The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.

(A) 12 cm x 4 cm (B) 18 cm x 8 cm (C) 15 cm x 9 cm

Answers

Answer 1

Answer:

(B) 18 cm × 8 cm

Step-by-step explanation:

Perimeter of a rectangle  =  52 cm

2(length + width)  =  52 ==>  l + w  =  26

Let x be the length

width  =  (x/3) + 2

x + (x/3) + 2  =  26

[(3x + x)/3]  + 2 =  26

4x / 3  =  24

4x  =  24 (3)

x  =  6(3) ==>  18 cm

Width  =  (18/3) + 2

=  6 + 2  =  8 cm

So, the required dimension is 18 cm x 8 cm.

Answer 2

Answer:

B. 18 * 8.

Step-by-step explanation:

Let the perimeter be:

52 cm.

Find the numbers for the perimeter:

For A:

(12 cm + 4 cm) * 2 = 32.

That means A is incorrect.

For B:

(18 + 8) * 2 = 52 cm.

That means B is correct.

For C:

(15 + 9) * 2 = 48 cm.

That means C is incorrect.

Correct choice is B.

A machine can pack a 3 ft by 2 ft by 2 ft carton with packing material in 3 seconds. How long would it take to fill a carton that measures 4 ft by 5 ft by 6 ft?
6.4 sec
24 sec
36 sec
30 sec

Answers

1) we calculate the volume of the first carton:

volume=length x width x height

volume=3 ft * 2 ft * 2 ft=12 ft³

Therefore:

A machine can fill 12 ft³ in 3 seconds.

2) we calculate the volume of the second carton.

volume=length x width x heigth

volume=4 ft * 5 ft * 6 ft=120 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

12 ft³---------------------3 seconds

120 ft³--------------------      x

x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.

answer: 30 seconds.

In how many ways can a committee of three men and three women be formed from a group of eight men and seven women

Answers

Answer:  1960

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

Explanation:

Order doesn't matter when it comes to committees without rankings. Each person on the committee is of equal rank to anyone else. This means we'll use a combination instead of a permutation.

We have 8 men and 3 seats to fill for the men. Plug n = 8 and r = 3 into the nCr combination formula

n C r = (n!)/(r!(n-r)!)

8 C 3 = (8!)/(3!*(8-3)!)

8 C 3 = (8!)/(3!*5!)

8 C 3 = (8*7*6*5*4*3*2*1)/((3*2*1)*(5*4*3*2*1))

8 C 3 = (40320)/((6)*(120))

8 C 3 = (40320)/(720)

8 C 3 = 56

This means there are 56 ways to select the three men from a pool of eight.

Through similar steps, you should plug n = 7 and r = 3 into the nCr combination formula to get 7 C 3 = 35. This means there are 35 ways to pick the three women from a pool of seven.

Overall, there are 56*35 = 1960 ways to select the entire committee of 3 men and 3 women (from a pool of 8 men and 7 women).

After 30 baseball games, Bryce Harper had 25 hits and after 100 games he had 165 hits. How many hits would he have after 106 games?(include units)
Find Slope(Rate of Change):
Then Find the Amount After 106 games.

Answers

Answer:

177 hits

Step-by-step explanation:

Let [tex]x[/tex] = number of baseball games

Let [tex]y[/tex] = number of hits

(30, 25) = [tex](x_1,y_1)[/tex]

(100, 165) = [tex](x_2,y_2)[/tex]

Slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{165-25}{100-30} =2[/tex]

Using the point-slope formula to create an equation:

[tex]y-y_1=m(x-x_1)\\\\\implies y-25=2(x-30)\\\\\implies y=2x-35[/tex]

Now substitute [tex]x = 106[/tex] into the equation and solve for [tex]y[/tex]:

[tex]\implies y=(2 \times 106)-35=177[/tex]

Therefore, the number of hits Bryce would have after 106 games is 177

Take 2 points

(30,25)(100,165)

Slope:-

[tex]\\ \rm\hookrightarrow m=\dfrac{165-25}{100-30}[/tex]

[tex]\\ \rm\hookrightarrow m=\dfrac{140}{70}=2[/tex]

Equation in point slope form

[tex]\\ \rm\hookrightarrow y-25=2(x-30)[/tex]

[tex]\\ \rm\hookrightarrow y-25=2x-60[/tex]

[tex]\\ \rm\hookrightarrow 2x-y-35=0[/tex]

Convert to slope intercept form y=mx+b

[tex]\\ \rm\hookrightarrow y=2x-35[/tex]

Put x=106

[tex]\\ \rm\hookrightarrow y=2(106)-35=212-35=177[/tex]

number of games they will play from Day 1 to Day 50 if today is
Day 1? (Exactly 1 game is played per day.)

