Answer:

1 - Avenue A is perpendicular to South St.

2 - 70°

Step-by-step explanation:

1 - North, Center, and South St. are parallel lines. Therefore Ave A will be perpendicular to the three lines.

2 - Ave B and Center street forms a 70° angle. Since Center and South St. are parallel lines, they have corresponding angles. Therefore, Ave B and South St also form a 70° angle. The same is true for Ave B and North St.

I'm thinking of a three digit number it is an odd multiple of threes and the product of its digits 24. It is larger than 15^2. W
ipn [44]

Answer:

243, 381, 423, 813, 831

Step-by-step explanation:

The product of its digits is 24, so we have opptions:

1,3,8 because 1*3*8=24

1,4,6 becaus 1*4*6=24

2,3,4 because 2*3*4=24

2,2,6 becaus 2*2*6=24

They can be divide by 3, so the sum of its digits can be divide by 3:

1+3+8=12 (It is OK)

1+4+6=11 (It is not ok)

2+3+4=9 (it is OK)

2+2+6=10 (it is not OK).

Now we have less opportunities, it is number of digits:

1,3,8 and 2,3,4.  In wich order we will se!:)

From the informations we know that three numbers are odd number and greater then 15*15=225

Therefore, for 1,3,8 it must be that  1 ro 3 is least digit (its odd number) that numbers are:

183, 813, 831, 381

greater then 225 are 381,831,813.

For digits 2,3,4 it must be that 3 is the least digit (number is odd) so we have:

243 and 423. Both are greater than 225.

Please help me i will give Brainly
Degger [83]

Answer:

Step-by-step explanation:

\frac{3x + 5}{2x + 7} = 5

do cross multiplication

3x + 5 = 5(2x + 7)

3x + 5 = 10x + 35

5 - 35 = 10x - 3x

-30 = 7x

-30/7 = x

20 A

since there are 7 angles given it means that the polygon is heptagon as heptagon has 7 sides.

sum of interior angle of heptagon = (n-2)*180

(7-2)*180

5*180

900

Now ,

110 + 90 + 150 + 102 + 110 + 170 + x = 900

732 + x = 900

x = 900 - 732

x = 168 degree

20 B

since 5 angles are given it means that the polygon is pentagon as pentagon has 5 sides.

sum of interior angles of a pentagon = (n-2)*180

(5-2)*180

3*180

540 degree

Now ,

110 + 95 + 120 + 114 + x = 540

465 + x = 540

x = 540 - 465

x = 75 degree

21

let one rational number be x

according to the question,

1/7 * x = 2

x/7 = 2

do cross multiplication

x = 14

Natalie went to the shoe store and bought two pairs of sneakers. One pair was $35.60, and the other was $49.95. If she has $100.
Contact [7]

First you need to add the prices to get 85.55. Then 100 - 85.55 is 14.45.




She will have $14.45 leftover
