Someone help me solve these two please !!

Given:

Trapezoid with bases 10 and 20, and height of the trapezoid is 6.

To find:

The area of the trapezoid.

Solution:

We know that the area of a trapezoid is:

[tex]A=\dfrac{1}{2}h(b_1+b_2)[/tex]

Where, h is the height of the trapezoid and [tex]b_1,b_2[/tex] are bases of the trapezoid.

Putting [tex]h=6, b_1=10,b_2=20[/tex] in the above formula, we get

[tex]A=\dfrac{1}{2}(6)(10+20)[/tex]

[tex]A=3(30)[/tex]

[tex]A=90[/tex]

The area of the trapezoid is 90 sq units. Therefore, the correct option is A.

Answer:

"The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0."

Step-by-step explanation:

Follow PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, multiply 7 and 2 together:

4 + 7 x 2 - 8 =

4 + (7 x 2) - 8 =

4 + 14 - 8

Next, follow the left-> right rule. Add, then subtract:

(4 + 14) - 8

(18) - 8 = 10

10 is your answer.

Answer:

[tex]Surface \ area = 2 (LB + BH + HL) = 2 ((4\times 8)+(8 \times 6) + (6 \times 4))[/tex]

                                                     [tex]= 2(32 + 48 + 24)\\=2(104) \\=208 cm^2[/tex]

[tex]Volume = L \times B \times H = 4 \times 8 \times 6 = 192cm^3[/tex]

Answer:

The area is 64squared units

Step-by-step explanation:

Given

[tex]E = (4,4)[/tex]

[tex]F = (-4,4)[/tex]

[tex]G = (-4,-4)[/tex]

[tex]H = (4,-4)[/tex]

Required

The area of the polygon

First, we plot the given coordinates on a plane (See attachment)

From the attachment, we can see that the 4 coordinates make up a square.

Where

[tex]EF = FG = GH = GE = 8\ units[/tex]

So, the area is:

[tex]Area = EF^2[/tex]

Substitute [tex]8[/tex] for [tex]EF[/tex]

[tex]Area = 8^2[/tex]

[tex]Area = 64[/tex]

Hence, the area is 64 squared units

Step-by-step explanation:

Answer:

The 95% confidence interval to determine the true proportion of all patrons who would be interested in attending the showing is (0.2121, 0.4671).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

Of the 53 patrons, 18 said that they would come to see the film.

This means that [tex]n = 53, \pi = \frac{18}{53} = 0.3396[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3396 - 1.96\sqrt{\frac{0.3396*0.6604}{53}} = 0.2121[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3396 + 1.96\sqrt{\frac{0.3396*0.6604}{53}} = 0.4671[/tex]

The 95% confidence interval to determine the true proportion of all patrons who would be interested in attending the showing is (0.2121, 0.4671).

Answer:

m<HJK = 40°

Step-by-step explanation:

Given:

m<HJK = 3x - 2

m<KJL = 50°

Required:

m<HJK

Solution:

m<HJK + m<KJL = 90° (complementary angle)

Substitute

3x - 2 + 50 = 90

Add like terms

3x + 48 = 90

3x + 48 - 48 = 90 - 48

3x = 42

3x/3 = 42/3

x = 14

✅m<HJK = 3x - 2

Plug in the value of x

m<HJK = 3(14) - 2 = 42 - 2

m<HJK = 40°

Answer:

82

Step-by-step explanation:

you multiply 4(25)

which is 100

and then (9)2

which is 18

and then subtract 18 from 100

which gives you 82

Answer:

  (x, y) = (-11, 4)

Step-by-step explanation:

You can subtract 3 times the second equation from the first to eliminate y.

  (7x +9y) -3(x +3y) = (-41) -3(1)

  4x = -44

  x = -11

Substituting into the second equation gives ...

  -11 +3y = 1

  3y = 12

  y = 4

The solution is (x, y) = (-11, 4).

Answer:

105.12 feets

Step-by-step explanation:

From the figure x we can identify a rectangle and a semicircle :

Area of rectangle = Length * width

Area = 8 * 10 = 80 feet²

The Area of a semicircle = 1/2πr²

Radius, r = 8 /2 = 4 feets

A = 1/2 * 3.14 * 4²

A = 3.14 * 8

A = 25.12 feet²

Area of figure = 80 + 25.12 = 105.12 feets

x > 2

Step-by-step explanation:

x + 1 > 3

Subtract 1 from both sides

x > 2

Answer:

15x + 190 >= 400

* >= means greater than or equal to *

at least 14 friends

Step-by-step explanation:

without the inequality it'd be 15x + 190 = 400

but since you want it to be at least 400 you change the = to the greater than or equal to sign

15x + 190 = 400 * subtract 190 from both sides*

15x = 210 *divide both sides by 15*

x = 14
