A) 180°
B) 90°
C) 130°
D) 50°
Answers
Answer:
D. 50º
Step-by-step explanation:
According to the image below attached, blue lines represents line segments [tex]DB[/tex] and [tex]DB'[/tex], the red line creates a right angle regarding [tex]DB[/tex] (90º), where green line creates a flat angle with the same respect (180º). The angle between [tex]DB[/tex] and [tex]DB'[/tex] is less than 90º and 180º, meaning an acute angle. Therefore, the right answer is D.

of an inch.
in.
The length of one side of the poster is
(Round to the nearest tenth as needed.)
Answers
Answer:
5.48 inches
Step-by-step explanation:
Given that the poster is in the shape of a square.
Area of the square poster = 30 [tex]in^2[/tex]
To find:
The length of side of the poster = ?
Solution:
First of all, let us have a look at the formula for area of a square.
Let the side of square = [tex]x[/tex] inches
Formula:
[tex]Area =Side \times Side[/tex]
Putting the value of the side:
[tex]Area = x\times x\\[/tex]
Putting the value of Area as given in the question statement:
[tex]30 = x^2\\\Rightarrow x =\sqrt{30}\\\Rightarrow \bold{x \approx 5.48\ inches}[/tex]

A rectangular prism has dimensions of 2 cm by 2 cm by 5 cm. What is its surface area? Explain also and thanks if anyone answers my question!
Answers
Answer:
The surface area is 48cm^2
Step-by-step explanation:
Given
Dimension: 2cm by 2cm by 5cm
Shape: Rectangular Prism
Required
Determine its Surface Area (A)
This is calculated as thus:
[tex]A = 2(lw + lh + hw)[/tex]
Where l, w and h are the dimensions of the given shape:
We can say:
[tex]l = length = 2cm[/tex]
[tex]w=width = 2cm[/tex]
[tex]h=height=5cm[/tex]
So:
[tex]A = 2(2 * 2 + 2 * 5 + 5 * 2)[/tex]
[tex]A = 2(4 + 10 + 10)[/tex]
[tex]A = 2(24)[/tex]
[tex]A = 2 * 24[/tex]
[tex]A = 48[/tex]
Hence, the surface area is 48cm^2
Suppose widgit weights produced at Acme Widgit Works have weights that are normally distributed with mean 17.46 grams and variance 375.67 grams. What is the probability that a randomly chosen widgit weighs more then 19 grams?
Answers
Answer:
The probability that a randomly chosen widget weighs more then 19 grams is 0.468.
Step-by-step explanation:
X = Widget weights produced at Acme Widget Works
It is provided that X is normally distributed with mean 17.46 grams and variance 375.67 grams.
Compute the probability that a randomly chosen widget weighs more then 19 grams as follows:
[tex]P(X>19)=P(\frac{X-\mu}{\sqrt{\sigma^{2}}}>\frac{19-17.46}{\sqrt{375.67}})[/tex]
[tex]=P(Z>0.08)\\\\=1-P(Z<0.08)\\\\=1-0.53188\\\\=0.46812\\\\\approx 0.468[/tex]
Thus, the probability that a randomly chosen widget weighs more then 19 grams is 0.468.

What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that, A community garden contains five types of plants. Two types are flowers: roses and daisies. The other three types are vegetable plants: cucumbers, bell peppers, and green beans.
Since the number of the Daisly plant and the rose is 2 and 4 respectively, its ratio is,
=Daisy plant: rose
=2:4
=1:2
Thus, it is accurate to say that there are 2:1 daisies to rose plants. Because the Daisy plant and the Rose have the numbers 2 and 4, respectively

Answers
Answer:
The x-intercept is (-6, 0) and the y-intercept is (0, 2)
Step-by-step explanation:
We are already given points where x = 0 and y = 0
The x-intercept is when y = 0
The y-intercept is when x = 0
So the x-intercept is (-6, 0)
and the y-intercept is (0, 2)

3/10 = x or 0.3 = x
Step-by-step explanation:
2.1 / x + 1 4/5 = 3 / 10x
1. first cross multiply and solve it normally:
3 (x + 1 4/5) = (2.1) 10x
3x + 5 2/5 = 21x
-3x -3x
5 2/5 = 18x
3/10 = x or 0.3 = x
these questions are kind annoying to solve because of the fractions, so if you can, use a calculator to solve them! its much easier!
hope this helps!
Answer:
x = 3/10 = 0.3
Step-by-step explanation:
{(2.1)/(x+1 4/5)} = 3/10x
x + 1 4/5 = x + 5/5 + 4/5 = x + 9/5
then:
(2.1)/(x+9/5) = 3/10x
10x*2.1 = 3(x+9/5)
21x = 3x+ 27/5
21x - 3x = 27/5
18x = 27/5
90x/5 = 27/5
90x = 27
x = 27/90
x = 3/10 = 0.3
