A=-5
a12 = 1.7

a12 = a+(n-1)d
1.7 = -5+(12-1)d

1.7+5 = 11d

6.7/11 = d
0.60 = d

The Sunrise Cafe gets tea bags in boxes of l,000. If the cafe charges $1.75 for each cup of tea, and each cup of tea gets one te
WARRIOR [948]
Well you would do $1.75 x 1,000. That would be 1,750$.

Then you would take away that 95$ they spent buying the box of tea bags and their total would be 1,750$ - 95$ = 1,655$.

Jim spent $46.16 on some mulch and one shovel. Each bag of mulch costs $3.49 and the shovel cost $14.75. How many bags of mulch
mezya [45]
To find the amount he spent on bags of mulch you must take the cost of the shovel away from the total, giving the equation:
46.16-14.75=3.49x
To covert this to whole numbers, multiply by 100
4616-1475=349x
3141=349x
x=9

Which is the most accurate description of the polygon?
kherson [118]
Let’s take a look at the definitions of all of these categories of polygon:

A rhombus is a quadrilateral with four equal-length sides

A trapezoid is a quadrilateral with at least one pair of parallel sides

A kite is a quadrilateral with two pairs of equal sides, where those sides are adjacent to each other

A quadrilateral is a four-sided polygon

And let’s compare our definitions with the figure:

- None of the sides of the figure are equal to each other, so we it can’t be a rhombus
- The slopes of all of the sides are different, so the figure can’t have a pair of parallel lines, ruling out the chance that it’s a trapezoid
- That first bullet point also rules out the possibility that our figure is a kite
- Our figure *is* a four-sided polygon though, so it meets the requirements for a quadrilateral

So, the only label that works for this figure is a *quadrilateral*.

astraxan [27]

Answer:

28126 total

Step-by-step explanation:

1240-780=460

24.50 - 20%=4.90

24.50-4.90

780*24.50=19110

19.60 * 460=9016

19110+9016=28126
