The lowest possible value of the house is £205000 and highest possible value is £214999.99...
Given that:
The house is valued £210000, correct to 2 significant figures.
Since its correct to 2 significant figures, thus there is error of approx 10000 range in £210000
The lowest possible number that would round up to 2 significant numbers to £210000 is £205000 since any value lower than that would look like £204..... which won't round up to £21..... but £20....
Similarly, the highest possible number that would round up to 2 significant figures to £210000 is £214999.999... since any real number bigger than that would make starting digit of the number as £215.... and thus 2 significant figure rounding will lead to £22....
Thus, the lowest possible value of the house is £205000 and highest possible value is £214999.99...

A: 14
B: 16
C: 13.5
D: 14
Answer Is Option(b.) :-To find the greatest area among the given rectangles, calculate the area of each rectangle by multiplying the base by height. The greatest area is of rectangle b.
Explanation:The subject matter of this question involves finding the area of rectangles. In mathematics, the area of a rectangle is calculated by multiplying its base (b) by its height (h), represented as A = b x h. In this question, you are given four different rectangles (a, b, c, and d) with varying base and height values. You need to calculate the area for each and determine which one is the greatest:
For rectangle a, the area is b x h = 4 x 3.5 = 14 For rectangle b, the area is b x h = 0.8 x 20 = 16 For rectangle c, the area is b x h = 6 x 2.25 = 13.5 For rectangle d, the area is b x h = 10 x 1.4 = 14
After calculations, you can see that rectangle b has the greatest area.

During a heavy rainstorm, a city in Florida received
12 1/4 inches of rain in 25 1/2 hours. What is the approximate
rainfall rate in inches per hour?
A about 2 inches per hour
B about 1/4 inch per hour
C about 1 inch per hour
D about 1/2 inch per hour
Answer: D. About [tex]\frac{1}{2}[/tex] inches per hour.
Step-by-step explanation:
1. The city received [tex]12^{\frac{1}{4}}[/tex] inches of rain in [tex]25^{\frac{1}{2}}[/tex] hours.
2. Let's write the mixed number as decimal numbers:
[tex]12^{\frac{1}{4}}in=12.25in[/tex]
[tex]25^{\frac{1}{2}}h=25.5h[/tex]
3. To find the approximate rainfall rate in inches per hour, you must divide 12.25 inches by 25.5 hours, as following:
[tex]\frac{12.25in}{25.5h}=0.48\frac{in}{h}[/tex]
4. If you round the result to the nearest tenth, you obtain:
[tex]0.5\frac{in}{h}=\frac{1}{2}\frac{in}{h}[/tex]
5. Therefore, the answer is the option D.
The approximate rainfall rate is closest to 0.5 inches per hour therefore the correct answer is Option D.
To determine the approximate rainfall rate in inches per hour, we need to divide the total amount of rainfall by the duration over which it fell.
Total rainfall: [tex]12 \frac{1}{4}[/tex] inches (which is equal to 12.25 inches)Duration: 25 [tex]\frac{1}{2}[/tex] hours (which is equal to 25.5 hours)Using the formula for intensity:
Intensity (inches per hour) = Depth (inches) / Duration (hours)Intensity = 12.25 inches / 25.5 hours ≈ 0.48 inches per hourThe approximate rainfall rate is closest to 0.5 inches per hour, so the correct answer is Option D: about 1/2 inch per hour.

