Answer:
The correct answere would be 19 degrees after solving for the length of the wire plus the diagnal of the ground.
Step-by-step explanation:
find the value of x.
Answer:
139 degrees
Step-by-step explanation:
we only have a central angle here (angle at the center of the circle).
and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).
so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees
Here is a picture of three towers.
Not all the cubes can be seen in the towers.
Edith uses 1 cube to build tower 1.
Edith uses 6 cubes to build tower 2. There are 5 cubes on the bottom layer.
The sequence below shows the number of cubes used for the bottom layer of each tower.
Answer:
nth term = the previous number times 4(x-1)
Step-by-step explanation:
As you see the first tower has 1 then it is 5 for the next tower and then it is 13 for the next tower and then 25. Well this means that as you see, the expressions adds 4 to the previous 4 and then adds to the tower. Let me show you how it works.
Tower 1: 1
Tower 2: 1 + 4 = 5
tower 3 : 5 + 8 = 13
tower 4: 13 + 12 = 25
tower 5: 25 +16 = 41
a rectangle is 12 feet long and 5 feet wide. if the length of the rectangle is increased by 25% and the width is decreased by 20% what is the change in the area of the rectangle
Answer:
60% decrease in area
Step-by-step explanation:
12 x5 == 60 sq feet (original area)
9 x 4 == 36 sq feet (new area)
36/60 = 6/10 = 60%

Find the surface area
Answer:
352 m
Step-by-step explanation:
The area of a trapeze is (the biggest base + the smallest base) × height / 2
The area from rectangles are side a × side b
Trapeze: (6+12)×4/2 = 36
Rectangles: 5 × 10 = 50
6 × 10 = 60
12 × 10 = 120
There are two trapeze andtwo rectangles with the samesize, so you double their area:
2×36 + 2 × 50 + 60 + 120 = 352 m

Solve the following inequality. 21 ≤ -3(x − 4) < 30 A. 28 ≤ x < 37 B. -10 < x ≤ -3 C. -6 < x ≤ -3 D. -3 ≤ x < 6
Step-by-step explanation:
21 ≤ -3(x − 4) < 30
=> devided by (-3)
-7 ≥ x-4 > -10
=> added by 4
-3 ≥ x > -6
the result : -6 < x ≤ -3 (option C)

Darius is studying the relationship between mathematics and art. He asks friends to each draw a "typical” rectangle. He measures the length and width in centimeters of each rectangle and plots the points on a graph, where x represents the width and y represents the length. The points representing the rectangles are (6.1, 12.0), (5.0, 8.1), (9.1, 15.2), (6.5, 10.2), (7.4, 11.3), and (10.9, 17.5). Which equation could Darius use to determine the length, in centimeters, of a "typical” rectangle for a given width in centimeters?

The product of x and 8 is not less than 16
Answer:
x ≥ 2
Step-by-step explanation:
The inequality would be: x * 8 ≥ 16
8x ≥ 16
x ≥ 16/8
x ≥ 2
Hope this helps!
Answer:
x*8 > 16
Step-by-step explanation:
product means multiplaction and x and 8 are being multiplied so x*8 and the answer is not less than or at least 16

Mr. Kevin pays $37.95 per month for his cell phone with unlimited minutes. At this rate, what will his cellphone
cost for the year
Answer:
$455.4 For The Year
Step-by-step explanation:
Kevin pays $ 37.95 per month for his cell phone with unlimited minutes
First, We know that there are 12 months in 1 year.
Therefore, 1 year = 12 months
The cost per month = $ 37.95
So, have to find the cost for 12 months
Cost for 12 months = 12 x 37.95
Cost for 12 months = 455.4
So your solution to the problem is $455.4 Cost for the year.
Los números 0, 4, -2, -1 ordenados de mayor a menor 4, .1, -.2 ,0 4, 0 -2, -1 .1,.2,0, 4 4, 0, -1, -2
Answer:
opción D
Step-by-step explanation:
El número más bajo es -2
Número mayor que -2 es -1
Número mayor que -1 es 0
Número mayor que 0 es 4
Entonces, el orden de mayor a menor es 4> 0> -1> -2
Por tanto, la opción D es correcta

Answer:
The probability is 1/41664.
To calculate the probability, write a fraction. The numerator is the number of ways the outcome can occur. The denominator is the number of different outcomes.
Thus, 1 is the number of outcomes we want. 41664 is the total number of different combinations possible.
Solve the equation to find where the treste ground levelEnter your answers from least to greatest and round to the nearest The meets the ground at and
Answer:
The trestle meets ground level at 0.875 units and 9.125 units
Step-by-step explanation:
Poorly formatted question.
The given equation is:
[tex]y = -x^2 + 10x - 8[/tex]
Required
The point where the trestle gets to the ground level
To do this, we set [tex]y = 0[/tex]
So, we have:
[tex]-x^2 + 10x - 8 = 0[/tex]
Multiply through by -1
[tex]x^2 -10x + 8 = 0[/tex]
Solve using quadratic formula:
[tex]x= \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where:
[tex]a = 1; b =-10; c = 8[/tex]
So, we have:
[tex]x= \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*8}}{2*1}[/tex]
[tex]x= \frac{-(-10) \± \sqrt{68}}{2*1}[/tex]
[tex]x= \frac{-(-10) \± 8.25}{2}[/tex]
[tex]x= \frac{10 \± 8.25}{2}[/tex]
Solve the fraction
[tex]x= 5 \± 4.125[/tex]
Split
[tex]x= 5 + 4.125\ or\ x= 5 - 4.125[/tex]
[tex]x= 9.125\ or\ x= 0.875[/tex]
