A sign on the road says " Speed limit, 60 miles per hour. Let s be the speed of car.Write an inequality that matches the information on the sign
Answer: s ≤ 60
Step-by-step explanation:
The common inequality signs include:
> which is greater than
< which is less than
= which is equal to
≥ which is greater than or equal to
≤ which is less than or equal to
Since the speed limit is 60 miles per hour, it simply means that the speed limit is less than or equal to 60 miles per hour. This will be:
s ≤ 60
The above means the speed is less than or equal to 60 miles per hour

Answer:
Perimeter [tex]\sqrt{26}+\sqrt{5}+\sqrt{10}+\sqrt{17}[/tex] units. Area 12 square units.
Step-by-step explanation:
Perimeter: total distance around the figure.
Distance Formula: the distance between points [tex]\left(x_1,y_1\right) \text{ and } \left(x_2,y_2\right)[/tex] is
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]AB=\sqrt{(6-1)^2+(2-1)^2}=\sqrt{25+1}=\sqrt{26}[/tex]
[tex]BC=\sqrt{(5-6)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5}[/tex][tex]CD=\sqrt{(2-5)^2+(5-4)^2}=\sqrt{9+1}=\sqrt{10}[/tex][tex]DA=\sqrt{(1-2)^2+(1-5)^2}=\sqrt{1+16}=\sqrt{17}[/tex]
The perimeter is the sum of all those segment lengths.
One way to find the area of the figure is to surround it with a rectangle, insert some lines so that the areas you do not want can be found and subtracted from the rectangle's area. (See attached image.)
The area of the large rectangle around the figure is 5 x 4 = 20 square units.
The triangles have areas 1/2 (base) (height):
A. (1/2)(1)(4) = 2 square units
B. (1/2)(3)(1) = 1.5 square units
D. (1/2)(1)(2) = 1 square unit
E. (1/2)(5)(1) = 2.5 square units
Square C. (1)(1) = 1 square unit
Total of all the area you don't want to include:
2 + 1.5 + 1 + 2.5 + 1 = 8 square units
Subtract 8 from the surrounding rectangle's area of 20, and you get the area of the figure is 20 - 8 = 12 square units.

Answer:
a. east
b. 60 feet per second
Step-by-step explanation:
did this a while ago.
a. -180 is east, 120 is east. the car is traveling east because it is moving positive. read the last sentence of the description.
b. to calculate velocity you do time times position. in this case position is 60 and time is 1 so 60*1 is 60. so it is 60 feet per second.
The graph of the equation y = 4x + 8 is shown. Which TWO statements are correct?
es )
A)
The coordinate pair (0, 10) represents a point on the graph and a solution
to the equation.
B)
The coordinate pair (-1, 4) represents a point on the graph and a solution
to the equation.
0
The coordinate pair (-2, 1) represents a point on the graph and a solution
to the equation.
D)
The coordinate pair (-3, 2) represents a point on the graph and a solution
to the equation
E)
The coordinate pair (-4,-8) represents a point on the graph and a solution
to the equation.
The correct statements are:
- The coordinate pair (-2, 1) represents a point on the graph and a solution to the equation.
-The coordinate pair (-4, -8) represents a point on the graph and a solution to the equation.
Options C and E are the correct answer.
We have,
The equation y = 4x + 8 represents a linear relationship between x and y.
To determine which statements are correct, we need to substitute the x-coordinate of each given coordinate pair into the equation and see if it satisfies the equation.
A) The coordinate pair (0, 10)
Substituting x = 0 into the equation: y = 4(0) + 8 = 8
So, (0, 10) does not satisfy the equation.
Statement A is incorrect.
B) The coordinate pair (-1, 4)
Substituting x = -1 into the equation: y = 4(-1) + 8 = 4 + 8 = 12
So, (−1, 4) does not satisfy the equation.
Statement B is incorrect.
C) The coordinate pair (-2, 1)
Substituting x = -2 into the equation: y = 4(-2) + 8 = -8 + 8 = 0
So, (−2, 1) does satisfy the equation.
Statement C is correct.
D) The coordinate pair (-3, 2)
Substituting x = -3 into the equation: y = 4(-3) + 8 = -12 + 8 = -4
So, (−3, 2) does not satisfy the equation.
Statement D is incorrect.
E) The coordinate pair (-4, -8)
Substituting x = -4 into the equation: y = 4(-4) + 8 = -16 + 8 = -8
So, (−4, -8) does satisfy the equation.
Statement E is correct.
Therefore,
The correct statements are:
- The coordinate pair (-2, 1) represents a point on the graph and a solution to the equation.
-The coordinate pair (-4, -8) represents a point on the graph and a solution to the equation.

4x = 2(x-5)-2 can you solve please
Answer:
x = -6
Step-by-step explanation:
4x = 2(x-5)-2
2 * x = 2x
2*-5 = -10
4x = 2x - 10 -2
4x = 2x - 12
4x - 2x = 2x
2x = -12
-12/2 = -6
x = -6

Given an arithmetic sequence described by the formula a= -2(n - 1) + 7 find a^28
Answer:
-47
Step-by-step explanation:
Given the arithmetic sequence described by the formula;
a= -2(n - 1) + 7
To get a28, we will substitute n = 28 into the expression
a28 = -2(28-1)+7
a28 = -2(27)+7
a28 = -54+7
a28 = -47
Hence a28 is -47

If your initial principal is $243 and your principal in 2 years is $1,359.19, how much interest did you earn?
Answer: $1,116.19
Step-by-step explanation:
If you invested $243 and this increased to $1,359.19 in two years, the difference between your investment and its current worth is the interest:
= Current principal - Initial principal
= 1,359.19 - 243
= $1,116.19
