Mona needs to photocopy a 14.5 centimeters wide by 15 centimeters long picture. She wants to enlarge the picture so that its length will be
37.5 centimeters. How wide will the enlarged picture be?
O a
38.8 cm
Ob
37 cm
ос
93.75 cm
Od
36.25 cm
Answer:
The enlarged picture will have a width of 35.8 cm
Step-by-step explanation:
We can solve this question by proportions, using rule of three.
When the length is of 15 centimeters, the width will be of 14.5 centimeters. What is the width when the length is 37 centimeters?
15 cm - 14.5 cm
37 cm - x
Applying cross multiplication
[tex]15x = 14.5*37[/tex]
[tex]x = \frac{14.5*37}{15}[/tex]
[tex]x = 35.8[/tex]
The enlarged picture will have a width of 35.8 cm
Answer:
36.25 cm
Step-by-step explanation:
37.5 divided by 15 is 2.5 then multiply 14.5 by 2.5 and your answer will be 36.25 cm.

Which statement about the simplified binomial expansion of (a – b)n, where n is a positive integer, is true?
Answer:
A on Edge 2021 ;))
Step-by-step explanation:
All terms of the expansion are positive.
The true statement is all terms of the expansion are positive.
What are binomial expansions?Binomial expansions are expansions of expressions that have two terms
The expression is given as:
[tex](a - b)^n[/tex]
This means that the expression (a - b) is to be multiplied by itself, n times.
Hence, all terms of the expansion are positive.

Find the output, g, when the input, r, is 4.
g=25−3r
plzzzzzz help me i need to finish
Answer: g = 13 / Thats the output
Step-by-step explanation:
g = 25 - 3r
Its telling you the r is 4 since its the input.
g = 25 - 3 ( 4 ) see!! just plug in the number
Now Solve
g = 25 - 12
g = 13
Answer:
g = 13
Step-by-step explanation:
since r = 4, you make the equation :
g=25-3(4)
first you multiply 3 and 4 and you get 12
g=25-12
and 25 - 12 is 13 which equals :
g = 13

The linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)
What is linear factor?The linear factors of polynomials are the first-degree equations that act as the building block for the simple or complex higher-order polynomials.
Given that, a polynomial 2x⁴+13³+27x²+13x-15, the remainder upon division with x²+4x +5 is zero,
That means, x²+4x +5 is a factor of the given polynomial,
On diving 2x⁴+13³+27x²+13x-15 by x²+4x +5 we get 2x²+5x+3 as quotient that means, x²+4x +5 and 2x²+5x+3 are the factors of the polynomial,
On factorizing both the factors we get,
(2x+3)(x+1)(x+2+i)(x+2-i)
Hence, the linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

the ratio of doors to windows is 1:5 . There are 186 doors and windows in a building . HOw many doors and windows are there?
Answer:
a. Doors = 31 doors
b. Windows =155 windows
Step-by-step explanation:
Given the following data;
Ratio D:W = 1:5 = 1 + 5 = 6
Total number of doors and windows = 186
Ratio of doors to windows = 1/6
Ratio of windows to doors = 5/6
To find the ratio of the doors;
Doors = 1/6 * 186
Doors = 186/6
Doors =31 doors
To find the ratio of windows;
Windows = 5/6 * 186
Windows = 930/6
Windows =155 windows

expand and simplify {3x+2}{x-1}
Answer:
{3x+2}{x-1} = 3x²-x-2
Step-by-step explanation:
The given expression is :
{3x+2}{x-1}
We can solve it as follows :
{3x+2}{x-1} = 3x(x)+3x(-1) +2(x) +2(-1)
= 3x²-3x+2x-2
= 3x²-x-2
So, the expand form of the given expression is 3x²-x-2.

Answer:
Y-intercept: (0,-0.7)
X-intercept: (-1.2,0)
Explanation:
The Y-intercept is the spot where the line crosses the Y axis (the vertical axis). This always occurs where X=0. For this problem the Y value at this point is -0.7. So, for the coordinates (X,Y) X is 0 and Y is -0.7 so it is (0,-0.7)
The X-intercept is the spot where the line crosses the X axis (the horizontal axis). This always occurs where Y=0. For this problem the X value at this point is -1.2. So, for the coordinates (X,Y) X is -1.2 and Y is 0 so it is (0,-0.7)
