Answer:

4.99

Step-by-step explanation:

i cant remember how i got 4.99 but can show u how to check

= 55 +<u> 4.99 </u>= 59.99

59.99 divide <u>3</u> = 19.99666667

= 19.99666667 divide 4 (working in reverse as it says 4 times the orig no.)

= 4.99 (was rounded)

Complete the square to put () in vertex form. () = 3<br> 2 + 30 − 12. What is the vertex?
gulaghasi [49]

Answer:

A and A

the equation of a parabola in vertex form is

y = a(x - h)² + k

where ( h, k ) are the coordinates of the vertex and a is a multiplier

y = - 2(x + 3)² + 2  is in this form

with vertex = ( - 3, 2)

To find the y-intercept let x = 0

y = - 2(3)² + 2 = - 18 + 2 = - 16

Similarly

y = - 2(x + 2)² + 2 is in vertex form

vertex = ( - 2 , 2)

x = 0 : y = - 2(2)² + 2 = - 8 + 2 = - 6 ← y- intercept

hope this helped

Out of £20 pocket money Rachel spends £13.50 expressed as a percentage​
prohojiy [21]

13.50 : 20 = x : 100

x = \frac{13.5 * 100}{20}

x = \frac{1350}{20}

x = 67,5

percentage = 67,5%

Calories burned varies directly to miles run. Dustin burns 190 calories for every 2 miles he runs. Part 1: Find the value of k.
Temka [501]

Answer:

C = km

k = 95

C = 665

Step-by-step explanation:

Calories burned varies directly to miles run.

Let

C = calories burned

m = miles

C = km

Dustin burns 190 calories for every 2 miles he runs

C = 190

m = 2

C = km

190 = k2

Divide both sides by 2

k = 95

equation for the direct variation.

C = km

Find how many calories Dustin will burn after running 7 miles.

C = ?

m = 7

k = 95

C = km

C = 95 × 7

= 665
