The distance from Nairobi, Kenya to Pretoria, South Africa is 3,969 kilometers. The distance from Cairo, Egypt to Tunis, Tunisia is 2,811 kilometers. Estimate the difference between these two distances by first rounding to the nearest hundred. i need help pleasee

Answers

Answer 1

Answer:

Step-by-step explanation:

3,969 = 4,000 rounded to nearest hundred

2,811=3,000 rounded to nearest hundred

therefore... the difference is 4,000 - 3,000 = 1,000 kilometers

Answer 2

Answer:1,100

Step-by-step explanation:

rounding 3,969 to the nearest hundreds is 4,000 and rounding 2811 to the nearest hundred is 2900. Now you subtract 4000-2900 = 1100.

Answer:

y = 3/2x + 15

Step-by-step explanation:

change f(x) to 'y='

interchange 'x' and 'y' then solve for 'y':

y = 2/3x - 10

x = 2/3y - 10

x+10 = 2/3y

multiply each side by 3/2 to get:

y = 3/2x + 15

the sum of four consecutive even integers is 256. what are the numbers?
no troll ones, please! those who do attempt to will get reported immediately !

Answers

Answer:

61 , 63 , 65 , 67

Step-by-step explanation:

Let the least even number be denoted by x. The sum of the four consecutive even numbers would be:

(x) + (x + 2) + (x + 4) (x + 6) = 256

First, simplify. Combine all like terms:

x + x + x + x + 2 + 4 + 6 = 256

4x + 12 = 256

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 12 from both sides of the equation:

4x + 12 (-12) = 256 (-12)

4x = 256 - 12

4x = 144

Next, divide 4 from both sides of the equation:

(4x)/4 = (144)/4

x = 144/4

x = 61

61 is your first number. Find the next 3 consecutive numbers:

x = 61

x + 2 = 63

x + 4 = 65

x + 6 = 67

Check:

61 + 63 + 65 + 67 = 256

256 = 256

A survey result shows that cell phone usage among teenagers rose from 63% in 2006 to 71% in 2008.
Of the following choices, which statement about cell phone use among teenagers is true?
a. Cell phone usage rose by 11.2 percentage points.
b. Cell phone usage rose by 12.7 percentage points.
c. Cell phone usage rose by 12.7%.
d. Cell phone usage rose by 8%.

Answers

Answer:

d. Cell phone usage rose by 8%.

Explanation:

71 - 63 = 8

The statement that is true about percentage increase in cell phone use among teenagers is; c. Cell phone usage rose by 12.7%.

How to calculate percentage increase?

We are given;

Percentage of teenagers using cell phone in 2006 = 63%

Percentage of teenagers using cell phone in 2008 = 71%

Thus;

Percentage increase = (71% - 63%)/63%

Percentage increase = 12.7%

4x+8y=16

6x-8y=4

________

x=2

Plug x=2 into one of the original equations to get the value of "y":

Answer:

Equation: 4x + 30 + 2x + 6 = 180

Answer: x = 24

Step-by-step explanation:

The sum of the measures of supplementary angles is 180 deg.

Equation:

4x + 30 + 2x + 6 = 180

Solution:

4x + 30 + 2x + 6 = 180

Add like terms on the left side.

6x + 36 = 180

Subtract 36 from both sides.

6x = 144

x = 24

Answer:

X=24

Step-by-step explanation:

Supplementary angles = 180°

4x+30+2x+6=180

Combine like terms> 4x+2x=6x

Add: 30+6=36

6x+36=180.

Subtract 36 on both sides. > 36-36=0. 180-36=144.

Drop what you have left> 6x   144

Divide by 6. > 6/6= 1. 144/6=24.

The area of the circle in terms of π is:

9/64 π in^2

Step-by-step explanation:

To find the area of that circle, you can use the equation:

Area of a circle = [tex]\pi * \frac{D^{2}}{4}[/tex]

Where:

D = Diameter (3/4 in)

Now, we can replace the given measurement in the equation:

Area of a circle = [tex]\pi * \frac{(\frac{3}{4}in) ^{2}}{4}[/tex]Area of a circle = [tex]\pi * \frac{\frac{9}{16}in ^{2}}{4}[/tex]Area of a circle = [tex]\pi * \frac{9}{64} in^{2}[/tex]

That result is the same that to write:

Area of a circle = [tex]\frac{9}{64}\pi in^{2}[/tex]

By this reason, the result is 9/64 π in^2, giving the result in terms of π.
