When 4((0.5 x + 2.5 y minus 0.7 x minus 1.3 y + 4)) is simplified, what is the resulting expression?

Answers

Answer 1

Answer:

[tex]-0.8x + 4.8y + 16[/tex]          

Step-by-step explanation:

We have to simplify the given expression:

[tex]4(0.5x + 2.5y-0.7x-1.3y+4)[/tex]

First we group all the like terms of x.

[tex]4((0.5x-0.7x) + 2.5y-1.3y+4))\\=4(-0.2x+ 2.5y-1.3y+4)[/tex]

Next we group all the like terms of y.

[tex]4(-0.2x+ (2.5y-1.3y)+4)\\=4(-0.2x+1.2y+4)[/tex]

Now, we use distributive property for the multiplication,

[tex]4(-0.2x+1.2y+4)\\=(4\times -0.2x) + (4\times 1.2y) + (4\times 4)\\=-0.8x + 4.8y + 16[/tex]

is the required simplified expression.

The walking track at one fitness center is a 2/5 mile loop. If Kara walks around the track 8 1/2 times, how many miles does Kara walk? A 3 2/5 miles B 4/85 miles C 8 9/10 miles D 21 1/4 miles

Answers

Kara walks A. 3 2/5 miles

Step-by-step explanation:

Step 1; We must calculate how much 2/5 miles is. 2/5 miles equals 0.40 miles. Kara walks this distance times 8 1/2. 8 1/2 times equals 8.5 times. So the distance she walked is the number of loops walked × distance of each loop.

Total distance walked = Number of loops walked × distance of each loop

                                      = 8.5 loops × 0.20 miles = 3.4 miles

Step 2; In order to check which option this is, we must know what values all the given options are equal to

A. 3 2/5 miles equals 3 miles + 2/5 miles = 3 + 0.20 = 3.20 miles.

B 4/85 miles equals 0.047 miles which is lesser than one loops distance.

C. 8 9/10 miles equals 8 miles + 9/10 miles = 8 + 0.90 = 8.90 miles

D. 21 1/4 miles equals 21 miles + 1/4 miles = 21 + 0.25 = 21.25 miles.

So the answer is option A.

d.46
Show your work below!!!

Answers

Answer: b.14

Step-by-step explanation:

We have two shelves, the top shelf [tex]s_{t}[/tex] and the bottom shelf [tex]s_{b}[/tex].

Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:

[tex]s_{t}=10+\frac{1}{3}s_{b}[/tex] (1)

Then, we are told there are 12 books on the bottom shelf:

[tex]s_{b}=12[/tex] (2)

Substituting (2) in (1):

[tex]s_{t}=10+\frac{1}{3}(12)[/tex] (3)

[tex]s_{t}=10+\frac{12}{3}[/tex] (4)

[tex]s_{t}=14[/tex] (5) This is the number of books on the top shelf

Hence, the correct option is b.

Answer:

A on E2020 (x = -5, x = 2, y = 3)

Step-by-step explanation:

By looking at the equation, we know that the horizontal asymptote can be found by using [tex]y=\frac{a}{b}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the leading coefficients of the variables in the numerator and denominator.

In the equation, [tex]a=3[/tex] and [tex]b=1[/tex]. So, the horizontal asymptote is 3, meaning [tex]y=3[/tex].

To find the vertical asymptotes, we must simplify the denominator by factoring. We will then get [tex](x+5)(x-2)[/tex] in the denominator. So, [tex]x=-5[/tex] and [tex]x=2[/tex].

After every score in a sample is multiplied by 5, the mean is found to be M = 40. What was the value for the original mean?

Answers

Answer:

M=8

Step-by-step explanation:

We have that every score in a sample is multiplied by 5, and the mean is found to be M = 40.

We want to find the original mean.

Since each of the data value is multiplied by 5, the new mean will be 5 times the original mean.

To get the original mean, we need to divide by 5;

Therefore the original mean is [tex]\frac{40}{5}=8[/tex]

Final answer:

To find the original mean, divide the new mean by the multiplying factor.

Explanation:

To find the original mean, we need to undo the multiplication by dividing the new mean by the multiplying factor. Since every score was multiplied by 5, we divide the new mean by 5 to get the original mean.

Original Mean = New Mean / Multiplying factor

Negative 5 y minus 4 = negative (x + 3) squared minus one-half
y = negative 3 plus-or-minus StartRoot 5 x + seven-halves EndRoot

Answers

Answer:

The correct option is the last option d.) y = negative 3 plus-or-minus StartRoot 5 x + seven-halves EndRoot

Step-by-step explanation:

the given equation is [tex]5y + 4 =(x+3)^{2} + \frac{1}{2}[/tex]

Therefore we can write [tex]5y\hspace{0.1cm} = (x+3)^{2} + \frac{1}{2} - 4 \hspace{0.3cm} \Rightarrow \hspace{0.2cm} 5y = (x+3)^{2} - \frac{7}{2} \hspace{0.3cm} \Rightarrow \hspace{0.3cm} y = \frac{(x+3)^{2}}{5} - \frac{7}{10}[/tex]

To find the inverse of the above function let us replace x with y and y with x.

Therefore we get

[tex]x = \frac{(y+3)^{2}}{5} - \frac{7}{10}[/tex]

Now we write the above equation with only y on the Left hand side and we will obtain the inverse of the given function

[tex]y = \pm \sqrt{5 (x + \frac{7}{10} )} \hspace{0.1cm} - \hspace{0.1cm} 3 \hspace{0.1cm} \Rightarrow\hspace{0.1cm} y = \pm \sqrt{5x + \frac{7}{2} } - \hspace{0.1cm} 3 \hspace{0.1cm}[/tex]

Nine times a number y subtracted from 95 equals 37

Answers

Answer:

y = 6.44

Step-by-step explanation:

"nine times number y" : 9y

"subtracted from 95" : (95 - 9y)

"equals 37" : (95 - 9y) = 37

solving for y

95 - 9y = 37   (subtract 95 from both sides)

-9y = 37 - 95

-9y = -58  (divide both sides by -9)

y = -58/ -9

y = 6.44

Step-by-step explanation:

Speed = distance/time

Speed at 160miles in 3.2hrs will be = 160/3.2= 50

At the constant speed of 50, time taken to travel 300miles

what is the volume of a hemisphere with a radius of 2.3m round to the nearest tenth of a cubic meter

Answers

Answer: [tex]25.5 m^{3}[/tex]

Step-by-step explanation:

If the volume of a sphere is

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

Where [tex]r=2.3 m[/tex] is the radius

The volume of a hemisphere is half the volume of the total sphere:

[tex]V_{hemisphere}=\frac{V}{2}=\frac{\frac{4}{3} \pi r^{3}}{2}[/tex]

[tex]V_{hemisphere}=\frac{2}{3} \pi r^{3}[/tex]

Solving this equation:

[tex]V_{hemisphere}=\frac{2}{3} \pi (2.3 m)^{3}[/tex]

Finally:

[tex]V_{hemisphere}=25.48m^{3} \approx 25.5 m^{3}[/tex]

The volume is approximately 12.8 cubic meters.

To find the volume of a hemisphere, we can use the formula for the volume of a sphere and then take half of that volume.

The formula for the volume of a sphere is:

V = (4/3)πr³

Since we only need the volume of a hemisphere, we'll divide by 2:

V = (1/2) * (4/3)πr³

Given the radius (r) is 2.3 meters, we substitute the value into the formula:

V = (1/2) * (4/3)π (2.3)³

First, calculate the cube of the radius:

2.33 = 2.3 * 2.3 * 2.3 = 12.167

Next, plug this back into the formula:

V = (1/2) * (4/3)π * 12.167

Then, calculate the constant part of this equation:

(4/3)π ≈ 4.18879

So:

V = (1/2) * 4.18879 * 12.167 = 25.5288

Finally, divide by 2:

V ≈ 12.7644

Rounding to the nearest tenth, the volume of the hemisphere is 12.8 cubic meters.
