Answer:
B:0.2(48)
Step-by-step explanation:
Of means multiply
20% of 48
Changing to decimal form
.20 * 48
The answer is 43.6 liters
Explanation:
So we want to find out how many liters are in 48 quarts. The first step would be to find other how many liters are in 1 qt, which is about 0.95 liters. Now that we know there are 0.95 liters in 1 qt, to solve for 48 qts, we multiply by 0.95. 0.95 x 48 = 45.6. Since 43.6 is closest to our rounded answer, 45.6, there are about 43.6 liters in 48 qts.
Responda:
1.) 6;
2.) d) O pai tem 36 anos e o filho tem 12 anos.
Explicação passo a passo:
1.)
Dada a equação: 3x - 4 = 14
3x = 14 + 4
3x = 18
Divida os dois lados por 3
x = 6
2) Dado que ;
Idade do pai = 3 vezes a idade do filho
Idade do pai + idade do filho = 48
Deixe a idade do pai = f; idade da criança = c
Matematicamente ;
f = 3c - - - (1)
f + c = 48 - - - - (2)
Substitua f = 3c em (2)
3c + c = 48
4c = 48
c = 48/4
c = 12
Substitua c = 12 em (2)
f + 12 = 48
f = 48 - 12
f = 36
Portanto ;
Idade do pai = 36 Idade da criança = 12
Answer:
<h2> 105 tickets</h2>
Step-by-step explanation:
To solve this problem we need to model an equation to represent the situation first.
the goal is to archive $7500 in the even, bearing in mind that there is a cost of $375 fee for rent, we need to put this amount into consideration
let the number of tickets be x
so
75x-375>=7500--------1
Equation 1 above is a good model for the equation
we can now solve for x to determine the number of tickets to be sold to archive the aim
75x-375>=7500--------1
75x>=7500+375
75x>=7875
divide both sides by 75 we have
x>=7875/75
x>=105 tickets
so they must sell a total of 105 tickets and above to meet the target of $7500 with the rent inclusive
Check the picture below.
now, the "x" is a constant, the rocket is going up, so "y" is changing and so is the angle, but "x" is always just 15 feet from the observer. That matters because the derivative of a constant is zero.
now, those are the values when the rocket is 30 feet up above.
