Andrew [12]

The Inequality representing money she can still spend on her friend birthday gift is .

Jordan can still spend at most $30 on her friends birthday gift.

Step-by-step explanation:

Given:

Total money need to spend at most = $45

Money spent on Yoga ball = $15

We need to find how much money she can still spend on her friend birthday gift.

Solution:

Let the money she can still spend on her friend birthday gift be 'x'.

So we can say that;

Money spent on Yoga ball plus money she can still spend on her friend birthday gift should be less than or equal to Total money need to spend.

framing in equation form we get;

The Inequality representing money she can still spend on her friend birthday gift is .

On solving the the above Inequality we get;

we will subtract both side by 15 using subtraction property of Inequality.

Hence Jordan can still spend at most $30 on her friends birthday gift.

Write the equation in standard form for the circle that has a diameter with endpoints (6, -9)
nevsk [136]

Answer:

Step-by-step explanation:

By definition a diameter goes through the center of the circle.  So if we find the midpoint of the diameter, we will have the h and k of the center.  Then we will use one of the points ON the circle as x and y and solve for r.  Here goes:

M=(\frac{6+(-6)}{2},\frac{-9+(-9)}{2}) to get a midpoint/center of (0, -9).

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2

Filling in with h, k, x, and y:

(6-0)^2+(-9-(-9))^2=r^2 which simplifies to

6^2+0^2=r^2  so

r^2=36

Now we can write the equation of the circle:

x^2+(y+9)^2=36

I need about 2 of these but pls explain so I can learn and try on my own pls
GuDViN [60]

These problems are based on the Pythagorean Theorem. The Pythagorean Theorem is a^2 + b^2 = c^2. If the two sides are equal, the triangle is a right triangle. If c^2 is less, the triangle is acute. If c^2 is more, the triangle is obtuse.

Obtuse: c^2 > a^2 + b^2

Acute: c^2 < a^2 + b^2

Right: c^2 = a^2 + b^2

#7 --- Obtuse

21^2 ___ 8^2 + 15^2

441 ___ 64 + 225

441 > 289

#8 --- Right

20^2 ___ 12^2 + 16^2

400 ___ 144 + 256

400 = 400

#9 --- Acute

6^2 ___ 4^2 + 5^2

36 ___ 16 + 25

36 < 41

Hope this helps!
