When you want to round up or down numbers focus on only two digits,which is the digit in place that you are rounding to and the digit to it's immediate right which tells you whether to round up or down.When the number you are rounding is between 0-4, you round down to the next lowest number. When the number is 5-9,you round the number up to the next highest number.
For example: If you have 25 and you want to round it up then it will be rounded up to 3 because 5 can be rounded up to the next number which is 2 to make it 3.But when you have 23,then you can't round it up which means you will have to round it down to 20 since the 3 behind the 2 can't round up.

Both the galapagos Islands and the island of naura are on the equator, but the galapagos Islands are at 90.30 degree West whereas the island of naura is at 166.56 degree east. How far is it from galapagos Islands to naura travelling over the pacific ocean along the equator, correct to the nearest km
Answer:
11481.4875 km
Step-by-step explanation:
Given the that :
Galapagos island and Island of Naura are on the equator
Galapagos = 90.30°W
Island of Naura = 166.56°E
Ensuring same bearing is used for both :
Island of Naura = 166.56°E = (360° - 166.56°) = 193.44°W
Hence, we can calculate the difference in the bearing of both locations :
(193.44 - 90.30)°W = 103.14°
Hence the distance between Galapagos and Island of Naura along the equator is :
(Difference in bearing / total bearing) * earth's Circumference
Earth's Circumference = 40,075km
(103.14 / 360) × 40,075
0.2865 × 40,075
= 11481.4875 km

Answer:
22
Step-by-step explanation:
2x+4+x-10=60
3x-6=60
3x=66
x=22
Answer:
[tex]\boxed{\bold{\huge{\boxed{Option \ 4: \ x = 22}}}}[/tex]
Step-by-step explanation:
If AD is a ray inside angle ABC
Then
∠ABD + ∠DBC = ∠ABC
2x + 4 + x - 10 = 60
3x - 6 = 60
Adding 6 to both sides
3x = 60 + 6
3x = 66
Dividing both sides by 3
x = 22

Find the measure of each angle: ∠3 and ∠4 are supplementary. m∠3 = 5x + 22 and m∠4 = 7x + 2.
Answer:
∠3 = 87°∠4 = 93°Step-by-step explanation:
Since ∠3 and ∠4 are supplementary it means the the sum of their angles is equal to 180°
To find the angles add both ∠3 and ∠4 and equate it to 180° solve for x and substitute it into their various expressions
That's
∠3 + ∠4 = 180
5x + 22 + 7x + 2 = 180
12x + 24 = 180°
12x = 180 - 24
12x = 156
Divide both sides by 12
x = 13
So for ∠3
∠3 = 5x + 22
∠3 = 5(13) + 22
= 65 + 22
∠3 = 87°
For ∠4
∠4 = 7x + 2
∠4 = 7(13) + 2
= 91 + 2
∠4 = 93°
We have the answers as
∠3 = 87°∠4 = 93°Hope this helps you
Answer:
[tex] \boxed{ \bold{ \boxed{ \sf{ m \: ∠ \: 3 = 87 °}}}}[/tex]
[tex] \boxed{ \bold{\boxed{ \sf{m \: ∠4 = 93 °}}}}[/tex]
Step-by-step explanation:
We know that the sum of supplementary angle adds up to 180 °
So,
[tex] \sf{5x + 22 + 7x + 2 = 180°}[/tex]
Collect like terms
⇒[tex] \sf{12x + 22 + 2 = 180°}[/tex]
Add the numbers
⇒[tex] \sf{12x + 24 = 180°}[/tex]
Move 24 to right hand side and change it's sign
⇒[tex] \sf{12x = 180 - 24}[/tex]
Subtract 24 from 180
⇒[tex] \sf{12x = 156}[/tex]
Divide both sides of the equation by 12
⇒[tex] \sf{ \frac{12x}{12} = \frac{156}{12} }[/tex]
Calculate
⇒[tex] \sf{x = 13}[/tex]
Value of x = 13
Now, substituting / Replacing the value of x
[tex] \sf{m ∠ 3 = 5x + 22}[/tex]
⇒[tex] \sf{ m \: ∠ \: 3 = 5 \times 13 + 22}[/tex]
⇒[tex] \sf{m \: ∠ \: 3 = 65 + 22}[/tex]
⇒[tex] \sf{ \: m \: ∠ \: 3 = 87}[/tex]
Again,
[tex] \sf{ \: m \: ∠ \: 4 = 7x + 2 }[/tex]
⇒[tex] \sf{m \: ∠ \: 4 = 7 \times 13 + 2}[/tex]
⇒[tex] \sf{ \: m \: ∠ \: 4 \: = 91 + 2 }[/tex]
⇒[tex] \sf{m \: ∠ \: 4 = 93 }[/tex]
m ∠ 3 = 87
m ∠ 4 = 93

