Step-by-step explanation:
A factory uses 1/6 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 1/2 of a barrel of raisins. How many batches of granola bars did the factory make yesterday? Simplify your answer and write it as a proper fraction or as a whole or mixed number.
Answer:
The factory made 3 batches of granola bars.
Step-by-step explanation:
Given that:
1/6 barrel of raisins is used in each batch of granola bars.
1/6 barrel = 1 batch
1/2 barrel = x batches
As the relationship is proportional,
1/6 : 1 :: 1/2 : x
Product of mean = Product of extreme
[tex]\frac{1}{6}x=\frac{1}{2}[/tex]
Multiplying both sides by 6
[tex]6*\frac{1}{6}x=\frac{1}{2}*6\\x=3[/tex]
Hence,
The factory made 3 batches of granola bars.

A construction job for gallery 10 painters were tasked with painting the interior these painters made up 40% of the painting crew so how many painters in all worked on this job
Answer:
Total number of painters = 25 painters
Step-by-step explanation:
Interior painting = 10 painters
These painters made up 40% of the painting crew
how many painters in all worked on this job?
Let
Total number of painters = x
Interior painters = 40% of x
10 = 40% * x
10 = 0.4 * x
10 = 0.4x
x = 10/0.4
x = 25 painters
Total number of painters = x = 25 painters

The drama club sells hot drinks during intermission for the school play. At one performance they sold $200 worth of drinks. Karen knows that they sold 295 total drinks. If hot chocolate sold for $0.75 and coffee sold for $0.50, then how many of each hot drink did the drama club sell?
Answer:
they sold 210 hot chocolates and 85 coffees
Step-by-step explanation:
We know that they sold $200 worth of drinks
x will be the number of hot chocolates sold
y will be the number of coffees sold
This means that
.75x+.5y=200
We also know that they sold 295 total drinks which means that
x+y=295
This is a system of linear equations which I will solve through substitution
x+y=295
Subtract y from both sides and divide by -1 to get
-x+295=y
Plug y into the first equation and get
.75x+.5(-x+295)=200
Distribute the .5 and simplify to get
.75x-.5x+147.5
.25x+147.5=200
Subtract 147.5 and then divide by .25 to get our x value
x=210
Now we can go back and plug this in into our equation
210+y=295
Subtract 210 to get y
y=85
This means that they sold 210 hot chocolates and 85 coffees

Answer:
Step-by-step explanation:
We need to find whether the two given triangles are congruent.
The given triangles are congruent.
The distance between two points is given by
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
A(2,-8) and B(-5,-2)
[tex]AB=\sqrt{(-5-2)^2+(-2-(-8))^2}\\\Rightarrow AB=\sqrt{49+36}\\\Rightarrow AB=\sqrt{85}[/tex]
D(-9,7) and E(-11,12)
[tex]DE=\sqrt{(-11-(-9))^2+(12-7)^2}\\\Rightarrow DE=\sqrt{29}[/tex]
B(-5,-2) and C(-7,3)
[tex]BC=\sqrt{(-7-(-5))^2+(3-(-2))^2}\\\Rightarrow BC=\sqrt{29}[/tex]
E(-11,12) and F(-2,1)
[tex]EF=\sqrt{(-2-(-11))^2+(1-12)^2}\\\Rightarrow EF=\sqrt{202}[/tex]
A(2,-8) and C(-7,3)
[tex]AC=\sqrt{(-7-2)^2+(3-(-8))^2}\\\Rightarrow AC=\sqrt{202}[/tex]
D(-9,7) and F(-2,1)
[tex]DF=\sqrt{(-2-(-9))^2+(1-7)^2}\\\Rightarrow DF=\sqrt{85}[/tex]
It can be seen that [tex]AB=DF=\sqrt{85}[/tex], [tex]BC=DE=\sqrt{29}[/tex] and [tex]AC=EF=\sqrt{202}[/tex].
Since, each side of triangle ABC is equal to one side of triangle DEF they are congruent to each other.

What is the calculation for determining simple interest and compound interest? Borrowing if borrowed $20,000 for 5 years at a 4% interest rate? What is total interest paid?
Answer:
If using simple interest, the formula is:
= Amount * ( 1 + rate * time)
= 20,000 * ( 1 + 4% * 5)
= $24,000
Interest = Balance after 5 years - Investment
= 24,000 - 20,000
= $4,000
Using Compound Interest:
= Amount * ( 1 + rate)^time
= 20,000 * ( 1 + 4%)⁵
= $24,333.06
Interest = 24,333.06 - 20,000
= $4,333.06

Emmanuel walks at an average speed of 5 m/min. How far does he walk in 1.7 hours? What formula do you use to solve the problem?
Answer:
Emmanuel will walk 510 miles in 1.7 hours.
Step-by-step explanation:
Given that Emmanuel walks at an average speed of 5 m/min.
It means:
Average speed = 5 miles per minAs there are 60 minutes in 1 hour.
so
1.7 hours = 102 minutes
Thus,
The walking distance in 102 minutes = 5 × 102
= 510 miles ∵ 1 min = 5 miles
Therefore, Emmanuel will walk 510 miles in 1.7 hours.

A line passes through (4, 5) and (8, 9). Which equation best represents the line?
y = x + 1
y = 1
y = 2x + 1
y = 5x + 8
Answer:
y = x + 1
Step-by-step explanation:
1) First, find the slope of the line between the two points. Whichever option has the same slope would be the right answer. To find this, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point.
So, use the points given to answer the question. Substitute 4 for [tex]x_1[/tex], 5 for [tex]y_1[/tex], 8 for [tex]x_2[/tex], and 9 for [tex]y_2[/tex] then solve:
[tex]\frac{(9)-(5)}{(8)-(4)} \\= \frac{9-5}{8-4} \\= \frac{4}{4} \\= 1[/tex]
Therefore, the slope is 1.
2) Any line that is in a "y = a number" format is a horizontal line, and all horizontal lines have a slope of 0 - so the second option can't be the answer.
The rest of the options are in slope-intercept form, or y = mx + b format. Remember that the coefficient of the term with the x is the slope. Knowing this, y = x + 1 would need to be the answer since the coefficient of the term with the x is 1, and we already calculated that the slope is 1.

On average sasha can drive 28 miles on every gallon of gasoline if she fills up her tank for $2.25 per gallon how much will it cost her to drive 336 miles
Answer:
It will cost her $27 to drive 336 miles.
Step-by-step explanation:
With the information provided, you can use a rule of three to find how much it will cost to drive 336 miles given that driving 28 miles costs $2.25:
28 miles → $2.25
336 miles → x
x=(336*2.25)/28= 27
According to this, the answer is that it will cost her $27 to drive 336 miles.
