Answer 2
Answer:

[tex]\boxed{\boxed{\pink{\bf \dag Value \ of \ x \ is \ \dfrac{5}{12}}}}[/tex]

Step-by-step explanation:

A linear equation is given to us and we need to solve the equation by converting it into a equivalent equation that does not contain fractions . So the given equation is :-

[tex]\bf\implies \dfrac{3}{5}x + \dfrac{1}{2}=\dfrac{3}{4}[/tex]

Here the denominators of the fractions are 5 , 2 and 4. So LCM of 5 , 2 and 4 is , 20 .

So , Multiply whole equation by 20 .

[tex]\bf\implies 20 \bigg( \dfrac{3}{5}x + \dfrac{1}{2} \bigg) = 20 \times \dfrac{3}{4}\\\\\bf\implies 4\times 3x + 10 = 5\times 3 \\\\\bf\implies 12x + 10 = 15 \:\: \bigg\lgroup \blue{\bf Equivalent \ equation \ without \ fractions .}\bigg\rgroup [/tex]

Now let's solve this equation since we successfully converted it into a equivalent equation without fractions.

[tex]\bf \implies 12x + 10 = 15 \\\\\bf\implies 12x = 15-10 \\\\\bf\implies 12x = 5 \\\\\bf\implies\boxed{\red{\bf x =\dfrac{5}{12}}}[/tex]

Hence the value of x is 5/12 .

Answers

Given that,

Michael is leaving a 15% tip for his waitress.

To find,

What percent of the  original price will he pay.

Solution,

Let the original price was 100%.

When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

[tex]115\%=\dfrac{115}{100}\\\\=1.15[/tex]

or

[tex]\dfrac{115}{100}=\dfrac{23}{20}[/tex]

So, this is the required solution.

What is the approximate area of the circle shown below?
A. 251 in
B. 5027 in 2
C. 126 in2
D. 20,106 in?

Answers

Answer:

B. 5027 in²

Step-by-step explanation:

Area of a circle = π r²

where r = 80/2 = 40 in

plugin value of r=40in into the formula:

Area of a circle = π r²

                         = π (40)²

                         = 5027 in²

A factory process requires 3 steps to finish a product. The steps each have a mean completion time of μ=10 seconds and a standard deviation of σ=5 seconds. The time it takes to complete each step is independent from the other steps. Let T be the total completion time of the 3 steps on a randomly chosen product.
Find the mean of T.

Answers

Answer:

The mean of T is 10 seconds

Step-by-step explanation:

The given parameters are;

The mean completion time of each step, μ = 10 seconds

The standard deviation, σ = 5 seconds

Each step is independent from the other steps

The variable that represents the total completion time for the three steps = T

We have the mean of T, [tex]\overline T[/tex], given by the combined mean as follows;

[tex]\overline T = \dfrac{n_1 \cdot \overline x_1 + n_2 \cdot \overline x_2 + n_3 \cdot \overline x_3 }{n_1 + n_2 + n_3 }[/tex]

Where;

[tex]The \ mean \ completion \ time \ for \ each \ step \ is \ \overline x_1 = \overline x_2 = \overline x_3 = 10 \ seconds[/tex]

n₁ = n₂ = n₃ = 1, each step is taken only once, we have;

[tex]\overline T = \dfrac{1 \times 10 + 1 \times 10 + 1 \times 10 }{1 + 1 + 1 } = \dfrac{30}{3} = 10 \ seconds[/tex]

Therefore, the mean of T = 10 seconds

Using the normal distribution, it is found that the mean of T is of 30 seconds.

A normal distribution has two parameters: Mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex].

For n instances of a normal variable, the mean is [tex]n\mu[/tex] and the standard deviation is [tex]s = \sigma\sqrt{n}[/tex].

In this problem, the mean is [tex]\mu = 10[/tex] and the standard deviation is [tex]\sigma = 5[/tex].

For the total completion, there are 3 instances, hence [tex]n = 3, n\mu = 3(10) = 30[/tex], hence, the mean of T is of 30 seconds.

What goes on the lines I don’t understand the problem

Answers

Answer:

Step-by-step explanation:

a). Let the number of spoons = x

And number of forks = y

Total number of spoons and forks bought by Perry = 10

x + y = 10 --------(1)

Cost of one spoon = $5

Cost of one fork = $3

Therefore, total cost of x spoons and y forks = $(5x + 3y)

5x + 3y = 42 -------(2)

b). Now we can convert these equations into the slope-intercept form.

x + y = 10 ⇒ y = -x + 10

Table for input output values,

x        2         4          6          

y        8         6          4                

5x + 3y = 42

3y = -5x + 42

y = [tex]-\frac{5}{3}x+14[/tex]

x        0           3          6        

y       14           9          4                  

Point of intersection of these lines will be (6, 4).

