Answer:

5.3

Step-by-step explanation:

We know that the bottom of the ladder is 15 feet from the wall, and it touches the wall 80 feet above the ground.  Imagine it like two points on a graph.  One is at the origin (0,0).  That represents the bottom of the ladder.  The next one is at (80,15), which represents where the top is.  To find slope, we divide rise (y-values) over the run (x-values).  The y value increases by 80, while the x increases by 15.  80 divided by 15 equals about 5.3

Answer:

54,265 fishes

Step-by-step explanation:

The formula for Population decrease =

P(t) = Po × e^-rt

Where

P(t) = Population after time t

Po = Initial population = 95000

r = decrease rate = 4% = 0.04

t = time in years = 14

Hence

P(t) = 95,000 × e ^- 0.04 × 14

P(t) = 95,000 × e^-0.56

P(t) = 54264.861066 fishes

Approximately = 54,265 fishes

The total fish the company caught over the first 14 years, to the nearest whole number is 54,265 fishes

Answer:

7.95$

Step-by-step explanation:

1.87 $ per 1 lb

1.87 * 4.25 = 7.95$

Answer:

$7.95 for 4.25 lbs. of grapes

Step-by-step explanation:

so your going to multiply $1.87 by 4.25 to get the total amount of money needing to be paid in or der to buy the 4.25 lbs. of grapes:

$1.87 * 4.25 = 7.9475

now turning it into money by rounding to the hundredths place:

7.9475 = $7.95

So you would have to pay $7.95 for 4.25 lbs. of grapes but logically you would bring 8 dollars to buy it, but down to the cents it would be $7.95.

Answer:

a = 1

Step-by-step explanation:

Original Equation:

-1 + 8 = 10 - 3a

Add 1 to both sides

8 = 11 - 3a

Subtract 11 from both sides

-3 = -3a

Divide both sides by -3

a = 1

If I am not mistaken the answer is x<-27/2.

Answer:

It is B because it is negative correlation.

Step-by-step explanation:

Everyone keeps saying it's A, but how would it be A if the trend is going down? Make it make sense.

It is B.

Answer:

A rational expression that has the nonpermissible values [tex]x = 0[/tex] and [tex]x = 17[/tex] is [tex]f(x) = \frac{4}{x\cdot (x-17)}[/tex].

Step-by-step explanation:

A rational expression has a nonpermissible value when for a given value of [tex]x[/tex], the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:

[tex]f(x) = \frac{p(x)}{q(x)}[/tex] (1)

Then, the factorized form of [tex]q(x)[/tex] must be:

[tex]q(x) = x\cdot (x-17)[/tex] (2)

If we know that [tex]p(x) = 4[/tex], then the rational expression is:

[tex]f(x) = \frac{4}{x\cdot (x-17)}[/tex] (3)

A rational expression that has the nonpermissible values [tex]x = 0[/tex] and [tex]x = 17[/tex] is [tex]f(x) = \frac{4}{x\cdot (x-17)}[/tex].

Answer:

h = no solution

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

5h + 10 = 5h + 15

Step 2: Solve for h

Here we see that 10 does not equal 15.

∴ h has no solution.

Final Answer: No Solution

Steps/Reasons:

Step 1: Simplify [tex]4h + h + 15[/tex] to [tex]5h + 15[/tex].

[tex]5h + 10 = 5h + 15[/tex]

Step 2: Cancel [tex]5h[/tex] from both sides.

[tex]10 = 15[/tex]

Step 3: Because [tex]10 = 15[/tex] is false, there is no solution.

No Solution

Answer: Small box: $13; Large box: $16

Explanation:

Make two individual equations for Perry and Alberto. Perry's equation would be 7x+12y=283. Alberto's equation would be 8x+6y=200. The best way to find the variables is to change the equations into slope-intercept form. Perry's equation would change to y=-7/12x+283/12 and Albert's equation would change to y=-4/3x+100/3. You can try substituting and plugging -4/3x+100/3 into the other equation, so they equal each other. But, you can also just graph the equation into a graphing calculator or Desmos. When graphing it, the point of intersection should be (13,16), so the cost of a small box tangerines is $13 and a large box of tangerines is $16.

