Answer:
[tex]\boxed {\boxed {\sf 7.5 \ feet}}[/tex]
Step-by-step explanation:
We are given this function for the height (h) after t seconds:
[tex]h=-16t^2+25t+6[/tex]
Seconds is t and we want to find the height after 1.5 seconds. Plug 1.5 in for t.
[tex]h= -16(1.5)^2+25(1.5)+6[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Solve the exponent first.
(1.5)²= 1.5*1.5=2.25[tex]h= -16(2.25)+25(1.5)+6[/tex]
Multiply.
[tex]h= -36+25(1.5)+6[/tex]
[tex]h= -36+37.5+6[/tex]
Add.
[tex]h=1.5+6=7.5[/tex]
This is already rounded to the nearest tenth, so it is the answer.
After 1.5 seconds, the basketball is at a height of 7.5 feet.

Step-by-step explanation:
Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca. Is he correct, if the sandwich sizes are different.
Answer:
Riley is correct
Step-by-step explanation:
Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca.
To find out the fraction of how much more Riley ate than Luca, we carry out Subtraction operation
= Fraction of what Riley ate - Fraction of what Luca ate
= 5/6 - 3/6
Lowe's Common Denominator = 6
= 5 - 3/6
= 2/6
Therefore, Riley is correct
Every summer, Lacey goes on a week-long canoe trip with her childhood camp friends. After
the trip, she usually purchases some oars from the destination city. Her collection of oars is
organized by year and type of wood.
Answer:
5/18
Step-by-step explanation:
So sorry if this is wrong but to find the probability you must add all of your things (oars) together then find what the chance of getting that is so 4 oak 5 ash in 2010+4 oak and 5 ash in 2011 is 18 oars total and there was 5 ash in 2011 so the answer is 5/18
Solve for the missing arcs
Answer:
Step-by-step explanation:
arc KL = 60°
arc LNK = 360° - 60°
arc NJK = 180°
angle JQN = 60°
arc JN = 60°
arc JM = 60°+55° = 115°
arc MN = 55°
arc MKN = 360° - 55° = 305°
arc JML = 180°
angle MQL = 180° - 55° - 60° = 65°
arc ML = 65°
arc LN = 55° + 65° = 120°

Step-by-step explanation:
Ms. Peters has 36 red, blue, and green markers. She has an equal number of
each color of marker. She arranges the red markers in 2 equal groups. How
many red markers are in each group?
18
9
6
12
Answer:
6 markers
Step-by-step explanation:
1) Find the number of red markers
Firstly, we know that Ms. Peters has a total of 36 markers. There are 3 colours within these 36 markers. Because she has an equal number of each colour, divide 36 by 3 to find the number of red markers.
36÷3=12
Therefore, Ms. Peters has 12 red markers.
2) Find the number of red markers in each group
Ms. Peters then divides the red markers into 2 equal groups. Because we now know that there are 12 red markers, divide 12 by 2 to find this number.
12÷2=6
Therefore, there are 6 red markers in each group.
I hope this helps!
150 people attend a play.
45 of them are male.
Write the ratio male : female in its simplest form.
Answer:
Step-by-step explanation:
If 150 people attend and 45 are male.
females=150-45=105 so
m:f=45:105 (the gcf is 15 so we simplify by dividing each term by 15)
m:f=3:7

A jar has marbles in it. Three tenths of the marbles are red. Five tenths of the marbles are blue.
Two tenths of the marbles are green. Which of these fractions is equivalent to four eighths?
The red marbles are 3/10 of the total.
The blue ones are 5/10 of the total.
The green ones are 2/10 of the total.
Of these, 5/10=1/2=(1×4)/(2×4)=4/8
Therefore, five tenths is equivalent to four eighths.

Avah was reading a 675 page novel, at a rate of 35 pages per hour.
a. Write an equation to represent the number of pages left to read ,N, and the number of
hours,h, Avah has been reading.
Answer:
N = 675 - 35h
Step-by-step explanation:
She reads 35 pages per hour.
In 1 hour, she reads 35 * 1 pages.
In 2 hours, she reads 35 * 2 pages.
In h hours, she reads 35 * h, or 35h, pages.
The book has 675 pages. The number of pages left to read is the total number of pages minus the pages she already read.
The number of pages left to read is 675 - 35h.
Equation:
N = 675 - 35h
Earl earned $356 in gross pay. He had
$27.23 deducted for FICA taxes and $52.69
deducted for state and federal taxes. What
percent of his gross pay did he take home?
Answer:
77.5506% I believe is the answer unrounded.
77.55% rounded to the nearest hundredth.
77.6% rounded to the nearest tenth.
Step-by-step explanation:
356 = 100%
(356 - 27.23) - 52.69
328.77 - 52.69
276.08
what is the slope of 2x-4y=5
Answer:
1/2 or .5
Step-by-step explanation:
Hey There!
So the first step of this problem is to get y on one side and everything else on the other side
to do so we use inverse operations
so to get rid of the 2x we subtract 2x from each side
we would end up with -4y=5-2x
now want to get rid of the -4 on the y
to do so we would divide each side by -4
we would end up with
[tex]y=\frac{1}{2}x -\frac{4}{5}[/tex]
so we can conclude that the slope is 1/2 or .5

Answer:
28260 cubic cm
Step-by-step explanation:
Given,
Diameter of the cylinder = 30cm
So, radius of the cylinder = 30cm ÷2 = 15 cm
Height of the cylinder = 40 cm
There, volume of the cylinder,
[tex] = \pi {r}^{2} h[/tex]
[tex] = 3.14 \times 15cm \times 15cm \times 40cm[/tex]
[tex] = {28260cm}^{3} [/tex]
Answer:
diameter=30cm
radius=30/2=15
volume of cylinder = pi×r²×h
volume of cylinder=3.14×15²×40cm
volume of cylinder=28,260cm³

Simplify. Your answer should contain only positive exponents.
Answer:
[tex]\frac{1}{4k^3}[/tex]
Step-by-step explanation:
It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as [tex]k*(4k^{4})^{-1}[/tex] or [tex]k*4^{-1}*k^{-4}[/tex] The question asks for positive exponents though so yu don't need to do that.
You also need to know [tex]\frac{x^a}{x^b}=x^{a-b}[/tex] so in this case [tex]\frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}[/tex]
so [tex]\frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}[/tex]
