Answer:

286

Step-by-step explanation:

The equation for Area of Trapezoid is:

[tex]Atrapezoid = \frac{h(b1+b2)}{2}[/tex]

First, replace the variables with their values:

h=13

b1=15

b2=(7+7)+15=29

Now, your equation should look like this:

[tex]Atrapezoid = \frac{13(15+29)}{2}[/tex]

Now, solve:

[tex]15+29=44[/tex]

↓

[tex]\frac{13(44)}{2}[/tex]

↓

[tex]44*13=572[/tex]

↓

[tex]\frac{572}{2}=286[/tex]

The area of the trapezoid is 286.

it has an infinite (many many)solutions. For example a function rule for g(x) could be g(x)=3x2+7 or g(x)=sin(x) and so on.

The correct options are (A) up and (A) 2 units to the left of the function g(x)

Step-by-step explanation:  We are given the following functions:

We know that the vertex form of a function h(x) is

The function h(x) opens down if a < 0 and opens up if a > 0.

Substituting the value of g(x) from equation (i) in (ii), we have

Comparing it with the vertex form, we get

a = 1 > 0.

So, f(x) opens up.

Also, the value of 'x' co-ordinate in f(x) is increased by 2 units as compared to g(x), so the graph of g(x) is shifted horizontally 2 units to the left of the function g(x).

The graphs of both the functions f(x) and g(x) are attached below.

Thus, the graph of function f(x) opens (A). up

and

the graph of the function f(x) is shifted horizontally (A). 2 units to the left of the function g(x).

Answer: See below

Step-by-step explanation:

a) 6(3x+4y-8)

Use the distributive property:

6*3x + 6*4y - 6*8

18x + 24y - 48

So D is the correct answer

b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.

12+4x

= 4(3+x)

So D is the correct answer

c) When you expand both C and D and simplify, you get 16x+36 as solution

d) 14x+2y+10z

Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times

14x+2y+10z

= 2(7x+y+5z)

So D is the correct answer again ;)

Answer:

glass A holds more

the glass holds 39.8 cubic centimeters more than the other glass

Step-by-step explanation:

1. π x 4 to the power of 2 x 8/3 = 134.0412866

2. π x 3 to the power of 2 x 10/3 = 94.24777961

3. 134.0412866 - 94.24777961 = 39.79350699

4. 39.79350699 rounded to the nearest tenth is 39.8

Glass A holds more liquid and the glass hold 40 cm³ more liquid than glass B.

The study of geometric figure calculation and its parameters, such as area, length, volume, lateral surface area, surface area, and so on, is known as mensuration. It discusses all of the essential equations and properties of various geometric shapes and figures, as well as the fundamentals of calculation.

Given two glass and the inside of each glass is shaped like a cone

for glass A, height  = 8 cm and radius = 4 cm

for glass B,  height = 10cm and radius = 3 cm

to find the capacity of both glasses we need to find the volume of the both glass

volume of cone =  V=1/3hπr², where h = height and r = radius

volume of glass A = 1/3 x 8 x π x 4²

volume of glass A = 133.97 cm³

volume of glass B = 1/3 x 10 x π x 3²

volume of glass B = 94.2 cm³

volume of A - volume of glass B = 133.97 - 94.2 = 39.77 cm³

Hence the volume of glass A is more then Glass B so glass A contain more liquid than glass B and the glass holds 40 cubic centimeters (nearest tenth) more than the other glass.

Step-by-step explanation:

All the possible values for the number are [tex]x=2+2i\sqrt{3}[/tex] and [tex]x=2-2i\sqrt{3}[/tex].

Given that, a number plus 16 times its reciprocal equals 4.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

Let the unknown number be x.

Now, the equation is [tex]x+\frac{16}{x}=4[/tex]

[tex]\frac{x^2+6}{x}=4[/tex]

[tex]x^2+16=4x[/tex]

[tex]x^2-4x+16=0[/tex]

By comparing [tex]x^2-4x+16=0[/tex] with [tex]ax^2+bx+c=0[/tex], we get a=1, b=-4 and c=16.

Substitute these values in quadratic formula [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex], we get

[tex]x=\frac{4\pm\sqrt{(-4)^2-4\times1\times16} }{2\times1}[/tex]

[tex]x=\frac{4\pm\sqrt{-48} }{2}[/tex]

[tex]x=\frac{4\pm4i\sqrt{3} }{2}[/tex]

[tex]x=2+2i\sqrt{3}[/tex] and [tex]x=2-2i\sqrt{3}[/tex]

Therefore, all the possible values for the number are [tex]x=2+2i\sqrt{3}[/tex] and [tex]x=2-2i\sqrt{3}[/tex].

You need to find all the people who read more than three hours. More than three hours would mean people who read more than 4, 5, or 6 hours. Since the number of people who read 4 hours is 6 dots and 5 hours are 3 dots, we add them together.

6+3

= 9

Since the number of people who read 6 hours is 5, we also add that.

9+5

= 14

Answer:

14

Step-by-step explanation:

More than 3 hours would be 4 hours and 5 hours and 6 hours.

So sum the number of dots above the numbers 4, 5 and 6:

Answer:

the third one

Step-by-step explanation:

upside down t

Answer:

See below

Step-by-step explanation:

(7x +3) is the same as angle opposite B

So 7x+3 will equal 103 degrees.

To figure out angle ACB we just take a straight line (180 degrees) and minue 103, which gives us 77 degrees

ACB = 77 degrees

Now we will just isolate x so we can figure out it's value for angle CAB

7x = 103 - 3

7x = 100

x = 100/7

x = roughly 14.3

CAB = 3x - 10 = (14.3 * 3) - 10

= 43 - 10

CAB = 33 degrees

The measure of ∠CAB is 43°.

The measure of ∠ACB  is 80°.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

From the figure,

ΔABC

∠A + ∠B + ∠C = 180 ______(A)

And,

∠C = 7x + 3 [ alternate angles ] _____(1)

∠B = 180 - 103 = 77 [ straight angle ] _____(2)

∠A = 3x - 10 _____(3)

Substituting (1), (2), and (3) in (A).

∠A + ∠B + ∠C = 180

7x + 3 + 77 + 3x - 10 = 180

10x + 80 - 10 = 180

10x + 70 = 180

10x = 180 - 70

10x = 110

x = 110/10

x = 11

Now,

∠CAB = 3x + 10

∠ACB = 7x + 3 [ alternate angle with (7x + 3)

Substituting x = 11.

∠CAB = 3 x 11 + 10 = 33 + 10 = 43

∠ACB = 7 x 11 + 3  = 77 + 3 = 80

Thus,

∠CAB = 43

∠ACB = 80
