Answers

Answer 1

Answer:

1

Step-by-step explanation:

first, you have to combine the two equations.

f(x)+ g(x)

3x^2 +4x+2= (that haha)

now substitute -1 for x

3(-1)^2 +4(-1)+2

(3×1) +(-4)+2

A rectangular boad is 1100 millmeters long and 900 millmeters wide. what is the area of the board in square meters?

Answers

Answer:

1100 mm = 1.1 m, and 900 mm = 0.9 m.

So the area is 1.1 x 0.9 = 0.99 m^2

The area of the rectangular board is 0.99 square meters.

Given that a rectangular board is 1100 millimeters long and 900 millimeters wide.

We need to find the area of the board,

To find the area of the rectangular board in square meters, we need to convert the given dimensions from millimeters to meters and then calculate the area.

Given:

Length of the board = 1100 millimeters

Width of the board = 900 millimeters

To convert millimeters to meters, we divide the given values by 1000:

Length in meters = 1100 mm / 1000 = 1.1 meters

Width in meters = 900 mm / 1000 = 0.9 meters

The formula to calculate the area of a rectangle is:

Area = Length × Width

Substituting the values, we get:

Area = 1.1 meters × 0.9 meters

Area = 0.99 square meters

Therefore, the area of the rectangular board is 0.99 square meters.

Answers

Answer:

apple $9pumpkin $10

Step-by-step explanation:

Let 'a' and 'p' stand for the prices of apple and pumpkin pies, respectively. Then the two sales are described by ...

  4a +5p = 86

  8a +2p = 92

Subtract half the second equation from the first to eliminate the 'a' variable.

  (4a +5p) -(1/2)(8a +2p) = (86) -(1/2)(92)

  4p = 40 . . . . . simplify

  p = 10 . . . . . . . divide by 4

Substitute into the first equation:

  4a + 5(10) = 86

  4a = 36 . . . . . subtract 50

  a = 9 . . . . . . . divide by 4

One apple pie costs $9; one pumpkin pie costs $10.

Ed bus a box of eggs costing £2.30, two packs of bacon for £2.60 each and two tins of baked beans. He pays with a £10 note gets 80p change how much did the tin of beans cost?

Answers

Answer:

£0.85 for each

£1.70 for both

Step-by-step explanation:

Variable x = cost of baked beans

2.30 + 2(2.60) + 2x = 10 - 0.80

Use PEMDAS

2.30 + 5.20 + 2x = 10 - 0.80

7.50 + 2x = 9.20

Subtract both sides by 7.50

2x = 1.70

Divide both sides by 2 to isolate the variable

x = 0.85

Let's check our work by plugging this into our original equation

2.30 + 2(2.60) + 2(0.85) = 10 - 0.80

2.30 + 5.20 + 1.70 = 10 - 0.80

7.50 + 1.70 = 9.20

9.20 = 9.20

Our number is correct

Answer:

B) 120 degrees

Step-by-step explanation:

The two triangles are the same, so first find the measure of angle B.

To do this first solve for angles A and C. Solve for A first: 4x or 4(5), which is 20 degrees. Now solve for C: 8x or 8(5), which is 40 degrees. Add 40 + 20 degrees to get 60 degrees total of those two angles.

A triangle has 180 total degrees, so to solve for the measure of Angle B, subtract 180 - 60 to get 120 degrees.

Since the two triangles are the same, Angle D is the measure as Angle B.

Answer:

42

Step-by-step explanation:

line TZY is a straight line

Total angles on a straight line is 180

Since angle XZT + XZY = 180

98 + XZY = 180

XZY = 82

angle XYZ + YXZ + XZY = 180

XYZ + 56 + 82 = 180

XYZ + 138 = 180

XYZ = 180 - 138
