2×3×4=24

Step-by-step explanation:

2×3=6----> 6×4=24

How can I help you with the last two blanks after the 24?

Answer:

2 x 3 x 4 = 24

24 = 24 True

Step-by-step explanation:

I used a calculator :)

Answer:

add 3 to 3 getting 6 put that over 1 then distribute. 6/1(x+1/3=3)

6x + 2 = 18

now subtract both sides by 2

6x = 16

and divide

x= 16/6

simply by diving by 2

x = 8/3

Answer:

-5 is the y intercept.

Step-by-step explanation:

Ok, lets do the steps in order.

1) Make a point-slope form equation.

We know that the format of it is y - y1 = slope(x - x1), so we know have to substitute our information in the equation.

y - 5 = 5(x - 2)

2) Convert our point-slope form equation into slope intercept form, and solve for the y-intercept.

y = slope(x) + b... right? So we now have to do math.

Distribute the right side of the equation to get :

y - 5 = 5x - 10

Now cancel out the -5, and then subtract on both sides.

y = 5x - 5

And -5 is your y intercept :)

The straight road crosses the boundaries of the range of the ambulance service at two points

The length of the road that lies within the range of the ambulance service is approximately 37.95

Reason:

The function that represents the ambulance circular service area is x² + y² = 400

The equation that represents the straight road,  y = 3·x + 20

Required:

Length of the road that lies within the range of he ambulance

Solution:

The length of the road is given by the distance between the intersection

points of the road and the ambulance service region as follows;

At the intercepts, we have;

The x, and y-values of the line and the circle are equal, therefore, we have;

At the intercept, y = 3·x + 20, which gives;

x² + y² = 400

x² + (3·x + 20)² = 400

x² + 9·x² + 120·x + 400 = 400

10·x² + 120·x + 400 - 400 = 0

10·x² + 120·x = 0

x² + 12·x = 0

x² + 12·x = x·(x + 12) = 0

When x = 0, y = 3×0 + 20 = 20

When x = -12, y = 3×(-12) + 20 = -16

The intersection points of the line and the circle are;

The length of the segment AB, d, is given as follows;

The length of the road that lies within the range of the ambulance service, d, given to the nearest hundredth = 12·√(10) ≈ 37.95

The largest possible value we can make using subtraction and addition from the given numbers -5, 9, -2, 11, and -4 is 31.

A mathematical operation that represents combining objects into a larger collection is called addition.

It is denoted by the plus sign (+).

A mathematical operation that represents the process of finding the difference between numbers is called subtraction.

It is denoted by the minus sign (-).

We have,

-5, 9, -2, 11, and -4

The largest possible value we can get is by using sign multiplication.

[ Negative x Negative = Positive ]

We will use addition and subtraction wherever necessary to make all the numbers positive.

= 9 - ( -5 ) - ( -2 ) + 11 - ( -4 )

= 9 + 5 + 2 + 11 + 4

= 31

Thus the largest possible value we can make using subtraction and addition from the given numbers is 31.

Explanation:

When reflecting over the line y = x, we swap the locations of the x and y coordinates. For example, the point (5,7) becomes (7,5)

This means we have the following reflections

This operation is commonly done when determining the inverse of a graph. This is because the inverse basically undoes everything the original function applies. So this "backwards" nature of things means that x becomes y and vice versa.

Answer:

Ashely had 30 kisses! Muah!

Step-by-step explanation:

Ratio of Ashely to Keely is 5 : 2 and we know Keely had 12. Keely represents the 2 in this ratio, and how do we get from 2 to 12? We multiply by 6. We have to multiply by 6 on the other side too then. 5 times 6 is 30, so Ashely had 30 hershey kisses.

In real life, not in ratio form, Ashely had 30 kisses and Keely had 12.

Answer:

  a) 191 yards

  b) 40 yards

  c) 1.5 minutes

Step-by-step explanation:

Given:

  ΔPQR is a right triangle with the right angle at Q

  PQ = 40 yards; QR = 70 yards

  M is the midpoint of PR

  jogging rate is 150 yd/min

Find:

  a) the perimeter of ΔPQR to the nearest yard

  b) QM to the nearest yard

  c) the time to jog the path PQMRQP to the nearest tenth minute

Solution:

a) The length of PR can be found from the Pythagorean theorem:

  PR² = PQ² +QR²

  PR² = 40² +70² = 6500

  PR = √6500 ≈ 80.62 . . . . yards

Then the perimeter is ...

  perimeter = PQ +QR +PR = 40 +70 +80.62 ≈ 191 yards

__

b) Segment QM divides triangle PQR into two isosceles triangles: PMQ and RMQ. The lengths MP, MQ, and MR are all equal to half the length of PR.

  QM = PR/2 = (80.62 yd)/2 = 40.31 yd

  QM ≈ 40 yd

__

c) The segments of path PQMRQP can be grouped to simplify the computation of the path length

  PQMRQP = PQ +QM +MR +RQ +QP = PQ +(PQ +QR +(QM +MR))

Since QM +MR = PR, the length in the outer parentheses is the perimeter of the triangle. Then the jogger's total path length is ...

  PQ + perimeter(ΔPQR) = 40 yd +191 yd = 231 yd

The time it takes to jog that path is ...

  time = distance/speed

  time = 231 yd/(150 yd/min) = 1.54 min ≈ 1.5 min

It takes about 1.5 minutes.
