Answer:

4/15 was left over from is salary.

Step-by-step explanation:

Common denominator is 15. 5/15+6/15= 11/15.

15/15-11/15= 4/15.

If Mr Hassan spent 1/3 of his salary on food and 2/5 of the remainder on transport then 4/15  fraction of his salary was left.

A fraction represents a part of a whole.

Let us consider the salary of Hassan as 1.

Mr Hassan spent 1/3 of his salary on food

2/5 of the salary on transport.

We need to find the fraction of his salary left.

We need to subtract 1/3 and 2/5 from 1

1-1/3-2/5

LCM of 3 and 5 is 15

15-5-6/15

4/15

Hence, 4/15 is the fraction of Hassan salary was left

Answer:

The average speed of the athlete for the entire competition is approximately 21.23 km/hr

Step-by-step explanation:

The given parameters of the athlete performance in the triathlon are;

The length the athlete swims = 750 m = 0.75 km

The time the athletes spends swimming = 15 minutes = 0.25 hours

The speed with which the athlete cycles = 40 km/hr.

The time the athletes spends while cycling = 30 minutes = 0.5 hours

The distance the athlete ran = 5 km

The average speed with which the athlete ran = 3 m/s = 10.8 km/hr.

The formula for average speed, s is Average speed = Total distance/(Total time)

The distance, ∑d, the athlete covered in the entire competition is given as follows;

∑d = 0.75 km + 0.5 hr. × 40 km/hr. + 5 km = 0.75 km + 20 km + 5 km = 25.75 km

The distance, ∑t, the athlete spends in the entire competition is given as follows;

∑t = 0.25 hr. + 0.5 hr. + 5 km/(10.8 km/hr.) = 0.25 hr. + 0.5 hr. + 0.463 hr. ≈ 1.213 hr.;

Therefore;

The average speed of the athlete for the entire competition, s = ∑d/∑t = 25.75 km/(1.213 hr.) ≈ 21.23 km/hr.

Answer:

a. 10 + 2.50x

b. 60

c. 100

Step-by-step explanation:

a. 10 + 2.50x

b. 10 + 2.50(20)

= 10 + 50

= 60

c. 260 = 10 + 2.50x

250 = 2.50x

250/2.50 = x

x = 100

Answer: The number 12 represents admission charge in Mariana's equation.

Step-by-step explanation:

As per given ,

Total cost = ( Charge per ticket) (Number of tickets) +  (Admission fees)  (i)

For x = Number of tickets, the total cost (c) for a day at the amusement park is given as

[tex]c = 1.50x + 12[/tex]                                       (ii)

Here, 12 = Admission fees                 [Comparing (i) and (ii)]

Hence, the number 12 represents admission charge in Mariana's equation.

Answer:

Length is 32. 6 cm and width is 5.9 cm

Step-by-step explanation:

width(w)=w

perimeter(p)=78 cm

length(L) = 4w+9

p=2L+2w

78=2(4w+9)+2w

78=8w + 19 + 2w

10w=59

w=5.9 cm

L=4w+9

L=4(5.9)+9

L=32.6 cm

Therefore length is 32.6 cm and width is 5.9 cm

Answer:

(-2, -12), (0, 2), (2, 16), (4, 30)

Step-by-step explanation:

Input: -2

y = 7x + 2

y = 7(-2) + 2

y = -14 + 2

y = -12 (Output)

Input: 0

y = 7x + 2

y = 7(0) + 2

y = 0 + 2

y = 2 (Output)

Input : 2

y = 7x + 2

y = 7(2) + 2

y = 14 + 2

y = 16 (Output)

Input: 4

y = 7x + 2

y = 7(4) + 2

y = 28 + 2

y = 30 (Output)

Answer:

Step-by-step explanation:

7(2)³ - 2(2)² + 4(2) - 5 = 51

The answer is (D).

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The value of x and y is 1 and -3.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4y = 6 is an equation.

2x = 4 is an equation.

4x - 6x + 6x = 6 is an equation.

We have,

x - y = 4 _____(1)

4x + y = 1 _____(2)

From (1) we get,

x = 4 + y ____(3)

Putting (3) in (2) we get,

4x + y = 1

4 (4 + y) + y = 1

16 + 4y + y = 1

16 + 5y = 1

Subtract 16 on both sides.

5y = 1 - 16

5y = -15

Divide both sides by 5.

y = -3

Now,

Putting y = -3 in (3) we get,

x = 4 + y

x = 4 - 3

x = 1

Thus,

The value of x and y is 1 and -3.

Answer:

500x^11

Step-by-step explanation:

Using PEMDAS first get rid of parenthesis

(2x^4)^2 is the same as 2x^4 * 2x^4 or 4x^8

(5x)^3 is the same as 5^3 * x^3 or 125x^3

multiply the two together, remember exponents on like terms add together

125*4 = 500

x^8 * x^3 = x^11

multiply together

500x^11

I can do a and b for you but im unsure about c and d. I'm sorry :((

a. x = 2  

It is the only point that hits the x axis, thus making it a zero of f(x).

b. substitute 2 for x in the original equation and it should equal 0.

f(x)= x^3 - 2x - 4

f(x)= 2^3 - 2(2) -4

f(x)= 8 - 4 - 4

f(x)= 0
