Multiplying each side by 3/4, we get (3/4)V=pir^3. Dividing both sides by pi, we then get r^3=(3/4)V/pi

For the second part, we get that 381.51=(4/3)πr^3, so plugging 381.51 into the equation above we get (3/4)(381.51)/pi=around 91, and r= the cube root of r^3, which would equal around 4.5 here

Your car is a real gas guzzler getting 15 miles to the gallon on the highway using regular gas which at this time costs $ 4.35/gallon. You have a 25 gallon tank in the car and want to drive to visit a trade show in Memphis, Tennessee which is 1780 miles from Los Angeles. You drive on average 70 miles per hour and spend 2 days and nights at the convention during which time you do not drive your car, You do however check into a hotel room which costs $95.00 per night plus a 12% room tax. Your meals cost a total of $35.00 per day for the 2 days that you are in town. You also decide to leave a tip for the waiter of 20% of your meal bill. On the last day of the trip, you decide to purchase an Apple iPod as a gift for your child and an iPad Tablet for yourself which costs $ 589.00. The iPad costs $589.95 and the iPod costs $ 265.95 plus sales tax of 9.25%. What is the total amount yo will spend for the trip? What are the key elements of the problem and what is the answer?

A washer and a dryer cost $917 combined. The washer costs $67 more than the dryer. What is the cost of the dryer?

Answers

Final answer:

To find the cost of the dryer, set up equations based on the given information and solve for the dryer's cost, which results in the dryer being priced at $425.

Explanation:

To solve for the cost of the dryer in the given problem, we can create two equations based on the information provided. Let's denote the cost of the dryer as D and the cost of the washer as W. According to the problem, W = D + $67, and the combined cost of the washer and dryer is $917, so W + D = $917.

Substituting the first equation into the second, we have (D + $67) + D = $917. Simplifying this, we get 2D + $67 = $917. Subtracting $67 from both sides of the equation gives us 2D = $850. Finally, dividing both sides by 2, we find that D = $425.

Therefore, the cost of the dryer is $425.

Emelina wrote the equation of a line in point-slope form as shown below. (y+4)=3(x+2) What is Emelina’s equation in slope-intercept form?

Answers

y + 4 = 3(x + 2)
y + 4 = 3x + 6
y = 3x + 6 - 4
y = 3x + 2 <=== slope intercept form

Answer:

[tex]y=3x+2[/tex]

Step-by-step explanation:

We are given equation as

[tex](y+4)=3(x+2)[/tex]

Since, we have to write equation in slope-intercept form

so, we can use slope-intercept formula

[tex]y=mx+b[/tex]

where m is a slope

b is y-intercept

so, we can write our equation in this form

[tex](y+4)=3(x+2)[/tex]

Distribute 3

[tex]y+4=3\times x+3\times 2[/tex]

[tex]y+4=3x+6[/tex]

Subtract both sides by 4

[tex]y+4-4=3x+6-4[/tex]

[tex]y+4-4=3x+6-4[/tex]

[tex]y=3x+2[/tex]

So, slope-intercept form of equation is

After working for 25 hours lammer made $375 after working 40 hours lammer made $600 predict how much will he make after 10 hours of work

Answers

25hr. 40h. 10hr

375$ 600$ x

25 . 40 . x = 1000
375 . 600 = 225000
225000÷1000
x = 225

Lammer will make $150 after working for 10 hours .

Calculating Earnings Based on Hours Worked

To predict how much Lammer will make after working 10 hours, we first need to determine his hourly wage. From the information given, we know:

After working 25 hours, Lammer made $375.After working 40 hours, Lammer made $600.

We can calculate his hourly wage as follows:

Hourly Wage = Total Earnings / Total Hours Worked

For both inputs, we observe:

$375 / 25 hours = $15 per hour$600 / 40 hours = $15 per hour

This indicates that Lammer's hourly wage is consistent at $15 per hour.

Now, to predict how much he will make after working 10 hours:

Earnings for 10 Hours of Work = Hourly Wage x Number of Hours

Earnings for 10 Hours = $15 x 10 = $150

Therefore, Lammer will make $150 after working 10 hours.

[tex]\angle 4 +\angle5 = 180^\circ[/tex]

[tex]\angle 5 +\angle6 = 180^\circ[/tex]

[tex]\angle 7 +\angle8 = 180^\circ[/tex]

A projectile is shot from a cannon. The fixed parameters are the acceleration of gravity,    g=9.8 m/sec2, and the muzzle velocity, v0=500 m/sec, at which the projectile leaves the cannon. The angle θ, in degrees, between the muzzle of the cannon and the ground can vary. The range of the projectile is
f(θ)=vo^2/g sin πθ/90=25510 sin πθ/90 meters.

Answers

The range at θ = 10⁰ is 155.4 meters.

What is a projectile?

A projectile is an object thrown or projected into the air, subject to gravity, following a curved trajectory.

Given that

v₀ = 500m/s

g = 9.8 m/s²

θ = 10⁰

Substitute into the function

f(θ)=v₀²/g sin πθ/90=25510 sin πθ/90 meters.

f(θ)= 25510sin πθ/90

= 25510sin10π/90

= 25510sinπ/9

= 25510sin(3.142/9)

= 25510sin(0.349)

= 25510 * 0.00609

= 155.4 m

The range at θ = 10⁰ is 155.4 meters.

Complete question

Final answer:

The greater the initial velocity of a projectile, the greater the range, with the maximum range achieved at a 45° angle in the absence of air resistance.

Explanation:

The initial velocity of a projectile has a significant impact on its range. Specifically, the greater the initial speed, ℓ0, the greater the range. The formula for range R on level ground, neglecting air resistance, is given by R = (v0²/g) sin(2θ), where θ is the launch angle, v0 is the initial velocity, and g is the acceleration due to gravity. The maximum range is reached when the launch angle is 45°. With air resistance, the optimal angle decreases to roughly 38°. Additionally, for every angle other than the optimal, there are two different angles that yield the same range, and their sum totals 90°.

Josh and Eva are packing first-aid supplies. It takes Josh 12 minutes to fill a box with Bandages. It takes Eva 8 minutes to fill a box with antibiotics. If they start packing boxes at the same time, how long will it be before they start filling a new box at the same time.

Answers

The lowest common multiple of 8 and 12 is 24. So ur answer is 24 minutes
Here, you just want to find the LCM, or the Least Common Multiple, or the closest time when both of their numbers meet.

(If that makes any sense)

So their LCM is 24, because:

8: 8, 16, 24

And 24 is the closest number they meet at.

So it will be 24 minutes before they start filling a new box at the same time.

weight A weighs 50 pounds. weight B weighs 100 pounds. if A is placed 6 feet from the pivot, how far must B be placed from the pivot in order for the bar to achieve balance?

Answers

To achieve balance, the momentum on both sides must be equal so that it cancels out. Momentum is simply the product of mass and distance, therefore:

 

50 pounds * 6 ft = 100 pounds * X

X = 3 ft

 

Hence B must be placed 3 ft from the pivot.
