Answer:

1) [tex]\frac{13}{4}[/tex]

2) [tex]\frac{11}{2}[/tex]

3) [tex]\frac{5}{3}[/tex]

4) [tex]\frac{35}{8}[/tex]

Step-by-step explanation:

we know that

A mixed number is the sum of a whole number  and a fraction number

case 1) we have

[tex]3\frac{1}{4}[/tex]

so

[tex]3\frac{1}{4}=3+\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}[/tex]

case 2) we have

[tex]5\frac{1}{2}[/tex]

so

[tex]5\frac{1}{2}=5+\frac{1}{2}=\frac{5*2+1}{2}=\frac{11}{2}[/tex]

case 3) we have

[tex]1\frac{2}{3}[/tex]

so

[tex]1\frac{2}{3}=1+\frac{2}{3}=\frac{1*3+2}{3}=\frac{5}{3}[/tex]

case 4) we have

[tex]4\frac{3}{8}[/tex]

so

[tex]4\frac{3}{8}=4+\frac{3}{8}=\frac{4*8+3}{8}=\frac{35}{8}[/tex]

Area of a circle = PI x r^2

r is 1/2 the diameter = 0.5 inches

Area = 3.14 x 0.5^2

Area = 0.79 in^2

It looks like it’s missing something...is it a part A ?

Answer:

Part a) The total length of the circular portions is [tex]12\pi\ in[/tex]

Part b) The total length of wire needed is tex]53.7\ in[/tex]

Part c) The total weight of the ornament is [tex]97\ g[/tex]

Step-by-step explanation:

Part a) Find the total length of the circular portions in terms of pi

we know that

The diameter of the circle is equal to the length side of the square

[tex]D=4\ in[/tex]

The total length of the circular portions is equal to the circumference of three complete circle

Because each circular portion is equal to 3/4 of circle

so

[tex](3/4)*4=3[/tex]

The circumference of four three quarter circles is equal to

[tex]C=3(\pi D)[/tex]

substitute the diameter

[tex]C=3(\pi (4))[/tex]

[tex]C=12\pi\ in[/tex]

Part b) Find the total length of wire needed

The total length of the circular portions is [tex]12\pi\ in[/tex]

assume

[tex]\pi =3.14[/tex]

[tex]12(3.14)=37.68\ in[/tex]

The total length of the square portion is equal to

[tex]4b=4(4)=16\ in[/tex] -----> perimeter of a square

Adds the lengths

[tex]37.68+16=53.68\ in[/tex]

Round to the nearest tenth

[tex]53.68=53.7\ in[/tex]

Part c) Find the total weight of the ornament

we know that the ornament weights 1.8 grams per inch

so

Multiply the total length by 1.8 to obtain the total weight

[tex]53.7(1.8)=96.66\ g[/tex]

Round to the nearest gram

[tex]96.66=97\ g[/tex]

Answer:

The area of the shaded sector is [tex]51.2\pi \ units^{2}[/tex]

Step-by-step explanation:

I assume that the problem is

Find the area of the shaded sector of the circle with radius equal to 16 units

step 1

Find the value of x

we know that

[tex]8x+2x=360\°[/tex]-----> by complete circle

[tex]10x=360\°[/tex]

[tex]x=36\°[/tex]

The central angle of the shaded sector is 2x

[tex]2(36\°)=72\°[/tex]

step 2

Find the area of the circle

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=16\ units[/tex]

substitute

[tex]A=\pi (16)^{2}[/tex]

[tex]A=256\pi\ units^{2}[/tex]

step 3

Find the area of the shaded sector

we know that

A central angle of 360 degrees subtends an area of circle equal to [tex]256\pi\ units^{2}[/tex]

so

by proportion

Find the area of the shaded sector by a central angle of 72 degrees

[tex]\frac{256\pi}{360}=\frac{x}{72} \\ \\ x=256\pi *(72)/360\\ \\x=51.2\pi \ units^{2}[/tex]

No and the graph has a greater minimum.

Answer:  YES, Graph

Step-by-step explanation:

Graph: minima (lowest point) is (4, -4)

Equation f(x) = x² - 8x + 7

[tex]x=\dfrac{-b}{2a}=\dfrac{-(-8)}{2(1)}=\dfrac{8}{2}=4\\\\y=(4)^2-8(4)+7\\.\ =16-32+7\\.\ =-9\\[/tex]

minimima is (4, -9)

The x-values are the same

The y-value of the Graph is greater (higher)

Absolutely down graph is true!!

because, certainly 2<y<3

Answer:

y = (-5/4)x + 12.25

Step-by-step explanation:

Slope intercept form:

y = mx + b

Slope form:

m = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (9 , 1)

(x₂ , y₂) = (5 , 6)

Plug in the corresponding numbers to the corresponding variables.

m = (6 - 1)/(5 - 9)

Simplify.

m = (5)/(-4)

Your slope is -5/4

Plug in -5/4 for m in the slope-intercept form equation, and use a point to solve for b. For example, we will use (9, 1):

y = mx + b

y = (-5/4)x + b

(1) = (-5/4)(9) + b

Simplify.

