Answer:

AC=16.2 units

Step-by-step explanation:

we know that

The triangle ABC is an isosceles triangle

so

AX=XC

because triangles ABX and CBX are congruents

AC=2*AX

see the attached figure to better understand the problem

therefore

AC=2*8.1=16.2 units

Final answer:

To find the length of AC, we add the lengths of segments AX and BC, giving us AC = 8.1 + 18.5, which equals 26.6 units.

Explanation:

If we are given that AB = 18.5 units, AX = 8.1 units, and BC = 18.5 units, then to find the length of AC, we simply need to add the lengths of segments AX and BC together, since AX and BC are adjacent segments on line AC. The formula to calculate AC in this situation is:

AC = AX + BC

Substituting the given values into this formula gives us:

AC = 8.1 units + 18.5 units = 26.6 units

Therefore, the length of segment AC is 26.6 units.

Answer:

Given graph represents function.

Step-by-step explanation:

We have been given a graph. Now we need to find if the given graph represents function or not.

To check if any graph represents function or not, we apply vertical line test. That means if there exists any vertical line that crosses the given graph more than once then the given graph is not a function.

Now if you draw vertical lines then you won't find any such vertical line which crosses graph more than once.

Hence given graph represents function.

Answer:

[tex]f(x=\sqrt{x}-2[/tex].

Step-by-step explanation:

We have been given graph of a function. We are supposed to find the function formula.

Upon looking at our given function, we can see that it is transformed form of a square root function.

We know that square root parent function is in form [tex]f(x)=\sqrt{x}[/tex].

We can see that our given graph is shifted down along y-axis. The rule for shifting a graph down along y-axis is: [tex]f(x)\rightarrow f(x)-a[/tex], where graph of [tex]f(x)[/tex] is shifted down by a units.

So our function will be in form [tex]f(x=\sqrt{x}-a[/tex].

From our attached file, we can see that value of 'a' is 2.

Therefore, our required function would be [tex]f(x=\sqrt{x}-2[/tex].

Step-by-step explanation: 28-13

What your are going to want to do is look for the average of the number (hope this helps some what!) good luck

The median is 133.5, the first quartile is 128, the third quartile is 139, and the interquartile range is 11.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

To find the median, first we need to order the data set from least to greatest:

106, 127, 129, 132, 135, 138, 140, 158

There are 8 data points, so the median is the average of the 4th and 5th numbers:

Median = (132 + 135) / 2 = 133.5

To find the quartiles, we need to divide the data set into four equal parts. Since there are 8 data points, the first quartile (Q1) is the median of the first half of the data set, and the third quartile (Q3) is the median of the second half of the data set.

Q1 = median of {106, 127, 129, 132} = (127 + 129) / 2 = 128

Q3 = median of {135, 138, 140, 158} = (138 + 140) / 2 = 139

The interquartile range (IQR) is the difference between the third quartile and the first quartile:

IQR = Q3 - Q1 = 139 - 128 = 11

Therefore,

The median is 133.5, the first quartile is 128, the third quartile is 139, and the interquartile range is 11.

Final answer:

The median of the given data set is 133.5, with the first quartile (Q1) at 128 and the third quartile (Q3) at 139. The interquartile range (IQR) is 11, and the range is 52.

Explanation:

To find the median, first quartile (Q1), third quartile (Q3), and interquartile range (IQR) of a set of data, we first need to list the data in ascending order. The given data is: 106, 127, 129, 132, 135, 138, 140, 158.

The median is the middle number when the data set is ordered. Since there are 8 numbers, the median will be the average of the 4th and 5th numbers: (132 + 135) / 2 = 133.5. So the median is 133.5

To find the first quartile, which is the median of the lower half of the data (excluding the median if the number of data points is odd), we look at the first four numbers: 106, 127, 129, 132. The median of this subset is (127 + 129) / 2 = 128. So Q1 is 128.

Similarly, Q3 is the median of the upper half of the data. For the numbers 135, 138, 140, 158, the median is (138 + 140) / 2 = 139. So Q3 is 139.

The IQR is the difference between Q3 and Q1, so IQR = 139 - 128 = 11.

The range of the data is the difference between the max and min values, which is 158 - 106 = 52.

Answer:

1/2x-5=13

Step-by-step explanation:

Let x= Frankie’s mother’s age

Half his mother’s age= 1/2x

5 less than that=1/2x-5

We know that Frankie is 13 so that equation is equal to Frankie’s age, which is 13.

