Step-by-step explanation:
If Mr.brown worked 20 hours and his wife wold of worked 15 hours they would both earn 120$.
Another one is if Mr.brown works 40 hours and his wife works 30 hours they each could make 240$
Hope this helps have a great day:)
Answer:
Step-by-step explanation: Browne works 4 hours and gets 24$. Wife works 3 hours and gets 24$. That's the least amount of hours for them to earn the same pay. Some other ways: Browne - 8 h and 48$, Wife - 6 h and 48$. Their hours just should be 4:3

Step-by-step explanation:
The sum of two opposite angles in a cyclic quadrilateral is equal to 180 degrees (supplementary angles)
x+44+74= 180
x+118=180
x=62
y-48+110=180
y+62=180

I WILL GIVE BRAINLIEST Suppose that is $1200 initially invested in an account at a fixed interest rate, compounded continuously. Suppose also that, after six years, the amount of money in the account is $1431 . Find the interest rate per year.
Write your answer as a percentage. Do not round any intermediate computations, and round your percentage to the nearest hundredth.
Answer:
so we know that we're starting with $2500. We know it's compound a continuous interest, and they tell us that the interest rate is 6% and we want to find the amount of time it's going to take for it to basically double because it says 5000. So we divide both sides by five Excuse me by 2500 and we end up with E to the 0.6 T is equal to two. We can take the natural log of both sides mhm, and we can use a log of a powers at this point. Oh, 60 can come down in front with log of a power and lo and behold Oh, my goodness, Ellen up e is one. So all we need to do to solve is divide both sides by 0.6, and that will give us our time. We need to round that off to the nearest 10th of a year. So Ln of two divided by 20.6 11.6 11.55 But to the nearest Tampa would be 11.6 years. And we are done. Mm hmm.

5 - 4(2 - x) = 17
solve for x
Answer:
x = 5
Step-by-step explanation:
I just solved the equation!
5 - 4(2-x) = 17
-4(2-x) = 12 (subtract by 5 on both sides)
2 - x = -3 (divide by 4 on both sides)
-x = -5 (subtract by 2 on both sides)
x = 5 (divide by -1 on both sides (two negatives cancel out!))
:)
Answer:
x = 5
Step-by-step explanation:
1) Subtract 5 from both sides.
-4(2-x)=17-5
2) Simplify 17 - 5 to 12.
-4(2-x)=12
3) Divide both sides by -4.
2-x=-12/4
4) Simplify 12/4 to 3.
2-x=-3
5) Subtract 2 from both sides.
-x=-3-2
6) Simplify - 3 - 2 to -5.
-x=-5
7) Multiply both sides by -1.
x = 5
Check the answer:
5-4(2-x)=17
1) Let x=5.
5-4*(2-5)=17
2) Simplify 2-5 to 3.
5-4*-3=17
3) Simplify 4 * -3 to -12.
5-(-12)=17
4) Remove parentheses.
5+12=17
5) Simplify 5 + 12 to 17.
17 = 17
All done !
Can u find x? with work
Find y and Find z??? Plsss thank youuu
Answer:
Step-by-step explanation:
If two triangles are similar to each other, that means all their angle are equal, which means in this case that:
Angle DEF = Angle DGFAngle EDF = Angle GDFAngle DFE = Angle DFGThat means we get the equation:
3x = 24 --> x = 8
9y = 108 --> y= 12
z = 360 - 24 - 108 = 226
Thus x = 8, y = 12, and z = 226

Ill Give Brainlyiest The height of pyramids in Egypt is normally distributed. A sample of 125 pyramids had a mean height of 460.7 ft and a standard deviation of 4.1 feet. With 80% confidence, what is the maximum error of estimate for the actual population mean for the height of Egyptian pyramids?
37.04%
47.01%
4.21%
94.43%
Using the t-distribution, as we have the standard deviation for the sample, it is found that the the maximum error of estimate for the actual population mean for the height of Egyptian pyramids is of 47.01%.
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sampleThe margin of error is:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]
The critical value, using a t-distribution calculator, for a two-tailed 80% confidence interval, with 125 - 1 = 124 df, is t = 1.2884.
The other parameters are: [tex]\mu = 460.7, s = 4.1, n = 125[/tex].
Hence, the margin of error is of:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]
[tex]M = 1.2884\frac{4.1}{\sqrt{125}}[/tex]
[tex]M = 0.47[/tex]
Hence, the maximum error of estimate for the actual population mean for the height of Egyptian pyramids is of 47.01%.

The required ways to rewrite 3xy + 6yz are as follows,

C. 3y(x + 2z)
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression,
= 3xy + 6yz - - - -- (A)
The distributive property is given as,
a [b + c] = ab + ac
Taking 3 common
= 3(xy +2yz) - - - - - -(1)
In equation A taking 3y common.
= 3y(x + 2z) - - - - - - - (2)
In equation A taking y common.
= y(3x + 6z) - - - - -- - - - (3)
Thus, the required ways to rewrite 3xy + 6yz are as follows,
A. 3(xy +2yz)
B. y(3x + 6z)

7/12 cannot be simplified
5/10 = 1/2 = 6/12
We can see, that the order is 6/12, 7/12, 8/12. Now we change it back to its original numbers, 5/10, 7/12, 4/6

A bus travels with a constant speed of 43 miles per hour. How long will take to travel 60 miles Wirte your answer as a
decimal number
hours
Answer:
1.395 hours
Step-by-step explanation:
Time is proportional to distance, and inversely proportional to speed. The relationship is ...
time = distance/speed
For the given speed and distance, the time is ...
time = (60 mi)/(43 mi/h) = 60/43 h ≈ 1.395 h
At 43 mph, it will take about 1.395 hours to travel 60 miles.

During natural selection, organisms with harmful traits are less likely to successfully reproduce than organisms with beneficial traits. Neutral traits don’t improve or hurt an organism’s chances for survival. So, they tend to persist in populations when environmental conditions are stable. If the environment changes, neutral traits could become harmful or beneficial depending on the situation. In year 1, a population of rain forest plants has the following distribution: 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves. You will simulate three years of this population: year 1, year 5, and year 10. How will the trait distribution most likely change over this time?.
Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selectionNatural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.
All of these mechanisms can make a population evolve, or change its genetic makeup over generations.
But there's one mechanism of evolution that's a bit more famous than the others, and that's natural selection. What makes natural selection so special? Out of all the mechanisms of evolution, it's the only one that can consistently make populations adapted, or better-suited for their environment, over time.
You may have already seen natural selection as part of Darwin’s theory of evolution. In this article, we will dive deeper – in fact, deeper than Darwin himself could go. We will examine natural selection at the level of population genetics, in terms of allele, genotype, and phenotype frequencies.
