Answer:
8 and 9
Step-by-step explanation:
Since 77 is between 64= 8² and 81= 9²
√64 < √77 < √818 < √77 < 9Diego and Max are buying soft drinks for a neighborhood picnic. Each person is expected to drink one can of soda. Diego says that if you multiply the unit price for a can of soda by the number of people attending the picnic, you will be able to determine the total cost of the soda. Max says that if you divide the cost of a 12-pack of soda by the number of sodas, you will determine the total cost of the sodas.
Which choices best illustrates who is correct and why?
Max is incorrect because he calculated the cost of one can of soda
Diego is incorrect because he calculated the price of one can of soda
Max is correct because the total cost divided by the number of sodas gives you the total cost of the sodas
Diego is correct because the price of one can of soda multiplied by the number of sodas needed will give you the total cost of the soda.
Answer:
D). Diego is correct because the price of one can of soda multiplied by the number of sodas needed will give you the total cost of the soda.
Step-by-step explanation:
Since every person is expected to drink one can of soda:
Let the price of each can of soda = p
and the total number of people present at the picnic = n
∵ Total price = p(the price of each soda can) * n(number of people)
Thus, Diego correctly asserts that if he multiplies the 'unit price for a can of soda by the number of people attending the picnic', he would be able to deduce the total cost of soda. Hence, Max is incorrect and option D is the correct answer.

find the length of a line segment whose endpoints are (-2,3) and (6,3)
Answer:
8
Step-by-step explanation:
Since we want to find the length of a line segment, we can use the distance formula.
[tex]d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1} )^2 }[/tex]
(x₁, y₁) and (x₂, y₂) are the points given.
The points we are given are: (-2,3) and (6,3). Therefore,
[tex]\\x_{1} =-2\\y_{1}=3 \\x_{2} = 6\\y_{2} =3[/tex]
Plug each value into the formula.
[tex]d=\sqrt{{(6--2})^2+(3-3 )^2} }[/tex]
Evaluate inside of the parentheses first.
[tex]d=\sqrt{(6+2)^2+(0)^2}[/tex]
[tex]d= \sqrt{(8)^2+(0)^2 }[/tex]
Evaluate the exponents.
8²= 8*8=64
[tex]d=\sqrt{64+(0)^2}[/tex]
0²= 0*0= 0
[tex]d=\sqrt{64+0}[/tex]
Add 64 and 0.
[tex]d=\sqrt{64}[/tex]
Take the square root of 64.
[tex]d= 8[/tex]
The length of the line segment is 8
20 POINTS ! An international company has 17,800 employees in one country. If this represents 22.1% of the company's employees, how many employees does it have in total? Round your answer to the nearest whole number. Thankyou!
Answer:
80,543 employees total
Step-by-step explanation:
22.1% of total = 17,800 employees
0.221 of x = 17800
0.221 • x = 17800
x = 17800 / 0.221
x = 80542.98643
x ≈ 80543 employees total
According to the bar graph, how many more pages did the winner of the contest read than the loser? Show your work or explain how you got your answer.
Well look at the question.
It is asking you the total difference between the winners score to their opponents score in the contest.
Going by how the graph looks, approximately:
Javi's scores are 10, 20, 60, 20, and 15.
MeriAnne's scores are approximately 20, 30, 40, 20, and 10.
Add all those numbers up individually for each contestant.
Javi has a total score of 125.
Meri has a total score of 120.
Subtract the total scores from each other, as so:
125 - 120 = 5.
Javi read 5 more pages than Meri.

Jason watched a caterpillar move 16 feet in 8 minutes. Jason says that the caterpillar's unit rate is 0.5 foot per minute. Is Jason correct? Drag and drop numbers and words into the correct boxes to complete the explanation.
Answer:
Jason is incorrect.
The caterpillar's rate is 2 ft/min
Step-by-step explanation:
The rate of motion is defined as the quotient between the distance covered (in our case 16 feet) divided by the time it took to cover that distance (in our case 8 minutes)
Then, the rate is:
[tex]rate=\frac{distance}{time} = \frac{16\,\,ft}{8\,\,min} = 2\,\frac{ft}{min}[/tex]
a) What is a tessellation? Give two everyday examples of tessellations (that do not extend
indefinitely). You may insert images or give a verbal description. (5 points)
please help
The tile in a bathroom or kitchen is one example of tessellation. It's where you place geometric shapes together to fill a space. In this case, we have squares placed together to fill the space of the wall or floor. There cannot be any gaps or overlaps.
Another example would be bricks as this is composed of rectangles placed together without any gaps or overlaps. There are many other examples as well usually done as floor or wall patterns of some kind. Some tessellations involve using more than one shape (eg: one pattern uses squares and equilateral triangles placed together).

