For every hour driven (60 minutes) the person will drive 60 miles, therefore it will travel a distance of 60 miles in 60 minutes

Answer:

Graph #2 for sure, both axis are linear and the curve is a parabola all right.

On graph #1: I can't for the life of me read the units on the Y axis, so you have to check: if they're going 2000 4000 6000, then that is a parabola as wel. If they're increasing esponentially, ie 2000 4000 8000, then one of the two axis is logarithmical and the curve is no longer quadratic.

There are 30 adults in the swimming pool.

The ratio is a quantitative approach that shows the relation between two proportions.

From the given relation, the ratio of of the children to adults = 8 : 3

The total number of the ratio = 8 + 3 = 11

Given that there are 110 people in the population.

The number of adults that are there will be:

[tex]\mathbf{=\dfrac{3}{11}\times 110}[/tex]

= 30 adults

Answer:

Between the edges of the first two triangles there is a ratio. To find this ratio, you need to ratio one edge of a small triangle to one edge of a large triangle. So 5/30=6/36=8/48=1/5. The ratio we want to find is 1/5 or 5.

Answer:

2 x 7

Step-by-step explanation:

4 x 7 = 28

Since you want doubled, we have to half to find start.

28/2 = 14

Only solid equation that equals 14 is 2 x 7

And since 4 is a double of 2, the answer checks out

The multiplication fact that can be doubled to find 4 x 7 is

2 x 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

4 x 7 = 28

Now,

The multiplication of 2 x 7 = 14.

If 2 x 7 is double we get,

2 x (2 x 7) = 2 x 14 = 28

Thus,

The multiplication fact is 2 x 7.

Step-by-step explanation:

subtract how much he paid for the car with how much he paid down

2150-750=1400

then subtract that by the 95 dollars he paid off in the first month

1400-95=1,305

He still needs to pay off $1,305.

Answer:

[tex]<174\frac{4}{9}[/tex] hopes this helps :D

Step-by-step explanation:

The solution is s > 174 4/9

The inequality equation is s > 174 4/9 and it will take 174 4/9 seconds for the hot air balloon to reach below 215 feet

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is given by

Let the total altitude of the hot air balloon be = 1000 feet

Now , the hot air to reach below 215 feet , the hot air balloon should descend a total of = 1000 - 215 feet

So , the value of hot air balloon should descend = 785 feet

And ,

The rate at which the hot air balloon descends = 4 1/2 feet per seconds

So , the number of seconds s for the hot air balloon to reach an altitude more than 785 feet is given by the inequality equation A

where ( 4 1/2 ) x s > 785

On simplifying the equation , we get

( 4 1/2 )s > 785

( 9/2 ) s > 785

Multiply by 2 on both sides of the equation , we get

9s > 1570

Divide by 9 on both sides of the equation , we get

s > 174 4/9

Therefore , the value of A is s > 174 4/9

Hence ,

The inequality equation is s > 174 4/9 where s is the number of seconds

Answer:

{a,c,d,b} = {49/16,29/16,2,-31/48}

Step-by-step explanation:

  [1]    3a + c - 4d = 3

  [2]    -4a + 4c + d = -3

  [3]    -a - 2d + 3b = -9

  [4]     - d = -2

// Solve equation [4] for the variable  d

  [4]    d = 2

// Plug this in for variable  d  in equation [1]

  [1]    3a + c - 4•(2) = 3

  [1]    3a + c = 11

// Plug this in for variable  d  in equation [2]

  [2]    -4a + 4c + (2) = -3

  [2]    -4a + 4c = -5

// Plug this in for variable  d  in equation [3]

  [3]    -a - 2•(2) + 3b = -9

  [3]    -a + 3b = -5

// Solve equation [1] for the variable  c

 [1]    c = -3a + 11

// Plug this in for variable  c  in equation [2]

  [2]    -4a + 4•(-3a+11) = -5

  [2]    -16a = -49

// Solve equation [2] for the variable  a

  [2]    16a = 49

  [2]    a = 49/16

// Plug this in for variable  a  in equation [3]

  [3]    -(49/16) + 3b = -5

  [3]    3b = -31/16

  [3]    48b = -31

// Solve equation [3] for the variable  b

  [3]    48b = - 31

  [3]    b = - 31/48

// By now we know this much :

   a = 49/16

   c = -3a+11

   d = 2

   b = -31/48

// Use the  a  value to solve for  c

   c = -3(49/16)+11 = 29/16

Step-by-step explanation:

so bd/a+c= 3×(-4)/-2 +(-12)= -12/-2+(-12)=6+(-12)=6-12=-6

so the answer is -6
