A rectangle has a length of x and a width that is 8 units shorter than twice the length.

Mathematics
1 answer:
erma4kov [3.2K]3 years ago
6 0

Step-by-step explanation:

length = x

width = 2x-8

b.) to get the area you need to multiply the length and the width.

l×w= area

x(2x-8)

2x^2-8x

c.) 2x^2-8x = 10

subtract 10 both sides

2x^2-8x-10 = 0

2(x^2-4x-5) = 0

2(x-5)(x+1) = 0

x = 5

the area would be 10.

Write the equation of a direct variation that passes through the point (-11, 13)
VMariaS [17]
<h2>Answer:</h2>

<u>A direct variation equation is of the form y = m⋅x for some constant value m</u>.

<u>For a direct variation equation passing through</u>

(x,y) = (-11,13)

13 = m × - 11

→ m = - 13/11.

so, as y = m⋅x

y = - 13/11x

<u>Hence, the direct variation equation is [C] - 13/11x</u>.

What is the probability of tossing a coin three times and getting heads<br> each time? *
Serggg [28]

Answer:

probability of tossing a coin 3 times and getting heads each time is 1/8

Step-by-step explanation:

A coin has 2 sides (heads and tails) therefore you have a 50% chance of getting either heads or tails for each toss. Therefore, the probability of getting heads for 1 toss is 1/2. Now, tossing it 3 times and getting heads each time essentially means you would have to do (1/2)×(1/2)×(1/2) which would give you 1/8 as the probability of tossing a coin 3 times and getting heads each time.

Please help me with this ratio. ​
Charra [1.4K]

Answer:

\frac{inches}{minute}

Change the feet to minutes by multiplying by 12, and change the hour to minutes.

Speedy: \frac{240}{60}

Slowpoke: \frac{80}{30}

Cleo: \frac{96}{10}

Speedy is the fastest.

\frac{feet}{hour}

  • Speedy: \frac{20}{1}
  • Slowpoke: \frac{\frac{6.666666667}{.5}}{30}
  • Cleo: \frac{8}{\frac{1}{6}}

Change minutes to feet by dividing and change the minutes to hours by multiplying.
