Brandon enters bike races.He bikes 8 1/2 miles every 1/2 hour. complete a table to find how far Brandon bikes for each time interval.

Answers

Answer 1
Answer: 12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking.SO here are the data that we need:=> 8 and ½ miles = 8.5 miles=> ½ hour = .5 hours or 30 minutesNow, let’s solve for the unit rate=> SO in every 30 minutes he bikes around 8.5 miles=> Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2=> 8.5 * 2 = 17miles=> 17 miles / hour
Answer 2
Answer:

The distance of Brandon’s bike in each interval of time can be represented in the attached Table 1.

Further explanation:

Given:

Brandon enters in to the bike race and he bikes 8(1)/(2)\text{ miles} in every (1)/(2)\text{ hour}.

Calculation:

It is given that in every (1)/(2)\text{ hour} Brandon bikes 8(1)/(2)\text{ miles}.

The distance 8(1)/(2)\text{ miles} is in the form of mixed fraction.

Therefore, the distance 8(1)/(2)\text{ miles} can be written in the form of decimal as follows:

\boxed{8(1)/(2)\text{ miles}\rightarrow8.5\text{ miles}}

 

Brandon bike's8.5\text{ miles} in every (1)/(2)\text{ hour}.

We know that 1\text{ hour} is equivalent to 60\text{ minutes}.

So, 0.5\text{ hour} can be converted into minutes as follows:

\boxed{\begin{aligned}1\text{ hour}\rightarrow60\text{ minutes}\n0.5\text{ hour}\rightarrow30\text{ minutes}\end{aligned}}  

Therefore, in every 30\text{ minutes} Brandon bikes 8.5\text{ miles}.

So, in next 30\text{ minutes} Brandon also bikes 8.5\text{ miles}.

In every 1\text{ hour} Brandon travels \boxed{8.5+8.5=17\text{ miles}}.

In every 1:30\text{ hour} Brandon travels \boxed{17+8.5=25.5\text{ miles}}.

Method 2:

Speed of Brandon’s bike can be calculated as ,

\boxed{\text{Speed}=(d)/(t)}        …… (1)

Here, d is the distance and t is the time.

The distance is 8.5\text{ miles} and time is 0.5\text{ hour}.

Now, substitute d=8.5 and t=0.5 in the equation (1) to obtain the speed as follows:

\begin{aligned}\text{Speed}&=(8.5)/(0.5)\n&=17\text{ miles per hour}\end{aligned}

 

Therefore, the rate of travelling of Brandon’s bike is 17\text{ miles per hour}.

The distance of Brandon’s bike in each interval of time can be represented in the attached Table 1.

Answers

Answer:

1. x = -3

2. x = -3

Step-by-step explanation:

1.

First subtract 2.

4x = -12

Divide by 4.

x = -3

2.

Subtract 12 from both sides.

7x = -21

Divide by 7

x = -3

Ian's science book has 20 fewer pages than his math book. Ian's science book has 250 pages. Which equation can be used to calculate how many pages Ian's math book has? Let the variable p stand for the number of pages in the math book. A. 250 – 20 = p B. 250 = p + 20 C. 20 – p = 250 D. 250 = p – 20

Answers

the answer is simply C. 20-p=250

the math book would have 270 pages so the equation is the letter B.

Answers

Question #1:

The surface area of a prism is the area of the outside of the prism, the volume is how much the inside of the container holds.

Let's find the volume and surface area of the prism given.

V = lwh

Plug in what we know:

V = (18.4)(10.9)(8.7)

Multiply:

V = 1744.872 m^3

SA = 
2(wl hl hw)

Plug in what we know:

SA = 2((10.9)(18.4) + (8.7)(18.4) + (8.7)(10.9))

Multiply:

SA = 2(200.56 + 160.08 + 94.83)

Add:

SA = 2(455.47)

Multiply:

SA = 910.94 m^2

Now find the difference:

Note that these are different measurements.

The volume is measured in cubic meters and the surface area is measured in square meters.

910.94 m^2 = 27493.793 m^3

Find the difference:

27493.793 m^3 - 1744.872 m^3 = 25748.921

Question #2:

The formula for the surface area of a rectangular prism is:

SA = 2(wl + hl + hw)

Plug in what we know:

SA = 2((5)(6) + (3)(6) + (3)(5))

This is the equation we use to find the surface area of this figure.

Multiply:

SA = 2(30 + 18 + 15)

Add:

SA = 2(63)

Multiply:

SA = 126 cm^2
