Answer:
22.44 ft
Step-by-step explanation:
The radius is equal to half of the diameter or 1.75 ft (in this case).
The volume of a sphere is defined as the equation:
V = 4/3 * pi * radius ^ 3
V = 4/3 * 3.14 * 1.75 ^ 3
V = 4/3 * 3.14 * 5.36
V = 22.44 ft

Arianna drove 180 miles in 3 hours. If she continued at the same rate, how long would it take to travel 960 miles?
Answer: 16 hours
Step-by-step explanation: If 180 miles was completed in 3 hours, it means 60 miles was completed in 1 hour (180 ÷ 3 = 60.) Now we just do 960 ÷ 60 and we get 16 hours of time at a constant speed, assuming no further alterations were made to accelerations.
If my problem was helpful, please mark it as Brainliest. It helps me earn reputation and ranks!
Arianna can travel 960 mi in 16 hours.
What is speed?Speed is defined as the rate of change of position of an object in any direction.
Given that, Arianna drove 180 miles in 3 hours.
As we know, Speed is the ratio of distance to the time in which the distance was covered.
Speed = distance/time
Ariana's speed = 180/3 = 60 mi/hr
Therefore, time taken by her to travel 960 mi = 960/60 = 16 hr.
Hence, Arianna can travel 960 mi in 16 hours.

If the perpendicular from chord is x, the length of cord is 11.3 and diameter be 15.5 then the value of x is 4.54.
Given Perpendicular from center to chord is x. The length of cord be 11.3 and the diameter be 15.5.
Perpendicular means a line on other line making an angle of 90 degrees. Cord is the length of line joining two points on a circle and is different from radius or diameter. We know that the formula of calculating the length of chord is as under:
l=[tex]2\sqrt{r^{2} -d^{2} }[/tex]
now put the value of l=11.3 and r=15.5/2=7.25
11.3=[tex]2\sqrt{7.25^{2} -x^{2} }[/tex]
11.3/2=[tex]\sqrt{52.5625-x^{2} }[/tex]
5.65=[tex]\sqrt{52.5625-x^{2} }[/tex]
squaring both sides
[tex]5.65^{2} =52.5625-x^{2}[/tex]
31.9225=52.5625-[tex]x^{2}[/tex]

A geometric series has a sum of 1365. Each item increases by a factor of 4. If there
are 6 terms in the series, find the value of the first term.
Answer:
1
Step-by-step explanation:
So the sum of a finite geometric series can be defined as: [tex]S_n = \frac{a_1-a1*r^n}{1-r}[/tex] where r is the constant ratio or how much more greater the current term is, compared to the previous term (how much it's being multiplied by), and the n is the number of terms in the series. So with the given information you have the equation:
[tex]1365=\frac{a_1-a_1*4^6}{1-4}[/tex]
Simplify:
[tex]1365=\frac{a_1-4096a_1}{-3}[/tex]
Multiply both sides by -3
[tex]-4095 = a_1-4096a_1[/tex]
Subtract coefficients
[tex]-4095=-4095a_1[/tex]
Divide both sides by -4095

Hello
Answer:
Look at the picture.
The solution to the given proportion (x-1)/5 = (x-1)/2 is equal to x = 1.
To solve the proportion (x-1)/5 = (x-1)/2, we need to find the value of x that satisfies the equation. Cross-multiplication is a common method used to solve proportions.
First, cross-multiply the equation:
2(x - 1) = 5(x - 1)
Now, distribute the values on both sides:
2x - 2 = 5x - 5
Next, isolate the variable x on one side of the equation. Let's move all terms containing x to the left side of the equation by subtracting 2x from both sides:
2x - 2 - 2x = 5x - 5 - 2x
-2 = 3x - 5
Now, let's move the constant term (-5) to the other side of the equation by adding 5 to both sides:
-2 + 5 = 3x - 5 + 5
3 = 3x
Finally, to find the value of x, divide both sides by 3:
3/3 = 3x/3
1 = x

Based on the calculations, the formula of this sinusoidal function is equal to f(x) = 6cos(2x) + 4.
How to write the formula of this function?Mathematically, the standard equation of a cosine function is given by:
y = Acos(Bx - C) + D
Where:
A is the amplitude.B = 2π/P.P is the period.C is the phase shift.D is the center line (midline).For the amplitude, we have:
A = maxline - midline
A = 10 - 4
Amplitude, A = 6.
Since the maxline to the midpoint is euqal to π/4, we have:
¼ × P = π/4
4P = 4π
P = π
For the value of B, we have:
B = 2π/P
B = 2π/π
B = 2.
Since there isn't any phase shift, the value of C is equal to zero (0) and D is equal to 4.
Next, we would substitute the parameters into the cosine function:
y = Acos(Bx - C) + D
y = 6cos(2x - 0) + 4
f(x) = y = 6cos(2x) + 4.

Abbey Co. sold merchandise to Gomez Co. on account, $29,300, terms 2/15, net 30. The cost of the goods sold is $20,510. Abbey Co. issued a credit memo for $2,500 for merchandise returned that originally cost $1,800. Gomez Co. paid the invoice within the discount period. What is the amount of gross profit earned by Abbey Co. on the above transactions?
Answer:
The amount of gross profit earned by Abbey Co. on the above transactions is $7,554.00
Step-by-step explanation:
What is the gross profit of Abbey Co?
Note that after sales of goods of $29,300 whose cost is $20,510 to Gomez Co, Gomez returned goods whose selling price is $2,500 and cost originally $1,800 to Abbey Co.
The implication of such goods returned is that $2,500 would be deducted from selling price and $1,800 would be deducted from cost of goods sold.
selling price=$29,300-$2,500
selling price=$26,800.00
cost of goods sold=$20,510-$1,800
cost of goods sold=$18,710.00
Note again that Gomez paid the invoice within the discount period, which means that net sales is the selling price of $26,800.00 minus 2% discount(2/15 means a discount of 2% is available if credit sales is settled in cash within the first 15 days of making sales0
net sales=$26,800.00*(1-2%)
net sales=$26,264.00
The gross profit is net sales minus the cost of goods sold
gross profit= $26,264.00-$18,710.00
gross profit=$7,554.00

2 2/3 * 2 2/3 = how many thirds as a fraction
Answer:
[tex]21 \frac{1}{3}[/tex] fit into the product
Step-by-step explanation:
so you want to convert [tex]2 \frac{2}{3}[/tex] into a fraction by multiplying 2 by 3 and adding it to the 2. This will give you (3 * 2) = 6 => 6+2=8 which is the numerator. So the fraction becomes [tex]\frac{8}{3}[/tex] and since the two fractions are equal they both become this. So now you have [tex]\frac{8}{3} * \frac{8}{3}[/tex] which can be calculated by multiplying the numerators and denominators. This gives you [tex]\frac{8*8}{3*3} = \frac{64}{9}[/tex]. Now this just gives you the product but the question is asking you how many one thirds is the product. This is essentially saying how many 1/3 fit into the product or in other words what is the product divided by 1/3. This gives you the equation [tex]\frac{64}{9} \div \frac{1}{3}[/tex] which can be calculated by changing the sign to multiplication and flipping the second fraction (1/3 => 3/1) This gives you the equation [tex]\frac{64}{9} * \frac{3}{1} = \frac{64 * 3}{3 * 3} = \frac{64}{3}[/tex]. I rewrote the 9 as 3 * 3 in the equation so you can see that we can just cancel out the 3. Since if have a number and multiply it by "x" and divide by "x" you just have the original number. So now you have 64/3 which simplifies to [tex]21 \frac{1}{3}[/tex]
