Answer:
4x4x4
Step-by-step explanation:
3x4x5= 60
4x4x4= 64
64 is a higher volume than 60
Answer:
In order to find out which box can hold more, we can find the respective volumes of the boxes.
Volume of first box
= 3 inches × 4 inches × 5 inches
= 60 inches³
Volume of second box
= 4 inches × 4 inches × 4 inches
= 64 inches³
∴Since the second box has a greater volume than the first box, the former can hence hold more than the latter.
A die is rolled. The set of equally likely outcomes is {1, 2, 3, 4, 5, 6}. What is the probability of rolling a 6?
Answer:
the probability of rolling a 6 is 1/6
Step-by-step explanation:
because there are six possible outcomes and it is a fair die, each outcome must be equally as likely, therefore there is a 1/6 chance of rolling any number.
A person is selected at random. A is the event “the person selected earns more than $100,000 per year” and B is the event “the person selected earns more than $250,000 per year.”
The pairs of events, A and B, that are disjoint include option A and B.
What are disjoint events?It should be noted that disjoint events simony means the events that are mutually exclusive as they can't occur at the same time.
For option A, because a person can be either male or female but not both, events A and B are disjoint.
For B, because the person already earns more than $100,000, events A and B are not disjoint.
For C, because the sum of two dice cannot be three when one die is three, events A and B are disjoint.
Therefore, A and C are disjoint.

What are the solutions to this system of conics?
Answer:
(1, -1) and (7, -1)===============
Given system(x − 4)² + (y + 1)² = 9(x − 4)² / 9 + (y + 1)² / 81 = 1Solve it by eliminationMultiply the second equation by 9 and subtract from the first one:
(y + 1)² - (y + 1)² / 9 = 0(y + 1)²/8 = 0(y + 1)² = 0y + 1 = 0y = - 1Substitute y and solve for x(x − 4)² + (-1 + 1)² = 9(x - 4)² = 9x -4 = ± 3x = 4 ± 3x = 1 and x = 7Answer:
[tex]\left(\; \boxed{1}\:,\boxed{-1}\;\right)\; \textsf{and}\;\left(\; \boxed{7}\:,\boxed{-1}\;\right)[/tex]
Step-by-step explanation:
Given system of conics:
[tex]\begin{cases}(x-4)^2+(y+1)^2=9\\\\\dfrac{(x-4)^2}{9}+\dfrac{(y+1)^2}{81}=1\end{aligned}[/tex]
Multiply the second equation by 81:
[tex]\implies \dfrac{81(x-4)^2}{9}+\dfrac{81(y+1)^2}{81}=81[/tex]
[tex]\implies 9(x-4)^2+(y+1)^2=81[/tex]
Rearrange to make (y + 1)² the subject:
[tex]\implies (y+1)^2=81-9(x-4)^2[/tex]
Substitute into the first equation and simplify:
[tex]\implies (x-4)^2+81-9(x-4)^2=9[/tex]
[tex]\implies -8(x-4)^2=-72[/tex]
[tex]\implies (x-4)^2=9[/tex]
Solve for x:
[tex]\implies \sqrt{ (x-4)^2}=\sqrt{9}[/tex]
[tex]\implies x-4=\pm3[/tex]
[tex]\implies x=4\pm3[/tex]
[tex]\implies x=1, 7[/tex]
Substitute the found values of x into the first equation and solve for y:
[tex]\begin{aligned}x=1 \implies (1-4)^2+(y+1)^2&=9\\(-3)^2+(y+1)^2&=9\\9+(y+1)^2&=9\\(y+1)^2&=0\\y+1&=0\\y&=-1\end{aligned}[/tex]
[tex]\begin{aligned}x=7 \implies (7-4)^2+(y+1)^2&=9\\(3)^2+(y+1)^2&=9\\9+(y+1)^2&=9\\(y+1)^2&=0\\y+1&=0\\y&=-1\end{aligned}[/tex]