if 3 divide a profit of rs 72,000 at end of the year according to the ratio of 2:3:4 of their investment how much did they receive
Step-by-step explanation:
Hey, there!!
See explanation in picture.
They receive 16000, 24000 and 32000 as per the ratios 2:3:4.
let x be a common factor,
Then,
2x+3x+4x =72000
sum them,
9x= 72000
x = 72000/9
=8000
Therefore, x= Rs. 8000.
2x= 8000×2 = Rs.16000
3x= 3×8000= Rs.24000
4x= 4×8000= Rs. 32000
You just need to put common factor on the ratios and then sum up them to get the value.
Hope it helps..

In a certain Algebra 2 class of 21 students, 11 of them play basketball and 6 of them play baseball. There are 6 students who play neither sport. What is the probability that a student chosen randomly from the class plays both basketball and baseball?
Answer:
Step-by-step explanation:
total number of students=21
students play neither sport=6
students who play at least one sport=21-6=15
Let play basketball=X

Parallel lines are coplanar. What characteristics of these geometric figures create the different requirements?
Answer:
Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.

find the perimeter of an isosceles triangle with side lengths of 5+x, 5+x, and xy. Write in simplest form.
To get the perimeter, you add up all the outer sides
side1+side2+side3 = (5+x)+(5+x)+(xy) = 10+2x+xy
The like terms 5 and 5 add to 10. The other pair of like terms x and x add to 2x. There isn't anything to pair with xy, so we leave it as is.

What is the domain of the function shown in the
mapping?
O x x= -5,-3,1,2,6}
O fyy=-9,-6,0, 2, 4)
O(|x=-9,-6.-5.-3, 0, 1, 2, 4, 6)
O fyly = -9,-6, -5,-3,0,1.2, 4, 6)
Answer:
{x | x = -5, -3, 1, 2, 6}
Step-by-step explanation:
In a function, the domain values are all the possible values of input in a function. In order words, they are the x-values in a function, which are also referred to as independent variable.
In the mapping of the function above, all input values make up the domain of the function.
Thus, the domain is:
{x | x = -5, -3, 1, 2, 6}

If 3x+2=7(3-x), find the value of 26-x-4
Answer:
20.1
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, distribute 7 to all terms within the parenthesis:
7(3 - x) = (7 * 3) + (7 * -x) = 21 + -7x = 21 - 7x
3x + 2 = 21 - 7x
Isolate the variable, x. Subtract 2 and add 7x to both sides:
3x (+7x) + 2 (-2) = 21 (-2) - 7x (+7x)
3x + 7x = 21 - 2
10x = 19
Divide 10 from both sides:
(10x)/10 = (19)/10
x = 19/10 = 1.9
Plug in 1.9 for x in the expression given:
26 - x - 4 = 26 - 1.9 - 4
26 - 1.9 = 24.1
24.1 - 4 = 20.1
20.1 is your value.

Momo has $4.05 in dimes and quarters. If she has 5 more quarters than dimes,
how many of each does she have? Show your work and write a complete
sentence answer
Answers:
8 dimes13 quarters==================================================
Work Shown:
$4.05 = 405 cents
d = number of dimes
q = number of quarters
q = d+5 since she has 5 more quarters compared to dimes
10d = value in cents of all the dimes
25q = value in cents of all the quarters
10d+25q = total value in cents = 405
10d+25q = 405
10d+25(d+5) = 405
10d+25d+125 = 405
35d+125 = 405
35d = 405-125
35d = 280
d = 280/35
d = 8
She has 8 dimes
q = d+5 = 8+5 = 13
She also has 13 quarters
-------------------------
1 dime = 10 cents
8 dimes = 80 cents (multiply both sides by 80)
1 quarter = 25 cents
13 quarters = 325 cents (multiply both sides by 13)
8 dimes + 13 quarters = 80 cents + 325 cents = 405 cents
This converts back to $4.05, which confirms our answers.
