How did you compute the cost of 4 pounds of beef at $5.89 per pound? Use this example to explain your strategy.
Answer:
$23.56
Step-by-step explanation:
Step one:
given data
We are told that the unit cost per pound is $5.89
Required
the cost of 4 pounds
If 1 pound cost $5.89
4 pounds cost x
cross multiply
x= 4*5.89
x=$23.56

Answer:
x = 14.375
Step-by-step explanation:
Ok, so we know that a triangle has a total interior degree of 180°. And since we already have a 95° angle, we just need to subtract 95 from 180.
180° - 95° = 85°
Now, we already have indicators that two of the three sides are equal. And we already got the angle of the side that does not have a matching partner. So we just need to divide what we already have by 2.
85° / 2 = 42.5°
Now that we know each side is 42.5 degrees, we just need to grab our given equation and put and equal sign at the end with what we already know is the answer (since we are trying to solve for x).
(4x - 15) = 42.5
Now, let's just get rid of those useless parentheses.
4x - 15 = 42.5
Next, we just need to have the variable on its own side, all by itself. So, in order to do that, we just add 15 to both sides.
4x = 57.5
Now, for our final step, we just need to divide each side by our variables' factor (which is a positive 4). In which we get our final answer of:
x = 14.375
Answer:
x = 14.375
Step-by-step explanation:
Since 2 sides are congruent then the triangle is isosceles and the base angles are congruent, both (4x - 15)
The sum of the 3 angles in the triangle = 180°
sum the angles and equate to 180
4x - 15 + 4x - 15 + 95 = 180 , that is
8x + 65 = 180 ( subtract 65 from both sides )
8x = 115 ( divide both sides by 8 )
x = 14.375

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
Simplify the rational expression:
5y+5/2 ÷ 25y-20/40y²-32y
Step-by-step explanation:
Your problem → 5y+5/2 / 25y-20/40y^2-32y
5y+5/2÷25y-20/40y^2-32y
=5⋅y+5/2÷25×y-20/40×y^2-32×y
=5y+5/2÷25×y-20/40×y^2-32y
=5y+5/2×1/25×y-20/40×y^2-32y
=5y+y/10-20/40×y^2-32y
=5y+y/10-y^2/2-32y
=5y×10+y-y^2×5-32y×10 ÷ 10
=50y+y-5y2-320y ÷ 10
= -269y-5y^2 / 10
Two brothers, Jim and John, had a straight log in their backyard. Jim wanted the log cut into 24 equal parts. He painted red lines on the log and called to a lumberjack to cut the log by the painted lines. John wanted the log cut too, but into 18 equal parts. He painted yellow lines on the log with some yellow lines painted over red lines. The lumberjack came and cut the log by the painted lines. How many cuts did the lumberjack make?
Answer:
432
Explanation:
If the lumberjack follows Jim's instruction and cuts the log of wood into 24 parts the first time, the log of wood has 24 parts
If the lumberjack follows John's instruction to further cut the log of wood already cut into 24 parts then we would have 24×18= 432 parts of the log of wood

The correct substitution for the formula is a = 3,b= -2 and c=0.
What is a quadratic equation?
It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
The given quadratic equation is,
1 = –2x + 3x² + 1
3x²-2x + 0 = 0
The formula is,
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
The standard form of the quadratic equation is,
ax² + bx + c = 0
Compare the equation with the standard equation.
a = 3
b = -2
c = 0
Therefore, the correct substitution for the formula is a = 3,b= -2 and c=0.

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.

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

The slope of a line is the ratio of rise to run for any two points on a line. Is this a true statement? Explain in two to four sentences. If false, provide a corrected statement.
Answer:
True
Step-by-step explanation:
The slope is the ratio of rise to run for any two points on a line.
The rise is the change in vertical axis, y
Rise = y2 - y1
The run is the change in the horizontal axis, x
Run = x2 - x1
Slope is the ratio of both:
Rise / Run = (y2 - y1) / (x2 - x1)

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.

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.
