HELP PLS ASAP -5 = 5/12a pls evaluate

Setler79 [48]

Answer:

a = -12

Remember that when a variable is times with a number, you divide the number on both sides.

When a variable is divided by a number, you multiply the number on both sides.

Hope this helps you. Thank you !!

A water trough is 9 m long and has a cross-section in the shape of an isosceles trapezoid that is 20 cm wide at the bottom, 70 c

ella [17]

Answer:

dv = surface area * dh

dv/dt = surface area * dh/dt

width at surface = 40 + (80-40)(30/40)

= 40 + 30 = 70 cm = 0.70 m

surface area = 9 * .7 = 6.3 m^2

.3 m^3/min = 6.3 m^2 * dh/dt

and

dh/dt = .047 meters/min or 4.7 cm/min

How can I find the surface area of a right cone with a radius of 6 and slant height of 16

VMariaS [17]

First, you have to calculate the height.
Pythagorean Theorem:
a^2+b^2=c^2
Slant height=c^2
Radius=b^2
So, a^2+6^2=16^2
a^2+36=256
a^2=220
a=14.832397
Surface Area = πr(r+ square root of h^2+r^2)

Surface Area is approximately 414.69

See the diagram below, which is not drawn to scale:

Vanyuwa [196]

Answer:

700.4 cm

Step-by-step explanation:

Use a proportion.

Let x be the vertical distance for the 700 cm pipe.

1 cm is to 30 cm as x cm is to 700 cm

1/30 = x/700

30x = 1 * 700

30x = 700

3x = 70

x = 70/3

Now we need l. We have a right triangle with legs measuring 70/3 cm and 700 cm, and we are looking for the hypotenuse l.

a^2 + b^2 = c^2

(70/3)^2 + 700^2 = c^2

c^2 = 4900/9 + 490000

c = 700.4

l = 700.4 cm

A triangle has a perimeter of 10a + 3b +12 and has sides of length 3a+8 and 5+b, what is the length of the third side?

makvit [3.9K]

Answer:

The third side of the triangle is (7a + 2b -1).

Step-by-step explanation:

The length of the first side = (3a +8)

The length of the second side = (5 +b)

Let us assume the third side = m

The perimeter of the triangle = SUM OF ALL 3 SIDES

⇒ (10a + 3b +12) = (3a +8) + (5 +b) + m

or, (10a + 3b +12) = 3a + b + 13 + m

or, m = (10a + 3b +12) -(3a + b + 13)

= 10 a + 3b + 12 - 3a - b - 13

= 7a + 2b -1 = ( 10 - 3a) + (3b -b) + 12 -13

or, m = (7a + 2b -1)

Hence, the third side of the triangle is (7a + 2b -1).
