The following examples have a unit rate of 30 meters per second:

B) 90 meters in 3 seconds.

D) 150 meters in 5 seconds.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

We have the unit rate of 30 meters per second.

A) 90 meters in 5 seconds.

The unit rate = 90/5 meters per second.

The unit rate = 18 meters per second.

B) 90 meters in 3 seconds.

The unit rate = 30 meters per second.

C) 120 meters in 6 seconds.

The unit rate = 20 meters per second.

D) 150 meters in 5 seconds.

The unit rate = 30 meters per second.

E) 240 meters in 6 seconds.

The unit rate = 40 meters per second.

Therefore, B and D have the unit rate of 30 meter per second.

Answer:

Step-by-step explanation:

Answer:

x= 2

z = 106

Step-by-step explanation:

By the definition of vertically opposite angles,

(10x + 54)° = 74° [Pair of opposite angles made by two intersecting lines]

10x = 74 - 54

10x = 20

x = 2

z° + 74° = 180° [Pair of supplementary angles]

z = 180 - 74

z = 106

Answer:

[tex](a)\ x = 0.4\ or\ (d)\ x = -2.7[/tex]

Step-by-step explanation:

Given

[tex]f(x) = -x^2 - 2x +6[/tex]

[tex]g(x) = 2x^2 + 5x + 3[/tex]

Required

Find x if [tex]f(x) = g(x)[/tex]

The above implies that:

[tex]-x^2 -2x +6 = 2x^2 + 5x +3[/tex]

Collect like terms

[tex]2x^2 + x^2 + 5x + 2x + 3 - 6 = 0[/tex]

[tex]3x^2 + 7x - 3 = 0[/tex]

Using quadratic formula, we have;

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where

[tex]a=3; b=7; c=-3[/tex]

[tex]x = \frac{-7 \± \sqrt{7^2 - 4*3*-3}}{2*3}[/tex]

[tex]x = \frac{-7 \± \sqrt{49+ 36}}{6}[/tex]

[tex]x = \frac{-7 \± \sqrt{85}}{6}[/tex]

[tex]x = \frac{-7 \± 9.22}{6}[/tex]

Split

[tex]x = \frac{-7 + 9.22}{6}\ or\ x = \frac{-7 - 9.22}{6}[/tex]

[tex]x = \frac{2.22}{6}\ or\ x = \frac{-16.22}{6}[/tex]

[tex]x = 0.4\ or\ x = -2.7[/tex] --- approximated

Step-by-step explanation:

The relative frequency that a randomly selected student's favorite exhibit was either butterflies or trains is 0.025.

Assume you need to compute the joint relative frequency of a certain category inside a larger category.

Then there's the proportion of that specific category's frequency to the total frequency of that large category.

The sum of all the frequency of the survey is;

⇒12+25+17+6

⇒60

The relative frequency for butterflies:

⇒12/60

⇒1/5

⇒0.25

The relative frequency for the train:

⇒6/60

⇒1/10

⇒0.1

The relative frequency that a randomly selected student's favorite exhibit was either butterflies or trains is;

⇒0.25×0.1

⇒0.025

Hence the relative frequency that a randomly selected student's favorite exhibit was either butterflies or trains is 0.025.

Answer:

Hatim=37kg, Fatin=31

Step-by-step explanation:

Hatim=x, Fatin=x-x

x+x-6=68

add 6 to both sides

x+x=74

2x=74

divide both sides by 2

x=37

put in 37 fo the values determined earlier

Hatim=37, Fatin=37-6

Hatim=37, Fatin=31

check by plugging in the values

37+31=68 (or 37+37-6=68, either one works)

Answer:

A

Step-by-step explanation:

Flat fee is $20 [initial cost]

Each bucket of ball is $5.75

b is the number of buckets and c is the total cost

To get total cost, we add the flat fee with the bucket fee. Bucket fee is $5.75 multiplied by the number of buckets, which is b.

So, we have:

cost = $20 + $5.75b

In equation it is:    

Choice A is right.

Answer:

k = constant of proportionality = 1/25

Step-by-step explanation:

Let

Amount of commission = x

Sales = y

Amount of commission she earns is directly proportional to the sales

x = k * y

Where,

k = constant of proportionality

what is the constant of proportionality of Yoshi sales commission

x = k * y

x = $8

y = $200

x = k * y

8 = k * 200

8 = 200k

k = 8/200

k = 1/25

k = constant of proportionality = 1/25

Answer:

Total length of fabric pieces is 8400 mm.

Step-by-step explanation:

Eva buys a piece of red fabric of length = 5.6 meters

Since, 1 meter = 1000 mm

Therefor, 5.6 meter = 5.6 × 1000

                                 = 5600 mm

Similarly, length of yellow fabric piece = 2.8 meters

                                                                ≈ 2.8 × 1000 mm

                                                                ≈ 2800 mm

If these pieces are joined together, total length of the fabric pieces

= 5600 + 2800

= 8400 mm

Therefore, total length of fabric pieces is 8400 mm.

Function A

Step-by-step explanation:

Given

[tex]A:\ y = 4x + 3[/tex]

[tex]B:\ y = \frac{1}{2}x + 5[/tex]

See attachment for complete question

Required

Which has a greater rate of change

A function is represented as:

[tex]y = mx + b[/tex]

Where

m is the rate of change

So, the rate of functions of A and B is

[tex]A:\ y = 4x + 3[/tex]

[tex]m_A = 4[/tex]

[tex]B:\ y = \frac{1}{2}x + 5[/tex]

[tex]m_B = \frac{1}{2}[/tex]

By comparison

[tex]m_A > m_B[/tex]

i.e.

[tex]4 > \frac{1}{2}[/tex]

Hence, function A has a greater rate of change
