Bob order 151/2 pound of cherrys fron the farm,this year they want to order 1 1/4 more pound but then 2/5 of the order they want

noname [10]

Answer:

Percentage of cherries = 60 %

Percentage of berries = 40 %

Step-by-step explanation:

He orders 15 1/2 pounds every year.

He wants more= 1 1/4 pounds

So the total pounds = 15 1/2 + 1 1/4

= 15 + 1 + 1/2 + 1/4

= 16 + (2+1)/4

= 16 + 3/4

= 16 3/4 pounds

Out of 16 3/4 pounds they want 2/5 part to be of blue berries.

So blue berries = 16 3/4 * ( 2/5)

= 67/4 * ( 2/5)

= 67/10 = 6 7/10 pounds

Amount of cherries= 16 3/4- 6 7/10

= 10 3/4- 7/10

= 10 (15- 14)/20

= 10 1/20 pounds

Percentage of cherries = Amount of cherries/ Total amount * 100

= 201/20 / 67/4 *100

= 201/20 * 4/67 *100

= 201/335 *100

= 60 %

Percentage of berries = 100- 60 = 40 %

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

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