28/7=4km is car journey covered by car in 1l

64/4=16l

The car would use 16 liters of petrol to cover 64 km.

To find out how many liters of petrol the car uses to cover 64 km, we can set up a proportion using the given information. Since the car uses 7 liters of petrol to cover 28 km, we can say that the fuel consumption rate is 7 liters per 28 km. To find out the fuel consumption rate for 64 km, we can set up the proportion:

7 liters / 28 km = x liters / 64 km

Cross-multiplying, we get 28x = 7 * 64.

Dividing both sides by 28, we get x = 7 * 64 / 28 = 16 liters. Therefore, the car would use 16 liters of petrol to cover 64 km.

20,

So, there are 6 total parts,

X = 60/6

Each X = 10

So, 10*2 = 20

20 of them are golden.

To determine the number of golden nail paints, the total nail paints (60) are divided by the sum of the ratio parts (3), resulting in 20 nail paints per part. Multiplying the part for golden paints (1) by 20 gives us 20 golden nail paints.

The ratio of silver nail paints to golden paints is given as 4 to 2, which simplifies to a ratio of 2 to 1. This means that for every 2 silver nail paints, there is 1 golden nail paint. If there are a total of 60 nail paints, we need to determine how many of them are golden. To find out, we divide the total number of nail paints by the sum of the ratio parts (2 + 1 = 3 parts). Hence, each part represents 20 nail paints (60 ÷ 3).

To calculate the number of golden nail paints, we then multiply the number of parts for golden paints (which is 1 part) by the nail paints per part, so we get 20 x 1 = 20 golden nail paints.

So, The discontinuity would be at 1, since plugging in one for x would yield a zero in the denominator (It would be a non-removable one).

Answer: A.15

Step-by-step explanation:

We know that the mode of a data set is a data value that occurs most of the time than the rest other values.

Given : A group of college students was surveyed to see how old they were when they had their first job.

The results were as follows:

:15% were 14 years old;

50% were 15 years old;

20% were 16 years old;

15% were 17 years old.

We can that the highest percentage (i.e. 50% ) is of 15 years old students.

It means that the mode of the data set is 15 .

Hence, the correct answer is option (A).

You start from right to left, the third number is always the hundred place, the second number (6 in your case) is the tens place, and 5 is in the ones place. So your correct answer is 3 or B

78.2% means that out of 100, 78.2 DO study. 100-78.2 gives you the amount of students that dont study (including me lol) which comes out to 21.8 . so since 21.8 out of 100 dont study, you can divide 21.8/100, and get your answer.

the answer is a

Hello there! Thank you for asking your question here on brainly.

Answer: C. <3

Why?

We have 4 angles on each side. We have two sets of angles, so we have 8 angles. To tell how angles correspond, find where they are on the other side. Example, in this, the (2) on the top set of angles it on the top right. To find which one corresponds to the second one, look at the top right of the second set. 6 would be the answer to that. The (3) in this is on the bottom left on the first set, and the 7 on the second set is in the same place, the bottom left.

Answer:

9, 7,-8.3,>

Step-by-step explanation:

5)-3 is marked exactly 3 units to the left of origin 0.

(since negative sign we mark on left of 0)

6) |-9| = absolute value of 9 = 9

7) y-11=-4

Add 11 to both the sides

WE get y =7 is the solution

8) a + b when a = 2.5 and b = -10.8.

= 2.5+(-10.8) = -(10.8-2.5) = -8.3

9) 0.4 is positive hence lies to the right of origin.

Partition the space between 0 and 1 into 10 equal subparts and mark 4th subdivision to get 0.4

10) -1.8>-2.5

we know that

If DF is parallel to GH

then

the measure of the angle EGH must be equal to 70° by corresponding angles

so

Find the measure of the angle EGH

In the triangle EGH

the sum of the internal angles must be equal to 180 degrees

42°+68°+∠EGH=180°

solve for ∠EGH

∠EGH=180-(42+68)

∠EGH=180-110

∠EGH=70°

therefore

The lines DF and GH are parallel

A handy conversion to remember is that 60 mph equals 88 feet per second.

Therefore, 50 mph will be (5/6) of 88 feet per second or 73.3333333333 feet per second.

For this case we must factor the following expression:

[tex]x ^ 2-12x + 36[/tex]

We must find two numbers that when multiplied give as a result "36" and when added together they give "-12". These numbers are:

[tex]-6-6 = -12\\-6 * -6 = 36[/tex]

Then, the factorization is given by:

[tex](x-6) (x-6) = (x-6) ^ 2[/tex]

Answer:

[tex](x-6) ^ 2[/tex]

Answer:

The given equation is

⇒y≥[tex]\frac{1}{3x-2}[/tex]

As domain of the function is 3 x-2≠0

             x≠2/3

⇒For different values of x we get different values of y.

