Answer:

2496 cm sq.

Step-by-step explanation:

Length equals 52cm and Perimeter is 200cm.

Area = Length x Breadth (or Width).

To find the area we have to first find the breadth.

2 x (Length + Breadth) = Perimeter.

Substituting what's given in the question, we get:-

2 x ( 52 + Breadth) = 200

52 + Breadth = [tex]\frac{200}{2}[/tex]

52 + Breadth = 100

Breadth = 100 - 52

Breadth = 48cm.

So, Area equals-------->

Length x Breadth

= 52 x 48

Area = 2496 cm sq.

Answer:

C

Step-by-step explanation:

The answer is c because when 2, -1 is plugged into the equation, you get

.5(2) - 2(-1) >/= 3

when solved -

1 + 2 >/= 3 -

3 >/= 3

and this is in the solution set because three is equal than or greater to three

Answer:

Option A.

Step-by-step explanation:

Function f:

For x between -1 and 2, the values of f(x) increase, which means that f(x) is increasing.

Function g:

[tex]g(x) = -18(\frac{1}{3})^x + 2[/tex]

Between -1 and 2:

[tex]g(-1) = -18(\frac{1}{3})^{-1} + 2 = -18*3 + 2 = -54 + 2 = -52[/tex]

[tex]g(0) = -18(\frac{1}{3})^{0} + 2 = -18*1 + 2 = -18 + 2 = -16[/tex]

[tex]g(1) = -18(\frac{1}{3})^{1} + 2 = -18*\frac{1}{3} + 2 = -6 + 2 = -4[/tex]

[tex]g(2) = -18(\frac{1}{3})^{2} + 2 = -18*\frac{1}{9} + 2 = -2 + 2 = 0[/tex]

Both are increasing.

However, g starts with a lower value, and finishes with a higher value, which means that function g increases at a faster average rate, and the correct answer is given by option A.

Answer:

Every day Dajuan will paint 14.5 square feet of the wall.

Step-by-step explanation:

Since Dajuan is painting a mural on a rectangular wall, which measures 14.5 feet long and 10 feet wide, and so far, his mural covers 60% of the wall, and Dajuan will paint the remaining part of the wall over the next four days, painting the same amount of the wall, in square feet, on each of those four days, to determine how much of the wall, in square feet, will Dajuan paint on each of the next four days, the following calculation must be performed:

((14.5 x 10) x 0.4) / 4 = X

(145 x 0.4) / 4 = X

58/4 = X

14.5 = X

Therefore, every day Dajuan will paint 14.5 square feet of the wall.

Answer:

0.97725

Step-by-step explanation:

Given :

Population mean, μ = 4.2

Population standard deviation, σ = 1.8

Sample size, n = 36

Obtain the Zscore of x = 4.8

Zscore = (x - μ) ÷ (σ / √n)

Zscore = (4.8 - 4.2) ÷ (1.8 / √36)

Zscore = 0.6 ÷ 0.3

Z = 2

Hence,

P(Z ≤ 2)

Using the Z probability calculator :

P(Z ≤ 2) = 0.97725

Answer:

56  hardwood     80  pine bark

Step-by-step explanation:

H = hardwood    B= pine bark

B +H = 136

B = (136-H)

4.25 H + 3.75 (136-H) = 538

4.25H + 510 - 3.75H = 538

0.5 H = 28

1H = 56   (56 Hardwood)

136-56= 80  

56x 4.25 + 80 x 3.75 = 538

$238 + $300 = $538

Answer: 290 miles

Step-by-step explanation:

Given

Allison drove with a speed of 58 mph

Austin drove with a speed of 40 mph

If both start at the same time

suppose Allison takes t hours to reach the destination. So, the difference between the distance traveled in t hours is 90 miles

[tex]\Rightarrow 58t-40t=90\\\Rightarrow 18t=90\\\Rightarrow t=5\ hr[/tex]

Distance traveled by Allison is [tex]58\times 5=290\ miles[/tex]

Answer:

216 cubic inches

Jena's large jewelry box is 132 inches³ bigger than her small cube jewelry box.

