The courtyard behind Jennie’s house is shaped like a trapezoid the bases measure 8 meters and 11 meters the height of the trapezoid is 12 meters what is the area of the courtyard

Answers

The area of the trapezoidal courtyard is 114 square meters.

To find the area of a trapezoid, you can use the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times (\text{sum of the bases}) \times \text{height} \][/tex]

Given:

- Base 1 (b1) = 8 meters

- Base 2 (b2) = 11 meters

- Height (h) = 12 meters

Plugging these values into the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times (8 + 11) \times 12 \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times 19 \times 12 \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times 228 \][/tex]

[tex]\[ \text{Area} = 114 \][/tex]

So, the area of the courtyard is 114 square meters.

Answers

Answer:

[tex]x=53[/tex]

Step-by-step explanation:

step 1

Find the measure of arc DF

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<OEF=\frac{1}{2}(arc\ DF)[/tex]

we have

[tex]m<OEF=32\°[/tex]

substitute

[tex]32\°=\frac{1}{2}(arc\ DF)[/tex]

[tex]arc\ DF=64\°[/tex]

step 2

Find the measure of x

we know that

[tex]arc\ DF+arc\ EF=180\°[/tex] ---> is half the circle

we have

[tex]arc\ DF=64\°[/tex]

[tex]arc\ EF=(2x+10)\°[/tex]

substitute

[tex]64\°+(2x+10)\°=180\°[/tex]

[tex]2x\°=180\°-74\°[/tex]

[tex]2x\°=106\°[/tex]

[tex]x=53[/tex]

The value of x for the angles of the inscribed circle is gotten as; x = 53°

What is the value of the angle in the circle?

Let us first find the angle subtended by the arc DF

From inscribed angle theorem, we know that the measure of an inscribed angle is half the measure of the intercepted arc. Thus;

m∠EOF = ¹/₂(arc DF)

Thus;

¹/₂(arc DF) = 32°

arc DF = 64°

From half circle theorem, we can say that;

arc DF + arc EF = 180°

Thus;

64 + 2x + 10 = 180

2x = 180 - 74

2x = 106

x = 53°

julie,ellen, and jenny shared a pizza. julia ate 1/8 of the pizza Ellen and Jenny ate 3/8 of pizza Did they eat whole pizza​

Answers

Julia ate 1/8

Ellen and Jenny ate 3/8

1/8 + 3/8 = 4/8

No they didn't eat the whole pizza, they only ate half of the pizza.

Julie, Ellen, and Jenny together ate [tex]\frac{1}{8}[/tex]+ [tex]\frac{3}{8}[/tex] = [tex]\frac{4}{8}[/tex] or [tex]\frac{1}{2}[/tex]of the pizza, which means they ate only half of it, not the entire pizza.

The question involves the mathematical concept of fractions and their addition. Julie ate [tex]\frac{1}{8}[/tex] of the pizza, while Ellen and Jenny together ate [tex]\frac{3}{8}[/tex]of the pizza. To determine if they ate the whole pizza, we need to add these fractions.

[tex]\frac{1}{8}[/tex] (Julie's portion) + [tex]\frac{3}{8}[/tex] (Ellen and Jenny's portion) =  [tex]\frac{4}{8}[/tex]or [tex]\frac{1}{2}[/tex] after simplifying.

Since [tex]\frac{1}{2}[/tex] is less than a whole, Julie, Ellen, and Jenny did not eat the entire pizza. They ate only half of it.

In 1995, Orlando, Florida, was about 175,000. At that time, the population was growing
at a rate of about 2000 per year.
i. Write an equation, in slope-intercept form to find Orlando’s population for any
year.
ii. What is Orlando’s population in 2010?

Answers

To model Orlando's population growth, an equation in slope-intercept form is y = 2000x + 175000. The year 2010 is 15 years after 1995, so substituting 15 in for x gives a population of approximately 205,000 residents for Orlando in 2010.

To answer the student's question, first we need to write an equation in slope-intercept form to find Orlando's population for any year. The slope-intercept form of a line is given by the equation y = mx + b, where m is the slope of the line (the rate of change) and b is the y-intercept (the starting value when x=0). In this case, the variable y represents Orlando's population, m represents the annual growth rate (2000 people per year), and x represents the number of years since 1995.

Using these variables, our equation becomes y = 2000x + 175000, where x is the number of years since 1995. To find Orlando's population in 2010, we must substitute x with 15, since 2010 is 15 years after 1995.

