Answer:
Please check the explanation.
Step-by-step explanation:
Let suppose we have a point P(x, y) if we rotate our point 90 degrees counterclockwise about the origin, the new coordinates of the image of the point P can be obtained by switching 'x' and 'y' and making 'y' negative.
In other words,
P(x, y) → P'(-y, x)
From the given triangle ΔRST,
The coordinates of the point S is:
According to the rule, if we have a point S(10, 1), after rotations of 90 degrees counterclockwise about the origin, the new coordinates of the image of the point S(10, 1) will be:
S(10, 1) → S'(-1, 10)
Here,
S'(-1, 10) is the image of the original point or pre-image point S(10, 1).
Therefore, the y-coordinate of the point S' is: 10
Answer:
17.85 feet.
Step-by-step explanation:
Area = 1/4 * 3.14 * r^2 where r is the radius
So r^2 = 19.625 / (1/4 * 3.14)
r^2 = 25
r = 5 feet.
The perimeter = 2r + 1/4 * 2* 3.14*r
= 2*5 + 7.85
= 17.85 feet.
Answer:
4 has value of 10,000 which ten thousand place value.
Step-by-step explanation:
Given number 546210
We have to find the value of 4 in given number 546210.
We write the given number in value form as ,
546210 = 5×100000 + 4× 10000 + 6 ×1000 + 2×100 + 10
in words it is written as
Here, 4 has value of 10,000 which ten thousand place value.
Sarah = 53 inches
Brother = 53 + 4 = 57 inches
-----------------------------------
Convert inches to feet
-----------------------------------
57 ÷ 12 = 4 feet 9 inches
----------------------------------------------------------------------
Answer: 4 ft 9 in

Answer:
<h3>x = 5</h3>
Step-by-step explanation:
The sum of two complementary angle is 90 degrees. Given the following complementary angles;
<1 = 6x + 5
<2 = 8x + 15
<1 + <2 = 90 (complementary angles)
6x + 5 + 8x + 15 = 90
14x + 20 = 90
14x = 90-20
14x = 70
x = 70/14
x = 5
Hence the measure of x is 5
