Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden. What is his unit rate
Answer:
20 minutes per row
Step-by-step explanation:
Divide the total time by the total number of rows to find the amount of time for one row
6r= 120
Divide each side by 6 to isolate the variable (r= number of rows)
r= 20
Water can exist in three states:
solid Ice, liquid water, and
gaseous water vapor. It takes a
certain amount of heat before
water can change state. Use the
following information to sketch the
graph of the function representing
the temperature of water as a
function of the amount of total
heat added in Joules (1). Explain
why this situation involves
piecewise function.
Answer:
The graph illustrates the process of changing ice at –50°C to steam at 150°C.
Most thermal conductors are made of which material?
plastic
glass
rubber
metal
Most thermal conductors are made up of metal material.
We have to determine, most thermal conductors are made of which material?
According to the question,
It is one of the three concepts by which heat and energy can be transferred from one place to the other within a material or from one material to another.
Conduction occurs by direct contact whereas Convection occurs by movement or flow of heat.
Radiation on the other hand occurs with the help of electromagnetic waves.
Conduction mostly occurs in metals and the conductivity of metal is different from one another.
When it comes to the best metal for thermal conductivity, ideally it is Silver but Copper is used instead.
The reason for it is that Silver is too expensive and is infeasible to use. Copper, on the other hand, is available in abundance, is affordable, and can be used in any application.
Hence, Most thermal conductors are made up of metal material.

My question is, on Sunday, 77,098 fans attended a New York Jets game. The same day, 3,397 more fans attended a New York Giants game than attended the Jets game. Altogether, how many fans attended the games? Round each number to the nearest thousand to find an estimate of how many fans attended the games.
Answer:
Total number of fan = 80,495
Step-by-step explanation:
Given:
Number of fans attended = 77,098
Additional number of fans attended = 3,397
Find:
Total number of fan
Computation:
Total number of fan = Number of fans attended + Additional number of fans attended
Total number of fan = 77,098 + 3,397
Total number of fan = 80,495
identify the slope of the line for the equation 1/6 x + 1/4
Answer:
y = 1/6x - 8/3
Step-by-step explanation:
The equation of a line in slope-intercept form is.
y = mx + b
where m represents the slope and b, the y-intercept.
Rearrange y + 2 = 1/6 (x - 4) into this form
distribute bracket and simplify.
y + 2 = 1/6x - 2/3
⇒ y = 1/6x - 2/3 - 2
⇒ y = 1/6x - 8/3 ← in slope-intercept form

Manny and Zack are hosting events that are catered by the same company. Manny plans to have 66 adults and 27 children attend, so the total projected cost of his meals is $3,651. Zack has 77 adults and 43 children on his guest list, so he will pay the caterer $4,409. How much does the caterer charge for each meal?
Answer:
The caterer charged $50 for an adult's meal and $13 for a child's meal
Step-by-step explanation:
Let the cost of an adult meal be $x
and the cost of a child meal be $y
From the question,
Manny plans to have 66 adults and 27 children and the total cost of his meals is $3,651.
We can write that
66x + 27y = 3651 ...... (1)
Also, from the question,
Zack has 77 adults and 43 children and the total cost he will pay the caterer is $4,409.
We can also write that
77x + 43y = 4409 ...... (2)
Multiply equation (1) by 7, so that we get
462x + 189y = 25557 ...... (3)
Multiply equation (2) by 6, so that
462x + 258y = 26454 ...... (4)
Now, subtract equation (3) from equation (4), so that
69y = 897
∴ y = 897/69
y = 13
Put the value of y into equation (1) to get x
66x + 27y = 3651
∴ 66x + 27(13) = 3651
66x + 351 = 3651
66x = 3651 - 351
66x = 3300
x = 3300/66
x = 50
Therefore,
The cost of an adult's meal is $50
and the cost of a child's meal is $13
Hence, the caterer charged $50 for an adult's meal and $13 for a child's meal.

