The number of hours Nick took to reach the shopping mall in terms of r  is ; 3.14  hours.

Rate is a measure of a quantity using another quantity as the basis.

Analysis:

speed travelling on foot = r

distance travelled on foot = 5 miles

time taken = 5/r

speed travelling on bicycle 80 percent faster than on foot is 1.8r

distance travelled on bicycle = 8 miles

time taken = 8/1.8r = 40/9r

total time taken to get to the mall = 5/r + 40/9r = 85/9r

speed while walking = 3 miles per hour = r

time taken = 85/9 x 3 = 3.14 hours

In conclusion, number of hours Nick took to reach the shopping mall in terms of r is 85/9r is 3.14  hours.

Find two points in order to calculate slope:

Slope (m) =

ΔY /ΔX= -1/ 3= -0.33333333333333

Slope intercept:

y = -0.33333333333333x + 2

Answer:

Slope = - 1/3

Step-by-step explanation:

Choose the point on the right and move upwards. How many times did you move upwards until you were at the same level as the point on the left? You moved once, which means your rise is 1.

Now from the point where you are at now, move right or left depending on where the point is. In this case, it's on the left which means our run will be negative. Now move left until you reach that point on the left. How many times did you move left? You moved three times, which means your run is 3.

Rise/Run = -1/3

Slope = Rise/Run

Slope: - 1/3

The sine of ∠I is represented by the ratio 63:65

First, let's draw the triangle (see the picture below.)

We need to use it here.

-sin = opposite/hypotenuse

-cos = adjacent/hypotenuse

-tan = opposite/adjacent.

Assuming that ∠I is Ф,

we can see that its opposite side is equal to 63 and the hypotenuse is 65. Therefore,

[tex]sin(I)=\frac{63}{65} \\\\sinI=75^0[/tex]

Step-by-step explanation:

substitute x in equation 2

y= 2(10) -6

y= 20 - 6

y= 14

substitute y in equation 2

14 = 2x - 6

-2x= -6-14

-2x= -20

divide both sides by -2

y= 14, x= 10

Part A

Explanation:

Refer to the converse of the corresponding angles theorem. The original version is stated as part A, and the converse is marked in bold above.

Conditional statements are of the form "if this, then that". Symbolically we can use the template "If P, then Q". The P and Q are placeholders for logical statements.

The converse of "if P, then Q" is "If Q, then P". We swap the positions of P and Q. Do not negate either piece.

========================================================

Part B

Explanation:

Recall that for any triangle, the three interior or inside angles always add to 180 degrees. In short: A+B+C = 180. If C = 70, then A+B = 180-C leads to A+B = 180-70 and A+B = 110. This process can be reversed.

========================================================

Part C

Explanation:

For more information, check out the converse of the alternate interior angles theorem. The regular version of the theorem is "If two lines are parallel, then the alternate interior angles are congruent".

The converse of this theorem flips things to say: "If alternate interior angles are congruent, then the lines are parallel".

The triangles with the side lengths 10 ft, 24ft, 26 ft, is a right triangle while a triangle with side lengths of 7 yd, 5 yd, 9 yd is NOT based on the Pythagorean theorem.

A triangle is said to be a triangle based on the Pythagorean theorem, if the square of the longest side equals the sum of the squares of the other smaller sides of the triangle.

9² = 7² + 5²

81 = 74 (NOT TRUE), therefore, the triangle with the side lengths 7 yd, 5 yd, 9 yd, is not a right triangle.

26² = 10² + 24²

676 = 676 (TRUE), therefore, the triangle with the side lengths 10 ft, 24ft, 26 ft, is a right triangle.

The number of laps that Swimmer A swam was 50 laps.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Let we suppose that:

Swimmer A swam x laps

Swimmer B swam y laps.

Then, according to the given data, we have:

x    +    y   =   175   laps

y    =   25   +  2x  

(25 more than twice of laps of A is the number of laps of B).

Thus, we get a system of two equations:

x   +   25  +  2x  =   175

3x   +  25    =   175

3x   =   175  -  25  =  150

x   =   50

As x is the number of laps Swimmer A swam, thus, the number of laps that Swimmer A swam was 50 laps.

Step-by-step explanation:

The age of the bird skeleton is 6539.

An exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Here, N =[tex]N_{0}.e^{-0.0001t}[/tex]

             = 52% N₀

[tex]e^{-0.0001t}[/tex] = 0.52

-0.0001 t = ln 0.52

t = -10000 ln 0.52

t = 6539

Equation

Option A

Answer:

Step-by-step explanation:

Consider the end points (-7,-1) and (-5,-9)

The center is the mid point between these two points.

The value of center is,

(h,k) = ((-7-5)/2, (-1-9)/2)

(h,k) = (-12/2,-10/2)

(h,k) = (-6, -5)

If the center (h,k) = (-6, -5) and radius is r then the equation of the circle is,

Equation of Circle,

((x-h)^2)+((y-k)^2) = r^2

((x+6)^2)+(y+5)^2 = r^2

Hence, the answer is ((x+6)^2)+(y+5)^2 = r^2.

Answer: A. negative 3 over 5 is located on the right of −2

Step-by-step explanation:

On a number line, the greater numbers are to the right and the smaller numbers are to the left.

If a log has no base written, you should generally (in algebra classes) assume that the base is 10

we raise 10 to the power log 57.9/c = 57.9/c

and 10 to the power 0.293 = 1.9633602768

so 57.9/c = 1.96

c = 57.9 /1.96 = 29.5

In the given fraction, we have the value of 1 divided in four portions and we just have to identify which portion does A and B fall into

Answer: B

Step-by-step explanation: on Edge (*^*)

The Pythagorean theorem is also known as the Pythagoras' theorem. The height of the triangle is 12cm.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.

Given a=10cm and b=13cm, therefore, the height of the triangle can be found using the Pythagoras theorem, therefore,

AB² = AD² + BD²

13² = AD² + 5²

169 = AD² + 25

AD = 12cm

Hence, the height of the triangle is 12cm.
