Explanation:
Lana's little sister needs to take a bubble bath. The package says to put in a drop of bubble bath for every half gallon of water in the bath tub. Lana doesn't know how many half gallons there are, but she knows that their bathtub can hold 12 gallons of water. How many drops can she put into the bath for her sister?
Answer:
Lana can put 24 drops of bubble bath for her sister
Step-by-step explanation:
If package says to put in a drop of bubble bath for every half gallon of water in the bath tub.
If the bathtub can hold 12 gallons of water
There are 12÷1/2 gallon

Answer:
y = 2/3x + 2/3
Step-by-step explanation:
just substitute every known value into the parent function on a linear function
y = mx +b
-4 = 2/3(-7) +b
now solve for b (the y-intercept)
-4 = -14/3 + b
-12/3 = -14/3 + b ( made it to same denominator)
2/3 = b

You start a chain email and send it to 3 friends. The process continues and each of your friends forward the email to 3 other people. What is an expression for the nth term an?
Answer:
[tex]a_{n}=3^{n}[/tex]
Step-by-step explanation:
We can start solving this problem by making a list of the number of chain emails that are sent on each round:
Round one:
[tex]a_{1}=3[/tex]
which represents the three friends you send the mail to.
Round two:
[tex]a_{2}=3*3=9[/tex]
since each of your friends sends the mail to another three friends, then we multiply the original 3 friends by 3 to get a total of 9.
Round three:
[tex]a_{3}=3*3*3=9*3=27[/tex]
on the next round we multiply the previous 9 persons by 3 mails each giving us a total of 27 persons receiving the mail. A patter starts showing here. Notice that for each round we need to take the previous round number an multiply it by 3. When we have a number being multiplied by itself n times, we rewrite it as a power, so the expression for the nth term will be:
[tex]a_{n}=3^{n}[/tex]
which is our final answer.
A right triangle is shown below.
Which measurement is the closest to the value of x?
Answer:
35°
Step-by-step explanation:
First you find the sine of x. That would be
sinx = opposite/hypotenuse
sinx = 57/100
sinx = 0.57
You can look it up if you want, but sin35 = 0.574
so the answer is 35°
The closest to the value of x is 35°.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
In order to find the sine of x. That would be
sinx = opposite/hypotenuse
sinx = 57/100
sinx = 0.57
sin35 = 0.574
Hence, the answer is 35°.

Answer:
The complete question is as below:
Stacy and Melissa work as waitresses. They both earn $7.75 per hour, plus tips. Last weekend, Stacy worked x number of hours and earned $153.95 in tips. Melissa worked y number of hours and earned $129.02 in tips. Stacy determined that using the expression 7.75x + 153.95 + 7.75y + 129.02 will calculate the amount the girls earned together last weekend. Select another expression the girls could also use.
A. 7.75x + y + 282.97
B. 7.75(x + y) + 282.97
C. 7.75(xy) + 282.97
D. 7.75x + 7.75y – 282.97
Option B,7.75(x + y) + 282.97 is correct
Step-by-step explanation:
Stacy already calculated total earnings of both of them with expression
7.75x + 153.95 + 7.75y + 129.02
The expression can be rewritten by simplifying it
first and foremost we can arrange the expression as follows:
7.75x+7.75y+153.95+129.02
7.75 is common to 7.75x+7.75y
7.75(x+y)+153.95+129.02
the sum of these two numbers 153.95+129.02=282.97
7.75(x+y)+282.97
From all indications,option B is the correct answer out of all options provided
Option D is obviously because of the negative sign introduced since the requirement is to compute total earnings not the difference between the two earnings

the sum of two integers is 81.if the product is 1088.what are the integers
Answer:
(a;b)={(17; 64); (64; 17)}
Step-by-step explanation:
a+b=81 => b=81-a
a*b=1088
a*(81-a)=1088
-a²+81a=1088
a²-81a+1088=0
a²-64a-17a+1088=0
a(a-64)-17(a-64)=0
(a-17)(a-64)=0
=> a=17 and a=64
for a=17 => b=81-17=64
for a=64 => b=81-64=17
(a;b)={(17; 64); (64; 17)}
The two integers are equal to a = 17 and b = 64.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The two integers are,
a+b=81 => b=81-a
a x b=1088
Calculate the value of one integer,
a x (81-a)=1088
-a²+81a=1088
a²-81a+1088=0
a²-64a-17a+1088=0
a(a-64)-17(a-64)=0
(a-17)(a-64)=0
Calculate the value of the second integer b,
=> a=17 and a=64
for a=17 => b=81-17=64
Therefore, the two integers are equal to a = 17 and b = 64.

Mr. Stewart used a gallon of vinegar to make 15 different color egg dipping containers. He used the same amount of vinegar in each container. How much vinegar in gallons was used in each egg dye container?
Answer:
0.067 gallons ( to 2 decimal places)
Step-by-step explanation:
First, note that since the same amount of vinegar was used in each container, it means that the 1 gallon of vinegar was divided equally to the 15 containers, hence the amount of vinegar used in each dye container is calculated as follows:
total volume of vinegar = 1
number of egg dye containers = 15
if equal volume of vinegar was used in each container:
volume of vinegar in each egg dye container = 1 ÷ 15 = 0.067 gallons ( to 2 decimal places)

True or false: the height is always twice the length of the base edge for any triangular pyramid
Answer:
FALSE
Step-by-step explanation:
The length of the base edge of a triangular pyramid may vary.
The height is not always twice the length of the base edge for any triangular pyramid, the dimensions are not fixed for any shape and can vary from one design to another.
more so, i may require a particular size or dimension of triangular based pyramid for my application that may not suit your application.

Heyo, I don't get where she got the 49 from, can someone help?
Answer:Instructions below
Step-by-step explanation:
This is completing the square, so what happened was that -14 was divided, then squared, to find a perfect square. To find the third term, you have to divide it by two then square it, then add it to the other side to balance the equation out.
-14/2 = -7^2 = 49 This applies to every question in which you have to complete the square
2x + 8y = 21 6x - 4y = 14
Step-by-step explanation:
{2x+8y=14
{216x-4y=14
{x+4y=7
{216x-4y=14
217x=21
x=3/31
2*3/31+8y=14
y=107/62
(x,y)=(3/31, 107/62)
2*3/31+8*107/62=216*3/31-4*107/62=14
14=14=14 since all of the equalities are true the order pair is the solution of the system (x,y)=(3/31, 107/62)
hope this helps :)
The lines y=x+1 and y=-x-3 are graphed.
What is the solution to the system?
Please help
Answer: (-2, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the x and y that is the solution to this system of equations.
The two lines intersect in quadrant III
where x and y are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 2 and down 1 so that's (-2, -1).
So the solution to this system is (-2, -1).
what is the volume of this hemisphere? Exact answer in terms of π the radius is 48 m options 1) 9,216 π cubic meters 2) 18,432 π cubic meters 3) 28,938 π cubic meters 4) 57,876 π cubic meters
Answer:
Volume, [tex]V=73728\pi \ m^3[/tex]
Step-by-step explanation:
The formula for the volume of hemisphere is given by :
[tex]V=\dfrac{2}{3}\pi r^3[/tex]
r is radius of hemisphere, r = 48 m
[tex]V=\dfrac{2}{3}\pi\times (48)^3\\\\V=73728\pi \ m^3[/tex]
So, the volume of hemisphere is [tex]73728\pi \ m^3[/tex].
