Answer:

Quadratic

Step-by-step explanation:

Not adding or multiplying

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:

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:

$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

1=g

you want to first isolate the variables on one side. from there you calculate all the real numbers together. then you divide the number being multiplied with teh variable by the number that was calculated on the other side.

Once you have a singluar amount of the variable, you know you have your answer.

Answer:

Tanner

Step-by-step explanation:

6/8 = .75 tanner

2/5 = .4 heather

.75 > .4

Step-by-step explanation:

[tex]volume =\pi {r}^{2}h[/tex]

[tex]area = \pi {r}^{2} [/tex]

remember

[tex]\pi = 22 \div 7[/tex]

So, we will just place the area and equate it to the unknown volume including the height

1004.80 = 22/7 × 10× 10 × h

1004.80 = 314.26h

h = 3.197

the answer is between 11 and 12

Answer:

allen= y=3/2+2  billy= y= 3/2+4

Step-by-step explanation:

ok both of the equation are (almost) the same except for the y intercepts.

y=mx+b... you are learning about that hopefully!

so. each of their trees are growing by 3... feet I'll just say feet. that means the slope is three because they are each going up that much. you also have to pay attention to the fact that the year is going up by two, so your tree is actually growing by 1.5 (3 halves) feet each year. now you have to find the y intercept by back tracking. remember that the y intercept is where y is zero and x is whatever it is.

if you go back three on allen, the y intercept is 2 and if you go back on billy, the y intercept is 4.

as for the second question, the lines are parallel. they have the exact same slope so that means that they will never cross  because billy's line is higher then allens, billy's tree will always be higher

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

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:

A(an)   altitude    of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)

Step-by-step explanation:

AN ALTITUDE -  An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.

Hence , the answer is an altitude .
