The length of the base of an isosceles triangle is x. The length of a leg is 5x – 3. The perimeter of the triangle is 60. Find x.
X
Answer: x = 6
Step-by-step explanation:
The perimeter of the isosceles triangle = 2 leg + base
Since the perimeter = 60
then 60 = 2(5x - 3) + x
60 = 10x - 6 + x
60 + 6 = 11x
6 = x

How long will it take for a $2000 investment to grow to $2786 at an annual rate of 4.6% , compounded quarterly? Assume that no withdrawals are made.
Answer:
7.4
Step-by-step explanation:
use the compound interest formula
I=P(1+r/100)<n
2786=2000(1+4.6/100)^n
divide 2000 by both side
1.393=(1+4.6/100)^n
1.393=1.046^n
introduce the log
log1.393=rlog1.046
divide both with log1.046 to get the value of n
n=7.4
Nyesha owns a lawn service company. Currently it takes her 50 hours a week to service all of her
customers. To reduce the number of hours a week she needs to work, Nyseha hires Shantese to
help her. While Nyesha was on vacation, Shantese was able to complete all of the work in 60 hours.
If Shantese and Nyesha work together, after Nyesha returns from facation, how long will it take
them to service all their customers?
Fractions are integers that have both a numerator and a denominator. They are represented as; [tex]\frac{x}{y}[/tex]
Where:
x = Numerator
y = Denominator.
To solve the above question, we would be applying the operations of the addition of fractions.
It will take both of them [tex]27\frac{3}{11}[/tex] hours if they worked together.
From the question,
Nyesha takes 50 hours a week to render services to her customers.
Shantese takes 60 hours a week to do the same amount of work.
Let us represent the number of hours it will take them both to decorate the room working together as "T"
Hence,
1/T = 1/50 + 1/60
Lowest Common Denominator for (50, 60 ) = 300
Hence,
1/T = 6 + 5 / 300
1/T = 11/300
Find the reciprocal of both sides
T = 300/11 hours
T = [tex]27\frac{3}{11}[/tex] hours
Therefore, it will take them both of them [tex]27\frac{3}{11}[/tex] hours in they both work together.

Find the equation in slope-intercept form of the line parallel to y = 4x + 23 and passes through the point (2,3).
Answer: y=4x-5
Step-by-step explanation:
The slope of y=4x+23 is:4 m=4
The parallel line needs to have the same slope of 4
Solve it using the "point-slope" equation of a line: y− y1 = 2(x − x1)
substitute or put in the point (2,3):
y − (3) = 4(x − 2)
y - 3 = 4x - 8
put it in slope intercept form y = mx + b
y = 4x − 5

A model of a building is 18 inches tall. If the building is really 678 feet tall, how tall is a window that is 1/9 in on the model? Round to the nearest tenth if needed.
Answer:
50.2in or 4.2ft
Step-by-step explanation:
This is a problem about proportions so I generally set up my problems like below. I just set some variable here to make it easier to refer back to the measurements for each. You don't have to do this, I am just showing it for clarity. I will convert everything to inches too. We need to find the real window height.
Mb = model building = 18in
Mw= model window = [tex]\frac{1}{9}[/tex]in
Rb = real building = 678ft = 8136in
Rw = real window = ?
[tex]\frac{Mw}{Mb}[/tex] = [tex]\frac{Rw}{Rb}[/tex]
[tex]\frac{1/9}{18}[/tex] = [tex]\frac{Rw}{8136}[/tex]
[tex]\frac{1}{9*18}[/tex] = [tex]\frac{Rw}{8136}[/tex]
[tex]\frac{1}{162}[/tex] = [tex]\frac{Rw}{8136}[/tex]
[tex]\frac{1*8136}{162}[/tex]= [tex]\frac{8136*Rw}{8136}[/tex]
[tex]\frac{8136}{162}[/tex] = Rw
[tex]\frac{452}{9}[/tex] = Rw
Rw ≈ 50.2in ≈ 4.2ft

What are the three trigonometric reciprocals of sine, cosine, and tangent?
Answer:
Secant, cosecant and cotangent.
Step-by-step explanation:
Step-by-step explanation:
There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

4) Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each
session. If Allison has already practiced 3 hours this week, how many more sessions remain for her to meet
or exceed her weekly practice goal?
Answer:
12
Step-by-step explanation:
So, she practices 12 hrs per week, and already has practiced 3 hrs this week.
This means she has 9 hrs left to practice.
3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)
which is basically 9 / ( 3/4)
[tex]\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12[/tex]
She needs 12 more sessions.

Maggie has a bank account balance of -18.37 as soon as she realizes this she deposits 24.50 in the account
Answer:
correct the answer is 6.13
Step-by-step explanation:
The required current balance in Maggie's bank account is 6.13.
Given that,
Maggie has a bank account balance of -18.37 as soon as she realizes this she deposits 24.50 in the account.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
here,
initial balance in Maggies's bank account = -18.37
She deposited 24.50 in her bank account,
The current balance in her bank account = Initial balance + money deposited
Current = 24.50 - 18.37
Current balance = 6.13
Thus, the required current balance in Maggie's bank account is 6.13.

For the standard normal distribution, the area between z = 0 and z = 1.70, rounded to four decimal places, is:
Using normal distribution table, the area between z=0 and z=1.70 is the difference between p(z=0) and p(z=1.70). Hence, the area between z=0 and z = 1.70 is 0.4554
Using a normal distribution table :
P(Z < 0) = 0.5 P(Z < 1.70) = 0.95543The Area between z=0 and z= 1.70 is defined as the difference between the probabilities of (z < 1.70) and (z < 0)
P(Z < 1.70) - P(Z < 0) = 0.95543 - 0.5 = 0.45543
Therefore, the area between z = 0 and z = 1.70 rounded to four decimal places is 0.4554