Contains the points (5, 3) and (8, 12); slope-intercept form
Answer:
y = 3x + 12
Step-by-step explanation:
y = mx + b
The m is the slope and the b is the y intercept.
Slope:
Change in y over the change in x. The ordered pair is written in the form (x,y)
[tex]\frac{12-3}{8-5}[/tex] = [tex]\frac{9}{3}[/tex] = 3
The slope is 3.
Use the slope of the 3 and the x and y from one of the ordered pairs given. I am going to use the point (5,3), but either point will work
slope 3
x = 5
y=3 Plug these all in and solve for b
y = mx + b
3 = (3)5 + b
3 = 15 + b Subtract 15 from both sides
-12 = b
This is the y intercept
y = 3x - 12
Answer:
Slope-intercept form,
→ y = 3x - 12
Step-by-step explanation:
Formula we use,
→ y = mx + b
The value of slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (12 - 3)/(8 - 5)
→ m = 9/3
→ [ m = 3 ]
Then the value of b will be,
→ y = mx + b
→ 12 = (3)8 + b
→ b + 24 = 12
→ b = 12 - 24
→ [ b = -12 ]
Now the slope-intercept form is,
→ y = mx + b
→ [ y = 3x - 12 ]
Hence, the answer is y = 3x - 12.

Which relation is a function?
Answer:
The bottom right
Step-by-step explanation:
A relation is just a set of ordered pairs. A function is a special relation. In a function every input (x) has only one output (y).
You can use the vertical line test. If you took your pencil and vertical passed over the graph left to right. If there is any point that more than one point would be under the pencil, the relation is not a function.
in exercises 10-11, find the value of x so that the function has the given value.
10. m(x) = -3/5x - 4; m(x) = 2
11. w(x) = 5/6x - 3; w(x) = -18
The value of x so the the the function has the given value is as follows:
m(x) = 2; x = - 10w(x) = - 18; x = - 18How to find the value of the input of a function?A function relates an input to an output.
In other words, a function is a special relationship among the inputs and their outputs codomain) where each input has exactly one output value.
Therefore, let's find the value of x so that the function has the given values.
m(x) = -3/5x - 4; m(x) = 2
let's find the value of x when m(x) = 2
2 = - 3/5x - 4
2 + 4 = - 3/5x
6 = - 3/5 x
cross multiply
-3x = 30
x = 30 / - 3
Hence,
x = - 10
w(x) = 5/6x - 3; w(x) = -18
let's find the value of x when w(x) = -18
- 18 = 5/6x - 3
- 18 + 3 = 5 / 6 x
- 15 = 5 / 6 x
5x = - 90
x = -90 / 5

A) 610
B)520
C)350
D)300
The total number of cattle Frank currently owned could be C)350
How to find the total number of cattle Frank currently ownedThe problem is asking multiples of 7.
Multiples of 7 come into play after working the the percentage as follows
Frank sold 30%, the percentage left is
= 100% - 30%
= 70%
= 0.7
The multiple of 7 that is a number 7 will divide without remainder here is 350 and this is the correct answer.

3. Output rule: y = 3 if |x| is even, y = 1 if |x| is odd. Classification: Neither.
What defines a linear function?A linear function is defined when the increase of 1 in x result in the addition of a constant to y, hence the rule is:
y = mx + b.
In which:
m is the addition to y when x increases by one.b is the value of y when x = 0.Hence, for the first table, as 5 is added to x when x increases by one, the rule is:
y = f(x) = 5x + 16.
What defines an exponential function?An exponential function is defined when the increase of 1 in x result in the multiplication of a constant to y, hence the rule is:
y = a(b)^x.
In which:
b is the addition to y when x increases by one.a is the value of y when x = 0.Hence, for the second table, the rule is:
y = 2^x.
For the third table, none of the definitions for linear and for exponential functions are true, hence the function is neither, as it is a piece-wise function that assumes one value for odd numbers and another for even numbers.

If <1 and <2 are supplementary and m <1 = 67 degrees , what is m<2?
Answer:
D
Step-by-step explanation:
supplementary angles sum to 180° , that is
∠ 1 + ∠ 2 = 180°
67° + ∠ 2 = 180° ( subtract 67° from both sides )
∠ 2 = 113°
