the value of 21b - 32 + 7 b - 20 b is​

Answer:

A

Step-by-step explanation:

The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are [tex]x[/tex] and [tex]y[/tex].

To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table. We know that [tex]x=2[/tex] and [tex]y=12[/tex], so the constant of proportionality is [tex]\frac{y}{x}=\frac{12}{2} =6[/tex]. Hope this helps!

Answer:

B and D are correct.

Step-by-step explanation:

To find the area of a rectangle, simply multiply its length by its width. In this case, the length of the rectangle is [tex]5[/tex] m and the width of the rectangle is [tex]3[/tex] m, so its area must be [tex]5*3=15[/tex] square meters.

To find the area of a triangle, divide the product of the triangle's base and height by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] and [tex]h[/tex] are the triangle's base and height, respectively. In this case, [tex]b=6[/tex] and [tex]h=5[/tex], so the triangle's area is [tex]\frac{6*5}{2}=15[/tex] square meters.

Now, let's look at the statements.

A: The triangle's area is [tex]15[/tex] square meters, not [tex]30[/tex], so A is incorrect.

B: The rectangle's area is [tex]15[/tex] square meters and the triangle's area is also [tex]15[/tex] square meters. Because the two figures have the same areas, their areas are equal, so B is correct.

C: We've already established that the two figures have equal areas, so one can't have a greater area than the other. Therefore, C is incorrect.

D: The rectangle's area is indeed [tex]15[/tex] square meters, so D is correct.

Hope this helps!

Answer:

B is correct, and D is correct

if you multiply 3 times 5 you get 15 m which is the area for the rectangle, then you have to find the area for the triangle, which you would have to multiply 6 times 5 which you get 30, then divide 30 by 2, which would be 15!

Answer:

[tex]\frac{9}{14} \ chance[/tex]

Step-by-step explanation:

1. Approach

Probability is a way of predicting a future outcome based on given data. In essence, the formula for finding the probability is, [tex]\frac{desired\ outcomes}{total\ outcomes}[/tex].

It is given that

- (63) paid with cash

- (22) paid with a debit card

- (13) paid with a credit card

First, add all of these numbers up to find the total number of customers. Then set up the probability, finally, simplify the fraction by diving both the numerator and denominator by a common factor.

2. Find the total number of customers

Add up all of the given customers, regardless of their payment type.;

[tex](cash)+(credit)+(debit)\\\\= 63 + 22 + 13\\\\= 98[/tex]

(98) total customers.

3. Find the probability

Now set up the probability, remember, the formula for finding the probability is,

[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]

The desired outcome is the number of customers who pay with cash = (63)

The total outcome is the number of customers who when to the business; (98)

Substitute in the numbers and simplify,

[tex]\frac{desired\ outcomes}{total\ outcomes}[/tex]

[tex]\frac{63}{98}[/tex]

Both of these numbers are divisible by (7), hence divide the fraction by (7)

[tex]\frac{9}{14}[/tex]

you should know that the sum of interior angles of a hexagon is 720 so

[tex]4x - 10 + 2x + 8 + x - 12 + 7x + 3x + 135 = 720 \\ 17x = 121 \\ x = \frac{121}{17} = 7.11764[/tex]

Answer:

n = - 12

Step-by-step explanation:

n/9 + 2/3 = - 2/3

n/9 = - 2/3 - 2/3

n/9 = - 4/3

n = 9(- 4/3)

n = -36/3

n = - 12

Answer: 0.5

Step-by-step explanation:

Given

Line passes through [tex](-10,-30), (0,-25), (10,-20), \text{and}\ (20,-15)[/tex]

The slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Taking any two points: (0, -25) and (20,-15)

Slope is

[tex]\Rightarrow m=\dfrac{-15-(-25)}{20-0}=\dfrac{10}{20}\\\\\Rightarrow m=0.5[/tex]

Answer:

The scale factor is 4

Step-by-step explanation:

Given

See attachment for parallelograms

Required

Determine the scale factor (k)

Using sides FG and F'G' as a point of reference:

[tex]FG = 2\ units[/tex]

[tex]F'G' = 8\ units[/tex]

The scale factor (k) is calculated as:

[tex]k = \frac{New}{Original}[/tex]

[tex]k = \frac{F'G'}{FG}[/tex]

[tex]k = \frac{8\ units}{2\ units}[/tex]

[tex]k = 4[/tex]

Answer:

[tex]d. \: \: \: 25 {x}^{6} [/tex]

Step-by-step explanation:

Given,

Side of the square

[tex] = 5 {x}^{3} [/tex]

Therefore, area of the square = side × side

[tex] = {5x}^{3} \times 5 {x}^{3} [/tex]

[tex] = 5 \times 5 \times {x}^{3 + 3} [/tex]

[tex] = 25 {x}^{6} [/tex]

Answer:

Not 95%

Step-by-step explanation:

The normal distribution is also known as the Gaussian distribution. About 99.7% of the trees have ages between 10 years and 70 years.

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.

Given that the age of the tree is normally distributed. Also, the following details are known,

Standard Deviation, σ = 10 years

Mean, μ = 40

Now, the z-score and the p-values for the value of 70 and 10 can be written as,

Z = (X-μ)/σ

Z = (70 - 40)/10

Z = 3

The p-value for z-score of 3 is 0.9987.

Z = (X-μ)/σ

Z = (10 - 40)/10

Z = -3

The p-value for z-score of -3 is 0.0013.

Further, the percentage of the trees have ages between 10 years and 70 years is,

Percentage = 0.9987 - 0.0013

                   = 0.9974

                   = 99.7%

Hence, About 99.7% of the trees have ages between 10 years and 70 years.

Answer: 3 weeks

Step-by-step explanation:

We have to note firstly that 12 inches = 1 foot.

The equation given to represent the height in the question, h = 3w + 3.

The number of weeks that it will take the plant to reach one foot will then be:

h = 3w + 3

12 = 3w + 3

3w = 12 - 3

3w = 9

w = 9/3

w = 3

It'll take 3 weeks

Answer:

1793.75 m²

Step-by-step explanation:

Given that :

Total amount of land leased = 2050 m²

Fraction of land given to brother = 1/8

Amount of land given to brother :

1/8 * 2050 = 256.25 m²

Amount of land left :

2050 m² - 256.25 m²

= 1793.75 m²

▶️a = √196

▶️a = 14

▶️ 14² = 14×14

▶️ 14² = 196

hence , 14 is the answer..
