The answer to this question will t = 8. The first step to solving this equation is to combine the like terms by adding the two numbers together.
In this case, 5t + 35 = 40t. The next step is to divide both sides of the equation by the coefficient of the variable, which in this case is 5. When you do this, you get 40t/5 = t. Therefore, the answer to 5t + 35 is t = 8.
A coefficient is an integer that is either multiplied by the variable it is associated with or written alongside the variable. A coefficient is, in other words, the numerical factor of a term that contains both constants and variables. For instance, the coefficient in the expression 2x is 2.

determine whether each table represents a linear or non-linear function explain
Each of the tables is classified as linear or non-linear on the image presented at the end of the answer.
How to classify the functions as linear or non-linear?A function is classified as linear or non-linear depending on the rate of change of the function.
If the rate of change of the function is constant, that is, when x changes by one amount, y always changes by the same amount, then the function is classified as linear.
Conversely, if the rate of change of the function is different for different intervals, then the function is classified as non-linear.
For example, the top-left function is non linear, as when x changes by one from x = 1 to x = 2, y changes by 3, from y = 1 to y = 4, while when x changes by one from x = 2 to x = 3, y changes by 5.
The bottom-right function is linear, as for each increase of x by 5, the value of y decays by 4.

Please help!!! Very confused on my homework.
The tank is completely filled with water and then drains completely into the pool. The volume of the cylindrical tank is v1=36pir2/1 where r1 is the radius of the tank in feet.
PROBLEM IS ON THE ATTACHMENT!
Step-by-step explanation:
we need to use both equations for the volumes.
the only variables in them are r1 and r2.
when we say both results (volumes) are equal, that means we can create an equation with one formula on one side and the other formula on the other side.
and then we can easily transform the equation into "r1 = ..." or "r2 = ..."
and yes, your teacher made a mistake by hinting to solve for r1 in a. and b. it is r1 in a. and r2 in b.
a.
the goal here is an equation in the form
"r1 = ..."
that means r1 is a function of r2.
36×pi×r1² = 1/2 × 4/3 × pi × r2³ = 4/6 × pi × r2³ =
= 2/3 × pi × r2³
36 × r1² = 2/3 × r2³
r1² = (2/3 / 36) × r2³ = (1/(3×18)) × r2³ = 1/54 × r2³
r1 = sqrt(1/54 × r2³) = 1/3 × sqrt(1/6 × r2³)
b.
the goal here is
"r2 = ..."
again
36×pi×r1² = 2/3 × pi × r2³
36 × r1² = 2/3 × r2³
3×36 × r1² = 2 × r2³
3×18 × r1² = r2³
54 × r1² = r2³
[tex]r2 = \sqrt[3]{54 \times {r1}^{2} } = 3 \times \sqrt[3]{2 \times {r1}^{2} } [/tex]
c.
r2 is doubled.
so, we have to go back to our equation of a.
r1 = sqrt(1/54 × r2³).
when r2 is doubled, we get
r1 = sqrt(1/54 × (2×r2)³) = sqrt(1/54 × 8 × r2³) =
= sqrt(8) × sqrt(1/54 × r2³)
so, when r2 doubles, r1 has to grow by the factor of sqrt(8) to keep the equality intact.

A rigid body exists in an n-dimensional space. How many coordinates are needed to specify the position and orientation of this body in this space
The number of coordinates needed to specify the position and orientation of a rigid body in an n-dimensional space is n.
A rigid body is an object that maintains its shape and size while in motion. In order to specify the position and orientation of a rigid body in an n-dimensional space, we need to know its coordinates in each of the n dimensions. The coordinates describe the location of the body in the space and the orientation of the body relative to the space's coordinate system. Thus, n coordinates are required to fully specify the position and orientation of a rigid body in an n-dimensional space.
However, it is important to note that if the rigid body is placed in a space that's non-Euclidean, other parameters could be necessary to fully describe the rigid body position and orientation.

