A car uses a litre of petrol to travel 4km. How many litres will it use to travel 32 kilometres.
Given that,
A car uses a litre of petrol to travel 4 km.
To find,
How many litres will it use to travel 32 kilometres.
Solution,
We have,
1 litre = 4 km
or
1 km = (1/4) litre
Let it will use x litres to travel 32 km.
32 km = (32/4) litres
= 8 litres
Hence, 8 litres it will use to travel 32 km.

The respective unit rates are 6,9,7
What is the unit rate?Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.
Given here: Cam 1 clicks 30 pics in 5 secs
∴ Unit rate of Cam 1= 30/5
=6 pics/sec
Similarly we can find
Unit rate of Cam 2=9 pics/sec
Unit rate of Cam 3= 7 pics/sec
Hence, The respective unit rates are 6,9,7

Which of the following could be the graph of the equation y= -2x + 5? How do you know??(plz answer!!)
Answer:
The answer is c.
Step-by-step explanation:
This is because the slope is a negative, and since letter a, has a positive slope, it's out of the picture. Just by the looks of b, you can tell that the why intercept isn't 5. It looks like its y-intercept is 0. Letter d, also doesn't have a positive y-intercept so it's also out of the picture. Which leaves letter c. It has a positive slope and it looks like it has 5 as a y-intercept.

Convert to degrees −31π/36
Answer:
−31π/36 = -15.5°
Step-by-step explanation:
We need to convert −31π/36 to degrees.
The conversion from radian to degrees is calculated as follows :
[tex]\text{Degrees}=\dfrac{180}{\pi }\times \text{radian}\\\\=\dfrac{180}{\pi}\times \dfrac{-31\pi }{360}\\\\=-15.5^{\circ}[/tex]
So, −31π/36 is equal to -15.5 degrees.

On a windy morning, a hot air balloon starts rising and flying away from the top of a hill. The altitude, h, in feet, of the balloon x hours after starting its ascent from the hill, can be modeled by the function:
Part A: What is the y-intercept for this function? What does the y-intercept represent in the given situation? Use your equation to explain how you found your answer.
h(x)=-16x2+64x+80
Answer:
The y-intercept is y = 80feet. The initial height of the balloon is 80feet.
Step-by-step explanation:
[tex]h(x)=-16x^2+64x+80[/tex]
The y-intercept of the function happens when the x-value = 0. So let's plugin x=0 into the function:
[tex]h(x)=-16x^2+64x+80\\h(x)=-16(0)^2+64(0)+80\\h(x)=80[/tex]
The y-intercept is y = 80feet
x represents the number of hours after starting its ascent from the hill, so x = 0hr means when the balloon is just starting to ascent. At the start of the ascent, the balloon has an altitude of 80feet. The initial height of the balloon is 80feet.
The y-intercept is y = 80feet.
The initial height of the balloon is 80feet.
Calculation of the y-intercept and initial height:Since the equation is [tex]h(x)=-16x^2+64x+80[/tex]
So here x = 0
So
[tex]h(x)=-16(0)^2+64(0)+80[/tex]
= 80
Here, The y-intercept is y = 80feet
Also,
x means the number of hours after starting its ascent from the hill

Given that if x = 7 and y = 4, the value of x + 2y = 15
Given the following:
x = 7
y = 4
Required:
Find the value of x + 2y.
Therefore, substitute x = 7 and y = 4 into the algebraic expression, x + 2y.
Thus, plug in the values into the expression:(7) + 2(4) = 7 + 8
x + 2y = 15
Therefore, given that if x = 7 and y = 4, the value of x + 2y = 15

The ratio of wins to losses for the spartan football team is 3:5. If this trend continues and they play a total of 16 games, how many can they expect to win?
Answer:
10 games
Step-by-step explanation:
The team can expect to win 6 matches.
What is ratio?A ratio is a way to show a relationship or compare two numbers of the same kind. We use ratios to compare things of the same type.
Given that, The ratio of wins to losses for the spartan football team is 3:5. and this trend continues, they play a total of 16 games,
Let they won 3k games and loose 5k games.
Then,
3k+5k = 16
8k = 16
k = 2
Therefore, they lose 5·2 = 10 matches and won 3·2 = 6 matches.
Hence, the team can expect to win 6 matches.

Find how many had taken one course only by using Venn diagram.
Answer:

Step-by-step explanation:
The number of students taken only one course is 106
What is Venn diagram?A Venn diagram exists as an illustration that utilizes circles to illustrate the relationships among things or finite groups of things. Circles that overlap include a commonality while circles that do not overlap do not share those traits. Venn diagrams permit visually illustrating the similarities and contrasts between two concepts.
Let M =sets of students who had taken mathematics
C= sets of students who had taken chemistry
P= represent sets of students who had taken physics
From the given information, we have
n(M) = 64 , n(C) = 94, n(P) = 58,
n(MnP) = 28, n(MnC) = 26, n(CnP) = 22
n(MnCnP) = 14
No. of students who had taken only Math :
= n(M) - [n(MnP) + n(MnC) - n(MnCnP)]
= 64 - [28+26-14]
= 64 - 40
= 24
No. of students who had taken only Chemistry
= n(C) - [n(MnC) + n(CnP) - n(MnCnP)]
= 94 - [26+22-14]
= 94 - 34
= 60
No. of students who had taken only Physics
= n(P) - [n(MnP) + n(CnP) - n(MnCnP)]
= 58 - [28+22-14]
= 58 - 36
= 22
Total no. of students who had taken only one course
= 24 + 60 + 22
= 106
