The length of a rectangle is 3 less than twice the width. The perimeter of the rectangle is 66. Find the length and width of the rectangle.

Answers

Answer 1

Answer:

15.

Step-by-step explanation:

L + L + W + w = 66

L= w+3

W+3 + w+3 + w + w = 66

4xw + 6 = 66

4xw = 66 - 6

4xw = 60

W + W +w +w =60

W= 60/4

W=15

L = 15+3 (=18)

15+15+18+18=66

Answer:

  622

Step-by-step explanation:

The n-th term of an arithmetic sequence is given by the formula ...

  an = a1 +d(n -1)

where a1 is the first term (6), and d is the common difference (14-6=8).

Then the 78th term is ...

  a78 = 6 + 8(78 -1) = 6 + 616 = 622

The 78th term is 622.

Answers

Use the quadratic formula where -15 = a, 7 = b, 23 = c:  [tex]\frac{-b +- \sqrt{b^2 - 4ac}}{2a}[/tex]

Plug in the values: [tex]\frac{-7 +- \sqrt{7^2 - 4(-15)(23)}}{2(-15)}[/tex]

And get: [tex]\frac{-7 +- \sqrt{49 +1380}}{-30}[/tex]

Which simplifies to: [tex]\frac{-7 +- \sqrt{1429}}{-30} = (-7 + 37.8021163)/-30 OR (-7 - 37.8021163)/-30 = 30.8021163/30 OR -44.8021163/30[/tex]

Those are approximately 1 and -1.5

What is the equation for the line perpendicular to the line y=−x+20 that passes through the point (−4, 2)?

Answers

Answer:

y = x + 6

Step-by-step explanation:

A line that is perpindicular to y = -x + 20 would be y = x. Now, we have to solve for the y-intercept. Knowing the line must cross through (-4,2) we can solve for the y-intercept using the equation y = x which is just up one over one. Going over 4 units to get to x = 0 means going up 4 units to get to y = 6. Now we know the y-intercept is 6. This means the final equation is y = x +6.

What is 2/3 divided by 4/5???????

Answers

Answer:

10/12 also 5/6

Step-by-step explanation:

Answer:

10/12 or the simplified version 5/6

Step-by-step explanation:

you have to multiply 2/3 by the reciprocal of 4/5 which is 5/4

so you write down 2/3 times 5/4 (just multiply across so it's 2x5 over 3x4)

2x5=10 and 3x4=12

10 is the numerator and 12 is the denominator

simplify if the problem calls for it by dividing the top and bottom numbers by 2

y = 8x - 6
y= 5x +9

Answers

Answer:

x = 5

y = 34

Step-by-step explanation:

Sub y = 8x - 6 into second equation (y = 5x + 9)

8x - 6 = 5x + 9

Rearrange by collecting like terms

8x - 5x = 9 + 6

3x = 15

x = 5

Sub x = 5 into first equation (y = 8x - 6)  

y = (8*5) - 6

y = 40 - 6

y = 34

X=5 and y= 34 are the values

What is the combined weight of the bee and the pollen? Express your answer in scientific notation.

Answers

Answer:

0.18 g

Step-by-step explanation:

Weight of honeybee = [tex]1.2\times 10^{-1}\ \text{g}[/tex]

Weight of pollen = [tex]6\times 10^{-2}\ \text{g}[/tex]

The above values can be written in the following ways

[tex]1.2\times 10^{-1}\ \text{g}=0.12\ \text{g}[/tex]

[tex]6\times 10^{-2}\ \text{g}=0.06\ \text{g}[/tex]

Weight mass = [tex]0.12+0.06=0.18\ \text{g}[/tex]

The combined weight of the honeybee and the pollen is 0.18 g.
