A new health drink has 130% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 45 mg. How many milligrams of the vitamin are in the drink?
In the drink , there are 58.5 milligrams of vitamin .
In the question ,
it is given that
the recommended daily allowance for a certain vitamin is = 45 mg
we have to find the quantity of the vitamin in the drink ,
also given that the amount of vitamin that the new drink has is = 130% of RDA ,
on substituting the value of recommended daily allowance ,
we get
amount of vitamin in the drink is = 130% × 45
= 1.3 × 45 ... because 130% = 1.3
= 58.5 mg
Therefore , the drink has 58.5 milligrams of the vitamin .

How would you write (a-b)^5 without simplifying it?
The way we can write the expression (a - b)⁵ without simplifying is by using Pascals' Triangle to get; a⁵ + 5a⁴b + 10a³b² + 10a²b³ + 5ab⁴ + b⁵
How to use Pascals' Triangle of binomial coefficients?Pascal’s Triangle is a method that is used to know the binomial coefficients of terms of binomial expression (x + y)ⁿ, where n can be any positive integer and x,y are real numbers.
For the expression (x + y)⁵, the coefficients are;
1, 5, 10, 10, 5, 1
According to the binomial expansion, the power of m will be decreasing while the power of 5 will be increasing as shown below. Thus;
(a - b)⁵ = (a + (-b))⁵ = a⁵ + 5a⁴b + 10a³b² + 10a²b³ + 5ab⁴ + b⁵

Step-by-step explanation:
Brown bears attempt to catch salmon. during the day, 20% of the attempts are successful. during the night, 36% of attempts are successful. a bear tries to catch 40 fish during the day and makes 50 attempts at night. use probability to estimate the number of fish the bear caught.
The probability for the number of fish the bear caught is 0.289
Given,
Number of fish the bear tries to catch during day = 40
Number of attempts made by the bear at night = 50
Percentage of successful attempts during day = 20%
Percentage of successful attempts at night = 36%
Number of fish the bear caught during day = 40 × (20/100) = 4 × 2 = 8 fish
Number of fish the bear caught at night = 50 × (36/100) = 36/2 = 18 fish
Total number of fish the bear caught = 8 + 18 = 26 fish
Now,
Probability for the number of fish the bear caught:
Probability = Number of fish caught / Total attempts
Probability = 26 / (40 + 50)
Probability = 26 / 90
Probability = 0.289
Therefore,
The probability for the number of fish the bear caught is 0.289

The area of a square field is 3.24hectares . Find its perimeter in decimeters
The filed has a perimeter value of 720000 decimeters
How to determine the perimeter of the field?From the question, the area of the field is given as
Area = 3.24 hectares
Also, we have the shape of the field to be square
So, we start by calculating the side length of the field using
Length = √Area
Substitute the known values in the above equation
Length= √3.24 hectares
Length= √3.24 * 10000 square meters
Evaluate the square root
Length= 18000 meters
The perimeter is calculated as
P = 4 * Length
So, we have
P = 4 * 18000 meters
Evaluate
P = 72000 meters
Convert
P = 720000 decimeters

BD//EF, BF//DE
AB=8cm BC=12cm
x=?
The value of x is 4.8cm.
Here BD // EF and BF // DE
So from this, we have ∠ABF = ∠EFC
Let's take two triangles ΔABC and ΔFCE
∠C =∠C (common angle)
∠ABC = ∠EFC
So ΔABC ≅ ΔEFC
So ∠BAC = ∠FEC
AB/ EF = BC/ FC
AB = 8cm, EF =x, BC = 12cm, FC= 12-x
8/x = 12/ 12-x
2/x = 3/ 12-x
24 - 2x = 3x
5x = 24
x = 4.8cm
Therefore the value of x is 4.8cm.

Answer: y = (5x/4) + 2
Step-by-step explanation:
Answer:
y = 5/4x + 2
Step-by-step explanation:
First, we convert 4x + 5y = 15 to slope intercept form (y=mx+b):
5y = -4x + 15
Divide both sides by five
y = -4/5 (x) + 3
The slope is -4/5
A perpendicular slope is the negative reciprocal of the other line. To find the negative reciprocal, you switch the numerator and denominator and switch the sign.
Slope = 5/4
Plug the slope and (-4, -3) into the slope-intercept form:
-3 = ( 5/4 · -4 ) + b
Isolate b (the y-intercept):
-3 = -5 + b
b = 2
y = 5/4x + 2

The finish line is 253 m away. You begin to run from rest. You must reach a velocity of 53.2 m/s or you will explode. What must your acceleration be?
The acceleration require for the body to not explode will be 0.2941[tex] m/s^2 [/tex]
The finish line as given is 253m away so that distance to be covered will be 253m.
Also we had started to run from rest so that initial velocity will be 0m/s.
We should take care that we could not explode and this is possible only if we reach to the velocity of 53.2m/s. So our final velocity will be 53.2m/s.
Now average velocity will be the sum of initial velocity and final velocity divided by 2.
∴ Average velocity = (initial velocity + final velocity) / 2.
∴ Average velocity = (0 + 53.2) / 2 = 53.2 / 2 = 26.6m/s
As we know that average velocity will give us an average time of the run by formula average speed = distance / average time.
∴ Average time = distance / average speed
∴ Average time = 253 / 26.6 = 9.51s.
Now as we know by the formula to calculate acceleration we need the average velocity, average time and we have both of them.
∴ Acceleration = [tex] \frac{average\ velocity}{(average\ time)^2}[/tex]
∴ Acceleration = [tex] \frac{26.6}{(9.51)^2}[/tex]
∴ Acceleration = [tex] \frac{26.6}{90.44}[/tex]

What are the coordinates of the point on the directed line segment from (3,−3) to (7,5) that partitions the segment into a ratio of 5 to 3
The coordinates along the directed line segment is (37/7, 11/7)
How to find the coordinates of the point?The points are given as:
A = (3, -3)
B = (7, 5)
The ratio on the segment can be represented as;
m : n = 4 : 3
So, we have the coordinates of the point that lies along the directed line segment to be
Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)
So, we have:
Point = 1/(4 + 3) * (4 * 7 + 3 * 3, 4 * 5 + 3 * -3)
Evaluate
Point = 1/7 * (37, 11)
Evaluate the products
Point = (37/7, 11/7)
Hence, the coordinates of the point is (37/7, 11/7)
