Liz types at a rate of 25 words per minute. The graph shows the number of words typed over time by 4 other students.
Which student types at the same unit rate of words per minute as Liz?
please help!
Answers
This is because if she types 25 words in one minute then that means she can type 50 words in 2 minutes (just multiply by 2). The only person on the graph who can type 50 words in 2 minutes is Britt.
Hope this helps! Any questions let me know :)
What information can be used to compare linear relationships? Explain why.
Answers
Answer:the slope and the y intercept (you can tell there linear if the slope is the same and the y-intercepts are different).
Step-by-step explanation:
Answer:
Sample Response: Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.
Step-by-step explanation:
Solve the system of equations.
y=4x
y = x^2 + 3

Step-by-step explanation
-2y - 3y + 8 = 8 -5y - 12
solve this equation fast please
Answers
What we need to do is cancel both like terms on both sides of this equation which is
8=8 and you remove them.
Then you are left with -2y-3y=-5y-12
What you need to do is add -2y-3y because they are like terms
Now you have -5y
Then you put -5y=-5y-12
So you have to now cancel equal terms on both sides of this equation which were “-5y=-5y”, then you turn them into a 0
Now you are left with 0=-12
Therefore the statement is false for any value of y.
A sports store is having a 20% off sale on skis. The original price of the ski is $560.00
The tax rate is 8.5%. What is the total cost of the skis?
Answers
Answer:
Total cost: 486.080$
Step-by-step explanation:
Original Price: 560.000$
Sale: 20%
Discount: 560.000$ * 20% = 112.000$
Discounted Price: 560.000$ - 112.000$ = 448.000$
Tax Rate: 8.5%
Tax: 448.000$ * 8.5% = 38.080$
Tax after Tax: 448.000$ + 38.080$ = 486.080$
Two years ago Juanita bought 2 shirts for $15 and last year she bought 4 shirts for $45. Assuming the prices will increase linearly, how much will 8 shirts cost Juanita this year?
Answers
Answer:
This year, Juanita will have to use $75.
Step-by-step explanation:
Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.
7. The lifetime of a certain brand of tires is approximately normally distributed, with a
mean of 40,000 miles and a standard deviation of 2,500 miles under normal driving conditions.
Tire wear is greatly affected by road, weather and driver conditions along with proper
maintenance of the tires. A driver who aggressively accelerates or makes quick stops, for
example, will wear out a tire much more quickly. The brand carries a warranty of 33,000 miles
under normal driving conditions, i.e., the company will replace a tire if it wears out before this
mileage limit is reached.
Answers
Answer:
0.0025551
Step-by-step explanation:
Given that:
Mean (m) = 40000
Standard deviation (s) = 2500
P(x < 33,000) :
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (33000 - 40000) / 2500 = - 2.8
p(Z < -2.8) = 0.0025551 ( Z probability calculator)
Probability of Tyre wagering out before mileage limit is reached = 0.0025551
Subtract the sum of −7 and 13 from the sum of −2 and −9 *
Answers
Answer:
-17
Step-by-step explanation:
The sum of -2 and -9 is (-2) + (-9) = -2 - 9 = -11.
The sum of -7 and 13 is 13 - 7 = 6.
Hence, subtracting 6 from -11 would be -11 - 6 = -17.

write an equation in slope intercept form for the line that passes through (1,-1) and is parallel to the line described by y=2x-4
PLEASE HELP:(((((
Answers
If 2 lines are parallel, their slopes are the same, so all we need to do is plug in the given point and slope in the equation y = mx + b and solve for b.
[tex]-1 = 2(1) + b\\\\-1 = 2 + b\\\\-3 = b[/tex]
The equation of a line in slope-intercept form that goes through (1, -1) and is parallel to the line y = 2x - 4 is [tex]y = 2x - 3[/tex].
(x+1)-6(x+1)+8 how to factorise it?
Answers
Answer:
Step-by-step explanation:
If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.
x + 1 + 6x + 6 + 8
7x + 15 is your final answer.
However, I think the question is
(x + 1)^2 + 6(x + 1) + 8
Let y = x + 1
y^2 + 6y + 8
(y + 2)(y + 4)
(x + 1 + 2 ) ( x + 1 + 4)
(x + 3)(x + 5)
A cork has a mass of 3 grams and a volume of 16 cm3

Answer:
0.1875, or 3/16
Step-by-step explanation:
The formula for density is mass/volume.
I hope this helps :)
Answer:
[tex]{\boxed {\sf \frac{3}{16} \ g/cm^3}}[/tex]
or
[tex]\boxed {\sf 0.1875 \ g/cm^3}}[/tex]
Step-by-step explanation:
Density can be found by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the cork is 3 grams and the volume is 16 cubic centimeters.
[tex]m= 3 \ g\\v= 16 \ cm^3[/tex]
Substitute the values into the formula.
[tex]\rho = \frac{3 \ g }{16 \ cm^3}[/tex]
Divide.
[tex]\rho=\frac {3}{16} \ g/cm^3[/tex]
[tex]\rho=0.1875 \ g/cm^3[/tex]
The density of the cork is 3/16 or 0.1875 grams per cubic centimeter.

solve the equation or inequality.
5t - 3 (7t + 1) < 93
Answers
Step-by-step explanation:
5t-3(7t+1) < 93
Remove the parentheses
5t-21t-3 < 93
-16t < 93+3
-16t < 96
Divide both sides by 16
-t<96/16
-t<6
t > -6
Answer: The inequality t < 6 is the correct answer.
Step-by-step explanation:
5t - 3 (7t + 1) < 93 <--- This is the original equation.
5t + (7t + 1) - 3 < 93 <---- Use commutative property.
16t - 3 < 93 <--- Simplify
16t - 3 + 3 < 93 + 3 <---- Add 3 to both sides,
16t < 96 <--- Simplify and do addition.
[tex]\frac{16t}{16}[/tex] < [tex]\frac{96}{16}[/tex] <--- Divide both sides by 16.
t < 6 <--- is the answer to the inequality.
