The actual dimensions of Sarah's classroom are 20 feet by 30 feet, based on a scale of 1 inch representing 10 feet on the floor plan.
If 1 inch on the floor plan represents 10 feet in reality, we can determine the actual dimensions of Sarah's classroom by multiplying the dimensions on the floor plan by 10.
The width of Sarah's classroom on the floor plan is 2 inches, so the actual width would be 2 inches * 10 feet/inch = 20 feet. Similarly, the length of Sarah's classroom on the floor plan is 3 inches, so the actual length would be 3 inches * 10 feet/inch = 30 feet.
Therefore, the actual dimensions of Sarah's classroom are 20 feet by 30 feet. This means that the classroom occupies a rectangular space with a width of 20 feet and a length of 30 feet. It is important to note that these measurements are scaled up from the floor plan according to the given ratio of 1 inch to 10 feet.

We want to factor the following expression:
81x^6– (y+1)^2
We can factor the expression as (U +V)(U-V) where U and V are either constant integers or single-
variable expressions.
1) What are U and V?
Answer:
We have [tex]\mathbf{U= 9x^3 \:and\:V=y+1}[/tex]
Step-by-step explanation:
We want to factor the expression [tex]81x^6-(y+1)^2[/tex] in the form of (U+V)(U-V)
We need to find U and V
We can use formula : [tex]a^2-b^2=(a+b)(a-b)[/tex]
We can write [tex]81x^6[/tex] as [tex](9x^3)^2[/tex]
Now we have the expression:
[tex]81x^6-(y+1)^2\\=(9x^3)^2-(y+1)^2[/tex]
Applying formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]
[tex]=(9x^3+y+1)(9x^3-(y+1))\\=(9x^3+y+1)(9x^3-y-1)[/tex]
So, we have [tex]\mathbf{U= 9x^3 \:and\:V=y+1}[/tex]

Piper invested $4.700 in an account paying an interest rate of 4.8% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 19 years?
Answer:
The answer to the nearest CENT is A= 11699.69
The amount of money would be $11.4 in the account after 19 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A = P(1+r/100)ⁿ
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
Given that Piper invested $4.700 in an account paying an interest rate of 4.8% compounded continuously.
p = $4.700
r =4.8%
t = 19 years
A = P(1+r/100)ⁿ
Substitute the values of p,r, and t in the formula,
A = 4.700 (1 + 4.8/100)¹⁹
A = 4.700 (1 + 0.048)¹⁹
A = 4.700 (1.048)¹⁹
A = 11.454133
Rounded to the nearest cent
A = 11.4
Therefore, the amount of money would be $11.4 in the account after 19 years.

The lengths of the hypotenuse and one leg of a right

of the angle opposite the leg whose length is known.
A. 20.63° B. 69.37° C. 19.41° D. 9.83°E. 46.90°
The measure of the angle is 20.63 degrees if the lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively option (A) is correct.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
It is given that:
The lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively.
As we know,
Applying sin ratio
sinA = perpendicular/hypotenuse
sinA = 3.7/10.5
sinA = 0.35
sinA = 20.63 degrees
Thus, the measure of the angle is 20.63 degrees if the lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively option (A) is correct.

ASAP BRAINLIEST !! Luis is given the fraction 4/5. He is told to create an equivalent fraction with a numerator of 32. Explain the steps you’d use to solve for the missing denominator. Answer in 2-3 sentences.
Answer: answer 40.
Step-by-step explanation:
Note : lets make x the missing denominator.
I would take the 4/5 and set it equals to 32/x
we then cross multiply
where it would be 4 * x = 32 * 5
it would then be 4x = 160
we would then divide 160 by 4
x = 160/ 4
and x would be 40
.... therefore the missing denominator is 40.
Answer:
Your fraction would be 32/40
Step-by-step explanation:
For it to be equivalent it has to be equal to 4/5. what i did was divided 32 by for and got 8. I then multiplied 4/5 and 8/8 and the answer was 32/40. I multiplied by 8/8 because for it to be equivalent i have to do the same thing to both the numerator and denominator.

Solve each inequality:
||x+4|-7|<5
The value of the inequality is x < 8.
How to calculate the inequality?It should be noted that from the information, we are to.eolve the inequality |x+4|-7 <5.
This will be:
|x+4|-7 <5
x +4 <5 + 7
x + 4 < 12
Subtract 4 from both sides
x + 4 - 4 < 12 - 4
x < 8
Therefore, the value of the inequality is x < 8.

YOUT Tasha earned $50 from babysitting for 4 hours. What is her hourly rate?
Solve for x plz.aaaa
Okay!
All we need to do to solve for x is to set up an equation!
the equation 3x + 4 represent the number of degrees of the bottom angle
→To set up the equation, however, we must find what the bottom angle is!
→This is easy since we know that all triangle are 180°
→The diagram already gives us to angles, so to find the third angle, we use simple subtraction
*the little corner with the red square is always 90°
180 = 90 + 50 + ?
? = 180 - 90 - 50
? = 40°
The angle is 40° !
→Now we can finally find x!
→To find x, we just set the equation they give us equal the degrees of the angle that we just found
3x + 4 = 40°

Students were required to go to the parking lot and select random cars or trucks, with replacement. The purpose was to gather the license plate from exactly 2 Toyota trucks. (For simplicity purposes, let's assume that there were only cars or trucks. In addition, the make of all cars and trucks were either Toyota and Honda.) The students had a further restriction of NOT being allowed to examine more than 3 automobiles to get the required data. What is the likelihood that a student would be successful in finding two Toyota trucks? The following probabilities represent the makes and models in the parking lot on that day: P(Car) = 0.743, P(Toyota | Car) = 0.431, and P(Honda | Truck) = 0.693.

Two figures are shown below.
Which of the following statements correctly explains whether or not the two figures are congruent?
The two figures are congruent since there is a reflection that carries one figure onto the other.
O The two figures are congruent since there is a rotation that carries one figure onto the other.
O The two figures are not congruent since the two figures are oriented differently.
O The two figures are not congruent since there is no translation that carries one figure onto the other.
Answer: B
Step-by-step explanation:
The 2 figures given would be congruent since there seems to be a reflection that carries 1 figure onto the another one. A further explanation is below.
If somehow the matching sides of two components or figures have been of similar length and form, they are said to be congruent. They constitute congruent when one image or graphic entirely encompasses some other figure (both with and without rotations skills).Whenever we turn or twist the above diagram clockwise by something like 90° ∠, it becomes exactly like the ones below.
Thus the answer above i.e., "Option 1" is appropriate.

George had 27 arcade tokens. He used t tokens to play video games. Then, he used 14 tokens for a stuffed animal. Now, he has 5 tokens left. How many tokens did George use to play video games?
Answer:
George used 8 tokens to play video games.
Step-by-step explanation:
First, let's subtract 5 from 27.
27 - 5 = 22
So, George spent a total of 22 arcade tokens.
Now, let's subtract 14 from 22 to find the value of t.
22 - 14 = 8.
Therefore, George used 8 tokens to play video games.
