Answer:

\(\huge\boxed{\sf r = 5}\)

Step-by-step explanation:

Given that,

7q + 35 = 7q + 7r

7q - 7q + 35 = 7q - 7q + 7r

35 = 7r

35/7 = r

5 = r

OR

\(\rule[225]{225}{2}\)

Answer:

r = 5

Step-by-step explanation:

Given statement,

→ 7(q + 5) is equivalent to (q + r)7.

Forming the equation,

→ 7(q + 5) = 7(q + r)

Now we have to,

→ Find the required value of r.

Then the value of r will be,

→ 7(q + 5) = 7(q + r)

Applying Distributive property:

→ 7(q) + 7(5) = 7(q) + 7(r)

→ 7q + 35 = 7q + 7r

Cancelling 7q from both sides:

→ 35 = 7r

→ 7r = 35

Dividing the RHS with number 7:

→ r = 35/7

→ [ r = 5 ]

Therefore, the value of r is 5.

Answer:

\(A(t)=16(0.99948)^t\)

Step-by-step explanation:

The exponential function is modeled using the equation:

\(A(t)=A_o(1\pm r)^t\)

Where the plus sign indicates growth and the negative sign indicates exponential decay.

For an exponential function has a starting value of 16 and a decay rate of 0.52%.

\(A_0=16\\r=0.052\%=0.00052\)

This gives:

\(A(t)=16(1- 0.00052)^t\\A(t)=16(0.99948)^t\)

The function that models this situation is:

\(A(t)=16(0.99948)^t\)

The function f(5)=365 in the given function f(5) = 51x+ 110

A function is a special form of relation where each input has exactly one output. In other words, for each input value, the function returns precisely one value. A relation rather than a function is depicted in the above graph since one is mapped to two separate values. However, if one were instead mapped to a single value, the relationship described above would change into a function. Furthermore, output values might match input values exactly.

The function machine receives the x-values as input. After finishing its operations, the function machine produces the y-values. Any function may be the one within.

One – one function (Injective function) Many – one function. Onto – function (Surjective Function) Into – function.

function f(x), where x = 20x+x+50+30(x + 2)

Find f(5) = 21x + 30x + 110's value.

f(5)= 51*5 + 110 = 255+110 = 365

Consequently, f(5) = 365.

Answer:

The sequence is increasing by 5 at each step. So, we can write:

a1 = 30

a2 = 30 + 5 = 35

a3 = 30 + 25 = 40

a4 = 30 + 35 = 45

a5 = 30 + 4*5 = 50

We notice that the nth term is given by:

an = 30 + (n-1)5

So, the explicit formula for the nth term is:

an = 25n + 5

Find:

  slope-intercept equation for a line through these points

Solution:

When given two points, it often works well to start with the 2-point form of the equation for a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

Filling in the given points, you have ...

  y = (5000 -8000)/(6 -3)/(x -3) +8000

  y = (-3000/3)(x -3) +8000

  y = -1000x +3000 +8000 . . . . eliminate parentheses

  y = -1000x +11000 . . . . the desired equation

The probability that the randomely selected fertilized egg will hatch between 15 days to 17 days as 0.5.

The probability of an event is a number that indicates how likely the event is to occur.

It is expressed as a number in the range from 0 and 1 or it can be expressed using percentage notation, in the range from 0% to 100%

Given is that the probability of a randomely selected fertilized egg will take 21 days to hatch is 0.028.

We can write the probability that the randomely selected fertilized egg will hatch between 15 days to 17 days as -

P{E} = {0.028 + (1 - 0.028)}/2

P{E} =  1/2

P{E} = 0.5

Answer:

  about 133.47 feet

Step-by-step explanation:

That distance is ...

  distance = speed × time

  distance = (65 mi/h)(1.4 s)×(1 h)/(3600 s)×(5280 ft)/(1 mi)

  = (65×1.4×5280)/(3600) = 2002/15 ft = 133 7/15 ft ≈ 133.47 ft

The car will travel about 133 feet before the driver reacts.

The overtime rate of pay is K10.25.

The overtime rate of pay can be calculated by multiplying the basic rate pay by the time-and-a-quarter factor. In this case, the basic rate pay is K8.20.

To determine the overtime rate of pay, we need to calculate one-quarter (1/4) of the basic rate pay, and then add that amount to the basic rate pay. One-quarter of K8.20 is calculated as (1/4) * K8.20 = K2.05.

By adding the calculated overtime amount to the basic rate pay, we get the overtime rate of pay: K8.20 + K2.05 = K10.25.

Therefore, the overtime rate of pay is K10.25.

Answer:

  x = 124

Step-by-step explanation:

You want the value of the exterior angle x°, given that the remote interior angles are 83° and 41°.

The exterior angle of a triangle is equal to the sum of the remote interior angles:

  x° = 83° +41°

  x° = 124°

  x = 124

__

Check

The interior angle adjacent to x° is its supplement:

  180° -124° = 56°

The sum of the interior angles of the triangle is 180°:

  83° +41° +56° = 180° . . . . . true

The theorem we cite above is a consequence of the fact that the missing interior angle is supplementary to both x° and the sum of the other two interior angles. It saves having to find the measure of the missing interior angle.

Step-by-step explanation:

A parallelogram is a quadrilateral with two pairs of parallel sides opposing each other.

A square is a quadrilateral with two pairs of parallel sides opposing each other; however, all four sides must be equal and all angles must equal 90 degrees.

Any quadrilateral that is a parallelogram and not a square has angle measures that are not 90 degrees (or have unequal sides).

Step-by-step explanation:

The cost price of dealer is $512.

We have to find the dealer's cost of refrigerator.

We know that mark up is on dealer's cost.

We have been given the markup as 5%

Let the dealer's cost of refrigerator be x,

Now, we know that there is a markup on it

So, we will calculate the marked up price

Marked up price = (Cost price * Markup percent)/100 + cost price

Marked up price = x*5/100 + x

Marked up price = 5x/100 + x

Marked up price = x/20 + x = (x+20x)20

Marked up price = 21x/20

We know that marked up price is the selling price and we have been given the selling price of the refrigerator

537.60 = 21x/20

537.60*20 = 21x

10752 = 21x

x = 10752/21

x = 512

The dealer's cost price is $512.

Answer:

3 3/5 feet per seconds

Step-by-step explanation:

If a frog jumps 9 3/5 feet in the span of 2 2/3 second, we want to calculate the number of feet it can jump in one seconds.

Since it jumps 9 3/5 feet in the span of 2 2/3 second, we can express this as:

9 3/5 feet  = 2 seconds ... 1

The number of feet per seconds will be expressed as:

x = 1secs.... 2

Divide equation 1 by 2 as shown:

9 3/5 ÷ x = 2 2/3 ÷ 1

48/5x = 8/3

Cross multiply

5x * 8 = 48 * 3

40x = 144

10x = 36

5x = 18

x = 18/5

Express as a mixed fraction:

18/5 = 3 3/5ft/secs

Hence the frog is moving at 3 3/5 feet per seconds
