Which is another way to check the sum of 104 + 34 + 228 + 877?

weqwewe [10]

By adding 104+34 and then 228+877, Then adding both of the results and finally subtracting the answer by one of the factors.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Explanation:

Which will be...

104+34=138

228+877=1,105

Then add them...

138+1,105=1,243

Finally, subtract your answer by one of the factors...

1,243-1,105

Which will result as 138. Which is also one of the factors you added earlier, that's basically what your looking fro when checking and subtraction and/or addition problem.

Nancy wants to receive the most return on a $50,000 investment. She has two options. Option 1 gives annual interest at 5% compou

Annette [7]

Answer:

Option 1 earns more interest by $2396.13

Step-by-step explanation:

Step 1: Determine the prices

50000(1 + 0.05)^3 = 57881.30

50000(1 + 0.0035/12)^36 = 55527

Step 2: Determine which pays higher

Step 3: Find difference

57881.30 - 55527 = 2396.13

And we have our final answer!

point A is at (-2,-7)and point M is at(2.5,-1.5). Point M is the midpoint of point A and point B.what are the coordinates of poi

Scrat [10]

Answer:

B (7, 4 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ ] ← midpoint formula

let coordinates of B = (x, y ), then using the midpoint formula, equate to each of the coordinates of M, that is

$\frac{-2+x}{2}$ = 2.5 ( multiply both sides by 2 )

- 2 + x = 5 ( add 2 to both sides )

x = 7

$\frac{-7+y}{2}$ = - 1.5 ( multiply both sides by 2 )

- 7 + y = - 3 ( add 7 to both sides )

y = 4

Thus

coordinates of B = (7, 4 )

Find 0,8,3 round the nearest degree

MArishka [77]

The measure of $\theta$ is 68 degrees

<h3>How to solve the angle?</h3>

The complete question is in the attached image

The value of $\theta$ is calculate using the following cosine function

$\cos(\theta) = \frac 38$

Evaluate the quotient'

$\cos(\theta) = 0.375$

Take the arc cos of both sides

$\theta = \cos^{-1}(0.375)$

Evaluate the arc cos

$\theta = 67.97$

Approximate to the nearest degree

$\theta = 68$

Hence, the measure of $\theta$ is 68 degrees