When,  x>2/3 , we get positive values of y.

So , y≥ 0

and  when x< 2/3 , we get values of y which are negative.

i.e y≤0

At x=2/3, function is not defined.So at that point there does not exist any value of y.

Answer with explanation:

Width of the field = w  feet

As, given length of rectangular field is 40 feet more than twice the width.

Length of Soccer field = (2 w + 40) feet

Area of Rectangular field = Length × Breadth

                                          = w × (2 w+40)  square feet

                                       A =2 w² +40 w

First Blank =2

Second Blank = 40

varies directly means [tex]\frac{y}{x} = k[/tex]

inserting y = -18 and x = 3 ⇒   [tex]\frac{-18}{3} = k[/tex]   ⇒   -6 = k

next, insert k = -6 into the varies directly equation and solve for y. y = -6x

Answer:

Option 2 is correct that is NO ; The triangles are not similar.

Step-by-step explanation:

Given: Measurements of the sides of triangle.

Say sides of triangle 1 = 3 , 5 , 6

Sides of triangle 2 = 4 , 6 , 8

We have to find if triangles are similar or not and if they are similar then to find their ratio.

Since, We are given with only sides of the triangle.

Then if they are similar then they will be by Side-Side-Side similarity criteria.

Here, Two triangles are said to be similar by Side-Side-Side Criteria if ratio of their sides are equal.

But clearly from given values , all ratios are not equal.

[tex]\frac{3}{4}=\frac{6}{8}\neq\frac{5}{6}[/tex]

Or

[tex]\frac{3}{6}\neq\frac{5}{8}\neq\frac{6}{4}[/tex]

No possible pair give equal ratio.

Therefore, Option 2 is correct that is NO ; The triangles are not similar.

[tex]24 * 10^4[/tex]

In power of ten notation, exponent tells us that how many times 10 is to be multiplied by itself to equal the number we wish to write. So we can write the above scenario as follows:

[tex]240,000 * 10^0[/tex]

[tex]240, 00 * 10^1[/tex]

[tex]240, 0 * 10^2[/tex]

[tex]240 * 10^3[/tex]

[tex]24 * 10^4[/tex]

So, the 10 will be multiply 4 times with 24 to get the same answer as 240,000

The answer is [tex]24 * 10^4[/tex]

Step-by-step explanation:

The number is = 92776

Explanation:

my nine is worth 9 x 10000 , this gives-

[tex]9\times10000=90000[/tex]

my two it's worth 2001 =2 (thousandth place)

sevens is worth 70(tens place) the other is worth 10 times (hundredth place) = 77

my other digit is at 6 =6

Hence, 92776

Remark

Multiply both sides of the equation by 25. Then you have an equation that you have already done probably.

Step One

Multiply both sides of the equation by 25

1 * (20 - t) = 4t - (3/5) * 25    Every part of the equation must be multiplied by 25

(20 - t) = 4t - 75/5                 3*25/5 = 75/5

20 - t = 4t - 15                       Add t to both sides

20 - t + t =4t + t  - 15             Combine like terms

20 = 5t - 15                            Add 15 to both sides

20 + 15 = 5t - 15 + 15             Combine like terms  

35 = 5t                                    Divide by 5

35/5 = 5t/5                             Switch sides

Answer:

Refer below

Step-by-step explanation:

A function is said to be increasing if y increases whenever x increases and y decreases whenever x decreases.

A function is decreasing if y increases when x decreases or vice versa.

Hence from the graph we find that when the curve is going up when we move to right the function is increasing otherwise decreasing.

f(x) attains its extreme values at x = -8, -3, 2 and 6

Left of -8 we find f(x) is increasing.

ie.(-infty, -8) increases, (-8,-3)decreases, (-3,2) increases, (2,6) decreases and (6,infty) increases

To consolidate increasing in (-infty, -8)U(-3,2)U(6,infty)

and decreses in (-8,-3)U(2,6)

Option C

{-1,3,5}

Step-by-step explanation:

A mapping is a subset of ordered pair (x,y) where x belongs to first set and y belongs to second set.

Hence a mapping is a subset of cartesian product AXB.

Here A = {-2,1,3,5} and

B = {2,4,6,8}

Ordered pair given by the mapping is

(-2,1) (3,6) and (5,8)

In other words, -2 is mapped on to 1, 3 to 6 and 5 to 8

Domain = set of elements in the I set which are mapped

= {-1,3,5}
