What Is The Perimeter?

Answers

Answer 1

Answer:

56 yd ??

Step-by-step explanation:

Sorry if wrong i think it is this

Answer 2

Answer:

28 yards

Step-by-step explanation:

this is a right angled triangle

this question will be solved by Pythagoras theorem

which states square of hypotenuse=square of legs

so 35= 21sqr+b sqr

1225=441+b sqr

b sqr= 1225-441

b sqr=784

b= sqr root of 784

= 28 yards

perimeter=1/2multiplied to base to height

=(21*35)/2

= 367.5

2. Some kids went on a bike ride. The ride was six hours long and the kids traveled 54 miles. For part of the ride they biked at a speed of 7 mph and for part of the ride they biked at a speed of 11 mph. For how long did they bike at the first speed, and for how long at the other speed?


3. I left Boston for Washington, DC, at 7:00 am. At first, my speed was 55 mph; then it was 75 mph. I traveled 630 miles in 10 hours. At what time did I begin to drive faster?


Thanks!

Answers

Answer: 1= 41

2= 3 hours biking at the other speed.

3= We began to drive at 75 mph at 1:00 p.m

Step-by-step explanation:

3= x/55 + (630 - x)/75 = 10

75x + 55 * (630 - x) = 41,250 (4,125 as Lowest common multiple)

75x + 34,650 - 55x = 41,250

20x = 41,250 - 34,650 (Subtracting 34,650 at both sides)

20x = 6,600

x = 6,600/20

x = 330 ⇒ 630 - x = 300

Time we drove at 55 mph = 330/55 = 6 hours

Time we drove at 75 mph = 300/75 = 4 hours

We began to drive at 75 mph at 1:00 p.m. (7 am + 6 hours)

Consider the relationship 7r+2t=7. a. Write the relationship as a function r=f(t).

Answers

Answer: r = 2/7 -t

Step-by-step explanation: solve r from equation

7r = 2-7t l:7. r = 2/7 - t

The relationship as a function r=f(t) is [tex]\rm f(t)=\dfrac{7-2t}{7}\\\\[/tex].

What is the equation?

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

Consider the relationship;

7r+2t=7

Substitute r = f(t) in the equation

[tex]\rm 7r+2t=7\\\\7f(t)+2t=7\\\\ 7f(t)=7-2t\\\\f(t)=\dfrac{7-2t}{7}\\\\[/tex]

Hence, the relationship as a function r=f(t) is [tex]\rm f(t)=\dfrac{7-2t}{7}\\\\[/tex].

if one point is located at (-5,3) and another point is located at (7,-4). find the distance between the points. round to the nearest tenth.​

Answers

Answer:

13.9

Step-by-step explanation:

Use the distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\[/tex]

The square root of 193 rounded to the nearest tenth is 13.9.
