An object has a mass of 328 kg and a volume of 75 m3.
Find the density of the object in kg/m3.
Give your answer rounded to 1 decimal place.

Answer:

The answer is =-24a^4+37a^2+5

Answer: Rewrite using the commutative property of multiplication.

−8⋅3(a2a2)−8a2⋅−5−1(3a2)−1⋅−5

Multiply a 2 by a 2 by adding the exponents.

Use the power rule a m a n = a m + n to combine exponents.

Answer:

-179, since it is negative then there are no real roots

Step-by-step explanation:

b²-4ac is the discriminant formula

9v² + v + 5 = 0  ∴  a = 9, b = 1, c = 5

1² - 4(9)(5) = -179

Step-by-step explanation:

1.) 700*0.42 = 294. Out of the 700 people at the concert, 294 are tennagers.

2.) 1.07*$450 = $481.50, including sales tax (final price)

3.) 120/(100%-85%) = 120/0.15 = 800. Original amount of water is 800 ml (Check by 800mL*0.15, which equals 120 mL)

Answer:

D (Isosceles Obtuse)

Step-by-step explanation:

Since 2 of the sides are the same length, that would make the triangle an isosceles.

Since 1 of the angles are over 90 degrees, that would make the triangle obtuse.

This makes the triangle an isosceles obtuse triangle.

Answer: 7.5

Step-by-step explanation: draw a right triangle to represent the slide. the slide is 15 feet long, so the hypotenuse of the right triangle would be 15 feet. The angle from the bottom is 30 degrees according to the question. You want to find the angle opposite from the 30 degree angle so use sin(30). Sin=opposite/hypotenuse so sin(30)=x/15 sin(30) is 1/2 so 1/2=x/15. You multiply by 15 on both sides to get x by itself. 1/2*15=7.5

Answer:

Corresponding angles

Step-by-step explanation:

A corresponding angles is, and I quote, "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." (See image below)

So, looking at our words and graph, 5 and 1 are corresponding angles!

Answer:

We want to solve the equation:

x*6 - 9 = 7

To solve this we need to isolate x in one side of the equation.

First, we need to add 9 in both sides of the equation to get:

(x*6 - 9) + 9 = 7 + 9

x*6 - 9 + 9 = 16

x*6 = 16

Now we can divide both sides by 6, to get:

x*6/6 = 16/6

x = 16/6 = 2.66

This is not an integer as the question wants, so i only can suppose that the question is incorrectly written.

If the equation was something like:

x/6 - 9 = 7

Using the same approach than before (the only difference is that we multiply both sides by 6 in the second step), we would get:

x/6 = 7 + 9 = 16

x/6 = 16

x = 16*6 = 96

x = 96

Which is an integer, so i suppose that the actual equation is "x/6 - 9 = 7" instead of "x*6 - 9 = 7"

The Answer is odd hope this helps :)

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(a)

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (P(16, 9) and (x₂, y₂ ) = Q(22, 24)

[tex]m_{PQ}[/tex] = [tex]\frac{24-9}{22-16}[/tex] = [tex]\frac{15}{6}[/tex] = [tex]\frac{5}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{2} }[/tex] = - [tex]\frac{2}{5}[/tex] , then

y = - [tex]\frac{2}{5}[/tex] x + c ← is the partial equation

To find c substitute (5, 1) into the partial equation

1 = - 2 + c ⇒ c = 1 + 2 = 3

y = - [tex]\frac{2}{5}[/tex] x + 3 ← equation of perpendicular line

(b)

Given PN = 2NQ , then N sections PQ in the ratio 2 : 1

Using the Section formula to find coordinates of N

N = ( [tex]\frac{16(1)+22(2)}{1+2}[/tex] , [tex]\frac{9(1)+24(2)}{1+2}[/tex] )

   = ( [tex]\frac{16+44}{3}[/tex], [tex]\frac{9+48}{3}[/tex] )

    = ( [tex]\frac{60}{3}[/tex], [tex]\frac{57}{3}[/tex] )

    = (20, 19 )

Step-by-step explanation:

Given data

Percent commission from sale= 2%

We are told that an associate earned $50 from sales

Let the amount of the sales be x

so

2/100*x= 50

0.02x=50

Divide both sides by 0.02

x=50/0.02

x=2500

Hence the sales made was $2500

Answer:

B

Step-by-step explanation:

95% of the time, population data will fall between 149.61 and 150.39.

A confidence level of 95% means 95% of the time, population data will fall between 149.61 and 150.39. The correct answer would be an option (B).

A sample is a subset of data drawn from a larger population by a researcher using a predetermined selection process. These components are referred to as sample points, sampling units, or observations.

The second statement, "95% of the time, population data will fall between 149.61 and 150.39," is more accurate in terms of what a 95% confidence level implies.

When you conduct a sample survey, you can calculate a confidence interval, which is an estimate of the range of values that the population parameter is likely to fall within.

If the confidence level is 95%, it means that if you were to repeatedly sample the population and construct a confidence interval each time, 95% of those intervals would contain the true population parameter.

Thus, the correct answer would be option (B).
