Answer:

-4

Step-by-step explanation:

The slope of this graph is the gradient. As it is sloping downwards the gradient will be negative, so either -4 or -14.

The gradient can be found by using the equation gradient=rise/run

The line passes through (-2, 5) and (0,-3).

This means the run (x-direction) is -2-0= -2 and the rise (y-direction) is

5 - (-3) = 5+3 = 8

Therefore the gradient is equal to 8/-2 = -4

A local hamburger shop sold a combined total of 437 hamburger and cheeseburgers on Thursday. There were 63 fewer cheeseburgers s

trasher [3.6K]

Let h represent hamburgers and c represent cheeseburgers. We can set up an equation:

h + c = 437

h + (h - 63) = 437

h + (h - 63 + 63) = 437 + 63

h + h = 500

2h = 500

2h / 2 = h

500 / 2 = 250

h = 250

250 hamburgers were sold.

To find how many cheeseburgers were sold, we subtract 250 - 63:

250 - 63 = 187

187 cheeseburgers were sold.

187 + 250 = 437

250 hamburgers and 187 cheeseburgers were sold on Thursday.

A water sprinkler has a range of 5 meters as shown. The jet of water from the sprinkler sweeps out at an angle of 85° as the noz

damaskus [11]

Take a look at the attachment below. It may help!

With this sector we can create a proportion to find the area watered by the sprinkler. 85 degrees over a total 360 degrees would be simplified to the following -

17 / 72 = ( About ) 4.235

Thus, we can calculate the area of the circle with a range of 5 meters radius, and divide by about 4.235 to receive the area watered by the sprinkler, or the area of the sector -

$Area( Full Circle ) = \pi r^2,\\Area( Full Circle ) = \pi * ( 5 )^2,\\Area( Full Circle ) = 25\pi,\\\\Area( Full Circle ) = ( About ) 78.5$

__________________________

$Area( Watered By Sprinkler ) / Area( Sector ) = 78.5 / 4.235,\\Area( Watered By Sprinkler ) / Area( Sector ) = ( About ) 18.5$

The solution should be about 18.5 meters^2

Is one for greater than listen or equal to 0.4

rjkz [21]

Order 3/8, 3/7, and 3/9 from least to greatest without writing equivalent fractions with a common denominator explain your Strategy

3/9 3/8 3/7

The greater the denominator, the smaller the pieces are. Thus, numbers with equivalent numerators but smaller denominators will be larger than those with larger denominators.

Is 0.7 greater than less than equal to 7/9

Less than. 7/9 is 0.77777....

Image of parabola with a maximum value at (1, 9), y-intercept at (0, 8) and x-intercepts at (2, 0) and (4, 0).

natka813 [3]

Answer:

(a) 4 seconds

Step-by-step explanation:

The given point (4, 0) on the parabola tells you the answer to the question: the coin was in the air 4 seconds before its height is 0. It is no longer in the air at that point.

Additional comment

In order to match the rest of the problem statement, the first given x-intercept must be (-2, 0).

Find x. Assume that segments that appear tangent are tangent.

kipiarov [429]

Assuming that CB is tangent, this is just a right triangle with a hypotenuse of 20 and a side of 12 so by the Pythagorean Theorem:

20^2=12^2+x^2

400=144+x^2

x^2=400-144

x^2=256

x=16
