Answer:

Let's suppose that the ideal blood pressure is 100 (the ideal values are between 90 and 110, i am taking the middle value)

If 125 is the 100%, and we want to go to 100, then we need to decrease by:

125 - 100 = 25

now, to calculate the percentage that represents the 25, we need to calculate:

(25/125)*100% = 20%

So to reduce his blood pressure to normal, he must reduce it by 20%

To find out by what percentage Cory must reduce his blood pressure to normal, subtract the normal from Cory's blood pressure, divide the result by Cory's initial blood pressure, and then multiply by 100. For instance, if normal blood pressure is 120, Cory must reduce his blood pressure by approximately 4%.

To calculate the percentage that Cory needs to reduce his blood pressure, we first need to know the normal blood pressure level. For example, if the normal blood pressure is considered to be 120, then we can proceed as follows:

So, Cory would need to reduce his blood pressure by approximately 4% to return to a normal level, assuming normal blood pressure is 120.

The length of BC is needed because it is the side opposite ∠A.

Step-by-step explanation:

Given the right angles triangle as shown in the attachment, we can get sin(A) without using Pythagoras theorem. Instead we will use SOH CAH TOA trigonometry identity.

According to SOH:

Sin(A) = Opposite/Hypotenuse

Sin(A) = |BC|/|AB|

Opposite side of the triangle is the  side facing ∠A.

Based on the formula, we will need to get the opposite side of the triangle which is length BC for us to be able to determine sinA since the hypotenuse is given.

If a fraction can be expressed as the product of two equal fractions, it may also be expressed in its simplest form as a perfect square.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

A fraction is a perfect square if both the numerator and the denominator of its reduced version, which is an improper fraction if the integer is greater than 1, are perfect squares. To put it another way, 25/36 is a perfect square as 25 and 36 are both perfect squares.

Thus, if a fraction can be expressed as the product of two equal fractions, it may also be expressed in its simplest form as a perfect square.

Answer: the total price of the trip is

$1087.5

Step-by-step explanation:

The trip costs $1450 and they have a special discount of 35% off. It means that the amount that would be taken off is

35/100 × 1450 = $507.5

The cost of the trip would be

1450 - 507.5 = $942.5

The tax rate for the package is 10%. It means that the amount of tax to be paid is

10/100 × 1450 = $145

Therefore, the total price of the trip would be

942.5 + 145 = $1087.5

Accoridng to your question we have to find the square root of 0.0025

However students face some problem in finding square roots of number in decimal but it is too easy to find .

√0.0025

0.05 is the square root of 0.0025

after decimal there are two zero and by square root there will be one zero and 25 is the square root of 5 .

so thus we find the square root amd the correct answer is 0.05

The square root of 0.0025 is 0.05, which follows the rule that the square root of a decimal results in half the number of decimal places in the square root, compared to the original number.

The student has asked to find the square root of 0.0025. When expressed as a square root, the number 0.0025 is equal to 0.05 because (0.05 * 0.05 = 0.0025). This can be understood by recognizing that the decimal places need to be managed correctly when finding the square root of a decimal. For instance, the square root of 25 is 5, and since 0.0025 has four decimal places, the square root will have half as many decimal places, resulting in 0.05. This concept is further emphasized by using fractional powers, such as re-expressing a number squared (x²) as the square root ( √x ), where x to the power of 2 is the same as x to the power of 1/2.

Answer:

4 m/s downwards

Step-by-step explanation:

Velocity is given by dividing the distance by time taken to cover the diatance. Therefore, expressed as v=d/t

The distance is given as 24 m but the time given covers only half the distance. Therefore, the distance is 0.5*21=12 m

Time taken is given as 3 s

Substituting 12 m for d and 3 s for t then

V=12/3= 4 m/s

Velocity must have direction component hence velocity is 4 m/s downwards

Answer:

Step-by-step explanation:

The way I thought about this was, you need to figure out how many apples per percent. Thus, I divided 420 by 35, which gave me 12.

We have deduced that every percent = 12 apples.

Multiply 12 by 100 (apples per percent x total percentage)

12 x 100 = 1200

Answer:

848 ft³

Step-by-step explanation:

The volume of a cylinder is given as:

V = pi * r² * h

Where r = radius of the cylinder

h = length of the cylinder.

