Answer:

the sum of B and C is negative

A + D = B

The quotient of C and B is equivelent to -2/3

Step-by-step explanation:

The quotient of C and B is equivalent to -2/3. Therefore, the correct option is option D among all the given options.

A picture of numbers along a straight line is called a number line. It serves as a guide for contrasting and arranging numbers. Any real number, including all whole numbers and natural numbers, can be represented by it. Just to refresh your memory, a whole number is a collection of numbers that contains all counting numbers.

Comparing numbers is made simpler by writing them on a number line. As seen in the aforementioned graphic, the integers to the left are smaller compared to the integers for the right. As an illustration, the numbers 0 and 1 are less than each other, as are the numbers -1 and -2. The sum of B and C is negative.

Therefore, the correct option is option D.

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

Your answer would be 900m².

We can find this by finding the area of each of the shapes that make up the surface of this prism.

First there is the bottom of the prism, which would be 11 × 24 = 264m².

Then you have the two triangles on the sides of the prism, which are both (10 × 24)/2 each, which equals 120m² for each triangle. This means that the area for both triangles is 120 × 2 = 240m².

Next we have the area of the back of the prism, which is 11 × 10 = 110m².

Finally we need to find the area of the rectangle on top of the prism, which is 11 × 26 = 286m²

This means your final answer would be the sum of all of these, which is 264 + 240 + 110 + 286 = 900m².

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.

We have been an artist is creating a sculpture where a globe with a diameter of 48 inches sits in a cone like a scoop of ice cream. She wants the cone of her sculpture to be geometrically similar to an actual ice cream cone that has a diameter of 2 1/2 inches and a height of 6 inches.

We will use proportions to solve our given problem.

[tex]2\frac{1}{2}=2.5[/tex]

[tex]\frac{\text{Height of sculpture}}{\text{Diameter of sculpture}}=\frac{\text{Height of cone}}{\text{Diameter of cone}}[/tex]

[tex]\frac{\text{Height of sculpture}}{48}=\frac{6}{2.5}[/tex]

[tex]\frac{\text{Height of sculpture}}{48}\cdot 48=\frac{6}{2.5}\cdot 48[/tex]

[tex]\text{Height of sculpture}=6\cdot 19.2[/tex]

[tex]\text{Height of sculpture}=115.2[/tex]

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].

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].

Answer: 24 days

Step-by-step explanation:

Sandy plays tennis once every 6 six days while Jim plays tennis once every 8 eight days.

To get the number of days they will play on the same day again, we find the lowest common multiple for the numbers.

The lowest common multiple is the smallest positive integer which is evenly divisible by both 6 and 8.

6 = 6, 12, 24, 30

8 = 8, 16, 24, 32

The lowest common multiple is 24.

In 24 days, they will play on the same day again

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

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.

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.

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:

So the zeros of the function are x = -2 and x = 2.
