Answer:
The answer will be 7L/100km.
Step-by-step explanation:
The fuel consumption rate is already given for the first 100 km. So, the next 500 km will be 100km to 600km. You have to find the slope of the line during this travel. If you observe, the fuel lowers from 40 litres to 5 litres in this 500km journey. That means, 35 litres were used for 500km. Divide both with 5. That gives 7litres per 100km.
Hey there! :)
Answer:
x = 7L/100km.
Step-by-step explanation:
Solve this problem by using the slope formula:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Use the points (100, 40) and (600, 5) and plug these into the formula:
[tex]m = \frac{5-40}{600-100}[/tex]
Simplify:
[tex]m=\frac{-35}{500}[/tex]
Since this is describing the rate of consumption, we can simply write the slope as:
[tex]m = \frac{35}{500}[/tex]
The question is asking for the rate of consumption over 100 km, therefore:
[tex]\frac{35}{500} = \frac{x}{100}[/tex]
Cross multiply:
3500 = 500x
Divide both sides by 500:
3500/500 = 500x/500
x = 7L/100km.

Answer:
c=8
Step-by-step explanation:
-3(2c+5)=33
-6c-15=33
-6c=33+15
-6c=48
c=48/6
c=8
Answer:
if you are solving for C it will be -8.
Step-by-step explanation:
Start by dividing both sides of the equation by -3.
2c + 5= -11
Now Subtract 5 from both sides
2c = -11 - 5 (combime like terms) so 2c = -16
Now divide both sides by 2
You will get C= -8

In the diagram, the measure of angle 2 is 126°, the measure of angle 4 is (7x)°, and the measure of angle 5 is (4x + 4)°. A transversal intersects 2 lines to form 8 angles. Clockwise from the top left, the angles are 1, 2, 3, 4; 5, 6, 7, 8. What is the measure of angle 7, to the nearest degree? 35° 54° 76° 104°
Answer:
The correct option is C
C) 76°
Step-by-step explanation:
The question is incomplete because the figure is not given. I have attached the figure of the same question below. Consult it for better understanding.
We can see in the figure that <2 and <4 are opposite angles, therefore these are equal.
<2 = <4
126 = 7x
x = 18
Similarly we can also see that <5 and <7 are also opposite angles, therefore they are equal too.
<7 = <5
<7 = 4x+4
Substitute x=18
<7 = 4(18) + 4
<7 = 76°
Answer:
option c

Answer:
Total combination = 180,180
Step-by-step explanation:
It is a combination based problem.
So,
Total people = 13
Group = 3,6,2,2
So,
For 6 people
13C6= 1,716
For 3 people
7C3 = 35
For 2 group of 2 people
(4C2)/2 = 3
Total combination = 1,716 × 35 × 3
Total combination = 180,180
WILL GIVE BRAINLIEST TO THE BEST CORRECT ANSWER!!!!!!! The people of Bridgetown wanted to build a bridge across a nearby river. Since they were poor swimmers, their master Trigonomos agreed to measure the width of the river without actually crossing it. Trigonomos spotted a tree across the river and marked the spot directly across from it. Then he walked to another point 10 meters down the river and found that the angle between his side of the river and the line connecting him to the tree was 40º. What is the width of the river in meters? Round your final answer to the nearest hundredth.
Answer:
The width of the river is about 8.39 m.
Step-by-step explanation:
Tan = Opposite/Adjacent
The width of the river is the side of a right triangle opposite the angle of 40°. The 10 m distance is the length of the side adjacent to the measured angle. So, we have ...
tan(40°) = width/(10 m)
Multiplying by 10 m, we get ...
width = (10 m)tan(40°) ≈ 8.39 m
The width of the river is about 8.39 m.

I NEED HELP ASAP!!!!This table shows how many male and female students attended two different movies. What is the probability that a randomly chosen person from this group an action movie?
Answer:
0.43 is the answer
Step-by-step explanation:
you need to take the total of action movie and divide it by the grand total.
204/478 ≈ 0.43
The probability that a randomly chosen person from this group an action movie is 0.43.
What is probability?Probability refers to the idea that an event may or may not happen. The scenario described here is a mutually exclusive event. We must recall that in cases of a mutually exclusive event, we add probabilities.
Hence;
Probability of a male watching an action movie = 105/479
Probability of a female watching an action movie = 99/479
probability that a randomly chosen person from this group an action movie = 105/479 + 99/479 = 0.43

y = COS X?
A. y = csc x
B. y = sin x
C. y = cos(x+pi/2)
D. y = sec x
Answer:
B. y = sin x
Step-by-step explanation:
Write the first four terms in the following sequences. A(n+1)=12 A(n) for n≥1 and A(1)=4 . i need help how can i get the first 4 terms?
The 12 out front of A(n) means we multiply 12 and A(n) to get the next term A(n+1). We do this as many times as we want to generate as many terms as we want.
We start with the first term 4
The second term is 4*12 = 48
The third term is 48*12 = 576
The fourth term is 576*12 = 6912
The first four terms are 4, 48, 576, and 6912.A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 5 milliliters of compound B. If a chemist wants to make 576 milliliters of the drug, how many milliliters of compound A are needed?
Answer:
216 milliliters of compound A are needed.
Step-by-step explanation:
There are two unknowns for the constituents of the final 576 milliliters of the drug:
amount of compound A (which we name A), and
amount of compound B (which we name B)
So we know two things that can be written in equation form;
1) there are 3 milliliters of A every 5 milliliters of B:
[tex]\frac{B}{A} =\frac{5}{3} \\B=\frac{5}{3}\,A[/tex]
2) the chemist mixes 576 milliliters of the drug:
[tex]A\,+\,B\,= 576[/tex]
So we now replace B with its expression in terms of A (from our first equation) in the second equation, and solve for A:
[tex]A\,+\,B\,= 576\\A\,+\,\frac{5}{3} A=576\\\frac{8}{3} \,A=576\\A=\frac{576\,*\,3}{8} \\A=216[/tex]
So 216 milliliters of compound A are needed.
An observer (O) spots a plane (P) taking off from a local airport and flying at a 33° angle horizontal to her line of sight and located directly above a tower (T). The observer also notices a bird (B) circling directly above her. If the distance from the plane(P) to the tower (T) is 7,000 feet, how far is the bird (B) from the plane (P)? Round to the nearest whole number.
Answer:
the distance of the Bird (B) from the plane (P) is = 10779 ft
Step-by-step explanation:
From the given information:
a diagrammatic representation is attached below for better understanding and solution to the question.
From the diagram;
Let the Bird (B) be represent as A
The plane (P) be represented by B
The observer be represented by O
and the tower T be represented by C
we will see that:
[tex]\overline {AB} \ \| \ \overline {OC}[/tex]
Also;
[tex]\angle ABO = \angle BOC = 33^0[/tex]
AO = BC = 7000
Let consider the trigonometry of triangle BAO
tan θ = opposite/adjacent
tan 33° = 7000/x
0.6494 = 7000/x
x = 7000/0.6494
x = 10779.18
x = 10779 ft ( to the nearest whole number)
Thus; the distance of the Bird (B) from the plane (P) is = 10779 ft
Answer: 10,779 feet

[tex]\frac{7r}{7}=7\left(-8\right)[/tex]
7*-8=-56
7 and 7 is eliminated
so x=-56
Answer:
r= -56
Step-by-step explanation:
The equation given is:
[tex]\frac{r}{7}= -8[/tex]
We want to solve for r. In order to do this, we must get r by itself.
Currently, r is being divided by 7. We want to perform the inverse, which is multiplication. Therefore, we should multiply both sides of the equation by 7.
[tex]7*\frac{r}{7}= -8 * 7[/tex]
[tex]r=-8*7[/tex]
[tex]r= -56[/tex]
Let's check our solution. Substitute -56 back in for r and solve.
[tex]\frac{r}{7}= -8[/tex]
[tex]\frac{-56}{7}= -8[/tex]
[tex]-8=-8[/tex]
Both sides of the equation are the same, so we know our answer is correct.
