Answer:

x=(h)

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The area (A) of the triangle is the product of its length (l) and width (w). A = l x w. Since the width is 2 m shorter than the length, it may be expressed as w = l -2. The equation for area becomes,

                         A = l x (l - 2)

Substituting the known area and rearranging the equation gives,

                          l(l - 2) = 168.

Answer:

A

Step-by-step explanation:

Let length be "l"

width = l-2 m

Area of rectangle = length * width

so l(l-2) = 168

P.S: L= 14 cm

answer is 4/5

Answer:

t = 5

Step-by-step explanation:

Given r varies directly as t³ then the equation relating them is

r = kt³ ← k is the constant of variation

To find k use the condition r = 54 when t = 3 , then

54 = k × 3³ = 27k ( divide both sides by 27 )

2 = k

r = 2t³ ← equation of variation

When r = 250 , then

250 = 2t³ ( divide both sides by 2 )

125 = t³ ( take cube root of both sides )

[tex]\sqrt[3]{125}[/tex] = t , that is

t = 5

Answer:

3^15/5^16

Step-by-step explanation:

(3^3 x 3^6 x 5^-4) / (3^-6 x 5^12)

= (3^3 x 3^6 x 3^6) / (5^12 x 5^4)

= 3^15 / 5^16

Step-by-step explanation:

I think you made a mistake with the equation.

because that property, that you presented, did not exist.

but

3(x+4) = (x+4)3 exists

and it is the commutative property of multiplication (a×b = b×a).

Use Pythagorean to find the distance through the field:

Difference between two options:

Answer:

It is faster to walk through the field and directly to Ah Chong's house.

The difference between the distance via the road and through the field is 26 m.

Step-by-step explanation:

The scenario can be modeled as a right triangle (see attached diagram).

⇒ Total distance = 195 + 28 = 223 m

To calculate this distance (hypotenuse of the right triangle), use Pythagoras Theorem.

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

[tex]\implies 195^2+28^2=c^2[/tex]

[tex]\implies c^2=38025+784[/tex]

[tex]\implies c^2=38809[/tex]

[tex]\implies c=\sqrt{38809}[/tex]

[tex]\implies c=197[/tex]

Therefore, the distance for option 2 is 197 m.

Option 1 - Option 2 = 223 - 197 = 26 m

As 197 < 223, it is faster for Rahmat to walk through the field and directly to Ah Chong's house (option 2).

The third side of a triangle is greater than the difference and less than the sum of the lengths of the two given sides.         6 - 4 = 2  and 6 + 4 = 10

So the third side is between 2 and 10.

Emily buys 3 pencils for 51p

Work out the price of 4 pencils.

51 : 3 * 4 = 68p

Answer:

68

Step-by-step explanation:

We can write a ratio to solve

3 pencils      4 pencils

------------- = -------------

51 p                x

Using cross products

3x = 51*4

3x = 204

Divide by 3

3x/3 = 204/3

x = 68

Answer:

your answer is 4+3

Step-by-step explanation:

If the mean score is 55% and the s.d. is 15%, then a test score of at least

55% + 1.5 × 15% = 77.5%

falls in the A range.

The next cutoff score is 0.5 s.d. from the mean, which is

55% + 0.5 × 15% = 62.5%

so any test score between 62.5% and 77.5% is in the B range.

The next cutoff is

55% - 0.5 × 15% = 47.5%

so a score between 47.5% and 62.5% gets a C.

The lower limit of the next range is

55% - 1.5 × 15% = 32.5%

so 32.5% - 47.5% gets a D.

Anything lower than 32.5% is an F.
