What is the average speed of a soccer ball that travels 34 m in 2 s? Wright in 3 Sentences.
Also, How long would it take a bus traveling at 52 km/h to travel 130 km? Answer in 3 sentences.
Answer:
1). The average speed is 17 mps (m per second). I know this because if you divide 34 m by 2, (in order to get the m per second) you will get 17 mps. Thats how i got my answer.
2). It would take 2.5 hours to travel 130km. I know this by dividing 139 by 52. I chose to do this because if you travel 52km/h, then dividing 130km by 52 will give you an answer
Mary has 3636 flower pots. She plants daisies in \frac{2}{3} 3 2 of her flower pots. In how many flower pots does Mary plant daisies? Use paper to show your work. Enter your answer in the box.
Answer: 24
Step-by-step explanation:
Number of flower pots = 36
Since she plants daisies in 2/3 of her flower pots, the number of flower pots that Mary plant daisies will be:
= 2/3 × 36
= 2 × 12
= 24
She plants daises in 24 flower pots

There are 18 girls on the swim team and 12 boys on the swim team what percent of the team is made up of boys
Answer:
40%
Step-by-step explanation:
So add 18 and 12 makes 30. Then divide 30 with a common factor say 6. so there is 5 6s in 30 so each 6 is equivalent to 20 percent there are 2 6s in 12 so it is 40 percent

the width if a rectangular room is 1 less than twice the length if the perimeter is 196 feet how long is the length
Answer:
l = 33 feet
Step-by-step explanation:
Let length be l.
Width, b = 2l-1
Perimeter of the room, P = 196
We know that the perimeter of the rectangle is given by :
P = 2(l+b)
196=2(l+2l-1)
98=3l-1
Adding 1 both sides.
98+1=3l-1+1
3l=99
l = 33 feet
So, the length of the room is 33 feet.
A person places $3610 in an investment account earning an annual rate of 6.6%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 18 years.
Answer:
11842.6541≈11842.65
Step-by-step explanation:
The amount of money to the nearest cent in the account after 18 years is
$11842.75.
What is Continuous compounding?Continuous compounding is the mathematical limit that compound interest can reach if it's calculated and reinvested into an account's balance over a theoretically infinite number of periods. While this is not possible in practice, the concept of continuously compounded interest is important in finance. It is an extreme case of compounding, as most interest is compounded on a monthly, quarterly, or semiannual basis.
A = P × [tex]e^{rt}[/tex]
where,
A = Amount of money after a certain amount of time
P = Principle or the amount of money you start with
e = Napier’s number, which is approximately 2.7183
r = Interest rate and is always represented as a decimal
t = Amount of time in years
Given here,
Principal amount (P) = $3610,
Interest rate (r) = 6.6% = 6.6/100 = 0.066
Amount of time (t) = 18 years
Therefore, Amount after 18 years will be A = P × [tex]e^{rt}[/tex]
A = $3610 × [tex]2.7183^{0.066 *18}[/tex]
A = $3610 × 3.2805
A = 11.842.7482
A = $11842.75
Hence, The amount of money to the nearest cent in the account after 18 years is $11842.75

15y = 45x + 60
What is the slope
6y=12x + 36
What the slope
Answer:
12 that's what I think the answer is
Answer:
3 and 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
15y = 45x + 60 ( divide all 3 terms by 15 )
y = 3x + 4 ← in slope- intercept form
with slope m = 3
Given
6y = 12x + 36 ( divide all 3 terms by 6 )
y = 2x + 6 ← in slope- intercept form
with slope m = 2

7(2x+5) = 11x-9-x
How would you verify or check your answer when x=-11 pls HELP]
9514 1404 393
Answer:
put the value into the equation and do the arithmetic
Step-by-step explanation:
As with any checking, you put the value where the variable is and do the arithmetic.
7(2x +5) = 11x -9 -x
For x = -11
7(2(-11) +5) = 11(-11) -9 -(-11)
7(-22 +5) = -121 -9 +11
7(-17) = -119
-119 = -119
The value x = -11 makes the equation true.
1. Remember what we know about vertical angles and solve for X.
(4x-7)
(3x+2)
Answer:
Step-by-step explanation:
Both will be equal ,
4x-7 =3x +2
solve it we will get ,
x =9 degree
Answer:
answer is x=9
vertical angles have same angle measure.
so:
(4x-7)=(3x+2)
x=9
lets see if it correct. put x values in
4×9-7=3×9+2
29=29

Answer
a) correct
b) (30, 100) would mean an area of 100 square feet is enclosed when the width is 30 feet. (Kristina's vertex coordinates are incorrect.)
Step-by-step explanation:
a) The derivation and expression for A(w) are correct
__
b) Kristina made a mistake in using her graphing calculator to find the vertex. The actual vertex is (27.5, 756.25). The coordinates of the vertex are (w, A(w)). The vertex (w, A(w)) means that the area of the enclosed space is A(w) when the width of the enclosure is w.
If Kristina's vertex coordinates were correct (which they are not), they would tell you the enclosed area is 100 square feet when the width of the enclosure is 30 feet.
Spencer has a bank account with a balance. Of. $75.Spencer owes$30 to her credit card and she owes $50 for a LCD tv.What would spencers bank balance be,if both debits were paid.
Answer: $-5
Step-by-step explanation:
From the question, we are informed that Spencer has a bank account with a balance of $75.
We are further told that Spencer owes $30 to her credit card and she owes $50 for a LCD tv.
The amount on Sencers bank balance if both debits were paid would be:
= $75 - ($30 + $50)
= $75 - $80
= $-5
