Hope it helps :)
Please mark my answer as the brainliest
Answer:
I'm not 100% sure but I think it's 9.72x10^4
Step-by-step explanation:
Basically just move the decimal place to the left until your front number is in the ones place. Then, however many places you move the decimal point over is what power you'll raise 10 to. I haven't done it in a while but I think that's how you do it
A billiard ball is struck by a cue. It travels 100 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the ball approaches the rail and the path after it strikes the rail is 45 degrees. How far is the corner pocket from where the cue initially struck the ball?
Answer:
76.53 cm
Step-by-step explanation:
From the question, the triangle formed has 2 sides and an included angle ;
Angle, θ = C = 45°
We use cosine rule :
Taking the side to find as c
a = 100 ; b = 100
From cosine rule :
c = sqrt(a² + b² - 2abCosC)
c = sqrt(100² + 100² - 2(100*100)Cos45
c = sqrt(10000 + 10000 - 20000 * 0.7071067)
c = sqrt(20000 - 14142.135)
c = sqrt(5857.865)
c = 76.536690
c = 76.53 cm

what is the measure of angle DEF.
Answer:
DEF = 31.8
Step-by-step explanation:
90 - 58.2 = 31.8
Answer:
Angle DEF = 31.8°
Step-by-step explanation:
The complete angle is a right angle, or 90° angle. To find DEF, you can just do 90° - 58.2° = 31.8°
Solve the compound inequality
3t-8/5 and 4-t<-7
Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8

IF m power n is equal to 32 wher m and n are natural numbers then find the value of n power m
Answer:
[tex]n^m = 5^2[/tex]
Step-by-step explanation:
Given
[tex]m^n = 32[/tex]
Required
Find [tex]n^m[/tex]
[tex]m^n = 32[/tex]
Express 32 as an exponent
[tex]m^n = 2^5[/tex]
By comparison:
[tex]m = 2[/tex]
[tex]n = 5[/tex]
So:
[tex]n^m = 5^2[/tex]

The mean of 6, 8, x + 2, 10, 2x - 1, and 2 is 9. Find the value of x and also the value of the observation in the data.
Answer:
x = 9
Number of observations = 6
Sum of observations = 54
Step-by-step explanation:
Number of observations, n = 6
Mean = ΣX / n
(6 + 8 + x + 2 + 10 + 2x - 1 + 2) / 6 = 9
(27 + 3x) / 6 = 9
27 + 3x = 6 * 9
27 + 3x = 54
3x = 54 - 27
3x = 27
x = 27 / 3
x = 9
what is 28/10 as a proper fraction
Answer:
Step-by-step explanation:
28/10 as a proper fraction.
28/10 is an improper fraction so you have to turn it into a proper fraction.
To do this divide the numerator (top figure) by 10 (the denominator) which equals 2.8 so to put it as a proper fraction you look at the whole number in 2.8 which is the 2 and keep the number after the decimal point as a fraction over the 10.
The answer would be 2 8/10

15x^2 + 41x + 28
STEP BY STEP ANSWER PLSSS
Answer:
(3x+4)(5x+7)
Step-by-step explanation:
15x^2 +41x+28
Factor the expression by grouping. First, the expression needs to be rewritten as 15x^2 +ax+bx+28. To find a and b, set up a system to be solved.
a+b=41
ab=15×28=420
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 420.
1,420
2,210
3,140
4,105
5,84
6,70
7,60
10,42
12,35
14,30
15,28
20,21
Calculate the sum for each pair.
1+420=421
2+210=212
3+140=143
4+105=109
5+84=89
6+70=76
7+60=67
10+42=52
12+35=47
14+30=44
15+28=43
20+21=41
The solution is the pair that gives sum 41.
a=20
b=21
Rewrite 15x^2 +41x+28 as (15x^2 +20x)+(21x+28).

Sac had a rope that was 15 feet long. He cut it into three pieces. The first piece was 3.57 feet longer than the second piece. The third piece was 2.97 feet longer than the second piece. How long was the third piece of rope?
Answer:
5.79 feet
Step-by-step explanation:
Let us represent
First piece = x
Second piece = y
Third piece = z
Sac had a rope that was 15 feet long.
x + y + z = 15
He cut it into three pieces.
The first piece was 3.57 feet longer than the second piece.
x = 3.57 + y
The third piece was 2.97 feet longer than the second piece.
z = 2.97 + y
How long was the third piece of rope?
x + y + z = 15
3.57 + y + y + 2.97 + y = 15
3y + 6.54 = 15
3y = 15 - 6.54
3y = 8.46
y = 8.46/3
y = 2.82 feet
Therefore, the length of the third piece z = 2.97 + y
z = 2.82 + 2.97
z = 5.79 feet

Step-by-step explanation:
1.
6 * 6 = 36
6 * 6 / 2 = 18
4(18) = 72 (4 triangles)
SA = 36 + 72 = 108 in^2
2.
11 * 4.5 = 49.5
2(49.5) = 99 (2 flaps)
7 * 4.5 = 31.5
2(31.5) = 63 (2 flaps)
11 * 7 = 77
2(77) = 154 (2 flaps)
SA = 99 + 63 + 154 = 316 in^2
3.
25 * 25 = 625
6(625) = 3750 (6 squares)
SA = 3750 ft^2
4.
40 * 60 = 2400
3(2400) = 7200 (3 flaps)
25 * 40 /2 = 500
2(500) = 1000 (2 flaps)
SA = 7200 + 1000 = 8200 cm^2
5.
15 * 9 = 135
3(135) = 405 (3 flaps)
8 * 9 /2 = 36
2(36) = 72 (2 flaps)
SA = 405 + 72 = 477 in^2
6.
9 * 12 = 108
10 * 9 /2 = 45
2(45) = 90 (2 flaps)
12 * 10 /2 = 60
2(60) = 120 (2 flaps)
SA = 108 + 90 + 120 = 318 mm^2

Mike is mixing paint for his walls. He mixes 1/6 gallon blue paint and 5/9 gallon green paint in a large container. What fraction represents the total amount of paint Mike mixes? The total amount of paint Mike mixes is gallon(s).
Answer:
13/18
Step-by-step explanation:
Mike is mixing paints for his walls
He mixes 1/6 gallons of blue paint
He also mixes 5/9 gallons of green paint
Therefore the total amount of paint mixed can be calculated as follows
1/6 + 5/9
= 39/54
= 13/18

On Sunday morning, 4 1/2 crates of grapes are delivered to thee grocery store. 2/5 of the grapes in each crates are green grapes. How many crates would it take to deliver only the green grapes?
Answer: 1 4/5 crates
Step-by-step explanation:
From the question, we are informed that 4 1/2 crates of grapes are delivered to a grocery store and that 2/5 of the grapes in each crates are green grapes.
The number of crates that it would take to deliver only the green grapes would be:
= 2/5 × 4 1/2
= 2/5 × 9/2
= 9/5
= 1 4/5 crates

convert (-5√3,0) into polar form in radians in terms of π over the interval 0≤theta<2π
Answer:
z = 5√3(cos 0 + isin0)
Step-by-step explanation:
Convert (-5√3,0) into polar form in radians in terms of π over the interval 0≤theta<2π
The rectangular form is expressed as z = -5√3 + 0i
z = √(-5√3)² + 0²
z = √(25(3))
z = √75
z = 5√3
Get the argument
theta = tan^-1 0/-5√3
theta = tan^-10
theta = 0 degrees
Hence the polar form is expressed as z = r(cos theta + i sintheta)
z = 5√3(cos 0 + isin0)
