Answer: [tex]2.78m^{2}[/tex]
Step-by-step explanation:
given data:
height of the statue = 80m.
base of the statue = [tex]625m^{2}[/tex].
scale of the statue replica = 1:15.
solution:
[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]
[tex]= \frac{625m^{2} }{225}[/tex]
= [tex]2.78m^{2}[/tex]
the area of the replica is [tex]2.78m^{2}[/tex]
Answer:
2.78 m^2 is the correct answer. :)

Step-by-step explanation:
Given an inequality, what strategies can we use to determine where the boundary line is? Explain your strategies in detail.
4x+3y≥12
Answer:
The strategy is to find the x and y intercept of the given equation
Step-by-step explanation:
4x+3y≥12
In order to determine where the boundary line, we need to first get the x and y-intercept of the inequality expression given;
x-intercept occurs at where y = 0
when y = 0
4x + 3(0)≥12
4x ≥12
x ≥12/4
x≥ 3
Also y intercept occurs at where x = 0
4x+3y≥12
4(0)+ 3y ≥12
3y≥12
y≥12/3
y≥4
Hence the intercept of the line is at (3, 4). A thick line will pass through this point and the upper part of the graph will be shaded. The strategy is to find the x and y intercept of the given equation

A factory makes rectangular sheets of cardboard, each with an area of 2 1 2square feet. Each sheet of cardboard can be cut into smaller pieces of cardboard measuring 1 6square feet. How many smaller pieces of cardboard does each sheet of cardboard provide?
Answer:
2 1/7 pieces
Step-by-step explanation:
A factory makes rectangular sheets of cardboard, each with an area 2 1/2 square feet. Each sheet of cardboard can be cut into smaller pieces of cardboard measuring 1 1/6 square feet. How many smaller pieces of cardboard does each sheet of cardboard provide?
Each sheet of cardboard = 2 1/2 square feet
Each smaller pieces of cardboard = 1 1/6 square feet
Number of smaller pieces of cardboard per sheet of cardboard = Each sheet of cardboard ÷
Each smaller pieces of cardboard
= 2 1/2 square feet ÷ 1 1/6 square feet
= 5/2 ÷ 7/6
= 5/2 × 6/7
= (5*6) / (2*7)
= 30/14
= 15/7
= 2 1/7 pieces
Number of smaller pieces of cardboard per sheet of cardboard = 2 1/7 pieces
The ratio of the number of boys to girls the number of girls in the school 729 and there are 1248 students in the school how many girls are there
Answer:
1005 girls
Step-by-step explanation:
From the question we are given ratio of boys to girls as 7 : 29
Total ratio will be 7 + 29 = 36
Total students in the school = 1248 students
Number of girls in the school = 29/36 * 1248
Number of girls in the school = 29 * 35
Number of girls in the school = 1005
Hence the approximate total number of girls in the school is 1005 girls
Note that the ratio was assumed since we are not given in question

What’s the slope of the line containing the two points
Answer:
The slope is 3/2 or 1.5
Step-by-step explanation:
To find the slope, simply divide the rise by the run. The rise of this line can be found by subtracting one y coordinate by another (it doesn't matter which by which). The run can be found by subtracting one x coordinate by another (it doesn't matter which by which).
So, let's say, for the y coordinates, I choose to subtract 3 by 0. 3 - 0 = 3. 3 is your rise.
For the x coordinates, I can choose to subtract -5 by -7. -5 - (-7) = 2. 2 is your run.
The slope is rise/run, so your answer is 3/2, which, in decimal form, is 1.5.
Hope this helped!
What is the solution to 2/3(9x-6)=4(x+2)+ 2 round to the nearest hundredth
Answer:
7
Step-by-step explanation:
First expand 2/3 (9x-6) = 4 (x+2)+ 2 By doing 2/3 (9x - 6)/3
Which gives you 2/3 (9x - 6)
Then you factor it 2/3 (9x - 6) 6 (3x - 2) get 6 (3x - 2) / 3
then you divide 6/3 with 2
Getting 2 (3x - 2)
The use the distributive law
2 x 3x - 2 x 2
simplify the equation
6x - 4
expand 4 (x +2) + 2: 4x + 10
which then equals 6x-4=4x+10
add 4 to both sides
6x-4+4=4x+10+4
simplify
6x=4x+14
subtract 4x from both sides
simplify again
2x=14
divide both sides by 2
2x/2 = 14/2
simplify one last time and get the answer
x=7

