Answer:

Mika's estimated the sum to be 216. The actual sum is 216.27

Step-by-step explanation:

Mika:

189.27 = 189

15.8 = 16

11.2 = 11

189 + 16 + 11 = 216

Actual:

189.27 + 15.8 + 11.2 = 216.27

Answer:

90 - 37 will give a solid 53

Step-by-step explanation:

the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)

and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37

now we add angle degrees and sum and subtract one another,

90 - 37

Answer:

square with sides of 6 in

Step-by-step explanation:

Tessellation is the arrangement of shapes in repeated patterns without gaps or overlapping.

Tessellation is usually done with regular polygons. Only three regular shapes can tessellate, these are equilateral triangle, regular square and regular hexagon. For other polygon to tessellate, more than one shape must be used. A octagon can be used to make tessellations if it is used together with a square.

Mark uses tiles with shape of octagon of sides 6 in. To fill the gaps, Mark have to uses a square with sides of 6 in

Answer: 12.6 years

Step-by-step explanation:

Answer:

a = 15, b = -14

Step-by-step explanation:

From the question,

a/5 - b/2 = 10

Multiply all through by 10

(a/5)10 - (b/2)10 = 10×10

2a - 5b = 100...................... Equation 1

a - b = 29 ........................ Equation 2

Solving equation(1 ) and equation (2) simultaneously

using elimination  method,

multiply equation (2) by 2.

2a - 2b = 58.................... Equation 3

Substract equation 3 from equation 1

2a - 2a -5b-(-2b) = 100-58

0 - 5b+2b = 42

-3b = 42

b = 42/-3

b = -14.

Substitute the value of b into equation 2

a - (-14) = 29

a +14 = 29

collect like terms

a = 29-14

a = 15.

Hence, a = 15, b =-14

Answer:

-86x^2 -2x - 8

Step-by-step explanation:

The solution is:

6x²+2x²+3x-4x-9+1  becomes 8x²- x -8.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Here, we have,

Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).

To  subtract -2x^2+4x-1 from 6x^2+3x-9,

that is

6x^2+3x-9 - (-2x^2+4x-1).

This can be written as

6x²+3x-9 - (-2x²+4x-1)

Now, opening the bracket, we will get

6x²+3x-9 +2x²-4x+1

Then, collecting like terms, we get

6x²+2x²+3x-4x-9+1

6x²+2x² = 8x²

3x-4x = -x

-9+1 = -8

∴6x²+2x²+3x-4x-9+1  becomes 8x²-x -8

The answer is 8x²-x -8.

Answer:

1.35m

Step-by-step explanation:

A 2.7 meter ladder leans against a house forming a 30° angle with the house. Exactly how far is the base of the ladder from the house?

We solve the above question using the Trigonometric function of Sine

cos theta = Opposite/Hypotenuse

From the question

Opposite = Distance of base of the ladder from the house = x

Hypotenuse = Length of the ladder = 2.7m

Theta = 30°

Hence,

sin 30 = x/2.7 m

Cross Multiply

x = sin 30 × 2.7m

x = 1.35m

Option b is correct.

The base of the ladder from the house is 1,35 meters, the correct option is B.

Given

A 2.7-meter ladder leans against a house forming a 30° angle with the house.

The sine of an angle is a function that relates to the sides of a right triangle.

Let the base of the ladder from the house be x.

The height of the base of the ladder from the house is given by;

[tex]\rm Sin\theta =\dfrac{Opposite \ side}{Hypotenuse}[/tex]

Substitute all the values in the formula

[tex]\rm Sin\theta =\dfrac{Opposite \ side}{Hypotenuse}\\\\\rm Sin30=\dfrac{h}{2.7}\\\\h = 2.7 \times sin30\\\\h=2.7 \times 0.5\\\\h=1.35 \ meter[/tex]

Hence, the base of the ladder from the house is 1,35 meters.

1) y = 2x + 5

Slope = 2

8y and 6xy i think

Answer:

s(x)

Step-by-step explanation:

s(x) is a linear function, so the average rate of change is its slope.

Its slope is 3.

You are correct.

To find the average rate of change of polynomial function t(x) from -2 to 2, find the values of t(x) at x = -2 and at x = 2.

average rate of change = [t(2) - t(-2)]/[2 - (-2)]

t(x) = 0.1(x^3 - x^2 + 2)

t(-2) = 0.1[(-2)^3 - (-2)^2 + 2)]

t(-2) = 0.1(-8 - 4 + 2)

t(-2) = -1

t(2) = 0.1[(2)^3 - (2)^2 + 2)]

t(2) = 0.1(8 - 4 + 2)

t(2) = 0.6

average rate of change = [t(2) - t(-2)]/[2 - (-2)]

average rate of change = [0.6 - (-1)]/4

average rate of change = 1.6/4

average rate of change = 0.4

average rate of change for s(x) = 3

average rate of change for s(x) = 0.4

Answer: s(x)

When there is no width, the area is 0m²

Step-by-step explanation:

Expressing the area of a rectangle as a function of its width:

Area of a rectangle = Length * width

Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0

When x :

Area = Length * width

Area = Length * 0
