Answer: 3/11 = 0.27272727272727, -5/8 =  0.625

Step-by-step explanation:

23. 3/11 as a decimal is 0.27272727.

24. 5/8 as a decimal is 0.625.

25. 7/10 as a decimal is 0.7.

26. 2 5/7 as a decimal is 2.71428571.

And lastly, 27. -1 80/99 as a decimal is 1.888888.

Answer: 17/100

Step-by-step explanation: I first made 8/10 into 80/100 and then i did 97-80 which is 17 so the answer is 17/100.

Answer:

( -1, -1 )

Step-by-step explanation:

Just multiply the scale factor with the coordinates

-3 × [tex]\frac{1}{3}[/tex]

= [tex]\frac{-3}{3}[/tex]

= -1

So the coordinates are :

( -1, -1 )

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:

6

Step-by-step explanation:

2+8-11+7=6

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)

Answer:

A, 120 degrees

Step-by-step explanation:

=============================================================

Explanation:

Triangle ABC is equilateral, so all three sides are the same length. This means the three angles are also the same measure. Call each interior angle x.

The three angles add to 180, so x+x+x = 180 solves to x = 60. Each interior angle is 60 degrees.

Angle DAC is an exterior angle of measure 180-x = 180-60 = 120 degrees

------------

Or another method you could use is the fact that all exterior angles of any polygon add to 360.

Since we have n = 3 sides, this means each exterior angle of an equilateral triangle is 360/n = 360/3 = 120 degrees

We consider this a regular polygon because all sides are the same length and all angles are the same measure. So the formula for the exterior angle measure 360/n would apply to any regular polygon and not just triangles.

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

B. 816

Step-by-step explanation:

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:

63/54 or 63:54

a/b so since 63 is the lowest in a, it will be on the top and 54 is b and it's the highest one between both of them.

Don't count as this correct but good luck!

Answer:

63:54
