Answer:
The gradient of the line segment between the points (1,-1) and (3,-13) is -6
Step-by-step explanation:
The gradient of the line segment between the points (1,-1) and (3,-13) is -6
Step-by-step explanation:
We need to find the gradient of the line segment between the points (1,-1) and (3,-13)
The gradient is basically the slope of line.
The formula used to calculate slope\gradient is: Slope=\frac{y_2-y_1}{x_2-x_1}\\
We have x_1=1, y_1=-1, x_2=3, y_2=-13
Putting values and finding slope
Slope=\frac{y_2-y_1}{x_2-x_1}\\\\Slope=\frac{-13-(-1)}{3-1} \\Slope=\frac{-13+1}{2} \\Slope=\frac{-12}{2}\\Slope=-6
So, gradient of the line segment between the points (1,-1) and (3,-13) is -6

Doctors sometimes use this formula to calculate how much medicine to give a child. A child who is 4 years old needs some medicine. The amount for an adult is 20 ml. Use the formula to work out the correct amount for this child.
Answer:
A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity
Step-by-step explanation:
Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.
...
Example 2.
Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day
Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose

A computer costs $800. It loses ¼ of its value every 2 years after it is purchased.
How much will the computer be worth in 6 years?
The computer will be worth $200.
Step-by-step explanation:
A quarter of $800 is $200, so the computer loses $200 dollars in value every two years. Since 6÷2 is 3, you multiple $200 by 3 to get $600. You then subtract $600 from $800 and get $200.
Answer: The value of the computer at time 0 is $800
The value of the computer at time 1 is $600
The value of the computer at time 2 is $450
The value of the computer at time 3 is $337.50
The value of the computer at time t is (n - 1) x 3/4

Write 2 41/50 as a percent
Answer:
282%
Step-by-step explanation:
2 and 41/50 is also 82/100 so 282%
The mixed number A = 2 41/50 as a percentage is P = 282 %
Given data ,
Let the percentage value be represented as P
Now , the mixed number is given as A
where the value of A = 2 41/50
On simplifying the number , we get
A = 2 82/100
where the conversion of a fraction to a percent, we divide the numerator by the denominator and multiply by 100.
(141/50) x 100 = 282/1
On simplifying the equation , we get
P = 282%
Therefore, 2 41/50 is equal to 282%
Hence , the percentage value is A = 282 %

Step-by-step explanation:
These triangles can be proven congruent through AAS, or angle, angle, side. This means that two angles and one nonincluded side are congruent. Two sides are marked as congruent through a tick mark, and one angle pair is marked by one arc on each angle. We also know that the middle angles, that are connected, are congruent because they are vertical angles. Therefore, they are congruent, which can be proven by AAS.

Consider all positive integers that are multiples of 10 and are less than or equal to 200. What fraction of those integers are multiples of 15?
A. 1/20
B. 3/20
C. 3/10
D. 2/5
E. 3/4
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Consider all positive integers that are multiples of 10 and are less than or equal to 200.
Let the number of the positive integer that are multiples of 10 be x. Then the equation will be
10x ≤ 200
Then the value of the x will be
x ≤ 20
The set of numbers is given below.
Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}
The set which is divisible by 15 will be
Set = 6 {30, 6,0 90, 120, 150, 180}
Then the fraction of those integers are multiples of 15 will be
⇒ 6 / 20
⇒ 3/10
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

a. How far is the spot on the beach from the parking lot?
b. How far will he have to walk from the parking lot to get to the refreshment stand?
Show work please.
The altitude of the right triangle is the geometric mean of the 2 parts of the side it separates.
a. The answer would be sqrt(18*32)=24
The question to the second question can be answered by using the Pythagorean theorem.
32^2+24^2=1600=40^2
b. The answer would be sqrt40^2=40
The beach, the parking lot and the refreshment stand are illustrations of similar triangles.
The distance between the spot and the parking lot is 24 mThe distance between the refreshment stand and the parking lot is 40 m(a) The distance between the spot and the parking lot
Represent this distance with d.
So, the equivalent ratio is:
[tex]\mathbf{32:d = d : 18}[/tex]
Express as fractions
[tex]\mathbf{\frac {32}d = \frac{d}{ 18}}[/tex]
Cross multiply
[tex]\mathbf{d \times d = 32 \times 18}[/tex]
[tex]\mathbf{d^2 = 576}[/tex]
Take square roots
[tex]\mathbf{d = 24}[/tex]
Hence, the distance between the spot and the parking lot is 24 m
(b) The distance between the refreshment stand and the parking lot
Represent this distance with d.
Using Pythagoras theorem we have:
[tex]\mathbf{d^2 = 32^2 + 24^2}[/tex]
[tex]\mathbf{d^2 = 1600}[/tex]
Take square roots
[tex]\mathbf{d = 40}[/tex]
Hence, the distance between the refreshment stand and the parking lot is 40 m
