Answer:

Nothing goes into 3

8 goes into 32 four times (8 times 4= 32) so that means you'd put 4 on top of 2

then you bring down the 8 and 8 goes into 8 once. (8 times 1= 8) so you'd put 1 on top of 8.

Now down below you'd put 32 below 32 since you subtract it.

I'm not sure what the 3 bottom ones are.

I think you'd put 8 in the first boxes then 0 cause 8=8 = 0.

good luck <3

Answer:

Step-by-step explanation:

1. Look at the first digit and ask yourself: is this divisible by 8? (3 is not so you look at the next one)

2. 8 goes into 32 evenly 4 times (put 4 at the top)

3. Subtract 42

4. Drag down the 8

5. Does 8 go into 8? (Yes!)

6. Put one at the top and subtract to get zero

7. Answer is at the top: 41

Given two triangles with three corresponding angles that are congruent, why can't the two triangles be proved congruent? A) Give

Xelga [282]

The answer is the triangles could have the same shape( that is all the angles are equal) but the sides may not be the same length . Thay are similar but not necessarily congruent.

C is the correct choice.

How many ml of a 20% acid mixture and a 80% acid mixture should be mixed to get 120ml of a 35% acid mixture?

shutvik [7]

Answer:

Volume of Mixture A =90 ml

Volume of Mixture B =30 ml

Step-by-step explanation:

Let say, Mixture A + Mixture B = Mixture C

Volume of Mixture A is x

Volume of Mixture B is y

So, Volume of Mixture C is x+y = 120 ml

Now, Acid contain in Mixture A is 20% =0.2x

Acid contain in Mixture B is 80% =0.8y

Also, Acid contain in Mixture C is 35% =(0.35)(x+y) = 0.35×120=42

Now, we know that,

Acid contain of Mixture A + Acid contain of Mixture B=Acid contain of Mixture C

∴ 0.2x+0.8y=42

∴ 2x+8y=420

We get two linear equations

2x+8y=420 and x+y = 120

Solving above equation...

∴ x=120-y

Replacing x value in 2x+8y=420

∴ 2(120-y)+8y=420

∴ 240-2y+8y=420

∴ 6y=180

∴ y=30

Replacing y value in any equation

∴ x=120-y=120-30=90

∴ x=90

Thus,

Volume of Mixture A is x=90 ml

Volume of Mixture B is y=30 ml

f(x) = x4 - 50x2 + 3 (a) Find the intervals on which f is increasing. (Enter the interval that contains smaller numbers first.)

shtirl [24]

Answer:

(-5, 0) ∪ (5, ∞)

Step-by-step explanation:

I find a graph convenient for this purpose. (See below)

When you want to find where a function is increasing or decreasing, you want to look at the sign of the derivative. Here, the derivative is ...

f'(x) = 4x^3 -100x = 4x(x^2 -25) = 4x(x +5)(x -5)

This has zeros at x=-5, x=0, and x=5. The sign of the derivative will be positive when 0 or 2 factors have negative signs. The signs change at the zeros. So, the intervals of f' having a positive sign are (-5, 0) and (5, ∞).

The sum of two consecutive integers is -15. Which equation could you use to find the two integers and what is the smaller intege

PtichkaEL [24]

Answer:

-8

Step-by-step explanation:

x+x+1= -15

2x+1=-15 (group the x's together)

2x= -14 (move the 1 to the right side)

x= -7

(-7)+(-8) = -15

-8 is the smaller integer