1 = (-11.25) + b

Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Add 11.25 to both sides.

1 + (11.25) = -11.25 (+11.25) + b

1 + 11.25 = b

b = 12.25

your y-intercept is 12.25

Plug in the corresponding numbers to the corresponding variables.

y = mx + b

m = -5/4

b = 12.25

y = (-5/4)x + 12.25 is your answer.

If circle with center O has a radius of 18 centimeters. If the length of arc AB = 6π centimeters then measure of x is 60°

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given,

Circle with centre O,

Radius of circle=18 centimeters

length of arc AB = 6π centimeters

We need to find the measure  θ  of x

We have a formula to find the length of arc.

Length of an Arc = θ × (π/180) × r

Apply the given values in formula

6π=θ × (π/180) × 18

π gets cancelled on both the sides

6=θ/10

θ=60°

Hence if circle with center O has a radius of 18 centimeters. If the length of arc AB = 6π centimeters then measure of x is 60°

Step-by-step explanation:

If Jerry took half the time Macy did then that means Macy took twice as long as Jerry. If Jerry’s speed was r then Macy’s speed is 0.5r or half the speed of Jerry. This will mean Macy goes half as slow and takes twice as long to get there.

To solve the problem, set up two equations: X + Y = 12 and X = 2Y. Using the substitution method, replace X with 2Y in the first equation to find Y = 4, and subsequently find X = 8.

The problem given to us involves finding two numbers, X and Y, given that the sum of these two numbers is 12 and the first number, X, is twice the second number, Y. To solve for X and Y, we can set up a system of two linear equations.

The first equation comes from the sum of the two numbers:

X + Y = 12

The second equation comes from the statement that X is twice Y:

X = 2Y

Now we have a system of equations:

One method to find solutions for X and Y is by substitution. We can substitute 2Y in place of X in the first equation:

Now that we know Y is 4, we can find X using the second equation:

The two numbers are X = 8 and Y = 4.

Since all the answers have (-6), it means that you multiply the whole equation on both sides by 6, which makes a (2/3)x become a 4x and a (1/2) become 3

Answer:

C

Step-by-step explanation:

Start by multiplying through by 3. That is the first of 2 possible steps.

3[2/3 x - 1  = 1/2]

2x - 3 = 3/2              

Now multiply by 2

2 [ 2x - 3 = 3/2]

4x - 6 = 3

That makes C the only possible answer.

What is segment ab? is there a picture that is supposed to go with it?

Answer:  The required co-ordinates of point M are (8, 9).

Step-by-step explanation:  Given that the point M divides segment AB into a ratio of 2 : 3, where A is at (0, 15) and B is at (20, 0).

We are to find the co-ordinates of point M.

We know that

the co-ordinates of a point that divides the line segment joining the points (a, b) and (c, d) are given by

[tex]\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).[/tex]

For the given division, (a, b) = (0, 15), (c, d) = (20, 0) and m : n = 2 : 3.

Therefore, the co-ordinates of point M are given by

[tex]\left(\dfrac{2\times20+3\times0}{2+3},\dfrac{2\times0+3\times15}{2+3}\right)\\\\\\=\left(\dfrac{40}{5},\dfrac{45}{5}\right)\\\\\\=\left(8,9).[/tex]

Thus, the required co-ordinates of point M are (8, 9).

Final answer:

To find w from the equation 3w - 4z = 8, add 4z to both sides, and then divide by 3 to isolate w, giving w = (4z + 8) / 3.

Explanation:

The equation 3w - 4z = 8 is a linear equation in two variables (w and z). To find w in terms of z, you need to isolate w on one side of the equation. Here is the process step by step:

Add 4z to both sides of the equation: 3w - 4z + 4z = 8 + 4z.

Simplify the equation: 3w = 4z + 8.

Divide every term by 3 to solve for w: w = (4z + 8) / 3.

So, w is equal to (4z + 8) / 3 when isolated from the given equation.

Answer:

8.717 both the sides

Step-by-step explanation:

Given:

Let ABC be the given triangle with

angle A= 55

angle B=55

angle C= 70

side across angle C, c= 10 inches

side across angle B, b =?

aide across angle A,a=?

Now using the law of sin to find a and b:

                a/sinA=c/sinC

                a= (c/sinC)(sinA)

Putting the values:

                a= (10/sin70)(sin55)

                a= 8.717

As the given triangle is isosceles so side a=b

hence a=b= 8.717 inches !

Answer: The answer is 12.6 Meters Squared

You get that from multiplying 120 to 3.5 and 2.5 . After doing that you will get 420 cm and 300 cm. Knowing that a meter is 100 cm you will get 4.2 meters and 3 meters. To find the area of the kitchen space you will multiple 4.2 and 3 meters together and get 12.6 Meters, therefore 12.6 meters squared is the area of the kitchen floor.
