A coral reef grows

1 answer:

3 0

If a coral reef grows at a steady rate every week, then to find how much it grows in 12 weeks, we need to multiply the growth rate by 12 weeks. Also, since we want our answer in centimeters, we can change the growth rate to centimeters. 0.15m = 15cm

15cm * 12 = 180cm

The coral reef will grow 180cm in 12 weeks.

The original blueprint of a concrete patio has a scale ofmath2inches=3feet. Victoria wants to make a new blueprint of the patio

DedPeter [7]

Complete question :

the original blueprint of a concrete patio has a scale of 2 inches=3 feet. victoria wants to make a new blueprint of the patio with a length of 16.8 inches. original blueprints length is 14 inches and original blueprints width is 12 inches. what is the scale for the new blueprint and what is the width of the blueprint with the new scale?

Answer:

2.5 fts, 14.4 fts

Step-by-step explanation:

Given that:

Scale of original blueprint : 2inches = 3 feets

To make a new blueprint with a length of 16.8 inches, the scale for the new blueprint will be :

Original scale : 2 inches = 3 feets

Original blueprint length = 14 inches

Then,

2 inches = 3 feets

14 inches = d

Cross multiply :

2d = 42

d = 21 feets

Hence, new scale for blueprint :

16.8 inches = 21 feets

2 inches = d

16.8d = 42

d = 2. 5 feets

For the width :

14 inches = 16.8 feets

12 inches = w

14w = 201.6

w = 201.6/14

Width = 14.4feets

The sum of the length of any two sides of a triangle is greater than the length of the third side. And the abc, bc=4 and ac= 8-a

alisha [4.7K]

Answer:

ab<6 units

Step-by-step explanation:

One of the basic property of any triangle is that the sum of the length of any two sides of a triangle is always greater than the length of the third side.

Here we are given a triangle abc, in whicn bc=4

ac= 8-ab

If have to make some conclusion about ab.

As per the property discussed above

ab<ac+bc

ab<8-ab+4

2ab<12

ab<6

Hence the length of ab must be less than 6 units

Evaluate log3^8, given log3^2 is equivalent to 0.631

elixir [45]

We will use the followin property of logarithms:

$log(a^b) = b log(a)$

So, we have

$log(3^2) = 2 log(3) = 0.631$

If you multiply both sides by 4, you get

$8log(3) = log(3^8) = 2.524$
