Seis albañiles hicieron una barda de 180 m2 durante 12 días. ¿Cuántos días necesitaran 5 albañiles para levantar una barda de 100 m2 ?
Answer:
8 dias
Step-by-step explanation:
Primero tenemos que averiguar cuantos m2 pueden levantar los seis albañiles en 1 dia. Esto lo calculamos dividiendo los 180m2 por los 12 dias que les llevo hacerlo.
180 / 12 = 15 m2 por dia
Ahora tenemos que dividir este numero por los 6 albañiles para calcular cuantos m2 hace 1 albañil por dia
15 / 6 = 2.5
Ahora tenemos que multiplicar este m2 por los 5 albañiles que pide la pregunta
5 * 2.5 = 12.5 m2 por dia
Finalmente, necesitamos dividir los 100 m2 por los 12.5 m2 que pueden hacer los 5 albañiles por dia.
100 / 12.5 = 8 dias
Select the pair of terms that are NOT like terms. a) 3x2 , 3x3 b) -7xy, -9yx c) 8b, -0.5b d) -p2q2 , (pq)2
Answer:
b), c), d)
Step-by-step explanation:
Like terms are terms that have same variables with same powers.
a)
[tex]3x^2,3x^3[/tex] have same variable [tex]x[/tex] with different powers.
So, [tex]3x^2,3x^3[/tex] are not like terms.
b) [tex]-7xy,-9yx[/tex]
Power of [tex]x[/tex] in each of the terms = 1
Power of [tex]y[/tex] in each of the terms = 1
[tex]-7xy,-9yx[/tex] are terms that have same variables [tex]\{x,y\}[/tex] with same powers.
So, [tex]-7xy,-9yx[/tex] are like terms.
c) [tex]8b,-0.5b[/tex]
Power of [tex]b[/tex] in each of the terms = 1
[tex]8b,-0.5b[/tex] are terms that have same variable [tex]b[/tex] with same power.
So, [tex]8b,-0.5b[/tex] are like terms.
d) [tex]-p^2q^2,(pq)^2=p^2q^2[/tex]
Power of [tex]p[/tex] in each of the terms = 1
Power of [tex]q[/tex] in each of the terms = 1
[tex]-p^2q^2,(pq)^2[/tex] are terms that have same variables [tex]\{p,q\}[/tex]with same powers.
So, [tex]-p^2q^2,(pq)^2[/tex] are like terms

Step-by-step explanation:
Miles and Lucy decide to sell lemonade to earn some money. They buy pitchers, ice, and mix for a cost of $13.50. The mix makes 8 quarts of lemonade. They decide to sell one cup of lemonade for $0.75. If they sell all 8 quarts, how much revenue will they make and will they make enough to earn $12 each? (4c=1q)
Answer:
Altogether they made $24 which is enough to earn $12 each
Step-by-step explanation:
Important information:
1 cup: $0.75
4 cups = 1 quart
8 quarts of lemonade altogether
If we are looking to solve for the revenue earned based on quarts, we must first solve for how much money they make on 1 quart
Since 1 cup sells for $0.75 and 4 cups makes up a quart, we must multiply
0.75 × 4 = 3
They make $3 per 1 quart
We are looking for the amount for 8 quarts though, not just 1. Again we must multiply
3 × 8 = 24
They will make $24 if they sell all 8 quarts
The questions ask if they will each earn $12
Since there are two of them, Miles and Lucy, we must divide revenue earned by 2, the number of people
24 ÷ 2 = 12
$12
Jennifer is four less than three times Toby's age. If Jennifer is 23, then how old is Toby? equation: solution:
Answer:
T = Toby
T=(23+4)/3
Step-by-step explanation:
If Jennifer’s age is 4 less than 3 times Toby’s age then Jennifer’s age by three,
T=(23+4)/3
and 3 times that, so we divide
T=(23+4)/3
Then Toby is 9 years of age, and shouldn’t be driving.

Find the exact value of sin space 2 theta when tan theta equals negative 12 over 5 where fraction numerator 3 pi over denominator 2 end fraction less or equal than theta less or equal than 2 straight pi.
Answer:
-120/169
Step-by-step explanation:
Sin2theta = 2sintheta costheta
Given that tan theta = -12/5
Opposite = -12
Adjacent = 5
Using Pythagoras theorem
Hyp = √(-12)²+5²
Hyp = √144+25
Hyp = √169
Hyp = 13
Cos theta = adj/hyp
Cos theta = 5/13
Sin theta = opp/hyp
Sin theta = -12/13
Substitute
Sin2theta = 2(-12/13)(5/13)
Sin2theta = -120/169
Hence sin 2theta = -120/169

state true or false :every natural number is a whole number
Answer:
true , because natural number is starte on no.1 to infinity but whole no. is started on 0 to infinity so it is true .
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.

