Answer:

The answer is -3

Step-by-step explanation:

The answer is -3 because of the order of operations PEMDAS (parenthesis, exponent, multiplication/division, addition/subtraction)

Therefore, you would multiply the two numbers inside the parenthesis first, which would give you 15-18, and from there you can subtract 18 from 15 which would give you -3.

dolphi86 [110]

Answer:

92776

Step-by-step explanation:

From the given question,

The analysis of the given question can be computed as follows:

I have 5 digits

My name is worth 90000

my two is worth 2000

one of my seven is worth 70

and the other is worth 10 times

as much i.e 10× 70 = 700 700

my other digit is six 6

What number am I?

So, we are expected to look for the summation of all the numbers

i.e 90000 + 2000 + 70 + 700 + 6

= 92776

Thus, the number is 92776

Please help me by the way this is a 2 mark question from mathswatch

BigorU [14]

Answer:

y = - 13, y = 13

Step-by-step explanation:

Given

y² = 169 ( take the square root of both sides )

y = ± $\sqrt{169}$ = ± 13

Since 13 × 13 = 169 and - 13 × - 13 = 169

Remi has two cone-shaped containers with the same diameter. He will place the smaller container inside the larger one. Before he

Keith_Richards [23]

Given:
Big cone : diameter = 12 cm ; height = 18 cm ; base = 14 cm
Small cone: diameter = 12 cm ; height = 6 cm ; base = 14 cm

Volume of a cone-shaped container = π r² h/3
Big cone:
V = 3.14 * (6cm)² * 18cm/3
V = 3.14 * 36cm² * 6cm
V = 678.24 cm³

Small cone:
V = 3.14 * (6cm)² * 6cm/3
V = 3.14 * 36cm² * 2cm
V = 226.08 cm³

Big cone - small cone = volume of water
678.24 cm³ - 226.08 cm³ = 452.16 cm³
