Answer:
9/16 is the scale factor.Step-by-step explanation:
Every transformation has an original figure and a transformed figure.
In order to find the scale factor fo the transformation, we need to divide the transformed dimensions by the original ones.
So, in this case, the poster originally had 3 feet by 2 feet. Then, the reproduced artwork has 2 inches by 1 1/3 inches. Before we divide, we need to transform feet to inches.
We know that 1 feet equals 12 inches, that means
[tex]3ft \frac{12in}{1ft} =36in[/tex]
[tex]2ft\frac{12in}{1ft}=24in[/tex]
Then, we do the divisions
[tex]\frac{36in}{2in}=18\\\frac{24in}{1\frac{1}{3}in }=\frac{24in}{\frac{4}{3}in }=\frac{96}{3}=32[/tex]
Therefore, the scale factor is [tex]\frac{18}{32}=\frac{9}{16}[/tex]

7 plus the sum of a number x and 5 write this phrase as an expression
The equation is: 7 + (x + 5)
The expression for '7 plus the sum of a number x and 5' is written as '7 + (x + 5)'.
The phrase '7 plus the sum of a number x and 5' can be written as an algebraic expression. This involves taking the sum of the variable x and the number 5, and then adding 7 to this sum. In mathematical terms, this is expressed as 7 + (x + 5).
Let's break it down step by step:
First, identify the sum: x + 5.
Next, add 7 to the result of this sum.
So, if we were to evaluate this expression for x = 4, we would calculate it as follows:
7 + (4 + 5) = 7 + 9 = 16
Find -7 -(-3)=
What’s the answer explain !
Because there are 2 minus signs next to each other, we can replace both of them with a single plus sign.
This changes the equation to -7 + 3
Adding to a negative number makes the number appear smaller, so 3 + -7 = -4.
Remove parenthesis
-7=3
Calculate the sum
-4
-15h + 100 = 40, but what is the value of k?
I don't know if you accidentally put down the wrong variable, but the answer for h would be h=4. First things first, you have to subtract 100 from both sides, and this would become -15h=-60. After that, divide -15 on both sides, thus it leaves you with h by itself and it's value is 4. h=4

Paco, Jayden, Brett each made a stack of superheroes cards. Pacos stack was 0.342 meter high. Jaydens stack was 0.41 meter high. Brett stack was 0.405 meter high. Write a number sentence that compares Jayden stack of cards Brett stack of cards.
Jayden's stack of superhero cards, which is 0.41 meters high, is taller than Brett's stack of superhero cards, which is 0.405 meters high. The number sentence to compare them is 0.41 > 0.405.
The student is asking to write a number sentence that compares Jayden's stack of cards to Brett's stack of cards.
Jayden's stack was 0.41 meter high, and Brett's stack was 0.405 meter high. To compare these two stacks, we look at the decimal values given for the heights. Since 0.41 is greater than 0.405, the number sentence that compares the two stacks is:
Jayden's stack > Brett's stack
Or in terms of the specific values:
0.41 > 0.405
This shows that Jayden's stack of cards is taller than Brett's stack of cards.

Maya is on the swim team. Each day she swims 750 m. Use the facts to find how much this is in kilometers
Maya swims 0.75 kilometers each day because to convert 750 meters to kilometers, we divide by 1,000.
The student wishes to know how many kilometers Maya swims each day if she swims 750 meters. To convert meters to kilometers, we use the fact that 1 kilometer is equivalent to 1,000 meters. So, to find out how many kilometers 750 meters is, we divide the number of meters by 1,000.
750 meters \/ 1,000 = 0.75 kilometers
Therefore, Maya swims 0.75 kilometers each day.

What substitution should be used to rewrite 4x^4-21x^2+20=0 as a quadratic equation
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
Answer:
4y^2 - 21y + 20 = 0
Step-by-step explanation:
As (4x^4 - 21x^2 + 20=0) being a biquadratic equation, meaning it is a 4-degree equation without the terms of degree 1 and 3.
To solve this particular case you only need to replace the variables of degree 4 and 2 for a new variable of degree 2 and 1 and solve it as regular quadratic equation and then undo the change.
* Using a new variable we can rewrite the equation:
Let y be the new variable;
y= x^2, then y^2= x^4
Then we have;
4y^2- 21y+20=0
Solve for y and then find X which will be the roots for the biquadratic equation.

A car travels 150km on 12 L of gasonline. How many liters are there of gasoline needed to travel 500km
You can use the given distance to amount of gasoline used relationship to find how much gasoline is needed for 1 km of traveling. Then use that data to find the amount of gasoline needed to travel 500 km.
The amount of gasoline needed to travel 500 km is 40 L
How to find the gasoline used for 1 km of distance traveled?We can equate the 150 km figure to 12 L use of gasoline on the basis of usage.
Thus,
[tex]\rm 150 \: km = 12 \: L\\\\\\\text{Dividing both quantities in 150 parts}\\\\\\dfrac{150}{150} \: km = \dfrac{12}{150} \: L\\\\1 \: km = 0.08 \: L[/tex]
Thus, there will be use of 0.08 L gasoline for travelling 1 km by that same car.
Using that above derived relationship, we can find the amount of gasoline needed to travel 500 km by that same car.
[tex]1 \rm \: km = 0.08 \: L\\\\\text{Multiplying 500 on both the sides}\\\\500 \: km = 40 \: L[/tex]
Thus,
The amount of gasoline needed to travel 500 km is 40 L
