Write the word sentence as an inequality. Then solve the inequality. Eight times a number $n$ is less than 72
Answer:
8n < 72
n < 9
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
8 times n = 8n
8n is less than 72, this can be represented by the equation : 8n < 72
to determine the value of n, divide both sides of the equation by 8
n < 9
Which equation represents a line that passes through (5,1) and has a slope of 1/2?
Answer:
y = 1/2x - 3/2
Step-by-step explanation:
y = 1/2x + b
1 = 1/2(5) + b
1 = 5/2 + b
-3/2 = b
Answer:
y=1/2x-3/2
Step-by-step explanation:
y-y1=m(x-x1)
y-1=1/2(x-5)
y-1=1/2x-5/2
y=1/2x-5/2+1
y=1/2x-5/2+2/2
y=1/2x-3/2

Find numbers a and b, or k, so that f is continuous at every point.
Answer:
[tex] \boxed{k = 7} [/tex]
Step-by-step explanation:
When interpreting this piecewise function, to determine whether or not the function is continuous, the limit to the left must be the same as the limit to the right.
Therefore to find an a value where the function is continuous at every point, we must determine where the limit is for the function.
In this case, the function is continuous at x = 7.
lim x→7 [x²] = lim x→7 [kx].
(7)² = k(7)
49 = 7k
÷7 ÷7
7 = k
k = 7.

Answer:
x =10
Step-by-step explanation:
3x + 10 = 6x -20
3x - 6x + 10 = -20
-3x + 10 = -20
-3x = -20 -10
-3x = -30
x = -30/-3
x = 10
Check:
3(10) + 10 = 6(10) - 20
30 + 10 = 60 - 20

There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?
(hegarty maths))
Answer:
The probability of getting 2 blues is 25/121.
Step-by-step explanation:
There are 6 + 5 marbles in total, 11 marbles.
The chances of picking a blue marble is 5/11.
Since you replace the marble you drew, the chances each draw remain 5/11
You cannot draw two red marbles without drawing a red marble on your first draw, so the odds of you making a second draw are 5/11.
5/11 * 5/11 = 25/121
The probability of getting 2 blues is 25/121.

Answer:
140.3 ft³
Step-by-step explanation:
Volume of cylinder = πr²h
= π x 1.5² x 4
= 28.3 ft³
P.S. The diameter in the picture is 3ft. FIrst, change it to radius. 3/2= 1.5 ft
Volume of cuboid = lwh
= 7 x 4 x 4
= 112 ft³
Total volume = 112 + 28.3 = 140.3

a survey of 100 high school students provided this frequency table on how students get to school: what is the probability that a randomly selected student either takes the bus or walks
Answer:
3/5
Step-by-step explanation:
;)
The probability that a randomly selected student either takes the bus or walks is 3/5.
What is the probability?
The probability formula defines the likelihood of the happening of an event. It is the ratio of favorable outcomes to the total favorable outcomes.
A survey of 100 high school students provided this frequency table on how students get to school:
The probability that a student selected is a senior student or one that drives to school.
From the table, the number of senior students is 25 + 20 + 5 = 50
So the probability of selecting a senior student is 50/100 = 1/2
Now the probability of selecting a student that drives to school.
The number of students that drive to school is 3 + 2 +5 = 10
So the probability of a student who drives to school is 10/100 = 1/10.
The probability that a randomly selected student either takes the bus or walks is;
[tex]=\dfrac{1}{2}+\dfrac{1}{10}\\\\= \dfrac{1 \times 5+1\times 1}{10}\\\\= \dfrac{1+5}{10}\\\\= \dfrac{6}{10}\\\\=\dfrac{3}{5}[/tex]
Hence. the probability that a randomly selected student either takes the bus or walks is 3/5.

an=an−1+5.6, where a1=−2.7
an=an−1−5.6, where a1=−2.7
Answer:
[tex]a_{n} =a_{n-1} -5.6[/tex] where [tex]a_{1} =-2.7[/tex]
Step-by-step explanation:
This is an arithmetic sequence with the first term is [tex]a_{1}[/tex] = -2.7 and has a common difference of [tex]d=-5.6[/tex].
Arithmetic Sequence: [tex]a_{n} =a_{n-1} +d[/tex]
[tex]a_{n}[/tex] is the nth term and [tex]d[/tex] is the common difference.
The common difference: -2.7, -8.3, -13.9...
Subtract: -2.7- (-8.3) = -5.6, -13.9 - (-8.3) = -5.6
Common difference: [tex]d = -5.6[/tex]
Recursive rule: [tex]a_{n} = a_{n-1} -5.6[/tex]

What’s the least number of faces a polyhedron can have? And why?
Answer:
The minimum number of faces a polyhedron can have is 4 faces.
Step-by-step explanation:
We know that a polyhedron is a shape surrounded by polygons. We also know that we need at least 3 sides to make a polygon. So, at the minimum a polyhedron can be made by using only triangular faces but in order to make a closed figure we need at least four triangular faces (which is a tetrahedron).
