Answer: 48 ft

Step-by-step explanation:

The height gap between the balloons is 60 -40 = 20 feet. That gap is being closed at the rate of 2 + 3 = 5 ft/s, so will be gone in ...

 (20 ft)/(5 ft/s) = 4 s

At that time, the red balloon will have risen (2 ft/s)(4 s) = 8 ft to a height of ...

 40 ft +8 ft = 48 ft

The blue balloon will have descended (3 ft/s)(4 s) = 12 ft to a height of ...

 60 ft -12 ft = 48 ft

The balloons at at 48 ft when they are both the same height.

_____

Time and speed and distance are related by the formula you see on every speed limit sign:

 speed = distance/time . . . . . . . (on the sign, it's "miles per hour")

or

 time = distance/speed

or

 distance = speed × time

_____

If you want equations, you can write them as ...

 h = 40 +2t

 h = 60 -3t

where h is the altitude the balloons have when they are at the same height, and t is the number of seconds it takes to get there.

We're only interested in h, so we can cancel t by multiplying the first equation by 3 and adding that to the second equation multiplied by 2:

 3(h) + 2(h) = 3(40 +2t) +2(60 -3t)

 5h = 120 +6t +120 -6t

 h = 240/5 = 48 . . . . the height in feet at which the balloons are the same height

If m || n and line t cuts them, the value of x is 17 degree

Given that, the line m || line n. and we need to find the value of x

If two lines are parallel and a transversal cuts them then the corresponding alternate interior angles are equal.

Here, line m and line are parallel anf the transversal t cuts them, so the alternate interior angles will be same

2x - 5 = 3x - 22

2x - 3x = - 22 + 5

- x = - 17

x = 17

Therefore, if m || n and line t cuts them,  the value of x is 17 degree

Given the following data set:

[13,13,13,15,15,16,16,17,17]​

Let's determine the median.

Step 1: Arrange the data points from smallest to largest.

The set is already arranged in ascending order.

[13,13,13,15,15,16,16,17,17]​

Step 2:

a.) If the number of data points is odd, the median is the middle data point in the list.

b.) If the number of data points is even, the median is the average of the two middle data points in the list.

There are 9 data in the set, it is odd. The middle data is the 5th data.

[13,13,13,15,15,16,16,17,17]​

The 5th data is 15.

Therefore, the median of the given set of data is 15.

The smallest and greatest number that rounds to 380 when rounding to the nearest ten are 375 and 384 respectively.

Adjusting a number's digits so that it produces an approximation of a result is known as rounding.

The given number is 380.

When rounding a number to the nearest ten, pay attention to the last digit; if it is less than five, round down; if it is five or more, round up.

Therefore, the smallest number that rounds to 380 when rounding to the nearest ten is 375.

Similarly, the greatest number that rounds to 380 when rounding to the nearest ten is 384.

Hence, the smallest and greatest number that rounds to 380 when rounding to the nearest ten are 375 and 384 respectively.

The point R represents the number -2.5 on the number line

From the question, we understand that the point R is halfway between the integers on the number line

This means that

Point R = 1/2 * (a + b)

Where variables a and b represent the boundaries of the integers

In this case, we have

a =-2

b = -3

Substitute a =-2 and b = -3 in the equation Point R = 1/2 * (a + b)

So, we have

Point R = 1/2 * (-2 - 3)

Evaluate the difference

Point R = 1/2 * -5

Evaluate the product

Point R = -2.5

Hence, the location of R on the number line is  -2.5

The current is defined as rate of flow of charge I = dq/dt

Let the equation be [tex]$q=\int i d t$[/tex]

Given: I(t) = 10 cos(120πt - 12π) + 5

We will substitute it in the above equation

q = [tex]$$\int[/tex] 10 cos(120πt - 12π) + 5 dt

now here limits of time is from t = 0.1 to t = 60 s

so here it will be given as

[tex]$\int 10 cos(120\pi t - 12\pi ) + 5 dt[/tex]

Rewrite using trig identities

[tex]$=\int_{0.1}^{60} 10 \cos (120 \pi t)+5 d t$$[/tex]

Apply the Sum Rule:

[tex]$\int f(x) \pm g(x) d x=\int f(x) d x \pm \int g(x) d x$[/tex]

substitute the values in the above equation, we get

[tex]$=\int_{0.1}^{60} 10 \cos (120 \pi t) d t+\int_{0.1}^{60} 5 d t$[/tex]

simplifying the equation,

[tex]$\int_{0.1}^{60} 10 \cos (120 \pi t) d t=0[/tex]

[tex]$\int_{0.1}^{60} 5 d t=299.5$[/tex]

What is basic arithmetic?

Specific numbers and their computations employing a variety of fundamental arithmetic operations are at the center of arithmetic mathematics. Algebra, on the other hand, deals with the limitations and guidelines that apply to all other types of numbers, including whole numbers, integers, fractions, functions, and so on. Arithmetic math serves as the foundation for algebra, which always adheres to its definition. A large range of subjects fall within the broad definition of mathematics, which encompasses a very broad range of topics. Beginning with the fundamentals like addition, subtraction, and division of numbers, they then move on to more complicated topics like exponents, variations, sequence, progression, and more. This part does touch on some of the mathematical formulas and mathematical sequence. Four essential mathematical operations—addition, subtraction, multiplication, and division—are covered in basic arithmetic.

B.

If the first computer chosen is the one defective, the probability of the first PC being defective is 4/10, the probability of the second one not being defective will be 6/9, for the third not being defective is 5/8 and for the fourth not being defective is 4/7.

Since the defective PC can be any of the 4 bought, we need to multiply the probability above by 4. So the final probability is:

Answer:

x = 2.64

Step-by-step explanation:

Do the distributive property first.

0.9(x + 1.4)

0.9(x) + 0.9(1.4)

0.9x + 1.26 - 2.3 + 0.1x = 1.6

Simplify the left side by adding like terms. I'm going rewrite the equation and group the like terms together.

0.9x + 0.1x + 1.26 - 2.3 = 1.6

1x - 1.04 = 1.6

1x is the same as x, so I am going to remove the 1. Solve for x.

x - 1.04 + 1.04 = 1.6 +1.04

The area of the given flag is 1187.5 square inches.

Given that, the United States flag has a height : width ratio of 10 : 19.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Let the sum of Height and width of flag be x.

Now, 10+19=29

⇒ 10/29 ×x = 25

⇒ 10x=29 × 25

⇒ x=72.5

So, width = 72.5-25 =47.5

Area of flag = Length × Width

= 25 × 47.5

= 1187.5 square inches

Therefore, the area of the given flag is 1187.5 square inches.
