ 2(5) + 3 \\ 10 + 3 \\ 13[/tex]

☆AE and EC each measure 13. To find the length of AC, you will have to add AE and EC. [tex]13 + 13 = 26[/tex]

The length of AC is 26. And since we know that AC is congruent (equal) to DB, meaning they measure the same. DB length is also 26.

Answer:

t = 10

Step-by-step explanation:

Proportions

D is directly proportional to t squared. This can be written as:

[tex]D = kt^2[/tex]

Where k is the proportionality constant. It can be calculated by substituting the given condition in the formula, when t=4, D=8:

[tex]8 = k4^2=16k[/tex]

Solving for k:

[tex]k=\frac{8}{16}=\frac{1}{2}[/tex]

Thus, the proportional relationship is:

[tex]\displaystyle D = \frac{1}{2}t^2[/tex]

When D=50, the value of t can be found by solving for t:

[tex]\displaystyle 50 = \frac{1}{2}t^2[/tex]

Multiplying by 2:

[tex]t^2=100[/tex]

Taking the square root:

[tex]t=\sqrt{100}[/tex]

The positive value of t is:

t = 10

Answer:

$2,989.12

Step-by-step explanation:

The correct answer to the given question is $2,989.12. The monthly net pay is $2,989.12, when the gross monthly income is $3,750.

The deduction from the gross income is almost 20.29%.

The gross income is multiplied by 20.29% and then the answer is deducted from the gross income which gives monthly net pay as a result

$3,750 * 20.29% = $760.875

$3,750 - $760.875 = $2,989.12

Your monthly net pay is $2,989.12

Answer:

h = 11242 km

Step-by-step explanation:

A flight with this altitude can be modeled by the function :

[tex]h = -0.17t^2 + 187t + 61000[/tex] ....(1)

Where h is the altitude in meters and t is flight time in seconds.

We need to find the highest altitude reached by the space plane.

Put [tex]\dfrac{dh}{dt}=0[/tex]

So,

[tex]\dfrac{d(-0.17t^2 + 187t + 61000)}{dt}=0\\\\-0.34t+187=0\\\\0.34t=187\\\\t=\dfrac{187}{0.34}\\\\t=550\ s[/tex]

At t = 550 seconds the space plane reaches the highest altitude.

Put t = 550 s in equation (1).

[tex]h = -0.17(550)^2 + 187(550)+ 61000\\\\h=112425\ m\\\\h=112.42\ km[/tex]

Hence, the highest altitude reaches by the space plane is 11242 km.

Answer:

78 persons

Step-by-step explanation:

Given

[tex]Budget = 3000[/tex]

[tex]Clean\ up = 100[/tex]

[tex]Rate = 37\ per\ person[/tex]

Required

Determine the maximum number of person that can be invited

Let the number of persons be p.

If the hall charges $37 for 1 person, then it will charge $37p for p persons.

So:

[tex]Charges = 37p[/tex]

The expression becomes:

[tex]Clean\ up + Charges = Budget[/tex]

Substitute values for Clean up, Charges and Budget

[tex]100 + 37p = 3000[/tex]

Subtract 100 from both sides

[tex]100 - 100 + 37p = 3000 - 100[/tex]

[tex]37p = 3000 - 100[/tex]

[tex]37p = 2900[/tex]

Make p the subject

[tex]p = \frac{2900}{37}[/tex]

[tex]p = 78.378[/tex]

Round down

[tex]p = 78[/tex]

Hence, they can only invite 78 people to stay within budget

Answer: 22.8 because you calculate the percentage  of number 30

Step-by-step explanation:

Answer:

22.8

Step-by-step explanation:

To find the percentage of a number, first change the percentage to a decimal and then multiply.

76% as a decimal is 0.76 (Divide the percentage by 100 to get decimal value)

30 x 0.76 = 22.8

(To multiply numbers when using decimals, first disregard the decimal altogether and multiply as normal - 30x76=2280 - then put in the decimal place at the end. In this case there were two digits after the decimal, so we place the decimal two digits from the right, turning 2280 to 22.80)
