Answer:
A. 1.5 cm by 2.5 cm
B. 27 cm by 45 cm
C. 9 cm by 15 cm
D. 30 cm by 50 cm
Step-by-step explanation:
The dimensions of the original painting = 12 cm by 20 cm painting
Hence, the proportion is:
12/20 = 0.6
Hence, we compare the options given in the question.
A. 1.5 cm by 2.5 cm
= 1.5/2.5 = 0.6 , option A is correct
B. 27 cm by 45 cm
27cm/45 cm = 0.6 Option B is correct
C. 9 cm by 15 cm
9cm/15cm = 0.6 , Option C is correct
D. 30 cm by 50 cm
30 cm /50 cm = 0.6 Option D is correct
E. 6 cm by 14 cm
6cm/14 cm = 0.4285714286
Option E is not correct
Therefore, Options A to D are the correct options
What is the value of the sin3x/6x; as x approaches to zero
Step-by-step explanation:
When x = 0,
sin3x / 6x = 0 / 0, which is an indeterminate form.
Hence we use L'Hospital's rule:
d/dx (sin3x) = 3cos3x
d/dx (6x) = 6
Now we have 3cos3x / 6 or 0.5cos3x.
When x = 0, 0.5cos3x = 0.5(1) = 0.5.
Hence the limit is 0.5.
Using limits, it is found that the value of the function is of 0.5.
The limit given is:
[tex]\lim_{x \rightarrow 0} \frac{\sin{(3x)}}{6x}[/tex]
The following property is used:
[tex]\lim_{x \rightarrow 0} \frac{\sin{(ax)}}{ax} = 1[/tex]
Hence, multiplying the numerator and denominator by 0.5:
[tex]\lim_{x \rightarrow 0} \frac{\sin{(3x)}}{6x} = 0.5\lim_{x \rightarrow 0} \frac{\sin{(3x)}}{3x} = 0.5(1) = 0.5[/tex]
The value of the function is of 0.5.

Two step problem: Aaron can type 40 words per minute. Jessica can type 55 words per minute. If Aaron and Jessica each type for 30 minutes, how many more words will Jessica type than Aaron?
Answer:
Step-by-step explanation:
Aaron types 40 wpm times 30 minutes = 1200 wpm.
Jessica types 55 wpm times 30 minutes = 1650 wpm.
Jessica’s types 450 more words per minute than Aaron.
A= 450 more than Aaron

For every odd-degree polynomial function,
When x approaches positive infinity, y approaches positive infinity.
When x approaches negative infinity, y approaches negative infinity.
As shown in the graph, substituting x into any numbers that are greater than 3 and you'll see how the graph heads toward y-value infinitely.
A tv has a screen that is 15 in long and has a 25 in long diagonal find the area of the tv screen?
Answer:
300 in²
Step-by-step explanation:
The TV screen is rectangular in shape.
Thus:
Length of the rectangular screen = 15 in.
Diagonal of the rectangular screen = 25 in.
To find the area of the rectangular screen, we need the length and the width of the screen.
Use pythagorean theorem to find the width as shown below:
[tex] a^2 + b^2 = c^2 [/tex], where:
a = width = ?
b = 15 in.
c = 25 in. (The hypotenuse/longest side)
Plug in the values into the equation
[tex] a^2 + 225 = 625 [/tex]
Subtract 225 from each side
[tex] a^2 = 400 [/tex]
Take the square root of both sides
[tex] a = 20 [/tex]
width of the screen = 20 in.
Thus,
Area of the screen = length × width
= 15 × 20
Area = 300 in²
What is 9m + 6 = 87
please help im desperate fwhe
Answer:
m=9
Step-by-step explanation:
9m=81
Answer:
9
Step-by-step explanation:
First you have to get the variable by its self (m). So you will get rid of 6 and since it’s positive you will do negative 6 to cancel it out. But what you do to one side you do to the other, so you will do 87 - 6 and get 81. Now it’s 9m = 81. So then since 9 is next to m that implies multiplcation so you do the opposite of multiplication and dived 9 by both sides. And when you do that you get 9.

A school is taking a group of students on a field trip to the aquarium. Including chaperones, 132 people will be going on the field trip. Found out it's 110 students. The ratio of shark bookmarks to seal bookmarks to the students is 3:2. How many students receive shark bookmarks?
Given:
Total people = 132
Total students = 110
The ratio of shark bookmarks to seal bookmarks to the students is 3:2.
To find:
The number of students who receive shark bookmarks.
Solution:
Let the total number of students who receive shark bookmarks be 3x and number of students who receive seal bookmarks be 2x.
Total number of students is 110. So,
[tex]3x+2x=110[/tex]
[tex]5x=110[/tex]
Divide both sides by 5.
[tex]x=22[/tex]
Now,
Number of students who receive shark bookmarks [tex]=3x[/tex]
[tex]=3(22)[/tex]
[tex]=66[/tex]
Therefore, 66 students receive shark bookmarks.

An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7.
Which lengths make sense for possible values of b? Check all that apply.
–2 in.
0 in.
0.5 in.
2 in.
7.9 in.
Answer:
0.5 in, 2 in
Step-by-step explanation:
It cannot be a negative number, so -2 is out.If we use Pythagorean's theorem ([tex]a^2+b^2=c^2[/tex]), we know that only 0.5 and 2 are correct values of b.
