Answer: It is not reasonable. She should have $76
Step-by-step explanation:
If Rachel sold 4 birdhouses for $19 each, the amount that she should have received is:
= 19 * 4 birdhouses
= $76
It is therefore not reasonable that she had only $57 in receipts as she should have $76.

La medida de cada ángulo interno de un polígono regular es 140o. Determine la medida de cada ángulo central.
Answer:
Cada ángulo central tiene una medida de 40°.
Step-by-step explanation:
Un ángulo interno en un polígono regular comprende dos ángulos contiguos de igual medida de dos triángulos contiguos. Si el polígono regular tiene un ángulo interno de 140°, entonces cada triángulo tiene dos ángulos de 70°. El tercer ángulo corresponde al ángulo central. Por Geometría sabemos que la suma de las medidas de los ángulos internos de un triángulo es igual a 180°, entonces tenemos que la medida del ángulo central es:
[tex]\alpha = 180^{\circ} - 70^{\circ} - 70^{\circ}[/tex]
[tex]\alpha = 40^{\circ}[/tex]
Cada ángulo central tiene una medida de 40°.

circular plate had a diameter of 10 cm. The rectangular table it sits on
has dimensions of 5000mm x 3600mm. How many plates can fit on this
table? What is the percentage they cover?
Please help me it’s 10 points also this is my first time on this app
Given :
Dimension of table :
5000 mm * 3600 mm
Area of rectangle = Length * width
Area of table = 5000 * 3600
Area of table = 18000000 mm²
Recall :
1 cm = 10 mm
Diameter of circular plate = 10cm
Converting to mm :
10 * 10 = 100 mm
Area = diameter/ 2 = 100 mm / 2 = 50 mm
Area of a circle = πr²
Area of circular plate = 3.14 * 50² = 7850 mm²
Number of plates = 18000000 / 7850
= 2292.9936 plates
About 2293 plates

a rectangle with a length of 9 inches and a width of 8 inches is divided in to squares of with sides of length 1 inch.One third of these squares are painted red , 1/8 of the remaining squares are painted green, and the others are left unpainted.How many squares are left unpainted?
Answer:
42
Step-by-step explanation:
rectangle = 8x9 = 72
1/3 0f 72 = 24 (72-24= 48)
1/8 of 48 =6 48-6 =42
red-----24
green-----6
unpainted-----42
24+6+42+=72
The 42 squares are left unpainted.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The area of rectangle = 8 x 9 = 72
One-third of these squares are painted red, 1/8 of the remaining squares are painted green, and the others are left unpainted.
1/3 of 72
1/3 x 72 = 24
(72-24= 48)
1/8 of 48
1/8 x 48 = 6
( 48-6 =42)
So,
red = 24
green = 6
unpainted = 42
The 42 squares are left unpainted.

69. A statistics instructor believes that fewer than 20% of Evergreen Valley College (EVC) students attended the opening midnight showing of the latest Harry Potter movie. She surveys 84 of her students and finds that 11 of them attended the midnight showing. The Type I error is to conclude that the percent of EVC students who attended is ________. a. at least 20%, when in fact, it is less than 20%. b. 20%, when in fact, it is 20%. c. less than 20%, when in fact, it is 20%. d. less than 20%, when in fact, it is less than 20%
Answer:
a. at least 20%, when in fact, it is less than 20%.
Step-by-step explanation:
Type 1 Error is to reject null hypothesis when it is actually true.
Here the null hypothesis is fewer than 20% of Evergreen Valley College (EVC) students attended the show.
In mathematics fewer than 20% means less than 20%.
So the null hypothesis is that less than 20 % students attended the show.
We have to reject this hypothesis .
We can reject this hypothesis when we assume that the % is greater than or equal to 20 %
At least 20% means greater than or equal to 20%.
So the best choice is option a.
at least 20%, when in fact, it is less than 20%.

(1 point) Find ⋅ if =⟨−1,0,1⟩ and =⟨4,5,2⟩ Is the angle between the vectors "acute", "obtuse" or "right"?
Answer:
Obtuse.
Step-by-step explanation:
If we have a vector v = (a, b, c)
The magnitude of the vector is:
|v| = √(a^2 + b^2 + c^2)
And the dot product of two vectors:
v = (a, b, c)
w = (c, d, e)
is:
v.w = |v|*|w|*cos(θ) = a*c + b*d + c*e
With that relation, we can find the angle between the two vectors.
In this case, we have:
v = ⟨−1,0,1⟩
then:
|v| = √( (-1)^2 + 0^2 + 1^2) = √2
And:
w = ⟨4,5,2⟩
then:
|w| = √( 4^2 + 5^2 +2^2) = √116
Then:
v.w = (√2)*(√116)*cos(θ) = (-1)*(4) + 0*5 + 1*2
(√2)*(√116)*cos(θ) = -4 + 2 = -2
(15.23)*cos(θ) = -2
cos(θ) = -2/15.23
θ = Acos( -2/15.23) = 97.5°
Then the angle is larger than 90°, so the angle is obtuse.
