Answer:

7hours and 30 minutes

Step-by-step explanation:

given a car travels with a speed of 50 miles -------->1hour

x miles -------->6hours

on cross multiplying we get the value of 'x'

x = 50×6 = 300

x=300miles

Now ,

40mls------->1h

300mls------->xh

x= 300/40

x=(3/4)×10

x= 7.5hours

x= 7½hours

Yoshi reported the total area of the five great lakes on the chart above.
Katarina [22]

Answer:

60000 square miles

Step-by-step explanation:

Step 1: Great lakes beginning with consonant: Huron, Michigan, Superior

Great lakes beginning with vowel: Ontario, Erie

Step 2: Estimate the areas to nearest thousand.

Estimation of area of Huron = 23000 square miles

Estimation of area of Michigan = 22000 square miles

Estimation of area of Superior = 32000 square miles

Total area of Great lakes beginning with a consonant = 23000 + 22000 + 32000 = 77000 square miles

Estimation of area of Ontario = 7000 square miles

Estimation of area of Erie = 10000 square miles

Total area of Great lakes beginning with a vowel = 7000 + 10000 = 17000 square miles

Step 3: Difference between the total area of Great lakes beginning with a consonant and the vowel

77000 – 17000 = 60000 square miles

Which formula can be used to describe the sequence?
alexdok [17]

Answer:

f(x+1) = -3/4 × f(x)

Step-by-step explanation:

first of all, the sign of the numbers in the sequence is alternating. so, there must be a "-" involved.

that eliminates the first and third answer options.

and the absolute values of the numbers in the sequence are going down. |f(x+1)| < |f(x)|

that eliminates the fourth answer option, as this says that

|f(x)| < |f(x+1)|. and that is the opposite of how the actual sequence behaves.
