Answer:

Angle DCB is Equal to 78

Step-by-step explanation:

4x+2 + 3x+3 =180

7x +5=180

7x=175

x=25.

Then put the x in the 3x+3

3(25) +3 = 78

so  DCB = 78

Answer:

16

Step-by-step explanation:

The equation is X2 – 19x + 48 = 0

Using the quadratic formula

X= - b +- √ ( b^2 - 4ac)/ 2a

Where a= 1 b= -19 c= 48

Substitute into the formula we have

Answer:

  $2450

Step-by-step explanation:

Understand the function gives you the profit when x is the number of meals. You are asked for the profit for 50 meals. You solve it by evaluating the function with x=50.

  P = -2(50²) +152(50) -150

  P = -5000 +7600 -150

  P = 2450

Amelia will make $2450 in profit when she caters 50 meals.

Answer:

1. What would be the total weight, in pounds, of 10 small boxes and 15 large boxes?

What you do is 10 * 35 + 15 * 65 = 350 + 975 = 1325 pounds

2. What would be the total weight, in pounds, of s small boxes and I large boxes?

35s + 65l would be the total weight

Step-by-step explanation:

Answer:

Step-by-step explanation:

100 = -16t^2 + 92t

16t^2-92t + 100 = 0

4t^2 - 23t + 25 = 0

t = [23 ±√(23^2-4(4)(25))]/[2(8)] ≈ 1.5, 4.3

The rocket has altitude of 100 ft at 1.5 sec and 4.3 sec.

:::::

0 = 16t^2-92t = t(16t-92)

t = 0, 5.75

Rocket is in the air for 5.75 seconds

Frequency table for the height of the seedlings,

Height (in inches)        Number of seedlings

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

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

          [tex]\frac{5}{8}[/tex]                                      2

          [tex]\frac{7}{8}[/tex]                                      2

Now we can draw the line plot as attached.

Average height of the seedlings = [tex]\frac{2(\frac{1}{2})+4(\frac{3}{4})+2(\frac{5}{8})+2(\frac{7}{8})}{2+4+2+2}[/tex]

                                                      = [tex]\frac{1+3+1.25+1.75}{10}[/tex]

                                                      = [tex]\frac{7}{10}[/tex]

Answer:

K= 11

Step-by-step explanation:

You solve for K by subtracting 14 by 25.

25-14= 11

When k is pluged into k[tex]\geq[/tex] 11 the statement is true because it is equal to 11.

When plugged into k+14[tex]\geq[/tex]25;

11+14 =25.

That statement is also true because 25 is equel to 25.

Answer:

the scale factor is times 0.5

Explanation:

construction = divide the figure into two parts.

now we have triangle abd and bdc.

first calculate the area of abd.

area of triangle= 1/2×base ×height

area of triangle= 1/2×18×7.5

area of triangle=67.5cm²

second calculate area of bdc

area of triangle=1/2×15.6×11.7

area of triangle=91.26cm²

area of the figure=area of abd + area of bdc

area of the figure=67.5cm²+ 91.26cm²

area of figure=158.76 cm².

Answer:

  x = 2 m

  y = 30°

Step-by-step explanation:

The side lengths of ΔDEF are 3/9 = 1/3 of those of ΔABC.

  x = DF = 1/3(AB) = (1/3)(6 m)

  x = 2 m

__

Angle measures of ΔDEF are the same as those of the corresponding angles of ΔABC.

  y = ∠B = ∠E = 30°

  y = 30°

Ava: 3 / .83 = 3.6 MPH

Answer:

Maura.

Step-by-step explanation:

Maura:

5 miles/1.25 hours = 4 mph

Ava:

3 miles/(.83 hours) = 3.61 mph

Maura ran faster.

Answer:

B:  13.5 in^2

Step-by-step explanation:

The average length of this trapezoid is (4 in + 5 in)/2, or 4.5 in.

The height is 3 in.

Thus, the area is A = (average length)(height) = (4.5 in)(3 in) = 13.5 in^2
