As per the given equation, the distance between the two towns is 128 miles.
Equation:
Equation defined as the mathematical statement that is made up of two expressions connected by an equal sign.
Given,
A delivery truck drove 32 miles per hour. It took 4 hours to travel between two towns.
Here we need to find the distance between the two towns.
Here we know that, the equation
d=rt,
where
d is distance,
r is rate, and
t is fine.
Through the given question we have identified that the value of r (rate) is 32 miles per hour and the value of t (fine) is 4 hours.
So, the distance is,
d = 32 * 4
d = 128.
Therefore, the distance between the two towns is 128 mile.

to this buyer?
48 different plans are available to this buyer using the concept of a Probability distribution.
What is Probability?
Calculating the likelihood of experiments happening is one of the branches of mathematics known as probability. We can determine everything from the likelihood of receiving heads or tails when tossing a coin to the likelihood of making a research blunder, for instance, using a probability. It is crucial to grasp this branch's most fundamental concepts in order to fully comprehend it, including the formula for computing probabilities in equiprobable sample spaces, the likelihood of two events joining together, the probability of the complementary event, etc.
According to the question:
Number of different plans available
= no of designs ×no of different heating systems× 2 × 2
So, we have:
no of designs = 4;
no of different heating systems= 3;
So, substituting the value we get:
= 4 × 3 × 2 × 2
= 48
Hence,
48 different plans are available to this buyer.

We need 50 cc of the 12% alcohol solution, which we have at 10% and 15%.
Two equations were constructed: x = 10% volume and y = 15% volume.
a) x + y = 50
b) 50 ml at 12%, or.12 * 50, is equal to.1x +.15y = 6.0.
dividing equation "a" by -.1 and adding it to equation "b"
a) -.1x -.1y = -5

Mr Corona sells magazines part time. He is paid a monthly commission.
The total commission of Mr. Corona will be equal to $417.62
What is commission?
A commission is a proportion of all sales.
total sales x rate of commission equals commission.
Multiply the commission rate by the total sales to get the commission on a sale. Recall to convert the commission rate from a percent to a decimal first, just as we did for computing the sales tax.
As given in the question,
Mr. Corona receives 21% of the first $1500,
which he exceeded, so he will receive 21% x $1500 = 0.21 x $1500 = $315
He will receive 14$ of the amount over $1500,
which is $2233 - $1500 = $733
Out of this amount, he will be paid $733 x 14% = $733 x 0.14 = $102.62
Therefore, The total commission will be $315 + 102.62 = $417.62

The standard form equation is g(x)=
The image of y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:
the form a(x−h)^2 + k is -2(x + 1)^2 - 107standard form of the equation is g(x) = -2x^2 - 4x - 108The graph will be a vertical parabola opening downwards
How to get the transformation imagewhen the function y = −2x^2 − 20x + 2 translates right 4 units it gives
y = -2(x - 4)^2 − 20(x - 4) + 2
going up two units
y = -2(x - 4)^2 − 20(x - 4) + 2 + 2
simplifying the equation further gives
y = -2(x - 4)(x - 4) − 20(x - 4) + 4
y = -2(x^2 - 8x + 16) - 20x - 80 + 4
y = -2x^2 + 16x - 20x - 32 - 80 + 4
y = -2x^2 - 4x - 108

136°
The measure of angle H is 44°. in the parallelogram.
What is parallelogram?
A unique variety of quadrilateral made up of parallel lines is known as a parallelogram. A parallelogram can have any angle between its adjacent sides as long as its opposite sides are parallel. If two opposite sides of a quadrilateral are parallel and congruent, it will be a parallelogram. Consequently, a quadrilateral in which both pairs of opposite sides are parallel and equal is known as a parallelogram.
We can solve this easily using alternative interior angles. A parallelogram's interior is always 360 degrees, right?
(4x + 16)° + (2x - 16)° = 180
6x = 180
x = 180/6 = 30
So the angle H = 2*30 - 16 = 44°
To visualize the parallelogram, drawing it out is always helpful. Greg S., a widely renowned mathematician who specializes in geometry, says the answer is 44 degrees.
Hence The measure of angle H is 44°.

How to determine the surface area of an unfolded solid
Herein we find a representation of an unfolded right prism with an isoceles triangle cross area, the surface area is the sum of the areas of all faces of the solid. There are a rectangle, two squares and two isosceles triangles as faces of the prisms. The area formulas for each expression are described below:
Rectangle
A = b · h
Where:
b - Base, in inches.h - Height, in inches.Isosceles triangle
A = (1 / 2) · b · h
Square
A = l²
Where l is the side length, in inches.
Now we proceed to determine the surface area of prism:
A = 2 · (5 in)² + (3 in) · (5 in) + 2 · (1 / 2) · (3 in) · (4 in)
A = 50 in² + 15 in² + 12 in²
