So 45 in 30mins

we ususlly want to make the smallest number equal to one or as close to one as possible so
45/30=3/3 times 15/10
3/3=1
1 times 15/10=15/10
15/10=5/5 times 3/2
5/5=1
1 times 3/2=3/2
3 divided by 2 is 1.5
1.5 flowers per minute

Answer:

Distance LM = 5.20 unit (Approx.)

Step-by-step explanation:

Given coordinates;

L(1, 4, 7) and M(2, 9, 8)

Find:

Distance LM

Computation:

Distance between three-dimensional plane = √(x2 - x1)² + (y2 - y1)² + (z2 - z1)²

Distance LM = √(2 - 1)² + (9 - 4)² + (8 - 7)²

Distance LM = √(1)² + (5)² + (1)²

Distance LM = √1 + 25 + 1

Distance LM = √27

Distance LM = 3√3 unit

Distance LM = 3(1.732)

Distance LM = 5.196

Distance LM = 5.20 unit (Approx.)

Help help help math please last one be honest
nadya68 [22]

Answer:

122 degrees

Step-by-step explanation:

The two intersecting lines are parallel for this problem, which means that the angle next to angle3 is the same degree measure as the one that is 58 degrees.

Also, remember that two angles next to each other on a straight line are supplementary, meaning that they add to 180 degrees.

When keeping these two things in mind, you can solve like this:

180 = angle3 + 58

180 - 58 = angle3

angle3 = 122

122 degrees

How to solve if 5a=6 and 7b=8, 35ab= <br> (please explain, i need explaination)
ser-zykov [4K]

Answer:

35ab = 48

Step-by-step explanation:

given

5a = 6 ( divide both sides by 5 )

a = \frac{6}{5}

and

7b = 8 ( divide both sides by 7 )

b = \frac{8}{7}

substitute these values for a and b into the expression and simplify

35ab

= 35 × \frac{6}{5} × \frac{8}{7} ( divide 35 and 5 by 5 )

= 7 × 6 × \frac{8}{7}

= 42 × \frac{8}{7} ( divide 42 and 7 by 7 )

= 6 × 8

= 48
