Answer:

23.88 cm squared

Step-by-step explanation:

3.6 x 5.9 = 21.24

1.1 x 4.8 x 1/2 = 2.64

21.24 + 2.64 = 23.88

3 squares are positioned to form a triangle. the small square is labeled 6 units, medium square is 8 units, and large square is

LuckyWell [14K]

The area of the square of the leg 6 is 36 square units.

The area of the square of the leg 8 is 64 square units.

The area of the square of the hypotenuse square is 100 square units.

The length of the hypotenuse is 10 units.

Formula Used

Area of square, A = $(a)^{2}$

Here, $a$ is the length of the side of the square.

Pythagoras Theorem is given as,

$h^{2} =p^{2} +b^{2}$

Here, $h, p, b$ are the hypotenuse, perpendicular, and the base of a right angle triangle respectively.

Area of the Square of the Leg 6

Length of the edge of the square = 6 units

Area of square = 6*6

= 36 square units

Area of the Square of the Leg 8

Length of the edge of the square = 8 units

Area of square = 8*8

= 64 square units

Area of the Hypotenuse Square and the Length of the Hypotenuse

Applying Pythagoras theorem,

$h^{2} = (8)^{2} +(6)^{2}$

$h^{2} = 64+36$

$h = \sqrt{100}$

$h = 10 units$

Therefore, the area of the hypotenuse square is 100 square units and the length of the hypotenuse comes out to be10 units.

Keesha Thompsons cousin is 8 years older than keesha. Write an expression for the age of keesha's cousin

Oliga [24]

Answer:

y = 8 + x or

Keesha.cousin.age = 8 + Keesha.age

Step-by-step explanation:

II. When Keesha.cousin is older than Keesha 8 years

Give y = 8 + x, when y is Keesha cousin.age, x is Keesha.age

y = 8 + x

II. Prove by given Keesha is 10 years old.

y = 8 + 10

y = 18 or Keesha cousin is 18 years old.

Hope that help :)

Linda and Imani are each traveling in a car to the beach. Linda’s travel is modeled by a table. Imanis travel it modeled by grap

tino4ka555 [31]

Answer:

Imani traveled faster because her distance surpassed Linda's distance after the fourth hour.

Step-by-step explanation:

1. Understand the slope:

Ok, so the slope basically tells us how fast Imani and Linda traveled, so if we solve for the slope we know how fast Imani and Linda traveled.

2. Find Linda's slope:

- Take any two points: (0,10) and (1, 65).

Slope = (y1 - y2)/(x1 - x2)

= (65-10)/(1-0)

= 55

Since the slope is 55, we know her speed is 55 miles per hour.

2. Find Imani's slope:

- Take any two points: (0,0) and (1, 60).

Slope = (y1 - y2)/(x1 - x2)

= (60-0)/(1-0)

= 60

Since the slope is 60, we know her speed is 60 miles per hour.

3. Compare: Since 60>55, we know Imani traveled faster. If we look at options, we can see there's only one answer which shows that Imani traveled faster, so that must be the answer.

A survey was done of 902 students. The mean of their results was 26 and the standard deviation was 4. How many students responde

Natali5045456 [20]

Answer:

11 students out of 902 responded above 35

Step-by-step explanation:

Using z-score we can find what percentage of student will be above 35. Using this percentage we can calculate how many students out of 902 scored above 35.

Mean = u = 26

Standard deviation = s = 4

Target Value = x = 35

Formula for the z score is:

$\frac{x-u}{s}$

Using the values in this formula, we get:

$\frac{35-26}{4} =2.25$

Using the z table we can find the percentage of values that would be 2.25 standard deviations above the mean in a normal distribution. Using the z-table we get this value to be 0.0122 or 1.22%

Thus 1.22% of the values will be above 35.

1.22% of 902 is 11 (rounded to nearest whole number)

Thus 11 students out of 902 responded above 35

Find the product of (1/5x^3)(10x)(1/5x^2)

Colt1911 [192]

Answer:

2/5x^6

Step-by-step explanation:

Times 1/5x^3 and 10x first

$\frac{1}{5} x {}^{3} \times \frac{10}{1} x = \frac{10}{5} x {}^{4}$

then Times the ans you got with 1/5x^2

$\frac{10}{5} x {}^{4} \times \frac{1}{5} x {}^{2} = \frac{10}{25} x {}^{6}$

After that you simplify Ur ans.

The numerator and the denominator are a multiple of 5 so divide both by 5.

You will get your ans

$\frac{10}{25} x {}^{6} = \frac{2}{5} x {}^{6}$
