Answer:

a) 7/4 b) 15/2

Step-by-step explanation:

a) Scale Factor = Image / Object

Take the side of Triangle ABC that's BC Why? Because it corresponds with the Image Triangle ADE's DE

= 21/12 = 7/4

b) 7/4 = 10+ x / 10

Cross Multiply

= 4 ( 10 + x ) = 70

= 40 + 4x = 70

= 4x = 70-40

= 4x = 30

= 4x/4 = 30/4

x = 15/2

HELP PLZ!!!!- In 2012, on average, about 9.46 × 10^-1 pound of potatoes was produced for every 2.3 × 10^-5 power acre harvested.
sashaice [31]

Answer:  The answer is 41.13 pounds (approx.).


Step-by-step explanation:  Given that the average production of potatoes in 2012 was 0.946 pounds for every 0.000023 power acre harvested. We need to calculate the pounds of potatoes produced on average for each acre harvested.

For that, we need to divide the pounds of potatoes by number of acres harvested.

In 0.000023 acre harvested, ponds of potatoes = 0.946 ponds.

Therefore, in 1 acre harvested, pounds of potatoes is given by

p=\dfrac{0.946}{0.000023}=41.13~\textup{(approx.)}

Thus, the answer is 41.13 pounds (approx.).

Question below please!
aliina [53]

Answer:

b = √45

Step-by-step explanation:

From the figure we  get, There are two right angled triangle.

In large triangle 'b' is the base, height = 6 and hypotenuse = 9

<u>To find the value of  b</u>

Hypotenuse² = Base² + Height²

Here,

9² = b² + 6²

b² = 9² - 6² = 81 - 36 = 45

Therefore, b = √45

Each leg of a 45°-45°-90° triangle measures 12 cm. What is the length of the hypotenuse? 6 cm cm 12 cm cm
sasho [114]
The legs are 12 cm each, so the hypotenuse is
√(144+144)=12√2
