Answer:
Step-by-step explanation:
1. 3x=18; you divide each side by 3 because you want to get the x by itself. When you do that, you get x=6.
2. Y+4=11; you subtract each side by 4 because you want to get the y by itself so you do the opposite of that is in front of the +4 (-4). When you do that, you get y=7.
3. W/5=6; you multiply each side by 5 because to get rid of the 5, you multiply(or do the opposite(inverse)) to get the w by itself. That would leave you with w=30.
4. 135=p+21; you subtract each side by 21 to get 114=p.
5. 2m-3=13; the easiest thing to do is to add 3 to both sides to get 2m=16. After that divide both sides by 2 to get m=8.
6. 3/4+a=2 1/4; if it's easier, turn the fractions into a decimal. Subtract both sides by 3/4 to get 1 1/2. a=1 1/2
Answer:
you can use it in architecture and construction
Step-by-step explanation:
say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope. You can use this information to cut properly sized beams to support the roof, or calculate the area of the roof that you would need to shingle. I hope this helps!
Answer:
0.15 = 15%
Step-by-step explanation:
Let's call the recessive allele x, and the dominant allele X.
The homozygotes have the pair xx, and the heterozygotes have the pair Xx.
If two heterozygotes conceive a child, there are four configurations that the child can have:
xx, xX, Xx, XX
the only configuration that allows the child the possibility to have extra fingers and toes is the xx, as this aspect is a recessive trait, so the probability of the child being xx is 25% (1 option between 4 options, all of them with equal probabilities).
If the child is xx, there is a chance of 60% of the child having extra fingers and toes. So, the final probability is:
25% * 60* = 0.25 * 0.6 = 0.15 = 15%
Answer:
6/7
Step-by-step explanation:
Your first step will be to find the slope of Line C. Using the slope formula of 
, the slope of Line C is 
.
If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.
