Suppose you drop a ball from 120 feet. The ball will bounce to 25 of its previous height. What is the total distance the ball travels from when you let it go to the max height it reaches after the 5th bounce? Round to the nearest tenth.
A) 268.7
B)273.9
C)277.1
D)279.3
Answer:
277.1 feets
Step-by-step explanation:
Drop height = 120 feets
Ball bounces 2/5 of previous height
Height after 1st bounce :
120 * 2/5 = 48 feets
Return distance = 48 feets
Height after second bounce :
48 * (2/5) = 19.2 feets
Return distance = 19.2 feets
Height after 3rd bounce :
19.2 * (2/5) = 7.68 feets
Return distance = 7.68 feets
Height after 4th bounce :
7.68 * (2/5) = 3.072 feets
Return distance = 3.072 feets
Height after 5th bounce :
3.072 * (2/5) = 1.2288 feets
(120 + (2*48) + (2*19.2) + (2*7.68) + (2*3.072) + 1.2288) = 277.1328
= 277.1 feets

In the data set below, what are the lower quartile, the median, and the upper quartile? 626676848497 lower quartile = median = upper quartile =
Answer:
Q1 = 4
Q2 = 7
Q3 = 42. 75
Step-by-step explanation:
Given the data:
626676848497
6, 2, 66, 7, 6, 8, 4, 8, 49, 7
Arrange in ascending order :
2, 4, 6, 6, 7, 7, 8, 8, 49, 66
The lower quartile (Q) :
1/4(n+1)th term
n = number of sample = 10
1/4(11)th term
2.75 term : (2 + 6) /2 = 8/2 = 4
Median :
1/2(n+1)th term
n = number of sample = 10
1/2(11)th term
5. 5 term : (7 + 7) /2 = 14/2 = 7
Upper quartile :
3/4(n+1)th term
3/4(11)th term
8.25 th term
3 /4 (8 + 49) = 42.75

Anthony invested $1000 in a savings account at 2% simple interest. He invested the money for 4 years.
What is the total amount Anthony will have at 4 years?
Answer:
80
Step-by-step explanation:
find 2 percent of 1000 and times it by 4 the amount of years
Answer:
$1082.43
Step-by-step explanation:
You use the interest formula.
P(1+r/n)^nt
Then plug it in
1000(1+.02)^4
Which comes out to 1082.43

Group of answer choices
55 in sq
150 in sq
24 in sq
27.5 in sq
Answer:
answer: 150 in sq
Step-by-step explanation:
All we have to do to these is multiply 2.5 by the base and height then multiply base × height so 2.5 × 8 = 20 2.5 × 3 = 7.5
20 × 7.5 = 150 Hope this helps!

I have the same question but with one more number.

30 or 15? (i dont know, maybe look at the other answer?)
Step-by-step explanation:
e) The diagonal of square A, marked off by the red stars, is where the concession stand is located. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning.
Answer:
60 ft long bc that would leave 10ft on each side of the banner...Step-by-step explanation:
Hopes this helps. Mark as brainlest plz!Answer:
Solution given:
length [l]=breadth [b]=40ft
Now
length of concession banner[h]=?
we have
perpendicular [p]=base[B]=40ft
by using Pythagoras law
h²=p²+b²
h²=40²+40²
h=√3200
h=40√2
So
the length of the concession stand to determine if the school banner can fit across the length of the concession stand is 40√2 ft or 56.57ft
solve the system by substitution
5x+y=-14
5x- 3y=2
Answer:
x = -2, y = -4, or (-2, -4).
Step-by-step explanation:
5x + y = -14
5x - 3y = 2
If we look at the first equation, we can see that y can be easily isolated.
5x + y = -14
Subtract 5x from both sides.
y = -5x - 14
Now we have a variable that we can plug into the second equation.
5x - 3y = 2
5x - 3(-5x - 14) = 2
Distribute the -3 across each term in the parentheses.
5x + 15x + 42 = 2
Combine like terms.
20x + 42 = 2
Subtract 42 from both sides.
20x = -40
Divide both sides by 20 to isolate x.
x = -2
Plug in x = -2 back into one of the equations to find y.
y = -5x - 14
y = -5(-2) - 14
Multiply.
y = 10 - 14
Subtract.
y = -4
Our solution is x = -2, y = -4, or (-2, -4).
Check your answer by plugging both values into one of the equations.
5x - 3y = 2
5(-2) - 3(-4) = 2
-10 + 12 = 2
2 = 2
Your answer is correct.
Hope this helps!

15 points
[tex] \sqrt{(3 + 2) ^{2} } [/tex]
Step-by-step explanation:
Given :-
(√3+√2)²√{(3+2)²}And we need to simplify the given numbers . We can use a identity in 1st Question as ,
[tex]\implies (a+b)^2=a^2+b^2+2ab[/tex]
Simplifying first :-
[tex]\implies (\sqrt3+\sqrt2)^2\\\\\implies (\sqrt3)^2+(\sqrt2)^2+2.\sqrt3.\sqrt2 \\\\\implies 3+2+2\sqrt6=\boxed{\red{5+\sqrt6 }}[/tex]
Simplifying second :-
[tex]\implies (3+2)^2\\\\\implies 5^2\\\\\implies \boxed{\red{25}}[/tex]
Approximate the distance between (0, -5) and (4, 1) to the nearest tenth, if necessary.
Answer:
7.7
Step-by-step explanation:
To solve this question we must use Pythagoras (a²+b²=c²) Let those two dots be A and B respectively.Imagine a line is drawn that pases through both dots,
Imagine that the line given is the hypotenuse (the longest side of a right-angled triangle) of a right-angled triangle and the other sides as a line from A going to the right, and a line from B going downwards, making the final vertexes for the triangle at coordinates: 0,-5 4,1 and 4,-5 (the vertex we made). now we find the lengths for the sides: 4 and 6 so we use these to plug them into pythagoras's equation:
4²+6²=c²
24+36=c²
√60=c
c=7.74....
But all we need is until the tenths so the answer is 7.7 (as the hundredths digit, 4, rounds down)

Step-by-step explanation:
the triangle is right angle.
at right angle it makes 90°. therefore;
(3d+1)°+(6d+8)°=90°
3d+1°+6d+8°=90°
9d+9°=90°.
9d=90°-9°
9d=81°
d=81/9
