Answer:

A and B

A and C

Step-by-step explanation:

Common internal tangents intersect the segment joining the centers of the two circles.

Tangent I is common internal tangent to circles A and B as the line joining the centers of circles will intersect the tangent I.

Tangent I is also a common internal tangent to circle A and C.The line joining the centers of circles A and C intersects tangent I .

Tangent I is not a common internal tangent to circles B and C,

A store receives shipments of peaches and wants to sort them by weight. Drag each shipment to match the ratio of peaches to poun
Andrej [43]

Answer:


Step-by-step explanation:

Given that a store receives shipments of peaches.  They want to sort them by weight.

The sorting pattern is as follows:

Peaches : Pound = 2:1 or 3.25:1 or 1:3.25

Given are i) 26 peaches to 13 lbs = 26:13=2:1 Hence goes to the first box

ii) 6 peaches to 19.5 lbs =6:19,5 = 1:3,25 lb. Hence goes to II box

iii) 13 peaches to 4 lbs: =13:4=3.25:1   Hence goes to II box

iv) 39 peaches to 12 lbs: =39:12=3.25:1   Hence goes to II box

v) 15 peaches to 7.5 lbs: =15:7.5=2:1   Hence goes to I box

i    - I box

ii   -  II box

iii   - II box

iv) -   II box

v) - I box

Solve for x 3x−91>−87 OR 21x−17>25
klasskru [66]

Answer:

  x > 4/3

Step-by-step explanation:

The first inequality can be solved this way ...

  3x -91 > -87

  3x > 4 . . . . . . . add 91

  x > 4/3 . . . . . . divide by 3

__

The second inequality has solution ...

  21x -17 > 25

  21x > 42 . . . . . . add 17

  x > 2 . . . . . . . . . divide by 21

__

The solution set is the union of these overlapping solutions, so will be equal to the first solution:

  x > 4/3

I hope this helps....

let one kg of potatoes be x
let one kg of carrots be y
8x + 5y = 28
(4) 2x + 3y = 11.2 (4)
8x + 12y = 44.8

7y = 16.8
y=2.4

According to the Rational Root Theorem, which is a factor of the polynomial f(x) = 3x3 – 5x2 – 12x + 20?
Harlamova29_29 [7]

3x^3 – 5x^2 – 12x + 20

= (3x^3 – 5x^2) – (12x - 20)

= x^2(3x - 5) - 4(3x - 5)

= (3x - 5)(x^2 - 4)

= (3x - 5)(x + 2)(x - 2)


Factors: (3x - 5), (x + 2), and (x - 2)


Answer:

D.) 3x – 5
