Evaluate the expression 6•14-(9+8)2

Mathematics
1 answer:
lora16 [44]3 years ago
8 0

Answer:

50

Step-by-step explanation:

First things first, use PEMDAS.

Parenthesis is first.

(9+8) is in parenthesis. 9+8 is obviously 17.

The equation now looks like this:

6 x 14 - 17 x 2

There is no exponents, but there is multiplication. 6 x 14 is 84 and 17 x 2 is 34. They both are multiplication equations.

The equation now looks like this:

84 - 34

84-34 is 50. 50 is your answer.

Leonel is building a circular table with a diameter of 5 feet. The wood costs $35.50 per square foot. How much will it cost Rafa
kiruha [24]

Answer:

$696.70

Step-by-step explanation:

The formula for the area of a circle is given as πr²

From the above question

π = 3.14

Diameter = 5 feet

Radius = Diameter/2 = 5 feet/2 = 2.5 feet

Hence,

The area of the circular table = 3.14 × 2.5²

= 19.625 ft² or 19.625 square foot

We are told that:

The wood costs $35.50 per square foot

Hence,

1 ft² = $35.50

19.625 ft² = x

Cross Multiply

x = 19.625 ft² × 35.50

x = $696.6875

Approximately = $696.70

Therefore, it will cost Rafael $696.70 to make the table.

The measure of each angle in the triangle
telo118 [61]
M of A = x
m of B = 2x-7
m of C = 2x+2

By the angle sum property of a triangle, we know that all the angles of a triangle add up to 180 degrees.

Thus we can create a linear equation

x + 2x-7 + 2x+2 = 180
4x = 185
x = 185/4
x = 46.25

Thus
m of A = 46.25
m of B = 2(46.25) -7 = 85.5
m of C = 2(46.25) +2 = 90.5
