Answer:

8 miles

Step-by-step explanation:

If we divide 70 by 50, we get the unit rate for the ratio 70 minutes for every 50 miles.

70÷50=1.4

So the runner is running 1.4 minutes per mile. We can multiply this unit rate by the number of miles:

1.4 minutes mile × 5 miles = 7 minutes

Thus it will take her 7 minutes to run 5 miles at this pace.

If it takes her 7 minutes to run 5 miles, it will take her 7÷5 = 1.4 minutes to run 6÷3=2 miles at the same pace.

If it takes her 1.4 minutes to run 5 miles, it will take her 1.4×5=7 minutes to run 4×2=8 miles at the same pace. Since 60 minutes is 1 hour, she is running at a speed of 8 miles per hour.

We found her pace in minutes per miles in part (a).

Answer:

Step-by-step explanation:

-3x+4y=4

-5x-3y=26

----------------

-8x+y=30

y=8x+30

Plug 8x+30 back into -5x-3y=26

-5x-3(8x+30)=26

-5x-24x+90=20

-29x=-70

x=2.413

Plug 2.413 into y=8x+30

y=8(2.413)+30

y=19.304+30

y=49.304

Answer:

The answer is 1 953 125

Step-by-step explanation:

(1/5)^(-3)/(1/5)^6

First, we evaluate the resultant power: (1/5)^(-3)/(1/5)^6=(1/5)^(-3-6)=(1/5)^(-9)

Then, we evaluate the value of the expression: (1/5)^(-9)=5^9=1 953 125

Thus, the answer is 1 953 125

Step-by-step explanation:

8x+78°=2x+114°

8x-2x=114-78

6x=36

x=6

B=2(6)+114

B=12+114

B=126°

Note angle A and B are alternate angles and thus are equal

Answer:

since X=6 ,

2×6+114= 126 .

Answer:

25&36

Step-by-step explanation:

25 is a square no and so is 36 and there product is 900. They are also consecutive.

Just assemble the square nos from the least i.e 4 and try solving as asked to see if it gives 900.

Thus u'll land on 25&36

Step-by-step explanation:

x + y = 985

2.95x + 9.95y = 7343.75

-2.95x - 2.95y = -2905.75

7y = 4438

y= 634 steak sandwiches

x + 634 = 985

x = 351 hot dogs

Answer:

634 steak sandwiches

Step-by-step explanation:

h = hot dogs

s = steak sandwiches

First, lets make 2 equations.

2.95h + 9.95s = 7343.75

h + s = 985

We can make the second equation h = 985 - s

Now substitute h into the first equation.

2.95(985 - s) + 9.95s = 7343.75

Distribute the 2.95

2905.75 - 2.95s + 9.95s = 7343.75

Simplify s

2905.75 + 7s = 7343.75

Subtract 2905.75 from both sides

7s = 4438

s = 634

If h = 985 - s and s = 634 we can find h by subtracting 634 from 985

985 - 634 = 351

Now to check:

351 times 2.95 = 1035.45

634 times 9.95 = 6308.3

6308.3 + 1035.45 = 7343.75 so that means our answer is correct.

Hope this helps!!

Answer:

graph 1: f(x) = 3*x^2 - 5*x

graph 2: f(x) = 3*x^2 + 5

graph 3: f(x) = -3*x^2 - 5

Step-by-step explanation:

This is ratter easy if we know some of the main rules for quadratic equations.

For a quadratic equation:

y = f(x) = a*x^2 + b*x + c

if a > 0, then the arms of the graph will open upwards.

if a < 0, then the arms of the graph open downwards.

With this in mind we can look at the graphs, only one of them have arms that open downwards, then the function that matches with this graph should be the only one with a leading coefficient smaller than zero, which is:

f(x) = -3*x^2 - 5

Now, when we have functions like:

y = f(x) = a*x^2 + c

c is the value of y at the vertex.

In graph 2 we can see that the arms open upwards, and that the y-value at the vertex is positive (it is above the horizontal axis)

Then the function of graph 2 should have a positive leading coefficient and a positive constant term.

The function is:

f(x) = 3*x^2 + 5

Then the remaining function is the one that corresponds to graph 1

f(x) = 3*x^2 - 5*x

Then we have:

graph 1: f(x) = 3*x^2 - 5*x

graph 2: f(x) = 3*x^2 + 5

graph 3: f(x) = -3*x^2 - 5
