Simplify the radical expression 3√5+6√45
Answer:
21[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplifying [tex]\sqrt{45}[/tex]
= [tex]\sqrt{9(5)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{5}[/tex] = 3[tex]\sqrt{5}[/tex]
Then
3[tex]\sqrt{5}[/tex] + 6[tex]\sqrt{45}[/tex]
= 3[tex]\sqrt{5}[/tex] + 6(3[tex]\sqrt{5}[/tex] )
= 3[tex]\sqrt{5}[/tex] + 18[tex]\sqrt{5}[/tex]
= 21[tex]\sqrt{5}[/tex]
Answer:
[tex]21\sqrt{5}[/tex]

The rule for a pattern is ''take half the number to get the next number.'' the first number in the pattern is 16 what is the next number?
Answer:
8
Step-by-step explanation:
Let the next number be x
'taking half the number to get the next number. is expressed as;
1/2 of 16 = x
x = 1/2 *16
x = 16/2
x = 8
hence the next number will be 8

Theresa had her hair cut to a length of 10 inches. If her hair grows at a rate of 0.02 inch per day, which equation represents the length (L) of Theresa’s hair, in inches, after d days?
d=0.2+10Ld is equal to 0 point 2 plus 10 liters
d=10+0.2Ld is equal to 10 plus 0 point 2 liters
L=0.2+10dcap l is equal to 0 point 2 plus 10 d
L=10+0.2dcap l is equal to 10 plus 0 point 2 d
Answer:
L = 0.02d + 10
Step-by-step explanation:
The hair starts at 10 inches long.
L = 10
Now we add 0.02 inches in length per day.
In 1 day, it grows 0.02 inches.
In 2 days, it grows 0.02 * 2 inches.
In d days, it grows 0.02d inches.
Now we add the starting length, 10, and the growth per day, 0.02d, to get:
L = 0.02d + 10
find the ratio of 2500g to 35kg
35kg - 3500g
3500g - 2500g
= 1000g
Answer:
1 : 14
Step-by-step explanation:
The measures must have the same units, that is both g or Kg
2500 g : 35 Kg
= 2500 g : 35000 g ( 1 Kg = 1000 g )
Divide both parts by 100
= 25 : 350 ( divide both parts by 25 )
= 1 : 14

What is the image of the point (2,-3) after a rotation of 90 ∘ counterclockwise about the origin?
Answer:
(2,-3) changes to (3,2)
A is correct.
Step-by-step explanation:
Given: The point (2, −3) after a counterclockwise rotation of 90° about the origin.
Rotation is counterclockwise about origin.
We are given coordinate
We can see in diagram also. Please see the attachment for rotation.
Hence, (2,-3) changes to (3,2
If the data (x+1), (2x+1), (x+7), and (3x+4) are in ascending order and the median is 16, then find the value of 'X'.
Answer:
[tex]sum \: = (x + 1) + (2x + 1) + (x + 7) + (3x + 4) \\ = 7x + 13 \\ median = ( \frac{sum}{2} + 1) \\ 16 = ( \frac{7x + 13}{2} + 1) \\ 7x + 13 = 14 \\ 7x = 1 \\ x = \frac{1}{7} [/tex]

so 90 meet 5
30 meet 5/2=2.5
and 60 meet 2.5√3
so the answer is 2.5
Answer:
2.5
Step-by-step explanation:
[tex]\sin 30\degree = \frac{x}{5}\\\therefore x = 5\sin 30\degree\\\therefore x = 5 \times \frac{1}{2}\\\therefore x = 2.5[/tex]

Trisha's favourite song is 2 1/2 minutes. There is a drum solo that begins one third of the way into the song and last for 24 seconds. How many seconds does the drum solo end
Answer:
74 seconds or1 minute 14 secondsStep-by-step explanation:
The drum solo begins a third of the way into the song which lasts 2.5 minutes.
The drum solo therefore starts at:
= 2.5 * 1/3
= 0.83 minutes
Translate that to seconds by multiplying by 60:
= 0.83 * 60
= 50 seconds
Solo begins at 50 seconds in and lasts for 24 seconds:
= 50 + 24
= 74 seconds or
= 1 minute 14 seconds

Solve for a side in right triangles
I don’t know how to do this so please someone teach me how to do this?? I need help here!
Answer:
2.33
Step-by-step explanation:
imagine a circle. its center is A, and it goes through B, so its radius is AB.
then it is important to know that the sum of all the angles in a triangle is 180 degrees.
one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.
more back to our circle.
in this circle the line CB is the sine of the angle at A multiplied by the radius.
and AC is the cosine of the angle at A multiplied by the radius.
we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).
=> CB = sin(A)×AB
AC = cos(A)×AB
=> 5 = sin(65)×AB
=> AB = 5 / sin(65)
=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =
= 5 × cot(65) = 2.33
