A hiker walks at a speed of 3 2/5 km per hour. How many km will the hiker walk in 40 min?
Answer:
2 4/15 km
Step-by-step explanation:
We know from the above question that:
A hiker walks at a speed of 3 2/5 km per hour.
Step 1
Convert 40 minutes to hour
60 minutes = 1 hour
40 minutes = x
Cross Multiply
60x = 40
x = 40/60
x = 2/3hr
Step 2
How many km will the hiker walk in 40 min?
The above question can be calculated as:
1 hour = 3 2/5km
2/3 hour = x km
Cross Multiply
1 × x km = 2/3 × 3 2/5 km
x km = 2/3 × 17/5 km
x km = 34/15 km
x km = 2 4/15 km
Hence the hiker would walk 2 4/15 km in 4 minutes

If the simple interest on $7,000 for 3 years is $1890, then what is the interest rate?
Answer:
I = Prt
Interest = Principal x rate x time
Step-by-step explanation:
1890 = 7000(3)r
1890 = 21000r
r = 1890/21000
r = .09 or 9%

Tammy figured her math exam would be difficult unless she put in at
least 15 hours of study time to prepare. She studied 2½ hours on
Monday, 3 hours on Tuesday, 4¾ hours on Wednesday, and 4 ½
hours on Thursday. Did she study at least 15 hours? Explain.
Answer: She put 14 hours and 45 minutes into studying.
Step-by-step explanation: 2 1/2 hours plus 4 1/2 hours is 7 hours. Plus 3 is 10 hours. Plus 4 3/4 is 14 3/4 hours. 14 3/4 hours is = to 14 hours 45 minutes studying.

One year after you buy a tree, it is 10 feet tall. Each year after you buy the tree, it grows 2 feet. Write a function that represents the arithmetic sequence. How long does it take for the tree to reach its maximum height of 28 feet?
Answer:
y=2x+10
Step-by-step explanation:
y is the height x is the number of years
It takes 9 years for it to reach 28ft
The function c(x) = 18x -10 represents the cost in dollars. How many tickets can you buy?
Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.
So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 530 dollars.
The solution would still clear your concept though.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
c(x) = 18x -10
The slope-intercept form of the line equation
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so
c(x) = 18x - 10
comparing with the slope-intercept form of the line equation
rate of change = 18c(x) or y represents the cost'x' represents the number of ticketsAssuming the total cost i.e. c(x) = $530
In order to determine the value of x, set c(x) = 530
i.e.
530 = 18x -10
switch sides
18x - 10 = 530
add 10 to both sides
18x - 10 + 10 = 530 + 10
18x = 540
Divide 18 to both sides
18x/18 = 540/18
x = 30
Therefore, if you can buy x = 30 tickets if you pay 530 dollars.

Answer: Look below for the answers
Step-by-step explanation:
unit rates...
MOVIE TICKETS
$36/3=12
$12 for each ticket so
ICE CREAM CONES
$8.25/3=$2.75
$2.75 for each cone so
2 icecream cones cost $5.5
BANANAS
.99/3=.33
.33 for each banana so
.33*5=$1.65

Salt was mixed with pure water in a 1:3 proportion. What is the percentage of salt in the new solution?
Answer:
25%
Step-by-step explanation:
The proportion of salt in the mixture is 1:3; which means that for every portion of solution, salt makes up 1 part for every 3 parts of pure water.
Thus, salt makes up 1 part of every 1+3=4 portions of solution, or 25% ....................
Answer:
25 percent, because 1/4 is 0.25

An aquarium has a base in the shape of a trapezoid. The base is 80 cm long at the front, 50 cm long at the back, and 30 cm wide (from front to back). The height is 100 cm. What is the volume of the aquarium in litres?
Answer:
The volume of the aquarium is 195 litres.
Step-by-step explanation:
The volume ([tex]V[/tex]), measured in cubic centimetres, of the aquarium is equal to the area of the base multiplied by the height. That is:
[tex]V = \frac{1}{2}\cdot (L+l)\cdot w\cdot h[/tex] (1)
Where:
[tex]L[/tex] - Long leg length of the aquarium, measured in centimetres.
[tex]l[/tex] - Short leg length of the aquarium, measured in centimetres.
[tex]w[/tex] - Width of the aquarium, measured in centimetres.
[tex]h[/tex] - Height of the aquarium, measured in centimetres.
If we know that [tex]L = 80\,cm[/tex], [tex]l = 50\,cm[/tex], [tex]w = 30\,cm[/tex] and [tex]h = 100\,cm[/tex], then the volume of the aquarium is:
[tex]V = \frac{1}{2}\cdot (80\,cm+50\,cm)\cdot (30\,cm)\cdot (100\,cm)[/tex]
[tex]V = 195000\,cm^{3}[/tex]
If we know that a litre equals 195000 cubic centimetres, then the volume of the aquarium is:
[tex]V = 195000\,cm^{3}\times \frac{1\,L}{1000\,cm^{3}}[/tex]
[tex]V = 195\,L[/tex]
The volume of the aquarium is 195 litres.

A: B||F
B: B||D
C: C||E
D: C||D
E: D||F
F: E||F
Answer:
Options A, C and D
Step-by-step explanation:
Option A
Angle p = 180° - 89.5° = 90.5° [Linear pair of angles]
If b║f and line a is a transversal line,
m∠p = 90.5° [Alternate exterior angles]
True
Option B
If B║D and line a is a transversal,
m∠q = 89.5° [vertically opposite angles]
∠q + 89.5° = 89.5° + 89.5° = 179°
But angles q and angle with measure 89.5° are the consecutive interior angles and their sum should be 180°.
So the given statement is False.
Option C
c║e
Since, m∠r = 91.5° [Vertically opposite angle]
And m∠r + 89.5° = 180° [Consecutive interior angles]
True.
Option D
c║d
Since, ∠r and ∠q are consecutive interior angles,
m∠r + m∠q = 180°
91.5° + 89.5° = 180°
True
Option E.
d║f
m∠s = 90.5°[Vertically opposite angles]
Since, ∠s and angle with measure 89.5° are the alternate interior angles,
So measure of angle s should be 89.5°.
Therefore, d║f is False.
Option F.
If e║f, angles with measures 89.5° and 90.5° should be equal.
But measures of both are different.
Therefore, e║f is False.
Options A, C and D are the correct options.
