Answer:

x = 40

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

So first you would do 12+8=20

Then you would do 20÷0.5=40

Now you want to check your answer

0.5x40=20 and 20-8=12

So x=40

A summer biathalon-style race requires running a certain distance, and then biking a distance 2 miles more than the length of the run. One athlete has a running speed of 6 miles per hour, and a biking speed of 10 miles per hour, and completes the event in 90 minutes. How long, in miles, is each segment of the race

Answers

Answer:

The run is 4.875 miles long, while, the bike is 6.875 miles long.

Step-by-step explanation:

Let d = running distance and d' = biking distance.

Given that d' = d + 2 and v = running speed = 6 mph and v' = biking speed = 10 mph.

Since time, t = distance/speed, running time, t = running distance/running speed = d/6 and biking time, t' = biking distance/biking time = d'/10 = (d + 2)/10.

Since the total time, t" = 90 minutes = 1.5 hours,

t + t' = t"

So, d/6 + (d + 2)/10 = 1.5

multiplying through by the L.C.M, 30, we have

30 × d/6 + 30 ×(d + 2)/10 = 30 × 1.5

5d + 3(d + 2) = 45

expanding the brackets, we have

5d + 3d + 6 = 45

collecting like terms, we have

8d = 45 - 6

8d = 39

d = 39/8

d = 4.875 miles

d' = d + 2 = 4.875 + 2 = 6.875 miles

So, the run is 4.875 miles long, while, the bike is 6.875 miles long.

√43/8 can not be a rational number. Because the numerator of the fraction is not an integer.

Therefore, option C i.e. irrational is correct.

Step-by-step explanation:

What is a rational number?

We know that a rational is a number that can be expressed in the form of a fraction p/q of two integers p and q.

Where

p is a numerator q is a non-zero denominator

Given the number

√43/8

here

The denominator 8 is an integer but the nominator √43 is not an integer.

So,

√43/8 can not be a rational number. Because the numerator of the fraction is not an integer.

Therefore, option C i.e. irrational is correct.

What is the area of the real object that the scale drawing models?
Scale factor: 1:5
Area =
12 square cm
Scale drawing
Object

Answers

Answer:

Step-by-step explanation:

12 x 5 = 60

The area of the real object that the scale drawing models will be 300 square cm. Thus, the correct answer is option (A).

Given:

For Object
Scale factor: 1:5

For Scale drawing

Area = 12 square cm

The scale factor of 1:5 means that every unit on the scale drawing represents 5 units in the real object.

Since area is a two-dimensional measurement, the scale factor for area will be the square of the linear scale factor.

Here, the linear scale factor is 1:5, which means that each unit on the scale drawing represents 5 units in the real object.

Therefore, the area scale factor will be (1:5)² = 1:25.

If the area of the scale drawing is 12 square cm, then the area of the real object that the scale drawing models will be 12 × 25 = 300 square cm.

Therefore, the correct answer is:

A. 300 square cm.

Yoko needs 300 copies of her resume printed. Dakota Printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies. If the number of sets of 100 resumes is represented by r, express the cost of the resumes c(r) algebraically as a piecewise function How much will 300 copies cost including a sales tax of 4 1/2%? Round to the nearest cent.

Answers

Answer:

29.79 should be the answer

Step-by-step explanation:

200 copies 19.50 + 9.00 for 100 copies = 28.50 + 4% = 29.79

The cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2 and =$29.78 is the cost of 300 copies including a sales tax of 4 1/2

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Dakota Printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies.

Let r be the number of sets of 100 resumes.

c(r)=$19.5 when r represent an integer and is less than 2

c(r)=$19.5+(r-2) ($9) (1+0.045)

c(r)=$19.5+(r-2) ($9) (1.045) when r represent an integer and is greater than 2

the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)

=$28.5+$28.5(0.045)

=$28.50+$1.28

=$29.78

Hence, the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2 and =$29.78 is the cost of 300 copies including a sales tax of 4 1/2
