Juan, Pedro y Luis construyen un muro de 60 metros de largo. Juan construye el triple de Pedro y Luis el doble de Juan. ¿Cuántos metros construyó cada uno?
Answer:
Pedro make 6 m of wall, Juan make 18 m of the wall and Luis make 36 m of the wall.
Step-by-step explanation:
Juan, Pedro and Luis build a 60 meter long wall. Juan builds triple the size of Pedro and Luis double the size of Juan. How many meters did each one build?
Total length of the wall is 60 m.
Let Pedro make p length of the wall.
Juan make = 3 p
Luis make = 6 p
So,
According to the question
60 = p + 3 p + 6 p
60 = 10 p
p = 6
So, Pedro make 6 m of wall, Juan make 18 m of the wall and Luis make 36 m of the wall.
What is the correct answer to this multiple choice question? Please help!

If $10,500 is borrowed for 5 years at an annual simple interest rate of 1.73%, how much interest will be paid if the entire loan is paid off at the end of the fifth year? Enter the answer in dollars and cents, and round to the nearest cent, if needed. Do not include the dollar sign. For example, if the answer is $0.61, only the number 0.61 should be entered.
Answer:
Step-by-step explanation:
So, yearly $2100 is paid, plus the 1.73% interest, so 1.73% interest is $2136.33every year interest stacks on itself so youll take 1.73% of the year 1 total with interest.

Answer:
? = 36 degrees
Step-by-step explanation:
To find this measure, we use the appropriate trigonometric ratio
from the question, the angle faces the length 26 which represents the opposite
the length 44 faces the angle 90, which is the hypotenuse
The trigonometric ratio that connects both is the sine
The sine of an angle is the ratio of the opposite to the hypotenuse
Thus;
sine ? = 26/44
? = arc sine (26/44)
? = 36

PLS how to do this 3 sums
Answer:
Step-by-step explanation:
7) PQ // RS, RQ is transversal
x = 38 {Alternate interior angles are congruent}
In ΔPQR ,
x + y + ∠P = 180 {Angle sum property of triangle}
38 + 90 + y = 180
128 + y = 180
y = 180 - 128
y = 52
9) Construct XY // AB
XY // AB & AC is transversal
∠1 = ∠4 ---------(I) {alternate interior angles are equal}
XY // AB & BC is transversal
∠3 = ∠5 ---------(II) {alternate interior angles are equal}
∠1 + ∠2 + ∠3 = 180 {straight line angles}
∠4 + ∠2 + ∠5 = 180 {From (I) & (II) }
Sum of three angles of triangle is 180.Hence proved.

The measure of two supplementary angles are A=(4a+7)° and B=(a-2)° find the measure of the two angles
Answer:
147˚, 33˚
Step-by-step explanation:
supplementary angles means those angles add up to 180˚
so A+B = 180
substitute A and B with the values given.
(4a+7) + (a-2) = 180
combine like terms
5a + 5 = 180
5a = 175
a = 35
Now that we have a, substitute in the actual value of a into the expressions for each angle.
for <A: 4(35) + 7 = 147˚
for <B: 35 - 2 = 33˚
Answer:
<A =147
<B = 33
Step-by-step explanation:
Supplementary angles add to 180
4a+7 + a-2 = 180
5a+5 = 180
5a+5-5 = 180-5
5a = 175
Divide by 5
5a/5 = 175/5
a = 35
<A = 4a+7 = 4*35 +7 = 140+7=147
<B = a-2 = 35-2 = 33
eric has a summer lawn mowing buisness. based on experience eric knows that p= -3x^2 + 150x -1200 models his profit, p, in dollars, where x is the amount he charges per lawn. how much does he need to charge if he wants to break even? show your work
Answer:
Eric can either charge $10 or $40 in order to break even.
Step-by-step explanation:
Eric has a summer lawn mowing business and the equation:
[tex]p=-3x^2+150x-1200[/tex]
Models his total profit p by charging x dollars per lawn.
We want to determine what price Eric needs to charge in order to break even.
The price Eric charges to break even means that his total profit will be zero. Hence, we can let p = 0 and solve for x. Thu:
[tex]0=-3x^2+150x-1200[/tex]
We can divide both sides by -3:
[tex]0=x^2-50x+400[/tex]
Factor:
[tex]0=(x-10)(x-40)[/tex]
Zero Product Property:
[tex]x-10=0\text{ or } x-40=0[/tex]
Solve for each case. Hence:
[tex]x=10\text{ or } x=40[/tex]
Therefore, Eric can either charge $10 or $40 in order to break even.

