A rectangular piece of poster board measurea 60 centimeters by 80 centimeters. Linn draws the net of a box on the poster board a

Ganezh [65]

To find the answer for that question you have to find the area of rectangle first, so you say 60*80 which equals to 4800 cm squared and then find the area of the box and not its volume so you say: 2(16*10)=2*160=320 cm squared
4(16*27)=4*432=1728 cm squared
add 320+1728= 2048 cm squared
Finally, to find the area of the left poster board you have to subtract the area of the rectangle which is 4800 cm squared by the area of the box which is 2048 cm squared so 4800-2048=2752 cm squared

What is the vertex of g(x) = 3x2 − 12x + 7? (−6, −5) (−2, −5) (2, −5) (6, −5)

kupik [55]

(h ,k) —> (2 , –5)

g(x)=3x²-12x+7 —> y= 3(x-2)²-5

y=a(x–h)²+k —> a= 3 , h=2 , k= –5

(h ,k ) —> (2, –5)

I hope I helped you^_^

What is the value of xy over z if x =-2 y=-3 and z=4

Art [367]

$\dfrac{xy}{z};\ x=-2,\ y=-3,\ z=4$

Substitute the values of x, y and z to the expression:

$\dfrac{(-2)(-3)}{4}=\dfrac{6}{4}=\dfrac{6:2}{4:2}=\dfrac{3}{2}$

For my math it says someone ordered a poster with a height of 2 feet and width of 0.7 feet what is the area of the poster

Phantasy [73]

STEP-BY-STEP SOLUTION:

Let's solve this problem step-by-step.

As posters are generally rectangular in shape, we will establish the formula for the area of a rectangle which we will be using as displayed below:

Area = height × width

Now let's find the area of the postwr using the above formula.

Height = 2 feet

Width = 0.7 feet

Area = height × width

Area = 2 × 0.7

Area = 1.4 square feet

ANSWER:

Therefore, the answer is:

The area of the poster is 1.4 square feet.
