Answer:

17

Step-by-step explanation:

Second square number is 9; 3×3

second cube number is 8; 2×2×2

9+8=17.

The area of the composite figure is 70 cm^2

The area of the figure = area of rectangle + area of a triangle

Area of rectangle = length * width
Area of rectangle = 10 * 5
Area of rectangle = 50 square centimeters

Area of triangle = 0.5(5)(8)

Area of triangle = 20 square cm

Area of the figure = 50 + 20
Area of the figure  = 70 square cm

Hence the area of the composite figure is 70 cm^2

A statement that best compares the average values of the number of fish caught at both lakes daily:

There is a significant difference between the sample means.

The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the sum of the total number of observations by the total number of observations.

The mean number of catfish caught daily at Lake Martin is 85,

with the number of catfish ranging from 75 to 140.

The mean number of catfish caught daily at Smith Lake is 104,

with the number of catfish ranging from 96 to 183.

The difference in all the sample means,

104 - 85 = 19.

Therefore, the difference is 19.

Note that:

Use the formula to find the area of each rhombus.

Correct option is C.

The weight of the 600 bricks is 1165.83 kg.

The total mass is the product of the volume of one brick, the number of bricks, and the density. For this problem, it is convenient to use dimensions in meters.

Given

A builder purchases 600 bricks for new residential construction.

The dimensions of each brick are 5. 1 cm by 10. 2 cm by 20. 3 cm.

The density of the brick is 1840 kg m3.

The density of the bricks is given by;

[tex]\rm =600\times (5.1 \ cm \times 10.2 \ cm \times 20.3 \ cm) = 633,603.6\ cm^3[/tex]

The weight, in kg to the hundredths, of 600 bricks is;

[tex]\rm 633,603.6 cm^3 \times \dfrac{ 1 m^3}{10^6 cm^3 }\times\dfrac{ 1840 kg}{m^3}= 1165.83[/tex]

Hence, the weight of the 600 bricks is 1165.83 kg.

Answer:

28.5714285714286 cm

Step-by-step explanation:

1 L = 1000 mL

1 L = 1000 cm^3

60 L = 60,000 cm^3 (multiply both sides by 60)

The cooler has volume of 60,000 cubic cm. Let V = 60000

Assuming the cooler is a rectangular prism (aka a block), then we can say

volume = length*width*height

V = L*W*H

60000 = 60*35*H

60000 = 2100H

2100H = 60000

H = 60000/2100

H = 28.5714285714286 which is approximate

And the surface area (SA) is

SA = 2*(LW + LH + WH)

SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)

SA = 9628.57142857143 which is also approximate

Step-by-step explanation:

The formed triangle is not right angled triangle. The area of circle is 19.64 square units.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The area of circle is -

A = πr² = π(d/2)²

A vector is represented by -

A = A[x] i + A[y] j + A[z] k

We have the following problem -

The corners of triangle PQR lie on a circle. PQ = 3i + 4j and PR = -8i + 6j.

|PQ| = 5 units

|PR| = 10

PR + RQ = PQ

RQ = PQ - PR

RQ = 11i - 2j

|RQ| = 11.18

It can be seen that it is not a right angled triangle.

Equation of the diameter of the circle -

y = 4/3x {Assuming it pass through origin}

Diameter length = 5

Radius length = 5/2

Area of circle = 22/7 x 5/2 x 5/2 = 19.64 square units.

Therefore, the formed triangle is not right angled triangle. The area of circle is 19.64 square units.

Answer:

y=mx+b

Points are in (x,y) form so 5 is x and -6 is y

We know m = -1/7 (because m is slope)

So we can plug these values in to find b.

So:

-6 = 5(-1/7) + b

-6 = (-5/7) + b

-6 + 5/7 = b

b = -37/7

Answer:

There are total 120 ways to arrange the letters of word "COUNT".

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.

[tex]nP_{r} =\frac{n!}{(n-r)!}[/tex]

Where,

P is the number of arrangements.

r is the of objects selected.

n is the total numbers of object.

According to the question.

We have a word "COUNT".

Total number of letters in word "COUNT" is 5.

⇒ Total number of objects, n = 5

Since, we have to form different words by using 5 letters of count.

⇒ Total number of objects we have to select, r = 5

Therefore, the total number of ways to arrange the letters of "COUNT" is given by

[tex]5P_{5}=\frac{5!}{(5-5)!}[/tex]

⇒[tex]5P_{5} =\frac{5!}{0!}[/tex]

⇒[tex]5P_{5} =\frac{5!}{1}[/tex]      (because,0! = 1)
