296 rounded to the nearest hundred would be 300 and 2423 would be 2400 there hope it helps
The product of 296 and 2.423 rounded to the nearest hundred would be 717.20
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of trimmed from the right in terms of exact digits.
We need to find the product of 296 and 2.423
296 x 2.423 = 717.20
Thus, 717.20 rounded to the nearest hundred .

What is the interquartile range of this data 0, 5, 10, 15, 20,
Answer:
15
Step-by-step explanation:
The range from Q1 to Q3 is the interquartile range (IQR).
The interquartile range is the difference between the third and first quartiles.
The third quartile is 17.5.
The first quartile is 2.5.
The interquartile range = 17.5 - 2.5 = 15.

Given 2 points, fill in the slope formula
and calculate the slope of the equation.
(4, 6); (7, 12)
Answer:
Slope formula:
RISE: y2(second y-coordinate) - y1(first y-coordinate)
____________________________________
RUN: x2(second x-coordinate) - x1(first x-coordinate)
y2 - y1 / x2 - x1
Plug in what we have in the order given in the formula:-
12 - 6 6
______ = ______, which simplifies to 2.
7 - 4 3
Therefore, 2 is the slope of this equation.
Answer:
Slope: 2
Step-by-step explanation:
Given points:
(4, 6)(7, 12)Slope formula: (y₂ - y₁)/(x₂ - x₁)
1. Substitue the coordinates of the points in the formula, which will determine the slope of the two points:
[Formula] Slope = (y₂ - y₁)/(x₂ - x₁)[Substitute] Slope = (12 - 6)/(7 - 4)2. Simplify the fraction. The quotient will be the slope of the line.
[Simplify] Slope = (6)/(3) = 2Thus, the slope of the line is 2.
if two angles in a triangle are 50 and 40, it must be a/an___________________triangle.
Answer:
right triangle
Step-by-step explanation:
Hey there!
A triangle has to have three vertices that add up to 180 degrees
The angle measurments 50 and 40 are already given and added up, they equal 90 degrees
Now out of 180 degrees, 90 degrees is already shown
What you need to do now is try to find how much more degrees you need to get 180 degrees
As you know 180-90=90
So this means that the missing angle is 90 degrees
Now that we know this, we can find out what type of triangle this is
Since the triangle has an angle that is equal to 90 degrees, or it has a right angle, the triangle can be called a right triangle
A right triangle is a triangle that has an angle that is equal to 90 degrees
So this triangle is a right triangle

Can I have help in the next few minutes?
there are 3 blanks i need the info for
Answer:
a) (2x + 1)(3x - 4)
b) 546
Step-by-step explanation:
a)
We need to try to factor the polynomial.
6(-4) = -24
6x² - 8x + 3x - 4 = 2x(3x - 4) + 1(3x - 4) =
= (2x + 1)(3x - 4)
b)
6(10)² - 5(10) - 4 = 600 - 50 - 4 = 546
Answer:
(a) when x = 2: width = 2 units and length = 5 units
(b) 546 units²
Step-by-step explanation:
Given expression:
[tex]6x^2-5x-4[/tex]
Part (a)
To factor a quadratic in the form [tex]ax^2+bx+c[/tex]
Find 2 two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]
Two numbers that multiply to -24 and sum to -5: -8 and 3
Rewrite [tex]b[/tex] as the sum of these 2 numbers:
[tex]\implies 6x^2+3x-8x-4[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies 3x(2x+1)-4(2x+1)[/tex]
Factor out the common term [tex](2x+1)[/tex]:
[tex]\implies (3x-4)(2x+1)[/tex]
Therefore:
[tex]\implies x=\dfrac{4}{3}, \: x=-\dfrac{1}{2}[/tex]
As distance is positive, [tex]x > \dfrac{4}{3}[/tex]
Let [tex]x=2[/tex]
[tex]\implies (3(2)-4)(2(2)+1)[/tex]
[tex]\implies (2)(5)[/tex]
Therefore, possible dimensions of the rectangle are:
width = 2 units
length = 5 units
Part (b)
Substitute [tex]x=10[/tex] into the equation:
[tex]\begin{aligned}\implies 6(10)^2-5(10)-4&=600-50-4\\&=546\end{aligned}[/tex]

