Answer:

550.4 square units.

Step-by-step explanation:

This problem is easier than it seems.

To find the area of the parallelogram, multiply 11 and 32 to get 352 sq. units

The two semicircles must be equal because the sides of a parallelogram must be equal.

So if you add the semicircles together, you get a circle.

So we're really finding parallelogram+circle.

The area of a circle is [tex]\pi[/tex]x[tex]r^{2}[/tex], and the circle's radius is 8 because the radius is half of the diameter.

[tex]\pi[/tex]≈3.1 because you're rounding to the nearest tenth.

3.1x64=198.4 sq. units

198.4+352=550.4 square units.

The equation of the line in fully simplified slope - intercept form is 5x + y = 8 .

In the question ,

a graph of the line is given , we need to find the equation of the given line in the simplified slope - intercept form .

to find the equation , we need minimum two points ,

So , from the graph

we can see that

when x [tex]=[/tex] 0 , the value of y [tex]=[/tex] 8 ,

the first point is (0 [tex],[/tex] 8) .

when x [tex]=[/tex] 2 , the value of y [tex]=[/tex] -2 ,

the second point is (2 [tex],[/tex] -2) .

the slope can be calculated by

slope = (-2-8)/(2-0)

= -10/2

= -5

So , the equation of the line passing through point (2,-2) with slope -5 , in the slope intercept form is

(y -(-2)) = -5(x-2)

y + 2 = -5x + 10

Simplifying further , we get

5x + y = 10 - 2

5x + y = 8

Therefore , The equation  line in fully simplified slope - intercept form is 5x + y = 8 .

The given question is incomplete , the complete question is

Write the equation of the line in fully simplified slope-intercept form, the line graph is shown below .

The range of values for the rectangle  length is  20 ≤ y ≤ 30 .

What is a rectangle made of?

The garden is to be rectangular shape.

Let x = width

Let y = length

Set the equations for perimeter and area.

2(x + y) = 100  -----> perimeter

x + y = 50   ------> perimeter

xy = 600   ---->  area

We have two equations to work with.

x + y = 50                eq1

xy = 600                   eq2

Substitute eq1 into eq2.  We can get eq2 in terms of x.

x(50 - x) = 600

-x2 + 50x = 600

-x2 + 50x - 600 = 0

Divide both sides of the equation by -1, so that we have a positive x2.  The goal is to try to use FOIL to factor.

x2 - 50x + 600 = 0

(x - 30)(x - 20) = 0

x = 30         and           x = 20

Next, we plug in these values of x into eq1 to solve for y.

y = 50 - x                     and                y = 50 - x

y = 50 - 30                                        y = 50 - 20

y = 20                                               y = 30

Based on this, the range of values for the length is

The values of a and b are 8 and - 9.

Given that:

f(x) = x + a/x + b ........ (1)

f(1) = 0, f(2) = - 3

Putting the value of x = 1 in equation (1). We get,

f(1) = 1 + a/1 + b

f(1) = 1 + a + b ....... (2)

Putting the value of x = 2 in equation (1). We get,

f(2) = 2 + a/2 + b

f(2) = (4 + a + 2b)/2 ........ (3)

Putting the value of f(1) = 0 in equation (2). We get,

a + b = - 1 ......... (4)

Putting the value of f(2) = -3 in equation (3). We get,

=> -3 = (4 + a + 2b)/2

=> -6 = (4 + a + 2b)

=> a + 2b = - 10 ......... (5)

To find the value of a and b we have to solve equations (4) and (5) by elimination method.

So, for that subtract equation (4) from (5).

We got the value of b = - 9.

Then put the value of b in equation (4).

We got the value of a = 8.

Checking the value of a and b satisfies the value of the function's output and input.  

Hence,  the values of a and b are 8 and - 9 respectively.

The absolute value graph has its equation to be f(x) = |x - 3| + 5

The graph represents the given parameter

From the graph, we can see that the graph is an absolute value graph

An absolute value graph is represented as

f(x) = a|x - h| + k

Where h and k are the vertex of the graph

In this case, they are

h = 3 and k = 5

This is because the minimum point of the graph is (3, 5)

Substitute values for h and k in the form of the equation

So, we have the following representation

f(x) = a|x - 3| + 5

A point on the graph is (2, 6)

This gives

a|2 - 3| + 5 = 6

When the value of variable a is solved, we have

a = 1

So, the equation becomes

f(x) = 1 * |x - 3| + 5

Evaluate the products

f(x) = |x - 3| + 5

Hence, the equation of the graph is f(x) = |x - 3| + 5

Answer: 1/4

Step-by-step explanation:

0.75 liters is the same as 750 grams.

So, the total mass of the mixture is [tex]300+150+750=1200[/tex] g.

This means the ratio is [tex]\frac{300}{1200}=\frac{1}{4}[/tex].

Answer:

Flour : total mass = 1 : 4

Step-by-step explanation:

Given ingredients for the cake:

First convert the mass of the water to the same SI units as the other ingredients.

1 liter = 1000 g

⇒ Water = 0.75 liters = 750 g

Total mass of the mixture:

= flour + sugar + water

= 300 g + 150 g + 750 g

= 1200 g

Therefore, the flour to total mass ratio is:

⇒ Flour : total mass = 300 : 1200 = 1 : 4

The original coordinates are R= (-6,-6) and S = (-4,0)

What is translation?

Translation in mathematics is a property in which we shift each coordinate on a line by a constant value.

We are given that we originally had a segment RS which is reflected over the line y = x and then translated by (x+3, y+4) after this the segment we get the coordinates are R'' (-1,4) and S( -3,-2)

We are asked to find the coordinates of R and S

To find the coordinates we first reverse the process we subtract 3 from both x coordinate and 4 from both y coordinate

Hence we get,

R' = (-1,4)-(3,4)

R' = (-4,0)

And

S' = (-3,-2)-(3,4)

S' = (-6,-6)

Now to find the original coordinates we reverse the coordinates

Hence we get,

R= (-6,-6) and S = (-4,0)

Therefore the coordinates are R= (-6,-6) and S = (-4,0)

When the statement is rewritten as a conditional statement in if-then form, the option that best describes the hypothesis is B. Two lines intersect at a point

A conditional statement is one that has the form "If P then Q," where P and Q are sentences. P is referred to as the hypothesis in this conditional statement, and Q is referred to as the conclusion. "If P then Q" implies that Q must be true whenever P is true.

There is a conditional statement. We will not play if it is raining. Let's say A: it's raining and B: we're not going to play. If A is true (it is raining) and B is false (we played), then the statement A implies B is false.

If the original sentence is restated as an if-then conditional statement, the hypothesis is best described as two lines intersecting at a point. As a result, the statement "Two lines intersect at a point" is the correct option (B) and the best option.

Step-by-step explanation:

The percentage decrease of the population of a city is 19%.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

In this case, the population of a city was 325,000 and several years later it was 263,250.

The percentage decrease will be:

= Decrease in population / Original population × 100

= (325000 - 263250) / 325000 × 100

= 61750 / 325000 × 100
