Answer:

$55.42

Step-by-step explanation:

Price of supplies = 100%

Percentage of tax = 8.25%

Total percentage = 108.25%

Amount allowed to spend = $60

108.25% = 60

60 / 108.25 = .55427

0.55427x100 = 55.427

Round down

$55.42

Answer:

d < -7

Step-by-step explanation:

-38d - 57 > -19d + 76

Add 19d to both sides

-19d - 57 > 76

Add 57 to both sides

-19d > 133

Divide both sides by -19

(when multiplying or dividing by a negative the inequality is reversed)

d < -7

Answer:

d < -7

Step-by-step explanation:

-38d - 57 > -19d +76

Add 19d and 57 to both sides

-19d > 133

Divide both sides by -19 (dividing by negative flips the inequality sign)

d < -7

Answer:

LH: 5 x 7 = 35 m²

LW: 5 x 4 = 20 m²

WH: 4 x 7 = 28 m²

Add and Double: 35 + 20 + 28 = 83 m², 83 x 2 = 166 m²

Surface Area: 166 m²

Answer:

C) 17

Step-by-step explanation:

Using the rule

A^2 + B^2 = C^2

8^2 + 15^2 = x^2

64 + 225 = x^2

x^2 = 289

x= _/-289

x = 17

Answer:

The perimeter of the figure is approximately 42.85.

Step-by-step explanation:

Based on the given values, you already know that two of the sides of the shape are 12 units long. Since the half-circle above the rectangle is the same size as the gap in the rectangle - you know this because both of the half-circle's diameter are 6 units long - so you can add 24 units to the perimeter of a circle with a diameter of 6. The diameter of the circle is [tex]6\pi[/tex], or approximately 18.85, so the perimeter of the whole figure is approximately 42.85.

Answer:

Part A

The motion of an elevator in a building is mechanically controlled by electrical powered devices and therefore, the motion of an elevator between start and stop is uniform motion without acceleration and therefore, a person in a moving elevator will not experience a force, therefore a blindfolded person will believe that the elevator is not moving at all

Part B

Yes the person can tell when the elevator begins or stops

When the elevator begins moving, the velocity increases from zero at a rate and the blindfolded person will be able to sense the ground moving further lower under their feet making them feel lighter

Similarly, when the elevator slows down to stop, the initial downward velocity of the elevator is steadily reduced as the elevator decelerates. The blindfolded person will be able to sense the slowing down (braking) of the elevator experiencing an increased upward force from the floor of the elevator, with the feeling of slightly increased weight

Answer: 38

Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6

Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12

Two equal sides are 13 and base 12

Perimeter is 13 + 13 + 12 = 38 units

Answer is: 38

The perimeter of the given isosceles triangle is 38 cm.

The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;

We can say that the perimeter of an isosceles triangle is:

P = 2a + b

where;

3x - 5 =  19 - x

3x + x = 19 + 5

4x = 24

x = 24/4

x = 6

The perimeter of the isosceles triangle is:

= 3x - 5 + 19 - x + 2x

= 3(6) - 5 + 19 - 6 + 2(6)

= 18 + 8 + 12

= 38 cm
