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.

What is work and time relationship?Work is the effort applied to produce a deliverable or accomplish a task. A certain amount of time (T) is taken to complete a certain work (W).
Work Done = Time Taken × Rate of Work.
Rate of Work = 1 / Time Taken.
Time Taken = 1 / Rate of Work.
According to the question
Dan and Joan were able to clean the attic in 7 hours together
i.e
Rate of Dan = D
Rate of Joan = J
now,
Rate of Work = 1 / Time Taken.
D + J = [tex]\frac{1}{7}[/tex]
It takes Joan 9 hours to complete the same job alone
i.e
J = [tex]\frac{1}{9}[/tex]
Rate of Dan :
D + J = [tex]\frac{1}{7}[/tex]
D + [tex]\frac{1}{9}[/tex] = [tex]\frac{1}{7}[/tex]
D = [tex]\frac{1}{7}[/tex] - [tex]\frac{1}{9}[/tex]
D = [tex]\frac{2}{63}[/tex]
Therefore , Time taken by Dan to complete the same job
As,
Time Taken = 1 / Rate of Work.
Time taken by Dan = [tex]\frac{63}{2}[/tex]
= 31.5 hr
Hence, It would take 31.5 hours for Dan to complete the same job.

If Paul's average speed is 5 km per hour, how long would it take Paul to
walk 6.25 km?
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)

A boat can travel 496 km on 124 liters of fuel. How much fuel will it need to go 84 km?
____liters
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.

In 2004, the highest space plane flight was made by Brian Binnie in Space Sip One. A flight with this altitude can be modeled by the function h = -0.17t^2 + 187t + 61000, where h is the altitude in meters and t is flight time in seconds. What was the highest altitude reached by the space plane?
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.

D is directly proportional to t2 When t = 4, D = 8 Find the positive value of t when D = 50
Answer: either 46 or 25 is your answer
Step-by-step explanation: Brainliest pls
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

Each ice cream sundae must include 2 different flavors of ice cream; what is the probability that the next customer's sundae will have vanilla and chocolate (in either order)
Answer:
1/30
Step-by-step explanation:
let, vanilla be the first ice cream.
hence, the probability of choosing vanila= 1/6
let, chocolate be the second ice cream.
hence, the probability of choosing chocolate=1/5
hence, the probability that the next customer's sundae will have vanilla and chocolate (in either order)= (1/6)×(1/5)

Mark and Heather Starr are celebrating their 25th anniversary by having a reception at a local reception hall. They have budgeted $3,000 for their reception. If the
reception hall charges a $100 cleanup fee plus $37 per person, find the greatest number of people that they may invite and still stay within their budget.
Mark and Heather can invite at most people to the reception
(Round down to the nearest whole person)
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

AE = 3x - 2 and EC = 2x + 3 then DB =
#5
Answer:
DB = 26
Step-by-step explanation:
Remember:
AE ≅ ECAC ≅ DB☆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.
What is 76% of 30? show your work AWNSER ASAP
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)

If your gross monthly income will be $3,750, you need to determine the net pay for your monthly budget. Your monthly net pay is
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
