An expression is shown.
1 3/7 divided by 1 1/3
What is the value of the expression as a mixed number?
Answer:
1 ¹⁄₁₄
Step-by-step explanation:
[Step 1] [convert mixed fractions to improper fractions]
1 3/7 divided by 1 1/3 →
a b/c = b + a(c) / c = (b + ac) / c.
3 + 1(7) / 7 divided by 1 + 1(3) / 3 →
10 / 7 divided by 4 / 3.
[Step 2] [flip the numerator and denominator(take the reciprocal) of the fraction you are dividing by and multiply]
10 / 7 divided by 4 / 3 →
a / b → b / a = 1 / (a / b) = (a / b) ^ -1.
10 / 7 multiplied by (3 / 4).
When you multiply 2 fractions, you multiply across. Numerator × Numerator / Denominator × Denominator.
a / b × c / d = (a × c) / (b × d).
10 / 7 multiplied by (3 / 4) →
10 / 7 × 3 / 4 →
(10 × 3) / (7 × 4) →
30 / 28.
[Reduce completely until the denominator or numerator is prime or can only be divided by one and itself to remain an integer]
30 / 28 →
15 / 14.
[Find the difference between the numerator and denominator and that will be the numerator of the mixed fraction or the remainder, the denominator will be the same denominator of the improper fraction and the whole part will be how many times the denominator can fit in the numerator of the improper fraction]
[Or you can do long division and you will add the quotient (top number above long division bar) and the remainder.]
a / b = (# times b fits into a) + (remainder / b).
15 / 14 = (# times 14 fits into 15) + (1 / 14).
15 / 14 = 1 + (1 / 14)
15 / 14 = 1 ¹⁄₁₄

Step-by-step explanation:
If the diameter of the circle below is 16 in., what is the area of the circle?
Answer:
64π inches² (approximately 201.06 inches²)
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius
To find the radius, divide the diameter by 2
16 ÷ 2 = 8 inches
Plug in 8 as the radius
[tex]A=\pi (8)^2\\A=64\pi[/tex]
[tex]A=201.06[/tex] (approximately)
Therefore, the area of the circle is 64π inches², or approximately 201.06 inches².
I hope this helps!
Answer:
201 inch²
Step-by-step explanation:
d=2r ⇔ 16=2r ⇔ r=8
A= Pi× r² ≈ 3.14 × 8² ≈ 201 inch²

Solve for h.
h/6 − 1 = −3
h =
Answer:
[tex]h = - 12[/tex]
Step-by-step explanation:
1) Add 1 to both sides.
[tex] \frac{h}{6} = - 3 + 1[/tex]
2) Simplify -3 + 1 to -2.
[tex] \frac{h}{6} = - 2[/tex]
3) Multiply both sides by 6.
[tex]h = - 2 \times 6[/tex]
4) Simplify 2 × 6 to 12.
[tex]h = - 12[/tex]
Therefor, the answer is h = -12.
Answer:
h = - 12
Step-by-step explanation:
Add 1 to both sides of the equation
ℎ/6 − 1 + 1 = − 3 + 1
Simplify
ℎ/6 = − 3 + 1
h/6 = -2
Multiply all terms by the same value to eliminate fraction denominators
6 ⋅ ℎ/6 = 6 ( − 2 )
Cancel multiplied terms that are in the denominator
ℎ = 6 ( − 2 )
Multiply the numbers
ℎ = − 12

I reported the other answer HAHAHA here is the correct one
Geroge and fred are wanting to make money this summer by mowing lawns they plan to mow as many laws as they can ther goal os to make 400 to buy the newest cinsole they will be chargiing 15 per lawn however they are needling to takes a gallon of gas to mow how many lawns will they need to mow to maoe their goal
Based on the parameters given, the cost of gallon of gas taken to mow wasn't given and isn't available online, However, the procedure to take to reach the final answer will be broken down in the solution.
Answer:
(400 / 15 - x)
Step-by-step explanation:
Given that:
Targeted profit = $400
Amount charged per lawn = $15
The cost of gallon of gas used will be the expense in this scenario:
Profit = Revenue - expenses
The revenue is the entire amount amount including the cost incurred on providing a Certain service.
Expenses = cost of gas
If cost of gas = $x per lawn
The profit made per lawn equals :
Amount charged per lawn - expense
15 - x
Number of lawns they'll have to mow to earn 400 in profit :
Number of lawns = targeted profit / profit per lawn
Number of Lawns = (400 / 15 - x)
Once the value of x is known, you can substitute into the equation to obtain an exact number for the number of lawn that would have to be mowed to make a profit of $400

