Answer:

24 inches

Step-by-step explanation:

we have 4 sides 2 of them are 5 and the other 2 are 7

7 + 7 = 14

and

5 + 5 = 10

Lastly,

10 + 14 = 24

The outside perimeter of the given its width and the length is 24 inches.

A rectangle is a quadrilateral that has two diagonals of equal length that intersect each other. The perimeter of a rectangle is the distance round the rectangle.

Perimeter of a rectangle = 2 x (length + width)

2 x (5 + 7) = 24 inches

Answer:

63miles/hour=63miles/[60×60]sec=

0.0175miles/sec

Step-by-step explanation:

B.

AC =BC

2x-6=x+8

2x-x=8+6

x=14

5) AC = 2x-6=2(14)-6=28-6= 22

6) BC = x+8= 14+8= 22

7) AB = AC+BC = 22+22= 44

C.

AC =BC

4x+10=7x-5

4x-7x= -5-10

-3x= -15

x= -15/-3 = 5

8) AC = 4x+10=4(5) +10=20+10= 30

9) BC = 7x-5= 7(5) -5=35-5= 30

10) AB = AC+BC = 30+30= 60

B) Solution

AC = BC

→ 2x-6 = x+8

→ 2x-x = 8+6

→ x = 14

5:- AC = 2x-6 = 2(14)-6 = 28-6 = 22

6:- BC = x+8 = 14+8 = 22

7:- AB = AC+BC = 22+22 = 44

C) Solution

AC = BC

→ 4x+10 = 7x-5

→ 4x-7x = -5-10

→ -3x = -15

→ x = -15/-3

→ x = 5

8:- AC = 4x+10 = 4(5) +10 = 20+10 = 30

9:- BC = 7x-5 = 7(5)-5 = 35-5 = 30

10:- AB = AC+BC = 30+30 = 60

Answer:

The cost in 7 years will be of $384.69.

Step-by-step explanation:

Equation for exponential decay:

The equation for an amount after t years is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial value and r is the decay rate.

The cost of High Definition television now averages $1200, but the cost is decreasing by about 15% percent per year.

This means that [tex]A(0) = 1200, r = 0.15[/tex]. So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 1200(1-0.15)^t[/tex]

[tex]A(t) = 1200(0.85)^t[/tex]

What will the cost be in 7 years?

This is A(7).

[tex]A(t) = 1200(0.85)^t[/tex]

[tex]A(7) = 1200(0.85)^7 = 384.69[/tex]

The cost in 7 years will be of $384.69.

Answer:

x = 6/-a

Step-by-step explanation:

To solve for x, you need to isolate it one one side of the equal sign.

-ax - 20 = -14

First, add 20 to both sides of the equal sign

-ax = 6

Then, divide both sides by -a

x = 6/-a = -6/a

Answer:

There is no greatest power of 3 that is divisible of 100.

Step-by-step explanation:

Since any number can always be divisible of 100, there would be no greatest power of 3 that is divisible of 100 since the powers can go on and on forever without stopping, and all powers of 3 is able to be divided by 100.

Answer:

The window should be positioned 4 1/8 feet far from each edge of the wall.

Step-by-step explanation:

Since a construction crew is placing a square in a wall for a new window, which is 3 1/8 feet wide, while the wall has a length of 11 3/8 feet, and the crew wants to position the window at the center of the wall, to determine how far from each edge of the wall should the window be positioned, the following calculation must be performed:

1/8 = 0.125

3/8 = 0.375

(11,375 - 3,125) / 2 = X

8.25 / 2 = X

4.125 = X

Therefore, the window should be positioned 4 1/8 feet far from each edge of the wall.

Answer:

C

Step-by-step explanation:

We want to find ratio of the area of the shaded region to the total area of the square.

First, we can find the total area of the square. Since QR = 7, each side of the square measures 7. Therefore, its area is:

[tex]A=(7)^2=49\text{ units}^2[/tex]

Instead of finding the shaded area, we can find the areas that are not shaded. Subtracting that into the total area will then give us the shaded area.

QRP is a triangle. Since PQRS is a square, QR = 7 = RS = SP = PQ.

So, the area of ΔQRP is:

[tex]\displaystyle A_{\Delta QRP}=\frac{1}{2}(7)(7)=24.5[/tex]

UTS is also a triangle. We are given that RU = US and PT = TS. So, Points U and T bisect RS and SP, respectively. Since RS = SP = 7, RU = US = PT = TS = 3.5. So, the area of ΔUTS is:

[tex]\displaystyle A_{\Delta UTS}=\frac{1}{2}(3.5)(3.5)=6.125[/tex]

Therefore, the total area of the white region is:

[tex]A_{\text{white}}=6.125+24.5=30.625[/tex]

Thus, the shaded region is:

[tex]A_{\text{shaded}}=49-30.625=18.375[/tex]

Then the ratio of the shaded region to the total area of the square will be:

[tex]\displaystyle R_{\text{shaded:total}}=\frac{18.375}{49}=\frac{3}{8}[/tex]

Our answer is C.

Answer:

56.924

Step-by-step explanation:

Step-by-step explanation:

Change the problem into something you recognize

7% = 7 x 10^-2 = 0.07

Multiply by this decimal

53.20 x 0.07 = a

Then add this to the original

53.20 + a

Solution :

Given :

[tex]$\mu = 6883$[/tex]

[tex]$s=2518$[/tex]

n = 40

[tex]$\overline x = 5980$[/tex]

Therefore, determining the null hypothesis and alternate hypothesis is :

[tex]$H_0: \mu = 6883$[/tex]

[tex]$H_a: \mu < 6883$[/tex]

The value of the test statistics is :

[tex]$t=\frac{\overline x - \mu}{s/\sqrt n}$[/tex]

[tex]$t=\frac{5980 - 6883}{2518/\sqrt 40}$[/tex]

[tex]$t \approx -2.27$[/tex]

So, df =  n - 1

          = 40 - 1

          = 39

∴  0.01 < P < 0.025

If the P value is less than α = 0.03, we reject the null hypothesis. Therefore, we conclude that mean annual Medicare spending in Indianapolis is lower than the national mean.

Using the value of [tex]$\alpha = 0.03$[/tex], the critical value of for the test statistics is 2.17

There we reject the null hypothesis. And thus we conclude that the mean annual Medicare spending in Indianapolis is lower than the national mean.

Answer:

B.   3/2

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals

The negative reciprocals of -2/3

is 3/2

The area between the curve and x-axis is 6/7 units²

How can one find out the area between a curve and x-axis using integrals?

By performing a definite integral between the two locations, one can determine the area under a curve between two points. Integrate y = f(x) between the limits of a and b to determine the area under the curve y = f(x) between x = a and x = b. Areas below the x-axis will have a negative result, while those above the x-axis will have a positive result.

Solution:

Given,

curve y= 3x⁶

x-axis interval = ₋1 to 1

area between the curve and the x-axis is limits(-1 to 1) ∫3x⁶

limits(-1 to 1) 3∫x⁶

limits(-1 to 1) 3∫x⁷/7

3[2/7]

6/7 units²

Hence we get the answer as 6/7 units².
