labourers​

Answers

Answer 1

Answer:

12 or 13

Step-by-step explanation:

Answer 2

14 labourers complete the job in 3 days.

What is the ratio?

The ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Given data as :

It takes 6 labourers 7 days to complete a job,

Amount of work completed by 6 labourers over 7 days  = 1

Six labourers completed part of the work in one day = 1/7

one labourers completed part of the work in one day  = (1/6)(1/7) = 1/42

Let x number of labourers complete the job in 3 days.

x × 3 ×(1/42) = 1

x = 42/3

x = 14

Hence, 14 labourers complete the job in 3 days.

Answer:

Pythagorean Theorum:

16ft

Step-by-step explanation:

pythagorean theorum states a^2+b^2=c^2

it only works for right triangles, c is the hypotenuse, a and b are the legs

so to find b we plug in the info we have!

7.8^2+b^2=17.8^2

next we simplify:

60.84+b^2= 316.84

subtract 60.84 from both sides to isolate the variable:

b^2=256

square root both sides

b=16

16ft is the answer

Radius r= 5 ft

The volume of a cylinder is given as

V= πr^2h

Substitue

V= 3.142*5^2*27

V= 3.142*25*27

In an 80/20 mortgage, what is the first mortgage used for

A. 80% down payment
B. 20% interest rate
C. 20% down payment
D. 80% of the home’s value

Answers

Answer: D. 80% of the home’s value

============================================================

Explanation:

As you probably expect, the first number 80 refers to the percentage the first loan covers. If the house is say $100,000, then the first loan is $80,000 while the second loan is the remaining $20,000.

An 80/20 mortgage, or similar, will have two monthly payments because you are getting two mortgages bundled together. Usually you should pay a down payment, though it may likely depend on your credit history. Those with good credit will pay less or no down payment, compared to those with worse credit will have to pay more down payment. A good rule of thumb is that 20% of the home's value is made as down payment, though this isn't what the "20" in "80/20" is referring to.

An 80% down payment is extremely high and unreasonable. Not many people have that kind of money laying around. A similar story applies to a 20% interest rate which is incredibly large for a mortgage rate (typically they are in the single digits such as 3%).

The volume of the prism is 72 cubic feet. Find the missing height of the triangular prism, and the surface area.

Answers

Answer:

h = 12

surface area = 192

Step-by-step explanation:

Volume of this prism = 72

The base triangle has an area of B * h/2

The base = 6

The height in red = 2

Area = 1/2 * 6 * 2

Area = 6 ft^2

The volume = B * h = 72

The base = 6

6* h = 72

h = 72/6

h = 12

The surface area = 2 triangles + the rectangle face closest to us + the rectangular face whose width is 4 + rectangular face whose with is 5

The surface area = 2 * 6 + 6* 12 + 4*12 + 5 * 12

The surface area = 12 + 72 + 48 + 60

The surface area = 192 square feet.

H=12 I feel like it this

A circles diameter is 12 inches what is the circles circumference using 3.14 rounded to the nearest tenth

Answers

37.7 that is the exact number hopes this helps

Answer:

[tex]37.7in.[/tex]

Step-by-step explanation:

The circumference of a circle is: [tex]C=2\pi r[/tex]

However, the question wants us to use 3.14 instead of [tex]\pi[/tex].

We are given 12 inches as the diameter of the circle.

We want the radius, which is half of the diameter.

The radius of the circle is 6 inches.

Now that we have the radius, we plug and chug.

[tex]C=2*3.14*6in.\\C=6.28*6in.\\C=37.68in.\\[/tex]

However, the question wants us to round the answer to the nearest tenth.

Therefore, the new answer is: [tex]37.7in.[/tex]

Write down the correct type of angle for angles A to E.

Answers

Answer:

Angle A- Obtuse angle

Angle B- Right angle

Angle C- Reflex angle

Angle D- Reflex angle

Angle E- Acute angle

Angle A is Obtuse angle, Angle B is  Right angle, Angle C is Reflex angle, Angle D is Reflex angle and Angle E is Acute angle

What are Angles?

An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

Obtuse angle is any angle greater than 90°

A right angle is an angle measuring exactly 90°

A reflex angle is an angle that is more than 180 degrees and less than 360 degrees.

Any angle that measures greater than 0° and less than 90° is called an acute angle.

By the definitions of these the angles are

Angle A- Obtuse angle

Angle B- Right angle

Angle C- Reflex angle

Angle D- Reflex angle

Angle E- Acute angle

Hence, Angle A is Obtuse angle, Angle B is  Right angle, Angle C is Reflex angle, Angle D is Reflex angle and Angle E is Acute angle

1. Isosceles Triangle The two equal sides of an isosceles triangle are each 42

centimeters. If the base measures 30 centimeters, find the height and the

measure of the two equal angles. Round your answer to the nearest tenth.

Answers

Answer:

1. H = 29 cm

2. θ = 44°

Step-by-step explanation:

1. We can find the height of the triangle by considering the isosceles triangle as two right triangles. The height can be found by using Pitagoras:

[tex] L^{2} = H^{2} + B^{2} [/tex]

Where:

L: is the sides of the isosceles triangle = 42 cm

B: is the base = 30 cm

H: is the height =?

Then, the height is:

[tex] H = \sqrt{L^{2} - B^{2}} = \sqrt{(42 cm)^{2} - (30 cm)^{2}} = 29.4 cm = 29 cm [/tex]

2. The two equal angles (θ) can be found using the following trigonometric identity:          

[tex] cos(\theta) = \frac{B}{L} [/tex]

[tex] \theta = cos^{-1}(\frac{30 cm}{42 cm}) = 44.4^{\circ} = 44^{\circ} [/tex]

Hence, the two equal angles are 44°.

A curious statistics student cannot get enough statistics, so he decides to analyze the percentage of students sleeping in his statistics class. He discovers that of the 30 students in his class, 47% of the students were asleep at some point during the class period. Assuming the 30 students is less than 10% of all the students taking statistics in his school, and assuming the 30 students in the class were randomly assigned to the class, what model would he use to analyze the percentage of sleeping statistics students

Answers

Answer:

c) N(.47, .09)

Step-by-step explanation:

Options to the question are "a) N(.30, .10), b) N(.30, .09). c) N(.47, .09), d) N(.47, .008), e) N(.30, .008)"

Pο = 47% = 0.47

n = 30

Mean = Pο = 0.47

S.D = Pο(1-Pο) / n

S.D = 0.47 * 0.53 / 30

S.D = 0.09

Thus, the percentage of sleeping statistics of students follows a Normal distribution with mean = 0.47 and S..D = 0.09