Kara Danvers (Supergirl) has always relied on her strength to win fights. But what happens when she meets an alien just as strong? Her sister is training her to be a more technical fighter so that Supergirl can meet any challenge. The data below record the significant strikes during randomly selected training sessions 6 months apart. Is Kara showing improvement in her fighting?
Strikes (pre): 29 32 44 34 19
Strikes (post): 51 45 68 92 64
Write the Hypotheses:
H_0:_______________, the mean difference in ___________ between ____________ and ______________ is _______________
H_a:_______________, the mean difference in ___________ between ____________ and ______________ is _______________
Answer:
H0 : The mean difference in strikes between pre and post strike is equal to 0
H1 : The mean difference in strikes between pre and post strike is not equal to 0
Step-by-step explanation:
The scenario described abibe meets the condition for a paired (dependent) sample t test as the same subject is involved in both the pre and post strike data. Therefore measurement from the strike(pre) must be paired with measurement from the strike(post) data.
For a paired test involving a single subject ; The mean difference in the two sample is 0 ; that is both are the same while the alternative negates the null by claiming that the mean difference is not equal to zero.

Which statement about the annual percentage rate (APR) is true?
a.If you have good credit, you will get a higher APR.
b.If the APR is 5%, you will pay 5% of the balance per month.
c.The APR is not a good way to compare loans.
d.The APR helps compare loans with the same payback period, but with different monthly rates and different fees.
Answer:
d. The APR helps compare loans with the same payback period, but with different monthly rates and different fees.
Step-by-step explanation:
A loan can be defined as an amount of money that is being borrowed from a lender and it is expected to be paid back at an agreed date with interest.
Generally, the financial institution such as a bank lending out the sum of money usually requires that borrower provides a collateral which would be taken over in the event that the borrower defaults (fails) in the repayment of the loan.
An annual percentage rate (APR) is an amount of money paid as interest by borrowers or earned on loans by lenders such as banks, expressed as a percentage of the amount borrowed or invested over a 12-month period i.e on an annual basis.
Generally, the annual percentage rate (APR) helps compare loans with the same payback period, but with different monthly rates and different fees.
Answer:
A- If you have good credit, you will get a higher APR

when servicing a heating boiler and radiators, a plumer knows that the time he will take is given by the formula
time = 1 hour + 45 minutes per radiator
he charges his costumer a call-out fee of £30, plus £20 per hour
how much should a costumer be charged for servicing a heating boiler and four radiators
Answer:
£110
Step-by-step explanation:
We know how much time it takes for a boiler and a radiator, and we need to know how much it will cost for 1 boiler and 4 radiators. We have an initial cost of £30, and since hes doing a boiler - which we know takes an hour - we can already add £20 for a start of £50.
Now, there are 4 radiators, that take 45 minutes each. We need to use this equation:
[tex](45*4)/60[/tex]
We divide by 60 because there are 60 minutes in an hour, and he charges by hour. So:
[tex]180/60=3[/tex]
Now, to find out how much to charge, we need to figure out how much to add to the £50. Since it's £20 an hour, and it takes 3 hours to do the 4 radiators, we need to multiply:
[tex]3*20=60[/tex]
Now we add our totals for a grand total of...
[tex]50+60=110[/tex]
Solve the inequality 4 is greater than n over -4
Answer:
4 > [tex]-\frac{n}{4}[/tex]
-16 > n
Step-by-step explanation:
Greater than would mean that the "arrow" is not facing the number. It would mean it is larger than the other number. Also, you have to construct the other part of the inequality which would be [tex]-\frac{n}{4}[/tex].
4×4 > [tex]-\frac{n}{4}[/tex]×4
16 > -n
-16 > n

There are 50pupils in a class .Out of this number 1/10 speak French only and 4/5 of the reminder speak both French and English.lf the rest speak English only,find the number of student who speak
a.both French are English
b.only English
Answer:
40 pupils speak French and English
5 pupils speak only English
Step-by-step explanation:
**The grammar has some errors, but I hope I understood it correctly to answer your question correctly!**
Here's what we know about the question:
- 1/10 of the 50 pupils speak only FRENCH
- 4/5 of the 50 pupils speak FRENCH and ENGLISH
- rest of the pupils speak only ENGLISH
Here's what we're trying to find:
- # of pupils that speaks FRENCH and ENGLISH
- # of pupils that speak only ENGLISH
Let's start of with find how many pupils speak French:
1/10 of the 50 pupils speak French. To find the # of pupils, divide 50 by 10:
50/10 = 5
5 pupils speak only French
Now let's find out how many pupils speak French and English:
4/5 of the 50 pupils speak French and English. We are going to divide 50 by 5 and then multiply the result by 4:
50/5 = 10
10 * 4 = 40
40 pupils speak French and English
Finally, let's find the number of pupils that speak only English:
The question only says that the rest of the 50 pupils speak only English.
We are going to add the other pupils who don't speak only English, then subtract that value from 50:
40 + 5 = 45
50 - 45 = 5
5 pupils speak only English
Hope that helps (●'◡'●)