What is the slope of the line containing (-3, 5) and (6, -1)?
A. 2/3
B. 1
C. -1
D. -2/3
Answer:Slope is -2/3
Step-by-step explanation:
What you do is use the formula y2-y1/x2-x1.
y1 and y2 are at the end of the parenthesis so y1 is 5 and y2 is -1.
x1 and x2 are at the beginning of the parenthesis so x1 is -3 and x2 is 6.
Then you put it into the formula:
-1-5/6-(-3)
This then equals -2/3.
-2/3 is the answer.
In ΔEFG, g = 8.4 inches, mm∠G=79° and mm∠E=25°. Find the length of f, to the nearest 10th of an inch.
The 8.4 inches length of g and the 79° and 25° measures of the angles ∠G and ∠E, using the law of sines, indicates that the length of the side EG = f is about 8,3 inches.
What is the law of sines?The law of sines states that the ratio of the sine of an interior angle of a triangle to the length of the opposite side to the angle is the same for the three sides and angles in a triangle.
Mathematically, the law of sines can be presented as follows;
[tex]\dfrac{a}{sin(A)} = \dfrac{b}{sin(B)} =\dfrac{c}{sin(C)}[/tex]
Where;
a, b, and c are the length of each of the sides of the triangle, and ∠A, ∠B, and ∠C are the measure of each of the interior angles of the triangle.
The details of the triangle ΔEFG, specifying the side g as the side opposite the angle ∠G, and the side f as the side opposite the ∠F we get;
The length of EF = g = 8.4 inches
Length of EG = f
The angle sum property of a triangle indicates that we get;
∠E + ∠F + ∠G = 180°
∠F = 180° - (∠E + ∠G)
∠F = 180° - (25° + 79°) = 76°
According to the law of sines, we get;
8.4/(sin(79°) = f/(sin(76°))
f = (sin(76°)) × 8.4/(sin(79°) ≈ 8.3

What is the Pythagorean triplet of 16?
The Pythagorean triplet of 16 is (8, 15, 17).
This can be calculated using the Pythagorean theorem, which states that in any right triangle, the sum of the squares of the two legs is equal to the square of the hypotenuse. Therefore, given a number, we can find a Pythagorean triplet by calculating the squares of the two legs and then finding the hypotenuse.
Formula:
a² + b² = c²
Find the square of the number.
16² = 256
Subtract the square from the number to get one leg of the triangle.
16 - 256 = -240
Take the square root of the result.
√(-240) = 8
Add the square to the number to get the other leg of the triangle.
256 + 16 = 272
Take the square root of the result.
√(272) = 15
Add the two legs together to get the hypotenuse.
8 + 15 = 23
Take the square of the result.
23² = 529
Subtract the sum of the two legs from the hypotenuse.
529 - 23 = 506
Take the square root of the result.
√(506) = 17
Therefore, the Pythagorean triplet of 16 is (8, 15, 17).

What is the easiest way to learn linear equations class 8?
The easiest way to solve linear equations is to use the elimination method.
A linear equation is an equation that has two variables and when it is graphed it gives a straight line. Linear equations can be graphed according to their slope and y-intercept. The standard equation for a line is y = mx + b, where b is the y-intercept and m is the slope.
To solve linear equations in the easiest and simplest way use the elimination method. In this method, you either add or subtract the equations to obtain an equation in one variable. When the coefficients of one variable are opposites, you add the equations to eliminate a variable and when the coefficients of one variable are equal, you subtract the equations to eliminate a variable.

hlork out the nice of the e-scooter in the sale
a) Issac get £10.75 as change after buying all masks
b) The price of the e-scooter in the sale is £277.50
a)
Isaac buys 17 anti-pollution masks for £5.25 each, so the total cost is
17 * 5.25 = £89.25
He pays with five £20 notes, which is a total of 5 * 20 = £100
So, the change he should get is £100 - £89.25 = £10.75
Therefore, Isaac should get £10.75 as change.
b)
In the sale, there is 1/4 off the cost price of the e-scooter, which means that the scooter is discounted by 1/4 * £370 = £92.50.

The sum of the measures of the interior angles of a polygon is 5 times the sum of the measures of the exterior angles. How many sides does the polygon have
Answer:
polygon has 12 sides
Step-by-step explanation:
the sum of the exterior angles of a polygon is 360°
the sum of the interior angles of a polygon is
sum = 180° (n - 2 ) ← n is the number of sides
given the sum of the interior angles is 5 times sum of exterior angles, then
sum = 5 × 360° = 1800° then
180° (n - 2) = 1800 ( divide both sides by 180 )
n - 2 = 10 ( add 2 to both sides )
n = 12
Thus the polygon has 12 sides
