A group of friends are at a baseball game and are purchasing souvenirs. Olivia purchased 1 t-shirt and 5 baseball caps, spending a total of $165. Her Marco purchased 1 t-shirt and 4 baseball caps, which cost him a total of $137. Assuming that all of the t-shirts and all of the caps are the same price, what is the price of each?
Answer:
baseball cap = $28
t-shirt = $25
Step-by-step explanation:
Olivia: t +5b = 165
Marco: t + 4b = 137
isolate t in Olivia's equation
t = 165 - 5b
plug t into Marco's equation
165 - 5b + 4b = 137
165 - b = 137
b = 28
plug b into either equation
t + 4b = 137
t + 4(28) = 137
t + 112 = 137
t = 25

sixty-eight percent of valley creek school students attend this year's homecoming dance if 459 students attend the dance how many students are in the school?
The total number of students in the school will be 675.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that sixty-eight per cent of valley creek school students attend this year's homecoming dance if 459 students attend the dance.
The number of students will be calculated as,
68% ⇒ 459
1% ⇒ 459 / 68
100% ⇒ (459 x 100 ) / 68
100% ⇒ 675 students
Therefore, the total number of students in the school will be 675.

An equation of a line that goes through -1/-3 and is parallel to the line 6x - y =1
Answer:
y=6x+3
Step-by-step explanation:
1.6x-y=1 solve for y
-y=-6x+1 divide bot sides by -1
y=6x-1
slope is 6
the slopes of parallel lines are equal
y-(-3)=6(x-(-1))
y+3=6(x+1)
y+3=6x+6
y=6x+6-3

16. The temperature of an oven at 0°C has an
absolute temperature of TK where
T= t+273°.
a) Find the absolute temperature of the
oven at a temperature of 27C.
Answer:
300K
Step-by-step explanation:
T = t + 273 °C
T is absolute temperature
t = given temperature (27°C in this case)
Hence T = 27 °C + 273 °C (standard temperature)
T = 300K (since absolute temperature is measured in K from the question's preamble)

Answer:
- 4Step-by-step explanation:
Slopes of perpendicular lines are negative-reciprocals.If m is the slope of one line, the slope of the perpendicular line is -1/m.Let's find the slope of the given line:
x - 4y = -12Rewrite this in the slope-intercept form: y = mx + b
x - 4y = -124y = x + 12y = 1/4x + 3The slope is 1/4

- 1/(1/4) = - 4how many ounces are equivalent to 6 pounds?
Answer:
96
Step-by-step explanation:
1 pound is 16 ounces
6 pounds=x ounces
So we use the X to signal it's presence
1x16 is 16,
That means 16 ounces
6xP=Q
6x16 will give us our answer
Because it will tell us how many pounds there are since ounces is multiplied to get ounces.
6x16=96
P=16
Q=96
96 is our answer.

14. A system of equations is shown below. For what value of a will this system have no solutions? Justify your answer.
y = 4x-9
y = ax+6
Answer:
a = 4
Step-by-step explanation:
a = 4
If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.
Answer:
x can not equal zero, as it would cause division by zero.
Step-by-step explanation:
First, let's make one equation out of them and see what we get. Because both of them have y on the left, we can say that the two right sides are equal, giving us:
4x - 9 = ax + 6
If we solve for a, we get:
ax + 6 = 4x - 9
ax = 4x - 15
a = 4 - 15 / x
With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.

Hikers on a backpacking trip take 2 hours and 10 minutes to hike the first 2.6 miles of an 8-mile hike. At this pace, which amount of time best approximates how long they will take to hike the entire 8 miles of the trip.
A. 6 hours and 30 mins
B. 6 hours and 40 mins
C. 7 hours and 35 mins
D. 9 hours and 36 mins
Answer:
B. 6 hours and 40 mins
Step-by-step explanation:
Create a proportion where x is the amount of time to hike the entire 8 miles.
Represent the time in minutes:
[tex]\frac{130}{2.6}[/tex] = [tex]\frac{x}{8}[/tex]
Cross multiply and solve for x:
2.6x = 1040
x = 400
Convert this to hours:
400/60
= 6.67 (6 hours and 40 mins)
So, the correct answer is B. 6 hours and 40 mins
