Answer:

0.08 g/cm³

Step-by-step explanation:

We are given;

But; 1 pound = 453.592 g

Therefore, mass = 907.184 g

But; 1 gallon = 3785.41 cm³

Thus, volume = 11356.23 cm³

We are required to determine the density of the liquid;

We need to know that;

Density = Mass ÷ Volume

Therefore;

density of the liquid = 907.184 g ÷ 11356.23 cm³

                                 = 0.0799 g/cm³

                                = 0.08 g/cm³

Thus, the volume of the liquid is 0.08 g/cm³

The measure of ∠K is 49 degrees 22 minutes 51 seconds.

Step-by-step explanation:

Given that ∠J and ∠K are complementary.

∠J = 41°38'9".

∠K = ?

When a sum of two angles result is 90°, then it is called as complementary angles.

Since ∠J and ∠K are complementary, then their sum is 90°.

∠J +∠K=90°.

∠K= 90° - ∠J.

=90°60'60" - 41°38'9".

=49°22'51".

∠K= 49 degrees 22 minutes 51 seconds.

By using the information that the scooter can travel 118 miles with 1 gallon of gasoline as a reference, we calculate that it can travel 11.8 miles with 0.1 gallons and 1180 miles with 10 gallons.

To complete the table and find the number of miles the scooter can travel for other amounts of gasoline, we can use the given information that the scooter can travel 118 miles with 1 gallon of gasoline as a reference point. We can calculate the mileage for different amounts of gasoline using this information.

Here's how we can complete the table:

Gallon 0.1:

We can calculate the distance for 0.1 gallons by taking 10% of the mileage for 1 gallon:

0.1 * 118 miles = 11.8 miles

Gallon 10:

Similarly, we can calculate the distance for 10 gallons by multiplying the mileage for 1 gallon by 10:

10 * 118 miles = 1180 miles

So, the completed table would look like this:

Gallon 0.1: 11.8 miles

Gallon 1: 118 miles

Gallon 10: 1180 miles

This table provides the number of miles the scooter can travel for different amounts of gasoline, including 0.1 gallons, 1 gallon, and 10 gallons.

Final answer:

The speed of the skater is 18 km/h.

Explanation:

To find the speed of the skater, we can set up a proportion using the information given. Let's let the speed of the skater be x km/h. Since the cyclist traveled 9 km/h faster than the skater, the speed of the cyclist would be x + 9 km/h. Now, we can set up the proportion:

(x + 9 km/h)/(45 km) = x km/h)/(30 km).

To solve this proportion, we can cross-multiply and solve for x:

(x + 9 km/h)(30 km) = (x km/h)(45 km)

30x + 270 = 45x

270 = 45x - 30x

270 = 15x

x = 18

Therefore, the speed of the skater is 18 km/h.

Answer:

m=5

Step-by-step explanation:

Since we know that triangle ABC is similar to QRS, we know that the side lengths will be proportional to one another. As such, we should take a ratio to determine the side length of m.

Choose whole numbers to make the division easier

[tex]\frac{QR}{AB} = \frac{QS}{AC} \\\frac{10}{6} = \frac{m}{3} \\\frac{10*3}{6} =m\\m=10*3/6 = 5[/tex]

The missing side length, [tex]$m$[/tex], is [tex]$\boxed{5}$[/tex].

The missing side length, [tex]$m$[/tex], can be found using the fact that triangles [tex]$ABC$[/tex] and[tex]$QRS$[/tex] are similar. This means that their corresponding side lengths are proportional. We can set up a proportion like this:

(m)/(3)=(10)/(6)

Cross-multiplying, we get:

[tex]$$6m[/tex] =[tex]30$$[/tex]

Solving for [tex]$m$[/tex], we get:

[tex]$$m[/tex] =[tex]5$$[/tex]

Therefore, the missing side length, [tex]$m$[/tex], is [tex]$\boxed{5}$[/tex].

a) Wayne's savings before he spent $28 is $30

b) Stef's savings after she spent $28 is $8

Step-by-step explanation:

step 1 :

let,

Wayne's savings = 5x

Stef's savings = 6x

step 2 :

After spending $28 each of them, The ratio becomes 1/4.

⇒ (28 - 5x) / (28 - 6x) = 1/4

⇒ 4(28 - 5x) = 1 (28 - 6x)

⇒ 112 - 20x = 28 - 6x

⇒ 112 - 28 = 20x - 6x

⇒ 84 = 14 x

x = 84/4 = 6

step 3 :

a) Wayne's savings before he spent $28 = 5x

substitute x=6,

Wayne's savings = 5(6) = $30

step 4 :

b) Stef's savings after she spent $28 = Total savings - $28

                                                             = 6x - 28

                                                             = 6(6) - 28

∴ Stef's savings after she spent $28  = 36 - 28 =$8

(a) Wayne's savings before he spent $28 is $30.

(b) Stef's savings after she spent $28 is $8.

Solution:

Ratio of Wayne's savings to Stef's savings = 5 : 6

Let x be the common amount they have.

After spending $28 each, the ratio becomes 1 : 4.

5x – 28 : 6x – 28 = 1 : 4

This can be written in a fraction form.

[tex]$\Rightarrow\frac{5x-28}{6x-28}=\frac{1}{4}[/tex]

Do cross multiplication.

