First you divide the L block into two separate rectangles. Then find the area of the two figures. Then add the products of the two rectangles and add the unit of measurement cubed.

First break the L into two rectangular prisms and then find the volume for each prism. Then add those two volumes together to get the L.

Determine the volume of the rectangular prism.<br>

Flauer [41]

Answer:

Step-by-step explanation:

We know the formula for a rectangular prism is length × width × height

We also know all the sides so we can rewrite the formula replacing variables.

The length is 8, the width is 2 $\frac{1}{2}$ and the height is 2 $\frac{1}{2}$

8 × 2 $\frac{1}{2}$ × 2 $\frac{1}{2}$

Multiply which ever way is easy for you. I am just multiplying from left to right.

8 × 2 $\frac{1}{2}$ = 20

20 × 2 $\frac{1}{2}$ = 50

Now we get 50. Before we put our answer as 50, there are two more steps.

First we need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

<u>50 ft³ is our final answer</u>

6x+4y=42 -3x+3y=-6 by elimination

creativ13 [48]

Answer:

x=5, y=2

Step-by-step explanation:

To solve this system, we need to find x and y. First, let's find x. In the first equation (6x+4y=42), subtract 4y on both sides to isolate 6x. This will result in 6x=42-4y. Divide by 6 on both sides to isolate x and get x=7- $\frac{2}{3}$ y. Now we know what x equals. Go to the second equation ad plug this into it. So instead of -3x+3y=-6, you'll have -3(7- $\frac{2}{3}$ y)+3y=-6. Use the distributive property to get -21+2y+3y=-6. Add 2y and 3y to get -21+5y=-6. Add 21 to both sides to isolate 5y and get 5y=15. Divide by 5 on both sides to isolate y and get y=3. Now that we know that y=3, we can plug this back into the equation that was bolded above so that we can find x, so we'll have x=7- $\frac{2}{3}$ (3) since y=3, and we'll get x=7- $\frac{6}{3}$ , or x=7-2, or x=5.

x=5

y=2

The atmospheric pressure P on a balloon or in aircraft decreases with increasing height . This pressure measured in Millimeters

Vesnalui [34]

Answer:

(A) 5.47 km

(B) 1.38 km

Step-by-step explanation:

The relationship between Pressure (mmHg) and Height (km) is given by the equation below:

p =760 e⁻ 0.145h----------------------------------------------------- (1)

(a) The height of the aircraft can be calculated by making 'h' the subject of equation (1)

In (p/760) = -0.145 h

h = -In (p/760) /0.145

h= In (760/p)/ 0.145------------------------------------------------- (2)

For the aircraft, p =344 mmHg; substituting into (2)

h = In (760/344)/0.145

= 0.7926/0.145

= 5.4662 km

≈ 5.47 km

(b) p= 622 mmHg at the mountain top. Substituting into equation (2) we have:

h = In (760/622)/0.145

= 0.2003 / 0.145

= 1.3813 km

≈ 1.38 km
