A student mixed 3/5 liter of citric acid solution. He used 1/6 of the citric acid solution for the experiment. How much of the citric acid solution did he use? Be sure the answer is in simplest form
Answer:
1 / 10 L
Step-by-step explanation:
Litres of citric acid solution = 3/5
Fraction of solution used = 1/6
1/6 of 3/5
1/6 * 3/5
= (1 * 3 / (6 * 5)
= 3 / 30
= 1/ 10

The diagram shows a right-angled triangle and a parallelogram.
The area of the parallelogram is 5 times the area of the triangle.
The perpendicular height of the parallelogram is
h
cm.
Find the value of
h
(3 marks)
h=
cm
Answer:
h = 12
Step-by-step explanation:
area of triangle = 16x9x0.5= 72 cm^2
area of parallelogram = 72 x 5 = 360 cm^2
area of parallelogram = base x height(h)
360 = 30h
divide both sides by 30
h = 12

Known thatf(x) = 3x + 2

Questionf(5) = ..?
════════════════════
Way to do#since the x inside (x) change into (5), then just change the x with (5)
f(x) = 3x + 2
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17

The length of a rectangle is 16 units more than its width. The area of the rectangle can be expressed as
x^4 – 64.
Which expression represents the width of the rectangle?
The width of the rectangle represented by the expression (x⁴ – 64)/x.
What is rectangular shape?A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.
Given:
The length of a rectangle is 16 units more than its width.
Let the length is x units.
Then width = (x + 16) units.
The area of the rectangle can be expressed as
x⁴ – 64 = length x width
x⁴ – 64 = x (x + 16)
x + 16 =(x⁴ – 64)/x
Therefore, the width expression is (x⁴ – 64)/x.

A school with a population of 2,500 students experiences a flu outbreak. It is found that the number of healthy students at the school is decreasing at a rate of 15% each day. Which function can be used to find the number of healthy students at the school d days after the outbreak begins?
Answer:
y=2500(0.85)^d
Step-by-step explanation:
Seeing as there are no option choices, I shall digress.
Because of a decrease of 15% each day, it means exponential decay. Using the formula y=a(1-r)^x, we have y=2500(1-0.15)^d -> y=2500(0.85)^d
Your function would thus be y=2500(0.85)^d
Answer:
The function that can be used is x = (2500 × 0.15)(number of days, or d)
Step-by-step explanation:
First we can create an equation to find this easier. We can say that x, or the number of infected students, is equal to (2500 × 0.15), since percentages are easily changed into decimals, and multiply that by the number of days or d.
Kalani has run 4 1/5 miles in 2/3 an hour. If he continues to run at this rate, how many miles will he run in one hour?
Answer:
Kalani will run 6.3 miles OR 6 3/10 miles.
Step-by-step explanation:
So first step that I would do is make it easier to understand by converting the fraction to a whole number. 2/3 hour= 40 minutes.
So Kalani runs 4 1/5 miles in 40 minutes.
Then, we convert 4 1/5 to 4.2. Next, I would divide 4.2 by 2 to get how long he ran in 20 minutes. 4.2/2=2.1.
The final step is to add 2.1 and 4.2 and we get 6.3.
Extra step:
But if we need to turn it back into a fraction, it would be 6 3/10

E = mc2.
m is the mass of the object.
c is the speed of light.
Which equation finds m, given E and c?
#Equation of m?
Equationm = E/c²
Way to find itE = mc²
E : c² = m
E/c² = m
So, the formula of m is E/c²

Step-by-step explanation:
You buy a day pass to use the subway for $5. After buying the pass, you pay $2 per ride. Write an equation to describe how much money, y, you pay to ride x number of rides.
Hi there!
So here says that when I buy a day pass using the subway I pay $5 and $2 per ride.
This means that it’ll be $7 per ride.
y=7
x=1
So for every 1 ride on the subway, I have to spend $7.

Answer:
The answer is 16.
Step-by-step explanation:
First you need to substitute the letters with the number.

Answer:
About 3 times faster
Step-by-step explanation:
Cheetah's speed = 110 km / hr
World 100m sprint record :
Speed of sprinter :
Distance / time
100 m / 9.58s
= 10.438413 m/s
Convert Cheetah's speed to m/s
110 km/hr = (110 * 1000)m / (60 * 60 s)
= 110000 m / 3600 s
= 30.55555 m/s
Number of times cheetah is faster than sprinter :
30.55555 m/s ÷ 10.438413 m/s
= 2.927 times
