As Sum of the Three Angles in a Triangle = 180°

We can write as :

Angle (1) + 40° + 90° = 180°

Angle (1) + 130° = 180°

Angle (1) = 180° - 130°

Angle (1) = 50°

As Angle (2) and 90° are Vertically opposite Angles :

Angle (2) should be Equal to 90°

Angle (2) = 90°

Angle (2) + Angle (3) + 30° = 180°

90° + Angle (3) = 30° = 180°

Angle(3) + 120° = 180°

Angle(3) = 180° - 120°

Angle(3) = 60°

As Angle (3) and Angle(4) are Vertically opposite Angles :

Angle (4) should be Equal to Angle(3)

Angle (4) = 60°

Angle(4) + Angle(5) + 60° = 180°

60° + Angle(5) + 60° = 180°

Angle(5) + 120° = 180°

Angle(5) = 180° - 120°

Angle(5) = 60°

As Angle (5) and Angle(6) are Vertically opposite Angles :

Angle (6) should be Equal to Angle(5)

Angle (6) = 60°

Angle(6) + Angle(7) + 20° = 180°

60° + Angle(7) + 20° = 180°

Angle(7) + 80° = 180°

Angle(7) = 180° - 80°

Angle(7) = 100°

I am confused on this question

<h3>Answer:  Around 4681 grills</h3>

============================================

Explanation:

x = number of years

y = number of grills sold

The equation we'll use is the exponential equation y = 3300(1.06)^x

The 3300 of course is the initial amount sold. The 1.06 as the base indicates that the sales increase by 6% each year. Think of it the 1.06 as 1+0.06 = 100% + 6%

If we plugged x = 0 into that equation, then we get

y = 3300(1.06)^x = 3300(1.06)^0 = 3300

which helps confirm the correct equation.

----------------

Now plug in x = 6 to find the sales for year 6.

y = 3300(1.06)^x = 3300(1.06)^6 \approx 4681.11 \approx 4681

The projected sales for year 6 are about 4681 grills. This is an estimate based on the assumption that the sales will increase by 6% each year. Of course, the reality is that things aren't always so simple like this (but it should give a fairly good idea of what's going on).

Suppose that IQ scores have a bell-shaped distribution with a mean of
Svetllana [295]

Answer:

68 %

Step-by-step explanation:

The Empirical rule formula states that:

• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

Mean of 96 and a Standard deviation of 17

Applying , the first empirical rule for 1 standard deviation from the mean, we have:

μ - σ

96 - 17

= 79

μ + σ

96 + 17

= 113

Therefore, the percentage of IQ scores that are between 79 and 113 is 68%

Given the following equation, determine the solutions when y=0 for the function: y=(x+4)(x-3)
AysviL [449]

Answer:

x=-4 and x=3

Step-by-step explanation:

If y=0, then we use the Zero Product Property:

0=(x+4)(x-3)

x+4=0

x=-4

x-3=0

x=3

Find the area <br> Please someone help
IgorLugansk [536]
So first let’s find the area of the rectangle. The formula for finding the area of a rectangle is A=l x w.
The length is 10ft and the width is 8ft.
A=10ft x 8ft=80ft^2
The area of the rectangle is 80ft^2.

Now let’s find the area of the triangle. The formula for finding the area of a triangle is A=h x b/2. Both the height and the base of the triangle is 4ft.
A=4ft x 4ft/2=8ft^2.
The area of the triangle is 8ft^2.

Now to find the area of the entire shape. Add the area of the rectangle and the area of the triangle.
80ft^2+8ft^2=88ft^2
The total area of the shape is 88ft^2.
