Liam is a tyre fitter question

Answers

Answer:

a) 168

b) 3

Step-by-step explanation:

a) 56÷4=14 14×12=168

b) 56÷4=14 56-14=42 42÷14=3

If we say it takes 56 min to fit 4 tyres to one van

Let's caunt how many min for only one tyre and one van

It will take 56 min /4 = 14 min
So it will take only 14 min for 1 tyre in one van.

Let's solve a

A) 12 tyres to 3 van.
If we will say it will take 14 min for each tyre in one van
So 12 tyres will take 14 min * 12 = 168 min which is equal 2 hours and 48 min .

B) as we said it will take only 14 min for 1 tyre.
So 42/14 =3
So he will install 3 tyres in 42 min

what is the equation of the line that passes through the point(-5,-4) and has a slope of -3/5?

Answers

Answer:

y= mx+c

-4= -3/5(-5) + c

-4= -3/5 *-5+ c

-4=3+c

-4-3=c

-7=c

therefore the equation of the line is y=-3/5x-7

Step-by-step explanation:

the equation of a line is

y=mx +c

where y is the y coordinate

where m is the slope

where x is the x coordinate

where c is the y- intercept

v∆ABC is translated 6 units up and 3 units left to create ∆A'B'C'.
if vertex A is at (-1, 2) and vertex B is at (1, 5), then vertex A' is at and vertex B is at

Answers

Answer:

see explanation

Step-by-step explanation:

A translation of 6 units up means adding 6 to the y- coordinate

A translation of 3 units left means subtracting 3 from the x- coordinate

The translation rule is (x, y ) → (x - 3, y + 6 ) , then

A (- 1, 2 ) → A' (- 1 - 3, 2 + 6 ) → A' (- 4, 8 )

B (1, 5 ) → B' (1 - 3, 5 + 6 ) → B' (- 2, 11 )

The x-intercept of f(x) is 5. If g(x)=f(x+2), then what is the x-intercept of g(x)?

Answers

Answer:

To find the

x- intercept, we set y=0 and solve for x:0=.5x−3

3=.5x

6=x

So. the x-intercept is

(6,0)

To find the

y-intercept, it's a similar system We set x=0 and solve for y this time.

y=.5⋅0−3

y=−3

That was easy :)

So, our y-intercept is (0,−3)

Just to double check our work, let's graph the equation and see the

x and y- intercepts

graph{y=.5x-3}

Yep,

(6,0) and (0,−3). We were right!

the area of a square is 400 units. if the length of each side of the square increased by one unit, would its area be a rational number

Answers

Answer:

Yes, the area of the square would be a rational number.

Step-by-step explanation:

Area of square = 400 units² = x²

x = one side length of square

x = √400 = 20 units

Increase each side length by 1 unit.

New side length = 21 units

Area of new square = 21² = 441

441 is a rational number because the square root of 400 is a rational number.

√400 = 21

Therefore: If the length of each side of the square increased by one unit, the area of the square would be a rational number. The area of the square would still be a perfect square.

What is the regular monthly rate for each phone?​

Answers

Answer:

22.45

Step-by-step explanation:

ixl told me a

Answer:

$22.45 per month

Step-by-step explanation:

Fred's family will pay for cell service for 5 phones at a regular monthly rate of c dollars for each phone. They will also receive a discount of $50. The first month's payment will be $62.25. This equation represents the situation.

5c

50

=

62.25

monthly cost of cell service for 5 phones

one-time discount

first month's payment

Now, solve the equation for c.

5c–50

= 62.25

5c

= 112.25 Add 50 to both sides

c

= 22.45 Divide both sides by 5

The regular monthly rate for each phone is $22.45.
