Answer:

The answers are given in step-by-step explanation

Step-by-step explanation:

In question 4,

Elina walked 12 miles then she walked 0.25 that distance.

We have to find the distance she walked

Distance=12+0.25 of that distance

              = 12+0.25(12)

              = 12(1+0.25)=12\times 1.25=15 miles

Hence, A, B, and C are correct

In question 5,

Given circumference is 600 m

we have to find the good approximation area of circle

circumference = 600 m

2\pi \times r=600

\pi \times r=300 ⇒ r=95.49

Area of circle is \pi \times r^2

                       = (3.14)(95.49)^2=28631.587914m^2

Hence, the good approximation area of circle is 30,000 m^2

In question 6,

Given d=3t where d represents the distance between the snail and rock in inches and t represents the time in minutes.

Number 3 represents that distance between snail and certain rock is 3 times that of time.

given distance is 9 inches we have to find the time i.e d=3t ⇒ 9=3t ⇒ t=3 minutes.

Hence, will be 3 minutes when snail is 9 inches far from certain rock.

Now, times given 9 minutes we have to find the distance, d=3t=3(9)=27 inches.

Schach [20]

Answer:

Average speed   is 37.35 mi/h

Step-by-step explanation:

given data

leave =  34 minutes before

church distance =  12.0 miles

average speed first 17 minutes =  5.0 mi/h

solution

so we find Total distance travel in first 17 minutes = speed × time

Total distance travel in first 17 minutes = 5 × \frac{17}{60}

Total distance travel in first 17 minutes = 1.416 mi

and

Distance Remaining = 12 - 1.416 = 10.584 mi

Time Remaining = 34 - 17 min = 17 min

so

remaining distance Average speed  = \frac{distance}{time}

Average speed  = \frac{10.584}{\frac{17}{60}}

Average speed   is 37.35 mi/h

Easy maths question I’ll give brainiest
NISA [10]

Answer:

BC ≈ 12.6 m

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan31° = \frac{opposite}{adjacent} = \frac{AB}{BC} = \frac{7.6}{BC} ( multiply both sides by BC )

BC × tan31° = 7.6 ( divide both sides by tan31° )

BC = \frac{7.6}{tan31} ≈ 12.6 m ( to 3 sf )