-66 = -9n + 16n + 4
Solve these step by step pls
Answer:
n= -10
Step-by-step explanation:
-66=7n+4
-7n=4+66
-7n=70
n=70/-7
n= -10
Answer:
n = -10
Step-by-step explanation:
-66 = -9n + 16n + 4
1. I started by subtracting 4 on both sides of the equation this gives you -70 = -9n + 16n
2. I then combined the like terms 16n and -9n on the right side of the equation. We do this by subtracting 9n from 16n. Which gives you -70 = 7n
3. We then divide both sides by 7 in order to get -10 = n
This gives you your final answer of n = -10

Step-by-step explanation:
If you are adding 15 less to 3 of n, it would be 3n-15 because 3 of n is 3n. After, you add n as well, so you get 3n-15+n. Your result is 101 so it should be on the other side of the equation.

Find the intersection point for the following linear functions.
f(x) = 2x + 3
g(x) = -4x − 27
A. (5,-7)
B. (5,13)
C. (-5,-10)
D. (-5,-7)
Answer:
D) (-5, - 7)
Step-by-step explanation:
Because both lines intersect, they must share a point (have same x and y coordinates).
[tex]2x + 3 = - 4x - 27[/tex]
[tex]2x = - 4x - 30[/tex]
[tex]6x = - 30[/tex]
[tex]x = - 5[/tex]
Substite x for - 5 in any of the equations to find the y coordinate.
[tex]y = 2( - 5) + 3 [/tex]
[tex]y = - 10 + 3[/tex]
[tex]y = - 7[/tex]
The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)

plus $19.99 per hour
let x be the number of hour
and y be the total charge of the magician.

If you subtract 13 from my number and multiply the difference by -2 , the result is -44." What is 's number
Answer:
n = 35
Step-by-step explanation:
n - 13 x -2 = -44
distribute:
(n x -2) - (13 x -2) = -44
-2n - (-26) = -44
two negatives in front of a number makes it a positive number
so rewrite -2n + 26 = -44
-2n = -44 -26
-2n = -70
n = [tex]\frac{-70}{-2}[/tex]
n = 35
calc check (35 - 13) x -2 = 22 x (-2) = -44
Find the exact rotation in revolutions per minute with the angular speed below:
Answer:
The exact rotation in revolutions per minute is 1.125 revolutions per minute
[tex]\omega = 1.125 \ \dfrac{Revolution}{minute}[/tex]
Step-by-step explanation:
The given angular velocity is expressed as follows;
[tex]\omega = 135 \cdot \pi \ \dfrac{rad}{h}[/tex]
Therefore, we have;
[tex]\omega = \dfrac{135 }{60} \cdot \pi \ \dfrac{rad}{minute} = \dfrac{9}{4} \cdot \pi \ \dfrac{rad}{minute} = 2.25 \cdot \pi \ \dfrac{rad}{minute}[/tex]
One (1) revolution = 2·π radian
Therefore;
π radian = 1/2 revolution
2.25·π radian = 2.25 × 1/2 revolution = 1.125 revolution
Which gives;
[tex]2.25 \cdot \pi \cdot \dfrac{rad}{minute} = 1.125 \ \dfrac{Revolution}{minute}[/tex]
The exact rotations in revolutions per minute is 1.125 revolutions per minute.
if 1/2 gallon of paint covers 1/12 of a wall,then how many quarts of paint are needed for the entire wall
Answer: 4
Step-by-step explanation: there is 4 quarts in a gallon so 1/2 gallon is 2 quarts. 2x2=4
Answer:
6 gallons which is 24 quarts
Step-by-step explanation:
because while covering 2/12ths of a wall you used a whole gallon of paint so if 1 gallon covers 2/12ths of a wall you have 10/12ths left and s you already used 1 so it would leave you with 5 gallons and 10 divided by 2 is 5 which would give you your answer 6 gallons and there are 4 quarts in a gallon so you would multiply 6 *4 = 24
Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?
Step-by-step explanation:
A. For Tavon's gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=145-3.5x------1
for Tavon's second gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=125-3x-------------2
B. equating 1 and 2 we have
145-3.5x=125-3x
solve for x we have
145-125=-3x+3.5x
20=0.5x
divide both sides by x we have
x=20/0.5
x= 40
put x=40 in
y=145-3.5*40------1
y=145-140
y=$5
put x=40 in
y=125-3*40------1
y=125-120
y=$5
What is the measure of each angle of the hexagon? 60° 90° 120° 144°
Answer:
120
Step-by-step explanation:
A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.
