Find the measure of angles 1 and 2
I really need to get this done by today!
The unknown angles are as follows:
∠1 = 118°∠2 = 62°How to find measures of angles?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
Therefore,
∠1 = 118 degrees
∠2 = 62 degrees.

The given pairs of lines have been identified as parallel, perpendicular lines or neither as explained below.
How to Determine if Two Lines are Parallel or Perpendicular?Two lines are parallel if they have the same slope (m), while they are perpendicular to each other if their slopes are negative reciprocal of each other.
The slope in a given equation of a line that is in slope-intercept form, y = mx + b, is represented as "m" in the equation.
1. y = 3x - 7 and y = 3x + 1 both have the same slope (m) of 3. They are parallel lines.
2. y = -2/5x + 3 and y = 2/5x + 8 both have the different slope (m), which are not negative reciprocal to each other. They are neither parallel nor perpendicular lines.
3. The slope of y = -1/4x is -1/4. The slope of y = 4x - 5 is 4. -1/4 is the negative reciprocal of 4. Therefore, the lines are perpendicular.
4. 2x + 7y = 28 can be rewritten as y = -2/7x + 4, the slope (m) is -2/7.
7x - 2y = 4 can be rewritten as y = 7/2x - 2, the slope (m) is 7/2.
-2/7 and 7/2 are negative reciprocals.
They are perpendicular lines.
5. The slope of y = -5x + 1 is -5.
x - 5y = 30 can be rewritten as y = 1/5x - 6, the slope is 1/5.
The lines are perpendicular.
6. 3x + 2y = 8 can be rewritten as y = -3/2x + 4, the slope (m) is -3/2.
2x + 3y = -12 can be rewritten as y = -2/3x - 4, the slope (m) is -2/3.
The lines are neither.
7. The slope of y = -4x - 1 is -4.
8x + 2y = 14 can be rewritten as y = -4x + 7, the slope is -4.
They are therefore parallel lines.
8. x + y = 7 can be rewritten as y = -x + 7, the slope (m) is -1.
x - y = 9 can be rewritten as y = x - 9, the slope (m) is 1.
The lines are perpendicular.
9. They have the same slope of 1/3. They are parallel lines.
10. They have different slopes that are not negative reciprocals, therefore, they are neither.
11. Their slopes are 1/2 and -2. Therefore, they are perpendicular lines.
12. They have the same slope of 3/4. They are parallel lines.
13. They have the same slope of 1. They are parallel lines.
14. Their slopes are -5/4 and 4/5. Therefore, they are perpendicular lines.
15. Their slopes are not negative reciprocals and are not the same, therefore, they are neither.
16. Their slopes are 1/2 and -2. Therefore, they are perpendicular lines.
17. They are both vertical lines, therefore they are neither.
18. x = 1 is a vertical line while y = -8 is a horizontal line that meets perpendicularly. Therefore, the lines are perpendicular.

Chang invested his savings in two investment funds. the $3000 that he invested in fund a returned a 2% profit. the amount that he invested in fund b returned a 7% profit. how much did he invest in fund b, if both funds together returned a 4% profit?
Using algebraic expression and equation, he invested $2000 in fund b.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Let x = amount he invested in fund b
If both funds together returned a 4% profit, then the sum of the profit in each investment is equal to 4% of the total investment.
$3000(0.02) + x(0.07) = (3000 + x)(0.04)
Solving for x,
$3000(0.02) + x(0.07) = (3000 + x)(0.04)
$60 + 0.07x = $120 + 0.04x

15. x = 2∛11
16 x = -4∛2
17 x = ± 10√3
18. x = ± 4 √3 √5
Step-by-step explanation:
13. x³ = 54
x = ∛4
Factor 54: 2 x 27
∛54 = ∛2 x ∛27
∛27 = 3
answer: 3∛2
14. x² = 96
x = ±√96
96 = 6 x 16
√16 = 4
√6
√96 = ± 4√6 = ± 4√2√3
15. x³ = 88
x = ∛88
88 = 8 x 11
∛88 = ∛8 x ∛11 = 2∛11
16. x³ = -128 means x has to be negative
x = -∛128
128 = 64 x 2
∛128 = ∛64 x ∛2 = 4∛2
So x = -4∛2
17. x² = 300
=> x = ± √300
300 = 100 x 3
√300 = √100 x √3 = 10√3
x = ± 10√3
18. x² = 240
x = ±√240
240 = 16 x 15
√240 = ± (√16 x √15)

For every 500 g of reactants, 3.1 g of catalyst were required. How much catalyst was
required for 900 g of reactants?
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
What do you mean by a catalyst?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
900g of reactants = [tex]\frac{3.1}{500} * 900[/tex] = 5.58g

What is algebraic identities?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
46 = m²+n²+p²

The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24
What is a tubing?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.

How to find 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.
