How to Write Out Number 0.801 in Words: eight hundred one thousandths in (US) American English, Number Converted (Spelled Out) to Words.

[] The equation on the left, 292 [tex]\frac{1}{2}[/tex]  = 18 * 6 [tex]\frac{1}{2}[/tex]  * h

-> Volume is length times width times height. When we plug in all the values we have to solve for h (height) we get this equation.

[] The height is 2.5 inches

-> We will solve the equation above.

-> Multiply 18 by 6 and a half = 117

-> Divide 292 and a half by 117 = 2.5

-> The height is 2.5 inches or 2 [tex]\frac{1}{2}[/tex]inches

292 [tex]\frac{1}{2}[/tex] = 18 * 6 [tex]\frac{1}{2}[/tex]  * h

292 [tex]\frac{1}{2}[/tex] = 117h

[tex]\frac{292 \frac{1}{2} }{117}[/tex]= [tex]\frac{117h}{117}[/tex]

2.5 = 1h

h = 2.5 inches

Answer:

5 gallons

conversion:

we have here total 80 cups.

80 cups → 40 pints

Then convert it into quartz

40 pints → 20 quartz

Then convert quartz into gallons

Answer:

50336

Step-by-step explanation:

The cost deprecates by 12% each year. If we have to find how much it deprecated for 2 years, we will have to calculate how much is 12% of the current price, subtract it, then find how much is 12% equal to again and subtract it once again. Not sure if that's the smartest way to do it though.
Anyway, we have
65000, 12% of 65000 is equal to (65000 * 12) / 100 = 650 * 12 = 7800
After the first year, the price will be:
65000 - 7800 = 57200

Now we do the same thing:
12% of 57200 = 57200 * 12% = 57200 * 12/100 = 57200 / 1 * 12/100 = (57200 * 12) / 100 * 1 = 572 * 12 / 1 = 572 * 12 = 6864
After the second year the price will be:
57200 - 6864 = 50336

Answer:

Step-by-step explanation:

Each intercept is found by setting the other variable to zero and solving for the variable value of interest.

  2x +3y = 54

x-intercept:

  2x = 54

  x = 27

y-intercept:

  3y = 54

  y = 18

__

By definition, the intercept values are the values that satisfy the equation when the other variable is zero.

x-intercept: To score 54 points, the team would have to make 27 2-point baskets if no 3-point baskets were made.

y-intercept: To score 54 points, the team would have to make 18 3-point baskets if no 2-point baskets were made.

The information given by the point of intersection of the two lines is (d) the number of copies for which the total cost per month is the same for both companies

The point of intersection is the equilibrium point of both companies.

This means that, the point represents where the number of copies and the total cost per month for both companies is equal

Hence, the information given by the point of intersection of the two lines is (d)

Answer:

500 bees

Step-by-step explanation:

The initial value is the y-intercept, where a point crosses the y-axis when x=0.

(0, x) = (0, 500)

Hope this makes sense :]

There are 500 bees in the population when it is first measured.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

It is a relation of the form y = aˣ  in mathematics, where x is the independent variable

Every week, a bee population is counted, and the findings are illustrated on the given graph.

According to the given graph, the initial value is the y-intercept, where a point intersects the y-axis when x = 0.

(0, x) = (0, 500)

This means the bee population is 500 when it is first measured.

Answer:

Step-by-step explanation:

x^3 + 3x^2 - 10x

~Factor

x(x - 2)(x + 5)

Solve for the zero.

x(x - 2)(x + 5) = 0

We know that; x = 0, x - 2 = 0, and x + 5 = 0

x = 0

x - 2 = 0

x = 2

x + 5 = 0

x = -5

Best of Luck!

Here we are provided with an polynomial of degree 3 and we have to factorise it first and then we have to compute it's zeroes.

Given Polynomial:

Taking common x from all the 3 terms,

➝ x(x² + 3x - 10)

Factorising through Middle term factorisation,

➝ x(x² + 5x - 2x - 10)

➝ x{x(x + 5) - 2(x + 5)}

➝ x(x - 2)(x + 5)

Hence, Factorised !!

Now equating to 0 to find the zeroes of the poly.

➝ x(x - 2)(x + 5) = 0

That means,

So, the zeroes of the polynomial is 0, 2 or -5

Step-by-step explanation:

a( Pr(no syntax error) = 1-Pr(syntax error arises)

Pr(no syntax error) = 1 -0.3

Pr(no syntax error) = 0.7

b) Pr(no error occurred) = 1-Pr(both error occurred)

Pr(no error occurred) = 1-0.1

Pr(no error occurred) = 0.9

c) Pr(any type of error occurred) = Pr(syntax error occur)+Pr(logical)

Pr(any type of error occurred) = 0.5+0.3 = 0.8

d) Pr(syntax and logical) = Pr(syntax occur)+Pr(logical or syntax occur)

= 0.3+0.1

= 0.4

e) Independent event are events that occurs at the same time. The occurrence of one does not affect the other.

Pr(logical and syntax) = pr(syntax)×pr(logical)

Given

pr(syntax)×pr(logical) = 0.3×0.5 = 0.15

From the question, Pr(logical and syntax) = Pr(both error occurred) = 0.1

Since Pr(logical and syntax) ≠ pr(syntax)×pr(logical), this means that the errors are not independent

4.9 miles

|| ✪ Solution ✪ ||

Step 1:

In this question, we are given the following:

Josiah wants to ride his bicycle 42.5 miles this week.

He has already ridden 18 miles. If he rides for 5 more days,

what is the average number of miles he would have to ride each day to meet his goal?

Step 2:

The details of the solution are as follows:

Total distance = 42. 5 miles

Distance ridden = 16 miles

Number of days left = 5 days

Let the number of miles that'll be ridden for each day be represented by x.

Hence, we have that,

[tex]5x+18=42.5[/tex]

[tex]5x=42.5-18[/tex]

[tex]5x=24.5[/tex]

Divide both sides by 5 we have that,

[tex]x=\frac{24.5}{5}[/tex]

[tex]x=4.9[/tex]

CONCLUSION:

The average number of miles he would have to ride each day to meet his goal =  4.9 miles

Hope this helps!

If you have any questions please ask.



The required average miles for him to ride for 5 days is 4.9 miles per day.

Given that,
Josiah wants to ride his bicycle 42.5 miles this week. He has already ridden 18 miles.
he rides for 5 more days, what is the average number of miles he would have to ride each day to meet his goal is to be determined

The average of the values is the ratio of the total sum of values to the number of values.

Here,
Josiah wants to ride his bicycle for a total of 42.5 miles,
he rides for 18 miles by now,
Remaining miles to ride = 42.5 - 18 = 24.5 miles
For 5 day is must ride for average = 24.5 / 5 = 4.9 miles per day.

Thus, the required average miles for him to ride for 5 days is 4.9 miles per day.

Answer: 9.77 cm

Step-by-step explanation:

The volume of the box is length x width x height (V = l*w*h). The area of the lid of the box is the length x width (A = l*w). So, to find the height, you can change the equation to volume / (length x width) = height (V/(l*w) = h). Divide the volume by the area (420/43), to get the answer of 9.77 cm.
