Your answer
Answers
Answer:
15°
Step-by-step explanation:
Reference angle = [tex] \theta [/tex]
Side Opposite to reference angle = 10
Hypotenuse = 39
Let's use arcsin:
recall: SOHCAHTOA
Therefore:
[tex] \theta = sin^{-1}(\frac{Opp}{Hyp}) [/tex]
Substitute
[tex] \theta = sin^{-1}(\frac{10}{39}) [/tex]
[tex] \theta [/tex] = 14.8571655° = 15° (to nearest whole number)

The Becks buy a plastic tarp to cover their firewood. A rectangle that is eight and one-third yards long and six and three-fourths yards wide. Part A Which equation models the best estimate for the area of the tarp?
Answers
Answer:
56 1/4 yards
Step-by-step explanation:
Area of the tarp = length × width
Length = 8 1/3 yards
Width = 6 3/4 yards
Area of the tarp = length × width
= 8 1/3 yards × 6 3/4 yards
= 25/3 × 27/4
= (25 * 27) / (3 * 4)
= 675 / 12
= 56 1/4 yards
Area of the tarp = 56 1/4 yards

Answer:
13. Option 3
14.Option 2
Step-by-step explanation:
Option 3 shows that caleb has $5 or less by using the "less than or equal to" sign
Option 2 uses a closed circle to show that $5 is included in the table.
Things to remember that helped me
Closed circle are used for < and > signs to show that the number is being included. They mean "less than or equal to (<)" and "more than or equal to(>)"
Open circles are used for < and > signs. To show that the number is NOT included in the inequality.
Also when looking at the signs < and >, Picture them as arrows. That will show you the direction on the number line they go. For example < is pointing to the left which would mean "LESS THAN" and same with >, its pointing to the right which would mean "MORE THAN"

B. Rectangle ABCD has been dilated using C as the center.
C. Rectangle ABCD has been reflected using O as the center.
D. Rectangle ABCD has been dilated using O as the center
Answers
The statement is true about the shown figures "Trapezoid ABCD has been dilated using O as the center". which is the correct answer would be an option (A).
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
here, we have,
A dilation is a transformation that generates an image with the same shape as the original but a different size. The dilation center is a fixed point in the plane. The initial figure is stretched or shrunk through dilatation.
As per the given figures,
Trapezoid ABCD has been expanded to trapezoid A'B'C'D' around the dilation center O. When the figure is expanded, the scale factor exceeds one.
Thus, the statement is true about the shown figures "Trapezoid ABCD has been dilated using O as the center".
Hence, the correct answer would be option (A).

What is the value of x in the triangle?
Answers
Answer:
x=130
Step-by-step explanation:
Hello There!
Remember the sum of the angles in a triangle is 180
So we can find the missing angle by subtracting the given angles (25 and 25 in this case) from 180
so x = 180 - 25 - 25
180 - 25 = 155
155 - 25 = 130
x = 130
When looking for a job micah is told that the monthly salary has a range of 876 he also knows that the starting salary is 1,793 per month what is the maximum amount of money that micah can earn in this position?
Answers
Answer:
2669
Step-by-step explanation:
Given that :
Salary range = 876
Starting salary = 1793 monthly
The starting salary represents the minimum amount Micah can earn monthly
Therefore, the amount of money much can earn can be calculated thus :
Recall :
Range = maximum - minimum
876 = maximum - 1793
876 + 1793 = maximum
Maximum = 2669
Hence, the maximum salary Micha can earn is 2669 monthly

V = [tex]\pi* 5.8^2*\frac{15}{3}[/tex]
V ≈ 528.1
Alex records the running time—the number of minutes a movie lasts from start to finish—of 50 popular movies. The distribution of times, in minutes, is displayed in the histogram below.
Answers
Answer:
You forgot to attach the question and the histogram.
Is your question “the interval containing the most movies” ? If yes, then the answer is :
Interval 90-100 minutes
Step-by-step explanation:
A histogram is a chart that is used to represent data in form of bars.
Like every other chart, it consists of both the x and y axis. The y axis contains the frequency or percentage of occurrences while the x axis contains the range or intervals.
To determine the interval with the most occurrences, that is the interval containing most movies, we look for the bar with the most height. The bar that is tallest amongst others has the most movies in its running time.
From the attached histogram, the interval containing the most movies is the 90- 100 minutes interval.
This simply means that from Alex’s record, out of the 50 popular movies, more movies run with the 90-100 minutes interval.
PS: view the attached histogram

the answer is no.a parallelogram is not a rectangular but the opposite is true. the reason is a cause of parallelogram's diagonals.they might not be equal in parallelogram but in rectangular they must be equal.
Step-by-step explanation:
Answer:
If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. So yes it is a parallelogram.
Step-by-step explanation:
Diagonals of parallelogram are not necessarily equal. This is a known property of a parallelogram. If all angles are equal, then it means its opposite angles are also equal which is a condition for a quadrilateral to be called parallelogram. If all sides are equal then, opposite sides are also equal.
