Final answer:

The number 28.93 in expanded form is written as 20 + 8 + 0.9 + 0.03.

Explanation:

The number 28.93 in expanded form is written as 20 + 8 + 0.9 + 0.03. To expand a decimal number, we break it down into its place values, where each digit is represented by its value in terms of tens, ones, tenths, hundredths, and so forth. In the case of 28.93, the '2' is in the tens place and represents 20, the '8' is in the ones place and represents 8, the '9' is in the tenths place and represents 0.9, and the '3' is in the hundredths place and represents 0.03.

We group similar terms to get:

-12n+30n=-10+12-2

We simplify to get:

18n=0

Divide through by 18 to get:

n=0

Answer:0.434

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = 3x - 4  (1)

4x + 3y = 1 (2)

if we substitute y by 3x - 4 in the second equation we get

4x + 3(3x-4) = 1 ⇒ 4x + 9x - 12 = 1 ⇒ 13x = 13 ⇒ x = 1

now ,we substitute x by 1 in the first equation

y = 3(1) - 4 = 3 - 4 = -1

Width of the miniature model = [tex]3\frac{3}{4}[/tex] inches

Length of the miniature model = [tex]5\frac{1}{2}[/tex] inches

The actual width of the boat = 15 feet

Let us find the actual length of the boat.

Write it in a proportion form.

width of model : length of model : : width of actual : length of actual

[tex]$\Rightarrow 3\frac{3}{4}:5\frac{1}{2}::15:x[/tex]

[tex]$\Rightarrow\frac{15}{4}:\frac{11}{2}::15:x[/tex]

[tex]$\Rightarrow\frac{\frac{15}{4}}{\frac{11}{2}} =\frac{15}{x}[/tex]

Do cross multiplication.

[tex]$\Rightarrow{\frac{15}{4}x =15\times\frac{11}{2}[/tex]

[tex]$\Rightarrow{\frac{15}{4}x =\frac{165}{2}[/tex]

[tex]$\Rightarrow x =\frac{165}{2}\times{\frac{4}{15}[/tex]

⇒ x = 22

Hence the actual length of the boat is 22 feet.

Answer:

0.4, 2/5

Step-by-step explanation:

The probability that Juan has to wait more than 15 minutes is 0.4 and the probability that Juan doesn't have to wait for more than 15 minutes is 0.6

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening being equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here, there is a 40% chance that he will have to wait more than 15 minutes. Thus the probability of him waiting for more than 15 minutes is 0.4 and the probability that he has to wait less than 15 minutes is 1-0.4=0.6

Hence, P(<15)=0.6 or 3/5 and P(>15) = 0.4 or 2/5 are the  probabilites for Juan

Final answer:

The value of 4x when x=4 is 16, and for proportions like 1:2=4:x, you'd get x=8 by cross multiplying.

Explanation:

The value of 4x when x=4 is simply 4 multiplied by 4, which equals 16. This calculation is a basic algebraic operation, and it should not be confused with more complex problems. For example, if you're trying to solve a proportion like 1:2=4:x, you'd set up a proportion to figure out the value of x. To solve for x you can use the cross multiplication method, resulting in 1x = 8, hence x = 8.

Final answer:

The value of 4x^3 + 4x when x=4 is found by substituting 4 into the expression and simplifying step by step, resulting in a final answer of 272.

Explanation:

When answering a question such as "What is the value of 4x3 + 4x when x=4," we need to substitute the value of x into the expression and simplify.

Let's break it down step-by-step:

Substitute x with 4 into the expression: 4(4)3 + 4(4).

Calculate the exponent: (4)3 = 4 x 4 x 4 = 64.

Multiply by 4: 4 x 64 = 256.

Add the second term: 256 + 4(4).

Perform the second multiplication: 4 x 4 = 16.

Add the two results together: 256 + 16.

Get the final answer: 272.

Sylvia has completed 9 laps.

Step-by-step explanation:

Step 1; Sylvia runs for a total of 2000 meters. Each lap is 200 meters long.   To find the number of laps remaining we need to know the total distance, the distance already covered and the distance on each lap. The distance left to run is equal to the total distance to be run - the distance already ran = 2000 - 1800 meters = 200 meters.

Step 2; The number of laps remaining = The distance left to run/distance on each lap.

The number Number of laps remaining = 200 meters/200 meters

The number of laps remaining = 1 lap.

Final answer:

To determine the number of laps a runner has completed when given the remaining distance to run and the length of each lap, multiply the number of laps by the length of one lap. Answer is 9 laps.

Answer:

312016 is your correct answer

Step-by-step explanation:

answer:

99.43

Step-by-step explanation:

because there is a 0.57 chance something will not happen, we will fill the rest of the equation in with 100 percent subtracted by 0.57 to get 99.43. Therefore, 99.43 is the correct answer.

Final answer:

To find the probability of an event happening when the probability of it not happening is 0.57, subtract 0.57 from 1, resulting in 0.43.

Explanation:

The probability that an event will not happen is given as P(E) = 0.57. To find the probability that the event will happen, we use the formula P(A) + P(~A) = 1, where P(A) is the probability of the event happening and P(~A) is the probability of the event not happening. The probability of the event happening, therefore, is 1 - P(E) = 1 - 0.57 = 0.43.

To find out how much Tina needs to run each day, divide the total miles she wants to run by the number of days. The result is that Tina needs to run 1.8 miles each day.

To find out how far Tina must run each day, we need to divide the total distance she plans to run by the number of days she plans to run. Tina wants to run 12 3/5 miles over 7 days. As a first step, convert her mixed number to an improper fraction. 12 3/5 is equivalent to 63/5.

Now, to find the distance she must run each day, simply divide 63/5 miles by 7 days. Carrying out this division gives us distance of 9/5 miles per day, or in decimal form, 1.8 miles per day.

So, Tina should run 1.8 miles each day to reach her goal.
