On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w
netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

\frac{1}{2} \times 100 = 50

Add both skateboarding and walking

30\% + 50\%\\\\= 30 + 50\\\\= 80

Now, subtract that from a whole percent

100 - 80 = 20\\\\20\%

Convert it to a decimal

20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

A G.P is such that the 3rd term minus a first term is 48. The 4th term minus 2nd term 144. Find: (i) Common ratio ii) The first
EleoNora [17]

Answer:

Step-by-step explanation:

r is the common ratio.

Third term minus first term is 48.

a₃ - a₁ = 48

a₃ = a₁r²

a₁r² - a₁ = 48

a₁(r²-1) = 48

r²-1 = 48/a₁

Fourth term minus second term is 144.

a₄ - a₂ = 144

a₂ = a₁r

a₄ = a₁r³

a₁r³ - a₁r = 144

a₁r(r²-1) = 144

r²-1 = 144/(a₁r)

48/a₁ = 144/(a₁r)

r = 3

:::::

r²-1 = 48/a₁

a₁ = 6

:::::

a₆ = a₁r⁵ = 1458

The lines whose equations are 2x + 3y = 4 and y = mx + 6 will be perpendicular when
Natalka [10]

Answer:

These lines will be perpendicular when m =  ³⁄₂

Step-by-step explanation:

Two lines are perpendicular when the product of their gradients equal to -1. So:

m₁ * m₂ = -1

Let's get the first equation in gradient-intercept form (same as equation two).

2x + 3y = 4

3y = -2x + 4

y = -⅔x + ⁴⁄₃

We know the first gradient, and now we can find the gradient of the second line (which when multiplied will result in -1 as these lines are perpendicular). So:

-⅔ * m₂ = -1

m₂ =  ³⁄₂
