HURRY NEEDED BY SATURDAY​

Answers

Answer:

42°

Step-by-step explanation:

the exterior angle is equal to the sum of the 2 far angles from it (from the exterior angle)

so 98-56=42°

hope you understand it

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

XYZ = 42

x=9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12=x+3

Step 2: Flip the equation.

x+3=12

Step 3: Subtract 3 from both sides.

x+3−3=12−3

x=9 because 9+3=12 so the answer is 9

The inner circle circumference is 52 ft. the distance between the inner and the outer circle is 8ft. By how many ft is the outer circle larger?

Answers

Answer:

The outer circle is 16 feet larger than the inner circle (68 - 52).

Step-by-step explanation:

Given that the inner circle circumference is 52 feet, and the distance between the inner and the outer circle is 8 feet, to determine by how many ft is the larger outer circle, the following calculation must be performed:

The radius of a circle is equal to half its diameter. Therefore, the radius of the inner circle is 26 feet. Thus, if the distance between the two circles is 8 feet, the radius of the outer circle is 34 feet (26 + 8). Therefore, the diameter of this circle is 68 feet (34 x 2).

This implies that the outer circle is 16 feet larger than the inner circle (68 - 52).

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:

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.

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

Answers

Answer:

Step-by-step explanation:

From the table attached,

x-intercept of the linear function is, the value of 'x' when f(x) = 0  

x = 3 [x-intercept]

Function 'g' is the sum of 2 and the cube root of the sum of three time x and 1.

g(x) = [tex]2+\sqrt[3]{3x+1}[/tex]

For x-intercept,

g(x) = 0

[tex]2+\sqrt[3]{3x+1}=0[/tex]

3x + 1 = (-2)³

3x + 1 = -8

3x = -8 - 1

3x = -9

x = -3

Therefore, the x-intercept of function 'f' is different or greater than the x-intercept of function g.
