A ladder 3m leans against a wall. The foot of the ladder is 80cm from the wall. The distance the ladder reaches up the wall is:

Answers

Answer:

d

Step-by-step explanation:

hope this helps :)

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

Pythagoras' theorem

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: The volume of the figure is D.528 in^3
Step-by-step explanation: To find the volume of the rectangle box you have to use V=whl which is basically multiplying the width times the height times the length and you’ll get 384. After you do that you look for the volume of the pyramid using V=lwh/3. You have to multiply the length, width and height of the pyramid then divide it by 3 and get 144. You add 384 and 144 and get 528 in.
The answer is D) 528in^3

Solve the following one step inequality for the unknown variable

1. x/2>9

2. x/-2> 9

3. x-7 > 14

4. x-7 > -14

5. 5x< 10

6. -5x < 10

7. X-3 < 9

8. x-3 < -9

Answers

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)

Ginny bought 2.2 pounds of bananas at a cost of $0.49 per pound and 1.3 pounds of grapes at a cost of $1.29 per pound. What was the total cost of the bananas and grapes Ginny purchased?

Answers

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

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,

$63.68d + $0.10m < $170

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

$63.68d + $0.10(250) < $170$63.68d + $25 < $170$63.68d < $145d < 2.777

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.

Please help how do you solve this?

Answers

Answer:

A, 120 degrees

Step-by-step explanation:

Answer:  A) 120 degrees

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

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.
