Answer:

20 miles

Step-by-step explanation:

I'm not sure if that is exactly how you solve it but

If its

8x+4 as the equation and x is the number of hours run

the total number of miles run should be 20 miles

8(2)+4=20

Answer:

20 miles

Step-by-step explanation:

miles already covered = 4

rate of speed = 8miles / hour

miles to be covered = 8 miles/hr× 2 hr= 16 miles ( because distance is velocity × time)

total miles covered = 16 + 4 = 20 miles.

Answer:

(4,5)

Step-by-step explanation:

The "feasible region" has vertices (0,0), (7,0), (5,4), and (4,5)

P = 5x + 6y

Plug in each vertices in P  and find out which give maximum value

(0,0) => P= 5(0) + 6(0) = 0

(7,0) => P= 5(7) + 6(0) = 35

(5,4) => P= 5(5) + 6(4) = 49

(4,5) => P= 5(4) + 6(5) = 50

We got maximum P=50 for vertex (4,5)

So  the coordinates of the point that has the maximum value is  (4,5)

Two liters of water are poured into an empty vase shaped like an octagonal prism. The base area is 100 square centimeters. What
Molodets [167]

Answer: Height of the water is 20 cm.

Step-by-step explanation:

Since we have given that

Base area = 100 square cm

volume of vase shaped  like an octogonal prism = 2 liters

We need to find the height of water.

and 1 liter = 1000 cm³

2 liters = 2×1000 cm³

As we know the formula for "Volume":

Volume=\text{Base Area}\times height\\\\2\times 1000=100\times height\\\\height=\dfrac{2000}{100}\\\\height=20\ cm

Hence, height of the water is 20 cm.

(12 ÷ 3 + 6) -4 Math help
LekaFEV [45]

Answer:

Well, we have to remember that we must use PEMDAS, or the order of operations, to solve the expression.

<em>Therefore, we must first either divide or multiply anything that is inside of the parentheses. (In this case divide)</em>

12/3=4

(4+6)-4

<em>Now solve what remains in the parentheses.</em>

4+6=10

10-4

<em>Finally, subtract 4 from 10 and get your answer:</em>

An artist wants to frame a square painting with an area of 400 square inches if x is the length of the one side of the painting
tatuchka [14]

There is only one solution to the equation.  A quadratic equation has 2 solutions a positive and a negative, but since we are looking for length, the answer can only be postive.  Area= side^2

              400= x^2

         sqrt(400)=x

          20 inches = x  

The length of one side is 20 inches


check: 20*20 = 400, which is the area of the square painting.
