Complete question :
Ann, Brian and Carol share the cost of a car. Ann pays 2/5 of the cost, Brian pays 1/3 and Carol pays the rest.
a) What fraction of the cost does Carol pay?
b) Ann pays $1600 more than Brian. Find the total cost of the car.
Answer:
4/ 15
8000
Step-by-step explanation:
A)
Fraction carol paid :
Total fraction = 1/1
Fraction paid by Ann and Brian = (2/5 +1/3)
(2/5 + 1/3) = (6 + 5) / 15 = 11/15
1 - 11/ 15 = 4/ 15
Ann = 2/5 ; Brian pays 1/3
Ann pay 1600 more than Brian
2/5 - 1/3 = (6 - 5) = 1/5
1/5 of amount = 1600
If :
1/5 = 1600
1 = x
1/5x = 1600
x = 1600 ÷1/5
Total amount = 8000
is 4/3 = 8/6 a proportional?
Answer:
its b
Step-by-step explanation:
b
Answer:
Yes 4/=8/6 are proportional
If you look at the first fraction 4/3 and multiply 2 by the denomenator and numerator it will equal to 8/6 . Now to switch it up 8/6 divided by 2 is 4/3 so yes the t2 fraction are proportional.

Laura earns $115 a month babysitting. If she saves all of the
money she earns in June and July and uses it to buy a bicycle
that cost $158, how much money will she have left?
A. $230,00
B. $43.00
C. $60.00
D. $72.00
Answer:72
Step-by-step explanation:
115+115=230
230-158=72
If you add the 115 a month that she earns from babysitting, then add both the months pay together, than subtract 158(cost of the bicycle) by the total pay, you should get 72$
Answer: D. $72
Step-by-step explanation:
If she earns $115 a month and June and July is a combination of two months then we will have to find the amount she earn toegther in June and July by multiplying 2 by $115.
2(115) = 230
She earned $230 in those months, and if the bicycle cost $158 , then we will have to subtract $158 from $230 to find her remaining amount.
$230 - $158 = $72

The value of the expression b²/c² is 46656.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We can use the given equations to express a, b, c, and d in terms of k:
a/b = b/c = c/d = k
From a/d = 1/216,
we have:
a/d = k² / (c/d)
Substituting k = b/c and simplifying:
a/d = (b/c)² / (c/d)
a/d = b² / (c² x d)
Multiplying both sides by c².
(a/d) x c² = b² / d
Substituting k = c/d:
(a/d) x c² = b² / k
Substituting a/b = k and solving for b²/c².
a/b = k
a = k x b
b = a/k
b² = a²/k²
(b²/c²) = (a²/k²) / (a²/k² x (d/c)²)
(b²/c²) = 1 / (d²/k²)
Substituting k = c/d and simplifying:
(b²/c²) = d²
Substituting a/d = 1/216:
(b²/c²) = (216²)
Therefore,
The value of the expression b²/c² is 46656.

A spherical hot air balloon has a diameter of 55 feet when the balloon is inflated the radius increases at a rate of 1.5 feet per minute. approximately how long will it take to inflate a balloon 2/3 of its maximum volume? use. 3.14 as pie
Answer: 46.90mins
Step-by-step explanation:
The given data:
The diameter of the balloon = 55 feet
The rate of increase of the radius of the balloon when inflated = 1.5 feet/min.
Solution:
dr/dt = 1.5 feet per minute = 1.5 ft/min
V = 4/3·π·r³
The maximum volume of the balloon
= 4/3 × 3.14 × 55³
= 696556.67 ft³
When the volume 2/3 the maximum volume
= 2/3 × 696556.67 ft³
= 464371.11 ft³
The radius, r₂ at the point is
= 4/3·π·r₂³
= 464371.11 ft³
r₂³ = 464371.11 ft³ × 3/4
= 348278.33 ft³
348278.333333
r₂ = ∛(348278.33 ft³) ≈ 70.36 ft
The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)
The time for the radius to increase to the
above length
Time taken for the radius to increase the length.
= is 70.369 ft/(1.5 ft/min)
= 46.90 minutes
46.90mins is the time taken to inflate the balloon.

Xavier ran 2.5 miles in 12 minutes. How long will it take him to run 1 mile?
Answer:
4.8 minutes
Step-by-step explanation:
2.5/2.5=1
so
12/2.5=4.8
Answer:
4.8 minutes per mile
Step-by-step explanation:
Let mi be miles
Let min be minutes
2.5mi = 12min
Divide by side by the mile to get the unit rate
2.5/2.5 = 12/2.5
You will get 1 = 4.8
Describe the relationship between using the Distributive Property to simplify an expression and to factor an expression. Give an example to justify your answer.
Answer:
Step-by-step explanation:
To factor a polynomial, first identify the greatest common factor of the monomial terms. Then use the Distributive Property to rewrite the polynomial as the product of the GCF and the other parts of the polynomial. (Remember, the distributive property says that a(b + c) = a • b + a • c.)
To factor a polynomial, first identify the greatest common factor of the monomial terms. Then use the Distributive Property to rewrite the polynomial as the product of the GCF and the other parts of the polynomial
What is Number system?A number system is defined as a system of writing to express numbers.
The relationship between using the Distributive Property to simplify an expression and to factor an expression is given here.
The distributive property tells that
a(b-c)=ab-ac and a(b+c)=ab+ac
It means you can separate the common term and represent it as the factor.
Example 12x+4y
The factors of 12 are 4,3
The factor of 4 are 1,2,4
The common factor is 4.
12x+4y=4(3x+y)
We taken out the common factor and has distributive property.
Hence To factor a polynomial, first identify the greatest common factor of the monomial terms. Then use the Distributive Property to rewrite the polynomial as the product of the GCF and the other parts of the polynomial

Answer:
x=3
Step-by-step explanation:
The triangle has angles 30,60,90
In this type of right triangle, the ratio of the sides is 1:square root of 3:2
In this type of triangle, the square root of 3 is equal to the 1 in the ratio above because it is across from the angle 30
With this, we multiply the ratio at the top by the square root of 3
since x is across the angle 60, we multiply square root of 3 by the square root of 3 which equals 3.

y is inversely proportional to x. Given that y = 12 and x = 6. Find the value of y when x = 8.
Answer:
9
Step-by-step explanation:
formula for inverse proportion is y = [tex]\frac{k}{x}[/tex]
k is the constant of probability
to find k,
y is 12, x is 6
12 = [tex]\frac{k}{6}[/tex]
so x = 12 × 6
∴ k is 72
so y = [tex]\frac{72}{8}[/tex]
∴ y is 9
