Answer:
Step-by-step explanation:
To find the center and the radius, we need to put the equation in the (x-a)^2+(y-b)^2=r^2 [a is the x-coordinate, b is the y-coordinate, and r is the radius].
(x+6)^2+(y+7)^2 - 36 - 49 + 69 = 0
(x+6)^2+(y+7)^2 - 16 = 0
(x+6)^2+(y+7)^2 = 16
(x+6)^2+(y+7)^2 = 4^2
The center is (-6,-7) and the radius is 4.

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid to vertex D is 2.5 units, as shown. Find the length of segment AD, in units.
Answers
Answer:
AD is 6.5 units
Step-by-step explanation:
Find the diagram attached.
From the diagram, you can see that the dotted triangle is a right angled triangle with side AD as the hypotenuse.
To get AD, we will use the pythagoras theorem as shown;
Hyp² = Opp² + Adj²
AD² = 6²+2.5²
AD² = 36 + 6.25
AD² = 42.25
AD = √42.25
AD = 6.5
Hence the measure of length segment AD is 6.5 units

Tony has x quarters. Jane has three more quarters than Tony. Rob has twice as many quarters as Jane. Together, Rob and Jane have $4.50 in quarters. Complete each statement. (A) The expression x + 3 represents the number of quarters Jane has. (B) The expression x – 3 represents the number of quarters Rob has. (C) Tony has quarters.
Answers
Answer:
x = 3 quarters
Step-by-step explanation:
Tony = x quarters
Jane = (x + 3) quarters
Rob = 2(x + 3) quarters
Rob and Jane have $4.50 in quarters.
$1 = 4 quarters.
$4.50 = ( 4 × 4.5 ) quarters
= 18 quarters.
(x + 3) + 2(x + 3) = 18
x + 3 + 2x + 6 = 18
3x + 9 = 18
3x = 18 - 9
3x = 9
x = 9/3
x = 3
(A) The expression x + 3 represents the number of quarters Jane has. YES
x + 3
= 3 + 3
= 6 quarters
(B) The expression x – 3 represents the number of quarters Rob has.
NO
(C) Tony has quarters.
Tony = x quarters
= 3 quarters
Rob = 2(x + 3) quarters
= 2(3 + 3) quarters
= 2(6) quarters
= 12 quarters
Answer:
(A) The expression x + 3 represents the number of quarters Jane has.
B) The expression 2(x+3) represents the number of quarters Rob has.
(C) Tony has 3 quarters.
Step-by-step explanation:
The surface area of Earth is approximately 5.1 x 108 km2. The surface area of Jupiter is approximately 6.2 x 1010 km2. Approximately
how many times larger is Jupiter's surface area than Earth's surface area?
A 8
B 12
C 80
D 120
Answers
Answer:
The correct answer is: Option D: 120
Step-by-step explanation:
Given that
[tex]S_E = 5.1*10^8\ km^2\\S_J = 6.2*10^{10}\ km^2[/tex]
In order to find how much larger is the area of Jupiter we will divide the surface area of Jupiter by the Surface area of Earth. First of all we will have to equate the exponents of 10 so that the cutting can be done
Now,
[tex]= \frac{S_J}{S_E}\\= \frac{6.2*10^{10}}{5.1*10^8}[/tex]
10^10 can be written as: 10^8*10^2
[tex]=\frac{6.2*10^2*10^8}{5.1*10^8}\\= \frac{6.2*100}{5.1}\\=\frac{620}{5.1}\\=121.5686[/tex]
Closest to 121 is 120.
Approximately Jupiter's surface area is 120 times larger then Earth's surface area.
Hence,
The correct answer is: Option D: 120

Long division is easier than you think. Here's how to solve this problem:
1. See how many times 36 can go into 66.
Multiply until you reach a number that is closest (or exact) to 66.
36 x 1 = 36; 36 x 2 = 72.
72 is over 66, so 2 doesn't work. Therefore, we'd put "1" in the first space on the shelf (right above the 6).
2. Subtract.
Now that we have "1" on the shelf, you need to subtract 36 by 66. We do this because 36 x 1 is 36. If it were the number "2" on the shelf, we'd subtract 72, and so on.
66 - 36 = 30.
3. See how many times 36 can go into 30.
Since it can't go into 30, we bring the 3 down (hence the arrow pointing down). The number is now 303.
4. See how many times 36 can go into 303.
I won't write it all out, but after multiplying 1-7 by 36, we find that the closest solution is 36 x 8 = 288.
We put "8" on the shelf, next to "1".
5. Subtract.
Now that "8" is on the shelf, we subtract 288 by 303, which gives us 15.
Since 36 cannot go into 15, and there are no more numbers we can drag down, your remainder is 15.
Your answer is:
36 R 15
The first two boxes under 663 should be filled with 36, the next three under that should have 303, the next three should have 288, and the final two boxes should have 15.
