x = -5 + 5√3
Step-by-step explanation:
A = ℓ × w
50 = (x + 10) × x
50 = x² + 10x
x² + 10x - 50 = 0
a = 1b = 10c = -50x = [-b ± √(b² - 4ac)] / 2a
x = [-10 ± √(10² - 4(1)(-50))] / 2(1)
x = [-10 ± √(100 - (-200))]/2
x = [-10 ± √300]/2
x = [-10 ± 10√3]/2
x = [-5 ± 5√3]
because x is a unit of length, it is positive
x = -5 + 5√3

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given square on the right is a scaled copy of the square on the left.
So 11 is being multiplied by something to get to 33/2
So 11x = 33/2
Solve for x:
11x = 33/2
x = 33/ 2(11)
x = 3/2

Claire's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y represented by the equation y = 56 + 7.1x, where y represents the expected quiz score and x represents hours spent on homework that week. What is the meaning of the x-value when y = 92?
the change in expected quiz for every additional one hour students spend on their homework.
a student's expected quiz score if they spent 1 hours on their homework.
the number of hours a student should spend on their homework to expect a score of 92 on the quiz.
a student's expected quiz if they spent 92 hours on their homework.
Answer: t = 5.7 hours
Step-by-step explanation:
y=56+7.1x where x is the time spent studying. If y=92, this equation would preduct that the student spent t hours studying. Find t:
92=56+7.1x
36=7.1t
t = 5.07 hours to achieve the 92 score.
Answer: The number of hours a student should spend on their homework to expect a score of 97 on the quiz

Enter an equation in point-slope form for the line.
Slope is -4 and (1,9) is on the line.
The equation of the line in point slope form is:
Answer: (y-9) = -4(x-1)
Step-by-step explanation: The format of a point-slope line is y − y1 = m(x − x1), where x1 and y1 are a known point on a line with slope m. Given slope of -4 and a point of (1,9):
(y − y1) = m(x − x1)
(y − 9) = -4(x − 1)
This can be rearranged to the standard form: y = -4x+13

$14/hr.
O
$15/hr.
$16/hr.
Answer:
$13/hr
esa es la respuesta
Answer:
$13/hr
Step-by-step explanation:
Without bonus gross income = $350 - $51 = $299
Hours combined = 6hr + 8hr + 9hr = 23hr

If you know two angle measures of a triangle in spherical geometry, can you always find the measure of the third angle? Explain.
A. Yes; the angle measures of a triangle always sum to 180.
B. Yes; the angle measures of a triangle always sum to 270 in spherical
geometry.
C. No; the sum of angle measures in spherical geometry is always greater than
180, but there is not a particular number they must sum to.
D. No; the sum of angle measures in spherical geometry is always greater than
270, but there is not a particular number they must sum to.
When two angle measure of a triangle are given in spherical geometry: The sum of angle measures in spherical geometry is always greater than 180, but there is not a particular number they must sum to. Choice C (No) is correct
According to the question;
Two angle measures of a triangle in spherical geometry are given.However, unlike in plane geometry where affirmatively, the sum of angles in a triangle is equal to 180°.
In spherical geometry;
The totality of the angles of a triangle on a sphere is given as 180°(1 + 4x), where x is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of x, which in each case exceeds 180°.

Nyesha owns a lawn service company. Currently it takes her 50 hours a week to service all of her
customers. To reduce the number of hours a week she needs to work, Nyseha hires Shantese to
help her. While Nyesha was on vacation, Shantese was able to complete all of the work in 60 hours.
If Shantese and Nyesha work together, after Nyesha returns from facation, how long will it take
them to service all their customers?
Fractions are integers that have both a numerator and a denominator. They are represented as; [tex]\frac{x}{y}[/tex]
Where:
x = Numerator
y = Denominator.
To solve the above question, we would be applying the operations of the addition of fractions.
It will take both of them [tex]27\frac{3}{11}[/tex] hours if they worked together.
From the question,
Nyesha takes 50 hours a week to render services to her customers.
Shantese takes 60 hours a week to do the same amount of work.
Let us represent the number of hours it will take them both to decorate the room working together as "T"
Hence,
1/T = 1/50 + 1/60
Lowest Common Denominator for (50, 60 ) = 300
Hence,
1/T = 6 + 5 / 300
1/T = 11/300
Find the reciprocal of both sides
T = 300/11 hours
T = [tex]27\frac{3}{11}[/tex] hours
Therefore, it will take them both of them [tex]27\frac{3}{11}[/tex] hours in they both work together.

The larger of two consecutive integers is 13 greater than four times the smaller. Find the integers. -3, -4 7, 8 3, 4
Answer:
The integers are -3 and -4.
Step-by-step explanation:
Two consecutive integers are an integer and the one just greater or just less than the4 first one, such as 5 and 6, or -8 and -9.
If the smaller integer is x, then the next greater integer is x + 1.
x + 1 = 4x + 13
-3x = 12
x = -4
x + 1 = -3
Answer: The integers are -3 and -4.
Check:
Smaller integer: -4
Larger integer: -3
4 times smaller integer = 4 * (-4) = -16
13 greater than 4 times smaller = -16 + 13 = -3 = greater integer
-3 and -4 is the correct answer.
Answer:
-3 and -4

Preliminary:
Fractions in Mathematics are rational numbers that can be written in the form x/y, where x and y are integers, and y 0 and the number x is not a multiple of y. In fractions x is called the numerator while y is called the denominator.
Fraction Types:
Common Fraction = is a fraction expressed in the form x/y, x as the numerator and y as the denominator. x and y are integers and y 0Mixed fraction = is a combination of whole numbers and fractions, expressed in the form a [tex] \frac{b}{c} [/tex]Decimal fractions are indicated by a comma (,) as a separator between the round and fractional parts. The round part is in front of the comma and the fraction part is behind it. One digit after the comma means the denominator of the fraction 10, two digits after the comma means the denominator of the fraction 100, and so on.A percent fraction is a fraction that has a denominator of 100, expressed in the form a%. example 50% is the same as [tex] \frac{50}{100} [/tex]Answer:

Lines AB and CD are perpendicular to each other. If 3 measures (5x + 2)°, and 4 measures 13°, what is the value of x?
A.
x = 15
B.
x = 77
C.
x = 2
D.
x = 21
Answer:
A is the correct option.
Step-by-step explanation:
Since both lines are perpendicular to each other, that means the sum of their angles is equal to 90°.
Then,
(5x + 2) ° + 13° = 90°
5x + 15° = 90°
5x = 75°
x = 15°

In this lesson you discovered the Angle Blsector Conjecture. Write the converse of the Angle Blsector Conjecture. Do you think it's true. Why or why not?
Answer: The converse is that if a point is on the interior of an angle and is equidistant from both sides of the angle, then the point lies on the angle bisector. This makes sense since the distance from a point and a side of the angle is a perpendicular line connecting the point to a side. And since it is equidistant from both sides, the perpendicular lines have to be congruent, it make sense if the point is on the angle bisector, the traingles would be congruent.
Step-by-step explanation: The explanation is in the answer.
