Answer:
No, a 24 square centimeter rectangle is smaller than a 24 square inch rectangle
Step-by-step explanation:
we know that
[tex]1\ in=2.54\ cm[/tex]
so
Convert in^2 to cm^2
[tex]24\ in^2=24(2.54)^2=154.8\ cm^2[/tex]
so
[tex]24\ cm^2 < 154.8\ cm^2[/tex]
therefore
[tex]24\ cm^2 < 24\ in^2[/tex]
A 24 square inch rectangle is larger than a 24 square centimeter rectangle due to unit conversion.
No, a 24 square inch rectangle is larger than a 24 square centimeter rectangle.
To compare rectangles of different units, we need to convert the units to the same measurement. Since 1 inch is equal to 2.54 centimeters, a square inch is larger than a square centimeter.
Therefore, a 24 square inch rectangle has a greater area than a 24 square centimeter rectangle.
Suppose Ellie starts making a lamb stew using a 6.5-quart pot. She decides to make a bigger stew. She pours everything into a pot that is 40 percent bigger. How big is the bigger pot?
Answer:
The bigger pot is a 9.1-quart pot
Step-by-step explanation:
Initial pot size = 6.5-quart
New pot is 40% bigger than the initial pot size
Bigger pot size = 6.5-quart + (0.4 × 6.5-quart) = 6.5-quart + 2.6-quart = 9.1-quart
A frame around a rectangular family portrait has a perimeter of 150 inches. The length is ten more than four times the width. Find the length and width of the frame.
Answer: The length is 62 inches and the width is 13 inches
Step-by-step explanation: The perimeter of the rectangular portrait has been given as 150 inches. We also know that the perimeter of a rectangle is given as
Perimeter= 2(L + W)
However we don't have the measurements for the length and width. What we do have are descriptions of both. The length is given as W, while the length is ten more than four times the width. That is, the length equals
10 + 4W
Therefore we have the length and the width as
L = 4W + 10 and
W = W
If the perimeter is 150, and
Perimeter = 2(L + W) then,
150 = 2(4W + 10 + W)
150 = 2(5W + 10)
150 = 10W + 20
Subtract 20 from both sides of the equation
130 = 10W
Divide both sides of the equation by 10
13 = W
With that in mind we can now calculate the length as
L = 4W + 10
Substitute for the value of W
L = 4(13) + 10
L = 52 + 10
L = 62
Therefore, the length is 62 inches and the width is 13 inches
Answer:
Length = 62 inches, Width = 13 inches
Step-by-step explanation:
Let L represent the length of the frame, W, the width and P, the perimeter
Perimeter of a rectangle, P = 2 (L + W) .....eq 1
Also, P = 150 inches
and
L = 10 + 4W .....eq 2
Slotting in the respective values of P and L in eq 1
150 = 2 {(10 + 4W) + W}
Expanding the bracket
150 + 2 (10 + 5W)
150 = 20 + 10W
Subtracting 20 from both sides of the equation
150 - 20 = 20 - 20 + 10W
130 = 10W
Dividing both sides by the coefficient of W which is 10
13 = W
Therefore, W = 13 inches
Slotting in the value of W in eq 2
L = 10 + 4 (13)
L = 10 + 52
L = 62 inches
Lets ensure that the values of L and W are correct
P = 2 (L + W)
150 = 2 (13 + 62)
150 = 2(75)
150 = 150
Hence, L = 62 inches, W = 13 inches
The expression 210,000\left(1.02\right)^x210,000(1.02)
x
models the estimated home value after x years. Which statement is the correct representation of the 1.02 in the expression?
The house has a starting value of 1.02.
The house is decreasing in value by 2% each year.
The house is increasing in value by 2% each year.
The value of the house is changing by 0.02% each year.
Answer:
The house is increasing in value by 2% each year.
Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:
[tex] \frac{1.02-1}{1} *100 = 2\%[/tex]
Step-by-step explanation:
For this case if we have this expression
[tex] 210000(1.02)^x[/tex]
We have the same functional forma like the exponential model given by:
[tex] y = a b^x[/tex]
Where a = 210000 represent the constant or initial value and b = 1.02 represent the base.
So let's analyze the possible options:
The house has a starting value of 1.02.
False the starting value for this case is 210000 since if x=0 then we see that the value is 210000
The house is decreasing in value by 2% each year.
False the increase is 1.02 each year so then in % we have
[tex] \frac{1.02-1}{1} *100 = 2\%[/tex]
We have an increase of 2% each year
The house is increasing in value by 2% each year.
Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:
[tex] \frac{1.02-1}{1} *100 = 2\%[/tex]
The value of the house is changing by 0.02% each year.
False the increase is 2% per year

