The altitude of the trapezoid is approximately 2.5 cm.

Here, we have,

To find the altitude of the trapezoid, we can use the formula for the area of a trapezoid:

Area = (1/2) * (sum of the bases) * altitude

Given that

one base (a) is 1 cm, the other base (b) is 5 cm, and the area is 7.5 cm², we can plug these values into the formula and solve for the altitude:

7.5 cm² = (1/2) * (1 cm + 5 cm) * altitude

Simplifying:

7.5 cm² = (1/2) * 6 cm * altitude

7.5 cm² = 3 cm * altitude

Now, we can isolate the altitude by dividing both sides of the equation by 3 cm:

altitude = 7.5 cm² / 3 cm

altitude ≈ 2.5 cm

Therefore, the altitude of the trapezoid is approximately 2.5 cm.

Answer:

155 Degrees

Step-by-step :

(Time x Rate of Temp) + Initial Temp = Final Temperature

Ex. (6 * 15) + 65 = 155 Degrees

Answer:

The temperature of the oven 6 minutes after being turned on is 155°

The temperature of the oven t minutes after being turned on is 15t + 65

Step-by-step explanation:

y=mx + b

y = y coordinate

m = slope

x = x coordinate

b = y intercept

The y intercept is when x = 0, so the initial temperature

b = 65°

The slope is increase at a rate of per minute after being turned on.

m = 15°

The y coordinate will represent the temperature of the oven after a certain amount of minutes after being turned on

y

The x coordinate will represent the amount of minutes after the oven being turn on

x = t

combine:

What is the temperature of the oven tt minutes after being turned on?

y = 15t + 65

What is the temperature of the oven 6 minutes after being turned on?

t = 6 minutes

y = 15t + 65

y = 15(6) + 65

y = 90 + 65

y = 155

Formulas

d1 = 20 + 50*t                       This is dump truck #1

d2 = 70*t                               This is dump truck #2

d1 = d2                                  This is given in the problem

Solution

if d1 = d2 then you get 20+50t = 70t as your working equation.

20 + 50t = 70t                        Subtract 50t from both sides

20 +50t-50t = 70t-50t           Combine

20 = 20t                                  Divide both sides by 20

20/20 = 20t/20

Answer:

Imaginary Roots

Step-by-step explanation:

The quadratic equation ax^2 + bx + c = 0 is written in standard form, and the formula is

x = [-b ± √(b^2 - 4ac)]/ 2a

Given:

3x2 - 4x + 5 = 0'

Here a = 3, b = -4 and c = 5

Substituting:

x = [-(-4) ± √((-4)2 - 4 × 3 × 5)]/ (2 × 3)

Further Simplification:
x = [4 ± √(16 - 60)]/6                 ----> Discriminant: b^2 - 4ac = -44 < 0.

x = [4 ± √-44]/ 6

Now, we get:

x = [4 ± 2√-11]/ 6

x = [2 ± i √11]/ 3

Therefore, The best description of the roots of the equation 3x2 - 4x + 5 = 0 is imaginary roots.

Answer:

x = 9

Step-by-step explanation:

When 1 is divided by 9, we understand it is a non-terminating decimal number because the denominator consists of other number other than 2 and 5.

Now, let's get into how to solve for x :

Divide both sides by .111... :

1/.111... x .111... = 1/.111 x 1/x

1 = 1/(x)(.111....)

Multiply both sides by x :

1(x) = (x)/(x)(.111...)

x = 1/.111...

x = 9 (nearest whole number)

Answer:

[tex]\sf 0.\dot{1}=\dfrac{1}{9}[/tex]

Therefore, x = 9

Step-by-step explanation:

To convert 0.11111... to a fraction:

Equation 1

Let:   y = 0.11111...

Equation 2

Multiply both sides by 10:

⇒ y · 10 = 0.11111... · 10

⇒ 10y = 1.11111...

Subtract Equation 1 from Equation 2 to eliminate the recurring digits after the decimal:

⇒ 10y - y = 1.1111... - 0.11111...

⇒ 9y = 1

Divide both sides by 9

[tex]\implies \sf y=\dfrac{1}{9}[/tex]

Therefore,

[tex]\sf 0.\dot{1}=\dfrac{1}{9}[/tex]

So if:

[tex]\sf 0.\dot{1}=\dfrac{1}{x}[/tex]

Huw's answer of 9 days is incorrect because more guests would finish the food in less time so the number of days for 30 guests is less than 6 days.

The number of days that the food can last 30 guests is 4 days.

More guests would eat the food faster which means that it would be finished in less days than the 6 days used by 20 guests.

To find the days the food would last 30 guests, use the inverse proportion formula:
= (Number of guests x Number of days food lasts for guests) / New number of guests

= (20 x 6) / 30

= 4 days

A triangle is a three-edged polygon with three vertices. The length of the sides of the triangle is 5, 5, and 5√2.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

Since the two angles are equal, therefore, the length of the two legs of the isosceles right triangle will be equal and will be less than the hypothenuse.

Hence, the length of the sides of the triangle is 5, 5, and 5√2.

Answer:

The way is in the steps.

Step-by-step explanation:

y = sin(x) has a period of 2π and amplitude of 1.

a) y = a * sin b(x - c) - d

y = 7/2 * sin 2/3(x - π/4) - 2

b) amplitude is affected by a = 7/2 , so the amplitude is 7/2.

The range is (-5.5 , 1.5) because looking at the graph, but also by making a table to help find the range.

c) Period = 2π/b

Period = 2π/2/3 = 3π

d) Horizontal Shift left/right is dependent on c.

c = π/4 , so Horizontal Shift to the Right by π/4

Vertical Shift up/down is dependent on d.

d = -2 , so Vertical down shift by 2.
