Answer:

1st question = 27 degrees

Step-by-step explanation:

Angles in a circle add up to 360 degrees

2x +21 +5x + 6+ 90+ 54 = 360

7x + 171 = 360

7x = 189

x = 27 degrees

Samantha drew Triangle JKL with the coordinates (2,3), (4, 3) and (5,2). She reflected this image over the x-axis to create an i

zavuch27 [327]

Answer:

J'(2,-3), K'(4, -3) and L'(5,-2)

Step-by-step explanation:

The given triangle has vertices at J(2,3), K(4, 3) and L(5,2).

The transformation rule for a reflection in the x-axis is:

$(x,y)\to (x,-y)$

We substitute the points to obtain the coordinates of the image triangle J'K'L'

$J(2,3)\to J'(2,-3)$

$K(4,3)\to K'(4,-3)$

$L(5,2)\to L'(5,-2)$

In other words, we negate the y-coordinates of triangle JKL to obtain the coordinates of J'K'L'

if your car gets 28 miles per gallon, how much does it cost to drive 310 miles when gasoline cost $3.50 per gallon?

Butoxors [25]

Hi,

Work:

$28miles = 1gallon$

To find the cost of gallons spend for 310 miles you need to first find the amount of gallons consumed on 310 miles path.

$310 \div 28 = 11.07gallons$

If each costs 3.5$ you need to multiply gallons with money.

$3.5 \times 11.07 = 38.745$

You would spend 38.745$ to drive 310 miles.

Hope this helps.
