Which point on the number line best represents the value of V11

Okay so our starting point is - 1,260 feet

Now it is descending (-) 5 ft per minute for 12 minutes

So we multiply -5 (negative because it is descending) by 12

-5 x 12 = -60

So now we add -60 to -1,260

This would be -1,320

So the submarine's new position in relation to the sea level is -1,320

Hope this helped. Have a great day!

that would be -1260 + 12(-5) = -1260 - 60 = -1320 feet

Answer:

x = 10 and y = 15

Step-by-step explanation:

The arrows on lines AB and CD indicate that they are parallel. This means that we have to look for Z-angles (I don't know if they are called the same where you're from but I hope you recognise the term). This means that ∠ABC = ∠BCD

5x - 20° = x + 20°

4x = 40°

x = 10°, which gives us the first answer.

The angle formed by points ACE (a straight line) is 180 degrees. Lets refer to this as angle ACE. We also know this angle consists of angle ACB, BCD and DCE. This gives us the following equation:

angle ACE = angle ACB + x + 20° + y + 20° = 180°

angle ACB + x + y + 40° = 180°

angle ACB = -x - y + 140°

Inserting the x we found earlier this gives

∠ACB = - y + 130°

Now we can find a second equation to describe ACB by looking at the triangle it is inside. The angles in a triangle always add up to 180°, giving the following expression:

4y - 25° + 5x - 20° + ∠ACB = 180°

Substituting x again gives

4y - 25° + 50° - 20° + ACB = 180°

ACB = 180 - 4y - 5° = 175° -4y

Combining the two expressions for ACB gives the final equation to solve:

175° - 4y = -y + 130°

-3y = -45

y = 15

Answer:

30 pushups

Step-by-step explanation:

25/100 = x/120

so, 120x25 = 100x

3000 = 100x

3000/100= x

x = 30

so, Lauren has completed 30 push-ups.

Answer:

7cm

Step-by-step explanation:

One side of a square is increased by 8 cm, let us say the length got increased by 8 cm. So we have length of x + 8 cm

An adjacent side, the width, decreased by 2 cm. So we have width of x - 2cm

Perimeter of rectangle = 2(length + width)

40 = 2( (x + 8) + ( x - 2) )

40 = 2( 2x + 6)

40 = 4x + 12

28 = 4x

x = 7 cm

That is 7 cm of the length of the side of the square

Answer:

(-4,5) rotated 90° Clockwise is (5,4) Counter Clockwise is (-4,-5)

Step-by-step explanation:

Counter clockwise is moving down or right Clockwise is moving left or down.

the first one 1. = 1

the second one 2. = 1

Answer:

A) 1

B) [tex]\frac{2}{1}[/tex], or 2

Explanation:

In a fraction, when both the numerator and the denominator (top and bottom numbers) are the same, the fraction is equal to one. If the numerator (top #) is larger than the denominator (bottom #), then the answer will be larger then 1.

If the numerator is exactly twice the denominator then the answer is 2

Answer:

Other side = 60

Perimeter = 150

Step-by-step explanation:

Using Hypothenuse formula

25²+B²=65²

625+B²=4225

B²=4225-425

B²=3600 (Bring Square to the other side to become Square root)

B=√(3600)

B=60

Perimeter:(Sum of all side)

60+65+25

Answer:

I think it's 4/9 the first one

Answer:  y=5

Step-by-step explanation:

The line only has a value of 5, regardless of the value of x.  So the slope of this line is "o," the vlaue of x has no influence on the value of y.

y = mx + b

y = ox + b

b is the y-intercept, the value of y when x = 0.  That would be 5, again:

y = 0x + b

y = b

y = 5

Answer:

x = 5

Step-by-step explanation:

(5) + 20/2 = 3(5)

Answer:

 (B)  4

Step-by-step explanation:

Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...

  3 + 8 = 11

This tells you A = 8, so the top number is 1983, and the middle number is B78.

Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...

  1 + 9 + B = <something ending in 4>

We know the something cannot be 04 or 24, so must be 14. Then ...

  10 + B = 14   ⇒   B = 4

__

So, the whole sum is ...

  1983 +478 = 2461

and the letter values are ...

Answer:

B is 4.

Step-by-step explanation:

If we start by the ones place and add we know that to get a one the total must be 11. 11-3 = 8.  Therefore A = 8.

Now we move to the tens place, since we know A is 8 we can substitute it there.  Don't forget to add the one from the 11 we got. 1+8+7 = 16

Now we move to the hundreds place and we carry our one from 16 so now it's 1 + 9 + ? = 4, if we know that our total needs to be 14 in order to have the 4 there- 1 + 9 is 10 we can do 10 + 4 and that gets us 14. So B is 4.
