Answer:

Step-by-step explanation:

9 x 10^-4: Since the exponent of the scientific notation is negative −4, move the decimal point 4 places to the left. Answer: 0.0009

3 x 10^-10: Since the exponent of the scientific notation is negative −10, move the decimal point 10 places to the left. Answer: 0.0000000003

Subtract: C) 6 x 105

PLZ HELP! WILL MAKE A BRAINLIST Which types of dilation are the given scale factors?

attashe74 [19]

Answer:

see explanation

Step-by-step explanation:

For a given scale factor k

If k > 1 then expansion

If k < - 1 then expansion in the opposite direction

If 0 < k < 1 or - 1 < k < 0 then contraction

k = - 2 ← expansion in opposite direction

k = 1.5 ← expansion

k = $\frac{1}{4}$ ← contraction

k = - $\frac{6}{7}$ ← contraction

How to solve 325x52 traditional way

pentagon [3]

place 325 on top and line up 52 with 25 on bottom. Then multiply 2 with 5 to get 10. Place the zero bellow the line and carry the 1 over the 2. Multiply 2 times 2 to get 4 and then add one to get 5. Put the five bellow the line. Multiply 3 times 2 to get a total of 6 and bring it bellow the line. Bring a zero bellow the 0 that's bellow the line. Multiply 5 times 5 to get 25. Bring the 5 to the left of the zero you just placed and carry the 2. Multiply 5 times 2 to get 10 and add the 12. Place the 2 to the left of the 5 you just placed bellow the line and carry the 1. Multiply 5 times 3 to get 15 and add the 1 to get 16. Place the 16 to the left of the 2 you just placed bellow the line. Then add 650 plus 16250 to get an answer of 16,900.

Wow that was long and hard to explain LOL. :)

What’s the answer?!!!!

mel-nik [20]

Answer: YES

Step-by-step explanation:

Concept

In a right triangle, the square of both legs is equal to the length of hypotenuse squared. This is the Pythagorean theorem: a²+b²=c². For more graphical explanation, please refer to the attachment below.

Given

Leg a = 36 in

Leg b = 48 in

Hypotenuse c = 60 in

Solve

a² + b² = c²

(36)² + (48)² = 3600

(60)² = 3600

3600 = 3600

Therefore, the answer is YES

Hope this helps!! :)

Amanda and jamie are standing 25 feet apart and spot a bird in the sky between them the angle of elevation from Amanda is 25 fee

finlep [7]

Answer:

25.2294 feet

Step-by-step explanation:

We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).

First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:

y + 55 + 63 = 180

y = 62°

The relation between the angles and the distances are:

25 / sin(y) = x / sin(63)

25 / 0.8829 = x / 0.8910

x = 25 * 0.8910 / 0.8829 = 25.2294 feet
