The length of Dwight's garden is 12.5 meters. Dwight measured it but made a measurement error of 6%. Find the lowest and highest measurement Dwight could have made. Show your work.

Answers

Answer: See Explanation

Step-by-step explanation:

From the question, The length of Dwight's garden is 12.5 meters but he measured it and made a measurement error of 6%.

The lowest measurement Dwight could have made will be:

= 12.5 - (6% × 12.5)

= 12.5 - (0.06 × 12.5)

= 12.5 - 0.75

= 11.75 meters

The lowest measurement Dwight could have made will be:

= 12.5 + (6% × 12.5)

= 12.5 + (0.06 × 12.5)

= 12.5 + 0.75

= 13.25 meters

x = -9/5

Step-by-step explanation:

Answer:

x=28/5

Step-by-step explanation:

need more help? im glad to

first we need to simplify both sides :

5x + 13 * -2 = 2

5x +  -26 = 2

5x - 26 = 2

Then we add 26 to both sides:

5x - 26 = 2

    +26   +26

5x = 28

Then  we divide both sides by 5:

5x/5  = 28/5

x = 28/5

3. What is the sum of the interior angles of a polygon with 32 sides?

Answers

Answer:

Step-by-step explanation:

To find the sum of an interior angle of a polygon, you have to follow these steps:

Interior angle= ( n - 2 ) ×180° all over n

So interior = ( 32 - 2 ) × 180° all over 32

Interior = 30 × 180 all over 32

Therefore your interior angle should be 168.75°

A. Write an equation for Leo's distance from the starting point after riding for x hours. Write an equation for Juan's distance from the starting point if he starts h hours after Leo.

Answers

Answer:

Simply apply the expression

Speed= distance/time

Step-by-step explanation:

The question is not complete, although, we can provide a solution to what it is trying to ask for

Step one:

given data

For Leo, let the distance that Leo covers be y meters

and let the distance that Juan covers be f meters

From speed = distance/time

for Leo, given that he traveled for x hours, his distance will be

d= y*x

for Juan, given that he traveled for h hours, his distance will be

d= f*h

1) f(5) = 7

2) f(0) = -2

3) p(-7) = -17

Step-by-step explanation:

1) f(a) = 2a - 3

f(5) = 2 · 5 - 3 = 10 - 3 = 7

2) f(x) = 2x - 2

f(0) = 2 · 0 - 2 = 0 - 2 = -2

3) p(n) = 2n - 3

p(-7) = 2 · (-7) - 3 = -14 - 3 = -17

There were 275 students who rode the bus which represents 60% of school enrolment how many students enrolled

Answers

Answer:

458 (or 459 if you overestimate)

Step-by-step explanation:

Let's work backwards. we know that the 275 students are 60% of the total students enrolled, which we'll denote with x. Therefore:

0.6x = 275

Now divide both sides by 0.6 to get the answer:

x = 458.3

You can't have .3 students, so the answer is either 458 or 459 students, depending on if you want to over or underestimate.

Hope this helps!

Kim is 5 years older than Scott.
Kim's mum is 3 times Kim's age.
Scott's dad is 3 times Scott's age.
How much older is Kim's mum than Scott's dad?

Answers

Answer: 15 years

Step-by-step explanation:

Given :  Kim is 5 years older than Scott.

Kim's mum is 3 times Kim's age.

Scott's dad is 3 times Scott's age.

Let age of Scott = y years

Then Kim's age = (y+5) years

Kim's mum age = [tex]3\times (y+5)=3y+15[/tex] years

Scott's Dad age = [tex]3\times y=3y[/tex] years

Difference between Kim's mum age and Scott's Dad age = Kim's mum age - Scott's Dad age =  (3y+15) - (3y) = 15

Thus Kim's mum is 15 years older than Scott's dad.

Answer:

15

Step-by-step explanation:

Kim .           Scott

+5 (y+5)      -5 . (y)

let's give them a random age

Kim .           Scott

16 .                11

Mum           Dad           x3

48 .              33

48-33=15

So Kim's mum is 15 years older than Scott's dad

Use the given similar triangles to find the value of x
I need the answer fast please!!

Answers

Answer:

I believe the answer is x=7

Step-by-step explanation:

3x and 4x-1 are corresponding sides and so are 14 and 18.

You cross multiply with the smaller triangle lengths at the top.

3x/(4x-1)= 14/18

Cross multiply to get

18(3x)= 14(4x-1)

54x=56x-14

Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)

you get 14=2x and divide 14 by 2 to get x=7
