Answer: I think I cn help bt nt sure
Step-by-step explanation:
X° + 52° + 78° = 180°
X° + 130° = 180°
X° + 130° - 130° = 180° - 130 °
X° = 50°

a certain corner of a room is selected as the origin of a rectangular coordinate system. if a fly is crawling on an adjacent wall at a point having coordinates (1.5, 1.3), where the units are meters, what is the distance of the fly from the corner of the room?
The distance formula to get the distance of the fly from the corner of the room in meters is 1.985 meter.
Distance formula -
The distance formula is given by the equation -
[tex]d=\sqrt{ (x2-x1)^{2} +(y2-y1)^{2} \\[/tex]
[tex]where , (x_1, x_2)[/tex] and [tex](y_1,y_2)[/tex] are two given points.
Apply the distance formula to get the distance of the fly from the corner of the room in meters.
Now,
[tex]x_1 ,y_1[/tex] are form the origin,
Given:
[tex](x_2,y_2) =(1.5,1.3)[/tex]
By using the equation ,
[tex]d=\sqrt{ (x2-x1)^{2} +(y2-y1)^{2} \\[/tex]
[tex]\\d = \sqrt[2]{(1.5^{2} -0^{2})+ (1.3^{2}-0^{2} ) }[/tex]
[tex]d=\sqrt{(2.25+1.69)\\\\d=\sqrt{\frac{225}{100} +\frac{169}{100} } \\d=\sqrt{\frac{394}{100} } \\d=\frac{\sqrt{394} }{10} \\\\[/tex]
Root value of 394,
[tex]\sqrt{394}[/tex] = 19.85
[tex]d= \frac{19.85}{10} \\\\d=1.985[/tex] metre.
Therefore, the distance formula to get the distance of the fly from the corner of the room in meters is 1.985

Step-by-step explanation:
A coffee machine dispenses 8-ounce cups of coffee automatically. the amount of coffee may vary by 3%. what are the least and greatest number of ounces the coffee machine may dispense?
If a coffee machine dispenses 8-ounce cups of coffee automatically. and the amount of coffee may vary by 3% then the least and greatest number of ounces the coffee machine may dispense is 7.76 and 8.24 respectively.
The least and greatest number of ounces the coffee machine may dispense can be calculated by converting the percentage given.
As, 3% = 3 / 100
3% of 8 = 3 / 100 × 8 = 24 / 100 = 0.24
Now by adding and subtracting the calculated value to 8, the least and greatest number of ounces can be determined.
8 - 0.24 = 7.76
8 + 0.24 = 8.24
Hence, the least ounces the coffee machine may dispense is equal to 7.76 and the greatest number of ounces the coffee machine may dispense is calculated to be 8.24 ounces.

In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Find the length of u, to the nearest 10th of an inch.
Answer:
5.7
Step-by-step explanation:
Delta math
In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Hence, the length of u is 5.54 inches.
What is a cosine law?Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.
u² = s² + t² - 2(s)(t)·cos U
Given that the ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°.
We can find the length of u by using the Cosine rule
u² = s² + t² - 2(s)(t)·cos U
u² = 4.6² + 1.8² - 2(4.6)(1.8)·cos 118
u² = 19.78 + 3.24 - 16.56 x cos U
u² = 19.78 + 3.24 + 7.77
u² = 30.79
u = 5.54
Hence, the length of u is 5.54 inches.

What is an equation of the line that passes through the point (8,-4) and is parallel to the line x-4y=12?
The equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.
Two lines with slopes m₁ and m₂ are parallel when m₁ = m₂ and perpendicular when m₁*m₂ = -1.
In the question, we are asked for the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12.
The given line can be shown as:
x - 4y = 12,
or, - 4y = - x + 12,
or, y = x/4 - 12/4,
or, y = x/4 - 3.
Comparing it to the slope-intercept form of a line, y = mx + b, we get the slope, m = 1/4.
The line parallel to this will also have the slope, m = 1/4.
The required line passes through the point (8, -4).
Using the one-point formula, (y - y₁) = m(x - x₁), we can write the required equation as:
y - (-4) = (1/4)(x - 8),
or, y + 4 = x/4 - 2,
or, y = x/4 + 2,
or, x/4 - y = -2,
or, x - 4y = - 8.
Thus, the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.

Which is a unit rate?
1 Cookie/ 1/3 bag
1 Cookie/ 9 bags
2/3 cookies
3 cookies/bag
Answer:
3 cookies/bag
Step-by-step explanation:
First of all, let's define a unit rate. A unit rate is a ratio of the amount of one measurement to one unit of another measurement term. Unit rates can be expressed as fractions.
Now, here is something easier for you to remember: the second unit always have to be something with the quantity of 1.
In this case, "3 cookies/bag" shows how there are three cookies per, or in each bag--which means 1 bag. The second unit, which is bag, has the quantity of one.
Using the number line above, select the number that would be the opposite of Point T.

Segment PQ has endpoints P(-3, 4) and
Q(1, 7). Find the midpoint and length of
the segment.
-2
Mid point of the length segment PQ has endpoints P(-3, 4) and
Q(1, 7) is (1,11/2).
Mid point = {(-3+1)/2, (4+7)/2}
Mid point = (1,11/2)
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the endpoints, and it is equally distant from both of them. It cuts the section in half.
A line is said to be a bisector when it divides another line into two identical segments. The line will be split at its midpoint by the bisector. A compass and straightedge can be used to determine the midpoint of a line segment. See creating a line segment's perpendicular bisector.

m<2=1
(Please enter the number of degrees only with no words or symbols)
Answer:
m∠2= 97
Step-by-step explanation:
When 2 angles are supplementary, they add up to 180 degrees.
We are told that angle 1 is 83 and the angle 1 and 2 are supplementary
So, angle 1 and 2 add up to 180, let's subtract 83 from 180 to find measure of angle 2

If f(x) = -x + 6, find f(-3).
Find f
The value of function f when x is (-3) is 9.
To solve the value of function for the value of x as -3, we will simply keep the value of x in the equation.
Rewriting the equation
f(x) = -x + 6
Keep the values of x in the above equation
f(x) = - (-3) + 6
Adding the two negative signs, hence, the value will be 3.
f(x) = 3 + 6
Performing addition to find the value of f(x) when value of x is (-3)
f(x) = 9
Therefore, the value of f(x) is 9.

Matthew is planning a graduation party at a restaurant. Restaurant A charges $250 to reserve the room and $15 per person to eat. Restaurant B charges $370 to rent the room and $13.50 for each person to eat. How many people would Matthew need to invite for the cost at either restaurant to be the same?
Fill in the blanks to create an equation to represent the situation.
___x + 250 = 13.50x + ____
Considering the definition of an equation and the way to solve it, Matthew would need to invite 80 people.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.Number of invitesBeing "x" the number of invites, and knowing that:
Restaurant A charges $250 to reserve the room and $15 per person to eat. → Cost restaurant A= 250 + 15xRestaurant B charges $370 to rent the room and $13.50 for each person to eat. → Cost restaurant B= 370 + 13.50xIf cost at either restaurant is the same, the equation in this case is:
Cost restaurant A= Cost restaurant B
250 + 15x= 370 + 13.50x
Solving:
15x + 13.50x= 370 - 250
1.50x= 120
x= 120 ÷ 1.50
x=80
Finally, Matthew would need to invite 80 people.
