Answer:

Both trains will meet at 2.2 hours (2 hours and 12 minutes).

Step-by-step explanation:

Relative Speed

If two moving objects are traveling through the same line and have speeds v1 and v2 respectively, their relative speed is vr = v1-v2.

Both trains travel toward each other, which means their speeds are of opposite signs.

Let's assume the first train has a positive speed of 65 mph, and the second train has a negative speed of -85 mph. Then, the relative speed is vr = 65 + 85 = 150 mph.

To calculate the time they take to meet, we apply the formula:

[tex]\displaystyle t=\frac{x}{vr}[/tex]

[tex]\displaystyle t=\frac{330}{150}=2.2\ hours[/tex]

Both trains will meet at 2.2 hours (2 hours and 12 minutes).

Answer:

[tex]r^{2}=\frac{V}{\pi h}[/tex]

Step-by-step explanation:

To solve an equation for one of its variables do that:

Let us use these steps to solve our question

∵ V = πr²h

→ Underline r²

∴ V = πr²h

→ Take π and h to the other side by dividing both sides by πh

∵ [tex]\frac{V}{\pi h}=\frac{\pi r^{2}h}{\pi h}[/tex]

∴ [tex]\frac{V}{\pi h}=r^{2}[/tex]

→ The coefficient of r² is 1, so switch the two sides

∴ [tex]r^{2}=\frac{V}{\pi h}[/tex]

Answer:

45

Step-by-step explanation:

If 30% of the marbles are blue and 40% are green, then the remaining 30% of the marbles are red. Now we have to find 30% of 150

We do (30/100)*150 which equals 45.

Answer:

1742 inches squared

Step-by-step explanation:

Surface Area = 2×(20×21 + 20×11 + 21×11) = 1742 inches2

We have

[tex]\sqrt[k]{\Gamma\left(\dfrac1k\right) \Gamma\left(\dfrac2k\right) \cdots \Gamma\left(\dfrac kk\right)} \\\\ = \exp\left(\dfrac{\ln\left(\Gamma\left(\dfrac1k\right) \Gamma\left(\dfrac2k\right) \cdots \Gamma\left(\dfrac kk\right)\right)}k\right) \\\\ = \exp\left(\dfrac{\ln\left(\Gamma\left(\dfrac1k\right)\right)+\ln\left( \Gamma\left(\dfrac2k\right)\right)+ \cdots +\ln\left(\Gamma\left(\dfrac kk\right)\right)}k\right)[/tex]

and as k goes to ∞, the exponent converges to a definite integral. So the limit is

[tex]\displaystyle \lim_{k\to\infty} \sqrt[k]{\Gamma\left(\dfrac1k\right) \Gamma\left(\dfrac2k\right) \cdots \Gamma\left(\dfrac kk\right)} \\\\ = \exp\left(\lim_{k\to\infty} \frac1k \sum_{i=1}^k \ln\left(\Gamma\left(\frac ik\right)\right)\right) \\\\ = \exp\left(\int_0^1 \ln\left(\Gamma(x)\right)\, dx\right) \\\\ = \exp\left(\dfrac{\ln(2\pi)}2}\right) = \boxed{\sqrt{2\pi}}[/tex]

Step-by-step explanation:

The number [tex]316_7[/tex] is 316 in base seven

The number 316 in base seven is 160 in base ten

To convert to base 10, we make use of the product rule.

So, we have:

[tex]316_7 = 3 * 7^2 + 1 * 7^1 + 6 * 7^o[/tex]

Evaluate the exponents

[tex]316_7 = 3 * 49 + 1 * 7 + 6 * 1[/tex]

Evaluate the products

[tex]316_7 = 147 + 7 + 6[/tex]

Evaluate the sum

[tex]316_7 = 160[/tex]

Hence, the number 316 in base seven is 160 in base ten

Answer:

ok so.... how much does money Becca have? however much that is add 16 to it and that should be the amount of money mark has.

Step-by-step explanation:

The height of the object after 1 sec is 284 feet

Given the equation of height of an object expressed as:

h(t) = -16t^2 + 300t

We are to find the height of the object after 1 sec. To do that, we will substitute t = 1 into the following expression

h(t) = -16t^2 + 300t

h(1) = -16(1)^2 + 300(1)

h(1) = -16 + 300

h(1) = 284ft

Hence the height of the object after 1 sec is 284 feet

Answer:

Step-by-step explanation:

The answer to your question is  7n ≤  28

Data

Cost of 1 bag = $7

The maximum amount of money spent = $28

n = number of 3-pound bags

Process

- We know that the amount spent must be at most = $28, so we use the symbol ≤.

- The money spend is the price of one bag times the number of bags bought.

- Then the inequality is

                                     7n ≤ 28

Answer: It doubles

Step-by-step explanation:

Inflation erodes the value of a currency thereby reducing the purchasing power that customers have as they will only be able to buy less gods and services for the same amount as before.

An increase in inflation is directly proportional to a decrease in purchasing power which means that if the inflation rate doubles, the decrease in purchasing power doubles as well.

For instance, if inflation is 10%, the value of a dollar becomes 0.9c. If Inflation doubles to 20%, the dollar goes to 0.8c. Meanwhile the purchasing power would have gone from $1 to 0.8c which would translate to a 20% decrease.
