Answer:

y = 9 cm

Step-by-step explanation:

The 2 triangles are similar ( by AA postulate ) , then the ratios of corresponding sides are in proportion , that is

\frac{y}{6} = \frac{15}{10} = 1.5 ( multiply both sides by 6 )

y = 6 × 1.5 = 9 cm

The value of y from the diagram is 9

<h3>Similar shapes</h3>

From the given figure, the shapes are similar, using the similarity theorem of triangles, you ill have;

6/10 = y/15

Cross multiply

10y = 15* 10

10y = 90

y = 90/10

y = 9

Hence the value of y from the diagram is 9

Sheldon harvests the strawberries and tomatoes in his garden. He picks 1 2/5 kg less strawberries in the morning than in the aft
Natalija [7]

Let

x ----> kilograms of strawberries that Sheldon picks in the morning

y ---> kilograms of strawberries that Sheldon picks in the afternoon

so

we have that

x=y-1 2/5

x=2 1/4 kg

substitute

2 1/4=y-1 2/5

Convert mixed numbers to an improper fraction

1 2/5=1+2/5=7/5

2 1/4=2+1/4=9/4

substitute

9/4=y-7/5

y=(9/4)+(7/5)

y=(45+28)/20

y=73/20 kg

Adds kilograms in the morning and afternoon

x+y=(9/4)+73/20)

x+y=(45/20)+(73/20)

x+y=118/20 kg

Convert to mixed number

118/20=100/20+18/20=5+18/20=5+9/10=5 9/10 kg

therefore

<h2>The answer is 5 9/10 kg</h2>

To write this as the image, we simply have to add a mark on the A

This mark is at the upper right

We have it as A’ (x,y)

Line AB is tangent to circle C, AB= 4 inches, and AD = 2 inches. Find the radius of the circle.
Mariulka [41]
Let the radius of the circle be x, then by the tangent-secant theorem
4^2 = 2(x + 2)
16 = 2x + 4
2x = 16 - 4 = 12
x = 12/2 = 6

Therefore, the radius of the circle is 6 inches.
