Tim is 4% of Moby so
T =4%m
if T is for Tim and Tim weighs 50kgs then
50=4%m
100/4=25
25*50=1250
M = 1250Kgs

If you are solving the equation 1/(x-4)+1=14/(x+2) by factoring, which of the following equations would you use the zero product property on?
(x - 5)(x + 4) = 0
(x - 5)(x - 10) = 0
(x + 5)(x + 10) = 0
Answer:
The equation that would be used for the zero product property on will be (x-5)(x-10)=0
Option B is correct.
Step-by-step explanation:
We need to solve the equation [tex]\frac{1}{(x-4)}+1=\frac{14}{x+2}[/tex]
Solving the equation:
[tex]\frac{1}{(x-4)}+1=\frac{14}{x+2}\\\frac{1+(x-4)}{x-4}= \frac{14}{x+2}\\\frac{1+x-4}{x-4}= \frac{14}{x+2}\\\frac{x-3}{x-4}= \frac{14}{x+2}\\Cross\: Multiply\\(x-3)(x+2)=14(x-4)\\x(x+2)-3(x+2)=14x-56\\x^2+2x-3x-6=14x-56\\x^2-x-6-14x+56=0\\x^2-x-14x-6+50=0\\x^2-15x+50=0[/tex]
Now, we would factorise to find value of x
[tex]x^2-15x+50=0\\x^2-5x-10x+50=0\\x(x-5)-10(x-5)=0\\(x-5)(x-10)=0[/tex]
So, the equation that would be used for the zero product property on will be (x-5)(x-10)=0
Option B is correct.
Answer:
So, the equation that would be used for the zero product property on will be (x-5)(x-10)=0
Option B is correct.

If ris the radius of a circle and dis its diameter, which of the following is an
equivalent formula for the circumference C= 2?
Answer:
D is the answer.
Step-by-step explanation:
The equivalent formula for the circumference C is,
⇒ C = πd
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
r is the radius of a circle and d is its diameter,
We know that;
The circumference of circle is,
C = 2πr
Where, 'r' is radius of circle
Now, We know that;
⇒ r = d / 2
Hence, We get;
The equivalent formula for the circumference C is,
⇒ C = 2π × d/2
⇒ C = πd
Thus, The equivalent formula for the circumference C is,
⇒ C = πd

The area of a triangular wedge is 90 square inches. The height is 18 inches.
What is the base2
Hello!
[tex]\large\boxed{b = 10in}[/tex]
Formula for the area of a triangle:
A = 1/2(bh)
We are given the height and area, so we can plug those into the formula to solve for b:
90 = 1/2(18b)
Multiply both sides by 2:
180 = 18b
Divide both sides by 18:
b = 10 inches.
Answer:
10inches is equal to the base
Step-by-step explanation:
formula for finding the area of a triangle is
½bh which is half times base times height
-base is unknown, height is 18 and area is 90.
-½x*18=90
½of 18 is 9
1x*9=90
9*x=9x
therefore:9x=90
we devide both sides by the co-efficient of x which is 9
9 dividing 90 is 10.
therefore x is equal 10

The equation would be 9x=y
Step-by-step explanation:
The equation for the counselor and the camper will be y = 9x
What is an equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
At a summer camp, there is one counselor for every 9 campers.The equation will be formed as:-
The number of campers, y, that there is for x counselors so equation will be given as.
Y = 9x

Anyone plz help me asap!
Answer:
x = 9
Step-by-step explanation:
According to the midsegment theorem,
HG = ½(QS)
Thus:
21 + 2x = ½(2x + 24)
Multiply both sides by 2
2(21 + 2x) = 2x + 24
42 + 4x = 2x + 24
Collect like terms
42 - 24 = 2x - 4x
-18 = -2x
Divide both sides by -2
9 = x
x = 9

Answer:
[tex]z^{4} = \cos \frac{8\pi}{3}+i\,\sin \frac{8\pi}{3}[/tex]
Step-by-step explanation:
We can determine the power of a complex number by the De Moivre's Theorem, which states that for all [tex]z = r\cdot (\cos \theta + i\,\sin\theta)[/tex], where [tex]a, b \in \mathbb{R}[/tex], the power of the complex number is:
[tex]z^{n} = r^{n}\cdot (\cos n\theta + i\,\sin n\theta)[/tex] (1)
Where:
[tex]r[/tex] - Magnitude of the complex number, dimensionless.
[tex]\theta[/tex] - Direction of the complex number.
If we know that [tex]r = 1[/tex], [tex]n = 4[/tex] and [tex]\theta = \frac{2\pi}{3}[/tex], then the fourth power of the complex number is:
[tex]z^{4} = 1^{4}\cdot \left[\cos\left(\frac{8\pi}{3} \right)+i\,\sin\left(\frac{8\pi}{3}\right)\right][/tex]

6x + 14y = 32
6x - 14y = 4
The solution is ___ ( simplify your answer. Type an ordered pair.)
Answer:
x = 3 and y = 1
Step-by-step explanation:
The given equations are :
6x + 14y = 32 ...(1)
6x - 14y = 4 .....(2)
Add equation (1) and (2) :
6x + 14y + 6x - 14y = 32 + 4
12x = 36
x = 3
Put the value of x in equation (1)
6(3) + 14y = 32
18 + 14y = 32
14y = 32-18
14y = 14
y = 1
Hence, the value of x is 3 and y is 1.
Question
Tim has an investment account that compounds interest continuously at a rate of 1.6%. After 5 years, he has $2400 in the
account.
How much money did he initially place in the account?
Round your answer to the nearest dollar.
Answer:
$2215
Step-by-step explanation:
The formula for continuous compound interest is P(t) = P₀[tex]e^{rt}[/tex].
$2,400 = P₀e⁽¹⁻⁰¹⁶⁾⁽⁵⁾
Divide both sides by (e⁽¹⁻⁰¹⁶⁾⁽⁵⁾) to isolate the initial amount:
($2,400) ÷ e⁽¹⁻⁰¹⁶⁾⁽⁵⁾ = (P₀e⁽¹⁻⁰¹⁶⁾⁽⁵⁾) ÷ e⁽¹⁻⁰¹⁶⁾⁽⁵⁾
$2,400 ÷ e⁽¹⁻⁰¹⁶⁾⁽⁵⁾ = P₀
Solve:
$2,400 ÷ e⁽¹⁻⁰¹⁶⁾⁽⁵⁾ = $2215.48
P₀ = $2215.48
P₀ = $2215

A company makes a bracelet that is designed to repel mosquitoes so people don't have to wear bug spray. Researchers at the company are designing an experiment where volunteers will be assigned either the bracelet or bug spray to use at their homes. The researchers want to use a randomized block design. How should the researchers form the blocks
Answer: volunteer within each block should live in similar environments to each other when it comes to mosquitos
Step-by-step explanation:
The researchers using a randomized block design should form the blocks by making the;
Volunteers within each block should live in similar environments to each other when it comes to mosquitos.
A randomized block design is simply a type of experiment where the experimental units are put in groups known as blocks.
Now, we are told that;
- A company is designing an experiment where volunteers will be assigned either the bracelet or bug spray to use at their homes.
- They are doing the experiment because they want to make a bracelet that can repel mosquitoes so people don't have to wear bug spray anymore.
Now, this implies that the environment they find themselves has a big impact on the outcome of the experiment. This is because different environments could have different exposure conditions to mosquitoes and as a result it will be better for them to be within the same environment for better experimental results.
