Answer:
x = 15.4
Step-by-step explanation:
Tan 33 = [tex]\frac{opposite }{adjacent}[/tex]
Where opposite = 10, adjacent = x
=> 0.649 = 10/x
=> x = 10/0.649
=> x = 15.4

▹ Answer
The correct answer is C. x = 375 sq ft y = 6,300 sq ft
▹ Step-by-Step Explanation
The ratio is 1:15 so...
x → 5,625
(Divide 5,625 by 15 since we have to find the x value meaning we have to do the inverse operation)
5,625 ÷ 15 = 375
420 → y
(Multiply 420 by 15 since we have to find the y value meaning we have to do multiplication)
420 × 15 = 6,300

Answer:
x° = 62
Step-by-step explanation:
The vertical angle to 28 degrees is 28 degrees in size.
The vertical angle to 90 degrees is 90 degrees in size.
Angles in a circle add up to 360 degrees.
x + 28 + 152 + 28 + 90 = 360
x + 298 = 360
x = 360 - 298
x = 62
Angle x is 62 degrees in size.

Step-by-step explanation:
A motor powers a model car so that after starting
from rest, the car travels s inches in t seconds,
where s = 16t\t. Which of the following gives the
average speed of the car, in inches per second, over
the first t seconds after it starts?
Answers
Answer:
B) 16√t
Average speed of the car =16√t inches per second
Step-by-step explanation:
A) 4√t
B) 16√t
C) 16 / √t
D) 16t
Speed = distance / time
Distance = 16t√t
Time = t
Substitute the value of distance and time into the formula
Speed = distance / time
Speed = 16t√t / t
= 16√t
Therefore, speed = 16√t
Average speed of the car =16√t inches per second

You decide to simulate the survey by having your computer randomly list values 1 through 31. Would the simulation provide a fair representation of an actual survey of 100 people? Why or why not?
No, because for the 12 months in the year not all of the dates are represented.
Yes, because it is possible to get 100 random values in a simulation.
Yes, because all possible dates of the month would be represented.
No, because for the 12 months in the year each date is not equally likely.

PLZ HELP, NEED ASAP Krista was assigned a homework problem that stated there were 45 stamps purchased for $18.75. Some stamps were 40 cents, and some stamps were 55 cents. To solve this problem, she wrote the system of equations that is shown below. 0.40 x + y = 45. x + 0.55 y = 18.75. Which explains the error that Krista made? Krista put 0.40 in the first equation meant for the number of stamps. Krista put 0.55 in the second equation meant for the value of stamps. Krista did not use the correct decimal to represent the total cost of the stamps. Krista mistakenly put 45 in the first equation when it should have been in the second equation.
Answers
Answer:
Krista put 0.40 in the first equation meant for the number of stamps.
Step-by-step explanation:
Krista's equation
0.40x+y=45
x+0.55y=18.75
The system of Equation should have been
x + y = 45 (1)
0.40x + 0.55y = 18.75 (2)
From (1)
x=45-y
Substitute x=45-y into (2)
0.40(45 - y) + 0.55y = 18.75
18 - 0.40y + 0.55y = 18.75
Collect like terms and you now have
0.55y - 0.40y = 18.75 - 18
0.15y = 0.75
Divide both sides of the equation by 0.15
y = 5
Substitute y=5 into (1)
x + y = 45
x+5=45
x=45-5
x=40
This shows that the stamps that cost 0.40 cents were 40 while those that cost 0.55 cents were 5 in number.
Krista's error:
Krista put 0.40 in the first equation meant for the number of stamps.
Answer: A, Krista put 0.40 in the first equation meant for the number of stamps.

8. In the diagram below, angle CAE = 39 °. Find the following
:) AOC
b) OBA
Answers
Answer:
a) 78°
b) 39°
Step-by-step explanation:
In circle with center O, DE is tangent at point A and AC is chord (or secant if extended both sides).
Therefore by tangent secant theorem.
[tex] m\angle CAE = \frac{1}{2} \times m\widehat{(AC)} \\\\
\therefore 39\degree = \frac{1}{2} \times m\widehat{(AC)} \\\\
\therefore m\widehat{(AC)} = 39\degree\times 2\\
\red{\bold{\therefore m\widehat{(AC)} = 78\degree}}\\[/tex]
Since, measure of central angle of a circle is equal to the measure of its corresponding minor arc.
[tex] \therefore m\angle AOC = m\widehat{(AC)}\\
\huge \purple {\boxed {\therefore m\angle AOC = 78\degree}} \\[/tex]
Next, by inscribed angle theorem:
[tex] m\angle CBA = \frac{1}{2}\times m\widehat{(AC)}\\\\
\therefore m\angle CBA = \frac{1}{2}\times 78\degree \\\\
\therefore m\angle CBA =39\degree \\\\
\huge \orange{\boxed {\therefore m\angle OBA = 39\degree}}\\... (\because C-O-B) \\[/tex]

In a linear relationship:
variable a / variable b = k
Case: side length and perimeter of 1 face
12/3 = 16/4 = 20/5 = 24/6 = 4
Case: perimeter of 1 face and area of 1 face
12/9 ≠ 16/16 ≠ 20/25 ≠ 24/36
Case: surface area and volume
54/27 ≠ 96/64 ≠ 150/125 ≠ 216/216
Case: area of 1 face and surface area
54/9 = 96/16 = 150/25 = 216/36 = 6
Case: side length and volume
27/3 ≠ 64/4 ≠ 125/5 ≠ 216/6
The side length and the perimeter of one face have a linear relationship.

Answers
Answer:
The correct options are:
(8,4)
(16,8)
Step-by-step explanation:
The table is given which shows the number of yellow tiles and red tiles.
The first row in the table shows that if there are 4 red tiles then there will be 2 yellow tiles. This relation can be defined as the number of red tile will always be double the amount of number of yellows tiles. Carter graphs this point as (4,2) where number of red tiles are plotted on x axis and number of yellow tile are plotted on y axis.
Consider the second row of the table. Number of red tiles is 8 while number of yellow tiles is 4, so the point he plots on the graph is (8,4)
Similarly, other points are (12,6) and (16,8)