how do you find the volume for a dome, pyramid, and a cylinder.
Write the equation
for this line in
slope-intercept form.
y = ?/?x+ ?
Answer:
y = 2/3x - 1 (or y = 2/3x + -1 to fit the graphic)
Step-by-step explanation:
Slope intercept form is written as (y = mx + b) where m is slope and b is the y intercept.
First you need to find the slope, m. We'll use the two points (-3, -3) and (3, 1)
m = (y2 - y1) / (x2 - x1)
m = (1 - (-3)) / (3 - (-3))
m = 4/6
m = 2/3
Next we need the y intercept, b. On the graph we can see that is -1 but we can also find it substituting the known slope and one point on the line for our values to solve for b. We'll use (3, 1) as the point.
y = mx + b
1 = 2/3 * 3 + b
simplify 2/3 * 3
1 = 2 + b
subtract 2 from both sides
-1 = b
Now we have all the values we need to plug into our slope intercept equation (m = 2/3, b = -1)
y = mx + b
y = 2/3x - 1
[tex]\sf{y=\displaystyle\frac{2}{3} x-1[/tex]
Solution:We are given two points: (3, 1) and (-3, -3).We can use these points to find the slope of the line:m=[tex]\displaystyle\frac{y2-y1}{x2-x1}[/tex][tex]\displaystyle\frac{-3-1}{-3-3} =\frac{-4}{-6} =\frac{2}{3} \longleftarrow\sf{slope}[/tex]Now, we need to identify the line's y-intercept.The y-intercept is the point where the graph touches the y-axis.Since the graph touches the y-axis at (0, -1) the y-intercept is equivalent to (0, -1) or -1.Hope it helps.

Help please calculus
Let x, y, and z denote the side lengths of the box, with the bottom face having dimensions x-by-y and z is the height. Naturally this means each of x, y, and z must be greater than 0.
The box has a fixed volume of 252 cm³, so
xyz = 252
The surface area of the box is
2xy + 2xz + 2yz
and we're told that the material cost for each face is different. The total cost of the material needed to make the box is given by
C (x, y, z) = ($5/cm²) xy + ($2/cm²) xy + 2 ($3/cm²) (xz + yz)
or, omitting units and simplifying,
C (x, y, z) = 7xy + 6 (x + y) z
In the volume constraint, solve for any one variable; I'll do z.
z = 252/(xy)
Substitute this into the cost function:
C (x, y, 252/(xy)) = 7xy + 1512 (x + y)/(xy)
Since this is now a function of 2 variables, I'll rewrite this as
C* (x, y) = 7xy + 1512 (1/y + 1/x)
Compute the partial derivatives of C and find the critical points:
∂C/∂x = 7y - 1512/x² = 0 ⇒ x² y = 216
∂C/∂y = 7x - 1512/y² = 0 ⇒ x y² = 216
It follows that
x² y = x y² ⇒ x = y
Just like before, we can think about C* as yet another function but only of 1 variable,
C** (x) = 7x² + 3024/x
Now find the critical points of C** :
dC**/dx = 14x - 3024/x² = 0 ⇒ x = 6
All of this tells us that C (x, y, z) has a critical point when x = y = 6 and z = 252/6² = 7. So the box that costs the least has dimensions 6 × 6 × 7 cm, which gives the box a surface area of 240 cm² and a total cost of $756.

total of 57 granola bars. If each box contains the same number of bars, how many bars are in
each box?
Answer:
13.5
Step-by-step explanation:
total boxes of granola is = 3 + 2 + 1
= 6 boxes
6 boxes = 57 bars
1 box = 57 / 6
1 box = 9.5 + 3
