Answer:

The ribbon is 28.4 meters

Step-by-step explanation:

Given the box is 5m high, 6m long, and 8m wide,

we have a right angled triangle with hypotenuse = unknown, x, say

Opposite = 5m and 8m

Then, by Pythagoras theorem

x² = 5² + 8²

x² = 25 + 64

x² = 89

x = √89 ≈ 9.4m

The ribbon is now (5 + 6 + 8 + 9.4)m = 28.4m

Which line has a slope of zero and goes through (5, -8)
goblinko [34]

Answer:

y=-8

Step-by-step explanation:

From the information given, we know that the slope of the line is 0. Let's make an equation in y=mx+b form with what we know.

y=0x+b

We also have a point on the line, (5, -8). We can plug these two numbers for x and y to find b and complete the equation. -8 goes in as y and 5 goes in as x.

-8=0(5)+b

Now just solve for b.

-8=0+b

b=-8

We now know that b is -8 and can complete the equation.

y=0x-8

y=-8

Which of the points plotted below satisfy the equation in the box? <br><br>Check all that apply.
coldgirl [10]
Im not 100% sure but, this is how I solved the problem. Just plug the coordinates into the equation. For example, (3,9) x=3 and y=9.
the equation is y=x*3 so 9=3*3 and 3*3=9 so that point is true. If you continue to do the same thing for all the point you should get F,C, and D

Owen’s parents were planning a birthday party for him. They have $20.00 to spend on goodie bags. They need to buy 6 goodie bags
Dimas [21]

Answer:

Yes, they can buy all the bags.

Step-by-step explanation:

Owen's parents need to buy 6 bags for $2.49 each.

So, we need to calculate the total price:

$2.49 * 6 = $14.94

Since the bags cost $14.94, and Owen's parents have $20.00, they have enough money to buy all 6 bags. 14.94 < 20.00

Hope this helps!
