Answer:
54minutes
Step-by-step explanation:
Let the time taken to clean up be t
Let the number of people cleaning be n
If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;
t = k/n
k is the constant of proportionality
If 3 people work together to clean, and took them 90 minutes, this means
at t = 90, n=3
Substitute
90 = k/3
k = 3×90
k = 270
To et the time it will take 5people to clean, the will say;
t =k/n
t =270/5
t = 54 minutes
Hence it will take 5 people 54minues to clean
Answer: 54 minutes

slope for (1 -2) (3 3)
Answer:
[tex] \frac{5}{2} [/tex]
Step-by-step explanation:
The formula for slope is (y₂-y₁)/(x₂-x₁)
Which means the (y) from the Second ordered pair subtract (y) from the 1st ordered pair, then divide by (x) from the second ordered pair, minus the (x) from the first.
So (3-(-2))/(3-1)

Write the equation of the line with slope 2/3 passing through (6,5) in slope-intercept form.
Answer:
2 = (2/3)*(6)+b
2 = 4+b
b= -2
so slope intercept form is y = (2/3)x -2
To find the point slope form, simply plug in m and the point given.
y-2 = (2/3)*(x-6)

If a frustrated student kicks a wall with 100N force, and does not break, how much force does
the wall respond with?
Answer:
100n back i guess
Step-by-step explanation:
rip kids foot
The force exerted by the wall on the student's foot if the student kicks a wall with 100 N force, is 100 N.
What is force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Given:
A student kicks a wall with 100 N force,
As we know that every action has an equal and opposite reaction, written in Newton's Law,
Thus, the wall will also exert a force of 100 N on the foot of the student.

Last month the ending balance on Maryanne’s Mastercard was $1,789, the average daily balance was $755, and the monthly periodic rate is 1.85%. Her finance charge can be calculated by multiplying the ending balance times the monthly periodic rate. So the finance charge is $1,789 ´ 0.0185 = $33.10.
Answer:
False
Step-by-step explanation:
Based on the information given we can calculate the finance charge of Maryanne’s by simply multiplying her average daily balance which is the amount of $755 times her monthly periodic rate which is 0.0185.
Hence, Maryanne's finance charge is calculated by using this formula
Finance charge=Average daily balance*Monthly periodic rate
Let plug in the formula
Finance charge= $755* 0.0185
Finance charge= $13.97
Therefore Maryanne's finance charge will be $13.97

Answer:
W = -1
Step-by-step explanation:
3W - 8 + 3W = -4 + 5W - 5
combine like terms
6W - 8 = -9 + 5W
subtract 5w on both sides
W - 8 = -9
add 8 on both sides
W = -1

Which equation represents a line perpendicular to the line whose equation is
6y+5x=48 !!!!!!
Step-by-step explanation:
im putting it in y=mx+b form here
6y+5x=48
subtract 5x on both sides
6y=-5x+48
divide by 6 on both sides
y=(-5x/6)+8
so the slope is -5/6
perpendicular lines have opposite inverse slopes
so
m=6/5
now that you know the slope, hopefully you can find the answer with the same slope, since you didn't provide potential options
A line having the same slope and perpendicular to the line 6y + 5x = 48 is
5y -6x = 40.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
We also know that perpendicular lines have slopes that are negative reciprocals of each other.
Given, 6y + 5x = 48, this in slope-intercept form is,
6y = -5x + 48.
y = (-5/6)x + 8.
Now, the line perpendicular to it has a slope of (6/5) and assuming it has the same y-intercept.
∴ The equation of the perpendicular line is y = (6/5)x = 8.
y - (6/5)x = 8.
5y -6x = 40.

On a coordinate plane, 2 triangles are shown. Triangle F D E is a right triangle and has points (1, 0), (1, 3), and (5, 0). Triangle Q R P is a right triangle and has points (negative 1, negative 2), (negative 1, negative 5), and (negative 5, negative 2). Are ΔDEF and ΔRPQ congruent? Yes. ΔDEF can be mapped to ΔRPQ by a reflection across the x-axis followed by a translation 2 units left. Yes. ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down. No. ΔDEF cannot be mapped to ΔRPQ by a rigid transformation or combination of rigid transformations.
Answer:
Yes
ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down
Step-by-step explanation:
The coordinates of the vertices of the triangles are;
F(1, 0), D(1, 3), and E(5, 0), and Q(-1, -2), R(-1, -5), and P(-5, -2),
Length of FD = √((3 - 0)² + (1 - 1)²) = 3
Length of DE = √((5 - 1)² + (0 - 3)²) = 5
Length of FE = √((5 - 1)² + (0 - 0)²) = 4
For triangle QRP, we have;
Length of QR = √((-5 - (-2))² + (-1 - (-1))²) = 3
Length of RP = √((-5 - (-1))² + (-2 - (-4))²) = 5
Length of PQ = √((-5 - (-1))² + (-2 - (-2))²) = 4
For a reflection across the x-axis, we have;
For a rotation of 180° about the origin, we have;
For a coordinate of the preimage before reflection of (x, y), the coordinates of the image after reflection is (-x, -y)
When followed by a translation 2 units down, we have the coordinates of the image will be (-x, -y-2)
Therefore;
For the points F(1, 0), D(1, 3), and E(5, 0) on triangle FDE, we have;
Rotation 180° about the origin gives;
F(1, 0) → Rotation by 180° → F'(-1, 0)
D(1, 3) → Rotation by 180° → D'(-1, -3)
E(5, 0) → Rotation by 180° → E'(-5, 0)
For a translation 2 unites of the coordinates of the vertices of the above triangle ΔF'D'E',
F'(-1, 0) → Translation 2 units down → F''(-1, -2)
D'(-1, -3) → Translation 2 units down → D''(-1, -5)
E'(-5, 0) → Translation 2 units down → E''(-5, -2)
The coordinates of the vertices of triangle ΔF''D''E'' are equivalent to the coordinates of the ΔQRP
Therefore, ΔDEF, and ΔRPQ are congruent, because ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down.
Answer:
Yes
ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down

find the area and perimeter
Answer: P=3 A=7 I think.
Step-by-step explanation:
The perimeter is basically how many sides are there so on this shape there is 3 if u count it and the area is how many squares or whatever is inside the shape so the 11 and 23 stand for the squares on those sides where the numbers are so if u add 11+23=34 so on the last side it only shows u 1 square and has no number so now u have to make the rest of those square till u cant and on the end of it it cant be a square bc its a triangle so it does not have a square like type of shape to where u can make it even.

A tree is currently 10 feet tall and grows 2 feet per year. Write an arithmetic sequence in explicit formula that can model this scenario.
Given:
A tree is currently 10 feet tall and grows 2 feet per year.
To find:
The arithmetic sequence in explicit formula that can model this scenario.
Solution:
Current height of tree is 10 feet. So, initial value of the arithmetic sequence is a=10.
It grows 2 feet per year. So, common difference is d=2.
The explicit formula for an arithmetic sequence is
[tex]f(n)=a+(n-1)d[/tex]
where, a is first term and d is common difference.
Put a=10 and d=2 in the above formula.
[tex]f(n)=10+(n-1)2[/tex]
[tex]f(n)=10+2n-2[/tex]
[tex]f(n)=8+2n[/tex]
Therefore, the explicit formula for given scenario is [tex]f(n)=8+2n[/tex].
