Answer:

X + 3

Step-by-step explanation:

There is no definite working. The first container is what I call the base because everything is a little above the first container, X. They are basically asking you what is the total of the four jars bigger than X. In other words how many steps more to climb before the top floor while you are on the first step. So then you add the other numbers like 0.5 etc which will give you X +3. Hope it helps.

Allison is buying movie tickets for she and her friends. The price of each ticket is $8.50 and she spent a total of $42.50. Writ

pochemuha

P = price of tickets
8.50p = 42.50

you then divide 8.50 on both sides
8.50p = 42.50
——— ———
8.50 8.50
p = 5

meaning Allison bought 5 tickets in total.

Sum n=3 ^ infty (2n+5)<br>find the series shown

Margarita [4]

<h3>Answer: Choice C) 11 + 13 + 15 + 17 + ...</h3>

=====================================================

Explanation:

We're adding terms in the form (2n+5)

The first term is when n = 3, so

2n+5 = 2*3+5 = 6+5 = 11

The next term is when n = 4, so

2n+5 = 2*4+5 = 8+5 = 13

The next term is when n = 5, so

2n+5 = 2*5+5 = 10+5 = 15

And so on

This means,

$\displaystyle \sum_{n=3}^{\infty} (2n+5) = 11+13+15+17+\ldots$

which matches with choice C. The three dots indicates the pattern goes on forever.

-------------------

Choice B does not have these dots, so that's why choice B is not the answer. If we replaced the infinity symbol with 7, then choice B would be the answer.

I.e,

$\displaystyle \sum_{n=3}^{7} (2n+5) = 11+13+15+17+19$

La edad de 4 miembros de una familia suman 70. Mamá es 6 veces más grande que su hijo y 10 veces más grande que su hija. Papá es

3241004551 [841]

Answer:

3 5 30 32

Step-by-step explanation:

The question in English is

The age of 4 members of a family adds up to 70. Mom is 6 times bigger than her son and 10 times bigger than her daughter. Dad is 2 years older than Mom. How old are each of the family members? Write the result in ascending order and separated by spaces

Let

x----> Mon's age

y----> Son's age

z----> Daughter's age

w---> Dad's age

we know that

x+y+z+w=70 -----> equation A

x=6y ----> y=x/6 -----> equation B

x=10z ----> z=x/10 -----> equation C

w=2+x -----> equation D

substitute equation B, C and D in equation A and solve for x

x+(x/6)+(x/10)+(2+x)=70

Multiply by 60 both sides

60x+10x+6x+120+60x=4,200

136x=4,200-120

x=4,080/136

x=30 years

Find the value of y

y=x/6 -----> y=30/6=5 years

Find the value of z

z=x/10 ----> z=30/10=3 years

Find the value of w

w=2+x ----> w=2+30=32 years

Write the result in ascending order and separated by spaces

Suppose you have a coin collection of dimes and quarters containing 46 coins. If you have 6.70 dollars, how many of each type of

NNADVOKAT [17]

Answer:

The number of dimes = 32

The number of quarters = 14

Step-by-step explanation:

Here, the total number of coins combined = 46

Let us assume the number of dimes = m

So, the Number of quarter = Total Coins - Number of dimes = 46 - m

Now,as we know:

1 dime = $0.1

So, m dimes = m x ($0.1) = $(0.1 m)

1 Quarter = $0.25

So, ( 46 - m ) Quarters = (46 - m ) x ( $ 0.25) = 11.5 - 0.25 m

Also, given the total amount of coins = $ 6.70

⇒ Value of (Dimes + Quarters) = $ 6.70

or, (0.1 m) + 11.5 - 0.25 m = 6.70

-0.15 m = - 4.8

or, m = 4.8/0.15 = 32

⇒ m = 32

Hence, the number of dimes = m = 32

And the number of quarters = 46 - m= 46 -32 = 14
