The statement that is not true about the angles in the triangle is OPTION C. The measure of ∠K is 89°

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

From the diagram:

∠J + ∠K + ∠L = 180° (angles in a triangle)

Substituting:

(7x + 2) + (8x) + (4x + 7) = 180

19x + 9 = 180

x = 9

∠J = 7x + 2 = 7(9) + 2 = 65°

∠K = 8x = 8(9) = 72°

∠L = 4x + 7 = 4(9) + 7 = 43°

∠k ≠ 89°

The new workshop can produce as many as 180 toys each year compared to the old workshop

The approximation of numbers is the estimates of the said number.

This means that the approximation of a number is close to the said number, but it has a slight different value

The given parameters are:

Old capacity = 22,912,546,992 toys per year

New capacity = 4,134,232,638,937 toys per year

The approximate number of times is calculated as

Number of times = New capacity/Old capacity

Substitute the known values in the above equation

So, we have

Number of times = 4,134,232,638,937 toys per year/22,912,546,992 toys per year

Remove the units

So, we have

Number of times = 4,134,232,638,937/22,912,546,992

Evaluate the quotient

So, we have

Number of times = 180.435315217

Approximate

Number of times = 180

The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24

The entire family can participate in tubing. Change into swimwear, rent a tube and a life jacket, and float down the river—that it's easy. Numerous outfitters provide transportation to the best waterways and rent tubes from Blue Ridge to Columbus, via Helen and Columbus.

The total cost of rent on tube = $360

Price of regular tube = $15

Price of cooler tubes = $7.5

Let the no. of regular tubes be and cooler tubes be y

The equation forms

15x + 7.5y = 360           ...1

As we can notice regular tube is twice the price of cooler tubes, sthe the equation forms

2(7.5) = 15

This means when y = 2, x = 1

cross multiply them and we find

2/y = 1/x

x/y = 1/2

x = y/2               ...2

Putting the value of x in eq 1, we get

15(y)/2 + 7.5y = 360

7.5y + 7.5y = 370

15y = 360

y = 360/15

y = 24

Putting the value of y in eq 1, we get

15x + 7.5(24) = 360

15x + 180 = 360

15x = 360 - 180

15x = 180

x = 180/15

x = 12

Thus, The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24.

Answer:

f(-10) = -299999

Step-by-step explanation:

Equation

f(x)= −3x^55+1

Given

x = - 10

Solution

You have to understand what f(x) means. When you put a value in for x, every x on the right is supplied with that value.

In this case I take the equation to mean what ever we are given in the brackets (in this case 10) is what goes into the x on the right. So the new equation is

f(-10) = -3*(-10)^5 + 1

(- 10) ^5 = - 100000

f(-10) = -300000 + 1

f(-10) = -299999

For every 500 g of reactants, 3.1 g of catalyst were required. The catalyst that was required for 900 g of reactant was 5.58g

The process of catalysis involves introducing a catalyst to chemical reaction to speed up the process. Catalysts are not destroyed during reaction and are unaffected by it. Very little amounts of catalyst are frequently sufficient when the reaction is swift and the catalyst recycles quickly; the velocity of the reaction is greatly influenced by mixing, surface area, and temperature. In most cases, catalysts interact with one or more reactants to produce intermediates that ultimately lead to the final reaction product, regenerating the catalyst in the process.

Homogeneous catalysis, in which all of the components are dispersed in the same phase as the reactant (often a gas or liquid), and heterogeneous catalysis, in which the components are not. It's common to think of enzymes and other biocatalysts as a a third category.

In all branches of the chemical business, catalysis is commonplace. 90% of all chemical compounds manufactured for commercial purposes are thought to use catalysts at some point during the manufacturing process.

500g of reactants = 3.1g of catalyst

1g of reactants = 3.1g of catalyst / 500g of reactants

The special angle pair relationship between ∠2 and ∠3 is same-side interior angles.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, linear angles, vertically opposite angles etc.

Therefore, the angle pair relationship between angle 2 and 3 are same side interior angles.

The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary.

Supplementary angles are those angles that sum up to 180 degrees. In other words, If the measures of two angles sum up to 180°, they are called supplementary angles.

Therefore, same side interior angles are supplementary angles.

The value of  m²+n²+p² is 46.

In mathematics, an identical element, also known as a neutral element, is an element of a set that, when subjected to a binary operation, leaves each element of the set intact. In algebraic structures like groups and rings, this idea is applied. Algebraic identities are algebraic equations that are true regardless of the value of each variable. Additionally, they are employed in the factorization of polynomials. Algebraic identities are employed in this manner for the computation of algebraic expressions and the solution of various polynomials.

Given Data

m + n+ p= 10

mn + np + mp = 27

For m² + n²+ p²

Using algebraic identities,

(m+ n +p)² = m² + n² + p² +2(mn + np + pm)

(10)² = m² +n² + p² + 2(27)

100 = m² + n² + p² + 54

100 - 54 = m² + n² + p²

The measures of angle 1 and 2 can be found as follows:

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.

Therefore,

∠1 + ∠2 = 180(sum of angle on a straight line)

∠1 = 118(alternate angles)

118 + ∠2  = 180

∠2 = 180 - 118

∠2 = 62 degrees
