Evaluate: 30 - 12÷3×2 =

Mathematics
1 answer:
lara [203]3 years ago

Answer:

22

Step-by-step explanation:

We can use the order of operations (PEMDAS), to solve this equation.

We must first multiply and divide, and order. This means we divide 12 by 3 and get 4, then multiply that by 2 and get 8. (30-12÷3×2,30-4×2,30-8). Now we just subtract 8 from 30 and get 22 as our answer.

Arwen uses an eye dropper that produces drops that has a volume of 1/8 milliliter to fill 30 milliliter test tube. How many drop
oksian1 [2.3K]
To answer this question, you need to know how many drops go into atheism test tube.

Each drop is 1/8 milliliter. The test tube is 30 milliliter.

So, divide 30 by 1/8 to see how many times 1/8 goes into 30.

30 divided by 1/8 = 30 times 8 = 240

It takes 240 drops (that's a lot!) to fill up the test tube.

Hope this helps!

Calculate the snow load for the low-slop (flat) roof. For this structure, we will use the following coefficients. Cs = 1.0 Ce =
CaHeK987 [17]

Answer:
The width of member is as follows:
b = 3 ft

b = 3 × 12 in.

b= 36 in.
The depth of member is as follows:

d = 8 ft

d = 8 × 12 in.

d=96 in.
Since the structure used is Douglas fir-Larch lumber of size 3 × 8 size. Hence, tensile strength, f =1000 psi
Calculate the net area of the member as follows:
A = (b - ∅) × d

A= (36 - 7/8) × 96
A = 3372in^{2}
Calculate the maximum axial tensile load by ASD method as follows:
P = f × A

P = 1000 x 3372

P = 3372000 lbs  
P = 3372 kips

Monte performs an experiment using 2 identical graduated cylinders, each with a radius of 2 centimeters. The volume of the liqui
elena55 [62]
Volume of a cylinder is h x r^2 x pi

You have the volume and radius of each one, so taking 188.4=(2)^2 x 3.14 x h1, you can solve this equation for the height h1. Likewise, for the other graduated cylinder you take 314=2^2 x 3.14 x h2, and then solve for h2.

To get the difference in heights, just take h2-h1 after solving the equations for h2 and h1
