write a multiplication problem using two decimals that has a product greater than 0.1 but less than 0.2

wariber [46]

So the question is asking to write a multiplication problem that uses two decimals that has a product greater than 0.1 but less than 0.2 and in my further computation, I would give an example of 0.5*1.5 equals 0.75. I hope you are satisfied with my answer and feel free to ask for more

Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it

ArbitrLikvidat [17]

Answer:

(8 / x) + (21 / y)

Step-by-step explanation:

Given that:

Average driving speed = x mph

Miles driven to work = 8 mile

Miles by train to work = 21 miles

Average train speed = y

Total time taken to get to work. :

Recall : time taken = distance / speed

Hence,

Time taken =) total distance / average driving speed)

Total time taken = (8 / x) + (21 / y) hours

Total time taken = (8 / x) + (21 / y) hours

Answer:

The approximate perimeter of △ABC is 12.34 units

Step-by-step explanation:

we know that

The perimeter of a triangle is the sum of its three length sides

so

$P=AB+BC+AC$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

step 1

Find the distance AB

we have

A(3,4), B(−1,1)

substitute the values

$d=\sqrt{(1-4)^{2}+(-1-3)^{2}}$

$d=\sqrt{(-3)^{2}+(-4)^{2}}$

$d=\sqrt{25}$

$d_A_B=5\ units$

step 2

Find the distance BC

we have

B(−1,1),C(−2,5)

substitute the values

$d=\sqrt{(5-1)^{2}+(-2+1)^{2}}$

$d=\sqrt{(4)^{2}+(-1)^{2}}$

$d=\sqrt{5}$

$d_B_C=2.24\ units$

step 3

Find the distance AC

we have

A(3,4),C(−2,5)

substitute the values

$d=\sqrt{(5-4)^{2}+(-2-3)^{2}}$

$d=\sqrt{(1)^{2}+(-5)^{2}}$

$d=\sqrt{26}$

$d_A_C=5.10\ units$

step 4

Find the perimeter

$P=5+2.24+5.10=12.34\ units$
