Approximately 71% of the Earth’s surface is water. The total surface area of the Earth is approximately 5.1 x 1014 m2. How many square meters of the Earth’s surface is not water?
Answer:
1.5 × 10^14 m²
Step-by-step explanation:
71% of the surface is covered with water.
The total surface of the Earth is 100% of the surface.
100% - 71% = 29%
29% of the surface is not covered with water.
29% of 5.1 × 10^14 m² =
= 0.29 × 5.1 × 10^14 m²
= 1.479 × 10^14 m²
= 1.5 × 10^14 m²

Answer:
d) 189.3 in²
Step-by-step explanation:
Area of rectangle is,
→ w × l
→ 10 × 15
→ 150 in²
Area of semi circle is,
→ (1/2)πr²
→ (1/2) × 3.14 × (5)²
→ 1.57 × 25
→ 39.3 in²
Now the total area will be,
→ 150 + 39
→ 189.3 in²
Thus, total area is 189.3 in².

Group of answer choices
1. 13
2. 18
3. 8
4. 11
Answer:
8
Step-by-step explanation:
Because we multiply 4 by both sides
2 times 4 is 8 for girls
4 times 3 is 12 for boys
So it asked for girls and 4 times 2 is 8
So the answer is 8
8 women are in the class.

The value of the car zero km is given by the expression x = 60000.
LET ME EXPLAIN SOMETHING:
An algebraic expression is one that has several operations between numbers and letters (unknowns): addition, multiplication, subtraction, division, potentiation, rooting, etc.
LET'S GO TO THE SOLUTION:
Let x be the initial value of the car, we know that it depreciates 10% when leaving the agency and another 5% after one year. If the value of this car is $51,300.00 after 1 year, we will have to:
When you leave the agency, your value decreases by 10%:
x·(100% - 10)% = 90% of x = 0.9xAfter a year, its value decreases by 5%:
0.9x·(100% - 5)% = 95% of 0.9x = 0.855x0.855x = 51300
x = 60000

If angle 1 is 25 degrees in the parallelogram pictured above, what is angle 2
if q is 1x+ 10 and AC is 7x+8 what is the length of AC? Round your answer to the nearest hundredth
Applying the properties of a parallelogram:
1. Length of AC = 24.8 units
2. x = 1
What are the Properties of a Parallelogram?Some properties of parallelogram we need to recall in order to solve the problem given are:
They have two pair of sides that are parallel to each other and also of the same length.They have two diagonals that bisect each other into equal halves.1. q = 1x + 10
AC = 7x + 8
Therefore:
q = 1/2(AC) [based on the property of a parallelogram]
Substitute
x + 10 = 1/2(7x + 8)
Solve for x
2(x + 10) = 7x + 8
2x + 20 = 7x + 8
2x - 7x = -20 + 8
-5x = -12
x = -12/-5
x = 2.4
Length of AC = 7x + 8 = 7(2.4) + 8
Length of AC = 24.8 units
2. x + 8 = 7x + 2 [based on the property of a parallelogram]
x - 7x = -8 + 2
-6x = -6
-6x/-6 = -6/-6
x = 1

Answer:
Option: A is the correct answer.
Step-by-step explanation:
Clearly from the graph we could observe that the graph is a decay exponential function as the graph of the function is decreasing with the increasing value of x.
Hence, the rate has to be less than 1.
So, option: B and D are ruled out as they represent a growth exponential function.
Also from the graph given in the question we could observe that when x=0 the value of y is:
