The volume of a given piece of aluminum is 92.6 mL.

Given: A piece of Aluminum.

Mass = 250 g

Density = 2.7 g/mL

We need to find the volume.

We know, density is given by:

⇒ Density = Mass / Volume

⇒ Volume = Mass / Density

⇒ Volume = 250/2.7

⇒ Volume = 92.6 mL

Therefore, the volume of the piece of aluminum is 92.6 mL.

Step-by-step explanation:

Answer:  8 yds³ 22ft³ 1712 in³

Step-by-step explanation:

9 yds³ + 113 in³ - (4 ft³ + 129 in³)

Understand that you need to "borrow" 1 yd³ and convert it into ft³ and then "borrow" 1 ft³ and convert it into in³

Conversions:

[tex]1 yd^3\times \bigg(\dfrac{3ft}{1yd}\bigg)^3=\large\boxed{27ft^3}\\\\\\1ft\times\bigg(\dfrac{12in}{1ft}\bigg)^3=\large\boxed{1728in^3}[/tex]

The given equation:

   9 yds³ +  0 ft³    + 113 in³          

                - 4 ft³   - 129 in³

Borrow 1 yd³ to create 27 ft³:

= 8 yds³  + 27 ft³ + 113 in³

               -   4 ft³  - 129 in³

Borrow 1 ft³ to create 1728 in³:

= 8 yds³  + 26 ft³ + 1841 in³

               -   4 ft³  -  129 in³

= 8 yds³  + 22 ft³ + 1712 in³

Answer:

1+i

Step-by-step explanation:

The explicit formula for the compound interest geometric tell us: If P1 is invested at an interest rate of i per year, compounded annually, the future value Pn at the end of the nth year is:

[tex]Pn=P1(1+i)^{(n-1)}[/tex]

For example if you have $10 at 5% at an interest rate of 5% per year.

Then if you want to know the amount of money at the end of the 2, 3 and 4 year, you have:

n=1 year P1=10

n=2 year

[tex]P2=10(1+(5/100))[/tex]

[tex]P2=10(1+(5/100))^{(2-1)}[/tex]

[tex]P2=10(1+(5/100))^{(1)}[/tex]=10,5

n=3 year

[tex]P3=10(1+(5/100))*(1+(5/100))[/tex]

[tex]P3=10(1+(5/100))^{(3-1)}[/tex]

[tex]P3=10(1+(5/100))^{(2)}[/tex]=11.025

n=4 year

[tex]P4=10(1+(5/100))*(1+(5/100))*(1+(5/100)) [/tex]

[tex]P4=10(1+(5/100))^{(4-1)}[/tex]

Step-by-step explanation:

we know that

A circle can be circumscribed about any regular polygon

A circumscribed circle surrounds a regular polygon, touching every vertex

For this case we must solve the following equation:

[tex]\frac {5} {6} x = \frac {10} {3}[/tex]

Multiplying by "6" on both sides of the equation we have:

[tex]5x = \frac {10 * 6} {3}\\5x = \frac {60} {3}\\5x = 20[/tex]

Dividing between 5 on both sides of the equation we have:

[tex]x = \frac {20} {5}\\x = 4[/tex]

So, the solution is [tex]x = 4[/tex]

Answer:

Option D

Answer: LAST OPTION.

Step-by-step explanation:

In order to solve for the variable "x" from the expression [tex]\frac{5}{6}x=\frac{10}{3}[/tex], you need to follow these steps:

1) You need to multiply both sides of the equation by 3:

[tex]3(\frac{5}{6}x)=(\frac{10}{3})(3)\\\\\frac{15}{6}x=10[/tex]

2)  You need to multiply both sides of the equation by 6:

[tex](6)(\frac{15}{6}x)=(10)(6)\\\\15x=60[/tex]

3) Finally, you can divide both sides of the equation by 15:

[tex]\frac{15x}{15}=\frac{60}{15}\\\\x=4[/tex]

Answer:

$3400 after one year

$17400 after the 36 months

Step-by-step explanation:

3000+400*1=3400

3000+400*36=17400

After a year, $7,800 will have been spent on the car. The final cost of the car will be $16,800.

i) To find out how much money will have been spent after a year, we need to substitute the value of M with 12 (since there are 12 months in a year) in the formula S = 3000 + 400M. Therefore, S = 3000 + 400 × 12 = $7,800.

ii) The final cost of the car can be found by substituting the value of M with 36 (since there are 36 months of payments) in the same formula. Therefore, S = 3000 + 400 ×36 = $16,800.

Answer:

y = [tex]\frac{1}{4}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{4}[/tex] x - 1 ← is in this form

with slope m = [tex]\frac{1}{4}[/tex]

• Parallel lines have equal slopes, thus

y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation of the parallel line

To find c substitute (8, 5) into the partial equation

5 = 2 + c ⇒ c = 5 - 2 = 3

y = [tex]\frac{1}{4}[/tex] x + 3 ← equation of parallel line

Answer: What is the blood type of each person at the clinic?

let [tex]log_{4}[/tex] 256 = n, then

256 = [tex]4^{n}[/tex]

Note that 256 = [tex]4^{4}[/tex], hence

Answer:

75 cm^2

Step-by-step explanation:

We have the lengths of two corresponding sides. The scale factor from the large triangle to the small triangle is 16/64 = 1/4. Each side of the smaller triangle is 1/4 times the length of the corresponding side of the large triangle.

