the number of pennies that Ella has in all is 500 pennies.
Number of stickers = 50
Cost of each sticker = 10 pennies
Now, we need to find the total pennies Ella has.
We will use multiplication to find the same.
So, by using the operation of multiplication, we get that:
Number of pennies = 10 × 50 pennies.
Number of pennies = 500 pennies.

Write in point-slope form an equation of the line through each pair of points. (0,-1) and (3,-5)
The equation of the line in point-slope form, which passes through the pair of points located at (0 , -1) and (3 , -5), is y + 5 = -4/3(x - 3).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Getting the slope of the two points: (0 , -1) and (3 , -5).
m = (y2 - y1)/(x2 - x1)
m = (-5 - -1)/(3 - 0)
m = -4/3
Using the point slope form, plug in the values of the slope and one point to set up the equation.
(y - y1) = m(x - x1)
where m = -4/3 and (x1 , y1) = (3 , -5)
(y - -5) = -4/3(x - 3)
y + 5 = -4/3(x - 3)

Naturally occurring element x exists in three isotopic forms: x-28 (27.979 u, 77.11 bundance), x-29 (28.976 u, 8.00 bundance), and x-30 (29.974 u, 14.89 bundance). calculate the atomic weight of x.
28.1 amu is the atomic weight of x.
What is atomic weight defined as?
The term "atomic weight" refers to an atom's overall weight. With the addition of a small amount from the electrons, it is roughly equal to the sum of the protons and neutrons.
What does atomic weight vs. atomic mass mean?
Atomic mass is the measure of the mass of a single atom or isotope. The average mass of an element in relation to all of its isotopes and their relative abundances is known as its atomic weight. The atomic masses of isotopes have no bearing on atomic mass.The atomic weight of the element will be a weighted average of the isotopes based on the relative abundance:
(27.977 x 0.9221) + (28.976 x 0.0470) + (29.974 x 0.0309
) = 25.798 + 1.362 + 0.926

Arithmetic progression AP is the given sequence of 3,7,11,15, ............ The common difference is found to be (d = 4).
What is the arithmetic progression AP sequence?The difference between two numerical orders in Arithmetic Progression (AP) is a constant value. Another name for it is Arithmetic Sequence.
Then we'd come across some key terms in AP, which are denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)Some AP formulas are as follows:
As shown below, the AP could also be described in terms of common distinctions. a, a + d, a + 2d, a + 3d, a + 4d, ………. ,a + (n – 1) d.The method for calculating an AP's n-th term is as follows: an = a + (n − 1) × dThe following is the arithmetic progression sum formula: Sn = n/2[2a + (n − 1) × d].Now, for the given sequence is 3,7,11,15, ...........
Let us suppose the first term is'a₁' = 3.
Let us suppose 'a₂' = 7 is the second term.
Let us suppose the third term is 'a₃' = 11.
Let us suppose the fourth term be 'a₄' = 15.
d = a₂ - a₁
Substitute the values;
d = 7 - 3 = 4 ........(equation 1)
Now consider the other set;
d = a₃ - a₂
d = 11 - 7 = 4 .......(equation 2)
As a result, both equations are equal. It means that the common difference is the same, which is (d = 4).
Therefore, the asserted sequence is discovered to be in AP, and the value of a common difference is discovered to be (d = 4).

What is meant by the altitude of a triangle?In geometry, an altitude is a line that passes through two very specific points on a triangle: a triangle's vertex, or corner, and its opposite side at a right, or 90-degree, angle. The base is the opposite side. Triangles have three vertices and three opposite sides in common.
A triangle's altitude is the perpendicular drawn from the triangle's vertex to the opposite side. The altitude, also known as the triangle's height, forms a right-angle triangle with the base.
Since JM is at an altitude of ΔJLP, m ∠ JMP = 90
3x - 6 = 90

A prime number is a whole number greater than 1 whose only factors are 1 and itself. An element is a real number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Numbers that have more than two factors are called composite numbers.
Factorization:
In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler things of the same kind
Factorization may also refer to more general decompositions of a mathematical object into the product of smaller or simpler objects. For example, every function may be factored into the composition of a surjective function with an injective function. Matrices possess many kinds of matrix factorizations. For example, every matrix has a unique LUP factorization as a product of a lower triangular matrix L with all diagonal entries equal to one, an upper triangular matrix U, and a permutation matrix P; this is a matrix formulation of Gaussian elimination.

