Juan's family and Ethan's family go to a food stand.
• Juan's family buys three hot dogs and four drinks for $18.50.
• Ethan's family buys five hot dogs and four drinks for $25.50.
What is the cost of one drink at the food stand?
Answer:
1 hotdog is $3.5.
1 drink is $2.
Step-by-step explanation:
18.50= 3x+4y(times 5)
25.50=5x+4y(times -3)
92.5=15x+20x
-76.5=-15x+-12y
16=-8y
2=y
18.50=3x+4(2)
10.50=3x+8
10.50=3x
3.5=x

Samir is working on a project and has cut a number of wooden blocks of equal size that are represented by this right rectangular prism. He now needs to cover the wooden blocks on all sides with a blue fabric.
How much fabric does Samir need in order to cover 5 of these blocks?
12 cm²
34 cm²
60 cm²
170 cm²
Answer:
170 cm
Step-by-step explanation:
2 * 1 1/2 * 2 = 6
1 1/2 * 4 * 2 = 12
2 * 4 * 2 = 16
In total: 6 + 12 + 16 = 34.
Samir needs to cover 5 of these blocks so: 34 x 5 = 170
I also did the quiz.
Answer: 170cm

Colin put a pie in the oven at 1:35 p. M. He took the pie out at 2:17 p. M. How long was the pie in the oven?
Answer:
42 minutes
Step-by-step explanation:
there are 60 minutes in one hour.
from 12 pm, 1 hour and 35 minutes have passed to get to 1:35 pm
from 12 pm, 2 hours and 17 minutes have passed to get to 2:17 pm
we are trying to figure out the start to end time, or the difference between the times
2 hours and 17 minutes - 1 hour and 35 minutes
1 hour = 60 minutes
if we convert everything to minutes we can get a definitive time in one single unit
2 hours = 1 hour * 2 = 60 minutes * 2 = 120 minutes
1 hour = 60 minutes
plug these in
(120 + 17) minutes - (60 + 35) minutes
= 137 minutes - 95 minutes
= 42 minutes as our answer

Answer:
60°
Step-by-step explanation:
the triangle need to have 180°. The up right corner is 60 because 120 + 60 = 180. Then I extended to rhombus where you have two sets of same angles. 125 + 55 = 180. 125 + 125 = 250. 360 - 250 = 110. 110 ÷ 2 = 60

Find the lateral area of the prism
Answer: 50, 208 mm²
Step-by-step explanation:
The lateral area is the surface area excluding the bottom, also known as the base. This means we will be solving for two rectangles and two triangles.
[The Rectangles]
They are both congruent, so I will do the following;
A = 2(L * W)
A = 2(7 mm * 24 mm)
A = 2(168 mm)
A = 336 mm²
[The Triangles]
The area of a triangle is [tex]\frac{B * H}{2}[/tex] However, they are both congruent. I will do the following;
A = B * H
A = 24 mm * 2,078 mm
A = 49,872 mm²
[The Total]
Lastly, I will add them together.
336 mm² + 49,872 mm² = 50, 208 mm²

There are two mechanics who work on cars. For each mechanic, the relationship between x, the number of hours worked, and y, the total cost, in dollars, is described below. • The equation y = 36x represents the total cost charged by Mechanic A for the number of hours worked. The graph shown below represents the total cost charged by Mechanic B for the number of hours worked.
Answer:
B
Step-by-step explanation:
if you divide the 2/88 you should get a price of 44. So Mechanic B charges $44 while Mechanic A charges $36. Subtract 44-36 and get 8. Since Mechanic B charges more, it would give you the answer listed in B.
The equation satisfies option B, Mechanic B charges $8 more per hour then mechanic A.
What is graph?a collection of all points whose coordinates satisfy a given relation (such as a function) a diagram that represents the variation of a variable in comparison to that of one or more other variables, such as a series of one or more points, lines, line segments, curves, or areas
The fundamental subject of graph theory is graphs.
Given the Equation for cost charged by Mechanic A
y = 36x
where y = total cost and x = hours worked
graph shows the total cost charged by Mechanic B
from graph we the coordinates (0, 0) and (2, 88)
when x = 0, y = 0 and when x = 2, y = 88
the equation satisfy the condition is
y = 44x
cost for one hour for Mechanic A
y = 36x (x = 1)
y = $36
cost for one hour for Mechanic B
y = 44x (x = 1)
y = $44
Mechanic B is $8 more than Mechanic A
Hence Mechanic B charges $8 more per hour then mechanic A.

What is the sum of the geometric sequence 1, 3, 9, ... if there are 11 terms? (5 points) 29,524 55,987 87,381 88,573
Answer:
S₁₁ = 88573
Step-by-step explanation:
the sum to n terms of a geometric sequence is
[tex]S_{n}[/tex] = [tex]\frac{a_{1}(r^{n}-1) }{r-1}[/tex]
where a₁ is the first term and r the common ratio
here a₁ = 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{3}{1}[/tex] = 3 , then
S₁₁ = [tex]\frac{1(3^{11}-1) }{3-1}[/tex] = [tex]\frac{1}{2}[/tex] (177147 - 1) = [tex]\frac{1}{2}[/tex] × 177146 = 88573

To factor p^2 - 5p -14 we need to find ___ of ____ that will also add to equal ____.
Answer:
We need to find Factors of 14 that will also add and equal to 5
Step-by-step explanation:
Trinomial factorising
Answer:
see explanation
Step-by-step explanation:
p² - 5p - 14
We need to find the factors of the constant term (- 14) that will also add to give the coefficient of the p- term (- 5)
the factors are - 7 and + 2 , since
- 7 × + 2 = - 14 and - 7 + 2 = - 5
then
p² - 5p - 14 = (p - 7)(p + 2) ← in factored form

Answer:
The X-coordinates will decrease by 6 units because, anytime you move something to the left on a coordinate plane you are decreasing the x value
Answer:
The x-coordinates will decrease by 6.
Step-by-step explanation:
So when you look at a graph, the left side has smaller numbers than the right side because as you go down it becomes negative and the right means it is going positive. So if you are moving to the left you are getting smaller so you are decreasing. The other options with y-axis is not true because the y-axis is vertical.
