which set of points below lie on a line that is parallel to AB?

a=(-4,5) and (6,-2)
b=(-5,4) and (5,-2)
c=(1,0) and (5,2)
d=(-3,-4) and (0,1)​

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

Answer:

68

Step-by-step explanation:

multiply 17 by 4

Answer:

68%

Step-by-step explanation:

25 x 4= 100

17 x 4= 68

so 17/25 is equal to 68/100

Hope this helps!

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.

I hope this makes sense

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

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

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:

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

The value of the expression b²/c² is 46656.

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.

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.
