Two numbers have a sum of 23 and a difference of 5. What is the smaller of the two numbers.
x + y = 23
x - y = 5
(23 - 5) : 2 = 9
9 + 5 = 14

Which expressions have a value that is between 9 and 10. Select all that apply.
A.) √80
B.) √89
C.) √101
D.) 3 √725
E.) 3 √750
F.) 3 √999
G.) 3 √1010
Considering that the square root of 9 is of 81 and of 10 is of 100, we have that the expression that has a value between 9 and 10 is given by:
B.) √89
E.) [tex]\sqrt[3]{750}[/tex]
F.) [tex]\sqrt[3]{999}[/tex]
How the square root of a number is used to solve this question?We suppose numbers n and m, with square roots given, respectively, by n² and m².
Then, the square roots of all numbers between n² and m² have values between n and m.
In this problem, the square roots are given by:
9² = 81.10² = 100.Hence, the square root of all values between 82 and 99 are values between 9 and 10, thus option B is correct.
As for the cubic root, we apply the same logic and have that:
9³ = 729.10³ = 1000.Hence options E and F are also correct, as the values between 730 and 999 have cubic roots between 9 and 10.

Grogg typed the following $1000$ expressions into his calculator, one by one: \[\sqrt{1}, \sqrt{2}, \sqrt{3}, \sqrt{4}, \dots, \sqrt{999}, \sqrt{1000}. \]how many times will grogg's result be an integer?
Since 30² = 900 and 40² = 1600, between 30 and 40 of the numbers Grogg enters will reduce to integers. Now just find which count is correct. We don't have to look far:
31² = 961
32² = 1024
so there 31 of the outputs of √1, √2, √3, ..., √1000 are integers.
Grogg will result to integers with 31 outputs from √1, √2, √3, ..., √1000 .
What are integers?An integer serves as the whole number which can be a positive or negative numbers , such as 6, 9, but it cannot be a fraction.
since, she is starting from √1, √2, √3, up to √1000 , then we know that
31² = 961, then we can find the correct count which is 31. so if she is to input those number into square root one after the other , she will have 31 count.
Therefore, Grogg will result to integers with 31 outputs from √1, √2, √3, ..., √1000 .

minutes.
A=-2.3t-7A=−2.3t−7A, equals, minus, 2, point, 3, t, minus, 7
How fast did Mr. Mole descend
Using the slope of the linear function, it is found that Mr. Mole descends 2.3 meters per minute.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, Mr. Mole's altitude in meters after t minutes is given by:
A = -2.3t - 7.
The rate of change is the slope of m = -2.3, hence, Mr. Mole descends 2.3 meters per minute.

at a constant rate? Check all of the boxes that apply.
y - 6 = 3(x – 10)
y- 16 = 3(x-9)
y = 3x - 11
y=-3x-23
D
DONE
Answer:
(b) y -16 = 3(x -9)(c) y = 3x -11Step-by-step explanation:
You are given a couple of points:
(years, heigh) = (6, 7) and (9, 16)
and asked to write a linear equation that they satisfy. In general, you need to find the slope using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (16 -7)/(9 -6) = 9/3 = 3
__
point-slope equationThe point-slope form of the equation for a line can be used with this information.
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
Using the given points, you can write either of the equations ...
y -7 = 3(x -6) . . . . . using the first point
y -16 = 3(x -9) . . . . . using the second point. This matches choice B.
__
slope-intercept equationEither of the point-slope equations can be rearranged to give the slope-intercept equation.
y -16 = 3(x -9)
y = 3x -27 +16 . . . . eliminate parentheses, add 16
y = 3x -11 . . . . . This matches choice C.

Additional comment
The first choice has the right slope, but uses a point not on the line (10, 6).
The last choice has the wrong slope and the wrong y-intercept.

The cost for the cylindrical container will be $2.8 and for the conical container, $0.94 and the difference is $1.86
What is volume?Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like radius length in the case of cylinders and cones.
Given that:-
The cost per cubic inch is $0.10 for each container’s contentsThe volume of a cylinder:-
V = πr²h
V = π x (1.5)² x 4 = 28.27 cubic inches
So the cost will be = 28.27 x 0.10 = $2.8
The volume of the cone:-
V = (1 / 3 ) πr²h
V = (1 / 3 ) π x ( 1.5 )² x 4 = 9.42 cubic inches
The cost will be = 9.42 x 0.10 = $0.94
The difference between the two costs will be:-
= $ 2.8 - $0.94
= $1.86
Therefore the cost for the cylindrical container will be $2.8 and for the conical container, $0.94 and the difference is $1.86

From his eye, which stands 1.64 meters above the ground, Keshawn measures the angle of elevation to the top of a prominent skyscraper to be 33 degrees. If he is standing at a horizontal distance of 385 meters from the base of the skyscraper, what is the height of the skyscraper? Round your answer to the nearest tenth of a meter if necessary.
The height of the scyscraper will be equal to H=251.66 meters
What is trigonometry?The branch of mathematics set up a relatioship between the angle and the sides of the right angle triangle is called as trigonometry.
Here we have the following data:-
The height of the observer's eye=1.63 meters
The angle which eye is making withe the building=33
The horizontal distance = 385 meters
So the height of the building is calculated as:-
[tex]Tan\theta=\dfrac{P}{B}\\\\\\tan\theta=\dfrac{H-1.64}{385}\\\\ \\\\tan33=\dfrac{H-1.64}{385}\\\\\\\\[/tex]
H=251.66 meters

Which relationships have the same constant of proportionality between y and x as in the equation?
Select all that apply
I know from the charts it's C but from the latest tables I don't know.
*Correct Question:
Which relationships have the same constant of proportionality between y and x as the equation 3y=27x?
Answer:
A, B, C
Step-by-step explanation:
Given that [tex]3y=27x[/tex], we can simplify to get a proportionality statement that exists between X and y. Thus
[tex]3y=27x[/tex]
Divide both sides by 3
[tex]\frac{3y}{3}=\frac{27x}{3}[/tex]
[tex]y=9x[/tex]
Thus, we can say, y would always be 9 times the quantity of x.
From the options given, examine which options have this proportionality statement as well.
Option A, y = 9x is same as the statement.
Option B, 2y = 18x, conforms to the same statement. If we simply further, we would have y = 9x
Option C, the graph shows that when x = 1, y = 9. This also confirms to the same constant of proportionality in the given equation.
Option D and E do not have same constant of proportionality.
The right options are A, B, and C.
