The area of a square ice rink is 400 yd.². What is the perimeter of the rink in yards

Answers

Answer 1

Answer:

80 yd^2

Step-by-step explanation:

Since the formula for squares is s^2, we can use this to set up an equation, which is

s^2=400

If we square root this, we get

s=20

The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

Answer:

  x^2 -5x +6 = 0

Step-by-step explanation:

Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...

  (2x -1)(3x -1) = 0   ⇒   roots 1/2, 1/3

Then the factoring of the equation with reciprocal roots is ...

  (x -2)(x -3) = 0

The length and width of a rectangle are in a ratio of 7:11. If the perimeter of the
rectangle is 72 cm. Find the
length and
width of the rectangle.

Answers

Answer:

14cm and 22cm

Step-by-step explanation:

Given parameters:

Perimeter of rectangle  = 72cm

Ratio of length to width  = 7: 11

Unknown:

Length and width of the rectangle  = ?

Solution:

Since the ratio of length to width is 7: 11,

  if the length is 7x , width = 11x

 The perimeter of a rectangle can be obtained using

Perimeter = 2(L + W)

  Insert the parameters and solve;

          72  = 2(7x + 11x )

          72 = 2(18x)

           x  = [tex]\frac{72}{36}[/tex]  = 2

The length = 7x  = 7x2 = 14cm

        width  = 11x = 11 x 2 = 22cm

You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?

Answers

Answer:

$3

Step-by-step explanation:

Because you subtract $23-$11 to get the total you spent on avocados then you divide 12/4 because you bought 4 avocados

Answer:

3 dollars for each avocado.

Step-by-step explanation:

Since you had 23 dollars in the beginning and 11 dollars in the end, subtract to find out how much was used for the avacados.

23-11=12

Next, since you bought 4 avocados, you divide 12 by 4 to find out how much each cost.

12/4=3

Each avocado cost 3 dollars.

You can check by multiplying 3 by 4.

3x4=12

Then, add the 12 dollars spent to the 11 dollars left.

12+11=23 dollars

What is the unit rate?

y=5x

Answers

Answer:

In the equation y=5x the slope (m) is 5, and the y-intercept is the point (0,0) since there is nothing added or subtracted to the 5x, and thus b = 0.

Step-by-step explanation:

measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour,

A zoo collected data on the diving times of turtles. Based on the data, the regression line is j = 0.010 + 2.515x, where x is the time of the dive, in minutes. Based on the regression equation, what is the predicted dive depth in meters at 150 seconds? Give your answer to three decimal places. meter(s) ​

Answers

Answer:

6.298 meters

Step-by-step explanation:

Here, we are told that x is the time of the dive in minutes.

We simply first need to convert 150 seconds to minutes before substitution into the regression formula;

Kindly recall that 60 seconds = 1 minute

So 150 seconds will be 150/60 = 2.5 minutes

We now proceed to substitute into;

j = 0.010 + 2.515(x)

i = 0.010 + 2.515(2.5)

j = 0.010 + 6.2875

j = 6.2975 which go 3 decimal places is 6.298 meters

Using the regression model given, substitution the value of x = 2.5 minutes into the equation, the dive depth obtained ls 6.2975 meters.

Given the regression model :

y = 0.010 + 2.515x

x = time of the dive ; y = dive depth

Converting, x to minutes :

150 seconds = (150 ÷ 60) = 2.5 minutes

The dive depth, y after 150 seconds, can be obtained by substituting the value x = 2.5 into the equation :

y = 0.010 + 2.515(2.5)

y = 0.010 + 6.2875

y = 6.2975

There, the dive depth after 150 seconds will be 6.2975 meters

x = 12

Step-by-step explanation:

30 degrees and 4x+2 are equal to 8+6x

First, write a formula or expression:

30 + 4x+2 = 8+6x

simplify this by collecting like terms

32 + 4x = 8+6x (minus 6x from both sides)

32 - 2x = 8 (minus 32 from both sides)

-2x = -24 (divide by -2)

x = 12

now sub into the formula:

30 + (4 × 12 +2) = 8 + 6 × 12

Jason spent a total of $131 on shirts. Dress shirts cost $28 dollars and T-shirts cost $15 dollars. If he brought 7 shirts how many of each kind did he buy?

Answers

Answer:  28x  + 15y = 131   and x + y =  7   where x is the number of Dress shirt and y is the number of T-shirt.

Step-by-step explanation:

We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.

We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal  131.  Also, he bought 7 total shirts so x plus y has to equal 7.

28x  + 15y = 131  

x + y =  7
