The volume of a hemisphere with a radius of 44.9 m is approximately 189582.2 cubic meters, rounded to the nearest tenth.

To calculate the volume of a hemisphere, you can use the formula

V = (2/3)πr^3

where V is the volume, π is pi (approximately 3.14), and r is the radius. In this case, r = 44.9 m.

So, (2/3)π(44.9)^3 = 189582.234 cubic meters.

This is the exact volume, but since the question asked for the volume rounded to the nearest tenth, the final answer would be 189582.234 cubic meters. It's worth mentioning that a hemisphere is half of a sphere, thus, the volume of a full sphere with a radius of 44.9 m would be double of this value.

Kathy can make 10 headbands from 3/4 of a yard of fabrics.

An equation is an expression composed of variables and numbers linked together by mathematical operations.

The unit rate is the ratio of two different units. The unit rate must always have a denominator equal to 1.

Kathy has 3/4 of a yard of fabric. She needs 3/10 of a yard to make a 4 headband.

Hence:

3/10 yards = 4 head band

For 3/4 yard:

number of headbands = 3/4 yard * 4 headband per 3/10 yard = 3/4 * 4 / (3/10) = 3/4 * 4 * 10/3 = 10

Since, Four distinct fair coins are tossed. if it is known that at least one of the coins shows a head . The probability that all coins show heads is 3/4.

Probability:

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes for an event. In an experiment with 'n' outcomes, the number of favorable outcomes can be denoted by x. The formula for calculating the probability of an event is:

  Probability (Event) = Favorable Outcome / Total Outcome = x/n

The probability of an event can be calculated using the probability formula by simply dividing the number of favorable outcomes by the total number of possible outcomes. The value of the probability that an event will occur can range from 0 to 1. This is because the preferred number of outcomes can never exceed the total number of outcomes. Also, the resulting favorable number can never be negative.

Given that:

Four District fair coins are tossed.

So, possible outcomes are

    HH,HT,TH,TT

We know that:

Probability= total possible outcomes / favorable outcomes

Now,

​Favorable outcomes = HH,HT,TH

Step-by-step explanation:

The formula for the sum of a geometric sequence is: S = a(1 - r^n) / (1 - r)

In this case, our a = -8, r = -3, and n = 10.

S = -8(1 - (-3)^10) / (1 - (-3))

Answer:

x² + (y + 5)² = 61

Step-by-step explanation:

the equation of a circle in standard form is

(x - a)² + (y - b)² = r²

where (a, b ) are the coordinates of the centre and r is the radius

here (a, b ) = (0, - 5 ) and r has to be found

(x - 0)² + (y - (- 5) )² = r² , that is

x² + (y + 5)² = r²

the radius is the distance from the centre to a point on the circle.

using the distance formula to find r

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, - 5 ) and (x₂, y₂ ) = (- [tex]\sqrt{60}[/tex] , - 6 )

r = [tex]\sqrt{(-\sqrt{60}-0)^2+(-6-(-5))^2 }[/tex]

 = [tex]\sqrt{(-\sqrt{60})^2+(-1)^2 }[/tex]

  = [tex]\sqrt{60+1}[/tex]

  = [tex]\sqrt{61}[/tex]

then r² = ( [tex]\sqrt{61}[/tex] )² = 61

the equation of the circle is then

x² + (y + 5)² = 61

The correct option is A, the linear equation has no solutions.

Here we want to see how many solutions do the equation below has:

(1/4)*(8 - 24x) = 12 - 6x

Now let's try to solve that linear equation, we can start by simplifying the left side:

(1/4)*(8 - 24x) = 12 - 6x

8/4 - 24x/4 = 12 - 6x

2 - 6x = 12 - 6x

Now we can add 6x in both sides, so we will get:

2 - 6x + 6x = 12 - 6x + 6x

2 = 12

That is a false equation, thus, the equation has no solutions.

Answer:

0.75 is less than 1, so the portrait will be smaller than the actual head.

Step-by-step explanation:

The art teacher has said that the portrait will be 0.75 times as tall as the actual head.

0.75 is less than 1, so the portrait will be smaller than the actual head.

A ratio of 0.75 means that the portrait will be 3/4 the size of the actual head. So, if the actual head is 8 inches tall, the portrait will be 6 inches tall (8*0.75 = 6). Therefore, the portrait will be smaller than the actual head.

Have a lovely day :)

Answer:

There's no m so I'm assuming you meant b.

The angle of b is 121

Step-by-step explanation:

The shape here is a heptagon. The formula for calculating the sum of interior angles is ( n − 2 ) × 180. *n represents the number of sides.

(7-2) × 180               There are 7 sides so plug that in.

(5) × 180 = 900       This means the shape's interior angles add up to 900.

Now, all we have to do is add up all the sides known and set it equal to 900.

c + d + e + f + g + a = 900

148 + 90 + 142 + 130 + 139 + 130 + b = 900

779 + b = 900              

now subtract 779 from both sides to isolate b.

The ratios are 80 : 2/3, 10 : 1/12 and 90 : 3/4 for the equivalent ratio 20 : 1/6.

By dividing both the antecedent and consequent values by a similar fraction, equivalent ratios can be reduced to the same value. In other words, two ratios are deemed equivalent if the bigger one in value can be expressed as a multiple of the other.

Therefore, we only need to multiply the two amounts by the same number to obtain the equivalent ratio of another ratio. Equivalent ratios and equivalent fractions both have similar ideas. Examples of equivalent ratios include 1:2 and 4:8, 3:5 and 12:20, 9:4 and 18:8, etc.

After finding the answers, write (a,b) to indicate the interval of x-values that make the inequality true. The interval notation for -3 and 5 is (-3,5).

Generally, Before you can create an interval notation for a quadratic inequality, you must first solve for the values of x that are compatible with the inequality being satisfied. In most cases, this will require factoring the quadratic expression and fixing it so that it equals zero.

After that, the sign of inequality will be used to decide which solutions are appropriate. After you have determined the solutions, you may indicate the range of x-values that cause the inequality to hold using the notation (a,b), where a and b stand for the solutions, respectively.
