Answer:

240

Step-by-step explanation:

Step 1 : Prime factorize the given terms.

Step 2 : Out of the factors of all terms, take the factors with the highest power of different bases and multiply.

⇒ LCM (24, 15, 16) = 2⁴ x 3 x 5

⇒ LCM = 16 x 15

⇒ LCM = 240

The complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)

The expression is given as:

9x² + 3x - 2

Expand the equation

9x² + 3x - 2 = 9x² + 6x - 3x - 2

Factorize the expression

9x² + 3x - 2 = 3x(3x + 2) - 1(3x + 2)

Factor out 3x + 2

9x² + 3x - 2 = (3x - 1)(3x + 2)

Hence, the complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)

Answer:

4:25

Step-by-step explanation:

Sphere surface area = 4 pi r^2  

   now change r to 2.5 r  ( to maintain the 2:5 ratio)

   area2 = 4 pi (2.5 r)^2 =     6.25    *    4 pi r^2

    so ratio of surface areas is  1 : 6.25   = 4:25

If two similar spheres have a scale factor of 2:5. Then the ratio of their surface areas will be 4 / 25.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Two similar spheres have a scale factor of 2:5.

Let the r₁ and r₂ be the radius of the spheres. Then we have

r₁ / r₂ = 2 / 5

Then the surface area of the sphere is given as

Surface area = 4πr²

Then the ratio of their surface areas will be

[tex]\rightarrow \dfrac{4\pi r_1^2 }{4\pi r_2^2} = \left (\dfrac{r_1}{r_2} \right )^2[/tex]

Then we have

→ (2 / 5)²

→ 4 / 25

Answer:

Line graph

Step-by-step explanation:

A line graph is specifically used to display data that changes over time, a line plot uses several points connected by straight lines on an x and y axis.

I wouldn't choose a histogram because a histogram is used to summarize continuous data.

As well as I wouldn't use a circle graph becasue it is often used to show the percentage of of population who gave a certain answer.

Answer:

Step-by-step explanation:

Since a sprinkler rotates 90°, pauses,and then rotates another 90°

So, here total degrees be like

= 180°

hence, The number of degrees did it rotate altogether should be considered as the 180 degrees.

Answer:

$5745.03

Step-by-step explanation:

A = 4250(1 + 0.044)7 = $5745.03

The required amount in the Mai accounts after 7 years will be $5745.03.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Amount = principal[1 + r/n]ⁿᵃ

Here,

Principal = 4250, rate = 4.4%, Time = 7 ,
Amount = 4250[1 + 0.044]⁷
Amount = $5745.03

Thus, the required amount in the Mai accounts after 7 years will be $5745.03.

Answer:  Janet's overtime pay is: " $ 17. 19 per hour ."
  →  and specifically:  " $ 77.36 " ;
        →  [for the 4.5 hours of overtime pay worked Within the total 44.5 hours Janet worked within the particular Monday to Friday workweek as given within this particular Brainly question/].
__________

Step-by-step explanation:
__________
Note:  Let us assume that up to and including "40 hours within a workweek" is paid as a "base rate of regular pay"—and that any hours worked over "40 hours" count as "overtime hours.."

Furthermore: Let us assume that "overtime pay" is paid at the rate of "time and a half".  This means that any and all hours worked over 40 hours are "overtime hours"—and that these "overtime hours" are paid at the rate at "1.5 times" the rate of the regular hourly rate.
__________

Note: A secretary is typically a job that is paid by the "hour"; as opposed to certain management positions (which are paid by "salary").
→ So, we shall assume that the secretary, "Janet Henderson", is a "hourly worker"—who is "non-exempt" from being paid "overtime."
→ So, first, given:  Janet Henderson worked Monday through Friday for a total of "44.5 hours."
Note: This amount: "44.5 hours" ; is over "40 hours."
            {i.e. " [44.5 hours]  >  [40 hours] ".}.

Note:  Any and all hours Janet earned in excess of 40 hours are considered : "overtime hours."
Now:  Let us calculate the number of "overtime hours":
   → We subtract: "40"; from the actual amount of hours Janet worked [which is "44.5 hours"] ;
    →   " (44.5 − 40) hours " ;
          =  " 4.5 hours " (of overtime worked).
Now, we are given that Janet's regular pay is:  " $ 11.46 per hour."
→  To solve: Find the value of:   " (1.5) * ($ 11.46) " ;
Method 1) Use a calculator:  to get:  " 17. 19 " .
    → The answer is:  " $ 17.19 per hour."

Method 2)
    →  " 11.46 + [(1/2)* 11.46] " ;

             =  "11.46 + (11.46 /2)" ;  
Note: Let us start by calculating:  "(11.46 / 2)" ; that is:  "(11.46 ÷ 2)" .
Method A) Note:  " 11.46 ÷ 2 = 5.73 " ; → {Using a calculator.}.
Method B)  
Using long division; to get:  "5.73 " ; as follows:

            5.73
      2⟌ 11.46

        - 10    
             1.46
        -    1.4  
             0.06
        -    0.06
             0.00 .

Now:  We can write the expression:  
 →   " 11.46 + [(1/2)* 11.46] " ;  as:
 →     " 11.46 + 5.73 " ; & then calculate (add the values);

to get" 11.46 + 5.73 = " 17. 19 "

So;  Janet's overtime pay is $17.19 per hour.

Other:
To find the specific, exact dollar amount of overtime pay earned for the "4.5 hours" of overtime worked in the particular Monday to Friday workweek as given within the actual question:

→ We multiply this amount—"17.19 dollars"— by the number of overtime hours that Janet worked—"4.5 hours"—as follows:
→  "   [tex]\frac{17.19 dollars}{hr} *\frac{4.5 hr}{1}[/tex]  " ;  
→  The units of "hr" ["hour(s)"] cancel out to: "1 ";  
          →  {since:   ["hr/ hr " = 1 .] } ;
And we have:  
→ " (17.19 dollars * 4.5)  = _?  dollars " ;  Solve for: {the "_?_"  value.}:
Using a caculator:  We get:
   →  77.355 dollars;  ⇒  write as:  $77.355 ;  round to:  " $ 77.36 " .

Answer:

  72 cubic yards

Step-by-step explanation:

The volume of a prism is given by ...

  V = Bh

where B is the area of the base, and h is the distance between bases.

Here, the base is a triangle, so its area is given by ...

  A = 1/2bh

where b is the base of the triangle, and h is the height perpendicular to the base.

__

Using these formulas with the dimensions given, we have ...

  B = 1/2(8 yd)(3 yd) = 12 yd²

  V = (12 yd²)(6 yd) = 72 yd³

The volume of the triangular prism is 72 cubic yards.

_____

Additional comment

Effectively, the volume of a triangular prism is half the volume of a rectangular prism with the same length, width, and height.
