Answer:

a. distance between the base of the mountain and the first car, d = 277 m

b. distance between the base of the mountain and the second car, s = 92 m

c. distance between the two cars = 185 m

Step-by-step explanation:

a. Since the angle of depression is 30°, the interior angle = (90 - 30)° = 60°

Let the distance between the base of the mountain and the first car be d, and height of the mountain = 160 m

tan 60° = d/160 m

d = tan 60° * 160 m

distance between the base of the mountain and the first car, d = 277 m

b. Since the angle of depression is 60°, the interior angle = (90 - 60)° = 30°

Let the distance between the base of the mountain and the second car be s, and height of the mountain = 160 m

tan 30° = s/160 m

s = tan 30° * 160 m

distance between the base of the mountain and the second car, s = 92 m

c. distance between the two cars = 277 - 92

distance between the two cars = 185 m

Answer: x=52

Step-by-step explanation:

Answer: the correct Answer should be B

Step-by-step explanation:

The correct option is slope of the line for restaurant B is 2 times greater than the slope of the line for restaurant A.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given the values of x and y for restaurant A as,

x : 10  20  30

y : 1  2  3

Consider the point (10, 1) and (20, 2).

Slope of the linear relationship of x and y of restaurant A is,

Slope = (2 - 1) / (20 - 10)

          = 1/10

Given the values of x and y for restaurant B as,

x : 25  50  75

y : 5  10  15

Consider the points (25, 5) and (50, 10).

Slope of the linear relationship of x and y of restaurant B is,

Slope = (10 - 5) / (50 - 25)

          = 5 / 25

          = 1/5

          = 2 × 1/10

          = 2 × Slope of line for restaurant A

Hence slope of the line for restaurant B is 2 times the slope of line for restaurant A.

Answer:

-35,000

Step-by-step explanation:

Given that :

Let:

Number of previous year supply = x

Number of supply this year = x - 35,000

The change in the number supplied between for this year and previous year

this year supply - previous year supply

(x - 35,000) - x

x - 35000 - x

= - 35,000

Hence, integer which describes the change in the number of DVDs shipped is - 35,000

153 integers lie between 168 and 15

Answer:

e = 16

Step-by-step explanation:

-5/6e + - 2/3e = -24 (Turn -2/3 into 6th)

-5/6e + -4/6 = -24 (Add -5/6e + -4/6e)

-9/6e = -24 (Divide -9/6 from both sides)

e = 16

Double check:

-5/6(16) + -2/3(16) = -24

-13 1/6 + -10 2/3 = -24

-24 = -24

Answer:

2727000

Step-by-step explanation:

You can calculate it orally.

If numbers are multiplied with 10 we get the same answer as the number but with a zero added at the end . For example 27*10= 270

But if we divide the number ending with a zero with a ten the answer is the same but the zero is removed e.g 1000/10= 100

Similarly you have the numbers

10(10100)*27=

Now breaking the bracket part

10 (1010) 10 *27

100 ( 101)10 *27

1000(2727)

=2727000

Answer:

117.7 years

Step-by-step explanation:

We have half life formula,

A=P[tex](0.5)^{\frac{t}{d} }[/tex]

Where ''t'' is number of years

d is half life period.

We know d=29

Where A=6% =0.06

P= 100%=1

Plug in the known values into the formula.

0.06= 1[tex](0.5)^{\frac{t}{29} }[/tex]

Divide both sides by 1.

It gives,

0.06=[tex](0.5)^{\frac{t}{29} }[/tex]

Take log on both sides

log 0.06= [tex]\frac{t}{29}[/tex] log(0.5)

Divide both sides by log 0.5

4.05889 = [tex]\frac{t}{29}[/tex]

Multiply both sides 29

t =117.7079....

Approximately t= 117.7 years.

Answer:

Step-by-step explanation:

le the total cost be y

and the number of miles be x

the expression for the total can  be modelled linearly as

y=mx+c

given that

c=$40

m=$0.75

for x==60miles

we can substitute into the expression to solve for y we have

y=0.75(60)+40

y=45+40

y=85

The cost to deliver at a distance of 60miles is $85

Answer:

Choice letter C most quickly reveals the y intercept; the y intercept is (0,8).

Step-by-step explanation:

The equations given are all different equations for the same parabola! The one that most quickly provides us with the y intercept is letter C!

Why? Well, letter C is in standard form aka the most basic quadratic formula :

[tex]ax^2+bx+c=0[/tex]

Ironically enough, variable c always states the y intercept in equations as such. Variable c, in this case - is 8. Which means the y intercept is 8!

Now, you'll notice that choice B also mentions + 8 in it's formula, this is true - but in this case it refers to one of the x intercepts (which is actually -8!)

Hope I was of assistance! #SpreadTheLove <3

The y-intercept for the equation is 8, and the equation reveals the intercept most quickly by option C.

A mathematical phrase, rule, or law establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Given  a function in three equivalent forms,

to find the y-intercept,

the y-intercept is the point on the y-axis where the value of x is zero,

f(x) = -1/2(x + 3)² + 25/2

f(x) = -1/2(x - 2)(x + 8)

f(x) = -1/2x² - 3x + 8

to find the y-intercept easily the equation should be in form,

ax² + bx + c

where c is the y-intercept,

only 3rd equation is in the form of ax² + bx + c from where y-intercept can be found easily,

f(0) = 8

Hence y-intercept is 8 and with equation f(x) = -1/2x² - 3x + 8 we can calculate it quickly.

Answer:

10 tickets must be purchased in order for the total cost at carnival M and carnival P to be the same

Step-by-step explanation:

Let the number of tickets be represented by t

Carnival M charges an entrance fee of $7.00 and $0.85 per tkcket for the rides.

$7.00 + $0.85 × t

= 7.00 + 0.85t

Carnival P charges an entrance fee of $12.00 and $0.35 per ticket for the rides.

= $12.00 + $0.35 × t

= 12.00 + 0.35t

How many tickets must be purchased in order for the total cost at carnival M and carnival P to be the same?

Carnival M = Carnival P

7.00 + 0.85t = 12.00 + 0.35t

Collect like terms

= 0.85t - 0.35t = 12.00 - 7.00

= 0.50t = 5

t = 5/0.5

t = 10 tickets.

Therefore, 10 tickets must be purchased in order for the total cost at carnival M and carnival P to be the same.

Answer:

The foreman's error was he divided 3 by 12 = 3 ÷ 12

The correct step would be to divide 12 by 3 = (12÷ 3)

Step-by-step explanation:

The foreman's error was he divided 3 by 12 = 3 ÷ 12

A construction company uses 12 pieces of plywood to make 3 sheds. The foreman will be making 6 sheds next week.

Hence , the correct calculation is:

3 sheds = 12 pieces

1 shed = x

3 × x = 12 × 1

3x = 12

x = 12/3

x = 4 pieces

1 shed requires 4 pieces of plywood

The unit rate of how many pieces of plywood he uses per shed is 4 pieces per shed

Hence, the correct step would be to divide 12 by 3 = (12÷ 3)

The number of pieces required for 6 shed is 4 × 6 sheds

= 24 pieces of plywood

Answer:

$337.50

Step-by-step explanation:

Firstly, we need to get the perimeter of the larger farm.

Since the ratio of the sides of the smaller to

the larger is 4:5, then this will be the ratio of their perimeter too

4/5 = 360/x

4x = 5 * 360

x = (5 * 360)/4

x = 450 yards

Now the cost to dig is $0.75 per yard

For a perimeter of 450, the cost will be 450 * $0.75 = $337.5
