Ian owns a small business selling used books. He knows that in the last week 19
customers paid cash, 30 customers used a debit card, and 77 customers used a credit
card.
If next week, he is expecting 1800 customers, about how many would you expect to
pay with a credit card? Round your answer to the nearest whole number.
Answers
Step-by-step explanation:
last week there were 19+30+77 = 126 customers.
19/126 = 1/14 paid cash.
30/126 = 5/21 paid by debit card.
77/126 = 11/18 paid by credit card.
next week he expects 1800 customers.
that is compared to 126 a factor of
1800/126 = 300/21 = 100/7
now we actually only need to apply the same factor to any part of the total sum to get their share in the new total sum.
it simply follows the rule
(a + b + c) × d = ad + bd + cd
so,
77 × 100/7 = 11 × 100 = 1100 customers are expected to pay per credit card.

Which inequality matches the graph shown below? y < -2x-1, y > -2x-1, y > 2x-1, y < 2x-1
Answers
Answer:
y > 2x - 1
Step-by-step explanation:
the first thing we see in the graph is the dotted line. so, the line itself will not be included. therefore, no "<=" or ">=", but there was none in the answer options anyway.
then we see the shaded area is "above" (in tendency) the line. so, we are talking about a "y > ..." inequality.
then we see the y-intercept (the y value when x=0). it is -1, but all the answer options have "-1" as y-intercept. OK.
and then we see the slope of the line. when checking after (0, -1) the next point on the line with whole numbers as coordinates, we find (1, 1). so, while x increased by 1, y increases by 2. so, the slow is "y change"/"x change" = 2/1 = 2
so, in total, we are looking for the line
y = 2x - 1
and to cover the whole area above the line (but without the line) we get then
y > 2x - 1

Tyra's family is spending the afternoon in Millersville. They plan to see a movie and
then explore the town. The movie will cost the family $36, and parking costs $4 per
hour.
How long will the family be able to spend in Millersville if they want to spend less
than $60 and they don't have any other expenses?
Answers
Answer:
Step-by-step explanation:
Let the family spent 'x' hours in the town.
Parking cost for 'x'hours = 4*x = 4x
Now the total amount = Cost of the movie ticket + parking cost
= 36 + 4x
Total cost should be less than $ 60
36 + 4x < 60
Subtract 36 from both sides
4x < 60 - 36
4x < 24
Divide both sides by 4
x < 24/4
x < 6
The family can spend less than 6 hours in the town.

sine = “opposite”/hypotenuse
Unfortunately, I currently can’t draw a diagram, but if you draw a right triangle with corners labeled I, H, and G, the side opposite to angle G is 33. The hypotenuse, aka the longest side of the triangle, is 65.
Hence, the ratio would be 33/65.
