When Ellen’s family had completed 70% of a trip, they had traveled 35 miles. How far is the trip overall? (I need a number sentence/A complete sentence)

Answers

Answer:

If Ellen traveled 35 miles and this was 70% of her trip, then 100% of her trip would be 50 miles.

Step-by-step explanation:

You can solve this by setting up a proportion. 35/70 = ?/100. To solve this, cross-multiply 35 and 100 to get 3,500. Divide this by 70 and get 50. This means that 35/70 = 50/100.

Li bought his dog Spot a huge bone that is 15 inches long. Spot chews 4 inches off the bone every day. What is the new length of the bone after 3 days?

Answers

Answer:

3 inches

Step-by-step explanation:

If the dog chews off 4 inches every day, you first have to multiply the inches by the number of days, which in this case is 3 x 4, which equals 12. In 3 days, he chewed off 12 of the original 15 inches, leaving only 3 inches left.

What equation is equivalent to 2+3(2x+4)=13

Answers

Answer:

14+6x=13, or further 1+6x=0

Step-by-step explanation:

2+3(2x+4)=13,

Distribute the 3 into the parenthesis:

2+6x+12=13

Now combine like terms: 14+6x=13.

You can also write this as 1+6x=0 by subtracting 13 to the left, though it might not be necessary.

Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok

Answers

Answer:153

Step-by-step explanation:

From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.

If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:

= 3/25 × 1280

= 153.6

There will be 153 students expected

Answer:

1. no, 2. yes

Step-by-step explanation:

You need to use the triangular inequality thereom, which goes by if any side lengths are added together, they are greater than the remaining one. So, for number one, although 20+9=29>8 and 20+8=28>9, 9+8<20 since 9+8=17, which is less than 20. For number two, yes because 1) it is a right triangle triple and 2) 3+4=7>5, 4+5=9>3, and 5+3=8>4.

Answer:

Number 1 is Not a triangle so No and you don’t need to classify becuase it’s not aa triangle

Number 2 is a triangle becuase its ta Pythagorean triplet and even if you checK, it adds up.

Step-by-step explanation:

1) So using Pythagorean Theorem

8^2+9^2=20^2

64+91=400

That is not true

2) 3^2+4^2=5^2

9+16=25

That is true

Bart had an income of $38,250 last year. If the inflation rate is 4.5%, what is his purchasing power?

A. $33,614.85
B. $34,543.75
C. $34,998.15
D. $36,528.75
​

Answers

Answer:  D) $36,528.75

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

Explanation:

Positive inflation eats away at the purchasing power of money.

If inflation is 4.5%, then the purchasing power goes down by 4.5% meaning his purchasing power is 100% - 4.5% = 95.5% of what it used to be.

95.5% of $38,250 = 0.955*38250 = 36,528.75

So his purchasing power is $36,528.75

The purchasing power of Bart by the income of last year is option D. $36,528.75.

What is Inflation?

Inflation can simply be defined as the increase in the rate of the prices over a period of time. In other words, inflation describes how much more expensive has a commodity or service becomes in a period of time.

It is clear that, inflation decreases the purchasing power of money.

Given that, the inflation rate is 4.5%.

Also, Bart had an income of $38,250 last year.

Purchasing power will get decreased by 4.5%.

Purchasing power = $38,250 - ($38,250 × 4.5%)

                              = $38,250 - (1721.25)

                              = $36,528.75

Hence the purchasing power of Bart is $36,528.75.