Answers

Answer:

25 games were played

Step-by-step explanation:

I first found how many games were played in 10 days

and then multiplied it by 5 to know how many games were played in 50 days

(but I am not sure if it is correct since it said that 1 game was played everyday and with rules I am not sure if it is even possible)

feel free to correct me

Answer: 17

Step-by-step explanation:

Lisa and Melinda will play together 8 times

Lisa and Rahul will play together 12 times

Melinda and Rahul will play together 4 times

So total games are 24 -- but they all will play together 4 times.

Since, "exactly 1 game is played per day", they cannot play 2 and 3 together at any day.

So total number will be: (8-4) + (12-4) + (4-4) = 12

Now, we must consider 4 where they played all 3 together; so total number: 12 + 4 = 16

Also, they already played 1 game at 1st day; so total number: 16 + 1 = 17

Betty is having invitations printed for a holiday party. It costs $3.90 to set up the printing machine and $2.44 per invitation. In the equation below, x represents the number of invitations Betty is having printed, and y represents the cost to print the invitations.

y = $2.44x + $3.90

How much will it cost Betty to print 100 invitations?
A.
$392.44
B.
$251.80
C.
$103.90
D.
$247.90

Answers

Answer:

D) $247.90

Step-by-step explanation:

Understanding the equation:

[tex] \underline{\sf{y = 2.44x + 3.90}}[/tex]

y is the dependent function whereas x is the independent function.

(What does this mean?)

The values of y depend on the values of x, I.e., any change in the value of x causes a change in the value of y, meanwhile, the opposite doesn't happen.

x represents the number of invitations y represents the cost to print the invitations

The cost to print the invitation depends on the number of invitations, for real.

Solution to the problem:

The question asks us to find the cost of printing 100 invitations.

Substituting x for 100:

y = (2.44 × 100) + 3.90

y = 244 + 3.90

y = 247.90

Answer:

The value of y obtained for x = 100 is the cost of printing 100 invitations – $ 247.90

The sum of several consecutive natural numbers is 2012. How many numbers were in that sum​

Answers

Answer:

8

Step-by-step explanation:

first number = a, there are n numbers

so last number is a + n - 1

sum = [a + (a + n - 1)} * n/2 = (2a + n - 1) / 2 = 2012

n * (2a + n - 1) = 2012 * 2 = 4024

4024 is even, so n must be even, divisible by 2, 4, 8

4024 = 2 * 2012 = 4 * 1006 = 8 * 503

If n = 2, 2a + n - 1 = 2012, 2a + 2 - 1 = 2012, 2a = 2011, impossible.

If n = 4, 2a + n - 1 = 1006, 2a + 4 - 1 = 2a + 3 = 1006, 2a = 1003, impossible

If n = 8, 2a + n - 1 = 503, 2a + 8 - 1 = 2a + 7 = 503, a = 248

so n = 8, a = 248

Explanation:

Split the graph into separate regions (see the diagram below)

The red trapezoid has the parallel vertical sides of b1 = 1 and b2 = 2. The height of the trapezoid is h = 2

The area of the red trapezoid is

A = h*(b1+b2)/2 = 2*(1+2)/2 = 3

--------------

The blue rectangle has a horizontal side of 2 and vertical side of 2. Its area is 2*2 = 4 square units.

--------------

The pink triangle has a base of 1 and height of 2

area = base*height/2 = 1*2/2 = 1 square unit

--------------

The green triangle has an area of base*height/2 = 2*2/2 = 2 square units

--------------

For any region above the x axis, it gets assigned a positive area. Anything below the x axis gets a negative area to counterbalance the positive areas.

The regions above the x axis add to 3+4+1 = 8 square units. Then we subtract off the area of the green triangle to get 8-2 = 6 square units.

Therefore,  [tex]\displaystyle \int_{0}^{7}f(x)dx = 6[/tex]

Brianna has $2.80 in quarters, dimes and nickels in her purse. She has nine more dimes than quarters and six more nickels than quarters. How many of each coin does she have?

Answers

Answer:

She has 4 quarters, 13 dimes, and 10 nickels in her purse

Step-by-step explanation:

Let q be the amount of quarters, d be the amount of dimes, and n be the amount of nickels she has in her purse. We can use this to set up a system of equations:

25q+10d+5n=280

This is because a quarter is 25 cents, a dime is 10 cents, and a nickel is 5 cents. We also have to convert $2.80 to cents since all our other values are in cents.

d=q+9

She has 9 more dimes than quarters

n=q+6

She has 6 more nickels than quarters

We can solve this system using substitution (substitute q+9 for d and q+6 for n)

25q+10(q+9)+5(q+6)=280

25q+10(q)+10(9)+5(q)+5(6)=280

25q+10q+90+5q+30=280

40q+120=280

Subtract 120 from both sides

40q=160

Divide both sides by 40

q=4

Now we plug this back into the other equations to find the amount of nickels and dimes

d=q+9=4+9=13

n=q+6=4+6=10

She has 4 quarters, 13 dimes, and 10 nickels in her purse
