The answer for this should be 50 but I don’t know how could someone tell me why it’s $50?

Answer:

150 miles

Step-by-step explanation:

In this problem, we are only interested in the distance that Lauren drove, this means that her average speed (75 mph to the cost, and 25 mph on the way back) does not matter since the distance remains the same. If one leg of trip is 75 miles long, the total mileage for the round trip is:

[tex]M=75+75\\M=150\ miles[/tex]

Lauren drove 150 miles.

Subtracting [tex]2x[/tex] from both sides gives us the false statement [tex]2=3,[/tex] so this equation can never be true and thus has no solutions.

Good luck on your assignment..

The quotient obtained by dividing the expression (3x³+10x²+10x+4) divided by (x+2) is 3x²+4x+2

A division is a process of splitting a specific amount into equal parts.

We are asked to find the quotient obtained by dividing the expression

(3x³+10x²+10x+4) divided by (x+2)

We can also write this expression as i.e. we are asked to find the value of the expression:

3x³+10x²+10x+4/x+2

We can write the expression on the numerator as:

3x³+10x²+10x+4=(3x²+4x+2)(x+2)

Divide both sides by x+2

3x³+10x²+10x+4/x+2=3x²+4x+2(x+2)/x+2

3x³+10x²+10x+4/(x+2)=3x²+4x+2

Hence, the quotient obtained by dividing the expression (3x³+10x²+10x+4) divided by (x+2) is 3x²+4x+2

Answer:

(3x +4)²

Step-by-step explanation:

I think of a number x, then i multiply it by 3, add 4 and square the result.

Representing this mathematically,

x * 3= 3x

Then add 4 which will be 3x + 4

Squaring the result would be (3x +4)².

So, if we give our unknown which is x the value of say, 3.

Substituting the value of x into that equation would be easy.

(3 (3) +4)²

= (9 + 4)²

= (11)²

=132.

Step-by-step explanation:

a) Let 'm' represents score in a Mathematics test. The variable has a fixed value because the marks Sarah obtained in her test will not change

b) Let 'd' represent the distance between the Zen house and the school. The variable has a fixed value because by using the same route, the distance will always remain constant.

c) Let 't' represent the temperature on the summit of Mount Everest. The variable has a changed value because the temperature may alter depending on the time of day and also climatic conditions which will affect the temperature.

Answer:

214 ft^3

Step-by-step explanation:

Here, we are asked to calculate the volume of the cylindrical construction pipe.

Mathematically, the volume V

V = pi * r^2 * h

r is radius = diameter/2 = 4/2 = 2 ft

h = 17ft

pi = 3.14

Putting these values, we have;

V = 3.14 * 2^2 * 17 = 213.52 which is 214 ft^3 to the nearest whole number

Answer:

[tex]x = 26.25[/tex] inches

Step-by-step explanation:

Since we know the triangles are similar, we can simply set up ratios to find the length of side length 'x'.

[tex]\frac{15.75}{x} = \frac{9}{15}[/tex]

Cross multiply:

[tex]236.25 = 9x[/tex]

Divide both sides by '9' to solve for 'x':

[tex]\frac{236.25}{9} = \frac{9x}{9}[/tex]

[tex]x = 26.25[/tex]

Therefore, side length 'x' equals 26.25 in.

(a) Increased by 100%

(b) Increased by 50%

(c) Decreased by 33.33%

(d) Decreased by 50%

(e) Increased by 200%

(f) Decreased by 66.67%

Step-by-step explanation:

To calculate percentage change, we can use the following formula:

[tex]\text{Percentage Change =} \dfrac{\text{New value - Old Value}}{\text{Old Value}} \times 100[/tex]

Positive value of percentage change means increase and

Negative value of percentage change means decrease.

Solution a)

Old Value = 1

New Value = 2

[tex]\text{Percentage Change =} \dfrac{\text{2 - 1}}{\text{1}} \times 100\\\Rightarrow 100\%[/tex]

Increase of 100%

Solution b)

Old Value = 2

New Value = 3

[tex]\text{Percentage Change =} \dfrac{\text{3 - 2}}{\text{2}} \times 100\\\Rightarrow 50\%[/tex]

Increase of 50%.

Solution c)

Old Value = 3

New Value = 2

[tex]\text{Percentage Change =} \dfrac{\text{2 - 3}}{\text{3}} \times 100\\\Rightarrow -33.33\%[/tex]

Decrease of 33.33%.

Solution d)

Old Value = 2

New Value = 1

[tex]\text{Percentage Change =} \dfrac{\text{1 - 2}}{\text{2}} \times 100\\\Rightarrow -50\%[/tex]

Decrease of 50%.

Solution e)

Old Value = 1

New Value = 3

[tex]\text{Percentage Change =} \dfrac{\text{3 - 1}}{\text{1}} \times 100\\\Rightarrow 200\%[/tex]

Increase of 200%.

Solution f)

Old Value = 3

New Value = 1

[tex]\text{Percentage Change =} \dfrac{\text{1 - 3}}{\text{3}} \times 100\\\Rightarrow -66.67\%[/tex]

Decrease of 66.67%.

So, the answer is:

(a) Increased by 100%

(b) Increased by 50%

(c) Decreased by 33.33%

(d) Decreased by 50%

(e) Increased by 200%

(f) Decreased by 66.67%

Answer:

4096

Step-by-step explanation:

Lets start by applying a basic exponent rule. (a*b)^n is equal to a^n * b^n

Therefore,

((9(3/16)^-2)^3/2 = 9^3/2 * ((3/16)^-2)^3/2

Now lets focus on ((3/16)^-2)^3/2

(3/16)^-2 = 1/(3/16)^2 = (16^2/3^2)^3/2.

We can quickly eliminate the fractional exponent by plugging it into the numerator and the denominator and we get, 16^3/3^3 = 4096/27

So now we have, 9^3/2 * 4096/27

We can easily compute 9^3/2, which is (sqrt(9))^3, which is equal to 27.

Therefore, you have, 27*4096/27. The 27 cancels to give us a final answer of 4096

Notice that she already painted one face of each cube, that is, 8 faces in total, and she used 24 grams for that.

Now, there remain 3 faces per cube to be painted, which means there are 24 faces.

Then, we use the rule of three, if she used 24 grams of paint for 8 faces, how much grams of paint she would need to paint 24 faces?

[tex]24 \times \frac{24}{8}= 72 \ grams[/tex]

Answer:

3 miles

Step-by-step explanation:

First, we find the rate at which she drives, that is her speed.

Speed is given as:

speed = distance / time

When Cara drives to work, it takes her 30 minutes to drive 15 miles. Her speed is:

s = 15 / 30 = 0.5 miles per minute.

She drives at the same rate to The Dreamy Donut Shop and it takes her 6 minutes.

From the formula of speed, distance is given as:

distance = speed * time

Therefore, the distance of The Dreamy Donut Shop is:

distance = 0.5 * 6 = 3 miles

The Dreamy Donut Shop is 3 miles away.
