Answer: AD = 9cm

Step-by-step explanation: This is a 30-60-90 triangle, so the hypotenuse is equal to twice the length of the short side of the right angle.

BC is the short side of the large triangle, so AB, the hypotenuse of the large triangle is 2×6, 12 cm

BC is also the hypotenuse of the small triangle, ΔBCD, so it is twice the length of BD, to that makes BD = 6/2= 3

Subtract BD from AB.

That's 12 - 3 = 9 the length of AD

Remember slope is $\dfrac{rise}{run}$ . In the graph we can just pick two points on the line to find the rise and run between. Let's say we choose (0,3) and (1,7). Between those points there is 7-3=4 rise and 1-0=1 run. So the slope is $\dfrac{4}{1}=\boxed{4}$

In the seahorse tank at an aquarium, 70% of the male seahorses

lara [203]

Part A: Kennedy's expression is incorrect because 0.07 is 7 percent, not 70.

Part B: The correct expression would be 0.7 * 20, which equals 14

Hazel is putting together charm bracelets. For each bracelet she uses

Reika [66]

<u><em>Answer:</em></u>

37/96

<u><em>Explanation</em></u>:

Hazel uses 1yd for 60 charms, so for 5/8yd she would use 5/8×60=37.5.

Because she can’t use a fraction of a charm, she would use 37 charms which is 37/96 of the charms she has.

What is 5x-4y=-7 (-20,-8)in slope intercept form

forsale [732]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following equation:

$5x-4y = -7$

We manipulate algebraically to write the equation of the slope-intersection form:

$-4y = -7-5x\\4y = 5x + 7\\y = \frac {5} {4} x + \frac {7} {4}$

We check if the given point belongs to the equation:

$y = \frac {5} {4} (- 20) + \frac {7} {4}\\y = -25 + \frac {7} {4}\\y = \frac {-100 + 7} {4}\\y = - \frac {93} {4}$

The point does not belong to the equation.

ANswer:

$y = \frac {5} {4} x + \frac {7} {4}$
