Answer:

135 Miles

Step-by-step explanation:

Answer:

At the nearest mile, stations B and C are 75 miles apart.

Step-by-step explanation:

In the attached image we can see all the three stations. The closest distance between stations B and C would be a straight line that can be calculate using the Cosine Rule:

[tex](BC)^2=(AB)^2+(AC)^2-2(AB)(BC)cos(\alpha)[/tex]}

Where:

AB is the distance between stations A and B

AC is the distance between stations A and C

α is the angle formed between the AC and AB railway lines

[tex](BC)^2=(105)^2+(85)^2-2(105)(85)cos(45)[/tex]

[tex]BC=75.02 miles[/tex]

So, at the nearest mile, stations B and C are 75 miles apart.

Answer:

Your answer would require a 7 in the hundreds place

Step-by-step explanation:

1,273

The 1 is in the thousands place.  1 * 1000

The 2 is in the hundreds place.  2 * 100

The 7 in in the tens place.  7 * 10

 The 3 is in the ones place.  1 * 1

To get from 10 to 100, we would multiply by 10, so to get from the tens place to the hundreds place is 10 times greater.

Your answer would require a 7 in the hundreds place

In the number system, each place to the left is ten times the place to its right. Therefore, for the value of the 7 to be ten times greater than the 7 in 1,273, it must be in the tens place, such as in numbers like 702, 770, or 170.

The value of a digit in a number depends on its place or position. In the number system, each place is ten times the place to its right. Therefore, in the number 1,273, the value of the 7 is simply 7 (because it's in the units place). However, for the 7 in the new number to be ten times greater than the 7 in 1,273, it must be in tens place. Therefore, the new number could be 7x10 = 70 (with the 7 in the tens place). So, any number with 70 in the tens place (like 702, 770, or 170) has a 7 that's ten times the 7 in 1,273.

Answer:

The answer to number 1 is A.

Step-by-step explanation:

To find this answer, I made 1 1/3 into one big fraction. I multiplied the denominator by the whole number (3x1) and then added that product to the numerator. (3+1). The new fraction is now 4/3 (you keep the denominator the same). The next step is to multiply 4/3 by 3/8. When multiplying fractions, you multiply straight across (the numerator by the numerator, and the denominator by the denominator). Your answer is now 12/24. The final step is to simplify the answer. Since 12 is half of 24, the answer is 1/2.

Answer: About 16

Step-by-step explanation:

Given : The length of the ramp = 500 cm

The circumference of the wheel = 32 cm

We know that the number of rotations made by a wheel is given by :-

[tex]\text{No. of rotations}=\text{Length of the ramp}\div\text{ Circumference of wheel}[/tex]

Therefore , the number of rotations made by each wheel = [tex]500\div32[/tex]

[tex]=15.625\approx16[/tex]  [Rounded to the nearest integer.]

Hence,  each wheel will make about 16 rotations while Shawn is coasting down the ramp.

Answer:

Step-by-step explanation:

Plug in -7 for the variable a.

9x - 6(-7) = -7

Follow PEMDAS. Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x.

Multiply -6 with -7

9x - 6(-7) = -7

9x + 42 = -7

Isolate the variable x. Subtract 42 from both sides

9x + 42 (-42) = -7 (-42)

9x = -49

Divide 9 from both sides

(9x)/9  = (-49)/9

x = (-49)/9

x = ~5.44 (rounded)

We are multiplying 7 together 4 times

7*7*7*7

The exponent represents how many times we are multiplying it together.

7^4

Answer:

[tex]7^4[/tex]

Step-by-step explanation:

A mathematical expression written in the form [tex]a^x[/tex] is said to be an exponential expression where [tex]a[/tex] is a constant called the base and [tex]x[/tex] is a variable.

Here we are given a numerical expression 7.7.7.7 which can also be converted into an exponential expression where base would be 7 while the value of its exponent will be 4 since the number 7 is occurring 4 time.

Therefore, the exponential expression will be [tex]7^4[/tex]

Answer: B. 2/5 of the book.

