Answer:

a. 95

b. 86

Step-by-step explanation:

Since you need it quick, no explanation for now.

Answer:

Length of the garden: 95 m

Width of the window: 86 cm

Step-by-step explanation:

Part A:

We can use the equation for area to find the length of the garden.

[tex]Area = Width * Length[/tex]

If we simply divide both sides of the equation by width, we will be solving for lenght:

[tex]\frac{Area}{Width} = Length[/tex]

Now, plug in the known values for the area and width of the garden:

[tex]\frac{6460}{68}=Length[/tex]

[tex]95=Length[/tex]

Part B:

This time, we'll have to use the equation for perimeter:

[tex]Perimeter = [2(Width)]+[2(Length)][/tex]

Because we want to know the width, and already know the perimeter and length we can once again use algebra to solve for the width:

[tex]Perimeter-[2(Length)] = 2(Width)\\\frac{Perimeter-[2(Length)]}{2} =Width[/tex]

Now, simply plug in the values for the perimeter and the length and solve:

[tex]\frac{370-[2(99)]}{2} =Width\\\\\frac{370-198}{2} =Width\\\\\frac{172}{2}=Width\\\\86=Width[/tex]

Therefore, the width of the window is 86 cm.

Answer:

Step-by-step explanation:

When solving a system of equations using substitution, you look for an equation that makes it simple to write an expression for one of the variables in terms of the other(s). Here, the first equation already gives you an expression for x, so it is easiest to substitute for x in the second equation:

  (2y -5) +2y = 4 . . . . . . (2y-5) substituted for x

  4y = 9 . . . . . . . . . . add 5 and simplify

  y = 9/4 . . . . . . . . divide by 4

  x = 2(9/4) -5 = 9/2 -10/2 = -1/2

The solution is (x, y) = (-1/2, 9/4).

Using the probability concept, it is found that they are given by:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Without replacement, there are 4 out of 20, and then 3 out of 19 cards with a 1, hence:

[tex]p = \frac{4}{20} \times \frac{3}{19} = 0.0316[/tex]

0.0316 = 3.16% probability that both cards selected have a 1 without replacement.

With replacement, in each trial, 4 out of 20, hence:

[tex]p = \frac{4}{20} \times \frac{4}{20} = 0.04[/tex]

0.04 = 4% probability that both cards selected have a 1 with replacement.

They watch anime in their room for 5 hours then come back later. Frank is a dad. The "people" is his daughter. IM KIDDING, but more info please i dont really understand

Step-by-step explanation:

because is true (ITS NOT)

In addition to the fact that she has never kept a diary before, Anne Frank finds it strange that someone like her would do so. She also believes that neither she nor anybody else would find interest in a diary kept by a thirteen-year-old schoolgirl.

The residents are given five minutes to gather their belongings when the military break down the annex door. Nothing else may be taken by them. The scene comes to a close as Anne's voice commands Miep to keep her diary secure.

Frank discussed how people saw her in her final journal post, calling herself "a tangle of paradoxes." "As I've told you many times, I'm torn in two," she wrote. One half of myself is full of excitement, exuberance, flippancy, and, most importantly, the capacity to see the lighter side of things.

Thus, Anne Frank finds it strange that someone like her would do so.

Answer:

C = (12, 13)

Step-by-step explanation:

The centre of the rectangle is O.

Find the difference between the x and y-values of O and A:

[tex]O_x-A_x=\dfrac{21}{2}-9=\dfrac32[/tex]

[tex]O_y-A_y=\dfrac{19}{2}-6=\dfrac72[/tex]

Now add those difference to the coordinates of O to find C:

x value of C = [tex]O_x+\dfrac32=\dfrac{21}{2}+\dfrac32=\dfrac{24}{2}=12[/tex]

y value of C = [tex]O_y+\dfrac72=\dfrac{19}{2}+\dfrac72=\dfrac{26}{2}=13[/tex]

Therefore, the coordinates of C = (12, 13)

Answer:

Step-by-step explanation:

In rectangle the diagonals bisect each other. So,O is the midpoint of AC

[tex]Midpoint = \left(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2} \right)\\\\\\x_{1}=9 \ and \ y_{1}=6\\\\\left(\dfrac{9+x_{2}}{2},\dfrac{6+y_{2}}{2} \right) = \left (\dfrac{21}{2},\dfrac{19}{2} \right)[/tex]

Compare the x- coordinates and y- coordinates

[tex]\dfrac{9+x_{2}}{2}=\dfrac{21}{2} \ ; \ \dfrac{6+y_{2}}{2}=\dfrac{19}{2}\\\\\\9+x_{2}=\dfrac{21}{2}*2 \ ; \ 6 +y_{2}=\dfrac{19}{2}*2[/tex]

9 + x₂ = 21         ;  6 +y₂ = 19

     x₂ = 21 -9     ;       y₂ = 19 - 6

     x₂ = 12         ;        y₂ = 13

Using a system of equations, it is found that the usual waiting time for the bumper cars is of 7.5 min.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

The waiting time for the roller coaster is usually 3 times as long as the waiting time for the bumper cars, hence:

x = 3y

The park's website says that visitors who go on both rides should expect to wait a total of 30 min, hence:

x + y = 30

Since x = 3y:

3y + y = 30

4y = 30

y = 30/4

y = 7.5.

The usual waiting time for the bumper cars is of 7.5 min.

Answer:

Answer: 1/3

Step-by-step explanation:

The probability of getting tails when tossing a coin is 1/2

The probability of rolling a number greater than 2 is 4 (3 4 5 6)

So 4/6 or 2/3 of the time is the probability of throwing the die and getting a number greater than 2.

The combined probability of getting both is 1/2 * 2/3 = 2/6 or 1/3

A. 68 feet ( the length of the outer curve to the nearest foot

Option C is correct, the the length of the outer curve to the nearest foot is 86 feet.

The formula for length of arc to find the length of the outer curve.

Thus; Arc Length = radius ×angle

We are given;

Radius = 70 ft

Angle = 70° = 70 × π/180 radians

Thus;

Arc length = 70 × (70 × π/180)

Arc length = 86 ft

Therefore, the outer curve is 86 feet long. Option C is correct.

8 1/2 divided by 2 1/4 = 3 7/9 inches

Answer:

Step-by-step explanation:

(a -b)² = a² - 2ab + b²

Here, a = 6x & b = 5

Area of a square = side * side

                            = (6x - 5)*(6x - 5)

                            = (6x - 5)²

                            = (6x)² - 2*6x*5 + 5²

                             = 36x² - 60x + 25

Answer:

H

Step-by-step explanation:

So when finding the area you need to square the radius. In the problem she only multiplied it by two. so she needs to do 49×3.14.
