Answer:

3/4 = 16/x. Step-by-step explanation: Set up the original ratio: 3:4 (a.k.a. 3/4 or 3 to 4) Because 16 correlates to red paint and 3 correlates to red paint the will be in the same location (as the numerator or denominator).. Also, the amount of blue paint is unknown so that is x.4 also represents blue paint, so 4 and x will also be on the same level (as the numerator of denominator).

Drag the correct graph of each equation into the space next to that equation to show how the output y-values change with changes
Jlenok [28]

Answer:

see the explanation and the attached figure

Step-by-step explanation:

Part 1)  Linear

we have

y=x+3

This is the equation of the line in slope intercept form

The slope is positive and equal to m=1

The y-intercept is b=3

As the value of x increases the value of y increases too

As the value of x decreases the value of y decreases too

therefore

The graph in the attached figure

Part 2) Quadratic function

we have

y=3x^2

This is a vertical parabola open upward with the vertex at origin

As the value of x increases the value of y increases too

As the value of x decreases the value of y increases

therefore

The graph in the attached figure

Part 3) Exponential function

we have

y=3^x

This is a exponential growth function

As the value of x increases the value of y increases too

As the value of x decreases the value of y decreases too

The initial value or y-intercept is 3

therefore

The graph in the attached figure

It took Amir 2 hours to hike 5 miles. On the first part of the hike, Amir averaged 3 miles per hour. For the second part of the
rjkz [21]
<h2>Answer:</h2>

The equation that will be used to find t is:

                3(2-t)+1.5t=5

<h2>Step-by-step explanation:</h2>

Total distance that is traveled by Amir is: 5 miles.

and the total time taken by him is: 2 hours.

On the first part of the hike, Amir averaged 3 miles per hour.

Let t denote the time he spent hiking during the second i.e. difficult part of the hike.

  • Hence, the time he spent in first part of hike is: 2-t

( Since, the total time was 2 hours)

Also, we know that:

Distance=Speed\times Time

Hence, distance traveled in first part of hike is:

Distance=3\times (2-t)

  • Now, the distance he will travel in second part of hike will be: 5-3(2-t)

Since the total distance traveled by him is 5 miles.

It is given that his speed decreased to 1.5 miles per hour.

Now, we know that:

Time=\dfrac{Distance}{Speed}

Hence, time spent by him in second part of hike is:

t=\dfrac{5-3(2-t)}{1.5}\\\\i.e.\\\\1.5t=5-3(2-t)\\\\i.e.\\\\3(2-t)+1.5t=5

Haley has 3 3/8 cups of sugar to make pies. If each pie uses 2 1/4 cups of sugar, how many pies can she make?
tester [92]

Answer:

With 3 3/8 cups of sugar Haley can make one and a half  pie.

Step-by-step explanation:

The amount of sugar required to make each pie  =   2 1/4 cup

Now,  2 \frac{1}{4}   = 2 + \frac{1}{4}   = 2 + 0.25  = 2.25

So, Haley uses 2.25 cup of sugar foe  each pie.

Total cups of Sugar Haley has = 3 3/8 cups.

Now,  3 \frac{3}{8}   = 3 + \frac{3}{8}   = 3 + 0.375  = 3.375

So, the total amount of sugar Haley has  is 3.375 cups.

Now, \textrm{Number of pies she can make}  = \frac{\textrm{Total cups of sugar she has}}{\textrm{Cups of sugar required for each cake}}

= \frac{3.375}{2.25}    =1.5

or the number of  pies she can make  =  1.5

Hence, with 3 3/8 cups of sugar Haley can Make 1 1/2 pie.
