__

(b) The difference between the bounding rectangle and the lower-left cutout is ...

  (8 cm)(7 cm) -(3 cm)(4 cm) = (56 -12) cm^2 = 44 cm^2

__

(c) The difference between the bounding rectangle and the center cutout is ...

  (13 m)(7 m) -(4 m)(1 m) = (91 -4) m^2 = 87 m^2

__

(d) The difference between the bounding rectangle and the two cutouts is ...

  (20 m)(25 m) -(16 m)(20 m) = (20 m)(25 -16) m = (20 m)(9 m) = 180 m^2

__

(e) The difference between the bounding rectangle and the two cutouts is ...

  (14 m)(12 m) -(12 m)(3 m) = (12 m)(14 -3) m = (12 m)(11 m) = 132 m^2

Answer:

88.88% or 8/9 of the yard is mowed

Step-by-step explanation:

First step is to get the denominator to the same number. Both denominators have a least common multiple of 12.

3/4 * 3/3 = 9/12

2/3 * 4/4 = 8/12

9/12 hours is how long it takes Evan to mow his backyard. He has 8/12 hours of work already done. If we divide the time already passed by the time still needed to mow the backyard, we can get how much of the yard is already mowed.

(8/12) / (9/12)

8/12 * 12/9  

96/108 = 88.88

The equation that could be used to determine x is [tex]\frac{11+x}{53+x} \leq 0.300[/tex].

Inequality is a relation that makes a non-equal comparison between two expressions.

Batting average of William = 11/53

Desired batting average = 0.300

Suppose the number of more hits in a row to have desired batting average =x

Number of hits now =11+x

Number of bats now =53+x

It is given that the batting average should be a minimum of 0.300.

This means [tex]\frac{11+x}{53+x} \leq 0.300[/tex]

Therefore, the equation that could be used to determine x is [tex]\frac{11+x}{53+x} \leq 0.300[/tex].

Answer: 0.023

Step-by-step explanation:

Given that:

Number of green balls = 9

Number of white balls = 8

Total number of balls = 9 + 8 = 17

Drawing with replacement :

Probability of white :

First draw = 8/17

2nd draw = 8/17

3rd draw =. 8/17

4th draw = 8/17

5th draw = 8/17

P(all 5 are white) = 8/17 * 8/17 * 8/17 * 8/17 * 8/17 = 32768/1419857

= 0.0230783

Answer:

A = $5,187.50

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7.5%/100 = 0.075 per year.

Putting time into years for simplicity,

6 months / 12 months/year = 0.5 years.

Solving our equation:

A = 5000(1 + (0.075 × 0.5)) = 5187.5

A = $5,187.50

The total amount accrued, principal plus interest, from simple interest on a principal of $5,000.00 at a rate of 7.5% per year for 0.5 years (6 months) is $5,187.50.

The amount of money she saved after 6 months is $5,187.50.

Chance formula is used to find the quantum or share of commodity in terms of 100. In its simplest form, percent means per hundred. To express a number between zero and one, chance formula is used. It's defined as a number represented as a bit of 100. It's denoted by the symbol, and is majorly used to compare and find out rates.

Given:

r = R/100

r = 7.5%/100

r = 0.075 per year.

Time = 6 months.

        = 6/12 = 1/2 year

So, Amount = 5000(1 + (0.075 × 0.5))

A = $5,187.50

The total amount accrued, principal plus interest is $5,187.50.

Step-by-step explanation:

The following two terms of an arithmetic progression are -6 and -11.

What is an arithmetic sequence?

An arithmetic sequence is defined as a progression of numbers such that the difference between successive terms is consistent. It is also called Arithmetic Progression. The formula for tthe last term of an AP is given as: an = a + (n-1)d, here, a is the first term, n is the number of terms and d is the difference between two successive terms.

Finding the two terms of an arithmetic sequence

The first three terms of an arithmetic sequence are given by:

a1 = 9

a2 = 4

a3 = -1

Now, we want to calculate a4 and a5

Using the formula for calculating the next term of an arithmetic progression, we get,

a4 = a + (n-1)d, where n = 4 and d = 5

a4 = 9 + (4-1)(-5)

a4 = 9 - 15

a4 = -6

Further, a5 = a + (n-1)d, where n = 5 and d = 5

a5 = 9 + (5-1)(-5)

a5 = 9 - 20

a5 = -11

Hence, the next two terms of an AP are -6 and -11.

The solution to the inequality -3( 2j - 11 ) ≥ 8j - 9 can be represented in an inequality form or interval notation form as j ≤ 3 and (-∞,3] respectively.

Given the inequality in the question;

-3( 2j - 11 ) ≥ 8j - 9

First, we simplify using distributive property.

-3( 2j - 11 ) ≥ 8j - 9

-3×2j -3×-11 ≥ 8j - 9

-6j + 33 ≥ 8j - 9

Next, move all terms containing j to the left and all constant to the right.

-6j + 33 ≥ 8j - 9

-6j - 8j ≥ - 9 - 33

-14j ≥ -42

Divide both sides by -14.

Note that, when multiplying or dividing both sides of an inequality by a

negative value, the inequality sign flips directions.

-14j/-14 ≤ -42/-14

j ≤ -42/-14

j ≤ 3

Therefore, The solution to the inequality -3( 2j - 11 ) ≥ 8j - 9 can be represented in an inequality form or interval notation form as j ≤ 3 and (-∞,3] respectively.
