Answer:

55 minutes

Step-by-step explanation

   He started waiting at 12:35 P.M. If we're assuming this is the same day, you're able to add the minutes until you get to 1:00 P.M., which is around 25 minutes. Afterwards, you need to add another 30 minutes to get to the train's time of arrival, which means you should get 55 minutes!

Answer:

D

12w + 140 = 356

Step-by-step explanation:

Her goal is to save up 356$. She already has 140$, and wants to save 12$ per week. We're trying to find how many weeks it would take.

You must multiply 12 by the number of weeks, which elimates the first two equations. We're also trying to add together 140 and the 12x because we want the total to ADD to 156.

Hopefully this makes sense, and ask any remaining questions about this in the comments. If you liked my explaination, feel free to give a Brainliest :P

If there are 30 boys and 15 girls in the room

We have :

Boys : Girls

30 : 15

a) 30 : 15

Dividing through by 3

= 10:5

b) 30 : 15

Dividing through by 5

= 6:3

c) 30 : 15

Dividing through by 15

The area of the shaded region is 60 square units.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

To find the area of the shaded region, we need to subtract the area of the rectangular region that was removed from the larger rectangular region.

The area of the larger rectangle is:

11 x 8 = 88

The area of the rectangle that was removed is:

7 x 4 = 28

So, the area of the shaded region is:

88 - 28 = 60

Therefore, the area of the shaded region is 60 square units.

Answer:

2x^2+3x+3

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2"   was replaced by   "x^2".  1 more similar replacement(s).

STEP  1

The Equation at the end of step 1

 (3x2 +  5x) -  x2) -  2x) +  3

STEP  2

Trying to factor by splitting the middle term

2.1     Factoring  2x2+3x+3  

The first term is,  2x2  its coefficient is  2.

The middle term is,  +3x  its coefficient is  3.

The last term, "the constant", is  +3  

Step-1: Multiply the coefficient of the first term by the constant   2 • 3 = 6  

Step-2: Find two factors of  6  whose sum equals the coefficient of the middle term, which is   3.

     -6    +    -1    =    -7  

     -3    +    -2    =    -5  

     -2    +    -3    =    -5  

     -1    +    -6    =    -7  

     1    +    6    =    7  

     2    +    3    =    5  

     3    +    2    =    5  

     6    +    1    =    7  

Observation: No two such factors can be found !!

Conclusion: Trinomial can not be factored

Final result :

 2x^2 + 3x + 3

Answer:

The distance is 5 units.

Step-by-step explanation:

Key Skills needed for this problem: Distance Formula, Coordinate Plane Understanding, Radicals, Subtraction, Exponents, Addition

1) We are given 2 points --> (-1,2) and (3,5)

2) To find out the distance between both, we use distance formula.

This is: Given 2 points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex], the distance between the 2 points would be: [tex]\sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}[/tex].

3) For the points (-1,2) and (3,5):

4) Therefore it would be --> [tex]\sqrt{(-1 - 3)^{2} + (5-2)^{2}}[/tex]

5) This simplified would be [tex]\sqrt{(-4)^{2} + 3^{2}}[/tex]

6) This further simplified would be: [tex]\sqrt{16 + 9}[/tex]

7) This even more simplified would be [tex]\sqrt{25}[/tex] which is 5.

Therefore, the distance between the 2 points is 5 units.

Rewrite the fractions to have a common denominator to find the difference:

2/3 = 4/6

Difference = 4/6-5/6 = -1/6

Sequence formula = an = a1 + d(n-1)

A1 is the first term 5/6

And d = -1/6

Sequence = 5/6 -1/6(n-1)

Simplify to get an =(-n +6)/6

Step-by-step explanation:

Rigid transformations and dilation will result in similar figures. Choices B, C, and D are not rigid transformations or dilations, but are different stretches in one direction than another.

The transformation of A is a dilation by a factor of 2 and reflection over the y-axis. It results in similar figures.

Using compound interest, it is found that Melanie would need to invest a value of $7,710.

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In this problem, we have that:

Hence:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]11900 = P\left(1 + \frac{0.031}{365}\right)^{365(14)}[/tex]

[tex]1.54339P = 11900[/tex]

[tex]P = \frac{11900}{1.54339}[/tex]

[tex]P = 7710[/tex]

Melanie would need to invest a value of $7,710.

Answer:

y=-5x+1

Step-by-step explanation:

First lets identify what slope intercept form looks like:

y=mx+b

m=slope

b=y-intercept

the y-intercept would be at (0,1)

choose 2 points from the graph and lets find the slope.

The formula for slope is:

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1} }[/tex]

The points we will be using will be (1,-4) and (2,-9)

so -9 will be [tex]y_{2}[/tex] and -4 is [tex]y_{1}[/tex]

2 is [tex]x_{2\\}[/tex] and 1 is [tex]x_{1}[/tex]

set up the equation.

[tex]\frac{-9-(-4)}{2-1}[/tex]

[tex]\frac{-5}{1}[/tex]

m = -5

So the slope is -5 and the y-intercept is 1

[To find the y-intercept all you have to do is find what y is counting by. In this is would be -5. Go backwards one on the table so x is 0 and take away -5 and it will give you 1 which would be the intercept]

So the equation will be

y=-5x+1

Now when you want to solve it you plug in the x and y values for the table but it doesn't ask you to do that,

I've included a picture so you have a visual.

Answer:

Interest=$3600

Step-by-step explanation:

I = P * r * x * t

Where:

P is the principal amount, $12000.00.

r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.

t is the time involved, 6....year(s) time periods.

So, t is 6....year time periods.

To find the simple interest, we multiply 12000 × 0.05 × 6 to get that:

The interest is: $3600.00

Usually now, the interest is added onto the principal to figure some new amount after 6 year(s),

or 12000.00 + 3600.00 = 15600.00. For example:

If you borrowed the $12000.00, you would now owe $15600.00

If you loaned someone $12000.00, you would now be due $15600.00

If owned something, like a $12000.00 bond, it would be worth $15600.00 now.

Equation: y=$3(x)+$30

Total cost $42

Step-by-step explanation:

Calculation to Find the total cost of 4 hours at the aquarium using this formula

y=mx+b

Where,

y intercept=Total cost

m=$3 per hour

b=$30 Tickets

x=4 hours

Let plug in the formula

First step is to form the equation

y=$3(x)+$30

Second step is to substitute 4 hours for m and b

y=$3(4)+$30

Hence:

y=$12+$30

y=$42

Therefore the equation will be y=$3(x)+$30 while the total cost of 4 hours at the aquarium will be $42

Answer:

(6x - 7) (6x - 7)

Step-by-step explanation:

A perfect square trinomial will be in the form of [tex]a^2[/tex] ± [tex]2ab + b^2.[/tex] A trick to factoring a perfect square trinomial would to write it as [tex](a^2[/tex]±[tex]b^2)[/tex]. (When doing this, the sign in the middle is determined by the middle sign in the original trinomial).

[tex]36x^2 -84x + 49[/tex] is known as a perfect square trinomial, too. Its first and last terms are both perfect squares (6x squared makes [tex]36x^2[/tex], 7 squared makes 49) and the middle term is 2 times the square roots of both of the other terms ( [tex](2) (7) (6x)[/tex] is [tex]84x[/tex]).

So, we can use the trick described earlier, and the answer would be [tex](6x-7)^2[/tex], also known as (6x-7) (6x-7).
