Anchor: If you start with 50 g of a material, how much is half of that? How much is half of half? How much is half of that?​

Answers

Answer:

Step-by-step explanation:

1/2 of 50 grams is the same thing as 50 divided by 2 which is 25

Now you take 1/2 of 25 grams. That's 25 divided by 2. Use your calculator if you're not sure 25 divided by 2 = 12 and 1/2 or 12.5

I think we're down to 1/2 of 12.5

1/2 of 12.5 is 6 and then 0.5/2 which is 0.25

So 1/2 of 12.5 is 6.25

If I left one out, leave a comment.

Just in case 1/2 of 6.25 = 6/2 = 3

1/2 of 0.25 = 0.25/2 = 0.125

so the answer here is 3.125

If I've misunderstood the question, leave a note for that too.

Step-by-step explanation:

if you memorize the acronym SOH-CAH-TOA (Sin opposite/hypotenuse - cosine adjacent/hypotenuse - tangent opposite/adjacent)

you can easily find the answer

since we are working with sin we're gonna use SOH

we have

Sin(A) = [tex]\frac{12}{37}[/tex]

=> so, x^2 * y^4 * x^3 * y^1

=> x^2 * x^3 * y^4 * y^1

=> x^5*y^5

hope it helps

X^5,y^5 because you add the two and three and get five so it’ll be x to the fifth power then you add four and one but there isn’t a number on the y at the end so that automatically makes it one so add four and one you get five so therefore the answer is x^5,y^5

A donation center has 44 small bins with 24 caned food in them they wanna give each food bank the same amount of food there are 4 food banks

Answers

Complete question :

A donation center has 44 small bins with 24 caned food in them they wanna give each food bank the same amount of food there are 4 food banks. How many cans should they give to each food bank?

Answer:

264 cans

Step-by-step explanation:

Number of bins = 44

Number of canned food per bin = 24

Total number of canned foods = (number of bins * number of canned food per bin)

Total number of canned foods = 44 * 24 = 1056

Food is to be distributed equally among 4 banks :

Number of food per bank = 1056 / 4 = 264

–8 ≤ 2x – 4 < 4


A. –2 ≤ x < 4


B. –6 ≤ x < –2


C. –2 ≤ x < 0


D. 0 ≤ x < 6

Answers

Answer:

The Answer is A

Step-by-step explanation:

-8 < 2x-4<4

2x-4<4

-8+4< (2x-4)+4

(2x-4)+4 <4+4

In order to solve these simultaneous inequalities, we need to write them as two separate inequalities, and find the values of x that satisfy both of them.

2x-4<4 In order to solve this linear inequality, we need to group all the variable terms on one side, and all the constant terms on the other side of the inequality.

For example,

- term -4 , will be moved to the left side.

Notice that a term changes sign when it 'moves' from one side of the inequality to the other.

The result is:

A

help me please?! its math question

x = 23
Angle H= 39°
Angle I = 118°
Angle J = 23°

The sum of all angles inside a triangle is 180°.

Your equation: (2x -7) + (5x + 3) + x = 180
2x + 5x + x - 7 + 3 = 180
8x - 4 = 180
Your equation in its simplest form:
8x - 4 = 180

Solving for x:
8x - 4 = 180
8x = 184
x = 23

Angle H = 2x - 7
2(23) - 7 = 46 - 7 = 39

Angle I = 5x + 3
5(23) + 3 = 115 + 3 = 118

Checking the math:
39 + 118 + 23 = 180