Veronica wants to buy a new bicycle. The bicycle costs $310. Veronica
opened a savings account with $50. She also got a job and plans to
save $20 a week. How long will it take her to save up enough money
for the bike?

Answers

Step-by-step explanation:

bicycle cost= 310

initial money in savings account= 50

additional money saved per week = 20

number of weeks = w

you have to set up an equation

The equation is...

bicycle cost = additional money saved × w + initial money

Substitute the values

310 = 20w + 50

Solve for w

310 - 50 = 20w +50 - 50

260 = 20w

260÷ 20 = 20w÷ 20

13 = w

It will take 13 weeks for her to have enough money for her bicycle

At the instant when the radius of a cone is 3 inches, the volume of
the cone is increasing at the rate of 9 pi cubic inches per minute. If
the height is always 3 times the radius, find the rate of change of the
radius at that instant.

Answers

Answer:

The rate of change of the radius of the cone when the radius is 3 inches is 0.[tex]\overline 3[/tex] inch/minute

Step-by-step explanation:

The given parameters are;

The radius of the cone = 3 inches

dV/dt = 9·π in.³/min

The height, h = 3 × Radius, r

The formula for the volume of a cone, V is V = 1/3×π×r²×h = 1/3×π×r²×3×r = π·r³

Therefore, we have;

dV/dt = dV/dr × dr/dt

dV/dr =3·π·r²

∴ dr/dt = dV/dt/(dV/dr) = 9·π/(3·π·r²) = 3/r²

When r = 3 inches, we have;

dr/dt = 3/r² = 3/(3²) = 1/3 inch/minute

The rate of change of the radius of the cone when the radius is 3 inches = 0.[tex]\overline 3[/tex] inch/minute

What are the slope, m, and the y-intercept, B, of a line that pases through the points (-2,1)and (8,-5)?

B. m=-3/5 and b=-1/5
C. m=-3/5 and b=11/5
D. m=5/3 and b=13/3​

Answers

Answer:

B. m= -3/5 and b= -1/5

Step-by-step explanation:

Given points:

(-2, 1) and (8, -5)

Slope is:

m = (y2 - y1)/(x2 - x1)m = (-5 - 1)/(8 - (-2)) = -6/10 = -3/5m = -3/5

Use formula y = mx + b, substitute x = -2, y = 1, m = -3/5, find y-intercept b:

1 = (-3/5)*(-2) + b1 = 6/5 + bb = 1 - 6/5b = - 1/5

A 1.4 gallons
B 15 gallons
C 14 gallons
D 1.5 gallons
E 140 gallons

Answers

Answer:

B. 15 gallons

Step-by-step explanation:

We don't need an exact answer, so we estimate

To do this, we round

41 is a tens number, so I'm going to round to the nearest 10

40

612.9 is a hundreds number, so I'm rounding to the nearest hundred

600

for EACH gallon, the car drives(roughly) 40 miles. If I have driven(roughly) 600 miles, that means I have used 600/40=15 gallons

In triangle ABC below, BD is the altitude. Find the length of DC. Leave your answer in
simplified radical form.

Answers

Answer:

Step-by-step explanation:

Step 1: Find AB Use Pythagoras Theorem

AB = [tex]\sqrt{AC^{2} -BC^{2} } = \sqrt{12^{2} -8^{2} } = \sqrt{80}[/tex]

Step 2: Find the Area of the triangle ABC

Area = [tex]\frac{1}{2}AB.BC = \frac{1}{2}\sqrt{80}.8 = 4\sqrt{80}[/tex] = [tex]16\sqrt{5}[/tex]

Step 3: Find BD. Use the area of the triangle above

Area = [tex]\frac{1}{2}BD.AC[/tex]

We already known the Area and AC so, we just plug all the number in

BD = [tex]\frac{2. Area}{AC}[/tex] =  [tex]\frac{2.16\sqrt{5}}{12}[/tex] = [tex]\frac{8\sqrt{5}}{3}[/tex]

Step 4: Find DC. Use Pythagoras Theorem of the triangle BDC

DC = [tex]\sqrt{BC^{2}-BD^{2} }[/tex] = [tex]\sqrt{8^{2}-(\frac{8\sqrt{5}}{3})^{2}}[/tex] =  [tex]\frac{16}{3}[/tex]
