write an expression that mean "eight less than product of seven and X".​

Answer: 18.25

Step-by-step explanation: Lets start off with this: 1/4 is the same as 25 (like if you use quarters, you know 4 quarters makes a dollar, and one quarter is 25)

So, since we have 18 and 25, converting it to a decimal is easy. Put the numbers together (18 and 25) Then just add decimal in the middle.

                                                         OR

18 x 4 (which is 72) then add 72 to the numerator (1) which will give you 73 (72 + 1) Finally, divide 73 by 4, (4 is denominator) which will then give you 18.25 :D

The mixed number  [tex]18\frac{1}{4}[/tex]  written as a decimal is 18.25.

To write [tex]18\frac{1}{4}[/tex] as a decimal, we can convert the mixed number into an improper fraction and then divide the numerator by the denominator.

The mixed number to an improper fraction.

[tex]18\frac{1}{4}[/tex] = (18 × 4 + 1)/4

= 73/4

Divide the numerator by the denominator.

73 ÷ 4

= 18.25

Therefore,  [tex]18\frac{1}{4}[/tex]  written as a decimal is 18.25.

Answer: 1/3 of 24 tickets is 8

Step-by-step explanation:

1/3 of 24 is 8.

The way I usually find this is by multiplying different numbers by three and seeing if it equals (in this case) 24.

8 x 3 = 24

Because eight goes into twenty-four three times, eight is one-third of twenty-four.

Answer:

Future value, A = $642

Step-by-step explanation:

Given the following data;

Principal = $500

Interest rate = 5% = 5/100 = 0.05

Time, t = 5 years

n = 365

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 500(1 + \frac{0.05}{365})^{365*5}[/tex]

[tex] A = 500(1 + 0.000137)^{1825}[/tex]

[tex] A = 500(1.000137)^{1825}[/tex]

[tex] A = 500*1.2840 [/tex]

Future value, A = $642

Answer:

0.9398 = 93.98% probability that the student is not of Asian origin.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Business student

Event B: Not of Asian origin.

Probability that the student is an undergraduate majoring in business.

15% of 13%(Of Asian origin).

35% of 100 - 13 = 87%(Not of Asian origin). So

[tex]P(A) = 0.15*0.13 + 0.35*0.87 = 0.324[/tex]

Business student and not of Asian origin:

35% of 87%. So

[tex]P(A \cap B) = 0.35*0.87 = 0.3045[/tex]

One undergraduate student majoring in Business is randomly selected from this university. Find the probability that the student is not of Asian origin.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.3045}{0.324} = 0.9398[/tex]

0.9398 = 93.98% probability that the student is not of Asian origin.

Answer:

342.5 + 65.25 = C

407.75 = C

Step-by-step explanation:

Given that the total cost of Kurt's required textbooks this quarter is $ 342.50, while optional textbooks cost a total of $ 65.25, to determine which inequality shows the total cost C that Kurt could pay for his textbooks, the following mathematical reasoning must be performed:

Mandatory books + optional books = Cost

342.5 + 65.25 = C

407.75 = C

Thus, Kurt could pay a total cost of $ 407.75 for his textbooks this quarter.

Answer:

1100 mm = 1.1 m, and 900 mm = 0.9 m.

So the area is 1.1 x 0.9 = 0.99 m^2

The area of the rectangular board is 0.99 square meters.

Given that a rectangular board is 1100 millimeters long and 900 millimeters wide.

We need to find the area of the board,

To find the area of the rectangular board in square meters, we need to convert the given dimensions from millimeters to meters and then calculate the area.

Given:

Length of the board = 1100 millimeters

Width of the board = 900 millimeters

To convert millimeters to meters, we divide the given values by 1000:

Length in meters = 1100 mm / 1000 = 1.1 meters

Width in meters = 900 mm / 1000 = 0.9 meters

The formula to calculate the area of a rectangle is:

Area = Length × Width

Substituting the values, we get:

Area = 1.1 meters × 0.9 meters

Area = 0.99 square meters

Therefore, the area of the rectangular board is 0.99 square meters.

x-y=3

x-(15-x)=3

1. 10

2. 14.1421

3. 8

4. 6.9282

Step-by-step explanation:

To find 1, you need to use tangent. Let's say the missing side is x. You need to use tan(45) = x/10 to be able to solve. If you don't know how to do that, you just need to multiply by 10 on both sides, that way the 10 cancels out and all you get is x. Tan(45) multiplied by 10 is 10.

Now, find 2 with sine. The equation is sin(45) = 10/x. First, you need to multiply both sides by x so you get 10 alone. Now, divide both sides by sin(45) to cancel out the left side and get the answer to 2. 10/sin(45) = 14.1421 (I don't know if you need to round).

To find 3, you need to use cosine. The equation would be cos(60) = 4/x. Again, multiply both sides by x to get 4 alone. Next, divide both sides by cos(60). 4/cos(60) is 8.

To find 4, you need to use sine again. The equation is sin(60) = x/8. Multiply both sides by 8, and there's your answer. 6.9282.
