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?
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.
Felix has a bag of 6 yellow marbles and 6 green marbles. He picks a marble and then puts it back 26 times. The results are shown in the table. Outcome Tally Yellow 15 Green 11 What is the percent error of pulling a yellow marble in Felix’s experiment? A. 13.3% B. 15.4% C. 23.1% D. 42.3%
whats the answer to this? (with an explanation please)
Answer:

no. of green marbles = 6
total no. of marbles = 12
he picks and put the marbles for 26 times
he pick yellow for 15 times
he pick green marble for 11 times

What is a triangle?A triangle is a polygon with three sides and three angles. The angles in a triangle sum up to 180°.
Types of triangles are scalene, isosceles, equilateral and right angled triangle.
Let x represent the third angle of a triangle with angle measures of 30° and 120°. Hence:
x + 120 + 30 = 180° (sum of angles in a triangle)
x = 30°
Since two angles are the same, hence two sides have the same length.

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.
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.

Ajar contains 35 dimes and nickels. The total value of the coins is $2.50. If
d = the number of dimes and n = the number of nickels, this is the system of
equations:
d+ n = 35
0.100+ 0.05n = 2.50
How many of each type of coin are there? Solve the system to answer the
question
Answer:
0.05x+0.10(35-x)=2.50
(0.05x+3.5-0.10x=2.50) get rid of devimal points by multiplying both sides by 100
5x+350-10x=2505x-10x +350-350=250-350(-5x= 100)divide both by -5-5x/-5= -100/-5x=20(the number of nickels)The number of dime is35-x. and x=2035-20=15the number of dimes is = 15the number of nickels is = 2020nickels =$1.0015dimes =$1.50check

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

The distance is 10.5 miles
The speed of driving is 45 miles/ hour
Time period = ?
Let t denotes the time taken to reach
Speed = Distance / Time
45 = 10.5 / t
t = 10.5/45 = 0.233 hours
t = 0.233 *60 = 14 minutes
Therefore, the time taken to reach the scene is 14 minutes, the correct option is D.
