Answer:

(125*2)/8=b

Step-by-step explanation:

The way to find the area of a triangle is to multiply height and width then divide by two and 125 is the area. Then that means 125=250/2.

Since the height is 8 we can make the equation (125*2)/8.

Hopefully that was helpful and made sense.

Answer:

You use the formulas for the shapes

Cylinder= 2×π×r×h+2×π×r²               π×r²×h

Cone= \pi*r(r+\sqrt{ h^{2} +r^{2}} )           π×r²×\frac{h}{3}

Square Prism= 2×a²+4×a×h                       a²×h

                            ↑a=base edge

Step-by-step explanation:

                           Surface Area  Volume

Cylinderical Head   ≈282.74                   ≈314.16  

Conical Hat                     ≈170.13                     ≈78.54

Right Cylinder Torso      ≈471.24                     ≈785.4  

Right Cylinder Arm         ≈56.55                      ≈25.13

Square Prism Leg           =224                           =192

Are the following expressions equivalent? Why or why not? <br> 6(2x + 4) and 12x + 24
MrMuchimi

Answer: Yes

Step-by-step explanation:

When using the distributive property, 6(2x + 4) becomes 12x + 24

6 * 2x = 12x and 6 * 4 = 24

12x + 24 = 12x + 24

Therefore, the expressions are equivalent.

Miyoko's goal is to earn more than \$950$950dollar sign, 950 this week. She earns \$250$250dollar sign, 250 for every day she wo
GrogVix [38]

$250 c+ $ 180 g > $ 950

<u>Step-by-step explanation:</u>

As a cryptographer (c), Miyoko earns per day = $ 250

As a geologist (g) , Miyoko earns per day = $ 180

So the equation comes to be $250 c+ $ 180 g = $ 950

The equation can be rewritten to find c as, (950-180 g) / 250

The equation can be rewritten to find g as, (950 - 250 c) / 180

Plugin different values of c and g in the above 2 equations, we can find that ,

To achieve the goal, Miyoko requires to be a geologist for 3 days and crpytographist for 2 days.