The diameter of the cylindrical pipe, d = 6 ft

The radius of the cylindrical pipe, r = d/2 = 6 / 2 = 3 ft

The length of the cylindrical pipe, h = 30 ft

The volume of the cylindrical pipe is:

V = 3.14 * 3² * 30

V = 847.8 ft³ = 848 ft³ (to the nearest whole number)

The volume of the cylindrical pipe is 848 ft³.

The volume of a cylindrical construction pipe with a diameter of 6 ft and length of 30 ft can be calculated using the formula for the volume of a cylinder (V = πr²h). Given the specifics, the volume of the pipe is approximately 848 cubic feet.

The subject of this question is determining the volume of a cylinder, in this case, a construction pipe. The formula used to calculate the volume of a cylinder is V = πr²h. Here, the diameter of the cylindrical pipe is 6 ft, therefore radius (r) is half of diameter which is 6/2 = 3 ft and the length of the pipe, h, is 30 ft. Substituting r and h into the equation, we have V = 3.14 * (3ft)² * 30ft = 3.14 * 9ft² * 30ft = 847.8 cubic feet. Rounding to the nearest whole number, the volume of the pipe is approximately 848 cubic feet. The unit of volume in this instance is cubic feet, which is a measure of space occupied by a three-dimensional object.

Answer: 4 hours

Step-by-step explanation: If you take 50 times 4 it will get you 200. Another way to look at it is the car is going 50 miles per hour, so in one hour the car has gone 50 miles, in two hours it’s gone 100, three hours it’s gone 150, so in four hours it’s gone 200 miles

Final answer:

To calculate how long it takes to travel 200 miles at a constant speed of 50 miles per hour, divide the distance by the speed. The car will take 4 hours to cover the distance.

Explanation:

To determine how long it takes a car moving at a constant speed to cover a certain distance, we use the formula time = distance \/ speed. In this case, the car is moving at a constant speed of 50 miles per hour and needs to cover a distance of 200 miles.

We can calculate the time it will take as follows:

Time = Distance \/ Speed
Time = 200 miles \/ 50 miles per hour
Time = 4 hours

Therefore, it will take the car 4 hours to travel 200 miles at a constant speed of 50 miles per hour.

Answer:

[tex]\dfrac{24}{31}[/tex]

Step-by-step explanation:

Given information:

Total number of girls = 14

Total number of boys = 17

Total number of peoples = 14 + 17 = 31

6 girls and 7 boys brought balloons.

Let A and B are two events, such that

A = Choosing a girl

B = Choosing someone who did not bring a balloon.

[tex]A\cup B[/tex] = Choosing girl or someone who did not bring a balloon.

[tex]n(S)=31,n(A)=14,n(B)=18,n(A\cup B)=14+10=24[/tex]

The probability of randomly choosing a girl or someone who did not bring a balloon is

[tex]P=\dfrac{n(A\cup B)}{n(S)}[/tex]

[tex]P=\dfrac{24}{31}[/tex]

Therefore, the required probability is [tex]\dfrac{24}{31}[/tex].

The probability of randomly choosing a girl or someone who did not bring a balloon at a party is 24 out of 31, which simplifies to the fraction 24/31.

To solve this problem, we can use the concept of probability and the addition rule since the events are not mutually exclusive.

First, let's define the total number of people at the party: 14 girls + 17 boys = 31 people.

Next, we look at the number of girls who brought balloons, which is 6, meaning there are 14 - 6 = 8 girls who did not bring balloons.

Similarly, 17 boys - 7 boys who brought balloons = 10 boys who did not bring balloons.

Now, let's calculate the number of ways to choose a girl or someone who did not bring a balloon. For the girls, it's simply the total number of girls, 14. For those who did not bring balloons, we need to add the number of girls who did not bring balloons to the number of boys who did not bring balloons: 8 girls + 10 boys = 18 people who did not bring a balloon.

Combining these, the event of choosing a girl overlaps with the event of choosing someone who did not bring a balloon, so we have to subtract the number of girls who did not bring a balloon once to avoid double-counting: 14 + 18 - 8 = 24.

Thus, the probability is: 24 out of 31, which we can write as 24/31.
