Baseball hat is on sale for 15% off, which is $2.70. How much does the baseball hat cost at full price?
lidiya [134]

Answer:

27.9 dollars

Step-by-step explanation:

2.70= 15 percent

2.70x2=5.4=30 percent

5.4+2.70=8.1=45 percent

8.1x2=16.2=95 percent

95 percent + 15 percent=18.9

18.9=105 percent

in order to subtract 5 percent we need to find 5 percent by dividing 2.70 by 3

which = .9

18.9+9=27.9

100 percent is 27.9 dollars

Complete the square to rewrite y = x2 - 6x + 3 in vertex form. Then state
Vladimir [108]

Answer:

see explanation

Step-by-step explanation:

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

Given

y = x² - 6x + 3

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² - 6x

y = x² + 2(- 3)x + 9 - 9 + 3

  = (x - 3)² - 6 ← in vertex form

• If a > 0 then vertex is a minimum

• If a < 0 then vertex is a maximum

Here a = 1 > 0, thus

(3, - 6 ) is a minimum

Work out the equation of the line which has a gradient of 2 and passes through the point (1, 4)
leva [86]

Answer:

y = 2x + 2

Step-by-step explanation:

The slope is also called the gradient of the line.

The slope that is given is two, and the point is (1, 4).

I made a point slope equation, and then converted it into a slope-intercept equation.

y-4=2(x-1)\\\\y-4=2x-2\\\\y-4+4=2x-2+4\\\\\boxed{y=2x+2}

Hope this helps.

A middle school is selling tickets to a play. The number of child tickets sold is half the number of adult tickets sold. They so
Sidana [21]

Answer:

child tickets - 47

adult tickets - 94

Explanation:

since the number of adult tickets sold is twice that of the number of child tickets sold, we can divide 141 into three parts to find the number of child tickets sold.

141 ÷ 3 = <u>47</u> (number of child tickets sold)

we can now multiply this by two to find the number of adult tickets sold.

47 × 2 = <u>94</u>

i hope this helps! :D
