Answer:
9 - 1 = 8
Step-by-step explanation:
We can simplify the equation by changing 9 +(-1) to 9 - 1, therefore making it a subtraction problem.

medicine is given in an amount proportional to a patient's body weight. Suppose a patient weighing 119 pounds requires 136 milligrams of medicine.
What is the weight of a patient who requires 200 milligrams of medicine?
Answer:
weight of the patient = 175 pounds
Step-by-step explanation:
Patient body weight : medicine
119 : 136
What is the weight of a patient who requires 200 milligrams of medicine?
Let
Patient body weight = x
Patient body weight : medicine
x : 200
Equate both proportions
119 : 136 = x : 200
119 / 136 = x / 200
Cross product
119 * 200 = 136 * x
23,800 = 136x
x = 23,800 / 136
= 175
x = 175 pounds

xoxo, your highness...The teacher baked a batch of muffins there's are 16 muffin in a batch she ate 1/4 of the batch she baked two more batches how many muffins does she have now
Answer:
Step-by-step explanation:
she ate 1/4 of the batch = 16/4 = 4 muffins were left
she baked two more batches = 16* 2 = 32
4 + 32 = 36 muffins
or
no. of muffins in a batch: 16
no of muffins he ate = 1/4 of 16
= 4
no. of muffins left: 16 - 4= 12
his mother then baked 2 more batches= 16+16
=32
no. of muffins left = 32+12 = 44
dont forget to mark this as the branliest answer if it helped you!
#HAVE FUN!! with muffins!!!
#GautamPro
Answer:
44
Step-by-step explanation:
16-4 equals 12 each batch equals 16. 16 times 2 equals 32 plus 12 equals 44

What is the equation in point−slope form of the line passing through (1, 2) and (2, 5)? (5 points) Group of answer choices (y − 1) = −3(x − 2), (y + 2) = 3(x + 1,) (y − 2) = 3(x − 1), (y − 2) = −3(x − 1)
Answer using slope formula:
[tex]\frac{y2-y1}{x2-x1}[/tex]
We can find the slope.
Substitute:
[tex]\frac{5-2}{2-1}[/tex]
Subtract:
[tex]\frac{3}{1}[/tex]
[tex]\frac{3}{1}= 3[/tex]
Our slope is 3.
Now we will use Point Slope formula:
[tex]y-y1=m(x-x1)[/tex]
To find our equation.
I will use the first ordered pair, (1,2).
Substitute:
[tex]y-2=3(x-1)[/tex]
Your answer is C. (y − 2) = 3(x − 1).
Hope this helped! :)

A landscaping service company charges customers a one-time fee and an hourly rate of $15. For 1 hour of service, the company charges $45. Write an equation to represent the total charge C for h hours of landscaping.
Answer:
C = $30 + $15h
Step-by-step explanation:
Given that:
Hourly rate = $15
One time fee = x
Amount charged for an hour of service = $45
Hence,
One time fee + $15* 1 = $45
One time fee = $45 - $15
One time fee = $30
Hence, total charge C for h hours of landscaping:
Total charge = one time fee + (hourly charge * number of hours)
C = $30 + $15h

can somebody teach me how to do this 1 math question, its about solve for the area! WILL Give Brainiest!
Answer:
area is 100m bc u do 10 times 10
Step-by-step explanation:
Answer:
139.27 meters squared
Step-by-step explanation:
So what you're doing is calculating the square's area and half of the circle's area.
The square's area is 100m^2 since 10*10=100
For the circle part, you use πr^2. You know the diameter of the circle, and radius is half of the diameter, so 10/2=5.
π*5^2 = 78.54 m^2
Since you have half of a circle you divide this by 2.
39.27
Finally you add your two areas together
100+39.27=139.27 meters ^2
Solve the following:
a) -5/4 [8/7+16/5]
Answer:
-38/7
Step-by-step explanation:
We are given [tex]-\frac{5}{4}(\frac{8}{7}+\frac{16}{5})\\[/tex]. First find the sum of the fractions in the parentheses. The greatest common multiple is 35 so we have [tex]\frac{8}{7}+\frac{16}{5}=\frac{40}{35}+\frac{112}{35}[/tex].
The sum of [tex]\frac{40}{35}+\frac{112}{35}[/tex] is [tex]\frac{152}{35}[/tex].
Now we multiply it by [tex]-\frac{5}{4}[/tex] so we have
[tex]\\-\frac{5}{4} \cdot \frac{112}{35}\\=-\frac{1}{7}\cdot \frac{38}{1}\\=\boxed{-\frac{38}{7}}\\[/tex]
Jeff can walk 3 laps in 8 minutes. At this pace, how many full laps can he walk in 20 minutes?
Answer:
7 full laps
Step-by-step explanation:
let x= how many laps
[tex]\frac{3}{8} =\frac{x}{20}[/tex]
cross multiply
60=8x
60/8=x
7.5=x
7 full laps (because 0.5 is half a lap)
Answer:
7 full laps
let x= how many laps
cross multiply
60=8x
60/8=x
7.5=x
7 full laps (because 0.5 is half a lap)

Two sailboats are traveling along the same path away from a dock, beginning from different locations at the same time. John’s boat beings 30 miles from the dock and is 50 miles from the dock after 5 hours. The distance of Roberta’s boat from the dock is represented by the function y = 5x + 25, where x represents time and y represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled more quickly?
A. John’s boat was farther from the dock at the beginning, but Roberta’s boat traveled more quickly.
B. Roberta’s boat was farther from the dock at the beginning, and it traveled more quickly.
C. John’s boat was farther from the dock at the beginning, and it traveled more quickly.
D. Roberta’s boat was farther from the dock at the beginning, but John’s boat traveled more quickly.
Please Help!!!!
Answer:
c
Step-by-step explanation:
The correct statement is John’s boat was farther from the dock at the beginning, and it traveled more quickly option (C) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two sailboats are traveling along the same path away from a dock, beginning from different locations at the same time.
y = 5x+25
at starting x=0
y = 25 miles away from the dock
x = 5
y = 5×5+25
y = 50 miles
= (50 - 25)/5
= 5
Thus, the correct statement is John’s boat was farther from the dock at the beginning, and it traveled more quickly option (C) is correct.

You are running an experiment in class where you draw colored marbles out of a bag. There are
eight marbles in the bag, you will draw five times, and you will replace the marble each time. How many ways can you draw the marbles out of the bag?
A: 40
B: 3,360
C: 4,096
D: 32,768
Answer:
32768 ways
Step-by-step explanation:
Given
Marbles = 8 marbles
Selection = 5 (with replacement)
Required
Determine the number of ways
Because it is a selection with replacement; each selection is as follows:
[tex]First = 8\ marbles[/tex]
[tex]Second = 8\ marbles[/tex]
[tex]Third= 8\ marbles[/tex]
[tex]Fourth = 8\ marbles[/tex]
[tex]Fifth = 8\ marbles[/tex]
Total number of ways is then calculated as:
[tex]Total = 8 * 8 * 8 * 8 * 8[/tex]
[tex]Total = 32768[/tex]
pls :,) i suck at math
Answer:
60%
Step-by-step explanation:
The original was $20 to $12, so if you divide both prices by 2 (to make one side 10 and the other the simplified percentage) you get:
10 to 6.
Percentages are typically x% out of 100, so if you multiply both by 10 you get:
100 to 60. All you have to do now is change the format to percentage instead of a fraction (60/100) and the answer is 60%.
