Chris took a vacation trip to maine, where sales tax on taxable items is 5%. in maine, prepared food and lodging are taxed an ad
12345 [234]
So, it's just an annoying problem. Keep the tax rates in mind for each thing.
$70 of souvenirs mean the tax is 5% since it is not prepared food, lodging, or auto rentals.
$580 on prepared food means that has 7% tax because it is special.
$620 on the car has a 10% tax, as stated in the problem.
So do 70(1.05)+580(1.07)+620(1.1) to get $1376.1.0

a 10 foot ladder is leaning against the wall. the bottom of the ladder is 4ft from the base of the wall. which of the following
Pie

Answer:

The height of the wall is 9.17ft

Step-by-step explanation:

The length of the ladder is 10ft

Distance from the foot of the ladder to the wall is 4ft

The height of ladder is unknown.

To solve this question, you'll require a pictorial illustration of the situation. Kindly check attached document for that.

Since it's a right angle triangle, we have two sides with one sides unknown, we can use pythagorean theorem to find the third side.

The hypothenus (x) is 10ft

The adjacent is (y) 4 ft

The opposite (z) (height of the wall) is unknown.

X² = Y² + Z²

10² = 4² + Z²

100 = 16 + Z²

Z² = 100 - 16

Z² = 84

Z = √(84)

Z = 9.165 = 9.17ft

The height of the wall is 9.17ft

Lapatulllka [165]

Step-by-step explanation:

1) -5n+10n

= 5n

2) -x-9+2x-10

= 2x-x-9-10

= x-19

3) -5(x-10)-x

= -5x+50-x

= -6x+50

4) 9-5(1-7x)

= 9-5+35x

= 35x+4

5) y^2-x

= 3^2-2

= 9-2

= 7

Do the remain questions by yourself, you can do it!
