Answer:

d. 23

Step-by-step explanation:

Let the number of cars be x and buses be y

<u>Then we have below inequalities as per given:</u>

5x + 32y ≤ 1310
x + y ≤ 135

It is easy to notice that cars occupy 6 times less area than buses but cost of parking is 3 times less. So we would need maximum number of cars and minimum number of buses to maximize income

<u>Let's assume there are 135 cars and buses, then from the second inequality:</u>

x = 135 - y

<u>Substitute it in the first one:</u>

5(135 - y) + 32y ≤ 1310
675 - 5y + 32y ≤ 1310
27y ≤ 1310 - 675
27y ≤ 635
y ≤ 635/27
y≤ 23.5

The greatest number of buses is 23

Option D. 23 is correct

If line segment ab=7cm draw a perpendicular at a point c on line ab such the ac=3.5cm

Reil [10]

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm

<h3>How to draw the perpendicular at a point c on line ab such the ac = 3.5 cm?</h3>

The given parameters are:

Length of segment AB = 7 cm

Also, we have:

Point C is located on line segment AB

This means that:

Length of segment AC = Length of segment BC = 3.5 cm

When represented on a line segment, we have:

A C B

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm

Given a container that is 4.50 ft. by 7.20 ft. that is filled with water 5.00 inches deep.What is the volume of water in liters

elena55 [62]

Answer:

382.3 liters

Step-by-step explanation:

We are told in the question that:

A container that is 4.50 ft. by 7.20 ft. that is filled with water 5.00 inches deep.

This means:

Length = 4.50 ft

Width = 7.20 ft

Depth(Height) = 5.00 inches

We have to convert all of these to centimeters first. Then to liters

1 foot = 30.48 centimetres

1 inch = 2.54 centimetres

Length = 4.50 ft

1 foot = 30.48 centimetres

4.5 ft = 4.5 × 30.48

= 137.16 cm

Width = 7.20 ft

1 foot = 30.48 centimetres

7.20 ft = 7.20 × 30.48 cm

= 219.456cm

Depth(Height) = 5.00 inches

1 inch = 2.54 centimetres

5 inches = x cm

Cross Multiply

= 5 × 2.54 cm

= 12.7 cm

The volume of the water(cm³) = Length × Width × Depth

= (137.16 × 219.456 × 12.7)cm³

382277.428992 cm³

The volume of water in liters

1 cubic centimetre = 0.001 litre

382277.428992 cm³ = x

Cross Multiply

382277.428992 cm³ × 0.001 litre

= 382.2774289920001 liters

Approximately = 382.3 liters

If Y is between X and Z, then X, Y, and Z are collinear?

gtnhenbr [62]

I think, I'd go with A) Always true. As 2 points is always the line. If you add third one, it will be collinear.

(Please help) Which answer describes the polynomial?

lbvjy [14]

$\bf 3x^3+4x^2-7\quad 
\begin{cases}
3x^3\impliedby &3rd~degree\\
4x^2\impliedby &2nd~degree\\
7\impliedby &0~degree
\end{cases}$

notice, there are three terms, therefore is a trinomial.

the term that has the highest degree, has a degree of 3, therefore the degree of the polynomial as a whole is 3, or a cubic degree.

so, is a cubic trinomial.