17. WEATHER Heavy rain in Brieanne's town caused the river to rise. The river rose three
inches the first day, and each day after rose twice as much as the previous day. How
much did the river rise in five days?
Answer:
30
Step-by-step explanation:
It states that it rained twice as much in 5 days all you do is multiply the 2 times 3 which is 6 so then u multiply 6 times 5 which is 30.
The river rose a total of 93 inches over five days.
The question asks how much a river rises in five days given a certain pattern of increase. To find the solution, we use a geometric sequence because the river rises by a constant multiple each day. On the first day, the river rises three inches. Since on each subsequent day the river rises by twice the amount it did the previous day, the sequence of increases over five days is: 3 inches, 6 inches, 12 inches, 24 inches, and 48 inches.
The total rise of the river is the sum of these increases:
3 + 6 + 12 + 24 + 48 = 93 inches.
Therefore, the river rose a total of 93 inches over the span of five days.

Step-by-step explanation:
x + 6y = -7
2x + 12y = -14
ALL OF THESE WILL BE SOLVE FOR X AND Y!!!
Problem 1 Solve For x: x=−6y−7
Show work: Add -6y to both sides.
x+6y+−6y=−7+−6y
x=−6y−7
Problem 1 Solve For y: y = -1/6x + -7/6
Show work: Add -x to both sides.
x+6y+−x=−7+−x
6y=−x−7
Step 2: Divide both sides by 6.
6y/6 = -x -7/6
Problem 2 Solve For x: x=−6y−7
Show work: Add -12y to both sides.
2x+12y+−12y=−14+−12y
2x=−12y−14
Step 2: Divide both sides by 2.
2x/2 = -12y - 14/2
Problem 2 Sovle For y: y=-1/6x + -7/6
Show work: Add -2x to both sides.
2x+12y+−2x=−14+−2x
12y=−2x−14
Step 2: Divide both sides by 12.
12y/12 = -2x-14/12

Answer:
Please, find the image with the diagram of the lines corresponding to this question:
The answers are:
Equation: m ∠ DCE = 180º - x
Value of x = 60º
Explanation:
First question:
You must use the fact that the angles DCE and BCD are adjacent angles, because they share the vertex (C) and have a common side (CD).
Thus, as a first fact, the measure of the angle BCE is equal to the sum of the measures of the angles BCD and DCE.
On the other hand, BE is a straight line, thus the measure of angle BCE is 180º.
Hence, you can write:
m ∠ DCE + m ∠ DCB = 180ºm ∠ DCE + x = 180ºm ∠ DCE = 180º - xSecond question:
Solve for x:
Given: m ∠ DCE = 180º - xAdd x to both sides: m ∠ DCE + x = 180º Subtract m ∠ DCE from both sides: x = 180º - m ∠DCESubstitute m ∠DCE with 120º:
x = 180º - 120º = 60ºHence, for m ∠DCE = 120º, x = 60º.

Final answer:
The correct factors of the polynomial +5x+3 are (2x+3)(x+1), as they multiply to give the original polynomial. None of the other provided options yield the correct polynomial upon multiplication.
Explanation:
The question asks to identify the factors of the polynomial +5x+3. Factors are expressions that, when evaluated, produce the value of the polynomial. Let's examine the provided options to find which pair of binomials gives us the correct polynomial upon multiplication:
(2x+3)(x+1) = 2x² + 2x + 3x + 3 = 2x² + 5x + 3, which matches the original polynomial.
(2x-3)(x-1) = 2x² - 2x - 3x + 3 = 2x² - 5x + 3, which does not match the original polynomial.
(3x+2)(x+1) = 3x² + 3x + 2x + 2 = 3x² + 5x + 2, which does not match the original polynomial.
(3x-2)(x-1) = 3x² - 3x - 2x + 2 = 3x² - 5x + 2, which does not match the original polynomial.
Therefore, the correct factors of the polynomial +5x+3 are (2x+3)(x+1).

you can easily simplify a large improper fraction by finding a common number.
in this case the number is 6.
6x5=30 & 6x3=18
therefore, if you divide each number by 6 you get 5/3
decimal: 1.66667 or 1.67 or 1.7
improper fraction: 5/3
proper fraction 1 2/3
Final answer:
30 divided by 18 as an improper fraction is ⅓, or 5/3, obtained by converting the division result into a mixed number and then back into an improper fraction.
Explanation:
To convert 30 divided by 18 into an improper fraction, you first divide 30 by 18 to get the decimal form, which is approximately 1.666. To express this as an improper fraction, we recognize that 1.666 is 1 and 2/3 in mixed number form.
Since 2/3 is already a fraction, we can convert the mixed number back into an improper fraction by multiplying the whole number 1 by the denominator 3 and then adding the numerator 2. This gives us 3 + 2 = 5, so the improper fraction is 5/3.