For the areas, the scale factor is the square of the scale factor of the lengths. Area scale factor = 1/4^2 = 1/16.

The area of the small triangle is 1/16 the area of the large triangle.

area of small triangle = (area of large triangle) * (area scale factor)

area of small triangle = 1200 cm^2 * 1/6 = 1200 cm^2/16

area of small triangle = (1200 cm^2)/16 = 75 cm^2

Answer:

I would say 75cm^2.

Answer:

Explanation:

Area of Triangle = 1/2(B*H)

To convert 25/38 to a percentage, divide 25 by 38, multiply by 100, and round to the nearest tenth, resulting in 65.8%.

To convert 25/38 to a percentage, you divide 25 by 38 and then multiply the result by 100.

The calculation would look like this:

Divide 25 by 38: 25 ÷ 38 = 0.6578947368

Multiply the result by 100 to get the percentage: 0.6578947368 × 100 = 65.78947368%

Round the result to the nearest tenth of a percent: 65.8%

Therefore, 25/38 as a percentage rounded to the nearest tenth of a percent is 65.8%.

Final answer:

To express 25/38 as a percentage, divide 25 by 38 and then multiply the result by 100. The answer is approximately 65.8%.

Explanation:

To express 25/38 as a percentage, you can divide 25 by 38 and then multiply the result by 100.

25 ÷ 38 ≈ 0.6578947368421053

0.6578947368421053 × 100 ≈ 65.8

Therefore, 25/38 as a percentage, rounded to the nearest tenth of a percent, is approximately 65.8%.

Final answer:

The dealer's cost for the car is $15,851.65 and the sticker price is $20,636.

Explanation:

To find the sticker price and dealer's cost for the car, we need to calculate the prices of the base price, options, and destination charges.

First, calculate the dealer's cost for the base price by multiplying 85% of the base price: $18,649 x 0.85 = $15,851.65.

Next, calculate the dealer's cost for the options by multiplying 70% of each option cost and summing them up: $453 x 0.70 + $612 x 0.70 + $386 x 0.70 + $290 x 0.70 = $845.20.

Finally, calculate the sticker price by adding the base price, options, and destination charges: $18,649 + $453 + $612 + $386 + $290 + $246 = $20,636.

Therefore, the dealer's cost is $15,851.65 and the sticker price is $20,636.

Answer:

The constant term is the area of weight room.

Step-by-step explanation:

A rectangular gym has an area of [tex]4x^2[/tex]  square feet

The school decides to add a new  weight room.

The total area of the gym and the weight room is [tex](4x^2+480)[/tex] ft^2.

Here, 480 is the area of the weight room because [tex]4x^2[/tex] is the area of gym and the total area will be addition of both the areas.

Hence, the constant term is the area of weight room.

The area of the weight room is 480 square ft and the constant term 480 represents the area of the weight room.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

The area of the rectangular gym = 4x² square ft

The total area of the gym and the weight room = (4x² + 480) square ft

Let A be the area of the weight room:

Total area = area of gym + area of weight room

4x² + 480 = 4x² + A

A = 480 square ft

Thus, the area of the weight room is 480 square ft and the constant term represents the area of the weight room.

Answer:

x =-2 and z =-4

Step-by-step explanation:

We need to solve the following systems of equation

-3x-2y+4z = -16       eq(1)

10x+10y-5z = 30      eq(2)

5x+7y+8z = -21        eq(3)

Multiply eq(1) with 10 and eq(2) with 3

-30x-20y+40z = -160

30x+30y-15z = 90

__________________

10y+25z = -70

Divide by 10

2y+5z = -14      eq(4)

Multiply eq(1) with 10 and eq(3) with 6

-30x-20y+40z = -160

30x+42y+48z = -126

__________________

22y+88z = -286

Divide by 11

2y+8z = -26     eq(5)

Subtract eq(4) and eq(5)

2y+5z = -14  

2y+8z = -26      

-    -        +

__________

-3z = 12

z = 12/-3  

z = -4

Putting value of z in eq(4)

2y+5z = -14  

2y +5(-4) = -14

2y = -14 +20

2y = 6

y = 3

Putting value of z and y in eq(1)

-3x-2y+4z = -16

-3x-2(3)+4(-4) = -16

-3x -6 -16 = -16

-3x = -16+16+6

-3x = 6

x = 6/-3

x = -2

x = 3

Step-by-step explanation:

3(x + 2) = 6(x - 1) + 3

Divide both sides by 3.

x + 2 = 2(x - 1) + 1

Distribute the 2 on the right side.

x + 2 = 2x - 2 + 1

Combine like terms on the right side.

x + 2 = 2x - 1

Add 1 to both sides. Subtract x from both sides.
