Given:

Perimeter of a parallelogram = 64 cm

Length = 3 times larger than the width

To find:

The length of the parallelogram.

Solution:

We know that, the perimeter of the parallelogram is:

[tex]P=2(l+w)[/tex]

Where, l is length and w is width of the parallelogram.

We have, l = 3w and P=64.

So,

[tex]64=2(3w+w)[/tex]

[tex]64=2(4w)[/tex]

[tex]64=8w[/tex]

Divide both sides by 8.

[tex]8=w[/tex]

Now,

[tex]l=3w[/tex]

[tex]l=3(8)[/tex]

[tex]l=24[/tex]

Therefore, the length of the parallelogram is 24 cm.

Answer: [tex]\frac{40}{3}\ \text{hours}[/tex]

Step-by-step explanation:

Nancy can do typing job in 8 hours

i.e. in 1-hour nancy can  [tex]\frac{1}{8}[/tex] part of work

Together they can do that work in 5 hours

or in 1 hour [tex]\frac{1}{5}[/tex] part of work is done

suppose Carole takes x hours for the work

so, in 1 hour [tex]\frac{1}{x}[/tex] part is done

If both work together for 1 hour then we can write

[tex]\frac{1}{8}+\frac{1}{x}=\frac{1}{5}[/tex]

[tex]\frac{1}{x}=\frac{1}{5}-\frac{1}{8}[/tex]

[tex]x=\frac{40}{3}\ \text{hours}[/tex]

Answer:

260 miles

Step-by-step explanation:

Given that,

Total distance driven by Mr. Chen everyday = 26 miles

He drives the same distance to get back home.

It means total distance driven by Mr. Chen to go and come back = 2(26) = 52 miles

We need to find how many miles does he drive during a 5-day work week.

Total distance = 5×52

= 260 miles

Hence, he will drive 260 miles during a 5 day work week.

Answer:

False

Step-by-step explanation:

Notice how the negative symbol is outside the first number and inside the first number. If the negative symbol is outside the absolute value, the number will remain negative. If the negative symbol is inside the absolute value, the number will turn to positive.

Answer:

The 100th term will be;

10(0.5)^99

Step-by-step explanation:

Firstly, we need the common difference and the first term

The first term is 10

The common difference is 5/10 = 1/2

Now, the formula for the nth term of a geometric sequence is;

ar^n-1

So, for the nth term, we have;

ar^(100-1)

= ar^99

So we have

10(1/2)^99

Answer:-2/3

Step-by-step explanation:the problem is asking for the slope of (0,2) and(3,0). The formula for this problem is y2-y1 over x2-x1. And if your writing this formula down write it like a fraction with y on top and x on bottom. (x,y) (x2,y2). You take the 0 from the second set and the 2 from the first set and subtract them to get -2. Then you take the 3 from the sea d set and the 0 from the first set and you subtract them to get 3. That’s how you get the answer of -2/3.

Answer:

(2, 2) ; (4, 4) ; (6, 6)

(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

Step-by-step explanation:

(1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)

Evaluating the ratio of each pair :

(1, 2) = 1/2 = 0.5

(2,3) = 2/3 = 0.67

(4, 7) = 4/7 = 0.57

(2,2) = 2/2 = 1

(4, 4) = 4/4 = 1

(6, 6) = 6/6 = 1

(3, 1) = 3 /1 = 3

(4, 1) = 4 / 1= 4

(5,1) = 5 / 1= 5

(4, 1) = 4 / 1 = 4

(8, 2) = 8/2 = 4

(12,3) =12/3 = 4

(2, 1) = 2/1 = 2

(4,3) = 4 / 3 = 1.33

(5, 4) = 5 / 4 = 1.25

Pairs with equivalent ratios :

Ratio of 1;

(2, 2) ; (4, 4) ; (6, 6)

Ratio of 4:

(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

Answer:

Diego weighs 85 lbs.

Step-by-step explanation:

Answer:the length and width of the rectangle are 12 and 8 respectively

Step-by-step explanation:

Step 1

The perimeter of a rectangle is 2l + 2w  where l= length and w= width giving us that

2l+2w=P

2l + 2w = 40

2(l+w)= 40

l +w = 20

Also we were given The difference between the length and width of a rectangle is 4 units giving us that

l-w= 4

Here our systems of equation to solve the problem

l-w= 4----- Equation 1

l +w = 20-----Equation 2

Step 2

I-w=4---- Equation 1

l +w = 20---Equation 2

Adding equation 1 and 2

I-w=4

+l +w = 20

2l =24

l=24/2

=l=12

To find w, we put the value of l=12 into equation 1

I-w=4

12-w= 4

w= 12-4

w=8

Therefore the length and width of the rectangle are 12 and 8 respectively

Answer:

Step-by-step explanation:

so g(5) mean x = 5 and you just plug 5 into the equation

so

g(x)= X^2 - 2X

=> g(5) = 5^2 - 2.5 = 25 - 10 = 15
