(4+x) divided by 12.

im stuck heree :(

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:

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.

Answer:

Only A, the first equation is true.

Step-by-step explanation:

A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true

B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.

Answer:

$6

Step-by-step explanation:

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  

Answer:

1080 m^2 Don't submit m^2 in your answer.

Step-by-step explanation:

Givens

The catch is to find h

To do that, use a^2 + b^2 = c^2

a b and c are in the same 1/2 triangle.

a = 48/2 = 24 m

b = h = ?

c = 51 meters

Solution

a^2 + b^2 = 51^2                      Substitute for b^2 = h^2

24^2 + h^2 = 51^2                   Expand 24^2 and 51^2

576 + h^2 = 2601                    Subtract 576 from both sides

h^2 = 2601 - 576

h^2 = 2025                              Take the square root of both sides

h = 45

Area

Area = 1/2 b * h

Area = 1/2 48 * 45

Area = 1080

Remark

Notice that to find h you only use 1/2 of 48 because that is the base of the right triangle.

To find the area, you need to use all of 48 because 48 is the full length of the base.

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.

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.

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.
