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

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.

Given:

Total number of home runs = 583

Home runs hit by LA Dogerse = 6% of the total home runs

To find:

The number of home runs hit by LA Dogers.

Solution:

We have,

Home runs hit by LA Dogerse = 6% of the total home runs

                               [tex]=\dfrac{6}{100}\times 583[/tex]

                               [tex]=\dfrac{3498}{100}[/tex]

                               [tex]=34.98[/tex]

                               [tex]\approx 35[/tex]

Therefore, LA Dogerse hits about 35 home runs.

Answer:

T(3) = -23°C

Step-by-step explanation:

Constant Rate of Change

Given an initial condition of a variable T, To and a constant rate of change m, it's possible to write a model to predict the value of T in time t:

[tex]T(t)=T_o+mt[/tex]

The initial temperature the scientist measures of a chemical solution is To=-14.06°C.

It's known the temperature decreases at a constant rate of -2.9°C each hour, thus the model is:

[tex]T(t)=-14.06-2.9t[/tex]

Evaluating at t=3 hours:

[tex]T(3)=-14.06-2.9\cdot 3[/tex]

[tex]T(3)=-14.06-8.7[/tex]

T(3) = -22.76°C

Rounding to the nearest whole degree:

T(3) = -23°C

An explicit rule for the nth term of the sequence will be:

[tex]a_n=-4\cdot \:2^{n-1}[/tex]      

Thus, option (A) is true.

Step-by-step explanation:

Given the sequence

[tex]-4, -8, -16, -32, ...[/tex]

A geometric sequence has a constant ratio r and is defined by

[tex]a_n=a_0\cdot r^{n-1}[/tex]

Computing the ratios of all the adjacent terms

[tex]\frac{-8}{-4}=2,\:\quad \frac{-16}{-8}=2,\:\quad \frac{-32}{-16}=2[/tex]

As the ratio 'r' is the same.

so

[tex]r=2[/tex]

as

[tex]a_1=-4[/tex]

Hence, the nth term of the sequence will be:

[tex]a_n=a_0\cdot r^{n-1}[/tex]

substituting the values [tex]r=2[/tex] and [tex]a_1=-4[/tex]

[tex]a_n=-4\cdot \:2^{n-1}[/tex]      

Therefore, an explicit rule for the nth term of the sequence will be:

[tex]a_n=-4\cdot \:2^{n-1}[/tex]      

Thus, option (A) is true.

Answer:

A. The situation is discrete B. i. { x : 0 ≤ x ≤ 6; x ∈ Z} ii. { C = 5x : 0 ≤ C ≤ 30; C ∈ Z}

Step-by-step explanation:

A. The situation is discrete since we have integral values for the amount paid per mile walked. The amount per mile is $5 and is only paid if a complete mile is walked. So, it is a discrete situation.

B. i. Since 0 miles represents 0 distance and the student walks a maximum of 6 miles, let x represent the distance walked. So the domain is 0 ≤ x ≤ 6 where x ∈ Z where Z represent integers.

{ x : 0 ≤ x ≤ 6; x ∈ Z}

ii. Since at 0 miles the amount earned is 0 miles × $5 per mile = $ 0 and at the maximum distance of 6 miles, the amount earned is 6 miles × $5 per mile = $ 30, let C represent the amount donated in dollars. So the range is 0 ≤ C ≤ $ 30 where C = 5x.

{ C = 5x : 0 ≤ C ≤ 30; C ∈ Z}

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.

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.

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
