What is the density of lead if a cube measuring 2 cm per side has a mass of 90.8 g?

Answers

Answer:

8.1 g/cm

3

Explanation:

Density is equal to mass divided by volume. You are given a mass of  

64.7

grams. You can find the volume of the cube by doing height multiplied by width multiplied by depth.

Because all of the sides of a cube are the same length, the volume just ends up being  

2

3

.

(

2 cm

)

3

=

8 cm

3

Now plug both of those numbers into your density equation

ρ

=

m

V

=

64.7 g

8 cm

3

=

8.1 g/cm

3

Step-by-step explanation:

Answer:

8,1 g / cm

3

Explicación:

La densidad es igual a la masa dividida por el volumen. Se le da una masa de  

64,7

gramos. Puede encontrar el volumen del cubo multiplicando la altura por el ancho por la profundidad.

Como todos los lados de un cubo tienen la misma longitud, el volumen acaba siendo

So is it saying Friday plus Saturday

Answer:   66 2/3 %

 They asked for a mixed number percent, so there it is!  

Normally, round to 67%

Step-by-step explanation:

Get the total of all the days 5 + 3 + 4 + 7 + 26 +30 + 9  = 84

Then get just the Friday + Saturday  26 + 30 = 56

Set up the fraction 56/84.  

Divide the numerator by the denominator to get the decimal

56÷84 = 0.6667  Multiply by 100 to change to percent  66 2/3 %

Answer:

78+25+61+55+64=283

360-283=77

180+77=257

The exterior angles of any polygon (a shape with 3 or more sides) is always equal to 360 degrees.

If you add up all the provided angles you get 283 degrees

The remaining angle to get to 360 is 77 since 360-283=77

If a value of 80.4° is added to the data, how does the range change?

The range decreases to 46°.
The range stays 48°.
The range stays 49°.
The range increases to 50°.

Answers

Answer:

The Range Stays 48°.

Step-by-step explanation:\

Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.

Hope this helps!

Answer:  B.  The range stays 48

Step-by-step explanation:

The largest answer is 105 and the smallest answer is 57.  The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest

Range = 105 - 57

Range = 48

The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.

So answer is B. The range stays 48

find the x-intercepts of the function g(x)=8x^{2} −10x−3

Answers

Answer: \([-\frac{1}{4}, \frac{3}{2}]\)

Step-by-step explanation:

Factor:

\(g(x) = 8x^{2} -10x-3\)\(g(x) = x^{2} -10x-24\) ---> multiply constant (3) by coefficient of first term\(g(x) = (x+\frac{2}{8})(x-\frac{12}{8} )\) ---> factor (multiplies to 24 and adds to -10. Divide factors by 8 since you multiplied by 8 in previous step)\(g(x) = (x+\frac{1}{4})(x-\frac{3}{2})\) ---> simplify\(g(x) = (4x+1)(2x-3)\) ---> move denominator of fraction to be coefficient of x

Solve:

\(0 = (4x+1)(2x-3)\) ---> set equation equal to 0.\(0 = 4x + 1\) ---> make each parentheses equal to 0.\(-1 = 4x\) \(-\frac{1}{4} = x\) ---> x intercept\(0 = 2x - 3\) \(3 = 2x\) \(\frac{3}{2} = x\) ----> x intercept

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2

Answers

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.
