The distance the ladder reaches up the wall is 289 cm. The correct option is E  289 cm

The Pythagoras' theorem states that, in a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides

Let the length of the ladder be l

The distance of the foot of the ladder from the wall be f

and the distance the ladder reaches up the wall be h

By applying Pythagoras' theorem, we can write that

l² = f² + h²

From the given information,

l = 3m = 300 cm

f = 80 cm

Putting the parameters into the equation, we get

300² = 80² + h²

90000 = 6400 + h²

Then,

h² = 90000 - 6400

h² = 83600

∴ h = √83600

h = 289.1366

h ≅ 289 cm

Hence, the distance the ladder reaches up the wall is 289 cm. The correct option is E  289 cm

Answer:

a. strong

Step-by-step explanation:

i'm pretty sure it's strong because each dot is a different salamander's weight and number of spots, and the line in the middle is a good average. It is not negative because it goes up, and it is not parabolic because it is a straight line. Hope this helps! :)

Answer:

2 days

Step-by-step explanation:

We need to pay $63.68 per DAY and $0.10 per MILE, while staying BELOW the budget of $170... therefore,

We are also already given m, which is 250 miles (The amount she plans to travel.) Solve for d.

In other words, the theoretical maximum amount of time she can rent before exceeding her budget is 2.777 days. That's not practical though so we will round the final answer DOWN to 2 days to be safe and stay within budget.

Answer:

$2.76

Step-by-step explanation:

Price per pound times the number of pounds Ginny bought

Bananas:

2.2*0.49 = 1.078 -> 1.08

Grapes:

1.3*1.29 = 1.677 -> 1.68

Now, to find the total cost of both, add the prices together

1.08 + 1.68 = 2.76

Answer:

$2.76

Step-by-step explanation:

one pound of bananas cost $0.49 , multiply this cost by 2.2 to find the cost at this weight.

2.2*0.49=1.078=1.08

1.3*1.29=1.677=1.68

1.08+1.68=2.76

Daytime= 50

Answer:

1. x>18    2.x<-18     3. x>21     4. x>-7     5. x<2     6. x>-2     7. x<12    8.x<-6

Step-by-step explanation:

1. x/2>9 Pretend the inequality is an equal sign...

x/2=9 *2            x=18

If x>18; 20>18

20/2 = 10

10>9 so it works

If x<18      10<18

10/2 = 5

5<9 so it dosent

2. x/-2>9

x/-2=9

x=-18

If x>-18

0>-18

0/-2=0

0<9 so it doesent work.

x<-18; x=-20

-20/-2=10

10>9 So it works

3. x-7>14 --> x-7=14 ---> x=21

If x>21; x=22 --> 22-7=15; 15>14 (it works)

If x<21; x=20 --> 20-7=13; 13<14 (so it does not work)

4. x-7>-14 --> x-7=-14 --> x=-7

If x>-7; x=0 ---> 0-7=-7 --> -7>14 (so it works)

If x<-7; x=-10 ---> -10-7=-17 --> -17<14 (so it does not work)

5. 5x<10 --> 5x=10 --> x=2

If x>2 x=3 --> 5*3=15 15>10 (does not)

If x<2 x=1 --> 5*1=5 5<10 (works)

6. -5x<10 -5x=10  x=-2

If x<-2 x=-3 -3*5=-15 -15<10 (no)

If x>-2 x=0 5*0=0 0<10 (works)

7. x-3<9  x-3=9 x=12

if x>12 x=13 13-3=10 10>9

If x<12 x=10 10-3=7 7<9 (works)

8. x-3<-9 x-3=-9   x=-6

if x>-6; x=13; 13-3=10 10>-9

if x<-6 x=-10 -10-3=-13   -13<-9 (works)

I believe the total is $211.27.

After doing multiple searches on the internet, I believe that tax rate is a percentage of the product that is added to the total cost.

9 percent of 193.84 is 17.4456, which rounds up to 17.44, and 17.44 added to 193.84 is 211.27.

Please, if something isn't correct here, don't refrain to tell me, and I will correct my mistake. Thank you.