The calculation would be: y = 2000(15) + 175000, which simplifies to y = 205000.

Therefore, Orlando's population in 2010 was approximately 205,000 residents.

The base edge of a square pyramid is 30 cm. The pyramid is 6 cm tall. Find the volume of the pyramid

Answers

Answer:

5400 cm^3

Step-by-step explanation:

Volume = Base Area * H

Base area is the area of a square with one side = 30 cm

H = 6cm

Base Area = s^2

Base Area = 30^2 = 900

Volume  =  900 * 6

Volume = 5400 cm^3

Answer:

1800 cm³

Step-by-step explanation:

Recall that the formula for the area of a square is A = s², where s is the side length.

Here, that area is A = (30 cm)²2.

The formula for the volume of a square pyramid is:

V = (1/3)(base area)(height)

   = (1/3)(30 cm)²2*(6 cm)

   = (1/3)(900 cm²)(6 cm) = 1800 cm³

The volume of this pyramid is 1800 cm³.

Match each function

Answers

Answer:

* The degree of the function is 4 and the leading coefficient is positive

 f(x) = (x + 6)(2x - 3)(x - 1)²

* The degree of the function is 5 and the leading coefficient is negative

 f(x) = (x - 2)²(-2x - 1)²(-x + 1)

* The degree of the function is 6 and the leading coefficient is negative

 f(x) = (-x + 1)³(x + 2)²(x - 3)

* The degree of the function is 5 and the leading coefficient is positive

 f(x) = (-2x + 1)²(x - 3)²(x + 1)

Step-by-step explanation:

∵ f(x) = (x + 6)(2x - 3)(x - 1)²

∵  (x)(2x)(x²) = 2x^4

∴ The degree of the function is 4

∴ The leading coefficient is positive ⇒ (2)

∵ f(x) = (x - 2)²(-2x - 1)²(-x + 1)

∵ (x)²(-2x)²(-x) = (x²)(4x²)(-x) = -4x^5 ⇒ (neglect -ve with even power)

∴ The degree of the function is 5

∴ The leading coefficient is negative ⇒ (-4)

∵ f(x) = (-x + 1)³(x + 2)²(x - 3)

∵ (-x)³(x)²(x) = (-x³)(x²)(x) = -x^6

∴ The degree of the function is 6

∴ The leading coefficient is negative ⇒ (-1)

∵ f(x) = (-2x + 1)²(x - 3)²(x + 1)

∵ (-2x)²(x)²(x) = (4x²)(x²)(x) = 4x^5

∴ The degree of the function is 5

∴ The leading coefficient is positive ⇒ (4)

What is the nth term of the arithmetic sequence 7,5,3,1?

Answers

Answer:

tn = 7 + (n - 1)*(-2) or

tn = 9 - 2n

Step-by-step explanation:

You are (beginning with 7) subtracting 2 from the term to the left.

a = 7

d = -2

tn = a1 + (n - 1)*d

tn = 7 + (n - 1)*(-2)

Try this out on n = 4

t4 = 7 + (4 - 1)*-2

t4 = 7 +  (3) (-2)

t4 = 7 - 6

t4 = 1 just as it says.

More generally

tn = 7 + (n - 1)*-2

tn = 7 + (-2n) + 2

tn = 9 - 2n

The following frequency table summarizes the number of children that dads in Dads Club have.
Based on this data, what is a reasonable estimate of the probability that the next dad to join Dads Club has fewer than 3 children?

Now there are 6+4+8+1+1=20 dads in the Dads Club.

Fewer than 3 children have

1 child - 6 dads2 children - 4 dads.

So, 6+4=10 dads have fewer than 3 children.

The probability that the dad of Dads Club has fewer than 3 children is

[tex]Pr=\dfrac{10}{20}=0.5 \text{ or } 50\%.[/tex]

The probability that the next dad to join Dads Club has fewer than 3 children is reasonable to be 50%.

Answer:

Option: C is the correct answer.

           C.  50%

Step-by-step explanation:

Let P denotes the probability of an event.

and A denote the event that the next dad has fewer than 3 children.

From the table the total number of dads are: 6+4+8+1+1=20

The number of dad who have less than 3 children are: 6+4=10

Hence, we have

[tex]P(A)=\dfrac{\text{Number\ of\ dad\ with\ less\ than\ 3\ children}}{\text{Total\ number\ of dad}}[/tex]

Hence, we have:

[tex]P(A)=\dfrac{10}{20}=\dfrac{1}{2}[/tex]
