At noon, a tank contained 10 cm of water. After several hours, it contained 7 cm of water. What is the percent decrease of water in the tank?
Please answer with explanation.
Answer:
10cm - 7cm = 3cm
this 3cm is the decrease in the depth of water, let us find the percentage decrease.
%decrease=(decrease÷original depth) × 100%
%decreas=(3cm÷10cm)×100%
therefore we get 30%
find the exact values of the six trigonometric functions of 0
Complete question is;
Find the exact values of the six trigonometric functions 0 if the terminal side of 0 in standard position contains the points(-5,-4).
Answer:
Sin θ = -4/√41
Cos θ = -5/√41
tan θ = 4/5
Cosec θ = (√41)/-4
Sec θ = (√41)/-5
Cot θ = 5/4
Step-by-step explanation:
Now, we are given the point (-5, -4)
These are x and y points.
They will form a triangle and we know that from pythagoras theorem;
x² + y² = r²
Where r is the distance between the point and the origin
Thus;
r² = (-5)² + (-4)²
r² = 25 + 16
r = √41
So, y is the opposite side of the triangle while x is the adjacent side with r being the hypotenuse.
Thus, the trigonometric ratios are;
Sin θ = opp/hyp = -4/√41
Cos θ = adj/hyp = -5/√41
tan θ = opp/adj = -4/-5 = 4/5
Cosec θ = 1/Sin θ = 1/(-4/√41) = (√41)/-4
Sec θ = 1/cos θ = 1/(-5/√41) = (√41)/-5
Cot θ = 1/tan θ = 1/(4/5) = 5/4

consider the reduction of the rectangle.
A larger rectangle has a length of 18 inches and width of 8 inches. A smaller rectangle has a length of x inches and width of 3 inches.
Write a proportion and then solve to find the missing measure of the reduced rectangle.
What two ratios can be used in the proportion?
What is the value of the missing measure?
Answer:
18/8 = x/3
x = 6.75 inches (length)
Step-by-step explanation:
A larger rectangle has a length of 18 inches and width of 8 inches.
Inches /width = 18/8
So, for a rectangle that has a length of x inches and width of 3 inches the ratio is :
x/3
Solving for x:
18/8 = x/3
18/8 (3) =x
6.75 in= x

By what number must you multiply a quantity in order to increase it by 25% in a single step?
Answer:
5/4
Step-by-step explanation:
Lets suppose a quantity A that has a value of x
A = x
25% of A is = x/4
now adding this 25% to get 25% increase in the original value
A' = x+ x/4
A' = 5x/4
A' = 5*A/4
This means that , in order to increase the value by 25% in a single step we must multiply the the original value by 5/4.

Answer:
14). 2nd quadrant
15). 1st quadrant
Step-by-step explanation:
14).Coordinates of a point → J(-8, -12)
Coordinates of the new point J' after reflection of x-axis will follow the rule,
(x, y) → (x, -y)
Coordinates of J' → (-8, 12)
Therefore, point J' will lie in 2nd quadrant.
15). Coordinates of a point → W(-6, 7)
Rule for the rotation by 90°clockwise about the origin,
(x, y) → (y, -x)
Coordinates of point W → (-6, 7)
Following this rule,
W(-6, 7) → W'(7, 6)
Therefore, point W' will lie in the first quadrant.
The ratio of 6th-grade students to 7th-grade students in a soccer league is 15:10. If there are 100 students in all, how many 7th graders are there? *
Answer:
40 7th grade students.
Step-by-step explanation:
Ok so first we know the total equals 100. In order to divide the number of 6th graders and 7th graders equally, we add 15 and 10 which equals 25. Now, 100 divided 25 equals 4. Boom! We multiply 15 by 4 and that equals 60. This means there are 60 6th graders. We multiply 10 by 4 which means there are 40 7th graders. Now to check if we did it all right we add 60 and 40 which equals 100 STUDENTS IN ALL. This means we did it right. So it asked us for the amount of 7th graders which is 40! Hope this helps.

(c) Pushing Americans to overspend:
This works as the problem, as the irregular spending with credit results in the freezing of the amount.
(d) Causing Americans to go into debt:
It has been a problem that here has been the credit crisis that will result of the credit rise.

1E. The number 2A5A0A2 is divisible by 99. What is the digit A?
We know, a number is divisible by 9 if the sum of digits is also divisible by 9.
Also, since A is an digit, so A is in between 0 to 9.
2+A+5+A+0+A+2 = 3A + 9
3A + 9 should be divisible by 9.
3A + 9 = 9n
A = (9n -9)/3
For n= 1 :
A = 0
For n=2 :
A = 3
For n= 3 :
A = 9
After this A > 9 which is not accepted.
Therefore, the digit A can be 0, 3 and 9 .
Hence, this is the required solution.
The digit A that makes 2A5A0A2 to be divisible by 99 is;
A = 3
From study of divisibility of single digit numbers, it was discovered that a number can be divisible by 9 or a multiple of 9 provided the sum of digits is also divisible by 9.We are given the number 2A5A0A2
A is a single digit and as such will be between 0 and 9.
Thus, using the principle above;
2 + A + 5 + A + 0 + A + 2 = 3A + 9
Applying the principle;3A + 9 must be divisible by 9.
Thus;
3A + 9 = 9x
A = (9x - 9)/3
When x = 1;
A = 0
When x = 2;
A = 3
When x = 3;
A = 9
Since A is a single digit, then it means that x cannot be more than 4 as any value of x more than 4 will yield a value of A that is not a single digit.Now, when we place either the value of 0, 3 or 9 for A into the given number, the only one that yields a number that is divisible by 99 is A = 3

What’s the value of x?
Answer:
x=6
Step-by-step explanation:
We know that <AWV is 90, so we can set up an equation. This equation is 54+3x+18=90, we know this is true because the two smaller angles are complementary. Then to find x simply solve the equation.
First, add like terms
3x+72=90
Then, subtract 72 from both sides
3x=18
Finally, divide both sides by 3
x=6
