K= 8. If you look at the pattern each x value is multiplied by 8 to give you the y value. You could also solve it by:

40=k5
40/5=k
8=k

you could do this with any of the x or y values and still end up with 8.

Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h

23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified


24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values

.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.

At Ralphs Italian Ices, 145 sundaes were sold in June. Sales were up 23% in July, How many sundaes were sold in July?​
elena-s [515]
178 sundaes were sold in July.

To calculate a percentage, we convert to a decimal by dividing by 100. So 23% = 0.23

145 x 0.23 = 33.35 This is how many more sundaes were sold in July than June. We need to add the 145 sold in June to the increased number to find July’s total.
145 + 33.35 = 178.35

You can’t sell .035/ roughly a third of a sundae, so we round to the whole number.
