Michael takes a sip of water every 20 minutes while playing soccer. He took his first sip at 3:05. When did he take his sixth sip?

Answers

Answer:

Michael took his 6th sip at 4 : 05

Step-by-step explanation:

Duration in which Michael takes a sip of water = 20 minutes

Therefore, he will take his sixth sip after (20 × 6) = 120 minutes Or after 2 hours

If he takes first sip of water at 3 : 05

Then he will take his sixth sip at ( 3 : 05 + 2 : 00)

Time at his sixth sip = 5 : 05

how to simplify numbers

Answers

Hopes this helps:

Answer:

•ROUND IT OFF
Create zeros.
So 199 becomes 200.

•ROUND THE ORDER OF MAGNITUDE
Round a lot, to the nearest “power ten”.
So 218 comes 100, and 2,180 becomes 1,000.

•SLIDE THE DECIMAL POINT
Compact those zeros created by rounding.
So 200,000,000 becomes 2•10^8 (exponential notation).

•SUBSTITUTE A NUMBER YOU CAN REMEMBER
Instead of rounding, find a nearby number you can remember.
So 218 becomes 222, or 210 or 200, something else easy.

Answer:

Simplify means to make smaller or more simple.

Step-by-step explanation:

You need to make the number which needs to be simplified into a number lower than the original number.

For example:

"4" would simplify to "2"

beace half of 4 is 2. This could further be simplifed as "1" is half of 2.

so if there was a fraction:

4/8

the numerator would simplify to 1 and the denominator would simplify to 2 because whatever you do to the top you must do to the bottom. The numerator stops simplifying at 1 and the denominator stops simplifying at 2

so

4/8 = 1/2

A farmer harvested 1,760 pieces of fruit. 65% of them were not oranges. How many oranges did the farmer harvest?

Answers

Answer:

Number of oranges= 616

Step-by-step explanation:

Giving the following information:

A farmer harvested 1,760 pieces of fruit. 65% of them were not oranges.

To calculate the number of oranges, we need to use the following formula:

Number of oranges= total number of fruits*percentage of oranges

Number of oranges= 1,760 * (1 - 0.65)

Number of oranges= 616

Answers

Answer:

1.1     Solve   x-3y+7  = 0

recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  x-3y+7  = 0 and calculate its properties

Answer: Solution: (-4, 1)

Step-by-step explanation:

x = 3y - 7

4x + 5y = -11

Substitute x for 3y - 7

4x + 5y = -11

4 (3y - 7) + 5y = -11

12y - 28 + 5y = -11

17y - 28 = -11

Add 28 to both sides

17y = 17

y = 1

x = 3y - 7

x = 3(1) - 7

x = 3 - 7

x = -4

Solution: (-4, 1)

Answer:

  f, h, g

Step-by-step explanation:

The axis of symmetry for a vertically-opening parabola is the line ...

  x = constant

where the constant is the x-coordinate of the vertex.

__

h(x)

The equation of f(x) is given in vertex form ...

  f(x) = a(x -h)² +k . . . . . vertex: (h, k)

where (h, k) = (-4, 1).

The axis of symmetry of f(x) is x = -4.

__

g(x)

The equation of g(x) is given in standard form ...

  g(x) = ax² +bx +c

The line of symmetry for this parabola is ...

  x = -b/(2a) = -(-16)/(2(2)) = 16/4 = 4

The axis of symmetry of g(x) is x = 4.

__

h(x)

The x-coordinate of the vertex can be read from the graph:

  x = 1

The axis of symmetry of h(x) is x = 1.

__

From smallest to largest, the rank is f(x), h(x), g(x).

What is the equation of the line with a slope of 2 through (-4, 6) in point-slope form?
O y = 2x + 14
Oy-6 = 2 (x +4)
Oy= 2x – 14
Oy+6 = 2 (x – 4)

Answers

Answer:

y - 6 = 2(x + 4)

Step-by-step explanation:

Point slope form is y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex]).

[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the points that they give you in the problem, which is (-4, 6), and m is the slope, which is 2.

When you plug everything in, you should get

y - 6 = 2(x + 4).

. CDEF is a trapezium
. ABCF is a rectangle
. BD = 9cm
. AB = 6cm
. EF = 3cm
. perimeter of ABCF = 20cm

Answers

9514 1404 393

Answer:

  24 cm²

Step-by-step explanation:

To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...

  P = 2(AB +BC)

  BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm

Then CD is ...

  CD = BD -BC = 9 cm -4 cm = 5 cm

The area of the trapezium is given by the formula ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²

The area of trapezium CDEF is 24 cm².

Sarah hired a painter to paint her bedroom walls and ceiling. Each of the four bedroom walls is 18 ft. Long and 8 ft. High. Two walls each have one door, and both doors measure 3 ft. By 7 ft. One wall has a window that is 3 ft. By 5 ft. The doors and window do not have to be painted. A gallon of paint can cover 300 ft.2. A hired painter claims that he will need three gallons to paint the one room. Is the estimate correct?

Answers

Answer:

The estimate is not correct?

Step-by-step explanation:

Given data

Area of wall = 18*8

=144ft^2

=4*144

=576ft^2

Area of doors

=3*7

=21ft^2

=2*21

=42ft^2

Area of window

=3*5

=15ft^2

Hence the total surface area of the room

=576-42-15

=519ft^2

The amount of paint needed= 519/300= 1.73

Approximately 2 gallons

We are told that 1 gallon will cover 300ft^2

Hence 3 gallons will cover 300*3= 900ft^2

Therefore the painter overestimated the amount of paint needed

As 2 gallons will do the job
