andre [41]2 years ago
3 0

Answer:

x= 20

Step-by-step explanation:

The sum of the three angles is 90 degrees

x+2x+x+10 = 90

Combine like terms

4x+10 = 90

Subtract 10

4x+10-10 = 90-10

4x= 80

Divide by 4

4x/4=80/4

x = 20

2. Express each of the following as a rational number in the form of p/q<br> Where q≠0
ANTONII [103]

Step-by-step explanation:

We need to find each of the following as a rational number in the form of p/q

(a) (3/7)²    (b) (7/9)³  (c) (-2/3)⁴

Solution,

(a) (3/7)²

(\dfrac{3}{7})^2=\dfrac{9}{49}

(b) (7/9)³

(\dfrac{7}{9})^3=\dfrac{7\times 7\times 7}{9\times 9\times 9}\\\\=\dfrac{343}{729}

(c) (-2/3)⁴

(\dfrac{-2}{3})^4=\dfrac{-2\times -2\times -2\times -2}{3\times 3\times 3\times 3}\\\\=\dfrac{16}{81}

Hence, this is the required solution.

A college offers shuttle service from Dickson Hall or Lot B to its
Alchen [17]

Answer:

At 10:30 A.M.

Step-by-step explanation:

A college offers shuttle service from Dickson Hall or Lot B to its  campus quad.

At 9:10 A.M the first shuttle leaves from their locations for the campus.

If the shuttles leave from Lot B every 10 minutes and leave from Dickson Hall every 12 minutes, then both the shuttles will leave their origin at the same time after 60 minutes.

This is because 60 is the smallest multiple of 10 and 12 which is common for them.

Therefore, 10:30 A.M. is the next time when both shuttles will depart for the campus at the same time. (Answer)
