Answer:

20

Step-by-step explanation:

To calculate percent from a fraction, you can multiply the value of the fraction by 100. 20/100*100 is 20, so there is a 20% chance.

The required blank space could be filled with 20% as, If the chance of getting a disease is 20 out of 100, this would be the same as having a 20% chance.

Given that,
If the chance of getting a disease is 20 out of 100, this would be the same as having a ______ % chance, to determine what value can be put.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
According to the question,
percentage of get affected by disease = 20 / 100 = 0.20 or 20%

Thus, the required blank space could be filled with 20% as, If the chance of getting a disease is 20 out of 100, this would be the same as having a 20% chance.

Answer:

Common denominators of 9 and 2 are 18,36

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

let the two numbers be X and Y

let larger number = Y

from the first statement

Y - X = 9 equation (1)

from the second statement

Y = 1+ 2X equation (2)

substitute equation (2) into (1)

1+2X-X = 9

1+X= 9

X = 9-1 = 8

X= 8

put X = 8 into equation (2)

Y= 1+2X

Y= 1+2(8)

Y= 1+16 = 17

larger number = 17.

Answer:

Each son received from their mother $287.50

Step-by-step explanation:

3(x - 275) = x - 250

2x = 825 - 250

x = 287.50

$287.50 - $275 = $12.50

Check the answer:

After spending the older son has $12.50  

$287.50 - $250 = $37.50

After spending the younger son has $37.50

$37.50 ÷ $12.50 = 3 times

Step-by-step explanation:

The solution is, D. They grow heavy and fall to the ground.,  is part of the process in the formation of hail pellets.

Graupel is also called snow pellets or soft hail, as the graupel particles are particularly fragile and generally disintegrate when handled. Sleet are small ice particles that form from the freezing of liquid water drops, such as raindrops.

here we have,

Hail is a form of precipitation when droplets of water freeze together in the cold upper reaches of the thunderstorms.  

Thee chunks of that range from 5 to 15 cm can be round and jagged. Hail fall on the ground in a solid form they are often associated with tornadoes and certain parts of the world receive more hail than other parts do.

These frozen droplets of water when fall from the clouds get uplifted by wind and that adds another layer to them. The freezing occurs below the zero degrees at an altitude of 11,000 feet.

Mostly found in North America Nebraska, colorado and Wyoming states. and African regions in winter and South America in summer.

Answer:

9

Step-by-step explanation:

Given equation:

[tex]5 = \dfrac{x}{3} + 2[/tex]

To determine the solution (x) of the equation, we need to isolate it.  To do this, we can subtract 2 both sides of the equation.

[tex]\implies 5 - 2 = \dfrac{x}{3} + 2 - 2[/tex]

[tex]\implies 3 = \dfrac{x}{3}[/tex]

To further isolate "x", we can use cross multiplication.

[tex]\implies 3 \times 3 = x[/tex]

Finally, simplify the expression on the left-hand-side to obtain the value of x.

[tex]\implies \boxed{9 = x}[/tex]

Answer:

The formula for semicircle area is [tex]\frac{1}{2} \pi r^2[/tex]

Very similar to the formula for finding area of a circle, but since a semicircle is half of a circle, the formula will be revolving around halves.

5,870,000,000,000 miles.

The distance light travels in 100 years.

The distance of the light travels in 100 years is:

5,870,000,000,000 × 100 miles.

= 587,000,000,000,000 miles

= 587 × 10^12 miles.

answer= option d

[tex]1 \: year = 5870000000000 \: miles[/tex]

The distance which light can travel in 100 years.

to find the distance which light can travel in 100 years, multiply the distance which light can travel in 1 year (5,870,000,000,000 miles) by 100.

[tex] = 5870000000000 \times 100[/tex]

[tex] = 587000000000000 \: miles[/tex]

[tex] = 587 \times {10}^{12} [/tex]

Answer:

Step-by-step explanation:

Isolate the term of r, from one side of the equation.

First, multiply by 2 from both sides.

2*3/2r=2(-1)

Solve.

3r=-2

Then, you divide by 3 from both sides.

3r/3=-2/3

Solve.

Divide the numbers from left to right.

r=-2/3

-2/3=-0.66

[tex]\Longrightarrow: \boxed{\sf{r=-\dfrac{2}{3}}}[/tex]

I hope this helps! Let me know if you have any questions.

Answer:

[tex]{ \qquad{ {{ \tt{ - \frac{2}{3} }}}}} \\ \\[/tex]

Given equation,

[tex] \\ { \longrightarrow \qquad{ {{ \tt{ \frac{3}{2} \: r = -1 }}}}} \\ \\[/tex]

Multiplying both sides by [tex] \sf \dfrac{1}{3}[/tex] we get :

[tex] \\ { \longrightarrow \qquad{ {{ \tt{ \frac{1}{3} \times \frac{3}{2}r = \frac{1}{3} \times -1 }}}}} \\ \\[/tex]

[tex] { \longrightarrow \qquad{ {{ \tt{ \frac{1}{ \cancel3} \times \frac{ \cancel3}{2}r = - \frac{ 1}{ 3} }}}}} \\ \\[/tex]

[tex] { \longrightarrow \qquad{ {{ \tt{ \frac{1}{2}r = - \frac{1}{3} }}}}} \\ \\[/tex]

Now, Multiplying both sides by 2 we get :

[tex] \\ { \longrightarrow \qquad{ {{ \tt{ 2 \times \frac{1}{2}r = 2 \times - \frac{1}{3} }}}}} \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ {{ \tt{ \cancel2 \times \frac{1}{ \cancel2}r = - \frac{2}{3} }}}}} \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ {{ \tt{ {1}r = - \frac{2}{3} }}}}} \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \frak {{ \pmb{ r = - \frac{2}{3} }}}}} \\ \\[/tex]

In this case, the equation is in vertex form. To graph the parabola, we need to determine the y-intercept, x-intercept(s), and the vertex.

