Answer:

(7, 3)

Step-by-step explanation:

Using the midpoint formula

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

X = ax1+bx2/a+b

X = -5(1)+3(11)/1+3

X = -5+33/4

X = 28/4

X = 7

Y = ay1+by2/a+b

Y = 1(12)+3(0)/1+3

Y = 12/4

Y = 3

Hence the coordinate of P is at (7, 3)

Answer:

200 questions

Step-by-step explanation:

Given data

Let the total questions be x

so that

21% of x= 42 questions

let us solve for x

21/100*x= 42

0.21*x= 42

0.21x= 42

Divide both sides by 0.21

x= 42/0.21

x= 200 questions

Hence the questions are 200 questions

Answer:

Step-by-step explanation:

The midpoint of any line segment is the average of the coordinates of the endpoints.

mp=((x2+x1)/2, (y2+y1)/2), in this case we have points (9,7) and (5,3) so

mp=((9+5)/2, (7+3)/2)

mp=(7,5) (x=7 and y=5)

Answer:

0.20 dollar per oz and Joshua brought 16 oz of strawberry

Step-by-step explanation:

1 lbs = 16 oz

3.20÷ 16

= 20 cent

20 cent per one ounce of strawberry

1 cent = 0.01 dollar

20 cent = 20 × 0.01

20 cents = 0.2 dollar

Answer:

Step-by-step explanation:

this is confusing b/c they are asking about two trains traveling at differnt speeds, but.. if you put the speeds together and make one train... imaginary.. ofc... traveling at the speed of both trains combined... when will it be 50 miles from the station?

maybe you can solve that?   I'll solve it below.. but.. if you can.. try it now, on your own

below is my answer... don't look until you have solved yours :P

80+70= 150kph

when will this have traveled 50Km?

you may be able to see that it will take 1/3 of an hour to travel 50 km

so 60 minutes times 1/3 = 20 minutes  :)

Answer:

Part A is no because after subtracting it is 6/10 and 6/10 is not equal to 1/2

Step-by-step explanation:

First you make the fraction's denominator equal

2/5 = 4/10

Camen's water bottle is 1 8/10

Jorge's water bottle is 2 4/10

1/2 = 5/10

Make the fractions into a improper fraction

Camen's is 18/10

Jorge's is 24/10

subtract it

24 - 18 = 6

So Part A is no because after subtracting it is 6/10 and 6/10 is not equal to 1/2

Answer:

  11, 5

Step-by-step explanation:

Zeros are the values of x that make the product zero. The product will be zero if and only if one or more of the factors is zero.

  x -11 = 0   ⇒   x = 11

  x -5 = 0   ⇒   x = 5

The values x=11 and x=5 are zeros of the quadratic.

Answer:

Inequality representation :

18 + 25t ≤ 143 ;

t = 5

Step-by-step explanation:

Given that:

Initial dive, I = 18 feets

Descent rate, r = 25 feets / minute

Maximum depth reached = 143 feets

Time = t

Inequality representation :

18 + 25t ≤ 143

To solve for t

25t ≤ 143 - 18

25t ≤ 125

Divide both sides by 25

25t / 25 ≤ 125 / 25

t ≤ 5

Answer:

2.4 inches

Step-by-step explanation:

Actual Dimension of bedroom = 10' * 8'

In the model ; longer side = 3 inches

Length of shorter side in the model ;

Longer side of actual bedroom = 10'

Scale factor * length = model length

Scale factor * 10 = 3

Scale factor = 3/10

Hence, length of shorter side :

Scale factor * actual length of shorter side

3/10 * 8

24 / 10

= 2.4 inches

wrote on NEML, got it right,

Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds. The millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

Given information

All three cars can travel the same distance on a tank of gas.

The second car gets 6 kilometres per liter more than the first, but its tank holds 3 fewer liters than the first.

The third car gets 6 kilometres per liter less than the first, but its tank holds 6 more liters than the first.

Suppose the first car runs m. kilometre per liter. Then the second car will run (m+6) kilometre per liter and third car runs (m-3) kilometre per liter.

Suppose the first car has l liter in the tank. Then the second car has (l-3) liter and third car has (l+6) liters in her tank.

Distance traveled by an car is the ratio of the mileage gives by the car to the total fuel the tank holds.

As the distance traveled by the first car is same as the second one. Hence,

[tex]\begin{aligned}\\\dfrac{m}{l} &=\dfrac{m+6}{l-3} \\ml-3m&=ml+6l\\m&=-2l\\\end[/tex]

Let the above equation is equation 1.

As the distance traveled by the second car is same as the third one. Hence,

[tex]\begin{aligned}\\\dfrac{m-3}{l+6} &=\dfrac{m+6}{l-3} \\ml-3m+9-3l&=ml+6l+6m+36\\l+m&=-3\\\end[/tex]

Put the value of m in the above equation from equation 1,

[tex]l-2l=-3\\l=3[/tex]

[tex]m=2\times3=6[/tex]

Thus the value of the m is 6.

With the millage of 6 kilometre per liter in 3 liter the cars can travel 18 kilometre.

Answer:

The right solution is "18". A further explanation is given below.

Step-by-step explanation:

The given series is:

1,2,4,8,12

Here,

First term,

a₁ = 1

Second term,

a₂ = 2

Last term,

n = 12

Now,

The sum of the sequence will be:

⇒ [tex]S_n = \frac{n ( a 1 + a 2 ) }{2}[/tex]

On substituting the values, we get

⇒      [tex]=\frac{12(1+2)}{2}[/tex]

⇒      [tex]=\frac{12\times 3}{2}[/tex]

⇒      [tex]=\frac{36}{2}[/tex]

Answer:

b + r = 10 - - (1)

2r + 3b = 23 - - (2)

Step-by-step explanation:

Number of Blue pens in box A = b

Number of red pens in box A = r

BOX A :

Contains 10 pens that are either red or blue

b + r = 10

BOX B:

Contains 23 pens that are either red or blue ;

Red pens in box B = 2 tines the number of red pens in box A

Blue pens in box B = 3 times the number of blue pens in box A

2r + 3b = 23

The correct expression will be ( x- 4 ). So option B is right.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The expression will be solved as:-

E = ( - √(x-4))²

The product of two minuses is positive and the product of the same square root numbers will be the number so the equation will become.

E = -√(x-4) x -√(x-4)

E = x - 4

Therefore the correct expression will be ( x- 4 ). So option B is right.
