houses cost £100000 one year ago
now they cost £________
this is a 25% increase
Final answer:
The new cost of houses after a 25% increase from the original price of £100,000 is £125,000. You calculate this by finding 25% of £100,000, which is £25,000, and then add it to the original price.
Explanation:
The student is asking how to calculate the new cost of houses after a 25% price increase from the previous year when the houses cost
£100,000. To find the new price, we need to calculate 25% of £100,000 and then add that to the original price.
First, find 25% of £100,000:
0.25
(multiplier for 25%)
× £100,000
(original cost)
= £25,000
(the increase).
Next, add the increase to the original cost:
£100,000
+ £25,000
= £125,000.
Therefore, the new cost of the houses after a 25% increase is £125,000.

1. According to the box and whisker plot below, what was the lower quartile weight of Frank's
classmates?
Weights of Frank's Classmates (in lbs.)
50 75 100 125 150
HHHHHHHHH
a) 65
b) 75
c)
95
d) 125
B
Step-by-step explanation:
I hoped this helped
Based on the provided box and whisker plot, the lower quartile (Q1) represents the 25th percentile of the data, which means 25% of the data points are below this value. To find the lower quartile weight of Frank's classmates, we need to identify the middle value of the lower half of the data.
The box and whisker plot separates the data into four quartiles: the lower whisker, the box (which contains Q1), the median (Q2), and the upper whisker. The box covers the interquartile range (IQR), which contains the middle 50% of the data.
Let's find the lower quartile (Q1) based on the provided data:
Weights of Frank's Classmates (in lbs.): 50, 75, 100, 125, 150
Step 1: Arrange the data in ascending order: 50, 75, 100, 125, 150
Step 2: Find the position of Q1:
Position of Q1 = (25/100) * (Total number of data points + 1)
Position of Q1 = (25/100) * (5 + 1)
Position of Q1 = (25/100) * 6
Position of Q1 = 1.5
Since the position is not a whole number, we need to take the average of the data points at positions 1 and 2.
Step 3: Calculate Q1:
Q1 = (Data at position 1) + [(Position of Q1 - Integer part of Position of Q1) * (Data at position 2 - Data at position 1)]
Q1 = 50 + [(1.5 - 1) * (75 - 50)]
Q1 = 50 + [0.5 * 25]
Q1 = 50 + 12.5
Q1 = 62.5
So, the lower quartile weight of Frank's classmates is 62.5 lbs.

The height of a right circular cylinder is 1.5 times the radius of the base. What is the ratio of the total surface area to the lateral (curved) surface area of the cylinder?
Let r represent the radius of cylinder.
We have been given that the height of a right circular cylinder is 1.5 times the radius of the base. So the height of the cylinder would be [tex]1.5r[/tex].
We will use lateral surface area of pyramid to solve our given problem.
[tex]LSA=2\pi r h[/tex], where,
LSA = Lateral surface area of pyramid,
r = Radius,
h = height.
Upon substituting our given values in above formula, we will get:
[tex]LSA=2\pi r\cdot (1.5)r[/tex]
Now we will find the total surface area of cylinder.
[tex]TSA=2\pi r(r+h)[/tex]
[tex]TSA=2\pi r(r+1.5r)[/tex]
[tex]TSA=2\pi r(2.5r)[/tex]
[tex]\frac{TSA}{LSA}=\frac{2\pi r(2.5r)}{2\pi r(1.5r)}[/tex]
[tex]\frac{TSA}{LSA}=\frac{2.5r}{1.5r}[/tex]
[tex]\frac{TSA}{LSA}=\frac{25}{15}[/tex]
[tex]\frac{TSA}{LSA}=\frac{5}{3}[/tex]
Therefore, the ratio of total surface area to lateral surface area is [tex]5:3[/tex].

f(x)=4x2−16
find the zeros of the function
Answer:
x=2 x=-2
Step-by-step explanation:
f(x)=4x^2−16
f(x)=4(x^2-4)
f(x)=4(x-2)(x+2)
x=2 x=-2
Hope this helps! Please mark brainliest :)
The zeros of the function f(x) = 4x2 − 16 are found by factoring the quadratic equation, which results in two solutions x = -2 and x = 2.
Explanation:To find the zeros of the function f(x) = 4x2 − 16, we need to set the function equal to zero and solve for x:
0 = 4x2 - 16
To solve this quadratic equation, you can factor out the common factor of 4:
0 = 4(x2 - 4)
We now have a difference of squares, which can be factored further:
0 = 4(x + 2)(x - 2)
Set each factor in the parentheses equal to zero:
x + 2 = 0 → x = -2x - 2 = 0 → x = 2So the zeros of the function are x = -2 and x = 2.

Write an exponential model, y=a(b)^x, given the two points (9,171) and (10,190)
Please hurry!
Answer:
[tex]y = 66.25(1.11)^x[/tex]
Step-by-step explanation:
Let's plug in 9 for x and 171 for y into the given exponential equation:
y = [tex]ab^x[/tex]
171 = [tex]ab^9[/tex]
Now do the same with (10, 190):
190 = [tex]ab^{10}[/tex]
Write them both in terms of a and set them equal:
a = 171/[tex]b^9[/tex]
a = 190/[tex]b^{10}[/tex]
171/[tex]b^9[/tex] = 190/[tex]b^{10}[/tex]
Multiply both sides by [tex]b^{10}[/tex]:
171b = 190
b = 190/171 = 10/9 ≈ 1.11
Plug this in to find a:
a = 171 / (10/9)^9 ≈ 66.25
So, the exponential model is:
[tex]y = 66.25(1.11)^x[/tex]
Answer:
y = 66.25[(10/9)^x]
Step-by-step explanation:
171 = a(b⁹)
b⁹ = 171/a
190 = a(b¹⁰)
190 = a(171/a) × b
b = 190/171
b = 10/9
(10/9)⁹ = 171/a
a = 66.24890362

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 17 feet by 17 feet by 2 inches for a patio if the concrete costs $64.00 per cubic yard?
Answer:
$114.17
Step-by-step explanation:
First we need to convert cubic yard to cubic feet.
One yard is equivalent to three feet, so one cubic yard is 3^3 = 27 cubic feet.
So the cost of one cubic feet is 64/27 = $2.3704
We also need to convert from inches to feet.
One inch is 1/12 feet, so 2 inches is 2/12 = 1/6 feet
Now we need to find the volume of the slab:
Volume = 17 * 17 * (1/6) = 48.1667 ft3
Now, to find the cost, we can use a rule of three:
1 cubic feet -> $2.3704
48.1667 cubic feet -> X
X = 48.1667 * 2.3704 = $114.1743

Find the surface area of the sphere. *
We have been given a sphere with radius 8.6 ft. We are asked to find the surface area of the given sphere.
We know that surface area of a sphere is equal to [tex]4\pi r^2[/tex].
[tex]A=4\pi r^2[/tex]
Upon substituting [tex]r=8.6\text{ ft}[/tex] in surface area formula, we will get:
[tex]A=4\pi (8.6\text{ ft})^2[/tex]
[tex]A=4\pi \cdot 73.96\text{ ft}^2[/tex]
[tex]A=295.84\pi\text{ ft}^2[/tex]
[tex]A=929.4087706\text{ ft}^2[/tex]
Upon rounding to nearest hundredth, we will get:
[tex]A\approx 929.41\text{ ft}^2[/tex]
Therefore, the surface of the given sphere would be approximately [tex]929.41\text{ ft}^2[/tex].
