by what percentage did the high temperature increase from friday to saturday ? round ur answer
Answer:
Step-by-step explanation:
First, you must find the actual decrease in temperature.
Decrease = Yesterday's temperature - Today's temperature
Decrease = 80 - 75
Decrease = 5 degrees
Now, find the percentage decrease.
% Decrease = Actual decrease / Yesterday's temperature x 100
% Decrease = 5/80 x 100
% Decrease = 0.0625 x 100
% Decrease = 6.25 %
So, the percent decrease in high temperature from yesterday to today is 6.25%

helpppppppppppppppppppp
Answer:
[tex] \frac{x + 2}{x - 2} [/tex]
Step-by-step explanation:
This is much easier to solve actually since both expressions have the same denominator.
To solve it therefore,just sum the numerators
(x²-4x-2)+(8x+6)
x²+4x+4 Now divide by the common denominator
x²+4x+4/x²-4
Factorize both numerator and denominator
(x+2)(x+2)/(x-2)(x+2)
Cancel out common terms
x+2/x-2

please help me
please help!! please show your work too so i know how to do the rest of them :)
Answer:
Step-by-step explanation:
1) f(x)=1/3(x+1)^2
so if we use the equation f(x)=a(x-h)^2+k then we can plug in the different things. a would represent the compress/stretches, so in order to move horizontally, we would need to do 1/3
for h: that is the horizontal translations so, left and right. BUT remember it's the opposite. so if you want to go left <-- you would have to put a + sign and to go right you would have to put a - sign.
I hope that helps it prob is confusing sorry >-<
HELP PLEASE solve for d
d= 1- 4bh
Step-by-step explanation:
- 8b = 2d - 2/h
Multiply both sides of the equation by h.
- 8bh = 2d - 2
Swap sides so that all variable terms are on the left-hand side.
2d - 2 = - 8bh
Add 2 to both sides.
2d = - 8bh + 2
The equation is in standard form.
2d = 2 - 8bh
Divide both sides by 2.
2d/2 = 2 - 8bh/2
Dividing by 2 undoes the multiplication by 2.
d = 2 - 8bh/2
Divide -8bh + 2 by 2.
Therefore: d = 1 - 4bh

I went to the movies and bought 4 tickets. It cost me 23 dollars for the tickets after I applied my 5 dollar Tuesday discount. Create an equation for this situation where x is cost of each ticket. How much did each ticket cost? (answer asap pls)
Answer:
x= 5.75$
Step-by-step explanation:
23 divided by 4 = 5.75$ (without the discount it is 10.75$)
Answer:
each ticket=$7.
x=7
Step-by-step explanation:
The total price of your tickets AFTER applying your $5 discount was 23.
Therefore, the price of 4 tickets would be 23+5, aka 28.
We can first begin with,
4x-5=23
4x=23+5
4x=28
x=7.

Solve for B
A=3B+4C
B=?
Answer:

Find x if the base angles of an isosceles triangle are 61 degrees and 7x+19.
The question provides the measures of two angles, (one of which contains
a variable), and the relationship between the angles.
The value of x is 6 degrees
Reason:
The given parameters are;
The base angles of the isosceles triangles are; 61° and (7·x + 19)°
Required:
To find the value of x
Solution:
By definition of an isosceles triangle, we have;
The base angles of an isosceles triangle are equal, therefore;
(7·x + 19) = 61
Which gives;
[tex]x = \dfrac{61 - 19}{7} = 6[/tex]
The value of x = 6

Answer:
9.5km/hr and 16.667m/s
Step-by-step explanation:
velocity = Distance / Time
v = 19/2 --> v = 9.5km/hr
