PLEASE HELP ME.....

Mathematics
1 answer:
Virty [35]4 years ago

Answer:

They would meet each other at 01 : 24 PM.

Step-by-step explanation:

  • Erik took a trip to see his friend Mike who lives 308 miles away.
  • He left his place at 10 AM driving at 70 mph.
  • In 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph.

As Erik left his house at 10 AM driving at 70 mph and in 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph. It means

Erik left his place at 12:00 PM noon.

so, at 12:00 PM Erik had already traveled:

                                                                      2\times 70=140\:\:miles

Miles left =308-140=168\:\:miles

Let 't' be the time when they meet

so

70t\:+\:50t\:=168

120t=168

\mathrm{Divide\:both\:sides\:by\:}120

\frac{120t}{120}=\frac{168}{120}

t=\frac{7}{5}

so

t=\frac{7}{5}=1.4\:\:hours

or 1 hour and 24 minutes after 12:00 noon

i.e.

12\:+\:1.4\:=1\:O'clock\:+\:24\:minutes

Therefore, they would meet each other at 01 : 24 PM.

Assume that you invest in U.K. stocks. After one year, the domestic return on U.K. stock is 9.5% and the dollar has fallen by 4%
max2010maxim [7]

Answer:


Step-by-step explanation:

I think the question is faulty.

Suppose you have 1000 dollars invested in the UK financial instrument. It returns 9.5%.  9.5% of 1000 dollars is (9.5/100) * 1000 = 95 dollars. If you bring that 95 dollars back to the US, you get an additional 4% because of the exchange rate. (This assumes that the 95 is in British Pounds). So 4% of 95 is about 3.80 US dollars. That brings the total up to (98.80/1000)* 100% which is about 9.88%. No such answer exists.

The question is so unclear that a number of other answers are possible. But none are going to be as high as 13% or as low as 5.5% or even 8%.

Discussing the 8% is worth a bit of time. When you bring in the US dollars the pound conversion gives you an extra 4%. The amount of money will go up, not down.

13% is arguably right only if you repatriate the 1000 dollars, but the problem did not make clear that was what was happening.

I don't know what answer you should pick. 9.5% is the closest answer so it is perhaps what you should pick, but it is not correct.

3-11x ≤ 36<br>3- x &gt; 2<br>2x + x &gt; 12<br>Need work
Bas_tet [7]
3 - 11x < 36 ( I can’t make the signs have a line underneath them, but I do mean for there to be a line)
Subtract 3 from both sides
-11x < 33
When you divide a negative, the sign flips
x > -3

3 - x > 2
Subtract 3 sides
-x > -1
x < 1

3x > 12
x > 4

Hope this helps!

Fernanda and Jose were working on an assignment in their geometry class in which they were to write the equation of the graph be
Alborosie

Answer:

yes they both are wrong

Step-by-step explanation:

Center of the Circle is (h,I) which is (4,-3)

so h= 4 and k = -3

radius is 4 units (3+1)

Equation for circle

(x - h) {}^{2}  + (y - k) {}^{2}  = r {}^{2}

substitute all the values in this equation

(x  - 4) { }^{2}  + (y - ( - 3)) {}^{2}  = 4 {}^{2}  \\ (x - 4) {}^{2}  + (y + 3) {}^{2}  = 16

someone please help me...Im so confused..I need a teacher who really good at explaining &amp; solving things
Mumz [18]

Answer:

The numbers to insert are 3  and 1 as the equation of the line is y = 1/3 x + 1.

Step-by-step explanation:

First we find the slope of the line.

Note that the line passes through the points (0,1) and  (-3,0)

The slope = (y2 - y1) / (x2 - x1)    where (x1, y1) and (x2, y2) are points on the line.

So the slope of our line = (0 - 1) / (-3 - 0)

= -1/-3

= 1/3

Now the y-intercept ( that is the point where the line passes through the y-axis) is at y = 1.

So using the  slope-intercept form of a straight line:

y = mx + c     where m = slope and c = y-intercept.

We plug in m = 1/3 and c = 1 to give the answer:

y = (1/3)x + 1.
