Answer:

$1.13

Step-by-step explanation:

Since 6 pound bag of oranges costs $6.78...

$\frac{6.78}{6}$

Now, let's divide 6.78 in to 6 to find our unit price.

$\frac{1.13}{1}$

Now we know 1 pound, (our unit price), costs...

$$1.13$

Assume a and b are whole numbers, and a>b. Which expression has the least value?

dedylja [7]

a > b

A . a^5b^3/ab^4 = a^4/b

B. a^4 / a*a*a*a = a^4 / a^4 = 1

C. ab^2 / a^2b = b/a

D. b*b*b/b^3 = b^3/b^3 = 1

B and D, doesn't matter what values of a and b it's always equal 1

Lets say a = 2 and b = 1

A. a^4/b = 2^4 / 1 = 16/1 = 16

C. b/a = 1/2 = 0.5

So C has the least value

Answer:

ab^2 / a^2b

Find the ratio of the area of triangle XBY to the area of triangle ABC for the given measurements, if BY = 3, YC = 2

Mazyrski [523]

Answer:

The ratio of the area of triangle XBY to the area of triangle ABC is $\frac{9}{25}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

In this problem

Triangles XBY and ABC are similar, because the corresponding internal angles are congruent

see the attached figure to better understand the problem

step 1

Find the scale factor

Let

z-------> the scale factor

$z=\frac{BY}{BC}$

we have

$BY=3\ units$

$BC=2+3=5\ units$

substitute

$z=\frac{3}{5}$

step 2

Find the ratio of the area of triangle XBY to the area of triangle ABC

Remember that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

we have

$z=\frac{3}{5}$ -----> scale factor

$z^{2} =(\frac{3}{5})^{2} =\frac{9}{25}$

Write the linear equation in Slope-Intercept Form y = mx + b of the line that passes through the given points, then graph

natima [27]

Answer:

y = 3x + 7.

To graph the line mark off the 2 points and draw a line through them.

Step-by-step explanation:

The slope = (-2-7) / (-3-0)

= -9/-3

= 3.

The value of b is found using the point-slope form of a line:

y - y1 = m(x - x1)

using m = 3, (x1, y1) = (0, 7):

y - 7 = 3(x - 0)

y = 3x + 7.
