Answer:
simplest form
Step-by-step explanation:
Simplest form is a method of converting the fraction to its lowest multiple.
For example, the fraction 25/100 isn't in its simplest form
Both the numerator and the denominator can be divided by 5. When divided by 5 the fraction becomes 5/20.
5/20 is still not in its simplest form because it can be divided by 5. When divided by 5, the fraction becomes 1/4.
1/4 is now in its simplest form because both the numerator and denominator cannot be divided by any other number
Joel has a goal to practice his clarinet for 4 hours per week. The list 5 1below shows the number of hours Joel has practiced so far this week. Monday 1 hours 2 1 Wednesday 1 hours 3 1 Thursday 1 hour How many more hours does Joel need to practice this week to meet his goal?
Answer:
Joel need to practice this week = [tex]\frac{3}{4}[/tex] hour
Step-by-step explanation:
P.S - the exact question is -
As given
Total practice goal of Joel = [tex]4\frac{1}{2}[/tex] hours
He practiced on : Monday - [tex]1\frac{1}{2}[/tex] hours
Wednesday - [tex]1\frac{1}{4}[/tex] hours
Thursday - 1 hour
Let the remaining practice = x hours
⇒ Total practice = [tex]4\frac{1}{2}[/tex] hours
⇒[tex]1\frac{1}{2}[/tex] + [tex]1\frac{1}{4}[/tex] + 1 + x = [tex]4\frac{1}{2}[/tex]
⇒ 1 + [tex]\frac{1}{2} + 1 + \frac{1}{4} + 1 + x = 4 + \frac{1}{2}[/tex]
⇒3 + x - 4 = [tex]\frac{1}{2} - \frac{1}{2} - \frac{1}{4}[/tex]
⇒x - 1 = [tex]-\frac{1}{4}[/tex]
⇒x = [tex]-\frac{1}{4} + 1 = \frac{-1 + 4}{4} = \frac{3}{4}[/tex]
⇒x = [tex]\frac{3}{4}[/tex] hour
∴ we get
Joel need to practice this week = [tex]\frac{3}{4}[/tex] hour

A telephone pole is 54 feet tall. A guy wire runs 79 feet, from point A at the top of the telephone pole, to the ground at point B. The base of the telephone pole is at point C. Triangle ABC is a right triangle.
How far is it from the base of the telephone pole to point B where the guy wire is secured to the ground? Round to the nearest tenth of a foot.
ft
Answer:
57.7 ft
Step-by-step explanation:
54 squared + b squared = 79 squared
2916 + b squared = 6241
-2916 -2916
b squared = 3325
b = 57.7

The distance that the base of the telephone pole to point B where the guy wire is secured to the ground is 57.7 feet
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Given that triangle ABC is a right triangle.
Point A is the top of the telephone pole.
Point B is the point on the ground.
Point C is the base of the telephone pole.
Given,
AB = 79 feet
AC is the height of the telephone pole = 54 feet
Angle C is a right angle.
Using Pythagoras theorem,
(AB)² = (AC)² + (BC)²
79² = 54² + (BC)²
(BC)² = 79² - 54²
(BC)² = 3325
BC = √3325 = 57.66 ≈ 57.7 feet
Hence the length of the base of the pole form the ground where the wire is secured is approximately 57.7 feet.

What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Let x be the number of bass and y be the number of trout.
Each bass weighed 3 pounds, and each trout weighed 1 pound. Pat caught a total of 30 pounds of fish.
So, 3x+y=30 --------(I)
Since trout are endangered in Lake Pisces, he lost 1 point for each trout. Pat scored a total of 42 points.
5x-y=42 --------(II)
Use elimination method
Add equation (I) and (II), we get
3x+y+5x-y=30+42
⇒ 8x=72
⇒ x=9
Put x=9 in equation (I), we get
3(9)+y=30
⇒ y=3
Hence, the number of bass are 9 and the number of trout are 3.

The Grade 5, 6 and 7 classes are putting on a talent show. Fifty percent of
the participants are from Grade 6 and 0.3 of the participants are from
Grade 5. What is the fraction of participants from Grade 7
Answer:
Here's how to solve the problem
Step-by-step explanation:
50% of participants are in 6th grade.
100% - 50% = 50
0.3, when converted to percentage form is 30%
50% - 30% = 20%
This remaining 20% is how many participants, out of the whole, are in the 7th grade
20% = 0.2 = 2/10 = 20/100

I have no idea how to explain I did it on paper but if you look up how to divide fractions it‘ll show you how and that’s how you get your answer or use a calculator.
1. turn 1 1/5 into an improper fraction = 6/5
this is how it should go :
1 1/5 divided by 3/4
1 1/5 turns into 6/5
3/4 divide 6/5
and after that you jus keep going and if you don’t know how to divide fractions look it up and it should show you.
The sum of the mixed fraction number 1 ¹/₅ and the fraction number 3/4 will be 39/20.

what is 3x+12= 42
Answer:
x is 10.
Step-by-step explanation:
3x + 12 = 42
Subtract 12 from both sides
3x = 42 - 12
Subtract 12 from 42 to get 30
3x = 30
Divide both sides by 3
x = 30/3
Divide 30 by 3 to get 10

He receives 2.5% per year simple interest.
How much will Dan have after 4 years ?
Answer:
$16,557
Step-by-step explanation:
The computation of the amount after four years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years

Kaydence and Delilah are playing mini golf. Delilah's final score was 42. In mini golf, the player with the lowest score wins. Kaydence has 5 holes left and has a score of 27. This inequality represents x, the average number of shots she can take on each hole in order to beat Delilah's score. Which inequality shows how many shots she can take on each hole, on average, in order to beat Delilah's score? A. X < 3 B. X < 4 C. X < 10 D. X < 5
Answer:
A. X < 3
Step-by-step explanation:
Let x represent the average number of shots Kaydence can take on each hole in order to beat Delilah's score.
Delilah final score is 42 while Kaydence has 5 holes left and has a score of 27. Hence:
number of holes left for Kaydence * x < Delilah final score - Kaydence present score
That is:
5*x < 42 - 27
Simplifying gives:
5x < 15

Elimination equations
9x - 4y = 19
4x+4y=20
The solution to the system of equations 9x - 4y = 19 and 4x + 4y = 20
is x = 3 and y = 2.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear.
Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, Two linear equations in two variables 'x' and 'y',
9x - 4y = 19 and 4x + 4y = 20.
Now, Adding these two equations we have,
13x = 39.
x = 3 and hence y = 2.
