I am pretty sure the answer is D because you add 4 to start and then you move back (-) 9 points

70,000 devided by 7,000

marusya05 [52]

It would be 10 because 7000 can go into 70,000 10 times. You can you a calculator or look at the zeros take away the 3 zeros in 7000 and then 3 zeros in 70,000 making it 7 and 70 and 7 goes into 70 10 times as well. I hope this helps!

What is the solution to the equation x + 7.5 = 21.5? A.x = 2.9 B.x = 7.8 C.x = 14 D.x = 29

dedylja [7]

X+7.5=21.5
Subtract 7.5 from both sides
X=14 which is C
hope this helps good luck have a nice day

Question is below in picture.

Maurinko [17]

Answer:

C. $\sqrt{89}$ cm

Step-by-step explanation:

First, we can start out by stating that this is a right triangle, since it has a right angle, shown by the marker square in the corner of the triangle. The x part, is called the hypotenuse. When finding the value of the hypotenuse, we use a thing called the Pythagorean Theorem. This theorem is :

a^2 + b^2 = c^2

a is one side length, and b is the other. c is the hypotenuse. To find x, the hypotenuse, we simply plug in the values, and solve.

8^2 + 5^2 = c^2

64 + 25 = c^2

89 = c^2

To get c alone, we do the square root of 89.

$\sqrt{89}$ = c

9.43398113 = c

So, the answer is C. $\sqrt{89}$ cm

The 200th term of the arithmetic progression 10 97,94,91,.............is

azamat

Answer:

-500

Step-by-step explanation:

Given sequence;

97, 94, 91 ......

Unknown;

The 200th term of the sequence;

Solution:

Since we were given an arithmetic progression, we need to first find the common difference;

Common difference = second term - first term

= 94 - 97

= -3

To find the 200th term, we use the expression below;

Sn = a + (n-1)d

a is the first term

n is the nth term

d is the common difference

S₂₀₀ = 97 + (200 - 1 ) x -3 = -500
