Answer:

rectangular prism = cuboid

total surface area of a cuboid (tsa) = 2(lb+bh+hl)

l=length = 3cm

b=breadth = 6cm

h=height = 5cm

tsa = 2( 3*6 + 6*5 + 5*3 )

2( 18 + 30 + 15 )

2 * 63

= 126 $cm^{2}$

hope this answer helps you.....

Seven less than the product of a number n and 1/6 is no more than 94

antiseptic1488 [7]

Answer:

n ≤ 606

Step-by-step explanation:

Seven less than the product of a number n and 1/6 is no more than 94, translating:

n*1/6 - 7 ≤ 94

Solving for n:

n/6 ≤ 94 + 7
n/6 ≤ 101
n ≤ 101*6
n ≤ 606

Cerrena [4.2K]

Answer:

See below ~

Step-by-step explanation:

Table 1

⇒ Side length : Perimeter = 1 : 4

⇒ Perimeter : Side length = 4 : 1

Table 2

⇒ Radius : Diameter = 1 : 2

⇒ Diameter : Radius = 2 : 1

Table 3

⇒ Number of people : Number of tables = 5 : 1

⇒ Number of tables : Number of people = 1 : 5

What is the value of r? Round your final answer to the nearest whole number.

vaieri [72.5K]

Answer:

r = 13

Step-by-step explanation:

Hypotenuse is the side opposite to 90 degree angle, so hypotenuse is r.

Also, with respect to the angle given, the side "12" is the opposite.

So we have opposite side to angle and we need hypotenuse. Which trigonometric ratio related opposite with hypotenuse? It is SINE.

So we can write:

$Sin(67.4)=\frac{Opposite}{Hypotenuse}=\frac{12}{r}\\rSin(67.4)=12\\r=\frac{12}{Sin(67.4)}\\r=12.99$

Rounded to nearest whole number, r = 13

ASAP: Hose A fills a water truck at the constant rate of 60 gallons every 15 minutes. Hose B fills a water truck at a constant r

jeka57 [31]

Answer:

Step-by-step explanation:

Hose A:

60 gallons every 15 minutes mean:

60 / 15 = 4 gallons per minute

For Hose B:

If we put x = 1, we can find gallons (y) per minute (x)

y = 3 x

y = 3(1)

y = 3

That means 3 gallons per minute

Thus, the rate of Hose A is 1 gallon per minute more than the rate of Hose B. Option C is correct.

Answer:

The surface area of the prism is 276 in.²

If you are also looking for the volume of the prism, it is 280.

Step-by-step explanation:

It's hard to find the surface area and the volume of the prism if you're just looking at the net of the 3D shape. There are some unnecessary measurements that will definitely throw you off. I drew a sample prism so it's easier to solve. Check the linked image.

The formula in finding the surface area of a prism is SA = 2(wl + hl + hw), where w is for width, l is for length, and h is for height. The point of all of these calculations is to find the area of 3 different faces of the prism and then you add up all of the areas and multiply the sum by 2 to give you the surface area. Looks a lot but it's worth getting the answer right.

The formula in finding the volume of the prism is V = w * h * l, where w is for width, h is for height, and l is for length. Simple multiplication of 3 different sides and you'll get the volume. I hope this helps and if I am wrong please let me know! :D