Answer:

Y=3x-2

Step-by-step explanation

Answer:

Step-by-step explanation:

Answer:

Blank 1) 2 1/3 yards : 7 Feet

Blank 2) 1 yards : 3 Feet

Blank 3) 2 yards : 6 Feet

Blank 4) 1.5 yards : 4.5 Feet

Therefore, the constant of proportionality is: k = 3

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get the equation

y ∝ x

y = kx

Here, k is the constant of proportionality.

From the table, taking the first two points to determine the constant of proportionality.

Yards                Feet

1/2                       1.5

1/3                        1

Using the equation

substituting y = 1.5 and x = 1/2

y = kx

k = y/x

k = (1.5) / (1/2)

k = 1.5 / 0.5

k = 3

also substituting  y = 1 and x = 1/3

k = y/x

k = 1 / (1/3)

k = 3

As the constant of proportionality is the same.

Determining Blank 1

Yards = x = 2 1/3 = 7/3

y = blank 1 = Feet ?

k = 3

Using the equation

y = kx

blank 1 = Feet = y = 3 (7/3)

blank 1 = Feet = y = 7

In other words,

When Yards = 2 1/3, then Feet = 7

Determining Blank 2

Feet = y = 3

Blank 2 = x = yards ?

k = 3

Using the equation

y = kx

Blank 2 = x = yards =  y/k    

Blank 2  = x = yards = 3/3

Blank 2 = x = yards = 1

In other words,

When Yards = 1, then Feet = 3

Determining Blank 3

yards = x = 2

Blank 3 = y = Feet ?

k = 3

Using the equation

y = kx

y = Blank 3 = Feet = 3(2)

y = Blank 3 = Feet = 6

In other words,

When Yards = 2, then Feet = 6

Determining Blank 4

Feet = y = 4.5

Blank 4 = x = Yards ?

k = 3

Using the equation

y = kx

x = Blank 4 = y/k

x = Blank 4 = 4.5/3

x = Blank 4 = 1.5

In other words,

When Yards = 1.5, then Feet = 4.5

Summary:

Blank 1) 2 1/3 yards : 7 Feet

Blank 2) 1 yards : 3 Feet

Blank 3) 2 yards : 6 Feet

Blank 4) 1.5 yards : 4.5 Feet

Therefore, the constant of proportionality is: k = 3

Answer:

0.3

Step-by-step explanation:

We use the following rules to round 0.34 to the nearest tenth:

A) If the last digit in the fractional part of 0.34 is less than 5, then simply remove the last the digit of fractional part.

B) If the last digit in the fractional part of 0.34 is 5 or more and the first digit in the fractional part is less than 9, then add 1 to the first digit of the fractional part and remove the second digit.

C) If the last digit in the fractional part of 0.34 is 5 or more and the first digit in the fractional part is 9 then add 1 to the Integer part and make the fractional part 0.

With 0.34, rule A applies and the answer is: 0.3

Answer:

BA = 25.5961

Step-by-step explanation:

To solve for side BA, we need to use the correct trigonometric function that relates (from the perspective of angle B) side AC and BA.

AC is Opposite of angle B

BA is the Hypotenuse

The function we use here is Sine. Sine is:

Sin(θ) = Opposite/Hypotenuse

So we simply substitute our information to solve.

Sin(62) = 22.6/BA

BA = 22.6/Sin(62)

Typing this into our calculator we get:

BA = 25.5961

(This is rounded to 4 decimal places)

Answer: 8/10 × 3/100

3/100 × 8/10

Step-by-step explanation:

To be able to solve this question, we need to convert the decimals to Fractions. After they've bee converted to Fractions, we can then look at the options given and see the correct option.

0.8 will be 8/10 when converted to a fraction while 0.03 will be 3/100. Therefore, the correct option will be:

= 8/10 × 3/100 or 3/100 × 8/10.

Therefore, options B and E are correct.