[tex]$\Rightarrow 4(5x-28)}=1({6x-28})[/tex]

[tex]$\Rightarrow 20x-112=6x-28[/tex]

Arrange like term one side.

[tex]$\Rightarrow 20x-6x=112-28[/tex]

[tex]$\Rightarrow 14x=84[/tex]

⇒ x = 6

(a) Wayne's savings before he spent $28 = 5x = 5(6) = $30

(b) To find stef's savings after spent $28:

Stef's savings before she spent $28 = 6x = 6(6) = $36

Stef's savings after she spent $28 = $36 – $28 = $8

Hence Wayne's savings before he spent $28 is $30

Stef's savings after she spent $28 is $8.

Final answer:

To calculate the cost per second for a $4 million Super Bowl ad that runs for 30 seconds, divide the total cost by the number of seconds, yielding a cost of approximately $133,333.33 per second.

Explanation:

The question asks us to calculate the cost per second for Super Bowl commercial air time when 30 seconds of air time sold for $4 million. To find the price per second, we divide the total cost by the total number of seconds.

Price per second = Total cost ÷ Number of seconds

Price per second = $4,000,000 ÷ 30 seconds

Price per second = $133,333.33 (rounded to the nearest cent)

Therefore, the price per second for Super Bowl commercial air time was approximately $133,333.33.

Answer:

ED=12 units

Step-by-step explanation:

From the diagram triangle EAB is similar to triangle EDC.

The corresponding sides will be proportional.

EA/ED=AB/DC

This implies that:

[tex] \frac{2x + 4}{x + 4} = \frac{9}{6} [/tex]

We cross multiply to get:

[tex]6(2x + 4) = 9(x + 4)[/tex]

We expand to get:

[tex]12x + 24 = 9x + 36[/tex]

Group similar terms to get:

[tex]12x - 9x = 36 - 24[/tex]

Combine the similar terms to get:

[tex]3x = 12[/tex]

Divide through by 3 to get:

[tex]x = \frac{12}{3} [/tex]

This will simplify to:

[tex]x = 4[/tex]

Therefore ED=2*4+4=8+4=12

Answer:

The density of oak is 0.695 grams per cubic centimeter.

Step-by-step explanation:

Given:

Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.

Now, to find the density of oak in grams per cubic centimeter.

Mass (m) = 2.85 kilograms.

So, using conversion factor we convert into grams:

[tex]2.85\times 1000=2850\ grams.[/tex]

Volume (v) = 4100 cubic centimeters.

Now, to get the density by using formula:

[tex]Density=\frac{mass}{volume} \\Density=\frac{m}{v}[/tex]

[tex]Density=\frac{2850}{4100}[/tex]

[tex]Density=0.695\ grams\ per\ cubic\ centimeter.[/tex]

Therefore, the density of oak is 0.695 in grams per cubic centimeter.

To find the x-coordinates of the points where the graph crosses the x-axis, set y = 0 and solve for x. The x-coordinates are 3 and -8.

The question asks for the x-coordinates of the points where the graph of the equation y = (x - 3)(x + 8) crosses the x-axis. To find these points, we need to determine the values of x that make y equal to zero. Setting y = 0, we get (x - 3)(x + 8) = 0. This equation will be true if either (x - 3) = 0 or (x + 8) = 0. Solving each equation gives us x = 3 and x = -8, respectively. These are the x-coordinates of the points where the graph crosses the x-axis.

To find the x-coordinates where the graph of y = (x - 3)(x + 8) crosses the x-axis, set y to zero and solve for x, yielding the points (3, 0) and (-8, 0).

To find the x-coordinates where the graph crosses the x-axis, we need to set the y-value to zero and solve the equation. This is because when a graph crosses the x-axis, its y-coordinate is always zero. The equation given is y = (x - 3)(x + 8).

To find the x-coordinates, we set y to zero:

x = -8

Thus, the graph crosses the x-axis at the points (3, 0) and (-8, 0).

Answer:

$10,500 in the 8% interest account,

$31,000 in the 15% interest account

Step-by-step explanation:

Let

x ---> the amount invested in the 8% interest account

41,500-x ----> the amount invested in the 15% interest account

we know that

The amount  invested in the 8% interest account multiplied by the interest in decimal form plus the amount invested in the 15% interest account multiplied by the interest in decimal form, must be equal to $5,490

so

The linear equation that represent this problem is

[tex]0.08x+0.15(41,500-x)=5,490[/tex]

solve for x

[tex]0.08x+6,225-0.15x=5,490\\0.15x-0.08x=6,225-5,490\\0.07x=735\\x=\$10,500[/tex]

so

[tex]41,500-x=41,500-10,500=\$31,000[/tex]

therefore

$10,500 in the 8% interest account,

$31,000 in the 15% interest account

Solution:

An A grade will be given to students having at least 450 total test points

Let p represent her present test point total, and t represent the necessary average on the next two tests

There are two more tests to take before the semester is over

Therefore,

[tex]p+2t\geq 450[/tex]

A grade is given to students having at least 450 total test points

"at least" means greater than or equal to

So we have used greater than or equal to symbol

Solve the inequality for "t"

[tex]p+2t\geq 450\\\\Subtract\ p\ from\ both\ sides\\\\2t\geq 450-p\\\\Divide\ both\ sides\ by\ 2\\\\t\geq \frac{450-p}{2}[/tex]

Thus the required average on next two tests are:
