Step-by-step explanation:
To find the constant of proportionality in the set of data apply the formula for slope where;
m= Δy/Δx
Taking values such as {3,2} and {6,4} then
m= 4-2 / 6-3
m= 2/3

(A journey by bus takes 45 minutes at 60 km per hour. How fast must a car go to do the same
journey in 25 minutes? plzz answerr!!!
Answer:
The car must drive at 108 km/h to cover the same journey.
Step-by-step explanation:
Given that:
Time taken by bus journey = 45 minutes = [tex]\frac{45}{60} = 0.75\ hour[/tex]
Speed of bus = 60 km/h
Distance of the journey = Speed * Time
Distance of the journey = 60 * 0.75 = 45 km
The car needs to cover 45 km in 25 minutes.
25 minutes = [tex]\frac{25}{60}\ hour[/tex]
Distance = Speed * Time
45 = [tex]\frac{25}{60}*Speed[/tex]
Speed = [tex]45*\frac{60}{25}[/tex]
Speed = 108 km/h
Hence,
The car must drive at 108 km/h to cover the same journey.

5 x 6 = 30
6 x 6 = 36
8 x 6 = 48
Answer:
8
Step-by-step explanation:
The answer is 8 because the scale factor is 6 so if you divide the side that is corresponding to x (in this case 48) you would divide it by 6 because 6 is the scale factor. Hopefully I make sense...

For a warm up, Samuel runs 200 yards less than half the maximum distance he can run. This is represented by the equation r = 1/2x-200 where x represents the maximum distance he can run and r represents the distance run during his warm up. If Samuel ran 1,600 yards during his warm up, what is the maximum distance he can run?
3,600 yards
1,600 yards
2,400 yards
1,800 yards
Answer:
A or 3,600 yards
because it more than half of the max distance he can run
Step-by-step explanation:
It says For a warm up, Samuel runs 200 yards less than half the maximum distance he can run. Which means he can run MORE than half that amount and 3,600 yards is the only one that's even doubble the warm up distance
plz give brainliest
Answer:
3,600 yards
Step-by-step explanation:
1600 + 200
=1800 ( 2/1)
1/2 x -200
+ 200
= 1/2 x (2/1)

find the buying price when 5% sales tax is added on the purchase of 5kg of wheat at 20 per kg
Answer:
$300
Step-by-step explanation:
5% of x + 5 kg = 20
0.05 * x + 5 = 20
0.05x + 5 = 20
0.05x = 20 - 5
0.05x = 15
x = 15 / 0.05
x = $300
The perimeter of the rectangle below is 42 inches. Find the value of X.
Please help
Answer:
x = 4
Step-by-step explanation:
42 = 5x + 5x + ( x - 3 ) + ( x - 3 )
42 = 12x - 6
48 = 12x
x = 4
Perimeter is the length around the rectangle (or any other shape). For rectangles, it's found by adding the side lengths. In this case, it required algebra to solve for x.
Answer:
x = 4
Step-by-step explanation:
The opposite sides of a rectangle are congruent.
The perimeter is the sum of the 4 sides, thus
2(5x) + 2(x - 3) = 42 ← distribute parenthesis and simplify left side
10x + 2x - 6 = 42
12x - 6 = 42 ( add 6 to both sides )
12x = 48 ( divide both sides by 12 )
x = 4
Carli has 90 apps on her phone. Braylen has half the amount of apps as Theiss. If Carli has three times the amount of apps as Theiss, how many apps does Braylen have?
Answer:
Braylen has 15 apps on his phone
Step-by-step explanation:
Carli has 3 times the amount of apps that Theiss does
So we divided 90 by 3
90 ÷ 3 = 30
Now we divide 30 by 2 to find out how many apps Braylen has, since he has half the amount of apps that Theiss does
30 ÷ 2 = 15
So Braylen has 15 apps

450 meals served at 75 campus cafeteria 98 had less than 10 grams of fat but not less than 350 calories;110 had less than 350 calories but not less than 10 grams of fat
Incomplete question. The remaining question read;
What percentage of meals had less than 10 grams of fat? Round your answer to the nearest tenth of a percent.
Answer:
21.7%
Step-by-step explanation:
Remember, we are told that 98 out of the 450 meals served at 75 cafeterias had less than 10 grams of fat.
To calculate the percentage, we divide 98 by 450 and then multiply by 100:
[tex]\frac{98}{450}*100=[/tex] 21.7% approximately to the nearest tenth of a percent.
a chord of 12cm long of 8cm is away from the of the circle what is the lenght of the chord which is 6cm away from the centre
Answer:
The length of the chord is 16 cm
Step-by-step explanation:
Mathematically, a line from the center of the circle to a chord divides the chord into 2 equal portions
From the first part of the question, we can get the radius of the circle
The radius form the hypotenuse, the two-portions of the chord (12/2 = 6 cm) and the distance from the center to the chord forms the other side of the triangle
Thus, by Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides
Thus,
r^2 = 8^2 + 6^2
r^2= 64 + 36
r^2 = 100
r = 10 cm
Now, we want to get a chord length which is 6 cm away from the circle center
let the half-portion that forms the right triangle be c
Using Pythagoras’ theorem;
10^2 = 6^2 + c^2
c^2 = 100-36
c^2 = 64
c = 8
The full
length of the chord is 2 * 8 = 16 cm
Help pleaseee! Greatly appreciated if you do
Help! Find the value of X. Thank you. (:
Answer:
x = 4
Step-by-step explanation:
The smaller triangle is an equilateral triangle, so all sides and angles are the same. We know that one side is labeled as 5, so all sides of that little triangle are 5.
The bigger triangle is an isosceles triangle because those two angles are marked as congruent. So, line JM and line KM are congruent as well.
The little triangle and the big triangle share side KM, so KM is equal to 5.
If JM is equal to KM and KM is equal to 5, JM is also five. That means:
x + 1 = 5
Subtract 1 from each side.
x = 4
And there we go.
