Answer:

Part A: $12.325

Part B: $20.565

Step-by-step explanation:

To find the answer, we multiply 2.9 and 4.25 together: 2.9 * 4.25 = 12.325

The cost of 2.9 pounds of dark chocolate is $12.325

<u>PART B:</u>

To find the answer, we multiply 1.6 and 5.15 together: 1.6 * 5.15 = 8.24

After that, to find the cost of the dark and milk chocolate together, we add up the two answers: 12.325 + 8.24 = 20.565

The total cost of the milk and dark chocolate is $20.565

Note: <em>You might need to round it up. In this case, Part A is $12.33 and Part B is $20.57</em>

Step-by-step explanation:

Let grandson's age be x.

Let grandpa's age be y {equation : y = 8+5x}

so,

x + y = 88

or, x + 8+ 5x = 88 (substituting the value of y)

or, 6x + 8 =88

or, 6x = 88-8

or, 6x = 80

or, x = 80/6

so, x = 13.33

so grandson's age = 13.33

grandpa's age = 8 + 5x = 8 + (5×13.33) = 74.65 yrs

Question:Find the area of he trapezoid by decomposing it into other shapes.

Ad libitum [116K]

Answer:

D) 171 cm²

Step-by-step explanation:

You don’t actually need to decompose it. You could just do it as a trapezoid:

(15+23)/2=19

19x9=171

If you want to decompose it into 2 triangles and a rectangle:

10=15x9=135

1/2(3)(9)=13.5

1/2(5)(9)=22.5

135+13.5+22.5=171 also

A software designer is mapping the streets for a new racing game. all of the streets are depicted as either perpendicular or par

ElenaW [278]

The equation of the central street PQ is -1.5x - 3.5y = -31.5 option (b) is correct.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

We have a straight line:

$-7x+3y=-21.5$

Convert it to the general form given below:

$\rm y=mx+c$

$\rm 3y=-21.5+7x\\\\ \rm y = \frac{-21.5}{3}+\frac{7}{3}x$ or

$\rm y = \frac{7}{3}x-\frac{21.5}{3}$

$m = \frac{7}{3}$ (Slope of AB line)

For the slope(m') of the PQ line:

$\rm m'=-\frac{1}{m}$ ( because AB and PQ are perpendicular to each other)

$\rm m' = -\frac{3}{7}$

We know the:

$\rm (y-y')=m'(x-x')$

Where (x', y') = (7, 6), we get:

$\rm (y-6)=-\frac{3}{7} (x-7)$

$\rm 7(y-6)=-3 (x-7)\\\\\rm 7y-42= -3x+21\\\\\rm 7y= -3x+21+42\\\\\rm 3x+7y=63$

$\rm -1.5x-3.5y=-31.5$ (multiply by -1/2 on both sides)

Thus, the equation of the central street PQ is -1.5x - 3.5y = -31.5
