Answer:

Step-by-step explanation:

x      - some integer

2x+1      - an odd integer (the smaller one)

2x+1+2=2x+3       - the next odd integer consecutive to 2x+1  (the larger)

2×(2x+1)       - twice the smaller number

2x+3+2•(2x+1)     -the sum of the larger number and twice the smaller number

4•(2x+1)      - four times the smaller number

4•(2x+1)-27     - 27 less then four times the smaller number

2x + 3 + 2•(2x + 1) = 4•(2x + 1) - 27

2x + 3 + 4x + 2 = 8x + 4 - 27

            6x + 5  =  8x - 23

                  -5            -5

              6x  =  8x - 28

             -8x       -8x

            -2x  =  - 28

          ÷(-2)      ÷(-2)

              x  = 14

2x+1 = 2•14 + 1 = 29

2x+3 = 2•14 + 3 = 31

Check:  31+2•29=31+58=89;  4•29-27=116-27=89

Answer: Polyhedron

Step-by-step explanation: A polyhedron is a shape, with 2 parts. Face and Edge, they can only be connected with a edge or a vertex. Only 5 regular polyhedrons exist; tetrahedron ~ 4 faced 'the cube' ~ 6 faced the octahedron ~ 8 faced ~ the dodecahedron ~ 12 faced, and the icosahedron ~ 20 faced.

Given parameters:

Mark up percentage  = 150%

Original cost = $488

Sales tax = 5%

Unknown:

His total cost  = ?

Solution:

Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.

 Since the emerald was marked up by 150%;

   New cost  = (1 + 1.5) x $488 = $1220

Now, the additional tax was 5%;

   Tax = [tex]\frac{5}{100}[/tex] x 1220 = $61

So, the total cost = New cost + tax  = $1220 + $61 = $1281

The equation of the line, in point-slope form, is: A. y - 1 = -2(x - 4).

Where, a and b are coordinates of a point on a line, and m is the slope, the equation of the line in point-slope form can be written as, y - b = m(x - a).

Given:

Therefore, substitute (a, b) = (4, 1) and m = -2 into y - b = m(x - a).

Thus:

y - 1 = -2(x - 4)

Therefore, the equation of the line, in point-slope form, is: A. y - 1 = -2(x - 4).

Answer:

C. arm span, foot length is predicted to increase by about 0.186 cm.

Step-by-step explanation:

edgen 2022

C) arm span and foot length are predicted to increase by about 0.186 cm.

Linear regression analysis is used to predict the value of a variable based on the value of another variable. The variable you want to predict is called the dependent variable. The variable you are using to predict the other variable's value is called the independent variable.

Given, The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in the scatterplot.

let "FL" be the foot length and "AS" be the Arm span.

Slope = Δy/Δx = ΔFL/ΔAS

ΔFL/ΔAS = 0.186

ΔFL = ΔAS* 0.186

thus an increase in AS by 1 cm will lead to an increase in FL by 0.186cm

Therefore,  the slope of the least-squares regression line means for each additional centimeter C) arm span, foot length is predicted to increase by about 0.186 cm.

Answer:

a = 3.09 m/s^2

Step-by-step explanation:

v^2 = Vo^2 +2ax

v= final velocity

Vo = initial velocity

a = acceleration

x = distance

(-10.9)^2 = (-27.7)^2 + 2(a)(-105)

118.81 = 767.29 - 210a

-210a = -648.48

a = 3.09 m/s^2

[tex]( {v})^{2} - ({v(0)} \: )^{2} = 2 \times a \times ∆x[/tex]

[tex]( { - 10.9})^{2} - ({ - 27.7})^{2} = 2 \times a \times - 105 \\ [/tex]

[tex]118.81 - 767.29 = - 210 \times a[/tex]

[tex] - 648.48 = - 210 \times a[/tex]

Negatives simplified :

[tex]648.48 = 210 \times a[/tex]

Divided both sides by 210 :

[tex]a = \frac{648.48}{210} \\ [/tex]

[tex]a = 3.088 \: \: \frac{m}{ {s}^{2} } \\ [/tex]

Answer:

Step-by-step explanation:

let sale be x

and his salary be y

y=300+0.4x----------1 the old equation

y=450+0.2x----------2 the new equation

for his salary to be the same

equation 1 and 2 must be equal hence

300+0.4x=450+0.2x

solving for x we have

300-450+0.4x-0.2x=0

-150+0.2x=0

0.2x=150

x=150/0.2

Answer:

Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting

Step-by-step explanation:

4 drops of food coloring to 2 cups of white frosting and get the orange frosting.

He has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add

Let x = drops of food coloring he will add

Drops of food coloring : cups of white frosting

4 : 2 = x : 5

4 / 2 = x / 5

Cross multiplication

4 * 5 = 2 * x

20 = 2x

Divide both sides by 2

x = 20 / 2

= 10

x = 10 drops of food coloring

Therefore, Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting

Answer:

5/8

Step-by-step explanation:

I believe this should be fraction addition (?)

3/8 + 1/4

8, 4: 8 = 3/8 + 2/8

= 3 + 2/8 = 5/8

You have a total of (5/8)th part of a complete pizza.

Given is that you have 3/8 of a pizza in one box and 1/4 in another box.

Assume that the total pizza you have is denoted by [x].

[x] = (3/8 + 1/4) of a pizza

[x] = (3 + 2)/8 of a pizza

[x] = 5/8 of a pizza

Therefore, you have a total of (5/8)th part of a complete pizza.
