A cheetah can run 18.75 miles in 1/4 hours. What is its speed in miles per hour?

The rates that are equivalent to the rate Rosario paid are $0.80 for 1 pound, $7.50 for 9 pounds, and $10.00 for 12 pounds​.

What are the rates?

A rate is a unique ratio where the two words are expressed in several units.

Rate formula

r = d/t

Here, we calculate different rates

a. Per pound price of apples = Total cost / total weights of apples

                                             = 0.80 / 1 = $0.80

Cost of 3 pounds of apples = 3 × 0.80 = $2.4

b. Per pound cost of apples = Total cost / total weights of apples

                                               = 14.50 / 5  = $2.9

Cost of 3 pounds of apples = 3 × 2.9 = $8.7

c. Per pound cost of apples = Total cost / total weights of apples

                                               = 7.50 / 9 = $0.833

Cost of 3 pounds of apples = 3 × 0.833 = $2.49

d. Per pound cost of apples = Total cost / total weights of apples

                                              = 9.60 / 11 = $0.872

Cost of 3 pounds of apples = 3 × 0.872 = $2.61

e. Per pound cost of apples = Total cost / total weights of apples

                                               = 10 / 12 = $0.833

Cost of 3 pounds of apples = 3 × 0.833 = $2.49

Hence, The rates that are equivalent to the rate Rosario paid are $0.80 for 1 pound, $7.50 for 9 pounds, and $10.00 for 12 pounds​.

Answer:

Step-by-step explanation:

this seems tough, but,  remember the formulas  ,  point slope  and how to find M ( slope)  and this gets much easier.

let's use the point-slope formula to get the  slope-intercept formula

from my memory,  which you can also memorize

y-y1=m(x-x1)   (point-slope formula)

we are given the slope m = -2

and we're given a point  P(x1,y1)  as  ( -1,-4)

plug this info into our plug and play formula  :P

y-(-4) = (-2)(x-(-1))    : note all the careful attention to minus signs

y+4 = (-2)(x+1)

y+4 = -2x -2

y = -2x -2 -4

y =-2x-6   (slope-intercept formula  y = mx +b)

y= -2x + (-6)

a. The value of 9.9² × 1.79 is 175.44.

b. The value of ✓97.5 + 1.96 is 11.83

An exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.

In this case, the value of 9.9² × 1.79 will be:

= 9.9² × 1.79

= 98.01 × 1.79

= 175.44

The value of ✓97.5 + 1.96 will be:

= ✓97.5 + 1.96

= 9.87 + 1.96

= 11.83

Step-by-step explanation:

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. Each of these equations on their own could have infinite possible solutions.

The system of equations for determining the dollar amount of  phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200

A commission is defined as the compensation paid to a person or entity based on the sale of a product. It is calculated on a percentage basis

Given:

Phone sales commission = 4%

Computer sales commission = 5%

Total commission = $129

Let Sc and Sp represent the dollar amount of phone sales and computer sales respectively

If Houa had $600 more in computer sales than in phone sales, the equation can be written as:

Sc = Sp + 600

Since Houa earns a 4% commission on phone sales and a 5% commission on computer sales, and a total commission of $129. Thus, the equation for the commission can be written as:

0.05Sc + 0.04Sp = 1200

Note:  5% = 5/100 = 0.05 and  4% = 4/100 = 0.04

Therefore, the system of equations for determining phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200

The value of Y = 17.77 when X = 3, and the value of Y = 16 when X = 3

The equation which represents "Y varies inversely as the square of X"  can be written as:

Y = k/X² where "k" is a constant.

Substitute the values of  X=4 and Y= 10 in the variation equation and solve for k:

⇒ 10 = k/(4)²

⇒ 10 = k/16

⇒ k = 160

The variation equation :

⇒ Y = 160/X²

Substitute the values of X = 3 in the above equation and solve for Y:

⇒ Y = 160/(3)²

⇒ Y = 160/9

⇒ Y = 17.77

Thus, the value of Y = 17.77 when X = 3

The equation which represents "Y Varies inversely as X"  can be written as:

Y = k/X where "k" is a constant.

Substitute the values of Y=8 and X=6 in the variation equation and solve for k:

⇒ 8 = k/(6)

⇒ k = 48

The variation equation :

⇒ Y = 48/X

Substitute the values of X = 3 in the above equation and solve for Y:

⇒ Y = 48/(3)

⇒ Y = 16

Thus, the value of Y = 16 when X = 3

Reasoning is not accurate because we cannot take 79.4 and 0.815 has cluster estimates of 8.

Given:

A student estimated the sum 7.95 + 8.11 + 78.5 + 8.05 + 79.4 + 0.815 as: All the numbers begin with a 7 or 8, so use cluster estimation. 8 + 8 + 80 + 8 + 80 + 0.8 = 184.8  

7.95 + 8.11 + 78.5 + 8.05 + 79.4 + 0.815

8 + 8 + 80 + 8 + 80+ 0.8 = 184.8  

Cluster estimation is  used to estimate sums and products when the numbers being  added or multiplied cluster near/ close in value to a single number.

Here 79.4 does not cluster around 8

Answer:

  $7

Step-by-step explanation:

You want to know the cost of each friend's meal if 5 friends spend $41 on their food, which includes a $6 delivery charge.

For 'a' friends spending 'x' on each meal, the total cost is ...

  6 + ax = 41

Solving for x, we have ...

  ax = 41 -6 = 35

  x = 35/a

When the number of friends is a = 5, the cost of a meal is ...

  x = 35/5 = 7

The cost of each friend's mean when the number of friends is 5 is $7.

The particle will move to the right for t > a .

In the question ,

it is given that ,

a particle moves along the x axis , such that at any time t ≥ 0 ,

its position is given by the equation

x(t) = 12(a−t)²  ,

where a is = positive constant

to find value of the particle moves right ,

we differentiate x(t) , with respect to "x" .

x'(t) = 12×2(a - t)×(-1)

v(t) = -24(a-t)        ..... because x'(t) = v(t)

for particle to move right , v(t) > 0 .

-24(a-t) > 0

dividing both sides by "-24" , we get

a - t < 0

a < t

t > a .

Therefore , The particle will move to the right for t > a .

The coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3 are [-3.5, -2].

In this exercise, line ratio would be used to determine the coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3.

Mathematically, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical expression:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Given the following parameters:

Substituting the given parameters into the line ratio formula, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(5(-2) + 3(-6))/(5 + 3)],  [(5(-8) + 3(8))/(5 + 3)]

P(x, y) = [(-10 + (-18))/(5 + 3)],  [(-40 + 3(8))/(5 + 3)]

P(x, y) = [(-10 - 18)/(8)],  [(-40 + 24)/(8)]

P(x, y) = [(-28)/(8)],  [(-16)/(8)]

P(x, y) = [-3.5, -2]

The Area of a rectangle is calculated by multiplying the length by the width.

A = L x W

We have given that area of rectangle is 1,000 m²

1000 = W× L => W = 1000/L ---(1)

The circumference of rectangle is twice the sum of the dimensions. That is,

P = 2L + 2(1000/L)

Now, it is provided that perimeter is minimum so, we differentiate perimeter with respect to L then put first order derivative equal to zero.

dP/dL = 2 + 2000(-1/L²) = 0

=> 2-2000/L²=0

=>2000/L²=2

=> L²=2000/2

=> L²= 1000

=> L= 31.622