Hope this helps.

To determine Franky's mother's age, we can create an equation using the given information. By solving the equation, we find that Franky's mother is 36 years old.

To determine Franky's mother's age, we can create an equation based on the given information. Let's assume Franky's mother's age is M. According to the information given, Franky's age is 5 years less than half of his mother's age. So, Franky's age can be represented as (1/2)M - 5.

We are also given that Franky is 13 years old. So we can set up the equation:

(1/2)M - 5 = 13

To solve for M, we can simplify the equation:

(1/2)M = 13 + 5

(1/2)M = 18

M = 18 * (2/1)

M = 36

Therefore, Franky's mother's age is 36 years old.

Answer:  B) 160

Step-by-step explanation:

Since the Standard deviation of 21 bins is 3 bins, then the first 7 bins falls in the first 2.5% edge of the bell curve.

2.5% of 21 times 1000 = (0.025)(21)(1000) = 160

let's bear in mind that 1 Cup = 8 fl oz.

a) is absolutely correct, 18oz and thus they can fit fine in the 24oz container.

b) is correct, 24 - 18 = 6, we can fit in 6 more oz, which is 3/4 of a cup.

c) is correct as well

d)

we just need to convert c) units to fluid ounces

[tex]\bf 2\frac{1}{4}\implies \cfrac{9}{4}\cdot 8\implies \boxed{18}~\hfill 3\cdot 8\implies \boxed{24} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{juice}}{18}+\stackrel{\textit{water}}{12}+\stackrel{\textit{ice cream}}{24}\implies 54~\textit{fluid ounces}[/tex]

Solving both equations individually, we derive n = -5 from the first and n < 2 from the second. No common solution exists due to the nature of these equations.

This problem involves two separate equations where you’re asked to find the value of n that satisfies both. We solve this by treating each equation individually.

First equation: -1 + 5n = -26

 To resolve for n we can simply add '1' to both sides, which result in: 5n = -25. Then divide both sides by '5' to isolate n, implying n = -5.

Second equation: 7n - 2 < 12

We will apply the same logic and add '2' to both sides, which gives 7n < 14. Afterwards, dividing through by '7', which gives us n < 2.

From these two solutions, there is no value of n that validates both equations simultaneously.

Answer: 432ft. shadow

Step-by-step explanation:

Because Nora is 5’3”, you need to convert every numerical value into inches by multiplying them by 12 (12in = 1 ft.)

5’ x 12 = 60” + 3” = 63”

9’ x 12 = 108”

252’ x 12 = 3,024”

Then create equivalent fractions.

63/108 = 3,024/x

108 x 3024 = 326,592/63 = 5,184in.

Then convert it back into feet.

5,184/12 = 432ft.

Final answer:

Using the proportion of similar triangles, we find that if Nora, who is 63 inches tall, casts a 108-inch shadow, then the 3024-inch tall monument will cast a shadow that is 5184 inches long, or 432 feet.

Explanation:

To find the length of the shadow casted by the monument, we can use the concept of similar triangles. The proportion between the heights and shadows of Nora and the monument will be the same because the angle of the sunlight is the same for both. Nora is 5'3" tall, which is 63 inches, and she casts a 9-foot shadow, which is 108 inches. The monument is 252 feet tall, which is 3024 inches. Setting up the proportion, we have:

Nora's height : Nora's shadow = Monument's height : Monument's shadow

63 inches : 108 inches = 3024 inches : x inches

To solve for x (the length of the monument's shadow in inches), we cross-multiply and divide:

63 * x = 3024 * 108

x = (3024 * 108) / 63

x = 5184 inches

To convert this back to feet, we divide by 12 inches per foot:

x = 5184 inches / 12 inches/foot

x = 432 feet

Therefore, the length of the shadow cast by the monument is 432 feet.

To find PK when PQ = QR, JK = 3x + 23, and LM = 9x - 19, you can add JK and LM together to get PK = 12x + 4.

Given that PQ = QR, JK = 3x + 23, and LM = 9x - 19, we can find PK by adding JK and LM together since they are all part of the same line. So, PK = JK + LM = (3x + 23) + (9x - 19). Now simplify the expression by combining like terms: PK = 3x + 9x + 23 - 19 = 12x + 4.

substitute in the equation

[tex]46=20x[/tex]

[tex]x=46/20[/tex]

[tex]x=\$2.3[/tex]

Answer:

$2.30

Step-by-step explanation:

We have been given that the amount of sales tax varies directly with the cost of the purchase.

