Answers

Answer 1

Answer:

∠ S = 58° , ∠ T = 64° , ∠ Q = 58°

Step-by-step explanation:

the sum of the 3 angles in Δ DQS = 180° , that is

∠ Q + ∠ 1 + 90° = 180°

∠ Q + 32° + 90° = 180°

∠ Q + 122° = 180° ( subtract 122° from both sides )

∠ Q = 58°

given ST = TQ , then Δ STQ is isosceles with base angles congruent, that is

∠  S = ∠ Q = 58°

the sum of the 3 angles in Δ STQ = 180° , that is

∠ T + ∠ S + ∠ Q = 180°

∠ T + 58° + 58° = 180°

∠ T + 116° = 180° ( subtract 116° from both sides )

∠ T = 64°

8 men can complete the project in 24 days in how many days 12 men can complete the same project

Answers

Answer:

16days

Step-by-step explanation:

This is an inverse proportionality

Let the number of men be m

Let the time taken in days be d

Hence m ∝ 1/d

m = k/d

If 8 men can complete the project in 24 days, then;

8 = k/24

k = 8*24

k = 192

To determine the time it will take 12 men to complete the same job, we will say;

m = k/d

12 = 192/d

d = 192/12

d = 16

Hence it will take 12men 16days to finish the same job

The area of a triangle is 174 square inches. The base is 29 inches. What is the height in inches? Do not include units in your answer.

Answers

Answer:

Your answer would be 6

Step-by-step explanation:

Area=174

Base=29

174 divided by 29

Equals 6

6 times 29

Equals 174

So since 29 times 6 gave you 174 which is your area, your answer would be 6 since it is the missing height to your problem.

:)

Answer: 12

Step-by-step explanation:

We can use the formula for the area of a triangle, to help us find the height:

Area=12⋅b⋅h

Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:

174=12⋅29⋅h

Isolate h by multiplying both sides by 2 and dividing both sides by 29.

hh=2⋅17429=12

The height is 12 inches.

Answers

Answer:

$434

Step-by-step explanation:

Gross Pay

$7.75 per hour40 hours per weekPay received every 2 weeks

⇒ Total gross pay = 7.75 × 40 × 2 = $620

Deductions

Medical insurance = 8%Taxes = 12%Retirement = 10%

⇒ Total deductions = 8% + 12% + 10% = 30%

Net Pay

Net Pay = Total Gross Pay - Total deductions

             = $620 - (30% of $620)

             = $620 - (0.3 × $620)

             = $620 - $186

             = $434

Therefore, Cory's net pay will be $434.

The radius of a cone is 4.9 cm and its height is 10 cm. Find the volume of the cone to the
nearest tenth. Use 3.14 for pie

Answers

Answer:

V = 251.3

Step-by-step explanation:

Volume of a Cone formula:

V = πr²(h/3)

Given:

r = 4.9

h = 10

Work:

V = πr²(h/3)

V = 3.14(4.9²)(10/3)

V = 3.14(24.01)(10/3)

V = 251.3

V = 251.432132 m3 is the answer to the equation

A home is purchased for $ 794,000 with a 16% down payment. Find the monthly payment if the mortgage is 7.22% for 19 years. Round your answer to two
decimal places, if necessary,

Answers

Answer:

The monthly payment will be of $11,485.37

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

A home is purchased for $ 794,000 with a 16% down payment.

So the value of the loan, that is, the amount subject to interest, will be given by:

[tex]P = (1-0.16)*794000 = 0.84*794000 = 666960[/tex]

How much will the interest accumulate to?

7.22% of interest means that [tex]r = 0.0722[/tex]

19 means means that [tex]t = 19[/tex]

Monthly means that [tex]n = 12[/tex]

So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(t) = 666960(1 + \frac{0.0722}{12})^{12*19}[/tex]

[tex]A(t) = 2618664.5[/tex]

Monthly payment:

2618664.5 divided in 19*12 payments. So

2618664.5/(19*12) = 11485.37

The monthly payment will be of $11,485.37

A vacuum flask (for keeping drinks hot) is modelled as a closed cylinder in which the internal radius is r cm and the internal height is h cm.
The volume of the flask is 1000 cm³. A flask is most efficient when the total internal surface area, A cm², is a minimum.

(i) Show that A = 2π2²+ 2000/2

(ii) Given that r can vary, find the value of r, correct to 1 decimal place, for which A has a stationary value and verify that the flask is most efficient when r takes this value.

Answers

(i) To find the total internal surface area, we need to calculate the area of the curved surface and the areas of the top and bottom circles.

The curved surface area of the cylinder is given by the formula:

A_curved = 2πrh

The area of the top and bottom circles is given by the formula:

A_circles = 2πr²

The total internal surface area is the sum of the curved surface area and the areas of the top and bottom circles:

A = A_curved + A_circles

= 2πrh + 2πr²

Given that the volume of the flask is 1000 cm³, we have the equation:

πr²h = 1000

Solving for h, we get:

h = 1000 / (πr²)

Substituting this value of h into the equation for A, we have:

A = 2πrh + 2πr²

= 2πr(1000 / (πr²)) + 2πr²

= 2000/r + 2πr²

Simplifying further, we get:

A = 2000/r + 2πr²

= 2πr² + 2000/r

(ii) To find the value of r for which A has a stationary value, we differentiate A with respect to r and set the derivative equal to zero.

dA/dr = 4πr - 2000/r² = 0

Multiplying through by r², we get:

4πr³ - 2000 = 0

Solving for r, we have:

4πr³ = 2000

r³ = 2000 / (4π)

r = (2000 / (4π))^(1/3)

Calculating this value to one decimal place, we get:

r ≈ 3.4 cm

To verify that the flask is most efficient when r takes this value, we need to check the second derivative of A with respect to r.

d²A/dr² = 12πr² + 4000/r³

Substituting the value of r, we have:

d²A/dr² = 12π(3.4)² + 4000/(3.4)³

Calculating this value, we find that it is positive, indicating a minimum. Therefore, the flask is most efficient when r ≈ 3.4 cm.
