My number is odd. It is a factor of 30 and a multiple of 3 what are my 2 numbers?
Answer:
3 and 15
Step-by-step explanation:
Factors of 30
30 = 2 , 3 , 5 , 6 , 10, 15
Odd numbers are: 3, 5, 15
Odd number & multiple of 3 are: 3 and 15
The required two odd numbers are 3 and 5.
We have to determine, It is a factor of 30 and a multiple of 3 what are 2 numbers.
To obtain the factor of 30 and 2 numbers is calculated in the following steps.
The Factors of 30 are,
30 = 2 , 3 , 5 ,
And multiply the terms by 2,
[tex]= 2\times 2 , \ 2 \times 3,\ 2 \times5 \\\\=4, \ 6,\ 10[/tex]
After multiply by 2 all the term become even.
Then,

how much is 50 cents in decimal
Answer:
0.50
Step-by-step explanation:
"Cents" generally refers to 1/100 of something. When it is money, it refers to 1/100 of the base unit of the currency. When it is land area, it refers to 1/100 of an acre.
__
In the US, 50 cents means 50/100 dollars, or $0.50.
In Europe, 50 cents means 50/100 euros, or €0.50.
In general 50 cents is 50/100 = 0.50.
A grocery store bought ice cream for $2.30per half gallon and stored it in two freezers. During the night, one freezer malfunctioned and ruined 14 half gallons. If the remaining ice cream is sold for $4.00 per half gallon, how many half gallons did the store buy if they made a profit of $97.00?
Answer:
number of half gallons of ice cream the store bought=90 half gallons
Step-by-step explanation:
given data
bought ice cream = $2.30 per half gallon
one freezer malfunctioned and ruined = 14 half gallons
ice cream is sold = $4.00 per half gallon
profit = $97.00
solution
we know here profit is express as
Profit = Money earned - Money spent ...................1
and we consider here total number of gallons bought = x
so Money earned = $4(x-14)
Money spent = $2.30(x)
so put here value and we get
$97 = $4(x-14) - $2.30(x)
solve it we get
x = 90
so number of half gallons of ice cream the store bought=90 half gallons

A particular movie theater charges $ 9.00 per adult ticket and $ 3.5 0 per child ticket. Suppose 550 people attended a movie and the total revenue from ticket sales was $ 3575 . Write two linear equations to represent a system to solve this, where x represents the number of adults attending the movie and y represents the number of children attending the movie. Write the equations, but do not solve them. The first equation must come from the information given about the total attendance and the second must come from the ticket prices and revenue. 1)= ? 2)= ?
Answer:
If x represents the no. of adults
and y represents the children, then
x + y = 550
9x + 3.50y = 3575
Answer:
Step-by-step explanation:
Number of children = y
Number of adults = x
Total people = 550
x + y = 550 ------------------ (I)
Charge for 'y' children =3.50 * y = 3.5y
Charge for 'x' adult = 9 * x = 9x
Total amount = $ 3575
9x + 3.5y = 3575 -------------(II)
Multiply equation (I) by (-9)
(I)*(-9) -9x - 9y = -4950
(II) 9x + 3.5y = 3575 { Now add and so 'x' will be eliminated}
- 5.5y = -1375
y = -1375/-5.5
y = 250
Plug in y = 250 in equation (I)
x + 250 = 550
x = 550 - 250
x = 300
Number of children = 250
Number of adults = 300

Answer:
The coordinates of S is [tex]( \frac{-3}{4}, \frac{1}{2})[/tex]
Step-by-step explanation:
We are supposed to find the coordinates of point S
Point S is 0.75 units to the left
So, x coordinate of point S = -0.75 = [tex]\frac{-3}{4}[/tex]
Now we are given that point S is 0.5 units up.
So, y coordinate of point S = 0.5 = [tex]\frac{1}{2}[/tex]
So, The coordinates of S is [tex]( \frac{-3}{4}, \frac{1}{2})[/tex]
So, Option A is true .

The function h(t) = 2.3 + 50t - 1.86t^2 models the height of an arrow shot from a bow on Mars, where h(t) is the height in metres and t is time in seconds. How long does the arrow stay in flight?
Answer:
The arrow stay in flight for 26.92 seconds
Step-by-step explanation:
We are given that the height of an arrow shot from a bow on Mars is modeled by equation:
[tex]h(t) = 2.3 + 50t - 1.86t^2[/tex]
Where h(t) is the height of arrow
t is the time in seconds
Now we are supposed to find How long does the arrow stay in flight?
Substitute h(t)=0
So,[tex]2.3+50t-1.86t^2=0[/tex]
[tex]1.86t^2-50t-2.3=0[/tex]
t=-.04 , 26.92
Since the time cannot be negative
So,the arrow stay in flight for 26.92 seconds

which answer describes the graph of the system of equations?
Answer:
D, the lines coincide.
Step-by-step explanation:
isolate the y so theres no 2y, only y:
2y = 8 - 2x (divide both sides by 2)
y = 4 - x
The lines are the same line, so while they are plural, they also coincide, as one lies on top of the other.

Answer:
-6
Step-by-step explanation:
from (-6,-4) to (x,8) there are already 12 spaces in between the y- axis from -4 to 8. So because there are already 12 spaces in between you dont need to add any space between x and -6 so you can conclude that if x is -6 then there will be 12 spaces inbetween because of -4 and 8
Study the diagram of circle B. Points C, R, and V lie on circle B. The radius, BC¯¯¯¯¯¯¯¯, and the diameter, VR¯¯¯¯¯¯¯¯, are drawn. Arc CR has a measure of 90∘. If m∠VBC=(3x+4)∘, what is the value of x?
Answer:
D. x ≈ 31.3°Step-by-step explanation:
The triangle CBV is angled triangle with right angle at ∠VBC.
Since ∠VBC = (3x-4) °
To get the value of x, we will equate the angle ∠VBC to 90°
This results into (3x-4) ° = 90
Simplifying the resulting equation;
3x-4 = 90
Adding 4 to both sides;
3x-4+4 = 90+4
3x = 94
Dividing both sides by 3
3x/3 = 94/3
x = 31.33°
x ≈ 31.3°

2 squared + (5*2) + 2 = 16
3 squared + (5*3) + 2 = 26

What is the domain of the function y=3/x-1?
O
-00
O-1
O 0
O 1
Answer:
x ≠ 1.
Step-by-step explanation:
In mathematics, anything divided by 0 is null. It is not valid. And so, in this case, x - 1 must never equal 0, but it can be any number other than 0.
x - 1 = 0
x = 1
That means that the domain of the function is x ≠ 1.

An NBA center recently signed a seven-year contract for $121 million. What is the present value of this contract, given a 9% interest rate? In other words, how much must the ball club invest when the contract is signed, so that it can make seven equal payments of $17285714.29, the first one due immediately?
Answer:
PV= $86,998,184.72
Step-by-step explanation:
Giving the following information:
Annual payments= $17,285,714.29
Number of years= 7
Interest rate= 9%
First, we need to determine the future value incorporating the interest rate.
FV= {A*[(1+i)^n-1]}/i
A= annual payment
FV= {17,285,714.29* [(1.09^7) - 1]} / 0.09
FV= $159,036,085.1
Now, we can calculate the present value:
PV= FV/(1+i)^n
PV= 159,036,085.1/1.09^7
PV= $86,998,184.72
