T = p + 50

Mathematics
1 answer:
RUDIKE [14]3 years ago
7 0
The only way i can think of working out this question is this:

t = time p = phone calls

insert what we know:-

93 = p + 50

make P on its own:-

take away 50 from each side

43 = p

switch (you don’t HAVE to do this) :-

p = 43

So, shivani has to route a total of 43 phone calls to spend a total of 93 minutes on the phone.

Two different sizes of square metal duct are joined by a piece that is a frustum of a pyramid. Find the lateral surface area, if
Allisa [31]

Answer:

288 in²

Step-by-step explanation:

The formula used to solve this question is :

Lateral Surface Area = s( P1 + P2)

Where s = slant height = 2 inches

P1 and P2 = Perimeter of the bases

Perimeter of base 1 = 4 × length of the end of the small square

4 × 17 inches = 68 inches

Perimeter of base 2 = 4 × length of the end of the large square

4 × 19 inches = 76 inches

Lateral Surface Area = 2 × (68 + 76)

= 2 × 144

= 288 in²

a system of equations has infinitely many solutions. if 2y – 4x = 6 is one of the equations, which could be the other equation?
deff fn [24]
<span>A system of equations has infinitely many solutions when the two lines representing the equations coincide. i.e. the two equations are the same or a multiple of each other.
2y - 4x = 6
2y = 4x + 6
2y = 2(2x + 3)
y = 2x + 3
-y = -(2x + 3)
-y = -2x - 3
Hence the other equation is -y = -2x - 3</span>
