Answer:

128cm²

Step-by-step explanation:

To find out how much material he needs, you need to find the surface area of the box. Each box has 6 sides, 2 of 3 different sides.

Surface area = 2(6 × 4) + 2(6 × 4) + 2(4 × 4)

                      = 128cm²

Answer:

904.32. cu.in

Step-by-step explanation:

diameter= 12 inches

radius= 13/2=6 inches

volume of sphere= 4/3 πr³ = 4/3 ×π × 6³ = 904.32 cu.in

The amount of air contain in kickball is,

⇒ V = 904.32 in³

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A kickball has the diameter of 12 inches.

Hence, We get;

⇒ Radius = 12/2

⇒ Radius = 6 inches

Since, We know that;

⇒ volume of sphere= 4/3 πr³

Hence, We get;

⇒ V = 4/3 ×π × 6³

⇒ V = 904.32 in³

Thus, The amount of air contain in kickball is,

⇒ V = 904.32 in³

Answer:

$525.13

Step-by-step explanation:

cost per month = total expenses /  months in a year

total expenses = fixed cost + variable cost

$2,125.10 + $4,176.43 = $6,301.53

Answer:

130

Step-by-step explanation:

The numbers after the decimal point are not up to 1, so they cannot be added up to the integer.

Answer:

130 to the nearest 100th

Step-by-step explanation:

100 - 129.392 = 29.392

30 - 29.392 = 0.608

1 - 0.608

= 0.392

0.392 - 0.002

= our negative thousandth

our negative 100th is 0.39 in 129.39

What is closer to 100 is for the other side  120 or 130 in 129.38

The answer is 130

For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98

Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.

For a population mean of 20.15 and a standard deviation of 3.7:

68% are within μ ± σ/√n, hence:

68% = 20.15 ± 3.7/√20 = (19.32, 20.98)

For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98

The characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have a circle equation in the inequality form:

(x – 6)² + (y – 12)² ≤ 196

The center of the circle is at (6, 12)

The radius of the circle is:

r² = 196

r = 14 units

After drawing a circle on the coordinate plane.

We will see, a circle with a solid boundary, center at (6, 12), and bounded solution set.

Thus, the characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.

Answer:

Step-by-step explanation:

Answer:

(B)-4

Step-by-step explanation:

Answer:

We know that a number is divisible by 3 if the sum of its digits is a multiple of 3.

if the sum is a multiple of 3 + 1  (like 3*n + 1) the remainder is 1

if the sum is a multiple of 3 + 2 (like 3*n + 2) the remainder is 2.

Then we need to find the sum of all the single digits in the number:

101102103104...149150

the sum of all the single digits is:

( 1 + 1) + (1 + 2) + (1 + 3) + ... + (1 + 4 + 9) + ( 1 + 5)

The method i used is:

(from 101 to 110)

first we sum the hundreds digit 10 times, and then we add the unit digits for each case, this is:

1*10 + (1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 + 1) = 10 + 46

From (111 to 119)

first we add the sum of the hundreds and tens digits 10 times, and then the units:

2*9 + ( 1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 )

now if we also add the number 120 (so we have the range 111 to 120)

the sum becomes:

2*9 + ( 1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 ) + 1 + 2

2*10 + (1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 + 1 ) = 20 + 46

You already can see the pattern here.

in the range from (121 to 130) we will have the sum equal to 30 + 46

in the range from (131 to 140) we will have the sum equal to 40 + 46

in the range from (141 to 150) we will have the sum equal to 50 + 46

Then the total sum is:

(10 + 20 + 30 + 40 + 50) + 5*46 = 380

We know that 380 is multiple of 3 (because 3 + 8+ 0 = 12)

Then the remainder is 0.

Step-by-step explanation:

2 : 5 ratio of catching catfish

X : 60

2/5 = X/60

6 x (2/5) = (X/60) x 60

60 x (2/5) = X

X = 60 x (2/5)

X = 24

The expression of x in terms of y for the case when  cos(xº) = sin(yº) is x° = cos^(-1)sin(y°)

Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.

In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slant side is called hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.

From that angle (suppose its measure is θ),

[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]

For this case, we have to express x in terms of y for [tex]\cos(x^\circ) = \sin(y^\circ)[/tex]

Since 0 < x < 90, and 0 < x < 90 so taking inverse cosine gives:

[tex]x^\circ= \cos^{-1}(\sin(y^\circ))[/tex]

Thus, the expression of x in terms of y for the case when  cos(xº) = sin(yº) is [tex]x^\circ= \cos^{-1}(\sin(y^\circ))[/tex]

If 2 6, which must be true about 2? 2 is complementary to 5.

Step-by-step explanation:

Let's begin noting that a triangle is isosceles if and only if two of its angles are congruent. We can thus find the angle <ABP, recalling that the sum of the interior angles of a triangle is equal to 180°.

[tex] \angle \: ABP = \frac{180 - 80}{2} = 50 \degree[/tex]

Finally, let point K be the intersection between segments BC and PQ, and let's note that the triangle PQB is a right isosceles triangle, since all the angles in a square are equal to 90°, and the two triangles APB and BQC are congruent.

Therefore, the angle BKQ is equal to 180-50-45=85°.

Of course angle BKP=180-85=95°.

Answer:

Since the division of the number of pedestrians by the number of years yields different values for each ratio, these ratios do not form a proportion.

Step-by-step explanation:

They will form a proportion if the division of the number of pedestrians by the number of years yields the same results.

20 pedestrians : 5 years

20/5 = 4 pedestrians per year.

7 pedestrians : 1 year

7/1 = 7 pedestrians per year.

Since the division of the number of pedestrians by the number of years yields different values for each ratio, these ratios do not form a proportion.