What are the coordinates of point (-2, 4) after a 180 degree rotation?
Answer:
(2,-4)
Step-by-step explanation:
Rotation of a point through 180°, about the origin when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M' (-h, -k).
f(x) = |2x + 1| + 3
g(x) = -2
find (f + g)(x)
A.(f + g)(x) = |2x + 2|
B.(f + g)(x) = |2x| + 2
C.(f + g)(x) = |2x + 1| + 1
D.(f + g)(x) = |2x + 4| - 2
Answer:
(f + g)(x) = I2x + 1I + 1 ⇒ C
Step-by-step explanation:
Let us solve the question
∵ f(x) = I2x + 1I + 3
∵ g(x) = -2
→ We need to find (f + g)(x), which means add the two functions
∵ (f + g)(x) = f(x) + g(x)
→ Substitute the right side of each function on the right side
∴ (f + g)(x) = I2x + 1I + 3 + (-2)
→ Remember (+)(-) = (-)
∴ (f + g)(x) = I2x + 1I + 3 - 2
→ Add the like terms in the right side
∵ (f + g)(x) = I2x + 1I + (3 - 2)
∴ (f + g)(x) = I2x + 1I + 1

F(1) =
2
3
30
Answer:
f(1) = 2
Step-by-step explanation:
To find f(1), substitute x = 1 into f(x), that is
f(1) = 1² + 3(1) - 2 = 1 + 3 - 2 = 2

2x2 - 7x+k=0 is x =-1. Find the value of k.
2
Answer:
this is the correct solution for your question
Answer:
The value of k is -4.
Step-by-step explanation:
In order to find the value of k, you have to substitite x = -1/2 into the equation :
[tex]2 {x}^{2} - 7x + k = 0[/tex]
[tex]let \: x = - \frac{1}{2} [/tex]
[tex]2 {( - \frac{1}{2} )}^{2} - 7( - \frac{1}{2} ) + k = 0[/tex]
[tex]2( \frac{1}{4} ) + \frac{7}{2} + k = 0[/tex]
[tex] \frac{1}{2} + \frac{7}{2} + k = 0[/tex]
[tex]4 + k = 0[/tex]
[tex]k = - 4[/tex]

A 25 -pound bag of dog food costs $20.25 A35 -pound bag of the same dog food costs $27.65 Which bag of dog food is the better buy?
Answer:
The 35 pound bag
Step-by-step explanation:
If you divide the price of the 25 pound bag by the number of pounds it has you get 0.81 dollars per pound
20.25 / 25 = 0.81
However if you divide the price of the 35 pound bag by the number of pounds it has you get 0.79 dollars per pound
27.65 / 35 = 0.79
This means you get more dog food for less in the larger 35 pound bag

Walmart is having a huge 25 % off sale!!!
If the SALE PRICE for a PS4 is $300, what was the ORIGINAL PRICE?
9514 1404 393
Answer:
$400
Step-by-step explanation:
If the price after taking 25% off is $300, then $300 is 75% of the original price.
$300 = 0.75p
$300/0.75 = p = $400
The original price was $400.
_____
Check
0.25 × $400 = $100
$400 -100 = $300 . . . . the price after taking 25% off

The width and length of a rectangular flower bed are in the ratio 5:7. The width is 40 feet. What is the length?
Answer:
56 feet
Step-by-step explanation:
The width and length of a rectangular flower bed are in the ratio 5:7. The width is 40 feet. What is the length?
From the above question, our ratio is given as:
Width : Length
5 : 7
Width = 40 feet ,
To solve for the Length, let us represent the length as x
Width/Length
= 5/7 = 40/x
Cross Multiply
5 × x = 7 × 40
x = 7 × 40/5
x = 56 feet
Hence: The length of the rectangular flower bed = 56 feet

Ericka observed the total variation in the water level over 6.2 years to be −13.64 mm. She compared this to the average annual trend, which shows the water level rising 1.8 mm/year. Remember, she used 6.2 years as her time period. What is the difference between how much average water levels rose and how much the water level fell in the part of the river she observed?
__________millimeters
Answer:
In the area that she observed, the water level fell 13.64mm over 6.4 years, for an average annual rate of change of: -13.64 ÷ 6.2 = -2.2 mm/ year.
