Answer: 150 degrees
Step-by-step explanation:
The number of degrees did it rotate altogether should be considered as the 150 degrees.
Calculation of the number of degrees:Since A sprinkler rotates 75°, pauses, and then rotates another 75
So, here total degrees be like
= 75 degrees + 75 degrees
= 150 degrees
hence, The number of degrees did it rotate altogether should be considered as the 150 degrees.

Which of the following represents the general equation for the geometric sequence?
-1, -2, -4, …
a n = 2 n - 1
a n = -1 · 2 n - 1
a n = 1 · 2 n + 1
a n = 1 · 2 n - 1
Answer:
-1,-2,-4
an = a1 * r^(n - 1)
a1 = first term = -1
r = common ratio = 2
so the equation would be : an = -1 * 2^(n - 1)
Markus buys an old bike for £50. He cleans it up and sells it for £60. What is his percentage profit?
An antique desk,that once belonged to President Kennedy, appreciates in value by 15% per year. If Mark Zuckerberg were to purchase the desk for $50,000,how much would it be worth from now?
Answer:
$57500
Step-by-step explanation:
Given data
Initial cost of desk= $50,000
Percent increase=15%
=15/100*50,000
=0.15*50,000
=$7500
Hence the new price is 7500+50,000
=$57500
If my diameter is 35.64 what is my circumference
Answer:
55.9548
Step-by-step explanation:
35.64 ÷ 2 = 17.82
17.82 × 3.14 = 55.9548
Answer: 111.97
Step-by-step explanation:
Circumference of a circle= 2πr
r= d/2
diameter= 35.64
Therefore circumference= 2*(3.14)*(35.64/2)
= 111.97
Naomi and Hudson work at a dry cleaners ironing shirts. Naomi can iron 35 shirts per hour, and Hudson can iron 20 shirts per hour. Naomi and Hudson worked a combined 13 hours and ironed 395 shirts. Write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked. Define the variables that you use to write the system.
Answer:
Given that Naomi and Hudson work at a dry cleaners ironing shirts, and Naomi can iron 35 shirts per hour, while Hudson can iron 20 shirts per hour, knowing that Naomi and Hudson worked a combined 13 hours and ironed 395 shirts, to write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked, the following logical reasoning should be performed:
Naomi, working 13 hours, can iron up to 455 shirts (13 x 35), with which, every hour that Hudson has worked and she does not imply a decrease of 15 ironed shirts. Since 455 - 395 equals 60, and 60/20 equals 3, it is determined that Hudson worked 3 hours, while Naomi worked 10 hours.
Thus, the proposed inequality would be the following:
35Y + 20X = 395

The deck that Amos is building is in the shape of a parallelogram, DGRY. The measure of
Complete Question:
The deck that Amos is building is in the shape of a parallelogram, DGRY. The measure of D is five-halves the measure of Y. Find the measure of each angle of the deck.
Answer:
[tex]\angle G = \angle Y = 51.43 ^{\circ}[/tex]
[tex]\angle D = \angle R = 128.57 ^{\circ}[/tex]
Step-by-step explanation:
Given
Shape: Parallelogram DGRY
Dimension: [tex]\angle D = \frac{5}{2}\angle Y[/tex]
Required
Find the measure of each angle
D and R are opposite sides & G and Y are also opposite sides.
So, we have:
[tex]\angle D = \angle R = \frac{5}{2}\angle Y[/tex]
and
[tex]\angle G = \angle Y[/tex]
The sum of angles is given as:
[tex]\angle D + \angle G + \angle R + \angle Y=360^{\circ}[/tex]
Substitute values for [tex]\angle D, \angle G \ \& \angle R[/tex]
[tex]\frac{5}{2}\angle Y + \frac{5}{2}\angle Y + \angle Y + \angle Y = 360^{\circ}[/tex]
Take LCM
[tex]\frac{5\angle Y + 5\angle Y + 2\angle Y+ 2\angle Y}{2}= 360^{\circ}[/tex]
[tex]\frac{14\angle Y}{2}= 360^{\circ}[/tex]
Multiply both sides by [tex]\frac{2}{14}[/tex]
[tex]\frac{2}{14} * \frac{14\angle Y}{2}= 360^{\circ} * \frac{2}{14}[/tex]
[tex]\angle Y= 360^{\circ} * \frac{2}{14}[/tex]
[tex]\angle Y= \frac{ 360^{\circ} *2}{14}[/tex]
[tex]\angle Y= \frac{720^{\circ}}{14}[/tex]
[tex]\angle Y= 51.43 ^{\circ}[/tex]
So:
[tex]\angle G = \angle Y = 51.43 ^{\circ}[/tex]
[tex]\angle D = \frac{5}{2}\angle Y[/tex]
[tex]\angle D = \frac{5}{2} * 51.43^{\circ}[/tex]
[tex]\angle D = \frac{5* 51.43^{\circ}}{2}[/tex]
[tex]\angle D = \frac{257.15^{\circ}}{2}[/tex]
[tex]\angle D = 128.57 ^{\circ}[/tex]
Hence:
[tex]\angle D = \angle R = 128.57 ^{\circ}[/tex]
From the set {7.8, 8.5, 9.1, 9.9}, use substitution to determine which value of x makes the equation true. 3.2 (x - 6.7) = 5.76
Answer:
8.5
Step-by-step explanation:
Given the equation :
3.2(x - 6.7) = 5.76
x - 6.7 = 5.76 / 3.2
x - 6.7 = 1.8
x = 1.8 + 6.7
x = 8.5

1.How will you determine the center and radius given the equation of the circle
in standard form? in general form?
2.How will you determine the equation of the circle given the center and radius ?
Answer:
Step-by-step explanation:
Circle Standard Form
The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.
