what is 8 7/8+1/2 and what is 45.35 + 40 7/10

Answer

Check Explanation

Explanation

To reflect a point A (x, y) over the y-axis, the new coordinates become A' (-x, y)

For the point B(x, y) over the x-axis, the new coordinates become B'(x, -y)

So, reflecting the point (1, -4) over the y-axis, we have (-1, -4)

Reflecting the point (1, -4) over the x-axis, we have (1, 4)

Reflecting (1, -4) over both x-axis and then y-axis, we have (-1, 4)

In the given parallelogram

From the property of diagonals of Parallelogram

The diagonals are bisect each other into equal parts

So, according to the figure

length 2x= length of y

2x=y

Similarly for the second diagonal,

length y+4=length3x

y+4=3x

Simplify the both equation by substitution method,

In substitution method, substitute the value of any one varibale and put into the another equation and simplify

Now substitute the value of x=4 into the first equation and simplify for y

So the value of varriables x = 4 and y=8

Answer : A) x=4, y=8

Given data:

The given figure of cylinder.

The total surface area of the cylinder is,

Substitute the given values in the above expression.

We have the following function f(x) = x^3+2x^2 -18. We want to solve the following equation

By subtracting 9 on both sides, we get the equivalent equation

Convert 54.158 degrees

Firstly, Use the whole number as degree

54 degree

to convert to minutes

(54.548 - 54) x 60

= 0.158 x 60

= 9 minutes

To convert to seconds

(54.158 - 54 - 9/60) x 3600

= (0.158 - 0.15) x 3600

= 0.008 x 3600

= 28.8 seconds

This can be written as

We have the next system of equations:

Substituting y = 3x + 19 into the second equation, and solving for x:

Substituting x = -7 into the first equation:

The solution is (-7, -2)

Given a right angle triangle ABC:

As the measure of angle C = 90

so, the sum of the angles A and B = 90

So, angles A and B are complementary angles

so,

so, the answer will be cos B = 3/5

The equation 2y - 3x = 5 has infinitely many solutions.

In this question, we have been given an equation 2y-3x=5

We need to solutions to given equation.

for x = -1,

2y -3(-1) = 5

y = 1

for x = 0,

2y - 3(0) = 5

y = 5/2

y = 2.5

for x = 1,

2y - 3(1) = 5

y = 4

In this way for any real value of x we can find infinitely many values of y.

Therefore, the equation 2y - 3x = 5 has infinitely many solutions.

To find the decimal values you have to count the number of shaded squares and divide it by the total number of squares in the grid.

Left value:

The grid is 10 x 10, which means that it is divided into 100 squares.

There are 23 shaded squares in the grid, so you can determine the decimal value as follows:

Right value:

The grid is 10 x 10, so it is divided into 100 squares.

The number of shaded squares is 62. Divide 62 by 100 to determine the decimal value:

Now what is left to do is to add both decimal values:

Given:

A triangle is formed by three roads that connect Shelbyville, Springfield, and Capitol City together.

These roads are 19, 21, and 24 miles long.

So, as we can see the three sides are different in lengths

So, the answer will be:

This forms a scalene triangle.

a) A U (B ∩ C)

In order to obtain the result for the previous set, first find (B ∩ C)

∩ is the intersection operation (the result is a set with common elements in the implied sets) Based on the given sets, for interection operation, you get:

(B ∩ C) = {e , g}

Next, the union operation with A results (union operation results in a set with all values of both sets but without repeating elements):

A U (B ∩ C) = {c , d , e , f , g}

b) A' ∩ (B U C)

A' is the complement of A (all values of the universe not present in A). In this case:

A' = {a , b , g}

B U C = {a , c , e , f , g}

Then:

A' ∩ (B U C) = {a , g}

c) A i (B' ∩ C')

B' = {b , d , f}

C' = {a , b , c , d}

B' ∩ C' = {b , d}

Then:

A ∩ (B' ∩ C') = {d}

Step-by-step explanation:

The height of the water level after 1 hour is 2.4 units.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is h(x)=0.4x+2.

Given input value is x=1

So, the height of the water level is

h(1)=0.4(1)+2

= 0.4+2

= 2.4 units

Therefore, the height of the water level after 1 hour is 2.4 units.

Given:

The total number of seats, T=750.

Let x be the number of seats in a row and y be the number of rows.

It is given that the number of seats in a row is 5 less than the number of rows.

Hence, the number of seats in a row can be expressed as,

Now, expression for the total number of seats can be given by,

Plug in x=y-5 and T=750 in the above equation and simplify.

The equation (1) is in the form of a quadratic equation of the form,

Comparing equations (1) and (2), a=1, b=-5 and c=-750.

Now, using discriminant method, the solution of y can be expressed as,

Since the number of rows cannot be negative, y=30.

Put y=30 in equation (a) to find x.

Therefore, the number of seats in a row is 25.
