(282-14*3*6)/(6) -(21-18)
Answer:
2
Step-by-step explanation:
( 282 - 14 ⋅ 3 ⋅ 6 ) / ( 6 ) - ( 21 - 18 )
= 30/( 6 ) - ( 21 - 18 )
= 30/( 6 ) - 3
[tex]=\frac{30}{6} -3[/tex]
= 2
Answer:
[tex]27[/tex]
Step-by-step explanation:
1) Simplify 14 × 3 to 42.
[tex]282 - 42 \times 6 - (21 - 18)[/tex]
2) Simplify 21 - 18 to 3.

A diver is on a diving board 12 meters above the water. He dives vertically from the board with initial velocity of 4.9 meter/sec. how high will the diver get above the water?
Answer:
13.225 m
Step-by-step explanation:
Given that :
Initial Velocity, u = 4.9m/s
Acceleration due to gravity, a = - 9.8 m/s² (downward)
Distance, S = - 12
According to the motion equation :
S = ut + 0.5at²
S = 4.9t + 0.5(-9.8)t²
S = 4.9t - 4.9t² - - - (1)
At the highest point, v = 0
v² = u + at
0 = 4.9 + - 9.8t
-9.8t = - 4.9
t = 4.9/9.8
t = 0.5s
Put t = 0.5 in (1) above
S = 4.9(0.5) - 4.9(0.5)²
S = 2.45 - 1.225
S = 1.225 m
Total height :
(12 + 1.225) m = 13.225 m

Prism A is a triangular prism. The triangular base has a base of 7 meters and height of 9 meters. The prism has a height of 4 meters. Prism B is a rectangular prism with length of 8 meters, width of 2 meters, and height of 8 meters.
Which prism has the least volume?
Prism ________
Answer:
A
Step-by-step explanation:
Prism A Volume
The Column of Prism A = Base (Area) * Height.
I think you have to assume that the triangle is a right triangle.
Area of the triangle = 1/2 * 9 * 7
Area of the triangle = 1/2 63
Area of the triangle = 31.5
Volume of the Prism = area of the triangle * thickness
Volume of the prism = 31.5 * 4
Volume of the prism = 126 m^3
Prism B = L * w * h
Prism B = 8 * 8 * 2
Prism B = 128
Prism A has the least volume by just a little.
Answer:
Prism A has the least volume

Find the equation of the linear function represented by the table below in slope-
intercept form.
х
у

8

12

20
Answer:
y = 4x+4
Step-by-step explanation:
Using the coordinate point (1, 8) and (2, 12) from the table
Slope m = 12-8/2-1
m = 4/1
m = 4
Get the intercept
Substitute m = 4 and (1, 8) into y = mx+c
8 = 4(1) + c
8 - 4 = c
c = 4
Get the required equation
y = 4x + 4
Hence the required linear equation is y = 4x+4

Answer:
B. {x| -3 < x ≤ 2}
Step-by-step explanation:
The unshaded "O" on "-3" implies that -3 is not included. Which means -3 < x or x > -3.
The shaded "O" on "2" implies that 2 is included, therefore, x is either equal to 2 or less than 2 (x ≤ 2) since the line is towards our left side. This, we would have:
{x| -3 < x ≤ 2}

The yearbook club had a meeting. The meeting had 18 people, which is one-third of the club. How many people are in the club?
Answer:
54
Step-by-step explanation:
Number of people in the meeting= 18
Out of this number 1/3 are from the club
Therefore the total number of club members can be calculated as follows
= 1/3 × x= 18
x = 18 × 3
= 54
Hence the number of people in the club is 54
At 186282 miles per second, how far does light travel in a year? Give your answer in miles, but use scientific notation, which expresses a number like 93400000 as 9.34 × 107 (which might appear on your calculator as 9.34 E7 instead). A year is approximately 365.25 days. pleaasseeeeee heeelelpepepel,
Answer:
Use dimensional analysis to answer each of the following questions. To find the distance light travels in a year for part a, convert sec to yr by using unit ratios with min, hr, and days in their denominators. Thus, a light year is approximately 5,874,589,152,000 mi
The number of miles that the light covers in a light year will be 5.89 × 10¹² miles.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
At 186282 miles per second.
We know that in one light year, the number of seconds will be 31.536 × 10⁶.
Then the distance is given as,
186282 = d / (31.536 × 10⁶)
d = 31.536 × 10⁶ × 186282
d = 5.89 × 10¹² miles
The number of miles that the light covers in a light year will be 5.89 × 10¹² miles.
More about the speed link is given below.

A gambler claims that horses in a horse race that start closer to the rail have an advantage over horses that start further from the rail because the horses closer to the rail have a shorter distance to travel to win the race. In a sample of 120 races, the following data show the number of winners from each starting position. If the starting position is not a factor then each starting position should have produced 20 winners.
Starting position: 1 2 3 4 5 6
# of Winners: 25 22 18 19 21 15
Test the hypothesis at the 5% level of significance to see if starting position is a factor.
Answer:
Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS
there is no significant evidence that starting position is a factor in horse races
Step-by-step explanation:
Given the data in the question;
Starting position: 1 2 3 4 5 6
# of Winners: 25 22 18 19 21 15
Mean x" (E) = (25+22+18+19+21+15)/6 = 120/6 = 20
Observed/Expected value table;
O E ((O-E)²) / E
25 20 1.25
22 20 0.2
18 20 0.2
19 20 0.05
21 20 0.05
15 20 1.25
∑ 3
so using chi square = ∑(((O-E)²) / E) = 3
DF = n-1 = 6-1 = 5
then, the critical chi square value is;
significance level = 0.05
chi square( critical ) = 11.07049769
from table;
p - value = 0.699986
Hence, the p-value ( 0.699986) > 0.05, FAIL TO REJECT THE NULL HYPOTHESIS
there is no significant evidence that starting position is a factor in horse races

If money is invested for a short period of time, simple interest is paid using the following formula.
I = Prt
P is the money invested, or principal amount, r is the simple interest rate, and t is the time, in years, the money is invested.
Given P = $2,000, t = 2 years, and I = $280, what is the simple interest rate?
A. 7%
B. 0.7%
C. 8%
D. 0.07%
Answer:
A. 7%
Step-by-step explanation:
Given the following data;
Principal, P = $2,000
Time, T = 2 years
Simple Interest, I = $280
To find the simple interest rate, R?
Mathematically, simple interest is calculated using this formula;
[tex] S.I = \frac {PRT}{100} [/tex]
Where;
S.I is simple interest. P is the principal. R is the interest rate. T is the time.Substituting into the equation, we have;
[tex] 280 = \frac {2000*R*2}{100} [/tex]
Cross-multiplying, we have;
[tex] 280 * 100 = 4000*R[/tex]
[tex] 28000 = 4000R [/tex]
[tex] R = \frac {28000}{4000} [/tex]
Simple interest rate, R = 7%
