A grocer stacks oranges in a four-sided pyramid that is 6 layers high. Solve for the number of oranges in the pile.
Vlada [557]
Each layer contains the square of the layer number.
<span>So,
Let's figure out :
1 squared = 1 </span>
<span>2 squared = 4 </span>
<span>3 squared = 9 </span>
<span>4 squared = 16 </span>
<span>5 squared = 25 
</span>6 squared = 36
<span>Hence,
The total number of oranges in the pile = 1+4+9+16+25+36
                                                               = 91 oranges

Which term describes the example below?A child with no freckles has a mother who has freckles and is heterozygous and a father w
Natali5045456 [20]
It is C as to have freckles you have to have a dominant and recessive gene (can be worked out using a punnett square) as the child has 50% of not having freckles like his dad or 50% having freckles like his mom. 
                     male genes(homozygous recessive)
                     f            f

female    F    Ff           Ff
genes
              f     ff             ff

so ff is not having freckles and being homozygous recessive, or Ff having freckles and being heterozygous.

So the child is heterozygous  so C

A student wants to find out if the amount of bleach has an effect on stain removal.
Step2247 [10]

Answer:

The second option.

Explanation:

We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.

The 2nd option uses different amounts of bleach to clean the same amount of stain.

If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.

It's not an effective way to see if the amount of bleach has an effect on stain removal.
