Answer:

The total number of weeks Michelle needs to save is 29.

Step-by-step explanation:

Michelle plans to save $1185 in a number of weeks to determine later.

In the first 7 weeks, she will save $45 each week for a total of

$45 * 7 = $315

In the next 8 weeks, she will save $30 each week for a total of:

$30 * 8 = $240

During these 15 weeks, she has saved

$315 + $240 = $555

She still has a remaining $1185 - $555 = $630 to save.

Those $630 will be saved in a number of weeks at $45 per week, thus the number of weeks is:

$630 / $45 = 14 weeks

Total weeks = 15 + 14 = 29

The total number of weeks Michelle needs to save is 29.

The ratio of the number of blue lights to total lights is 3:5

The total number of lights is 190

To solve the problem we need to have the ratios out first.

we have a ratio of blue to white lights as

3 : 2

The ratio of the number of blue lights to white lights would be

114 : x

Such that we would have

3:2 = 114:x

This would give us

[tex]\frac{3}{2 } =\frac{114}{x}[/tex]

We would have to solve for the  value of x

To do this we are to cross multiply

3*x = 114*2

3x = 228

x = 228 / 3

= 76

ratio = 3 + 2 = 5

3 : 5

The proportion that can be used to solve for t is given as 114 : 3 = 38

38 x 5 = 190

or 114 + 76 = 190

Step-by-step explanation:

RSM proves correct

The value of a given function is required.

So, the answer is (E)83.

The given function [tex]f(x)[/tex] is the sum of all prime numbers less than [tex]x[/tex].

The required function is [tex]f(86)-f(82)[/tex]

[tex]f(86)=2+3+5+7+11+13+17+19+23+29+31+37+41+43+47+53+59+61+67+71+73+79+83[/tex]

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

a) dV/dt = 5 cm³/s

The volume (V) of the bubble is:

[tex]V=\frac{4}{3} \pi r^3\\\\Differentiating\ with\ respect\ to \ time(t)\\\\\frac{d}{dt}(V)=4\pi r^2 \frac{dr}{dt} \\\\Substituting\ \frac{d}{dt}(V)=5\ cm^3/s \ and\ r = 10\ cm\\\\5 = 4\pi *10^2*\frac{dr}{dt}\\\\5=400\pi *\frac{dr}{dt}\\\\\frac{dr}{dt}=0.004\ cm/s[/tex]

b) The surface area of the sphere (A) is:

[tex]A=4\pi r^2\\\\Differentiating\ w.r.t.\ t:\\\\\frac{dA}{dt}= 8\pi r\frac{dr}{dt} \\\\r=10, dr/dt=0.004\\\\\frac{dA}{dt}= 8\pi *10*0.004\\\\\frac{dA}{dt}=1\ cm^2/s[/tex]

The rate at which the radius of the bubble is changing at that time is [tex]0.0125 \pi cm^2/s[/tex]

The rate at which the surface area of the bubble is changing at that time is [tex]\pi^2 cm^2/s[/tex]

The formula for calculating the volume of a sphere is expressed as;

[tex]V =\frac{4}{3} \pi r^3[/tex]

r is the radius of the sphere

Differentiating the volume with respect to time;

[tex]\frac{dV}{dt} = \frac{dV}{dr} \times \frac{dr}{dt} \\\frac{dV}{dt} = 4 \pi r^2\frac{dr}{dt}[/tex]

Given the following parameters

dV/dt = 5 cm^3/sec.

r = 10 cm

Substitute into the formula to get dr/dt

[tex]\frac{dV}{dt} = 4 \pi (10)^2 \times \frac{dr}{dt}\\5 = 400 \pi \times \frac{dr}{dt}\\ \frac{dr}{dt}=0.0125 \pi cm/s\\[/tex]

The surface area of the bubble is expressed as:

[tex]S = 4 \pi r^2\\\frac{dS}{dt} = \frac{dS}{dr}\times \frac{dr}{dt}\\ \frac{dS}{dt} =8 \pi r \times 0.0125 \pi\\ \frac{dS}{dt} =\pi ^2 cm^2/s[/tex]

Hence the rate at which the surface area of the bubble is changing at that time is [tex]\pi^2 cm^2/s[/tex]

Answer:

CAD = 128

Step-by-step explanation:

Answer:

B. 34º

Step-by-step explanation:

So we know that a straight line is equal to 180º and we already have to measure of angle 2. So to find the angle of measure 1, we just subtract 146 from 180.

180 - 146 = 34

So the measure of angle 1 is 34º.

Now, because of alternate exterior angles, we know that they would be the same. SO m∠7 = 34º

Answer:

Answer:

3.5

Step-by-step explanation:

1. 5.4% X 65

2. 5.4/100 x 65

3. 0.054 x 65

Answer =3.5

3.5 is approximately 5.4% of 65 rounding to the nearest tenth

To calculate 5.4 % of 65 and simplify the result to the nearest tenth, we can multiply 65 by 0.054.

65 * 0.054 = 3.51

Rounding this value to the nearest tenth, we find that 5.4 % of 65 is approximately 3.5.

Therefore, after rounding to the nearest tenth, 5.4 % of 65 simplifies to 3.5. This means that 3.5 is approximately 5.4 % of 65 rounding to the nearest tenth. It represents the amount you would get if you took 5.4 % of 65, rounded to one decimal place.

Answer:

Step-by-step explanation:

Vertical angles are congruent.

  8x = 2x +30

  6x = 30 . . . . . . subtract 2x

  x = 5 . . . . . . . . divide by 6

__

  60y -40 = 40y +20

  20y = 60 . . . . add 40-40y

  y = 3 . . . . . . . .divide by 20

_____

Check

The 'x' angles are 8x° = 8·5° = 40°.

The 'y' angles are (40y+20)° = (40·3+20)° = 140°.

The angles are supplementary, as they are supposed to be.

Perimeter = 2x length + 2x width.

2(2x+3) + 2(x-5) = 44

Simplify:

4x + 6 +2x -10 = 44

Combine like terms:

6x -4 = 44

Add 4 to both sides:

6x = 48

Divide both sides by 6:

X = 8

Now replace x with 8 in the equation for length:

2x + 3 = 2(8) +3 = 16 + 3 = 19 cm
