Answer:
2 because the equation can be reduced to: 8.0 x 10^4.

Answer:
Actually it's 5 because there is no decimal space and if you only include 8 then that means the number is actually 8.

A= π r^2, and we don't know r, so we'll have to use r = √C/π.

√C is and infinite number, and the square root of

π is an infinite number, so this problem is impossible.

the person covers different distances at different speeds

to find the average speed we have to find the total distance travelled and the total time taken

average speed = total distance travelled / total time taken

first 200 miles

speed - 50 mph

time taken for 50 miles - 1 hour

then time for 200 miles - 1/50 x 200 = 4 hours

last 100 miles

speed - 40 mph

time taken for 40 miles - 1 hour

time for 100 miles - 1/40 x 100 = 2.5 hours

total time taken for a distance of 300 miles - 2.5 + 4 = 6.5 hours

average speed = 300 miles / 6.5 hours = 46.2 mph

average speed is 46.2 mph

Answer:

C) 7

===========================================

Work Shown:

Use the slope formula

m = (y2-y1)/(x2-x1)

Plug in the given slope we want m = -5/3 and also the coordinates of the points. Then isolate r

m = (y2-y1)/(x2-x1)

-5/3 = (2-r)/(r-4)

-5(r-4) = 3(2-r) .... cross multiplying

-5r+20 = 6-3r

-5r+20+5r = 6-3r+5r .... adding 5 to both sides

20 = 6+2r

20-6 = 6+2r-6 ....subtracting 6 from both sides

14 = 2r

2r = 14

2r/2 = 14/2 .... dividing both sides by 2

r = 7

The slope of the line through (4,7) and (7,2) should be -5/3, let's check that

m = (y2-y1)/(x2-x1)

m = (2-7)/(7-4)

m = -5/3

The answer is confirmed

**Answer:**

C) 7

Correct answer

**Step-by-step explanation:**

6x - 1/5 = 3

Do the inverse operation.

6x - 1/5 = 3

+1/5 +1/5

6x = 3 1/5

6x/6 = 3 1/5 /6

KCF:- Keep the first fraction, change the sign, flip the second fraction.

3 1/5 divided by 6/1

3*5 +1 = 15+1 =16

16/5 * 1/6

16*1 = 16

5*6 = 30

16/30 = 16/2 and 30/2

8/15

**Final answer: x = 8/15**

Do the inverse operation.

6x - 1/5 = 3

+1/5 +1/5

6x = 3 1/5

6x/6 = 3 1/5 /6

KCF:- Keep the first fraction, change the sign, flip the second fraction.

3 1/5 divided by 6/1

3*5 +1 = 15+1 =16

16/5 * 1/6

16*1 = 16

5*6 = 30

16/30 = 16/2 and 30/2

*I would like to know how you did it too*

The **area** of the **sector** of the **circle,** to the **nearest tenth** is: B. 10.5 cm²

**Area** of the **sector **of a **circle** = ∅/360 × πr².

r = radius.

Given:

∅ = 68°

Radius (r) = 4.2 cm

Substitute

**Area** of the **sector **= 68/360 × π × 4.2²

**Area** of the **sector **= 10.5 cm²

Learn more about **area of sector** on:

Area of a circle = pi * radius^2

But we're not talking about a whole circle, but a portion of the circle.

The proportion of the area of the whole circle occupied by this sector is equal to the ratio of the created angle to the angle of a whole circle;

that may seem a bit confusing but basically:

Area of the sector = pi * radius^2 * 68/360

so...

Area = pi * (4.2)^2 * 68/360

= 10.467...

= 10.5 cm^2

7% of 120 is **8.4**

Change the percentage into a decimal by dividing it over 100:

7 / 100 = 0.07

Multiply:

0.07 × 120 = 8.4