We know that a direct variation in in form [tex]y=kx[/tex], where, y varies directly with x and k is constant of variation.

First of all, we will find constant of variation as:

[tex]\text{Sales tax}=k*\text{Cost of purchase}[/tex]

[tex]\$3.80=k*\$76[/tex]

[tex]\frac{\$3.80}{\$76}=\frac{k*\$76}{\$76}[/tex]

[tex]0.05=k[/tex]

To find the amount of sales tax on a purchase of $46, we will substitute [tex]k=0.05[/tex] in our equation as:

[tex]\text{Sales tax}=0.05*\$46[/tex]

[tex]\text{Sales tax}=\$2.30[/tex]

Therefore, the sales tax would be $2.30.

Step-by-step explanation:

I will be solving this questions in a rational, proportional way.

This question given is directly proportional. There are two types of proportion.

Direct - Let's say there are two values, x and y. In direct proportion, while x   increases, y increases with it.  

Inverse- Taking x and y, in inverse proportion, while x increases, y decreases or while y increases, x decreases.

In the given example, there are two values, number of plates and cost of plates. While the number of plates increases, the cost would surely increase. Therefore, giving us that it is a direct proportion.

500 plates : $18.00 :: 1 : $x

500 plates is to 18 dollars, then, 1 plate is to how many dollars?

In direct proportion, the product of extremes is equal to the product of means.

500(x) = 18(1)

x = 18 / 500

x = 0.036

Hence, one plate costs $0.036 or 3.6 cents

The phrase "eight times the sum of a number and 16 is at least -28" translates into the inequality 8(w + 16) >= -28. After solving, it shows that w must be greater than or equal to -19.5.

The student's question involves creating and solving an inequality. The inequality represents the phrase 'eight times the sum of a number and 16 is at least -28' and uses the variable w for the unknown number. The inequality in mathematical terms is:

8(w + 16) = -28

To solve the inequality, we first distribute 8 across the parenthesis:

8w + 128 = -28

Subtract 128 from both sides to get:

8w =-28 - 128

8w = -156

Now divide both sides by 8:

w = -19.5

This inequality shows that the number w must be greater than or equal to -19.5 to satisfy the original statement.

The solution to the inequality is [tex]\( w \geq -19.5 \)[/tex]

[tex]\[ w \geq \frac{-28 - 8 \times 16}{8} \][/tex]

[tex]\[ w \geq \frac{-28 - 128}{8} \][/tex]

[tex]\[ w \geq \frac{-156}{8} \][/tex]

[tex]\[ w \geq -19.5 \][/tex]

To solve this inequality, we'll first rewrite the given statement in mathematical terms. The problem states that "eight times the sum of a number and 16 is at least -28." Let's represent the unknown number by [tex]\( w \)[/tex]. According to the statement, we can write the inequality as:

[tex]\[ 8(w + 16) \geq -28 \][/tex]

To solve for [tex]\( w \)[/tex], we'll isolate it by performing operations to both sides of the inequality. First, we distribute the 8:

[tex]\[ 8w + 128 \geq -28 \][/tex]

Next, we'll subtract 128 from both sides to isolate the [tex]\( 8w \)[/tex] term:

[tex]\[ 8w \geq -28 - 128 \][/tex]

[tex]\[ 8w \geq -156 \][/tex]

Now, to solve for [tex]\( w \)[/tex], we divide both sides by 8:

[tex]\[ \frac{8w}{8} \geq \frac{-156}{8} \][/tex]

[tex]\[ w \geq -19.5 \][/tex]

So, the solution to the inequality is [tex]\( w \geq -19.5 \)[/tex]. This means that any number greater than or equal to -19.5 will satisfy the given condition. Therefore, the set of solutions is all real numbers greater than or equal to -19.5.

Answer:

A. 16

Step-by-step explanation:

We have to find rate of change of function from x=3 to x=5

The average rate of change for the interval a≤x≤b is given by:

Rate of change=  (f(b)-f(a))/(b-a)

In our question,

a=3

and

b=5

We can see from the table that at x = 3, the value of function is 18

So,

f(a)=18

and

At x=5, the value of function is 50

f(b)=50

Rate of change=(50-18)/(5-3)

=32/2

=16

So the rate of change of function between x=3 and x=5 is 16 ..  

Option A is the correct answer..
