15/4 = 3 3/4

Step-by-step explanation:

15/4 = 3 R 3 = 3 3/4

Answer:

3 3/4

Step-by-step explanation:

Answer:

All the domains are x values (-8, -4, 1)

All the ranges are y values: (4, -4, -5)

Step-by-step explanation:

Given:

The distance flown was 135 km.

The average speed was 180 km/h.

To find:

The time taken by the airplane.

Solution:

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

[tex]Time=\dfrac{Distance}{Speed}[/tex]

Putting Distance = 135 and Speed = 180, we get

[tex]Time=\dfrac{135}{180}[/tex]

[tex]Time=0.75[/tex]

The time taken by the airplane is 0.75 hours.

We know that,

1 hour = 60 min

0.75 hour = 0.75 × 60 min

0.75 hour = 45 min

Therefore, the time taken by the airplane is 45 min.

Answer: 1.65

The cost of 1 lb of sugar candies is $1.65.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Explanation

Given to us

weight of candy mix = 100 lb,

weight of jelly beans = 100 lb,

Cost of jelly beans = 20 cent per lb = $0.20 per lb,

Cost of candy mix = $1.36 per lb.

Total cost of candy mix:

Total cost of candy mix = weight of candy mix *  Cost of candy mix

                                       = 100 lb * $1.36

Total cost of Jelly beans:

Total cost of Jelly beans = weight of Jelly beans *  Cost of Jelly beans

                                         = 20 lb*  $0.20

Weight of Sugar candies:

weight of Sugar candies = weight of candy mix - weight of jelly bean

                                        = 80 lb

Total cost of sugar candies:

Total cost of candy mix = Total cost of jelly beans + total cost of sugar candies

100 lb * $1.36 = 20 lb*  $0.20+ 80lb*x

solving we get,

x = 1.65

Hence, the cost of 1 lb of sugar candies is $1.65.

Answer:

y=-3x

Step-by-step explanation:

Easy!

4 units x 4 is

16

Answer:

Step-by-step explanation:

First, we need to find the hypotenuse, so we need to apply the equation from the Pythagorean Theorem

A^2+B^2=C^2.

We know A^2 and B^2, so we need to substitute that into the equation

2^2+4^2=C^2

so now, simplify.

4+16=C^2

20=C^2

Square root of 20 is about 4.5

so 4.5 is the length of the sides of the square.

4.5x4.5=20.25

Answer:

65 is x

Step-by-step explanation:

the equation is 2x+50=180 remember line measures 180 degrees that is why the equation also equal 180.

Answer:

x = 65

Step-by-step explanation:

The line is a 180 degree so 180- 50 = 130

130 / 2 = 65

2 x 65 = 130

X = 65

Answer: Statement A

Step-by-step explanation:

Answer:

17 + 15

Step-by-step explanation:

==========================================================

Explanation:

We have n = 8 sides for this octagon.

This means the interior angles sum to 180(n-2) = 180(8-2) = 180*6 = 1080 degrees.

The tickmarks tell us that each side is the same length, so we have a regular octagon. This means that all 8 angles are the same measure. Let's say each angle is y degrees.

1 angle = y degrees

8 angles = 8y degrees

Solving 8y = 1080 leads to y = 1080/8 = 135

Each angle of this regular octagon is 135 degrees.

--------------------

Now set 16x+23 equal to 135 and solve for x

16x+23 = 135

16x+23-23 = 135-23

16x = 112

16x/16 = 112/16

x = 7

Area of the rectangle = L X W

Area of the rectangle = 4 X 2

Area of the rectangle = 8 inches

If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.

So 8 inches X 5 = 40 inches is the actual area of the unit.
