Answer:
3
Step-by-step explanation:
A ratio is always expressed in the form a : b = a / b ; where, a = antecedent ; b = consequent
With antecedent = 15 ; consequent = b
Value of ratio = 5
15 / b = 5
Cross multiply
15 = 5b
b = 15 / 5
b = 3

Consider the LD50 of Drug X above. Draw a vertical dashed line starting at 10 mg/kg on the x-axis and ending on the graphed line. Draw a horizontal line starting at 50% on the y-axis and ending on the graphed line. This is the LD50 of Drug X. What is the LD50 of Drug X
Solution :
LD50 is a test that used by the scientist and by the medical practitioners to determine the toxicity of any chemical compounds. It involves introducing the different dose levels of the chemical compound that is to be tested to the group of the experimental subjects.
The LD50 graph of the Drugs X is attached below.
From the graph, we can see that the LD50 level of the drug X is 10 mg/kg.
(x - 2)(x + 1) = 3x - 2
Answer:
x=4
Step-by-step explanation:
(x-2)(x+1)=3x-2
x(x+1)-2(x+1)=3x-2
x^2+x-2x-2=3x-2
x^2-x-2=3x-2
x^2=3x+x-2+2
x^2=4x
x^2/x=4
x=4
(x - 2) ( x + 1) = 3x - 2
x² + x - 2x - 2 = 3x - 2
x² + x - 2x - 2 - 3x + 2 = 0
x² - 4x = 0
x ( x - 4 ) = 0
x - 4 = 0/x
x - 4 = 0
x = 4
Alicia borrowed $15,000 to buy a car. She borrowed the money at 8% for 6 years
Answer:
She have to pay the bank at the end of the 6 years = 222000$
Step-by-step explanation:
Formula applied in this case where price, interest rate and time duration is mentioned.
Interest = prt/100
Substituting all the given values in the formula.
interest = 15000 * 6 * 8/100
150 * 6 * 8 = 7200
Interest + 15000 = 15000 + 7200 = 222000$ has to pay the total.
In this question amount is 15000 multiply by 6 and by 8 then divide it by 100 so we get the interest then we add it in to amount so we get an answer that is total amount which he has to pay. Hope this helps! :P PLZ GIVE ME BRAINLIST

The solution for the first expression is 110592. The solution of the second expression is 72.
In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
Using these rules, we can simplify the expressions as follows:
E = 6³ x 2⁶ x 2³
E = 6³ * 2⁶⁺³
E = 6³ x 2⁹
E = 216 x 512
E = 110592
Therefore, the first expression is equal to 110592.
To simplify the second expression, we can simply evaluate 2^6 and 2^3 and add the results:
E = 2⁶ + 2³
E = 64 + 8
E = 72
Therefore, the second expression is equal to 72.

A square garden plot has an area of 75 ft. a. Find the length of each side in simplest radical form. b. Calculate the length of each side to the nearest
tenth of a foot.
9514 1404 393
Answer:
a. 5√3 ft
b. 8.7 ft
Step-by-step explanation:
The area is the square of the side length, so the side length is the square root of the area:
s = √A
s = √(75 ft²) = √(25·3 ft²) = √(3·(5 ft)²)
s = 5√3 ft ≈ 8.7 ft . . . . . . side length of garden

What is 2 to the 5th power?
Step-by-step explanation:
2 to the 5th power =2⁵=2×2×2×2×2=32
The value of 2 to the 5th power (2⁵) is equal to 32.
To calculate 2 to the power of 5 (2⁵).
We have to multiply the base number (2) by itself for the number of times specified by the exponent (5).
So, 2⁵ can be calculated as:
2 × 2 × 2 × 2 × 2
= 32
Therefore, 2 to the 5th power (2⁵) is equal to 32.

Answer:
(a) 5/6
Step-by-step explanation:
Positive numbers are greater than negative ones.
Fractions with the same denominator are greater if their numerator is greater.
All of these fractions have the same denominator. Because 5 > 1 > -1 > -5, the ordering of the fractions is ...
5/6 > 1/6 > -1/6 > -5/6
The fraction with the greatest value is 5/6.

2) Identify the foci and asymptotes
3) find the domain and range
Answer:
Example: Locating a Hyperbola's Vertices and Foci
The hyperbola is centered at the origin, so the vertices serve as the y-intercepts of the graph. To find the vertices, set x=0 x = 0 , and solve for y y . Therefore, the vertices are located at (0,±7) ( 0 , ± 7 ) , and the foci are located at (0,9) ( 0 , 9 ) .

if the sum of interior angles of polygon is 1800
Answer:
12 sides
Step-by-step explanation:
Given
[tex]Sum =1800^o[/tex]
Required
The number of sides of the polygon
The sum of interior is calculated using:
[tex]Sum = 180 * (n - 2)[/tex]
Where
[tex]n \to[/tex] number of sides
So, we have:
[tex]Sum = 180 * (n - 2)[/tex]
[tex]1800 = 180 * (n - 2)[/tex]
Divide both sides by 180
[tex]10 = n - 2[/tex]
Add 2 to both sides
[tex]12= n[/tex]
[tex]n=12[/tex]

In ΔQRS, the measure of ∠S=90°, RQ = 41, QS = 9, and SR = 40. What is the value of the cosine of ∠R to the nearest hundredth?
Answer:
cos R = .98
Step-by-step explanation:
cos R = SR/QR
QR is the hypotenuse of the right triangle. By the Pythagorean theorem
(QR)^2 = (QS)^2 + (SR)^2
= 9^2 + 40^2
= 81 + 1600
= 1681
QR = 41
Cos R = adjacent side/hypotenuse = 40/41 = .98
The value of the cosine of ∠R to the nearest hundreth is 0.98.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
The sides can also be found using pythagoras theorem. Therefore,
∠S = 90°
RQ = 41
QS = 9
SR = 40
cos R = adjacent / hypotenuse
Therefore,
adjacent side = 40
hypotenuse = 41
cos R = 40 / 41
cos R = 0.97560975609
cos R = 0.98
