Suppose that the water level of a river is 50 feet and that it is receding at a rate of 0.75 foot
per day. Write an equation for the water level,, after days. In how many days will the water
level be 30 feet?

Answers

Answer 1
Y=-0.75x+50

Now put in 30 for y:
30=-0.75x+50
-20=-0.75x
X=26.6666
So in 26/27 days

Step-by-step explanation:

The answer to this question would be A. But why? First you see the point on (-2,3) and than it asks for you to rotate the point 90 degrees. Now, this is where things get tricky because it doesn’t specifically ask for any sort of rotation and in seeing this we assume they mean clock wise because they didn’t state otherwise. So after rotating the point 90 clockwise we land at the point (2,3). I hope this helps!

Answers

Answer:

Surface Area of the Cylinder is 1156.11

Step-by-step explanation:

To find the Surface Area of a Cylinder, the equation given is  A = 2πrh+2πr2

Given the radius and height of the cylinder, we plug those numbers into the equation to get;

A = 2π(8)(15)+2π(8)2

= 1156.11

Answer:  

1155.52 cm²

Step-by-step explanation:

SA = LSA (Pb x h) + 2B                  

- r = 8 cm, h = 15, π (pi) = 3.14

Lateral Surface Area (LSA) = Pb (Perimeter of base) x h (height)

8 x 2 = 16 x 15 = 240 x 3.14 = 753.6

Area of the Base x 2 = πr² x 2

8² x 3.14 = 64 x 3.14 = 200.96 x 2 = 401.92

753.6 + 401.92 = 1155.52

-6x - 3 = 21

Answers

Answer:

x = -4

Step-by-step explanation:

−6 − 3 = 21

−6 − 3 + 3 = 21 + 3

= −4

The solution to the equation -6x - 3 = 21 is x = -4.

We must separate the variable x on one side of the equation in order to determine the answer to the equation -6x - 3 = 21.

Here's how to accomplish that:

Step 1: Add 3 to both sides of the equation to start moving the constant term (in this example, -3), which is the first step:

-6x - 3 + 3 = 21 + 3

To put it simply, we have:

-6x = 24

Step 2: Subtract -6 from both sides of the equation to find the value of x:

(-6x) / -6 = 24 / -6

This can be written as x = -4.

Consequently, x = -4 is the answer.

JL has endpoints J(8,10) and L(20,5). Point K has coordinates (13,9). What is the length of JL?

Answers

The length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.

According to the question, we are required to determine the length of line JL.

However, the coordinates of the end points of line JL are given as;

Point J; (8,10)

Point L; (20,5).

The length of line JL is given by Pythagoras theorem as;

JL = √(20-8)² + (5-10)²

JL = √ 12² + (-5)²

JL = √ 144 + 25

JL = √169

JL = 13.

Therefore, the length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.

This had a devastating impact on the Colville and Spokane tribes, whose traditions and cultural ties to the land, water, and wildlife were disrupted. By 1937, the dam's slow rise from the riverbed had completely halted salmon, steelhead, and other species from reaching important tribal fishing sites like Kettle Falls on the Columbia River, and Little Falls on the Spokane River. Tribal members could no longer fish for this most valued commodity on which they depended. The annual salmon runs that anchored the tribes' yearly schedules, including the timing of their most important ceremonies, were gone. In addition, land was cleared for the dam site and reservoir. This impacted more than 3,000 homesteaders and Native Americans, who were displaced during the early design and construction phase. Tens of thousands of acres were cleared at a cost of over $10 million-- prime bottom land where Native Americans and pioneers had been living, hunting, and fishing for generations. Both the Colville and Spokane tribes were asked to relocate the remains of their ancestors by moving them to new cemeteries on higher ground. please answer, right now NEPTUNE Number of days to orbit the sun:Distance around the sun: Simplify.
