what is 1+2=? i need to know if it’s 2 or 12

Answer:

3.5hour

Step-by-step explanation:

Average speed = Distance/Time

Given

Distance = 52 1/2 km

Speed = 15km/hr

Required

Time

Substitute the given values in the formula

Time = (52 1/2)/15

Time= 105/2 * 1/15

Time = 105/30

Time  = 3.5hour

hence it will take 3.5hr to travel a distance of 52 1/2km

Answer:

x = 19.6

Step-by-step explanation:

By applying cosine rule in ΔBCD,

cos(30)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

              = [tex]\frac{BC}{BD}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{BC}{16}[/tex]

BC = [tex]8\sqrt{3}[/tex]

Now, by applying sine rule in ΔBAC,

sin(45)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{AB}{BC}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{x}{8\sqrt{3}}[/tex]

x = [tex]8\sqrt{6}[/tex]

x = 19.59

x ≈ 19.6  

Step-by-step explanation:

General equation: y = 2 + c/(x - 1)

When x = 4, y = 4.

=> (4) = 2 + c/(4 - 1), c = 6.

Hence the equation is y = 2 + 6/(x - 1).

Answer:

[tex]x=\frac{21}{4}[/tex]

Explanation:

[tex]\frac{2x+3}{15}\cdot \:10=\frac{9}{10}\cdot \:10[/tex]

[tex]2x+3-3=\frac{27}{2}-3[/tex]

[tex]\frac{2x}{2}=\frac{\frac{21}{2}}{2}[/tex]

[tex]x=\frac{21}{4}[/tex]

[tex]=5,25[/tex]

Answer:

Ben would earn $280 by selling 140 hot dogs.

Step-by-step explanation:

You do this by multiplying 140 x 2,

If this equals 280, then you would do 70 x 2 to make it even

If this equals 140,

Ben will sell 140 hotdogs, and make $280

Answer:

150 hot dogs

Step-by-step explanation:

1 hot dog is $2 so 140 hot dogs=$280 so if u add 10 hot dogs that would be $20 so $280+$20=$300 which is equal to 150 hotdogs

Answer:

53130

Step-by-step explanation:

It's a combination question.

You just have to calculate:

[tex]C=\frac{25P5}{5P5}[/tex]

That means: [tex]\frac{25x24x23x22x21}{5*4*3*2*1}[/tex]

And that would equal: [tex]\frac{6375600}{120} = 53130[/tex]

Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

Given that Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan, to determine, if Nolan has a total of 23 pens and pencils, and so does Fiona, the number of pens and pencils that either Nolan or Fiona has, the following calculation must be performed:

Therefore, Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

Step-by-step explanation:

Answer: n = 0

Step-by-step explanation: Let's solve for n, according to the linear equation given, this way:

10n + 0.3 = 0.1n + 0.3

10n - 0.1n = 0.3 - 0.3 (Like terms)

9.9n = 0

n = 0/9.9

n = 0

Answer:

5/8

Step-by-step explanation:

For khan the full correct answer is Shrinks by 5/8.

Every second, the horizontal velocity of the ball shrinks v by a factor of 5/8.

A function is a law that relates a dependent and an independent variable.

The horizontal velocity in relation with elapse time is given by

[tex]\rm V(t) = 4 x(\dfrac{5}{8})^t[/tex]

The rate of change of the the horizontal velocity of the ball is given by [tex]\rm (\dfrac{5}{8})^t[/tex]

Every second, the horizontal velocity of the ball shrinks v by a factor of

[tex]\rm (\dfrac{5}{8})^1[/tex]

= (5/8)

Answer:

The first step would be to add twelve to both sides

Step-by-step explanation:

Answer:

add 12 to both sides

Step-by-step explanation:

What we want to do, is to isolate the variable and the numbers on different sides.

if we divide 5x and -20 by 5, what about -12? It's part of the equation too.

If we add 20 to both sides, the numbers and the variable are on the same side, so we'll need to subtract it back off to isolate both.

If we multiply 12 by (what was there) it won't be isolating the variable or numbers. We'll just be increasing the value of the terms already there.

However, if we add 12 to both sides, we'll be isolating both the variable AND the numbers onto different sides.

therefore, add 12 to both sides.

Hope this helps!