The total cost f(x), in dollars, for renting a beach house for x days is shown:
f(x) = 5 + 350x
What does f(5) represent?
Answer:
See below.
Step-by-step explanation:
So we have a function f(x) which is:
[tex]f(x)=5+350x[/tex]
And this represents the total cost (f(x)) in dollars for renting a beach house for x days.
If we use 5 for x:
[tex]f(5)=5+350(5)[/tex]
Multiply:
[tex]f(5)=5+1750=1755[/tex]
This means that the total cost to rent the beach house for 5 days is $1755.
Answer:
The cost of renting the house for 5 days
$1755 for 5 days
Step-by-step explanation:
We are given the function:
f(x) = 5+350x
f(x) represents the total cost in dollars and x represents the days.
If we want to find f(5), we must substitute 5 in for x.
f(5) = 5+350(5)
Multiply 350 and 5.
f(5)= 5+ 1750
Add 5 and 1750.
f(5)= 1755
x represents days and we substituted 5 in for x. Therefore, f(5) represents the cost of renting the beach house for 5 days. f(5) is equal to 1755.
So, It will cost $1755 to rent the beach house for 5 days.

An international company has 29,700 employees in one country. If this represents 29.8% of the company's employees, how many employees does it have in total? Round your answer to the nearest whole number.
Answer:
99, 664
Step-by-step explanation:
Let company has total x employees.
[tex]29.8 \% \: of \: x = 29700 \\ \\ 0.298x = 29700 \\ \\ x = \frac{29700}{0.298} \\ \\ x = 99,664.4295 \\ \\ x \approx \: 99,664 \: [/tex]
Answer: 99,664 employees in total
Step-by-step explanation:
So if 29.8% of the total people is 29,700 people then we could represent that by the equation.
29.8% * x = 29,700 where x is the total people.
0.298 * x = 29,700
0.298x = 29,700
x = 99,664.429
Rounded to the nearest whole number is 99,664

Amy was looking at a table of conversions from meters to kilometers. The table showed that 2 kilometers are equivalent to 2,000 meters, How can she determine how many kilometers are equivalent to 8,000 meters? Explain
Answer:
8 km
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
x 8000 km
--------- = -----------------
2 km 2000 m
Cross-multiplying, we get (2000 m)x = (8000 m)(2 km),
which reduces to x = 8 km
Answer:
Step-by-step explanation:
Since the table showed her that 2 km = 2000m.
To determine, how many km in 2000m, she would divide by 1000.
= 2000 / 1000 = 2 km.
Similarly, for 8000m = 8000 / 1000 = 8 km

Use the First Derivative Test to determine whether the critical point is a local min or max (or neither). (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)
f(x)=(ln(2x)/8x)-7 (x>0)
Also determine the intervals on which the function is increasing or decreasing.
Answer:
Step-by-step explanation:
Let be [tex]f(x) = \frac{1}{8\cdot x}\cdot \ln(2\cdot x) -7[/tex], the first and second derivatives of the function are, respectively:
[tex]f'(x) = \frac{\left(\frac{2}{2\cdot x}\right)\cdot 8\cdot x-8\cdot \ln (2\cdot x) }{64\cdot x^{2}}[/tex]
[tex]f'(x) = \frac{8-8\cdot \ln (2\cdot x)}{64\cdot x^{2}}[/tex]
[tex]f'(x) = \frac{1-\ln(2\cdot x)}{8\cdot x^{2}}[/tex]
[tex]f''(x) = \frac{\left(-\frac{2}{2\cdot x} \right)\cdot (8\cdot x^{2})-[1-\ln(2\cdot x)]\cdot (16\cdot x)}{64\cdot x^{4}}[/tex]
[tex]f''(x) = \frac{-8\cdot x-16\cdot x+16\cdot x\cdot \ln (2\cdot x)}{64\cdot x^{4}}[/tex]
[tex]f''(x) = \frac{-24\cdot x+16\cdot x \cdot \ln (2\cdot x)}{64\cdot x^{4}}[/tex]
[tex]f''(x) = -\frac{3}{8\cdot x^{3}}+\frac{\ln (2\cdot x)}{4\cdot x^{3}}[/tex]
Now, let equalise the first derivative to zero and solve the resulting expression:
[tex]\frac{1-\ln(2\cdot x)}{8\cdot x^{2}} = 0[/tex]
[tex]1-\ln(2\cdot x) = 0[/tex]
[tex]\ln(2\cdot x) = 1[/tex]
[tex]\ln 2 +\ln x = 1[/tex]
[tex]\ln x = 1-\ln 2[/tex]
[tex]x = e^{1-\ln 2}[/tex]
[tex]x = \frac{e}{e^{\ln 2}}[/tex]
[tex]x = \frac{e}{2}[/tex]
[tex]x \approx 1.359[/tex]
This result is evaluated at the second derivative expression:
[tex]f''(1.359) =-\frac{3}{8\cdot (1.359)^{3}}+\frac{\ln [2\cdot (1.359)]}{4\cdot (1.359)^{3}}[/tex]
[tex]f''(1.359)\approx -0.050[/tex]
The critical value leads to a critical maximum and there are two intervals:
[tex](0, 1.359)[/tex] - Increasing
[tex](1.359,+\infty )[/tex] - Decreasing
