The turtle's depth relative to sea level after the first minute is 1.2 yards.

Given,

The depth where the turtle descends, d = -3/4 yards

The speed of turtle relative to sea level, t = 5/8 minutes.

We have to find the turtle's depth relative to sea level after the first minute.

The rate at which the turtle descends, r = d/t

r = d/t

r = (-3/4) / (5/8)

r = -3/4 × 8/5

r = -6/5 yards/minute

r = -1.2 yards/min

Now, the depth of turtle after the one minute, D = rt

Where, r = -1.2 yards/min and t = 1 min

Then,

D = -1.2 × 1 = -1.2 yards

That is,

The turtle's depth relative to sea level after the first minute is 1.2 yards

Answer: the maximum profit per holiday is 31050 pesos

Step-by-step explanation:

y=-0,015x²+45x-2700   (1)

It`s a quadratic equation like y=ax+bx+c

Therefore, the value of x at which y is maximal is:

[tex]\displaystyle\\x=\frac{-b}{2a} \\\\x=\frac{-45}{2(-0.015)} \\\\x=\frac{-45}{-0.03} \\\\x=\frac{45(100)}{0.03(100)}\\\\x=\frac{4500}{3} \\\\x=\frac{3(1500)}{3} \\\\x=1500[/tex]

Substitute the value of x into equation (1):

[tex]y=-0,015(1500^2)+45(1500)-2700\\\\y=-0.015(15*10^2)^2+67500-2700\\\\y=-0.015(15^2)(10^4)+64800\\\\y=-0,015*225*10^4+64800\\\\y=-150*225+64800\\\\y=-33750+64800\\\\y=31050 \ pesos[/tex]

The percentage of monthly budget should Jacob allocate for rent is 27.7%.

For the given question;

Jacob's two week earning is $1,350.

Jacob's one week earning will be $1,350/2 = $675.

Considering there are 5 weeks in a months.

Jacob's one month earning will be $675×5 = $3,375.

The total monthly rent = $936.

Let 'x' be the percentage Jacob pay for the rent.

Then,

x% of 3,375 = 936

Simplifying the expression.

3,375x/100 = 936

x = 93,600/3,375

x = 27.7 %

Thus, the percentage of monthly budget should Jacob allocate for rent is 27.7%.

Answer:B - 24

Step-by-step explanation:

12 x 2 = 24
24 x 1 = 24

The slope of the line perpendicular to the line whose equation 2x+3y= 24 is 3/2

The equation of the line is

2x+3y = 24

The standard form of the linear equation is

Ax + By = C

Where A, B and C are the integers

By comparing the standard form of the linear equation with the given equation

A = 2

B = 3

C = 24

The slope of the equation in standard form m = - A/B

Substitute the values in the equation

The slope of the equation in standard form m = -2/3

Slope of a line perpendicular to the line = -1/m

= -1/(-2/3)

= 3/2

Hence, the slope of the line perpendicular to the line whose equation 2x+3y= 24 is 3/2

Daisy has two measuring jugs, A and B. The volume of each measuring jug will be A and B will be 500 ml and 400 ml.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Daisy has two measuring jugs, A and B, that together have a capacity of 900 ml, A jug of water is filled by Daisy. Afterward, she transfers water from jug A into jug B. Following this, jug A has 500 ml of water left.

Total volume = volume in jug A + volume in Jug B

If there are 500 ml of water remaining in jug A.

900 ml = 500 ml + volume in Jug B

volume in Jug B = 900 - 500

volume in Jug B = 400 ml

The simplified expression of (5x⁶y²)³ is 125[tex]x^{18}y^{6}[/tex] which is expressed using the positive exponents.​

A positive exponent indicates that the base should be multiplied by that many.

For instance, 10 should be multiplied by 10x10x10, or 1000, if the number is 103. The variable x should be multiplied by itself nine times if the variable is x raised to 9.

It is possible to simplify exponents by putting exponent-containing algebraic formulas into a simpler form that prevents further simplification.

Answer:

The sum of the interior angles of a polygon is given by the formula:

Sum = (n - 2)180

where n is the number of sides of the polygon

Since the polygon is a three-sided polygon, n = 3

Sum = (3 - 2)180

Sum = 1 x 180

Sum = 180

Answer:

115°

Step-by-step explanation:

The sum of the three angles in a triangle is always 180°

m∠A + m∠B + m∠C = 180°

m∠B = 180 - m∠A - m∠C

m∠B = 180 - 30 - 35 = 115

The percentage of New Yorks state teachers that earn between $7000 and $75000 is 13.63%.

Let the salary of the teachers be represented as x.

Mean = $81410

Standard deviation = $9500

In this case, the probability for normal distribution will be used. This is illustrated as P(a < Z < b).

where a = lower number.

b = higher number

Therefore, the probability of earning the amount will be:

P(70000 < X < 75000)

= P[(70000 - 81410/9500) < Z < (75000 - 81410/9500)

= P(-1.20 < Z < -0.67)

Using the z table to look for the value

= 0.8849 - 0.7486

= 0.1363

= 13.63%.

Therefore, the probability is 13.63%.

Answer:

A. Yes, Rectangle A is a scaled copy of rectangle B.

B. Yes, Rectangle B is a scaled copy of rectangle A.

C. No, Rectangle A is not a scaled copy of rectangle C.

Step-by-step explanation:

Rectangle A has dimensions 12x8 and Rectangle B has length 15x10.

We see that sides of A and B are proportional because

[tex]\frac{12}{15} = \frac{8}{10}[/tex]

So we say that since sides are proportional A and B are similar or scaled copy of each other.

Since A is smaller and B is bigger, a is 0.8 scaled copy of B. Similarly B has an enlargement scale factor = 1.25 Rectangle C has 30x15, not proportion with sides of A and B. Hence we find that C is neither a scaled copy of A nor B

You have the following equation:

-8(y -7) = 2y + 6

In order to solve for y, proceed as follow:

-8(y -7) = 2y + 6 expand the factor right side

-8y + 56 = 2y + 6 subtract 2y and subtract 56 both sides

-8y - 2y = 6 - 56 simplify

-10y = -50 divide by -10 both sides

y = -50/(-10)

y = 5