Problem 2. Smasher Van bound for Koronadal City leaves Polomolok every 15 minutes
while Nustafa Van leaves every 20 minutes.
5. How often do the two vans leave Polomolok at the same time
a. every 30 minutes
c. every 1 hour
b. every 40 minutes
d. every 2 hours
6. How many times will the Smasher Van leave Polomolok so that the two von leave
together
a. 2 times b. 3 times c. 4 times d. 5 times
7. How many times will the Nustafa Van leave Polomolok so that the two vons leave
together
a. 2 times b. 3 times c. 4 times d. 5 times
Answer:
5. c. Every 1 hour
6. c. 4 times
7. b. 3 times
Step-by-step explanation:
The given parameters of the rate of departure of the two vans are;
The rate of departure of Smasher Van bound for Koronadal City = Every 15 minutes
The rate of departure of Nustafa Van= Every 20 minutes
5. The time, 'x', when the two vans leave at the same time is given by the Lowest Common Multiple (LCM) of 15 and 20 as follows;
Multiples of 15 = 15, 30, 45, 60
Multiples of 20 = 20, 40, 60
Therefore, the LCM of 15 and 20 = 60
The time, when the two vans leave at the same time = Every 60 minutes = Every 1 hour
The time, when the two vans leave at the same time = Every 1 hour
6. The number of times the Smasher Van leaves Polomolok so that the two vans leave together is given by the number of multiples 15 minutes in 60 minutes = 60 minutes/(15 minutes) = 4 times
7. The number of times the Nustafa Van leaves Polomolok so that the two vans leave together is given by the number of multiples 20 minutes in 60 minutes = 60 minutes/(20 minutes) = 3 times.
5. c. Every 1 hour
6. c. 4 times
7. b. 3 times
Let's solve it one by one:
The given parameters of the rate of departure of the two vans are;
The rate of departure of Smasher Van bound for Koronadal City = Every 15 minutes
The rate of departure of Nustafa Van= Every 20 minutes
5. The time, 'x', when the two vans leave at the same time is given by the Least Common Multiple (LCM) of 15 and 20 as follows;
Multiples of 15 = 15, 30, 45, 60
Multiples of 20 = 20, 40, 60
Therefore, the LCM of 15 and 20 = 60
The time, when the two vans leave at the same time = Every 60 minutes = Every 1 hour
The time, when the two vans leave at the same time = Every 1 hour
6. The number of times the Smasher Van leaves Polomolok so that the two vans leave together is given by the number of multiples 15 minutes in 60 minutes = [tex]\frac{60}{15}=4\text{times}[/tex]
7. The number of times the Nustafa Van leaves Polomolok so that the two vans leave together is given by the number of multiples 20 minutes in 60 minutes = [tex]\frac{60}{30}=3\text{times}[/tex]

Answer: Choice A) The linear equation, aka straight line
Explanation:
The end behavior is determined by the ratio of the leading terms. This is because for large x values, the leading terms "drown out" (so to speak) the weight of the other terms.
We divide the leading terms 10x^3 over 2x^2 to get 5x. So as x gets really large, in either the positive or negative direction, the tail end portions will start to approach y = 5x. This is the slant or oblique asymptote. The end behavior or y = 5x has the left side going down, while the right side is going up. The same applies for the f(x) function as well.

Solve for x.2(-x - 4) = 4x + 16
a) 4
b) 3
c) -3
d) -4
Answer:
44
Step-by-step explanation:
Answer:
X=-4Step-by-step explanation:
First, we must solve for the parenthesis so...
-2x-8=4x+16
Then we must simplify this even more so lets add the 8 to 16
-2x=4x+24
Then we must subtract 4x from -2x
-6x=24
we must now divide 24 by -6 so we can isolate the x
x=-4

By selling a watch for Rs 1275, Javed lost 15%. At what price should he sell to make a profit of 10%
Answer: Rs. 1,650
Step-by-step explanation:
First find the original price of the watch.
If the watch is sold at Rs. 1,275, there is a 15% loss.
Assume the watch is x.
(1 - 15%) * x = 1,275
0.85x = 1,275
x = 1,275 / 0.85
x = Rs. 1,500
Now add a 10% markup on the original:
= (1 + 10%) * 1,500
= 1.1 * 1,500
= Rs. 1,650

Answer:
b) -9.8t +18
Step-by-step explanation:
b) The instantaneous rate of change is the derivative of the height function. The power rule is separately applied to each term, and the results added.
power rule: d/dx(x^n) = nx^(n-1)
Then the derivative is ...
dh/dt = 2(-4.9t^1) +18(1 ·t^0)
dh/dt = -9.8t +18
__
If you haven't been introduced to derivatives as such, then you find the instantaneous rate of change by finding the average rate of change over a vanishing interval.
[tex]\dfrac{dh}{dt}=\displaystyle\lim\limits_{h\to 0}{ \dfrac{h(t+h)-h(t)}{h}}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{(-4.9(t+h)^2+18(t+h)+23)-(-4.9t^2+18t+23)}{h}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{-4.9(2th+h^2)+18h}{h}=\lim\limits_{h\to 0}{(-9.8t +18 -4.9h)}\\\\ \boxed{\dfrac{dh}{dt}=-9.8t +18}[/tex]