What is a cube?

A cube is a three dimensional figure. All of it's sides are equal in length and all the planes of it are perfect square.

Given, length of the each side of Jena's small jewelry box = 2 inches.

Therefore, the volume of the small jewelry box is = 2³ inches³ = 8 inches³.

Again, length of the each side of Jena's small jewelry box are 7 inches, 5 inches, and 4 inches.

Therefore, the volume of the small jewelry box is = (7 × 5 × 4) inches³ = 140 inches³.

Hence, the difference = (140 - 8) inches³ = 132 inches³.

Step-by-step explanation:

Answer:

0.0283642

Step-by-step explanation:

Number of uppercase letters = 26

Number of lowercas = 26 alphabets = 10

Number of password characters = 10

Hence total number of passwords with exactly 10 characters (26 + 26 + 10) ^10 = 62^10 = 839299365868340224 passwords

Password with 10 strings, and having atleast one upper, lower and digit character :

26^1 * 26^1 * 10^1 * (26+26+10)^7 = 23806114737966080 (1 upper, lower and digit character, the remaining 7 could be any of them)

Probability = required outcome / Total possible outcomes

P(password with atleast 1 upper, lower and digit character) = 23806114737966080 / 839299365868340224

= 0.0283642

Answer:

Natalie is 13 years old, while Fred is 28 years old.

Step-by-step explanation:

Given that if you add Natalie’s age and Fred’s age, the result is 41, and if you add Fred’s age to 3 times Natalie’s age, the result is 67, to find how old Fred and Natalie are, the following calculation must be performed:

N + F = 41

3N + F = 67

(67 - 41) / 2 = N

26/2 = N

13 = N

13 x 3 + F = 67

39 + F = 67

F = 67 - 39

F = 28

28 + 13 = 41

Therefore, Natalie is 13 years old, while Fred is 28 years old.

The surface area of the figure will be equal to 1326 square meters.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called as the surface area.

Given that:-

The surface area will be calculated as:

SA = 2 { LW + LH + WH )

SA = 2 { ( 9 x 12) + (15 x 22 ) + (15 x 9 )}

SA = 1326 square meters.

Therefore the surface area of the figure will be equal to 1326 square meters.

[tex](x,y) = (3,24)[/tex]

Required

y when x = 4

[tex]y\ \alpha\ x^2[/tex]

Express as an equation

[tex]y = kx^2[/tex]

Substitute: [tex](x,y) = (3,24)[/tex]

[tex]24 = k*3^2[/tex]

[tex]24 = k*9[/tex]

To solve for y when x = 4, we have:

[tex]y = kx^2[/tex]

[tex]y = \frac{24}{9} * 4^2[/tex]

Answer:

C. 162.5 sq ft.

Step-by-step explanation:

Given the following data;

S.A of smaller cylinder, S1 = 65 ft²

Ratio = 2:5 = 2 + 5 = 7

Let the total surface area be x.

S1 = 2/7 * x = 65

S1 = 2x = 65 * 7

S1 = 2x = 455

x = 455/2

x = 227.5 ft²

To find the surface area of the larger cylinder;

S2 = 5/7 * 227.5

S2 = 1137.5/7

S2 = 162.5 ft²

3.75 is the correct answer

In order to figure out the half-life, you divide to sample by 2. In order to find how many times to divide it you divide 15 by 3 and get 5. Therefore, you divide 120 by 2, 5 times and get 3.75

The distance between two points is √29 unit.

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, also known as the Pythagorean theorem. The Pythagorean theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

We have the points (-2, 3) and (3, 1).

Using Distance formula

= √(1-3)² + (3 - (-2))²

= √ (-2)² + (5)²

= √ 4 + 25

= √29 unit

Thus, the distance between two points is √29 unit.
