C. 13

In the circle, angle F is an inscribed angle. The arc measure of an inscribed angle is the inscribed angle times 2. So you set up the equation as;

(6x-8)2=10x+10

Distribute

12x-16=10x+10

Add 16 on both sides

12x=10x+26

Subtract 10x from both sides

2x=26

Divide 2 from both sides

X=13

Write the equation of the circle that has a center of (-7, 17) with a radius of V19.

kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at (h,k) and radius r is given by ${\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}$ . Now , using same concept in this question ;

${:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}$

${:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}$

This is the required equation of Circle

Darrin put the numbers 7.25, 7.52, 5.72 and 5.27 in order from the greatest to the least. Is his work correct? Explain.

vampirchik [111]

No his work is not correct because 5.72 is larger than 5.27. so therefore you can not be correct

Find M a)21 b)32 c)40 d)63 Step by step please

lina2011 [118]

Answer:

a) 21

Step-by-step explanation:

If the columns are labeled a, b, c, d left to right, it appears that we have ...

$\sqrt{a}\times(b-c)=d\\\\\sqrt{49}\times(10-7)=21$

The value of M is 21.

Questions like this require that you try different combinations of operations on the numbers shown to see if you can find a relationship. Here, the left column is a perfect square, so that is a clue. The difference of the numbers in the middle columns is a factor of the number in the right column -- another clue. It takes a certain amount of creative thought and familiarity with arithmetic facts. There is no "step-by-step" for a problem like this.

What is the value of x? Please show the steps

nordsb [41]

Let D be the endpoint of the angle bisector opposite A on lying on side BC. The angle bisector theorem states that the ratio of BD to CD is equal to the ratio of AB to AC. In this case, you have

$\dfrac{2x-1}{3x}=\dfrac9{15}$

(This is the same equation that you have, it's just rearranged.)

Multiply both sides by $3x$ and 15.

$15\times3x\times\dfrac{2x-1}{3x}=15\times3x\times\dfrac9{15}$
$15(2x-1)=3x\times9$

Now you can solve for $x$ .

$30x-15=27x$
$3x=15$
$x=5$

Solid A has a volume of 28 in³. The scale factor of A to B is 1:2. What is the volume of Solid B?

PilotLPTM [1.2K]

Answer: 56in³

Step-by-step explanation:

Let the volume of solid B de denoted as x. Based on the information given in the question, we can solve further by:

1/2 = 28/x

Cross multiply

1 × x = 2 × 28

x = 56

Therefore, the volume of solid is 56in³.
