Answer:
The radius of a similar circle with center (-2, 0) has a length of 10 units.
Step-by-step explanation:
The radius of the new circle ([tex]R[/tex]) is the product of the former radius ([tex]r[/tex]) and the scale factor ([tex]k[/tex]), that is to say:
[tex]R = k\cdot r[/tex] (1)
If we know that [tex]k = \frac{5}{2}[/tex] and [tex]r = 4[/tex], then the radius of the new circle is:
[tex]R = k\cdot r[/tex]
[tex]R = \left(\frac{5}{2} \right)\cdot (4)[/tex]
[tex]R = 10[/tex]
The radius of a similar circle with center (-2, 0) has a length of 10 units.

A glass is 2/3 full. Then 40cm^3 of orange juice is poured in. The glass is now 4/5 full What is the total volume of the glass?
Answer:
The total volume of the glass is 300 cm^3.
Step-by-step explanation:
Let V represent the total glass volume.
Then (4/5)V - (2/3)V = 40 cm^3. The LCD here is 15, so we rewrite this equation as
(12/15)V - (10/15)V = 40 cm^3, or
(2/15)V = 40 cm^3.
Solve for V by multiplying both sides of this equation by (15/2):
(15/2)(2/15)V = (15/2)(40 = 300 cm^3
The total volume of the glass is 300 cm^3.

HELP me please
It is due in 10 minutes
Answer:
C, 8 hours
Why?
Because adding the given areas are 2 + 3 + 1 = 6 hours
Now we know that a given fact is that there are 60 minutes in 1 hour.
Let's add the minutes first, 45 + 45 + 30 = 120
120 divided by 60 = 2 hours
Now let's add ALL the areas:
6 hours + 2 hour = 8 hours.

How many 4 digit multiples can not be divided by 5
Answer:
1800
Step-by-step explanation:
Let us solve this question by Modular Airthmatic.
Let the lowest 4 digit number be X.
X= 1 (mod 5)
X =2 (mod 5)
X=3 (mod 5)
X =4 (mod 5)
X=1+5 t where t is any integer.
1+5 t=2 (mod 5)
5 t=1 (mod 5 )
5 is the Modular Inverse of modulo 5
t=1 (mod 5)
t =1+5 u : u= any integer.
X becomes 1+ 5 (1+5u )=6+25 u
6+25u =3 (mod 5)
25 u= -3 (mod 5)=2 (mod 5)
25 is Modular Inverse of Modulo 5
u=2 (mod 5)
u =2+5 v : v= any integer.
X becomes 6 +25 (2+5 v)=56+125 v .
56 +125 v=4 (mod 5)
125 v=-52 (mod 5)=3 (mod 5)
125 is Modular Inverse of modulo 5
v = 3 (mod 5)
v =3 +5 w where w is any integer.
For lowest 4 digit number, take
w=200
X=1003 : Lowest 4 digit number.
Take w=201
X=208 : Next number.
For 4 digit largest number, take
w=1995
X= 9978 : Largest number.
No. of Numbers =(1995 - 200 )+1=1800 □Ans.

help pls, i'm stuck on this question
Answer:
∠x = 60°
Step-by-step explanation:
first:
∠a = 60° was given
the sides on each side of ∠a are equal so their opposite angles are equal also.
The sum of the interior angles of any triangle is 180°
The angles opposite ∠a are (180° - 60°)/2 = 60° each
Second:
∠b = 60° was given
so the angles opposite ∠b are also 60° each
Third:
the 2 angles opposite x are both 60° each because they are both vertical angles to 60°
That leaves ∠x to be 180° - 60° - 60° = 60°

Question 13
Find the area of the (gray) shaded region. (2 tangent circles inscribed in a rectangle):
20
Answer:
42.92 square
Step-by-step explanation:
The radius of the circles is 5m
So, area of 1 circle is π(5×5)=78.54 square
Two areas will (78.54+78.54)=157.08 square
Rectangles height is ( 5+5)=10m
Rectangles area is (10×20)=200 square
Shaded region=(200-157.08) square =42.92 square

car from its starting point?
Answer:
50 miles.
Step-by-step explanation:
You can visualize this as a triangle. the west route is one leg and the south route is the other. The distance from the starting point is the hypotenuse. 48^2+14^2=c^2, c=50.