The shortest distance from A to C would be diagonally from A to C.
This comprises:
Two straight paths of equal length (shown in blue on the attached diagram).Half the circumference of the central circle (shown in red on the attached diagram).The length of the diagonal between A and C can be calculated using Pythagoras Theorem:

Congruent radii are found in congruent circles. Concentric circles share a common center.
What circles have congruent radii?Congruent circles contain congruent radii. Concentric circles all have the same center. A central angle has a center vertex and circle endpoints.
The distances OA and OB are both equal to the radius of the circle because all points on the circle are equidistant from O. OA = OB, to put it another way.
According to the definition of line segment congruence, segments OA and OB are congruent. This is known as the "wheel theorem," because it is responsible for the operation of wheels.
Because all points on a circle are the same distance from the center, and circle radii have one endpoint on the circle and one at the center, all circle radii are congruent by definition. Every circle has an outer diameter.
Congruent circles contain congruent radii (the plural of radius). Concentric circles all have the same center.

Two similar cylinders have heights of 75 centimeters and 25 centimeters. What is the ratio of the volume of the large cylinder to the volume of the small cylinder?
The ratio of the volume of the large cylinder to the volume of the small cylinder is 3:1.
We are given height of cylinders and the information that both the cylinders are same. So, the radius of cylinders will be same.
The formula for calculation of volume of cylinder is -
Volume = πr²h, where r is radius and h is height.
Ratio of the volume of the large cylinder to the volume of the small cylinder= πr²h(large):πr²h(small)
Ratio = πr²75:πr²25
Cancelling πr² from both numerator and denominator as it is common in both

M = 12 x 2 x 6.50 + 10 x 5 = $206.
Alex salary's is found as follows, considering the rate and the hour and a half for the weekend:
A = 5 x 1.5 x 7 + 7 x (6 + 5.75 + 4.5 + 6.75 + 5.5) = $252.
Hence Chris made the most money in the week.

A line has a slope of 6/5 and includes the points (-2, -3) and (r, 3). What is the value of r?
Answer:
r = 3
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]\large\boxed{y=mx+b}[/tex]
where:
m is the slope.b is the y-intercept.Given:
Slope = ⁶/₅Point = (-2, -3)Substitute the given slope and point into the formula and solve for b:
[tex]\begin{aligned}y & = mx+b\\\implies -3 & = \dfrac{6}{5}(-2)+b\\-3 & = -\dfrac{12}{5}+b\\-3 +\dfrac{12}{5} & = b\\\implies b & = -\dfrac{3}{5}\end{aligned}[/tex]
Substitute the given slope and found value of b into the formula to create an equation for the line:
[tex]\boxed{y=\dfrac{6}{5}x-\dfrac{3}{5}}[/tex]
Substitute the point (r, 3) into the equation and solve for r:
[tex]\begin{aligned}y & = \dfrac{6}{5}x-\dfrac{3}{5}\\\implies 3 & = \dfrac{6}{5}r-\dfrac{3}{5}\\5 \cdot 3& = 5 \cdot \left(\dfrac{6}{5}r-\dfrac{3}{5}\right)\\15 & = 6r-3\\15+3&=6r-3+3\\ 18 & = 6r\\\dfrac{18}{6} & = \dfrac{6r}{6}\\3 & = r\\ \implies r & =3\end{aligned}[/tex]
Solution
Therefore, the value of r is 3.
