If the area of the base of a rectangular prism is 35 square feet and the volume is 175 cubic feet, what is the height of the pri
Elis [28]

Answer:

5 ft

Step-by-step explanation:

area = L * W * H

35    =  L * W

Volume = (L *W) * H

since we have already found that L * W is already 35

175 = 35 * H

Divide by 35  on both sides to get H

175/35 = 5

answer = 5 ft

Round 7,207 to the nearest thousand
Anna71 [15]

7, 207

7 = thousands place

2 = hundreds place

0 = tens place

7 = ones place

You want to round to the nearest thousand, the 7 all the way on the left is the number you're looking for.

Next, the number to the right of it, is it higher than 5 or lower than 5?

Since the number on the right is lower than 5 (it's a 2 - in the hundred's place), you round down to 0. If it was higher than 5, you round the 7 in the thousands place to an 8.


<h2>7.207 rounded to the nearest thousand is 7,000</h2>

The point P(x, y) lies on the terminal side of an angle mc014-1.jpg = –60° in standard position. What are the signs of the value
madreJ [45]
<span>The sign value for x is positive and for y is negative. In standard position, the x point is at the origin, so the value will be 0. The terminal side is the line that moves to create the angle. At -60 degrees, the terminal side will be in the minus side of the y axis.</span>

NO LINKS!! Please help me with this problem​
Vera_Pavlovna [14]

Information : The given hyperbola is a horizontal hylerbola with its centre (3 , -5) and one of its focus at (9 , -5) and vertex at (7 , -5) and as we can see that the focus and vertex have same y - coordinates, it must have its Transverse axis on line y = - 5.

Now,

it's vertex is given, I.e (7 , -5)

so, length of semi transverse axis will be equal to distance of vertex from centre, i.e

  • a = 7 - 3 = 4 units

Now, it's focus can be represented as ;

\qquad \sf  \dashrightarrow \: (3 + ae,  - 5 )

so,

  • ae + 3 = 9

and we know, a = 4

\qquad \sf  \dashrightarrow \: 4e + 3 = 9

\qquad \sf  \dashrightarrow \: 4e = 6

\qquad \sf  \dashrightarrow \: e =  \cfrac{3}{2}

Now, let's find the measure of semi - conjugate axis (b)

\qquad \sf  \dashrightarrow \:  {b}^{2}  =  {a}^{2} ( {e}^{2}  - 1)

\qquad \sf  \dashrightarrow \:  {b}^{2}  = 16( \frac{9}{4}  - 1)

\qquad \sf  \dashrightarrow \:  {b}^{2}  = 16( \frac{9 - 4}{4}  )

\qquad \sf  \dashrightarrow \:  {b}^{2}  = 16( \frac{5}{4}  )

\qquad \sf  \dashrightarrow \:  {b}^{2}  = 20

\qquad \sf  \dashrightarrow \: b =   \sqrt{20}

So, it's time to write the equation of hyperbola, as we already have the values of a and b ~

\qquad \sf  \dashrightarrow \:  \cfrac{ {(x - h)}^{2} }{ {a}^{2} }  -  \cfrac{( {y  - k)}^{2} }{ {b}^{2} }  = 1

[ plug in the values, and h = x - coordinate of centre, and k = y - coordinate of centre ]

\qquad \sf  \dashrightarrow \:  \cfrac{ ({x-3)}^{2} }{ {16}^{} }  -  \dfrac{ {(y+5)}^{2} }{ { {20} }^{} }  = 1

Pls help! will give brainlist!
Rainbow [258]

Answer:

C) The solution for the system of equations

Step-by-step explanation:

Point (3, 120) is where both lines intercept!

Basically, (3, 120) is where both equations are equal to each other.

(120 = 20(3) + 60) = (120 = 40(3))

We can test it!

120 = 20(3) + 60

120 = 60 + 60

120 (Correct)

120 = 40(3)

120 = 120 (Correct)
