can anyone pls tell me the answer to this pls

Answer:

2.  12 2/9

Step-by-step explanation:

Because of the choices, I assume the three addends are mixed numerals:

3 4/7 + 4 2/9 + 4 3/7 =

= 3 + 4 + 4 + 4/7 + 2/9 + 3/7

= 11 + 7/7 + 2/9

= 11 + 1 + 2/9

= 12 2/9

Answer: 2.  12 2/9

Answer:

32% increase at the end of 20 years

Step-by-step explanation:

If the population increases at a rate of 1.6% per year, we should multiply it by the number of years that passed, which in this case, is 20. When we multiply those, we get 32%.

It is belove sea level, so it will be between negative 2 and negative 3 on a vertical number line.

Answer:

the answer to this question is option D mark me as brainliest

Answer:

The preceding chapter explored implications of research on learning for general issues relevant to the design of effective learning environments. We now move to a more detailed exploration of teaching and learning in three disciplines: history, mathematics, and science. We chose these three areas in order to focus on the similarities and differences of disciplines that use different methods of inquiry and analysis. A major goal of our discussion is to explore the knowledge required to teach effectively in a diversity of disciplines.

Answer:

1.88 to 2 decimal places

Step-by-step explanation:

First, I plugged in 1.8 and 1.9:

1.8^3-3*1.8=0.432

1.9^3-3*1.9=1.159

Then, I plugged in 1.85:

1.85^3-3*1.85=0.78

Next, I plugged in 1.87 to get the answer closer to 1:

1.87^3-3*1.87=0.93

Finally, I plugged in 1.88 to get even closer to 1:

1.88^3-3*1.88=1.00

Hope this helps!

Answer:

Step-by-step explanation:

1.8=-0.568 is too small

1.9=0.159 is too big

1.87=-0.70797 is too small

1.88=0.004672 is too big

Next, I plugged in 1.87 to get the answer closer to 1:

1.87^3-3*1.87=0.93

Finally, I plugged in 1.88 to get even closer to 1:

1.88^3-3*1.88=1.00

1.875=-0.033203125 is too small

so it should be 1.88 to 2 decimal places

Answer:

1100 is when the two cars met

Step-by-step explanation:

the two lines intercept at 1100, 60km

Answer:

y = 3x -3

Step-by-step explanation:

Find the slope first

Givens

y2 = 3

y1 = - 3

x2 = 3

x1 = 1

Equation

m= (y2 - y1)/(x2 - x1)

Solution

m = (3 - - 3) / (3 - 1)

m = (3 + 3) / 2

m = 3

Find the y intercept next

Use either point to find the y intercept

y = 3x + b

x = 3

y = 3

y = 3*3 + b

3 = 6 + b

-3 = b

Answer

y = 3x - 3

Answer:

6

Step-by-step explanation:

So I assume it's 4 × x × 2 = 48

First multiply the like terms (4 x 2) and you'll get 8.

8 × x = 48

Then you 8 by the x and get 8x

8x = 48.

Lastly you'll just divide 48 by 8 and get 6.

Hope your brother understands how this works now! (It's basically legal cheating)

Answer:

B

Step-by-step explanation:

30x = 30 minutes per day

Answer: D

(I might be wrong btw, srry)

Step-by-step explanation:

A and C aren't possible cause they suggest mintues. In your expression 30 is already the minutes. As for B which is really similar to D, it can't be either because it was only for this one season and not all.

Have a nice day :)

Answer:

Answer:

$9.35

Step-by-step explanation:

14.86+25.88+5.76=46.5

55.85-46.5=9.35

Answer:

The rounded number would be nine

Step-by-step explanation:

It would be nine because you convert 55.85 to 56 then convert 14.86 to 15 convert 25.88 to 26 and convert 5.76 to 6 then subtract all of that to get nine hope it helps

Answer:

0.75

Step-by-step explanation:

From the attached question, we

3÷ 4

We are asked to find 3÷ 4

3 ÷ 4 = 3/4

We simplify further in other to get a decimal form

3/4 = 0.75

Answer:

b

Step-by-step explanation:

denominator(5) stays the same

multiply 2 by 4 since that is 1 fourth of an hour.

So now its 8/5

5 goes into 8 1 time with 3 leftover

So the 1 is a whole number now

the leftover fraction 3/5

=1  3/5

Answer:

22 m

Step-by-step explanation:

The computation of the how much far does the boat travel is as follows:

sin 43 degrees = 15 ÷ d

d = 15 ÷sin 43 degrees

= 15 ÷ 0.6820

= 21.99

= 22 m

Hence, the how much far does the boat travel is 22 m

We simply applied the above formula so that the correct value could come

The same is to be considered

Answer:

6. 4

7. 0

Step-by-step explanation:

6. Slope of line that passes through (-1, -4) and (1, 4):

Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - (-4))}{1 - (-1)} = \frac{8}{2} = 4 [/tex]

7. Slope of line that passes through (1, 2) and (-3, 2):

Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 2)}{-3 - 1} = \frac{0}{-4} = 0 [/tex]

Answer:

2.5 or 2 1/2 apples.

Step-by-step explanation:

5/2 simplified will be 2.5 or 2 1/2.

If you look into it further, because Richard had 15 apples, you subtract 2 1/2 apples he gave Pam which would leave him with 12.5 or 12 1/2. But really the answer is two and a half apples.

Answer:

I believe a to the 8th power

Step-by-step explanation:

when you multiple number with numbers in the power place you multiply the numbers and add the power numbers, so in the case a times a is a and -3 plus 5 is 2 or you could think of it as 5 - 3 = 2

Answer:

40

Step-by-step explanation:

SF of KP to KN = 4

If LM = 32, then we would have to divide 32 by 4 in order to get the missing length of KL.

32 ÷ 4 = 8

Length of KL = 8

Length of LM = 32

Length of KM = 32 + 8 = 40

Answer:

=4/3 or 1 and 1/3

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Let's look at the first option in this multiple-choice; 18. 18 is divisible by 18, but is not divisible by 35, so that answer isn't right.

What about 3? 3 is divisible by 18, but it isn't divisible by 35. Let's move on.

7 is divisible by 35, but it isn't divisible by 18.

1 is universally divisible by anything. That doesn't mean it is the greatest common factor, but in this case it is, because none of the other options are a factor of both numbers given. Therefore, 1 is divisible by 18.
