a maple tree shades an area of 7 1/2 m square. in the scale drawing, the maple tree shades an area of 12 1/2 cm square. in the scale drawing how many square centimeters represents 1 m squared
Answers
The number of centimeter squares in the scale drawing for each 1 m squared is 1.67.
What is Scale factor?The scale factor is a type of measurement which is used to increase or decrease the size of an object keeping its shape as the same. It can be determined by taking the ratio of the new and the original dimension of the object.
Given that,
The area shaded by a maple tree is 7(¹/₂) m².
And, the area shaded in scale drawing is 12(¹/₂) cm².
The required number of square centimeters can be found by dividing the two areas as follows,
12(¹/₂) / 7(¹/₂)
= (25/2)/(15/2)
= 25 / 15
= 5 / 3
= 1.67
Hence, the number of centimeter squares in the scale area is 1.67.

The equation that represents the total amount will be y = 25x + 50.
What is a linear equation?A connection between two or more factors results in a linear model when displayed on a graph. The parameter will have a degree of one.
The linear equation is given as,
y = mx + c
Where c is the line's y-intercept and m is the line's y-slope.
A photo studio charges a $50 sitting fee and $25 per photo sheet purchased.
Let x be the number of photo sheets purchased and y be the total amount.
The slope of the equation is 25 and the y-intercept will be 50.
y = 25x + 50
The equation that represents the total amount will be y = 25x + 50.

MLN=QPR. What is the measure of <1 and <2?
Answers
Answer:
B. <1 = 90, <2 = 40
Step-by-step explanation:
Given that ∆MLN = ∆QPR, it follows that the measure of their corresponding angles would be of the same measure.
<P = right angle = 90°
<1 corresponds to <P, therefore, <1 = 90°
<R = 40°
<2 corresponds to <R, therefore, <2 = 40°.
The answer would be: B. <1 = 90, <2 = 40

How do you write a unit rate?An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate. Examples of popular unit rates are the speed in miles per hour, the amount of energy used in miles per gallon, and the speed of the internet in megabits per second. Miles per hour, blinks per second, calories per serving, steps per day, and heartbeats per minute are a few instances of unit rates.7.5 mL/ hr
The unit rate for the situation is mL per hour

To work out this you need to do the change in y/ the change in x.
So we take 2 points you are given in the table- e.g (1,5) and (2,1)
So the change in y is from 5 to 1 so it is -4 and the change in x is from 1 to 2 so is 1.
Then you have -4/1 which is just -4.

have a great day :)
Because multiplication is the converse of division,
If x/y=z then x=?x/y=z
x=yz
Division and multiplication are inverse operations. This means they "undo" each other. You can check your answer by multiplying the quotient by the divisor. You should get the dividend.
Just like addition is the converse of subtraction.
If x/y=z,
then x=yz.
If x divided by y is equal to z, then x equals y times z. These are the rules of arithmetic. If they weren't true the universe would fall apart! The rule can be used as a check that you have the right answer.
Therefore converse of division is the answer.

4(x-1)=-8 how do i answer this
Answers
Answer: x= -1
Step-by-step explanation:
4(x-1)=-8
First distribute
4x-4=-8
Now add 4 to -8
4x=-4
Now divide by 4
X=-1
The answer is x = -1
Step-by-step explanation: When it comes to solving for a variable (x) you have to distribute if there is parenthesis and then use inverse operations to get the answer.
4(x-1)=-8 Distribute
4x - 4 = -8 Subtract 4 from both sides
4x = -4 Divide 4 on both sides
x = - 1 and that is your answer
