2.5x7( days in a week) = 17.5 and since its falling it would be negative

Answer:

The correct option is D. -17.5 degrees

Step-by-step explanation:

The daytime temperature in Apple Valley is falling by 2.5 degrees each day

Therefore, Change in the temperature each day = -2.5 degrees

Now, we need to find the net change in the daily temperature after one calendar week

Now, number of days in one calendar week = 7

So, Net change in the daily temperature after one calendar week = Daily change × Number of days in one calendar week

⇒  Net change in the daily temperature after one calendar week = -2.5 × 7

⇒  Net change in the daily temperature after one calendar week = -17.5 degrees

Therefore, The correct option is D. -17.5 degrees

What is the value of x?
Yuliya22 [10]

Answer:

<h2>x = 3</h2>

Step-by-step explanation:

∠QRT and ∠SRT are supplementary angles,

therefore m∠QRT + m∠SRT = 180°.

(45x)° + m∠SRT = 180°            <em>subtract (45x)° from both sides</em>

m∠SRT = 180° - (45x)°

We know: the sum of the measures of the angles of the triangle is equal to 180 °. Therefore we have the equation:

(180 - 45x) + (57 + x) + 25x = 180         <em>combine like terms</em>

(-45x + x + 25x) + (180 + 57) = 180

-19x + 237 = 180             <em>subtract 237 from both sides</em>

-19x = -57             <em>divide both sides by (-19)</em>

x = 3

A rectangular parcel of land has an area of 3,000 ft2. A diagonal between opposite corners is measured to be 10 ft longer than o
Kazeer [188]

Answer:

40 ft × 75 ft

Step-by-step explanation:

Let x be the one side ( in feet ) of the rectangular parcel,

So, the diagonal between opposite corners = ( x + 10 ) feet,

Let y be the other side of the rectangle ( adjacent to side x ),

The area of the rectangle,

A = x × y,

According to the question,

A = 3000 square ft,

\implies xy = 3000\implies y=\frac{3000}{x}

∵ In a rectangle,

D^2=a^2+b^2

Where, a and b are the adjacent side of the rectangle and D is the diagonal,

(x+10)^2 = x^2 + y^2

(x+10)^2 = x^2 + \frac{9000000}{x^2}

x^2(x+10)^2 = x^4 + 9000000

x^2(x^2+100+20x) = x^4 + 9000000

x^4+100x^2 + 20x^3 = x^4 + 9000000

20x^3 + 100x^2 - 9000000=0

x^3 + 5x^2 - 450000 = 0

By graphing the equation,

We found that,

The only real zeros of the equation is at x = 75,

Hence, the one side of the rectangle = 75 ft,

And, second side = \frac{3000}{75} = 40 ft

Hence, the dimension of the land is 40 ft × 75 ft

Answer:

a

Step-by-step explanation:

It begins at the point (0, -1200). 0 tickets sold, $1200 spent.

$5 for a ticket means that slope =5.

(600, 1800) and (0,-1200)

m= (1800-(-1200))/(600-0)=3000/600=5

slope=5

Answer is a.

You have a can that is in the shape of a cylinder. It has a volume of about 1,738 cubic centimeters. The height of the can use 2
Papessa [141]

Answer:

~8.7

Step-by-step explanation:

So we know that the formula for volume is 3.14 * r^2 * h.

So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.

The square root of 75.6 is ~ 8.7
