Answer:

<em>9. </em><em>€ 29.00</em>

<em>1</em><em>0</em><em>.</em><em> </em><em>$ 15.3</em>

<em>1</em><em>1</em><em>.</em><em>total meters = 6 timbers × 3.9 m</em>

<em>total meters = 6 timbers × 3.9 m = 23. 4 meters</em>

<em>total meters = 6 timbers × 3.9 m = 23. 4 metersextra meter he needs = (25 - 23.4) m</em>

<em>total meters = 6 timbers × 3.9 m = 23. 4 metersextra meter he needs = (25 - 23.4) m = 1.6 m</em>

<em>1</em><em>2</em><em>.</em><em> </em><em> </em>

<em>a</em><em>. Total mass of pies, 5700 × 0.26kg = 1,482kg</em>

<em>b. Total mass of pasties , 3600× 0.26kg = 936kg</em>

<em>c. total mass of pies and pasties =( 3600× 0.26+ 5700× 0.26) kg = 2418</em><em>k</em><em>g</em>

<em>d</em><em>.</em><em> </em><em>the number of heated vans = 2418kg/500</em>

<em>the number of heated vans = 2418kg/500 = 4.836kg is almost 5 vans </em>

e.

Step-by-step explanation:

9. He needs 0.4 m³ of concrete

1 m³ concrete costs €72.50

0.4m³ = x

we represent x buy the cost of concrete he'll need since we don't know

we cross multiply,

1 m³ = 72.50

0.4 = x

x = 72.50 × 0.4

x = € 29.00

10. 1 meter of hose = $ 3. 40

4.5 meter of hose = x

we cross multiply,

X= $ 15.3

11. 6 timbers, each has 3.9 m long

total meters = 6 timbers × 3.9 m

= 23. 4 meters

extra meter he needs = (25 - 23.4) m

= 1.6 m

12. 5700 pies, each has mass of 0.26kg

3600 pasties, each had mass of 0.26kg

a. Total mass of pies, 5700 × 0.26kg = 1,482kg

b. Total mass of pasties , 3600× 0.26kg = 936kg

c. total mass of pies and pasties

=( 3600× 0.26+ 5700× 0.26) kg

= 2418kg

d. the total mass of the pies and pasties is 2418kg

each heated van weighs 500kg

the number of heated vans = 2418kg/500

= 4.836kg is almost 5 vans

Instead of having 1.5 times as many pink flowers as white
elena55 [62]

Answer:

The first row has 4 pink flowers and 2 white flowers

The second row has 6 pink flowers and 3 white flowers

The third row has 8 pink flowers and 4 white flowers.

Step-by-step explanation:

Based on the above question,

Molly has decided to plant a garden with twice as

many pink flowers as white flowers per row.

We can find the number of white flowers in each row by using the principle of ratio to solve this question.

Mathematically, what Molly planted is expressed as:

2 pink flowers : 1 white flower

Therefore for the three rows:

a. The first row is 4 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

4 pink flowers = designated as y

We cross multiply

2× y = 4 × 1

Divide both sides by 2

y = 4 ÷ 2

y = 2 white flowers.

Therefore, the first row that Molly planted 4 pink flowers has 2 white flowers.

b. The second row, Molly planted 6 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

6 pink flowers = designated as z

We cross multiply

2× z = 6 × 1

Divide both sides by 2

z = 6 ÷ 2

z = 3 white flowers.

Therefore, the second row that Molly planted 6 pink flowers has 3 white flowers.

c. The third row , Molly planted 8 pink flowers

Since, 2 pink flowers : 1 white flower

2 pink flowers = 1 white flower

8 pink flowers = designated as p

We cross multiply

2× p = 4 × 1

Divide both sides by 2

P = 8 ÷ 2

y = 4 white flowers.

Therefore, the third row that Molly planted 8 pink flowers has 4 white flowers.

Therefore, since Molly has decided to plant a garden with twice as

many pink flowers as white flowers per row,

The first row has 4 pink flowers and 2 white flowers

The second row has 6 pink flowers and 3 white flowers

The third row has 8 pink flowers and 4 white flowers.

A typical middle-income household in 1980 earned $34,757. A similar household in 2009 earned $38,550. What was the relative incr
S_A_V [24]

Given conditions are :

In 1980's, a typical middle-income household earned=  $34,757

In 2009, a similar middle-income household earned= $38,550

And we have to find relative increase in income for these households from 1980 to 2009.

So first we will find the total increase in amounts.

38550-34757=3793

Relative increase = \frac{3793}{34757}*100

= 10.91% or rounding it off we get approx 11%.

Hence, the answer is 11%.
