The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

To the nearest tenth of a square centimeter, what is the
surface area of the cone if the radius of its base is 5 cm and
its height is 12?
Work Shown:
SA = surface area of cone
SA = pi*r^2 + pi*r*sqrt(r^2 + h^2)
SA = pi*5^2 + pi*5*sqrt(5^2 + h^2) ... plug in r = 5
SA = pi*5^2 + pi*5*sqrt(5^2 + 12^2) ... plug in h = 12
SA = pi*25 + pi*5*sqrt(169)
SA = 25pi + 5pi*13
SA = 25pi + 65pi
SA = 90pi .... exact surface area in terms of pi
SA = 282.743338823081 .... see note below
SA = 282.7
note: this is the approximate surface area. I used the calculator's stored value of pi, rather than something like pi = 3.14; that way the surface area is as accurate as possible. Your teacher may want you to use pi = 3.14 though, which is why its a good idea to ask and clarify.
Which graph is defined by f(x)=x^2+5|x|+6
Answer: C
Step-by-step explanation:
You are given a graph which is defined by f(x)=x^2+5|x|+6
Where the intercept of the graph is 6
Since the equation of the graph has a modulus 5|x|. Which can be span to the negative x component and positive x component, the root of the quadratic function will both be at negative x component and positive x component.
Which are 2 and 3 or -2 and -3
Option C is therefore the best graph for the answer to the question.
A bag contained 18 red marbles, 14 green marbles, and 20 blue marbles. A marble was randomly pulled, the color recorded, and then put back into the bag. This table above shows the results after 25 pulls.
What was the relative frequency of selecting a red or blue marble?
Red:8
Blue8
Green9
Number of red marbles pulled = 8
Number of blue marbles pulled = 8
Total marbles pulled = 25
Relative Frequency = Total Frequency / Total number of data values
Relative Frequency of red marble = 8/25
= 32%
Relative Frequency of blue marble = 8/25
= 32%

The box plots show the weights, in pounds, of the dogs in two different animal shelters.
Weights of Dogs in Shelter A
2 box plots. The number line goes from 6 to 30. For the weights of dogs in shelter A, the whiskers range from 8 to 30, and the box ranges from 17 to 28. A line divides the box at 21. For shelter B, the whiskers range from 10 to 28, and the box ranges from 16 to 20. A line divides the box at 18.
Weights of Dogs in Shelter B
Which describes the spread of the data in the two box plots?
The data in shelter A show more spread than the data in shelter B.
The data in shelter B show more spread than the data in shelter A.
The data in shelter A range from about 17 to 28, while the data in shelter B range from about 16 to 20.
The data in shelter A range from about 21 to 28, while the data in shelter B range from about 18 to 20.

→ Find the required value of x.
Let's find the value of x,
→ 21/35 = 18/x

It will take them 8,100 minutes.
It will take them 8,745 minutes.
Answer:
It will take them 8,100 minutes.
Step-by-step explanation:
If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)
150 x 54 minutes = 8,100 minutes.

Hello! :)
Answer:
\(\huge\boxed{751}\)
Let the smallest digit, or the units' digit, be equal to x:
Tens' digit is four more, therefore:
x + 4 represents the tens' digit.
Hundreds' digit is 2 more than the tens' digit, so:
2 + (x + 4), or x + 6 represents the hundred's digit.
These all sum up to 13, so write an expression to represent this:
x + (x + 4) + (x + 6) = 13
Combine like terms:
3x + 10 = 13
Subtract 10 from both sides:
3x = 3
Divide both sides by 3:
x = 1
Find the digits using the rules listed above:
Hundreds' digit: (1) + 6 = 7
Tenths' digit: (1) + 4 = 5
Units' digit: 1 = 1
Therefore, the number is:
751.

Garden Salad = x+3.25
Bowl of Chili = 2x <----- That the Table ;-;
Chicken Wrap = 3x-2
Part A: Write an expression to represent the cost of two garden salads and three chicken wraps.
Part B: Simplify your expression from Part A
Part C: If the Value of X is 3.25, how much more does a chicken wrap cost than a bowl of chili.
Answer: part A.) 2(x+3.25)+3(3x-2) for two salads and three chicken wraps
Part B.) 11x - .50
Part C.) A chicken wrap costs $1.25 more than a bowl of chili.
Step-by-step explanation:
A. Multiply the number of orders by the item cost expressions then add: 2(x+3.25) garden salads
+ 3(3x-2) chicken wraps
B.) Simplify: 2(x+3.25) + 3(3x-2)
2x + 6.50 + 9x - 6 combine like terms 2x+ 9x +6.50-6
11x + .50
C.) Substitute 3.25 for x to compare costs:
2(3.25) bowl of chili = 6.50
3(3.25 )-2 = 9.75 -2
chicken wrap = 7.75
Difference 7.75-6.50 = 1.25
Chicken wrap costs $1.25 more.

P to Q: greater than 1P to R: greater than 1Q to S: less than 1Q to R: greater than 1S to P: equal to 1R to P: less than 1P to S: equal to 1========================================================
Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.
