Kyra sold a car that cost $26,500

1325 = 0.05x

1) 0.05x = 1325

2) Divide both sides by 0.05 -—> 0.05x/0.05 = 1325/0.05

3) x = 26,500

Final answer:

Kyra's commission of $1,325, which is 5% of the car's cost, leads us to calculate the cost of the car by dividing the commission by the commission rate, resulting in a car cost of $26,500.

Explanation:

Kyra receives a 5% commission on every car she sells. We are given that her commission on the last car she sold was $1,325. To find the cost of the car, we use the formula:

Commission = (Commission Rate) × (Cost of the Car)

Therefore,

Cost of the Car = Commission ÷ Commission Rate

Cost of the Car = $1,325 ÷ 0.05

Cost of the Car = $26,500

So, the car that Kyra sold was worth $26,500.

3.73 in expanded form

3 + 0.7+ 0.03

Final answer:

The number 3.73 in expanded form is written as 3 + 0.7 + 0.03, showing the value of each digit according to its place value.

Explanation:

The question is asking to write the number 3.73 in expanded form which is a way of writing numbers to show the value of each digit. When a number is written in expanded form, we break apart the number by each digit's place value, isolating each digit to represent the total sum of each part.

So, for the number 3.73, we can expand it as follows:

Now, combining these values together, we can write 3.73 in expanded form as:

3 + 0.7 + 0.03

Answer: I would say to go with "2-cup carton of pineapple juice for $1.04"

Step-by-step explanation:

Answer:

The time a student learns mathematics is important for their score

Step-by-step explanation:

Observe the boxes diagrams. Where the horizontal axis represents the score obtained by the students in the test.

The vertical lines that divide the boxes in two represent the value of the median.

The median is the value that divides 50% of the data.

For the class of the morning the value of the median is 50 points, with a maximum value of 80 and a minimum value of 10.

For the afternoon class, the median value is 65 points with a minimum value of 30 and a maximum value of 100.

This indicates that in general, the highest number of high scores were obtained in the afternoon class.

Therefore it can be said that the time a student learns mathematics is important for their  score

Answer Sorry if this is too late but the answer is yes because the median test score of the afternoon class is 15 points above the morning class other wise the first option

Answer:

(g+f)(x)=(2^x+x-3)^(1/2)

Step-by-step explanation:

Given  

f(x)= 2^(x/2)

And

g(x)= √(x-3)

We have to find (g+f)(x)

In order to find (g+f)(x), both the functions are added and simplified.

So,

(g+f)(x)= √(x-3)+2^(x/2)  

The power x/2 can be written as a product of x*(1/2)

(g+f)(x)= √(x-3)+(2)^(1/2*x)

We also know that square root dissolves into power ½

(g+f)(x)=(x-3)^(1/2)+(2)^(1/2*x)

We can see that power ½ is common in both functions so taking it out

(g+f)(x)=(x-3+2^x)^(1/2)

Arranging the terms

(g+f)(x)=(2^x+x-3)^(1/2)  ..

Final answer:

An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant. In this case, the recursive formula for the arithmetic sequence is A1 = 5 and An = An-1 - 4.

Explanation:

An arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant. In this case, the recursive formula for the arithmetic sequence is A1 = 5 and An = An-1 - 4. Let's find some terms in this sequence:

A1 = 5

A2 = A1 - 4 = 5 - 4 = 1

A3 = A2 - 4 = 1 - 4 = -3

A4 = A3 - 4 = -3 - 4 = -7

...

So the first few terms in this arithmetic sequence are 5, 1, -3, -7, ...

This is because that’s the smallest number in the multiple of both numbers.

Feynman, produces output, that is 5 times its input followed by an increase of 2.

i.e. the equation that will be formed using this information is:

                  [tex]f=5i+2------------(1)[/tex]

The output of Feynman feeds into Maxwell.

Let the output of Maxwell be denoted by m and it's input is f.

Maxwell, produces output, that is 5 times its input followed by a decrease of 2.

This means that the equation that will be formed using this information is:

             [tex]m=5f-2----------------(2)[/tex]

Now, we put the value of f from equation (1) into equation (2)

i.e.

[tex]m=5(5i+2)-2\\\\i.e.\\\\m=25i+10-2\\\\i.e.\\\\m=25i+8[/tex]

If the output of Maxwell is: 33

i.e.

The probability is 0.0015

Step-by-step explanation:

We know that the mean [tex]\mu[/tex] is:

[tex]\mu=6:30\ p.m[/tex]

The standard deviation [tex]\sigma[/tex] is:

[tex]\sigma=0:15\ minutes[/tex]

The Z-score is:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

We seek to find

[tex]P(x>7:15\ p.m.)[/tex]

The Z-score is:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

[tex]Z=\frac{7:15-6:30}{0:15}[/tex]

[tex]Z=\frac{0:45}{0:15}[/tex]

[tex]Z=3[/tex]

The score of Z = 3 means that 7:15 p.m. is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

So

[tex]P(x>7:15\ p.m.)=P(Z>3)=0.0015[/tex]

Answer:

Option A.) 88 inches

Step-by-step explanation:

step 1

Find the circumference of the wheel

we know that

The circumference of a circle is equal to

[tex]C=\pi D[/tex]

we have

[tex]D=28\ in[/tex]

[tex]\pi =\frac{22}{7}[/tex]

substitute

[tex]C=(\frac{22}{7})(28)=88\ in[/tex]

The distance a bicycle moves forward each time the wheel goes around is equivalent to the circumference of the wheel, which can be calculated using the formula C=πd. For a wheel with a diameter of 28 inches, the circumference is 88 inches.

The distance a bicycle wheel travels in one full rotation (which is also the perimeter of the wheel) can be calculated using the formula for the circumference of a circle, which is C=πd where π is a mathematical constant (about 22/7 or 3.14) and d is the diameter of the circle.

The diameter of this bicycle tire is given as 28 inches. Therefore, substituting 28 inches for the diameter (d) in the formula gives us C=22/7*28, which simplifies to 88 inches. So the bicycle moves forward approximately 88 inches each time the wheel goes around. Therefore, "the correct answer is A.) 88 inches".

P(x)=2(f+g)(x)

EXPLANATION

The perimeter of a rectangle is calculated using the formula:

P=2(l+w)

From the table

The length is f(x)=x+3

The width is g(x)=x+2

This implies that the perimeter is

P(x)=2(f(x)+g(x))

This is the same as

P(x)=2(f+g)(x)

The highest peak is in the middle and both sides of it are fairly similar, so this would be a bell shaped distribution.

Answer: [tex]x[/tex]≈[tex]0.732[/tex]

Step-by-step explanation:

You need to find the value of the variable "x".

To solve for "x" you need to apply the following property of logarithms:

[tex]log(m)^n=nlog(m)[/tex]

Apply logarithm on both sides of the equation:

[tex]90^x=27\\\\log(90)^x=log(27)[/tex]

Now, applying the property mentioned before, you can rewrite the equation in this form:

[tex]xlog(90)=log(27)[/tex]

Finally, you can apply the Division property of equality, which states that:  

 [tex]If\ a=b,\ then\ \frac{a}{c}=\frac{b}{c}[/tex]

Therefore, you need to divide both sides of the equation by [tex]log(90)[/tex]. Finally, you get:

[tex]\frac{xlog(90)}{log(90)}=\frac{log(27)}{log(90)}\\\\x=\frac{log(27)}{log(90)}[/tex]

[tex]x[/tex]≈[tex]0.732[/tex]
