Answer:
I believe it would be 90
Step-by-step explanation:
The required age of Mollie's is 32years and age of Heather's is 72years.
Given that,
The ratio of Mollie’s age to Heather’s age is 4:9,
Heather is 40 years older than Mollie.
We have to determine,
How old is Mollie.
According to the question,
The ratio of Mollie’s age to Heather’s age is 4:9,
The age of Mollie's = 4x
And age of Heather's = 9x
Then ,
The age of Mollie is calculated in the following steps.
The difference between the age of both is 40 years
Age of Heather's - Age of Mollie = Difference of their ages
Then,
[tex]= 9x-4x = 40\\\\= 5x = 40\\\\= x = \frac{40}{5} \\\\= x = 8[/tex]
The value of x is 8.
Therefore,
Age of Mollie's = 4x = (4).(8) = 32years
And Age of Heather's = 9x = (9).(8) = 72years
Hence, The required age of Mollie's is 32years and age of Heather's is 72years.

Solve the equation
3x+1+10x=x+4
Answer:
x=¼
Step-by-step explanation:
3x+1+10x=x+4 (Group like terms )
3x+10x-x=4-1
12x=3(Divide both sides by 12)
[tex] \frac{12x}{12} = \frac{3}{12} [/tex]

How much charge is needed to repel another charge of 9.9 x 10^-6 N when they are 200m apart? Please help meee I really can't understand Coulomb's Law : (
Answer:
The charge needed will be [tex]q=6.6\: \mu C[/tex]
Step-by-step explanation:
The equation of the electric force is given by:
[tex]F=k\frac{qQ}{r^{2}}[/tex]
We have the force [tex]F = 9.9 10^{-6}\: N[/tex] and the distance r = 200. k is the Coulomb constant. Q and q are the charges.
We assume we have the same charge of the particles, so we have:
[tex]q^{2}=\frac{Fr^{2}}{k}[/tex]
[tex]q^{2}=\frac{9.9*10^{-6}200^{2}}{9*10^{9}}[/tex]
[tex]q=6.6*10^{-6}\: C[/tex]
Therefore, the charge needed will be [tex]q=6.6\: \mu C[/tex]

Answer:
(f o g)(x) = 4x^2 - 8
Step-by-step explanation:
(f o g)(x) = f(g(x))
f(x) = x^2 - 8
g(x) = 2x
f(g(x))
f(2x) = (2x)^2 - 8
= 4x^2 - 8
(f o g)(x) = 4x^2 - 8

In continuous type of series, for finding mean, which amongst the
following is considered as X variable value?
Select one:
O a lower limit of the interval
O b. upper limit of the interval
O c. mid point of the interval
O d. none of these
In the continuous type of series for determining the mean, the midpoint of the interval should be considered as the X variable value.
Continuous Series is the series where all types of class intervals with the frequency should be listed in the table form. Here all the class intervals do not contain a similar frequency.
For determining the mean, the direct method should be used in which the midpoint from X should be measured and the same should be relevant.
So, the following should not be relevant for determining the mean:
The lower limit and upper limit of the interval.Therefore In the continuous type of series for determining the mean, the midpoint of the interval should be considered as X variable value.

Find: m∠1, m∠2, and m∠5 in degrees
Answer:
<1 = 100
<2 = 80
Step-by-step explanation:
Angle 1 and angle 2 are supplementary
Supplementary angles add to 180 degrees
<1 + <2 = 180
The angles are in a ratio of 5 to 4
Multiply by x to get the measure of each angle
<1 = 5x <2 = 4x
5x+4x = 180
Combine like terms
9x = 180
Divide by 9
9x/9 =180/9
x =20
<1 = 5x = 5*20 = 100
<2 = 4x = 4*20 = 80
Answer:
