Denver gets 5/19 of the dog food.

natka813 [3]

Answer:

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

Step-by-step explanation:

If Denver gets $\frac{5}{19}$ of the dog food, then Engle and Fido share $\frac{14}{19}$ of the dog food. If Fido have $x$ of the dog food, then Engle have $\frac{4}{3}\cdot x$ such that:

$x + \frac{4}{3}\cdot x = \frac{14}{19}$

$\frac{5}{3}\cdot x = \frac{14}{19}$

$x = \frac{42}{95}$

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

A certain forest covers an area of 2900 km. Suppose that each year this area decreases by 8.5%. What will the area be after 8 ye

Ann [662]

Answer:

1425 square kilometer.

Step-by-step explanation:

2900 - 8.5% = 2653.5

2653.5 - 8.5% = 2427.9525

2427.9525 - 8.5% = 2221.5765375

2221.5765375 - 8.5% = 2032.74253181

2032.74253181 - 8.5% = 1859.95941661

1859.95941661 - 8.5% = 1701.8628662

1701.8628662 - 8.5% = 1557.20452257

1557.20452257 - 8.5% =1 424.84213815 ≈ 1425

Mamont248 [21]

Answer:

<h2>18mins</h2>

Step-by-step explanation:

This problem is on combined work rate

given that

Marta can vacuum the house in 30 min

then her rate= 1/30

Also, her daughter will take 45 min to vacuum the house

her daughter's rate will be = 1/45

then the combined work rate is

1/30+1/45=1/T

30+45/30*45=1/T

75/1350= 1/T

1/18=1/T

This means that they will both take 18 minutes working together to vacum a house

3. Find two possible lengths for CD if C, D, and E

Kaylis [27]

Given :

C, D, and E are col-linear, CE = 15.8 centimetres, and DE= 3.5 centimetres.

To Find :

Two possible lengths for CD.

Solution :

Their are two cases :

1)

When D is in between C and E .

. . .

C D E

Here, CD = CE - DE

CD = 15.8 - 3.5 cm

CD = 12.3 cm

2)

When E is in between D and C.

. . .

D E C

Here, CD = CE + DE

CD = 15.8 + 3.5 cm

CD = 19.3 cm

Hence, this is the required solution.
