[tex] \color{plum}\bold{(C)} [/tex] Diameter of circle P is the same length as the radius of circle Q.

Given :

Diameter of circle P = 26 cm

Radius of circle P :

[tex] =\tt \frac{diameter}{2} [/tex]

[tex] = \tt \frac{26}{2} [/tex]

[tex]\color{plum} = \tt13 \: cm[/tex]

Thus, radius of circle P = 13 cm

Diameter of circle Q = 52 cm

Radius of circle Q :

[tex] = \tt \frac{diameter}{2} [/tex]

[tex] =\tt \frac{52}{2} [/tex]

[tex] \color{plum}= \tt26 \: cm[/tex]

Thus, radius of circle Q = 26 cm

Radius of circle R = 52 cm

Diameter of circle R :

[tex] =\tt radius \times 2[/tex]

[tex] =\tt 52 \times 2[/tex]

[tex]\color{plum} = \tt104 \: cm[/tex]

Thus, the diameter of circle R = 104 cm

☆ Conclusion :

▪︎Diameter of circle P is the same length as the radius of circle Q.

Therefore, the correct option is (C) Diameter of circle P is the same length as the radius of circle Q.

Answer:

x=18

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

You should draw a picture to let everything fall into place:

.................2x.......................

N ----x+7------ O ---10---- P

Then you can easily see that

x+7 + 10 = 2x

17 = 2x - x

so x = 17

NP = 2x = 2*17 = 34

NO = x+7 = 17+7 = 24

OP = 10

NO + OP = 24 + 10 = 34 = NP

Step-by-step explanation:

A certain number of nickels, dimes and quarters have a value of $5.60 there are an equal number of each type of coin. How much coins are there?

(0.05+0.10+0.25)c =5.60

0.40c=5.60

40c=560

c = 14

There are 14 nickels ,dimes and quarters.

Step-by-step explanation:

Answer:

Greg has 180 songs on his computer

Raj has 426 songs on his computer

Mark has 720 songs on his computer

Step-by-step explanation:

First you find out how much songs Greg has. He has 1/4 as many as mark so 720 x 1/4 = 180. This is because 720 x 1/4 is the same as 720/4. Now we know that Greg has 180 songs on his computer. Next, Raj has 60% of the songs Mark has so 60% of 720 is 432. Because he has 6 fewer than 60%, 432-6=426.

Therefore,

Greg has 180 songs on his computer

Raj has 426 songs on his computer

Mark has 720 songs on his computer

The measure of arcDF from the figure shown is 30 degrees

Based on the symmetry of the figure given, we can say that the measure of<DEF is equal to the minor arc DF

Given the following parameters

m∠DEF=30 degrees

Since m∠DEF =  arcDF, hence the measure of arc DF is 30degrees

The measure of arcDF from the figure shown is 30 degrees

So, let the diameter of this circle be x.

Which means :

[tex] =\tt2 \times \pi \times r[/tex]

[tex] =\tt 2 \times x \times \pi = 12\pi[/tex]

[tex] =\tt 2x\pi = 12\pi[/tex]

[tex] =\tt x = \frac{12}{2} [/tex]

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎Therefore, the correct option is (B)

Answer:

Her garden is 147 square feet.

Answer:

[tex]a_{n} = 11 - 5n[/tex]

Step-by-step explanation:

use the formula

[tex]a_{n} = a_{1} + (n - 1)d[/tex]

-14 = 6 + (5 - 1)d

-14 = 6 + 4d

-20 = 4d

d = -5

[tex]a_{n} = 6 + (n - 1)(-5) = 6 - 5n + 5 = 11 - 5n[/tex]

Answer:

Pythagorean theorem: a^2 + b^2 = c^2, a and b are the sides, c is the hypotenuse (longest side).

27^2 + 25^2 = x^2

Solving for x, we see that it is approximately 36.8.

Answer: Each pair of gloves costs $15 and each pair of hat costs $10.

Step-by-step explanation:

Let x = Cost per pair of gloves

y= Cost per hat.

As per given, we have

[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]

Multiply (ii) by 2 , we get

[tex]8x+2y=140\ \ \ \ (iv)[/tex]

Eliminate (i) from (iv), we get

[tex]3x=45\\x=15[/tex]

Put this in (ii), we get

[tex]4(15)+y=70\\60+y=70\\y=10[/tex]

Hence, each pair of gloves costs $15 and each pair of hat costs $10.

Answer:

Option 3, 18.0

Step-by-step explanation:

To find the Hypotenuse of a right triangle, use the Pythagoras theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

(see image below)

(the longest side of any right △ is always C)

In this equation, we know A is 10 and B is 15, so plug in these numbers and solve for C

[tex]10^{2} +15^{2} =c^{2}[/tex]

[tex]100 + 225 =c^{2}[/tex]

[tex]325 = c^{2}[/tex]

Now that the equation is simplified, we find the square root of 325 to solve for C.

[tex]\sqrt{325 = c^{2}}[/tex]

[tex]18.0 = c[/tex]

The final answer is C = 18.0

Hope this helps you understand :)