Write and solve two division expressions that have a negative quotient. Use the fractions − 2 /3 , 5/ 6 , and − 1 4 . Show your work.
Answer:
By remembering a few simple rules, you will be able to divide any negative fraction problem you come across. Ignore the negative sign at first and multiply one fraction by the reciprocal of the other. The reciprocal is attained by simply flipping the numerator and the denominator.

Line segment AB has endpoints A (-4, 4) and B (2, 4). What is the length of line segment AB?
Step-by-step explanation:
the distance is sqrt ( (-6)^2 + (-12)^2) = sqrt( 36 + 144) = sqrt( 180) = sqrt(36*5) = 6 * sqrt(5)
2/(2+4) = 2/6 = 1/3
-2 + (1/3)*6*sqrt(5) = -2 + 2* sqrt(5)
6 + (1/3)*6*sqrt(5) = 6 + 2* sqrt(5)

Factor the following expression completely. Write your answer in simplest form.
−m^7−10m^6−25m^5
Answer:
-m^5 (m+5)^2
Step-by-step explanation:
−m^7−10m^6−25m^5
Factor out the greatest common factor, -m^5
-m^5( m^2 + 10m +25)
We can factor the term inside the parentheses
What two numbers multiply to 25 and add to 10
5*5 =25
5+5= 10
-m^5 ( m+5)(m+5)
-m^5 (m+5)^2
243^0.2x=81^x+5
Could you please help me with the steps to this problem?
Answer:
-20/3
Step-by-step explanation:
First simplify the left side of the equation
243^(1/5x)= (243^1/5)^x
=([tex]\sqrt[5]{243}[/tex] )^x
= 3^x
Now that the left side is simplified, let's move to the right side
81^(x+5)=( [tex]3^{4}[/tex])^(x+5) simplify 81 to base 3^4
=[tex]x^{4(x+5)[/tex] use the product of powers property to multiply the exponents together
=[tex]x^{4x+20[/tex]
With both sides simplified, let's rewrite the equation, this time in simplified terms
[tex]3^{x}[/tex]=[tex]3^{4x+20}[/tex]
x=4x+20 because both the bases are same, their exponential value must also be equal
-3x=20 solve the algebraic equation for x
x=[tex]-\frac{20}{3}[/tex]

2. How many ounces of Ceylon tea worth $1.50 per ounce
and how many ounces of Formosa tea worth $2.00 per
ounce must be mixed to obtain a mixture of 8 ounces
that is worth $1.85 per ounce?
Answer: How many ounces of ceylon tea worth 1.50 per ounce and how many ounces of formosa tea worth 2.00 per ounce must be mixed to obtain a mixture of 8 ounces that is worth 1.85 per ounce
Equation:
1.5c + 2f = 1.85*8
c + f = 8
Modify:
1.5c + 2f = 1.85*8
2c + 2f = 16
Subtract and solve for "c":
0.5c = 1.2
c = 2.4 ounces (amt. of ceylon tea needed)
Solve for "f":: c + f = 8, so f = 5.2 ounces

1) Use the formula of rectangular prism: width x height x length
2) Use the formula of triangular prism: (Base x height x length) ÷ 2
3) Use the formula of cylinder: π x [tex]radius^{2}[/tex] x height
--------------------------------------------------------------------------------------------------
1)
width = 5 cmheight = 9 cmlength = 23 cmwidth x height x length
= 5 x 9 x 23
= 1035
answer: 1035 cubic centimeters------------------------------------------------------------------------------------------------
2)
Base = 5 inheight = 4 inlength = 20 in(Base x height x length) ÷ 2
= (5 x 4 x 20) ÷ 2
= 400 ÷ 2
= 200
answer: 200 cubic inches------------------------------------------------------------------------------------------------
3)