Vertex form: y = a(x + h)² - k

Assume "y" as 0.

[tex]\implies 0 = 3(x + 2)^{2} - 1[/tex]

[tex]\implies 1 = 3(x + 2)^{2}[/tex]

Take square root both sides and simplify:

[tex]\implies\sqrt{1} = \sqrt{3(x + 2)^{2}}[/tex]

[tex]\implies1 = \sqrt{3 \times (x + 2) \times (x + 2)}[/tex]

[tex]\implies1 = (x + 2) \times \sqrt{3[/tex]

Divide √3 both sides:

[tex]\implies \±\huge\text{(}\dfrac{1 }{\sqrt{3}} \huge\text{)} = (x + 2)[/tex]    

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{1} }{\sqrt{3}} \huge\text{)} = (x + 2)[/tex]    

Multiply √3 to the numerator and the denominator:

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{1} \times \sqrt{3} }{\sqrt{3\times \sqrt{3}}} \huge\text{)} = (x + 2)[/tex]

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{3} }{3}} \huge\text{)} = (x + 2)[/tex]

[tex]\implies \±\huge\text{(}\dfrac{\sqrt{3} }{3}} \huge\text{)} - 2 =x[/tex]

[tex]\implies x = \underline{-2.6...} \ \text{and} \ \underline{-1.4...} \ \ \ \ (\text{Nearest tenth})[/tex]

Assume "x" as 0.

y-intercept = 11 ⇒ (0, 11)

Since the first cooeficient is positive (+3), the direction of the parabola will be upwards.

Axis of symmetry line: x-coordinate of vertex

Axis of symmetry line: x = -2

Plot the following on the graph:

Refer to graph attached.

Answer:

Vertex form of a quadratic equation:

[tex]y=a(x-h)^2+k\quad \textsf{where }(h,k)\:\textsf{is the vertex}[/tex]

Given equation:  [tex]y=3(x+2)^2-1[/tex]

Therefore, the vertex is (-2, -1)

The x-intercepts are when [tex]y=0[/tex]:

[tex]\implies 3(x+2)^2-1=0[/tex]

[tex]\implies 3(x+2)^2=1[/tex]

[tex]\implies (x+2)^2=\dfrac13[/tex]

[tex]\implies x+2=\pm\sqrt{\dfrac13}[/tex]

[tex]\implies x+2=\pm\dfrac{\sqrt{3}}{3}[/tex]

[tex]\implies x=-2\pm\dfrac{\sqrt{3}}{3}[/tex]

[tex]\implies x=\dfrac{-6\pm\sqrt{3}}{3}[/tex]

Therefore, the x-intercepts are at -2.6 and -1.4 (nearest tenth)

The y-intercept is when [tex]x=0[/tex]:

[tex]\implies 3(0+2)^2-1=11[/tex]

So the y-intercept is at (0, 11)

The axis of symmetry is the x-value of the vertex.  Therefore, the parabola is symmetrical about x = -2

**You don't need to plot the axis of symmetry - I have added it so that it is easier to draw the curve**

Step-by-step explanation:

Area of a triangle = 1/2*a*h

1/2*9*3 = 13.5

Area of a parallelogram = a*h

12*13 = 156

156-13.5 = 142.5

Answer:

Below.

Step-by-step explanation:

Mean = (61+59+60+50+54+56+61+63)/8

= 464/8

= 58 degrees

Deviations:

61 - 58 = 3

59-58 = 1

60-58 = 2

50-58 = -8 = 8   (absolute value)

54-58= -4 = 4

56-58 = -2 = 2

61-58 = 3

63-58 = 6

MAD = (3+1+2+8+4+2+3+6) / 8

= 3.625

= 3.6 to the nearest tenth.

Answer:

C) 24

Step-by-step explanation:

Alternate interior angles are equal

so angle 1 equals angle 6

3x+10=x+58

subtract 10 from both sides

3x=x+48

then subtract x from both sides

2x=48

dived each side by two

x=24

[tex]because~of~the~angles\\BC = 3k\\AB = 4k[/tex]

⇒ (AB)² + (BC)² = (AC)²

in which because of AB and BC's values, goes into...

⇒ (4k)² + (3k)² = (AC)²

because of that ↑ you get the values of what is below.

⇒ (AC)² = 16 k² + 9 k²

add 16k and 9k for the result below.

⇒ (AC)² = 25 k²

⇒ AC = ±5k

the sin is the side opposite to the angle, so find the hypotenuse and opposite angle.

[tex]Side~opposite~to~angletheta\\= BC(3k)\\\\Hypotenuse\\= AC(5k)[/tex]

That said →  [tex]sintheta = \frac{BC}{AC} = \frac{3k}{5k} = \frac{3}{5}[/tex]
