Hudson and Knox are in a race. Hudson is running at a speed of 8.8 feet per second. Knox got a 30-foot head start and is running at a speed of 6.3 feet per second. How many seconds will it take until Hudson and Knox have run the same number of feet? Write the equation.
Answer:
It will take 12 seconds to be at same distance
The equation is;
8.8x = 6.3x + 30
Step-by-step explanation:
Let the number of seconds it will take be x
Mathematically, distance = speed * time
At x-seconds , Hudson will be at a distance of 8.8 * x = 8.8x ft
At x seconds , Knox will be at a distance of 30 ft + (6.3 * x) = 6.3x + 30feet
So the time it will take them to be at the same distance can be calculated using the equation;
6.3x + 30 = 8.8x
8.8x - 6.3x = 30
2.5x = 30
x = 30/2.5
x = 12 seconds
Answer:
Step-by-step explanation:
It will take 12 seconds to be at same distance
A regular pentagon and rectangle have the same perimeter. The length of the rectangle and the side of the pentagon are equal. The width is 10 more than the length. Write an equation that describes the scenario. pentagon's perimeter: rectangle's perimeter: scenario's equation:
Answer:
Pentagon perimeter 5l
Rectangle perimeter 2l +2(l + 10
Scenario’s equation 5l=2l +2(l + 10)
Step-by-step explanation:trust me
The equation that describes the pentagon perimeter is 5l
Where l is the sides of the pentagon.
The equation that describes the rectangular perimeter is 4l + 20
Where l is the length of the rectangle
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Regular pentagon:
A regular pentagon has 5 sides.
Side = l
Rectangle:
Length = l
Width = 10 + l
Now,
The perimeter of a pentagon = 5 side
The perimeter of a rectangle = 2 (l + w)
The perimeter of the pentagon.
= l + l + l + l + l
= 5l
The perimeter of the rectangle.
= 2 (l + w)
= 2 (l + 10 + l)
= 2 (2l + 10)
= 4l + 20
Thus,
The equation that describes the pentagon perimeter is 5l
Where l is the sides of the pentagon.
The equation that describes the rectangular perimeter is 4l + 20
Where l is the length of the rectangle

answers to unit 1 geometry basics homework 4 angle addition postulate
Answer:
EF = 58
Step-by-step explanation:
Find the diagram of the question attached.
According to the addition postulate;
DE+EF = DF
Given
DE = 47
EF = 3x+10
DF = 9x-39
Substitute into the addition postulate formula and get x
47+3x+10= 9x-39
Collect like terms
3x-9x = -39-10-47
-6x = -96
x = -96/-6
x = 16
Next is to evaluate EF:
EF = 3x+10
EF = 3(16)+10
EF = 48+10
EF = 58
Hence the measure of EF is 58
1 ≤ x + 7 < 7
explain how u got the answer plz
Answer:
-6 ≤ x < 0
Step-by-step explanation:
Subtract the 7 on both sides to get x isolated.
Answer:
-6 ≤ x < 0
Step-by-step explanation:
This is the answer because:
1) First, we have to isolate the x
2) In order to isolate the x, you have to subtract 7 from 1 and 7
1 - 7 = -6
7 - 7 = 0
Therefore, the inequality is -6 ≤ x < 0

Cypress Middle School wants to have a fundraiser to buy art supplies. Fundraiser A will give the school $1.50 for each order places plus $75 as a bonus. Fundraiser B will give the school $3.00 for each order placed, but no bonus. How many orders must be placed in order for the total amount of money earned by each fundraiser to be the same?
150
Answer:
The indifference point is 50 orders.
Step-by-step explanation:
Giving the following information:
Fundraiser A:
$1.50 for each order places plus $75 as a bonus.
Fundraiser B:
$3.00 for each order placed.
First, we need to structure the fundraisers' formula:
Fundraiser A= 75 + 1.5x
Fundraiser B= 3x
x= number of orders
Now, we equal both formulas and isolate x:
75 + 1.5x = 3x
75/1.5= x
50= x
The indifference point is 50 orders.
Prove:
Fundraiser A= 75 + 1.5*50= $150
Fundraiser B= 3*50= $150

question: What is the slope of the line?
Answer:
4/5
Step-by-step explanation:
If you look at the point (-2,0) you can see that it sits directly on the line above 2. If you also at the point (3,4) you can see that its also sitting directly in the middle, where the line runs through it. Using this information we can use Rise/Run.
Rise/Run = Y/X
from (-2, 0) you rise 4 and you run 5 to the right to land on (3,4).
This is one of many ways you can calculate The slope from a graph!

Let numerator of fraction be x and denominator be y.
∴ Fraction = x/y
★ Part - A :
[tex]:\implies\tt\:\dfrac{x\times 4}{y-2}=2[/tex]
[tex]:\implies\tt\:4x=2(y-2)[/tex]
[tex]:\implies\tt\:4x=2y-4[/tex]
[tex]:\implies\tt\:2y=4x+4[/tex]
[tex]:\implies\bf\:y=2x+2\:\:\dots (1)[/tex]
★ Part - B :
[tex]:\implies\tt\:\dfrac{x+15}{2y-2}=\dfrac{9}{7}[/tex]
[tex]:\implies\tt\:7(x+15)=9(2y-2)[/tex]
[tex]:\implies\tt\:7x+105=18y-18[/tex]
From equation (1)...

[tex]:\implies\tt\:y=2(3)+2[/tex]
[tex]:\implies\boxed{\bf{y=8}}[/tex]
∴ Fraction = x/y = 3/8
Hope It Helps!Answer: 3/8
Step-by-step explanation:
Let x represent the numerator and y represent the denominator.
Equation 1: (4x)/(y - 2) = 2
4x = 2(y - 2) Cross Multiplied
4x = 2y - 4 Distributed
4x - 2y = -4 Subtracted 2y from both sides
Equation 2: (x + 15)/(2y - 2) = 9/7
9(2y - 2) = 7(x+15) Cross Multiplied
18y - 18 = 7x + 105 Distributed
-7x + 18y - 18 = 105 Subtracted 7x from both sides
-7x + 18y = 123 Added 18 to both sides
Solve the system of equations using Elimination Method:
EQ1: 4x - 2y = -4 → 9(4x - 2y = -4) → 36x - 18y = -36
EQ2: -7x + 18y = 123 → 1(-7x + 18y = 123) → -7x + 18y = 123
29x = 87
÷29 ÷29
x = 3
Substitute x = 3 into either equation to solve for y:
EQ1: 4x - 2y = -4
4(3) - 2y = -4
12 - 2y = -4
-2y = -16
y = 8
The numerator (x) = 3
The denominator (y) = 8
The fraction is: 3/8