Sarah owns a car that runs on a mixture of gasoline and ethanol. She can buy fuels that have 85% ethanol or 25% ethanol. How much of each type of fuel should she buy if she wants to fill her 20 gallon tank with a mixture of fuel that contains 50% ethanol?
Denise needs to buy 25/3 gallons of 85% ethanol and 35/3 gallons of 25% ethanol to have 20 gallons of 50% ethanol.
x | y | 20 gal
use x and y because you don't know how much she needs.
0.85x | 0.25y | 20(0.5)
85% is 85/100 or 0.85, and you need that much of x, same goes for the 25% and 50% mixtures
so now you can make up 2 equations
1) x + y = 20
2) 0.85x + 0.25y= 10 (you get 10 when you multiply 20 by 0.5)
now you can solve for x or y using substitution. first rewrite 1) in terms of x or y:
x+ y= 20 ----> y= 20 - x
now you can substitute 20- x for y in the second equation..
0.85x + 0.25y= 10
0.85x + 0.25(20-x)= 10 distribute here..(0.25 * 20 and 0.25 * (-x) )
0.85x + 5 - 0.25x = 10 combine like terms
0.6x +5 = 10 move the 5 over to the other side
0.6x= 10 -5
0.6x = 5 divide both sides by 0.6
x= 25/3 or 8.3 now you know the amount of x so you can substitue this back into the first equation to find y.
0.85x + 0.25y= 10
0.85(25/3) +0.25y= 10
85/12 + 0.25y= 10
0.25y = 10- 85/12
0.25y= 35/12
y= 35/3 or 11.6
you can check by putting these values into the euations:
1) x+ y= 20
25/3 + 35/3 =20
20= 20 good so far
2) 0.85x + 0.25y= 10
0.85(25/3) + 0.25(35/3)=10
10 = 10 so our values for x and y work
What is the value of y 10 18 2y+4 10+2x
Answer:
[tex]y=3[/tex]
Step-by-step explanation:
Given figure is a rectangle.
In a rectangle , opposite sides are equal
to find out y we equate the opposite sides 10 and 2y+4
[tex]10=2y+4[/tex]
Subtract 4 from both sides
[tex]10-4=2y+4-4[/tex]
[tex]6= 2y[/tex]
Divide both sides by 2
[tex]y=3[/tex]
explain in words how to find the product of -4(-1.5) on the number line
Multiplying Negatives odd # of negatives means negative answer. even means positive answer.
-4(1.5) Change both to improper fractions
-4/1(6/5) Multiply
-24/5 Simplify
-4 4/5 THE END
To find the product of -4(-1.5) on the number line, start from zero, move 4 units to the left due to the negative sign, and then move 6 units (4 x 1.5) to the right because of the negative multiplied by a negative rule. The result is 6.
Explanation:To find the product of -4(-1.5) on the number line, you would follow a few steps. First, choose your starting point on the number line. In this case, the starting point would be zero.
Next, because the first number is negative, move 4 units to the left from zero. Since the second number is also negative, it changes the direction. So multiply by 1.5 in the opposite direction, which means moving to the right on the number line.
However, as it's a decimal multiplication you need to move 1.5 times or multiply the distance you moved when you moved 1 unit 4 times. It's like taking 1.5 steps to the right for each of the 4 steps we initially moved to the left. In the end, you will end up 6 units to the right of 0. Thus, the product of -4 and -1.5 is 6.

Write 337,060 in expanded form using exponents
1. expand using place value.
337,060 = 300,000 + 30,000 + 7,000 + 000 + 60 + 0
Next, we will use exponents:
300,000 = 3 * 10^5
30,000 = 3 * 10^4
7,000 = 7 * 10^3
000 = 0 * 10^2
60 = 6 * 10
0 = 0 * 10^0
then after combing these exponents, we can write the number as:
337,060 = 3 * 10^5 + 3 * 10^4 + 7 * 10^3 + 0 * 10^2 + 6 * 10 + 0 * 10^0
Finally, removing the meaningless zeroes, we would end up with:
337,060 = 3 * 10^5 + 3 * 10^4 + 7 * 10^3 + 6 * 10
What is the equation of the verticl line through (5,2)?
Final answer:
The equation of a vertical line passing through the point (5,2) is x = 5. This type of line has an undefined slope and is defined by its x-coordinate, not dependent on the y-coordinate.
Explanation:
The equation of a vertical line that passes through the point (5,2) can be determined by understanding that a vertical line has an undefined slope and does not depend on the y-coordinate for its location on a coordinate plane. Instead, a vertical line's location is solely determined by its x-coordinate. Therefore, the equation of a vertical line that passes through (5,2) will have the same x-coordinate for all its points. This means that the equation for the vertical line through (5,2) is simply x = 5.
This equation is different from the conventional y = mx + b, which defines a straight line with a slope m and y-intercept b. In the case of a vertical line, the slope is undefined, and therefore, the standard linear equation cannot be applied. Instead, the equation is independent of y and is expressed only in terms of the constant x-value of the vertical line.

Analyze the following pattern: 1, 2, 5, 10, 17, what is the 8th term of the pattern
To find the 8th term of the pattern 1, 2, 5, 10, 17, analyze the differences between consecutive terms and find the common difference. Add that common difference to the 7th term to find the 8th term.
Explanation:To analyze the pattern, we can observe that the difference between consecutive terms is increasing by 1 each time. Let's find the common difference:
2 - 1 = 15 - 2 = 310 - 5 = 517 - 10 = 7From these differences, we can see that the common difference is increasing by 2 each time. So the difference between the 7th term and the 6th term would be 7 + 2 = 9. Using this pattern, we can find the 8th term:
17 + 9 = 264x-10+14+7x-10x+2
