A scientist had 1.25 ounces of a chemical. He bought 2.5 ounces more of the chemical and then used 0.75 ounce in an experiment. How much chemical does the scientist have remaining?
Answer:
3 ouncesStep-by-step explanation:
Step one:
given data
the initial amount of chemical = 1.25 ounces
Extra amount of chemical =2.5 ounces
Total amount of chemical =1.25+2.5=3.75 ounces
Step two:
we are told that the scientist used 0.75 ounces of chemical
Hence the remaining chemical is
remaining= 3.75-0.75
remaining= 3 ounces
The remainder is 3 ounces
A phone company charges a base fee of $25 per month plus an additional charge per minute. The monthly phone cost can be represented by this equation: C=25+ a·m/4, where a is the additional charge per minute, and m is the number of minutes used. How can we re-write this equation to solve for the additional charge per minute?

what is the solution for 36.16=17.56+5x
Answer:
x=3.72
Step-by-step explanation:
Answer: x = 3.72
Step-by-step explanation:
36.16 = 17.56 + 5x
-17.56 = -17.56
18.6 = 5x
Divide 18.6 by 5 and divide 5 by 5.
3.72 = x

If a figure starts off in a Quadrant I and is reflected along the x-axis and then rotated 180 degrees about the origin, what quadrant will it land on?
Answer:
Quadrant 2
Step-by-step explanation:
First you reflect and it goes to Quadrant 4(Positive,Negative). When rotating 90 degrees you go to the next quadrant. In this case it is 180 degrees, so it ends up two quadrants away. The final location is quadrant 2
g/h-x=Q
solve for g
Answer:
g=(q+x)/(h)
Step-by-step explanation:
you would 1st add x to the q
g/h=q+x
then you would divide the h from both sides
g=(q+x)/(h)

Answer:
-1 or f = 1.333333333 + 0.3333333333x
is what i got its not an answer so im sorry
Step-by-step explanation:
Simplifying
f(6) = 2x + 8
Reorder the terms for easier multiplication:
6f = 2x + 8
Reorder the terms:
6f = 8 + 2x
Solving
6f = 8 + 2x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by '6'.
f = 1.333333333 + 0.3333333333x
Simplifying
f = 1.333333333 + 0.3333333333x

What is the equation of the line that passes through the points (4, 5) and (7, 3)
Answer:
y = -2/3x + 23/3
Step-by-step explanation:
Let equation of the line be y = mx + c
m = (3-5)/(7-4) = -2/3 gradient/slope formula
sub (4, 5)
5 = -2/3 (4) + c
c = 23/3
therefore, equation of the line is y = -2/3x + 23/3

between 2002 and 2008, more than 26 cubic miles of groundwater disappeared. how much water has disappeared per year
Explanation:
2008 - 2002 = 6 years have passed
In that time frame, we lost 26 cubic miles of ground water.
This means we lost about 26/6 = 4.333 cubic miles of ground water per year.
The University of Washington Huskies tried throwing one of the longest Hail Mary's in history
- about 73 yards. For this pass, the ball's height over time was modeled by the function
h(t) = –16t2 + 64t + 6, where h(t) was the height in feet and t was the time in seconds.
Let's break down whether the Huskies ever had a chance.
1.
73 yards isn't just a long way to throw, it's a long way to run. To give his team the
best chance of running all the way down the field and catching the ball before it hits
the ground, the quarterback (passer) needs to keep the football in the air for a long
time. How long was the ball in the air?
9514 1404 393
Answer:
4.09 seconds
Step-by-step explanation:
The ball is in the air until h(t) = 0. Solving that equation for t, we have ...
0 = -16t^2 +64t +6
t^2 -4t = 3/8 . . . . . . rearrange, divide by 16
t^2 -4t +4 = 4 3/8 . . . add 4 to complete the square
(t -2)^2 = 4.375 . . . . write as a square
t = 2 +√4.375 . . . . . positive square root, add 2
t ≈ 4.09165
The ball was in the air about 4.09 seconds.

Answer:
Cheetah's speed = 2.79 miles per hour
Step-by-step explanation:
Speed = Distance / Time
Distance = 335 miles, Time = 120 hours
So, speed = 335 / 120
Speed = 2.79 mph

Question 2 (1 point) Which ordered pair is a solution to the equation below? -4x + 2y = 16 O (-3, 2) O (4, -1) (2-3)
Answer:
A. (-3, 2)
Step-by-step explanation:
First step is to revert the equation into y = mx + b form.
-4x + 2y = 16 turns into y = 2x+8
Now just plug in the points given to see which one matches.
(-3,2) the x is -3 so if you plug that into the equation it should get you 2 which is the y.
2 = 2(-3) + 8
2 = 2
So we know that (-3, 2) is the solution.
If you plug in the other points they wont come out equal. For example, (4,-1)
-1 = 2(4) + 8
-1 = 16
So (4,-1) cant be a solution. The same thing applies for (2, -3).
The sum of four consecutive integers is -118. What is the largest of the integers?
Answer:
-28
Step-by-step explanation:
the four number are -28, -29, -30, and -31. they are all consecutive meaning all before or after the previous number. The sum is -118 making then all negative so when you add all the negative numbers you get and even bigger negative number. it is -28 because -28 is closest to 0.
Bob runs a total of 12 miles each week. He wants to increase the number of miles he runs each week by 1.5 miles until he is running a total of 26 miles each week. Provide an equation that can be used to determine the number of weeks Bob will need to reach his goal
Answer:
The equation is 12 + 1.5w = 26
Step-by-step explanation:
Each week running = 12 miles
He wants to increase the number of miles he runs each week by 1.5 miles until he is running a total of 26 miles each week.
12 + 1.5w = 26
Where,
w = number of weeks to reach his goal
12 + 1.5w = 26
1.5w = 26 - 12
1.5w = 14
Divide both sides by 1.5
w = 14 / 1.5
= 9.33 weeks

A relation contains the points (−2, 0), (−1, −1), (0, 2), (1, 0), and (1, −2). (show work if you can)
A. The relation does not represent y as a function of x, because each value of x is associated with a single value of y.
B. The relation represents y as a function of x, because one value of y is associated with two values of x.
C. The relation does not represent y as a function of x, because one value of x is associated with two values of y
D. The relation represents y as a function of x, because each value of x is associated with a single value of y.
Answer:
C. The relation does not represent y as a function of x, because one value of x is associated with two values of y
Step-by-step explanation:
I chose choice c because in the relation we can see that the x-value 1 repeated but their y-values are different, one has 0 as its y-value and one has -2 as its y-value. In a function, this can't happen so it's not a function.

The value of the variable x will be {0, pi/2, pi}. Then the correct option is B.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The trigonometric equation is given below.
tan (3π/4 - 2x) = - 1
We know that the value of tan 3π / 3 is negative one. Then the equation will be
tan (3π/4 - 2x) = tan 3π/4
Apply inverse of tangent on both sides, then the equation will be
(3π/4 - 2x) = 3π/4, -π / 4
- 2x = 0, -π
2x = 0, π
x = 0, π/2
Then the value of the variable x will be {0, pi/2, pi}.
Then the correct option is B.
The question was incomplete, but the complete question is given below.
