Find the volume of the triangular pyramid to the nearest whole number (number only in your answer) Please help....
Answers
Answer:
Volume of pyramid = 317 units³
Step-by-step explanation:
Volume do triangular pyramid = ⅓ × Base Area × height of pyramid
Base area = ½*bh = ½*8*14 = 56 units²
Height of pyramid = 17
Volume of pyramid = ⅓ × 56 × 17
Volume of pyramid = 317 units³ (to nearest whole number)
Answer:
Step-by-step explanation:
Volume of the triangular pyramid=1/3 Bh
B=area of the triangular base, B=1/2 bh=1/2 (14(8)=56
h= height of the pyramid =17
V=1/3 Bh =1/3 (56) (17)=317.33

How many identification numbers are possible?
Answers
Answer:
1,000,000,000 identification numbers are possible.
Step-by-step explanation:
We are assigned a 9 digit identification number.
Each digit is a number from 0 to 9. So, each digit has 10 different choices.
Using the Fundamental Counting Principle (is better than the tree diagram) because it's simpler. To illustrate this, we can attempt to draw a tree diagram.
The first column will be the digits 0 to 9.
Then for each of those digits, we need another 0 to 9.
As you can imagine, the amount of numbers grow exponentially, so using the Fundamental Counting Principle is simpler.
And since we have a 9 digit identification number, with each digit having 10 choices, the total number of identification numbers possible are:
[tex]10\times 10\times 10 \times 10\times 10 \times 10 \times 10 \times 10 \time 10\times 10=10^9=100000000[/tex]
So, 1,000,000,000 identification numbers are possible.

Which number line can be used to find the distance between (4, -1) and (8, -1)?
Answers
Answer:
I am not sure, but I believe it is the last one. Sorry if it's not right.
Answer:
The first number line
Step-by-step explanation:
Hey There!
The answer is the first number line because the y values in the given coordinates are the same so all we have to do is plot the x values (4 and 8) and we can find the distance between the two points. The first number line has 4 and 8 on it therefore that is the answer.

You deposit $400 in an account earning 6% interest compounded annually. How much will you have in the account in 10 years?
Answers
Answer:

Step-by-step explanation:
The Simple formula for compound interest:
[tex]P(1+\frac{r}{100} )^t[/tex]
P = Principle Amount
r = Rate
t = Time
Substituting the numbers into the formula:
[tex]400(1+\frac{6}{100} )^{10}[/tex]

The surface area of a regular triangular pyramid is 197.1 square meter. The slant height is 12. The area of the base is 35.1 square meters. The base length is 9 meters. What is the height of the triangular base?
Answers
Answer:
h = 7.8
Step-by-step explanation:
A = 1/2*b*h
35.1 = 1/2*9*h . . . . dimensions apply to the base only
35.1*2/9 = h = 7.8 . . . m is the height of the triangular base.
Check:
The base is an equilateral triangle, so the height will be (9 m)*sin(60°) = 7.8 m.

For the question asked, the surface area and slant height are irrelevant.

On what day of the year 2009 was the year 250 000 minutes old? Give the month and day????
Answers
=========================================================
Explanation:
1 hour = 60 minutes
1 day = 24 hours
1 day = (24 hrs)*(60 min/1hr) = 24*60 min = 1440 min
1 day = 1440 min
Divide 250,000 minutes over 1440 min to convert from minutes to days
(250,000)/(1440) = 173.611
This means 250,000 minutes is approximately 173.611 days.
We round this down to the nearest whole number because 174 full days means that some portion of minutes has not elapsed just yet. In other words, we're still on day 173. Yes we're past the halfway point, but we're still on this day.
From here, bring out a Day-Of-Year Calendar which will help you locate any day of the year if you know its numeric value, and vice versa. For instance, if you selected any value between 1 and 31, then you'll be on January of that day number. If you selected 32, then you'll be on February 1st since day 32 is one day after day 31 (the last day in January). The largest value of the calendar is either 366 on leapyears or 365 for non-leapyears.
Keep in mind that 2009 is not a leapyear, so that means we won't be involving Feb 29. On non-leapyears, the 173rd day lands on June 22nd.
You could count out the number of days from Jan 1st until you count out 173 days (you should land on June 22). Though I don't recommend this method because it could be error prone and slow.
------------
Side note: Day-Of-Year Calendars are useful if you want to know the timespan between any two days of the year. For instance, June 22 is the 173 day of the year while Oct 9th is the 282 day of the year (I'm focusing on a non-leapyear). The difference in value is 282-173 = 109, meaning that 109 days elapse from June 22 to Oct 9.

Answers
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Areas and Volumes.
We know that, Area of a Rectangle = length * Width.
Since,here Length = 6 inch and Area = 54 square inches,
==> Width = Area / length
==> Width = 54/6
=> Width = 9 inches.
Hence the width of the rectangle is 9 inches.

Two families went to Rollercoaster World. The Garcia family paid $170 for 3 children and 2 adults. The McGruder family paid $360 for 4 children and 6 adults.
If x is the price of a child’s ticket in dollars and y is the price of an adult’s ticket in dollars, write a system of equations the models this situation.
Answers
Answer:
3x +2y =170 ---equation 1
4x +6y =360 ---equation 2
Price of child 's ticket =$30
price of an adult’s ticket =$40
Step-by-step explanation:
Let x represent the price of a child’s ticket in dollars
and y represent the price of an adult’s ticket in dollars
Such that
3 children and 2 adults for the cost of $170 be represented as
3x +2y =170 ---equation 1
4 children and 6 adults for the cost of $360 be represented as
4x +6y =360 ---equation 2
3x +2y =170 ---equation 1
4x +6y =360 ---equation 2
bY Elimination method Multiplying equation 1 by 4 and equation 2 by 3
12x+8y =680---equation 3
12x +18y =1080---equation 4
Subtracting equation 3 from 4
10 y=400
y =400/10
y=40
Puting the value of y=40 in equation 1 to foind x
3x +2y =170
3x+2 x 40= 170
3x+80 =170
3x=170-80
3x=90
x=90/3=30
Price of child 's ticket =$30
price of an adult’s ticket =$40
