A 13 km stretch of road needs repairs. Workers can repair 3 1/2km of road per week.
How many weeks will it take to repair this stretch of road?
The workers would need 3.71 weeks to repair the road.
A generalization of arithmetic in which letters representing numbers are combined using arithmetic rules
Given that the total length of the road is 13km. Workers can repair 3.50 roads per week.
To determine the number of weeks required to repair the road, divide the total by per week. The equation would be:
13 ÷ 3.5
= (13 x 10)/35
= 130/ 35
= 3.71
Therefore the workers would need 3.71 weeks to repair the road.

Consider the diagram shown. what is the angle of x
By using angles properties (sum of interior angles of a triangle and so) we will see that the measure of angle x is 120°.
How to get the value of angle x?Let's define C as the angle inside the triangle that is adjacent to angle x.
We can see that these two are supplementary angles, then we know that:
C + x = 180°.
We also can see that C is an interior angle of a triangle, and remember that the sum of all interior angles of a triangle is equal to 180°, then we can write
68° + 52° + C = 180°
With that equation, we can find the value of C.
C = 180° - 52° - 68° = 60°
Then.
x + C = 180°
x + 60° = 180°
x = 180° - 60° = 120°
That is the measure of angle x.

The bank is offering a simple interes rate
r = 1.9%
a) how much interes will the customer earn in 10 years
A = P(1 + rt)
t = 10 years
Calculation:
First, converting R percent to r a decimal
r = R/100 = 1.9%/100 = 0.019 per year.
Solving our equation:
A = 5000(1 + (0.019 × 10)) = 5950
A = $5,950.00
I = A - P = $950.00
b) After 10 years the account balance will be

An irrigation system (sprinkler) has a parabolic pattern. The height, in feet, of the spray of water is given by the equation h(x)=−x2+10x+9.5, where x is the number of feet away from the sprinkler head (along the ground) the spray is.
The irrigation system is positioned 9.5 feet
The spray reaches a maximum height of 34.5 feet
The spray reaches all the way to the ground at about 10.87 feet
How to find the maximum height of the spray
The standard form of a quadratic equation is given by the formula
y = ax^2 + bx + c
compared with the given equation h(x) = −x^2 + 10x + 9.5 the solutions are calculated as follows
The irrigation position refers to the value of h(x) at x = 0
h(x) = −x^2 + 10x + 9.5
h(0) = 0^2 + 10*0 + 9.5
= 9.5
The maximum height is at the symmetry of the parabolic curve, for a curve opening downward.
At the symmetry x = -b/2a
x = -b/2a = -10/(2 * -1) = 5, At x = 5, then y is
h(5) = −(5)^2 + 10 * 5 + 9.5 = 34.5
The maximum horizontal distance is at one of the roots solved as
h(x) = −x^2 + 10x + 9.5
x = 10.87 OR -0.87
The maximum distance is the greatest distance form the origin (0, 0). Therefore maximum distance is at x = 10.87 feet

Step-by-step explanation:
You could think of ratios as fractions :
Whatever we do to the top we must do to the bottom to keep it equivalent .
If we multiply the first thing by something we must do the multiply by the same number to the second.
2 × m = 8
m = 4
3 × m = ?
m = 4
3 × 4 = 12
? = 12
So the number that makes the ratio equivalent is 12

What is the equation of circle?Given the circle's center and radius, the equation of a circle offers an algebraic approach to describe a circle. The formulas used to determine a circle's area or circumference are different from the equation for a circle. Numerous coordinate geometry problems involving circles employ this equation.We need the equation of the circle in order to represent a circle on the Cartesian plane. If we are aware of a circle's center and radius, we can draw it on a piece of paper.

What is defined as the equivalent expressions?
Expressions that function identically despite having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then when we enter the same value(s) for the variable, the two expressions have the same value.Each float advances by 5 units.
Each group takes a two-unit step.
As a result, the submarine's final position is:
Final = -(5)(3) - (2)(4)
The minus "-" symbol indicates that the submarine is sinking.
