Maria is planting a row of flowers in a bed 28 feet long. The instructions say to space the plants 1 foot apart, allowing room for 28 flowers. The flowers come in flats containing 6 plants per flat.
How many flats will she need?
How many plants will she have left over?

Answers

Answer:

She will need 5 flats.

She will have 2 plants left over.

Step-by-step explanation:

Since she needs 28 flowers and there are 6 flowers in each plant.

To find the number of flats she needs simply divide 28 by 6

=28/6

=4.67

=Rounding off we get 5

Now we know that she need 5 flats so 5 flats will contain 5*6= 30 flowers total.

Since she has space for 28 flowers only the remainder will be;

30-28=2

Therefore she will have 2 plants leftover.

Answer:

arc BC = 60°m∠ADC = 60°m∠AEB = 105°m∠ADP = 45°m∠P = 60°

Step-by-step explanation:

The sum of arcs of a circle is 360°. The given conditions tell us arc BC ≅ arc AB, so the four arcs of the circle have ratios ...

  CB : BA : AD : DC = 2 : 2 : 3 : 5

The sum of ratio units is 2+2+3+5 = 12, so each one stands for 360°/12 = 30°. Then the arc lengths are ...

  arc BC = arc BA = 60° . . . . 2 ratio units each

  arc AD = 90° . . . . . . . . . . . . 3 ratio units

  arc DC = 150° . . . . . . . . . . . .5 ratio units

The inscribed angles are half the measure of the intercepted arcs:

  ∠ADC = (1/2) arc AC = 1/2(120°) = 60°

  ∠ADP = 1/2 arc AD = 1/2(90°) = 45°

The angles at E are half the sum of the measures of the intercepted arcs.

  ∠AEB = (arc AB + arc CD)/2 = (60° +150°)/2 = 105°

Angle P is half the difference of the intercepted arcs.

  ∠P = (arc BD -arc AD)/2 = (210° -90°)/2 = 120°/2 = 60°

__

In summary, ...

  arc BC = 60°

  m∠ADC = 60°

  m∠AEB = 105°

  m∠ADP = 45°

  m∠P = 60°

A 40 g ball of yarn is 125 m long. What is the mass of a ball of the same yarn that is 2 km long?

Answers

Answer:

640g

Step-by-step explanation:

1000m=1km so 125m times x= 2km x is 16 so we multiply 16 by 40 to get 640 g

The mass of 2 km long yarn ball is 640.

What is mass?

A measure of how much matter is in an object. This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains a lot of matter.

Given

40 g ball of yarn is 125 m long

To find mass for 2 km = 2000 m long yarn

[tex]\frac{40}{125} \ 2000[/tex]   =   [tex]\frac{80000}{125}[/tex]    =     640g

Hence, The mass of 2 km long yarn ball is 640.
