Answer:
The number is 5
Step-by-step explanation:
First of all we have to convert the given scenario in mathematical or algebraic expression.
Let x be the number
Then according to given statement, the equation will be:
"Three times a certain number"
"is added to 5"
"the result is 20"
Using Subtraction property of Equality
Using division property of equality
Hence,
The number is 5
Answer:
The transformation,
Step-by-step explanation:
H to Z to K
Answer:
I'll do the first one as an example. The answer of the first one is 6.
Step-by-step explanation:
In the first example, they multiplied the number by 2 to get a common denominator for the two fractions so you can easily add. So, the first box will come 10 (5 times 2) and the second box will become 2 (1 times 2). Then simply add the fractions. The sum of the first question is 2. Because 2 10/12 + 3 2/12 = 6. Remember to add only the whole numbers and fractions. If you want, you can try using mathaway for additional help.
Hope this helps a little more.
Answer:
A. 40
Step-by-step explanation:
A line is equal to 180 degrees. So 180-20=160. 4x=160, x=40
Answer:
0.5781
Step-by-step explanation:
Let 'S' be the dominant allele for solid coat color and 's' be the recessive allele for spotted coat color.
By crossing a homozygous solid-colored dog (SS) with a spotted dog (ss), all of the F1 will present the Ss genotype.
When crossing two F1 dogs, the sample space for F2 is:
F2={Ss,sS,ss,SS}
For each puppy, there is a 1 in 4 chance of having a spotted coat.
The probability that at least one of the three F2 puppies have a spotted coat is 100% minus the probability that none have a spotted coat:
The probability that at least one of the three F2 puppies will have a spotted coat is 0.5781.
