round 5495 to the nearest 1000
Answer:
5000
Step-by-step explanation:
less than 500 so it goes to the closest 1000 under the number
Rounding off the given value 5495 ( five thousand four hundred and ninety four ) to the nearest one thousand is 5000 ( five thousand ).
What is Rounding numbers?Rounding simply means making a number easier or simpler but keeping its value close to its previous value. This might be less accurate, but easier to read.
To round 5495 to the nearest 1000.
Rounding off to the nearest thousand, if the digit in the hundreds place is between 0 and 4 then the hundreds place is replaced by ‘0’.If the digit in the hundreds place is 5 or greater, then the hundreds place is replaced by ‘0' and the thousands place is increased by 1.5495 to the nearest 1000 will be 5000.
Hence, rounding the given value 5495 ( five thousand four hundred and ninety four ) to the nearest one thousand is 5000 ( five thousand ).

Answer:
EH = 16
Perimeter = 46
Step-by-step explanation:
We see that the ratio between the big shape and small shape is 3:2. 3x=24, so x=8. EH=2x=16.
For the second problem, the perimeter is 46.
This is because it also follows the same rule as 3:2. If you do this for every side, you find out that the sides are 10, 10, 6, 12, and 8. Add them together to get 46.

an inscribed angle is half the measure of the arc it interceptsthe sum of arcs of a circle is 360°the measure of a central angle is the same as the measure of the arc it intercepts.__
The long arc intercepted by the inscribed 130° angle will measure 2×130° = 260°. The sum of arcs of a circle is 360°, so the short arc intercepted by the 130° angle (and by x°) is ...
x° = 360° -260° = 100°
The measure of angle x is 100°.

:))
Answer:
-1Step-by-step explanation:
Given
7x + 3y = 9We need to evaluate :
7x + 3y - 10We already know the value of 7x + 3y, so substitute its value in the given equation and solve.
7x + 3y - 109 - 10-1Find the x-intercept of a line that has the following equation: 2y=3x−6
Answer:
2
Step-by-step explanation:
To find the x-intercept of the equation we have to substitute y = 0 in it.
=> 0 = 3x - 6
=> 3x = 6
=> x = 2
Therefore the line will meet x-axis at (2,0) which means it'll have x - intercept of 2 units.
Rotate RST 90 degrees counterclockwise around the origin
Step-by-step explanation:
Unfortunately, you haven't given the coordinates of RST so I can't tell you exactly what the new points will be, but I can tell you what process to follow.
To find a new point rotated 90 degrees counterclockwise around the origin, simply apply the rule:
(x,y) ----> (-y,x)
You would apply this rule of switching the x and y coordinates and y becomes the opposite(so if it was a positive coordinate, it becomes negative and if it was negative, it becomes positive), to get your new coordinates.

What is the measure of angle 3 if the measure of
angle 6 is 4x + 10 and the measure of angle 7 is 2x + 40?
Answer:
Angle 3 = 86.8
Angle 6 = 96.4
Angle 7 = 93.2
Step-by-step explanation:
Given :
angle 6 = 4x + 10
angle 7 = 2x + 40
=> angle 6 + angle 7 = 180° { linear pair }
=> 4x+10 +2x+40 = 180
=> 6x+50 = 180
=> 6x = 180-50
=> 6x = 130
=> x = 130/6
=> x = 21.6
so ,the measure of angle 6 = 4x + 10 = 4(21.6) +10 = 86.4+10 = 96.4
the measure of angle 7 = 2x + 40 = 2(21.6) +40 = 43.2+50 = 93.2
now angle 7 = angle 4 + angle 5
and angle 3 + angle 4 + angle 5 = 180°
so, angle 7 + angle 3 = 180
=> 93.2 + angle 3 = 180
=> angle 3 = 180 - 93.2
=> angle 3 = 86.8