Answer:

y = 2x+2

Step-by-step explanation:

When we have 2 points, we can find the slope from

m = (y2-y1)/(x2-x1)

   = (6--6)/(2--4)

   = (6+6)/(2+4)

   = 12/6

  = 2

The slope is 2

We can use the point slope form of the equation for a line

y-y1 = m(x-x1)

y-6 = 2(x-2)

We need to get this in slope intercept form

Distribute the 2

y-6 = 2x-4

Add 6 to each side

y-6+6 = 2x-4+6

y = 2x+2

Answer:

y = 2x + 2

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + b ( m is the slope and b the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 4, - 6) and (x₂, y₂ ) = (2, 6)

m = [tex]\frac{6+6}{2+4}[/tex] = [tex]\frac{12}{6}[/tex] = 2, hence

y = 2x + b is the partial equation

to find b substitute either of the 2 points into the partial equation

using (2, 6), then

6 = 4 + b ⇒ b = 6 - 4 = 2

y = 2x + 2 ← equation in slope-intercept form

Answer:

a = 5.81 m

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

where b= 1.5 and c= 6

a^2 +1.5^2 = 6^2

a^2 +2.25 = 36

Subtract 2.25 from each side

a^2 +2.25-2.25 = 36-2.25

a^2 = 33.75

Take the square root of each side

sqrt(a^2) = sqrt(33.75)

a = 5.809475019

We only take the positive root because length must be positive

Answer:

Option C is correct.

(1, 4)

Step-by-step explanation:

A system of equation is given :

2x + 3y =12                 .....[1]

4x + 2y =10                 .....[2]

Multiply equation [1] by 2 both sides we get;

[tex]2(2x+3y) = 2(12)[/tex]

Using distributive property i,e [tex]a \cdot(b+c) = a\cdot b+ a\cdot c[/tex]

4x + 6y = 24                           .....[3]

Subtract equation [2] from [3] to eliminate x we get;

4x + 6y - 4x - 2y= 24 - 10

Combine like terms;

4y = 14

Divide both sides by 4 we get;

y = 3.5

Substitute the value of y in equation [1] we have;

2x + 3(3.5) =12

2x + 10.5 = 12

or

2x = 12 -10.5

2x = 1.5

Divide both sides by 2 we get;

x = 0.75

Solution = (0.75 , 3.5)

Best estimate solution =  (1, 4)

Therefore, the best estimate solution of the given system of equation is, (1, 4)

Answer:

1,4 is the best estimate.

Step-by-step explanation:

No, George do not have enough money for his plan of watching movie and purchase the items. So, the numerical expression is 15 - (9+2.65+2(1.35)+2(1.74)).

Given that, George has $15.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

The numerical expression for the given situation is

15 - (9+2.65+2(1.35)+2(1.74))

= 15 - (9+2.65+2.7+3.48)

= 15 - 17.83

= -2.83

No, George do not have enough money for his plan of watching movie and purchase the items. So, the numerical expression is 15 - (9+2.65+2(1.35)+2(1.74)).

Step-by-step explanation:

First Question

What you need to do here is pick an answer that will result in a decrease. If you have something like 1.3 * e ^ (0.038 * t), what will happen when t = 20

P = 1.3 * e^(0.038*20) = 1.3*e^0.76 = 2.77 which is getting bigger not smaller.

So what you want is something like 1.3 * e^-0.76 = 0.67

So which question is configured that way?

It's either C or D. but which one? It cannot be D. 0.38 is far too big: it does not represent 3.8%

C does represent 3.8% as a decimal. It is the correct answer.

Answer: C

Second Question

Every time she sells a ticket, the total that she gets is 4 more than what she had before.

The variation is a direct one. It is y = k*x. But what is k? Is it 4 or is it 1/4?

Read the first sentence above. She gets 4 dollars more, not 1/4 of a dollar.

C and D are both wrong because those equations think she is getting 1/4 more.

B is wrong because it says that the relationship is inverse. It is not. It is direct.
