Answer:
Step-by-step explanation:
- TSA (total surface area) of cuboid= 2(lw+wh+hl)
and the problem said one small cube with 1m width that means it also has 1m length and height
so lets count the cubes for the height, length and width
- Height contains 4 cubes (4m)
- Length contains 4 cubes also (4m)
- Width contains 2 cubes (2m)
Now lets put the givens we got from the figure in the formula of TSA
2*(4*2+4*2+4*4)=64

If seven pencils cost $.84 find the cost of 10 pencils?
Lets solve this!
To solve this question, you need to first divide .84 ÷ 7 which gives you the answer 0.12. Then multiply 0.12 with 10 which gives you the cost of 10 pencils. 0.12 is the cost of only one pencil.
Lets forms this into statements ---
Cost of 7 pencils = $ .84
Cost of 1 pencil = $ 0.12
Cost of 10 pencil equals = .84 ÷ 7 = 0.12
= 0.12 × 10 = 1.2
Cost of 10 pencils is $1.2
Hope I helped (:
Have a great day!
There are a couple of ways you can solve this. You can write it out like
(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)
And pretty much use the foil method
Or you can use the binomial theorem (google it if you dont know)
The solution should be:
(K^7) - 21(k^6) + 189(k^5) - 945(k^4) + 2835(k^3) - 5103(k^2) + 5103k - 2187
Answer:
77%
Step-by-step explanation:
That means that 4 out of 11 people did not have umbrellas
You can write this as a fraction so
4/11 = x/99
Then, multiply both sides by 99 to isolate the variable.
So x is going to equal 99 times 4 divided by 11, which is 36. That means 36 people did not have umbrellas.
