Answer:

$1116

Step-by-step explanation:

Given data

We are told that the exchange rate is

£1=$1.55

if chris has £720

then £1 is the same as $1.55

      £720 will be x

cross multiply

x= 720*1.55

x= $1116

Answer:

2x + 5y +z²

Step-by-step explanation:

you multiply 2 and x then y and five and z and z

Answer:

x = 3

x = 4.5

Step-by-step explanation:

A) 2(5x - 3) = 24

5x - 3 = 12 (divide both sides by 2)

5x = 15 (add 3 to both sides)

x = 3 (divide both sides by 5)

B) 5(2x + 1) = 50

2x + 1 = 10 (divide both sides by 5)

2x = 9 (take 1 away from both sides)

x = 4.5 (divide each side by 2)

Answer:

A. Proportional by $30

B. 3 represents the hours he works

    90 represents the money he earned

C. $300

D. I don know, sorry

Step-by-step explanation:

The relationship is linear, the point (3, 90) represents in 3 hours he earns 90 dollars, in 10 hours, he earns 300 dollars, and the linear equation is y = 30x.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

This graph shows the relationship between x, the number of hours Mr. David works, and y, the number of dollars he earns.

A. Based on the graph, the relationship between x and y proportional is a linear relationship.

B. The point (3,90) represents in 3 hours he earns 90 dollars.

D. The linear equation will be

[tex]\begin{aligned} \rm y - 30 &= \rm \dfrac{90-30}{3-1} (x - 1)\\\\\rm y - 30 &= \rm 30x - 30\\\\\rm y &= \rm 30x \end{aligned}[/tex]

C. Based on the graph, the amount of money in dollars will Mr. David earn if he works 10 hours will be

y = 30x

y = 30 × 10

y = $300

Answer: $539

Step-by-step explanation:

From the question, we are informed that Mr Tyler bought 4 round-trip tickets from Florida to Canada and that the total cost is $2,156.

The cost of each ticket will then be:

= Total cost of the tickets / Number of tickets

= $2156 / 4

= $539

Therefore, each ticket cost $539

Answer:

4. x = 5

Step-by-step explanation:

For two lines to be parallel they must have the same slope, but not be the same line. Both x=3 and x=5 both have slopes of 0, so they are parallel. Another way to tell is that x=3 is a vertical line; therefore, it will be parallel to any other vertical line, such as x=5.

Answer2.58

Step-by-step explanation:

129 / 50 = 2.58

Step-by-step explanation:

[tex] \sin(a) = \frac{7}{25} = 0.28 \\ \sin(b) = \frac{24}{25} = 0.96 \\ \cos(a) = \frac{24}{25} = 0.96 \\ \cos(b) = \frac{7}{25} = 0.28 [/tex]

tan(A)= 7/24= 0.29

tan(B)= 24/7=3.42

A=16.26°

B=73.73°

Answer:

18.6%

Step-by-step explanation:

What is the percentage population increase if in 2001 it is 430000 and in 2011 it is 510000

Percentage increase is calculated as:

Final value - Initial value/ Initial value × 100

Final value = 510000

Initial value = 430000

Percentage Increase =

510000 - 430000/430000 × 100

= 80000 / 430000 × 100

= 0.1860465116 × 100

= 18.604651163 %

Approximately = 18.6 %

Answer:

25/4 or 6.25

Step-by-step explanation:

Given that the general equation of  a quadratic equation is given as

ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.

Hence given x^2-5x-19=0, to complete the square, we add

(-5/2)^2 to both sides following the illustration given.

This is 25/4 or 6.24

Step-by-step explanation:

Answer:

$50820

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 38500 × 0.032 × 10 = 12320

I = $ 12,320.00

The simple interest accumulated

on a principal of $ 38,500.00

at a rate of 3.2% per year

for 10 years is $ 12,320.00.
