About 71% of Earth’s surface is covered in water.
Question 1
Part A
If Earth's surface area is about 196,900,000 square miles, about how many square miles are covered in water?
Enter the correct answer in the box.
Part B
About what percent of Earth’s surface is not covered in water? How many square miles is this?
Enter the correct answers in the boxes.
Answer:
A. 139,799,000 square miles
B. 57,101,000 square miles
Step-by-step explanation:
71% ÷ 100 = 0.71
0.71 x 196,900,000 = 139,799,000
100 - 71 = 29
29 ÷ 100 = 0.29
0.29 x 196,900,000 = 57,101,000
another way; knowledge of A
196,900,000 - 139,799,000
= 57,101,000
Mathematically, why am i so uneducated?
Answer:
I know this is most likely a joke but I'll answer anyways :)
"Mathematically" you might have poor education whether it's bad teachers, bad school, or maybe you're just not working hard enough. Maybe you are educated and you're just comparing yourself against smarter people which might make you seem not very educated. Or maybe you're secretly a super genius prodigy and you're just too lazy too show it. Who knows...

The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Step-by-step explanation:
Let the athletes be 3x and 2x.
Now, By the question we get,
(3x-12)/(2x+12) = 5/4
or, 12x-48= 10x+60
or, 2x = 108
so, x = 54
now
3x= 3×54= 162
2x = 2×54=108
The number of athletes were 162 in first team and 108 in second team originally.
x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )
y ----------------------------------------second------------------( y ∈ Nˣ )
The ratio of athletes in the two teams is 3:2
⇒ [tex]\frac{x}{y} =\frac{3}{2}[/tex] (1)
After 12 athletes move from first team to second, the ratio is 5:4
⇒ [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]
So: The first team originally has 162 numbers and the second team originally has 108 numbers
ok done. Thank to me :>

At the intersection of lines p, r, and s, clockwise from top left, the angles are blank, 93 degrees, blank, A, C, B. At the intersection of lines q and s, the angles are blank, 60 degrees, blank, blank. At the intersection of r and q, the angles are 27 degrees, blank, blank, blank. Complete the statements based on the diagram. mAngleA = 27° because it is to the 27° angle. The measure of Angle can be found because it is a vertical angle to the 93° angle. The sum of the measures of angles A, B, and C is degrees.

A scuba diver descends in the water at a rate of 2312 feet per minute for 2.6 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 28 feet per minute for 2 minutes.
What is the scuba diver's position relative to sea level after the 4.6 minutes?
Enter your answer as a decimal in the box.
ft
2312 FPM for 2.6 minutes
2312 x 2.6 = 6011.2
28 FPM for 2 minutes
28 x 2 = 56
6011.2 descend
55 ascend
0-6011.2 = -6011.2
ans + 56 = -5955.2
:)
Answer:
Descends: 2,312 x 2.6 = - 6,011 (when rounding otherwise known as - 6,011.2, this number is negative because he is descending)
Ascends: 28 x 2 = 56
- 6,011 + 56 = -5,955 (in 4.6 minutes)
Step-by-step explanation:
I believe this is the correct answer, I'm not 100% sure though. Please tell me if I'm wrong. Have a wonderful rest of your day or night! ~ ^w^ ~
when keisha installed a fence along the 200 feet perimeter of her rectangular back yard she left and opening for GATE in diagram below she used X to represent the length of the gate
Perimeter of her rectangular back yard is: 200 ft
⇒ 2(30 + 60 + x) = 200
⇒ 30 + 60 + x = 200/2 = 100
⇒ 90 + x = 100
⇒ x = 100 - 90 = 10

You go to a restaurant and order $137.61 worth of food. You decide to tip the waiter 18%. You also have to pay a tax of 6.5% on the original bill. What is the final cost of the meal?
Answer:
$171.31
Step-by-step explanation:
The final cost of meal is $171.35
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
price of food = $137 . 61
Tip = 18%
tax = 6.5%
Now, price after giving tip
=137.61 x 0.18
= 24.7698
and, after tax
=137.61 x 0.065
=8.94465
Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35

The Ramirez family has a circular garden with a diameter of 22 feet. They cover the garden with mulch. The cost of mulch is $1.25 per square foot. To the nearest dollar, how much will it cost to cover the garden with mulch. Show your work.
A.$380 B. $475
C. $1.520 D. 1.900
Answer:
b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has a radius of 11 feet
the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380
Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y + 7 = (-14/17)(x - 8)
Step-by-step explanation:
We want the equation of this line in the point-slope form y - k = m(x - h).
We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above. Then the other point is represented by (x, y) in the point slope form shown above:
Let (h, k) be 8, -7) and let (x, y) be (-9, 7). Then, y - k = m(x - h) becomes:
7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17
The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).
Another way to get this result would be to find m in the usual way:
rise 14
m = ------------- = --------- = -14/17 (same as before).

A farmer wants to increase the area of his rectangular pen but keep the pen a rectangular shape. He decides to add 2 1/2 feet of fencing to the width of the pen, but the length will remain 9 1/4 feet. The new area will be 108 3/4 square feet.
Which equation can be used to determine the original width, w, of the pen?
9 1/4(w+2 1/2)=108 3/4
9 1/4w+2 1/2=108 3/4
2 1/2(w+9 1/4)=108 3/4
2 1/2w+9 1/4=108 3/4

what’s the area of this figure? lol i have no idea helppp
Answer:
285
Step-by-step explanation:
For the top section, we can portion out 20 x 8 = 160.
Next, directly in the middle is a 5 x 5 square = 25.
Finally, we have a right triangle with dimensions 10 x 20 so the area would be 10 x 20 / 2 = 100.
160 + 25 + 100 = 285.

8.067 ; hundredths Round each decimal to the place indicated.
Answer:
8.06
Step-by-step explanation:
Decimals go in the order 10ths hundredths thousandths ten thousandths and so on. In rounding any decimal, one number gets added to the left if the number is 5 or over and the number is discarded if it is lower than 5.
for example if the number was 1.2345 5 would make 4 5 1.235 then 5woould make 3 4 1.24 but if you want to round to a smaller number the other numbers would not go up the numbers would just be discarded.
