The water level of a pond falls 3 1/3 feet below its normal level.
Step-by-step explanation:
The water level of a pond is 2 feet below its normal level.
The water level of the pond dropped another 1 1/3 feet.
So the total level dropped is 2 + 1 1/3
= 2 + 4/3
= 6+4/3= 10/3 = 3 1/3 feet below the normal.
Suppose the normal is at zero then the level of the pond is at the end of the summer is 0 - 3 1/3 = - 3 1/3 feet.
If we represent the normal by x then the equation becomes
x- 3 1/3 feet to show the water level at the end of summer.
Or it can also be written as
x - ( 2 + 1 1/3)

Answer:
1.28
is the answer :) since the number after 7 is 5 you round up
Answer: 1.28
The 7 is in the hundredth's place, and since there is a 5 after it, we round up.
For what values of a are the following expressions true?
| a + 5 | = -5 - a
Answer:
not sure if there are more but a=-5
Step-by-step explanation:
|a+5|=-5-a
|-5+5|=-5 - - 5
|-5+5| = -5 + 5
| 0 | = 0
0=0
Answer:
5-5=0+5=5 so the answer is five

Tisha and Dana were both fishing for salmon, and by coincidence, caught the same number of fish this week. Tisha caught salmon in nets that hold 15 15 fish, while Dana caught salmon in nets that hold 18 18 fish. What is the minimum possible number of fish each must have caught?
Answer:
The minimum number of fish each must have caught is 90 fishes
Step-by-step explanation:
The number of fishes Tisha's net can hold = 15
The number of fishes Dana's net can hold = 18
Let the total number of fishes both Tisha and Dana caught = X
15 × A = 18 × B = X
Therefore, X is the lowest common multiple (LCM) of 15 and 18 given as follows;
15 = 3 × 5
18 = 3 × 6
Therefore, the LCM of 18 and 5 = 3 × 5 × 6 = 90
Which gives, the minimum number of fish each must have caught = 90 fishes.

the sum
of the square of two consecutive
odd intergers is
290. Find the integers.
Answer:
11 & 13 or - 13 & - 11
Step-by-step explanation:
Let the integers are a - 1 and a + 1.
Sum of squares = 290
=> (a - 1)² + (a + 1)² = 290
=> a² + 1² - 2a + a² + 1² + 2a = 290
=> 2a² + 2 = 290
=> 2(a² + 1) = 290
=> a² + 1 = 290/2 = 145
=> a² = 145 - 1 = 144
=> a = ± √144 = ± 12
If a = + 12, numbers are
12 - 1 = 11 & 12 + 1 = 13
If a = - 12, numbers are
- 12- 1 = - 13 & - 12 + 1 = - 11

You have been saving nickels, dimes, and quarters in a jar for about a year. You decide to see how much money you've saved up. When you get everything counted it turns out you have 361 total nickels, dimes, and quarters worth a total of $41.45. You think is is odd that you have exactly twice as many dimes as quarters. Find the number of each coin. Number of Nickels: Number of Dimes: Number of Quarters:
Answer:
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78
Step-by-step explanation:
Let
x = number of nickels
y = number of dimes
z = number of quarters
Total worth of the coins = $41.45
Total number of coins = 361
x + y + z = 361 (1)
dime = $0.1,
nickel = $0.05
quarter = $0.25
0.05x + 0.1y + 0.25z = 41.45 (2)
twice as many dimes as quarters.
y = 2z
Substitute y = 2z into (1) and (2)
x + 2z + z = 361
0.05x + 0.1(2z) + 0.25z = 41.45
x + 3z = 361
0.05x + 0.2z + 0.25z = 41.45
x + 3z = 361 (3)
0.05x + 0.45z = 41.45 (4)
Multiply (4) by 20
x + 3z = 361 (3)
x + 9z = 829 (5)
Subtract (3) from (5)
9z - 3z = 829 - 361
6z = 468
Divide both sides by 6
z = 468 / 6
= 78
z= 78
Recall,
y = 2z
= 2(78)
= 156
y = 156
Substitute the value of y and z into
x + y + z = 361
x + 156 + 78 = 361
x + 234 = 361
x = 361 - 234
= 127
x= 127
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78
A restaurant bill is $69. A customer wants to leave a 10% tip. How much should the tip be?
Answer:
$6.90
Step-by-step explanation:
The tip should be $6.90 because you take the 10% tip and turn that into a decimal (0.10) and just multiply that by the bill.
declan deposits $850 into a savings account that pays 3.4% annual interest compounded quarterly. what will be the balance after 5 years?
Answer:
the answer should be $994.5
The balance after 5 year comes out to be $3552.80
What is compound interest ?Compound interest is the interest on savings that is computed using both the original principal and the interest accrued over time. It will accelerate the growth of a sum more quickly than simple interest, which is only applied to the principal sum.
Here,
The declan deposits $850 into a savings account that pays 3.4% annual interest compounded quarterly.
Thus rate= 3.4% and principle amount = 850
Therefore it is compounded quartely,
The balance after year=
[tex]C=Pe^{rt}[/tex]
[tex]C= 850 e^{3.5(5)}\\\\C= 850 e^{17.5}[/tex]
C = 3552.80
Therefore, the balance after a year comes out to be $3552.80
Therefore the balance comes out to be after compounded annually is
$3552.50

Step-by-step explanation:
A triangular park ABC has sides 120m, 80m and 50m (see Fig. 12.7). A
gardener Dhania has to put a fence all around it and also plant grass inside. How
much area does she need to plant? Find the cost of fencing it with barbed wire at the
rate of Rs 20 per metre leaving a space 3m wide for a gate on one side.
pls answer ASAP
The fence would cover the perimeter of the triangle.
The perimeter is the sum of the 3 sides:
120 + 80 + 50 = 250 meters.
There will be a 3 meter space for the gate, so subtract 3:
250 - 3 = 247 meters of fence is needed.
Now multiply the amount of fences needed by the price per meter:
247 x 20 = Rs 4,490
Plot the points A(-4,-6), B(-10, -10), C(-3, -8) on the coordinate axes below. State the coordinates of point D such that A, B, C, and D would form a parallelogram. (Plotting point D is optional.)
Check the picture below.
Coordinates of point D of parallelogram = (3 , -4)
What is parallelogram?A parallelogram is quadrilateral in which opposite angles are equal and opposite sides of the quadrilateral are equal and parallel to each other.
The Diagonals in the parallelogram bisect each other.
Given points
A(-4,-6), B(-10, -10), C(-3, -8)
Let the 4th point D = (x , y)
In a parallelogram, diagonals bisect each other.
midpoint of BD = midpoint of AC
If two points are (x₁ , y₁) and (x₂,y₂)
then midpoint = {(x₁+x₂)/2 , (y₁+y₂)/2}
midpoint of AC = {(-4 + -3)/2 , (-6 + -8)/2}
= {-7/2 , -7}
midpoint of BD = {(-10 + x)/2 , (-10 + y)/2}
Now,
midpoint of BD = midpoint of AC
{-7/2 , -7} = {(-10 + x)/2 , (-10 + y)/2}
Comparing both sides
taking x -coordinate
(-10 + x)/2 = -7/2
Multiplying with 2 on both sides
-10 + x = -7
x = 3
taking y -coordinate
(-10 + y)/2 = -7
Multiplying with 2 on both sides
-10 + y = -14
y = -14 + 10
y = -4
Point D (x , y) = (3, -4)
Hence, (3, -4) are the coordinates of point D of parallelogram.
