If you roll two fair six-sided dice, what is the probability that the sum is 444 or higher?

Answer:

Find a line which also has 3/4 as the slope or 3x - 4y in standard form.

Step-by-step explanation:

If the line is 3x - 4y = 1 then the line which is parallel will have the same coefficients of x and y. Parallel lines never cross and to ensure this have the same slope. The slope is a ratio which can be solved for in an equation using the coefficients of x and y. Here the slope is:

3x - 4y = 1

-4y = -3x + 1

y = 3/4x - 1/4.

[tex]\boxed{A=43.54cm^2}[/tex]

To find this area we will use the law of cosine and the Heron's formula. First of all, let't find the unknown side using the law of cosine:

[tex]x^2=12^2+8^2-2(12)(8)cos(65^{\circ}) \\ \\ x^2=144+64-192(0.42) \\ \\ x^2=208-80.64 \\ \\ x^2=127.36 \\ \\ x=\sqrt{127.36} \\ \\ \therefore \boxed{x=11.28cm}[/tex]

Heron's formula (also called hero's formula) is used to find the area of a triangle using the triangle's side lengths and the semiperimeter. A polygon's semiperimeter s is half its perimeter. So the area of a triangle can be found by:

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex] being [tex]a,\:b\:and\:c[/tex] the corresponding sides of the triangle.

So the semiperimeter is:

[tex]s=\frac{12+8+11.28}{2} \\ \\ s=15.64cm[/tex]

So the area is:

[tex]A=\sqrt{15.64(15.64-12)(15.64-8)(15.64-11.28)} \\ \\ \therefore \boxed{A=43.54cm^2}[/tex]

Answer:

Step-by-step explanation:

If you are asking how many hours she spent on the batting lessons, we can use an equation to solve this type of problem.

Lets represent the hours she spent batting in august with h.

$35h+15=$155

Since each hour costs 35 dollars, its reasonable that $35 times the number of hours she spent practicing would be the correct way to represent that.

Now, lets solve.

Subtract 15 on both sides.

$35h=$140

Divide both sides by 35 to isolate h.

h=4

She spent four hours on batting lessons that month.

Hope this helps!

The number of hours will be 4 hours.

Let the number of hours used be represented by h.

Based on the question, the equation that will be used in solving the question will be:

15 + (35 × h) = 155

15 + 35h = 155

Collect like terms.

35h = 155 - 15

35h = 140

Divide both side by 35

35h/35 = 140/35.

h = 4.

The number of hours is 4 hours.

Answer:

14

Step-by-step explanation:

Angles are usually  given in degrees or in radians.

A circle is 360 degrees.

To convert degrees to radians, multiply the known degree by π/180.

Example 45 degrees = 45 x π/180 = 0.7854 radians.

To convert radians to degrees, multiply the known radian by 180/π.

5 radian = 5 x 180/π = 286.48 degrees.

The correlation between the measurements is written below.

An angle is a combination of two rays with a common endpoint.

The endpoint is called as the vertex of the angle,the rays are called the sides.

The various units in which angle is measure are Degree, radians and revolutions

A revolution is the measure of an angle formed when the initial side rotates all the way around its vertex until it reaches its initial position

One radian (1 rad) is the measure of the central angle (an angle whose vertex is the center of a circle) that intercepts an arc whose length is equal to the radius of the circle.

A degree is equal to 360 revolutions.

The correlation between the measurements can be written as

[tex]\rm 1 \;radian =(\dfrac{180}{\pi })^o = \dfrac{1}{2\pi } revolution[/tex]

For example 30° = π/6 radian = 1/12 revolutions

Answer:

Option c. Reflection across the x-axis and vertical stretch by a factor of 7

Step-by-step explanation:

If the graph of the function [tex]y = cf(x)[/tex] represents the transformations made to the graph of [tex]y = f(x)[/tex] then, by definition:

If [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor a.

If [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor a.

If [tex]c <0[/tex] then the graph is reflected on the x axis.

In this problem we have the function [tex]y = -7secx[/tex] and our paretn function is [tex]y = secx[/tex]

What sentence below

Answer:

128 ft / second.

Step-by-step explanation:

It's acceleration is due to gravity and is 32 ft s^-2.

To find the velocity when it hits the ground we use the equation of motion

v^2 = u^2 + 2gs    where  u = initial velocity, g = acceleration , s = distance.

v^2 = 0^2 + 2 * 32 * 256

v^2 = 16384

v =  128 ft s^-1.

The rock will strike the ground with a velocity of 128 ft/s and will experience an acceleration of 32 ft/s^2.

First, we need to calculate the time it takes for the rock to fall to the ground. We can use the equation h = (1/2)gt^2, where h is the height of the building (256 ft) and g is the acceleration due to gravity (32 ft/s^2). Solving for t, we find t = sqrt(2h/g) = sqrt(2(256)/32) = 4 seconds.

Next, we can calculate the velocity of the rock just before it hits the ground. We can use the equation v = gt, where g is the acceleration due to gravity and t is the time it takes to fall (4 seconds). Plugging in the values, we find v = (32 ft/s^2)(4s) = 128 ft/s.

Lastly, the acceleration of the rock is equal to the acceleration due to gravity, which is 32 ft/s^2.

No, it is not the same because in option 1, the interest is calculated based on two different principal amounts and then added together. The principal amounts will be different every year because of the varying interest rates. Since one of the interest rates in option 1 is 7%, the principal will grow at a faster rate because the interest rate is applied to a greater and greater principal amount over time. In option 2, the interest is being calculated only on one principal  

Answer:

Step-by-step explanation:

No, they are not always the same - the only time that they will be the same is after the first year:

$4000*1.05 + $4000*1.07 = $8480 = $8000*1.06

From there on, they will diverge. For example after the second year:

$4000*1.05^2 + $4000*1.07^2 = $8989.6

$8000*1.06^2 = $8988.8

After the third year:

$4000*1.05^3 + $4000*1.07^3 = $9530.672

$8000*1.06^3 = $9528.128

After the nth year:

The first option gives $4000*(1.05^n + 1.07^n)

The second option gives $8000*(1.06^n)

= $4000*(2)*(1.06^n)

= $4000*(1.06^n + 1.06^n)

Because 1.07^n - 1.06^n > 1.06^n - 1.05^n for n>1, the first option will be a better investment.

Buckets of Soil : Buckets of Peat Moss = 5 : 4

Since Mr Carver needs to use 324 buckets in all,

He needs to use 324 * 5/9 = 180 buckets of Soil and 324 * 4/9 = 144 buckets of Peat Moss.

Mr. Carver will use 180 buckets of soil and 144 buckets of peat moss to fill the planting bed, based on the given ratio of 5 buckets of soil to 4 buckets of peat moss.

The problem at hand revolves around ratios and proportions where Mr. Carver is using a mix of soil and peat moss in a specific ratio to fill a planting bed. Given the ratio of 5 buckets of soil to 4 buckets of peat moss, we need to find the total number of buckets for each that will sum up to 324 buckets. First, we'll find the total number of parts in the ratio by adding 5 (for soil) and 4 (for peat moss), which gives us 9 parts. Since we have the total amount of 324 buckets, we can find the value of one part by dividing 324 by 9, which gives us 36.

Once we have the value of one part, we multiply it by the number of parts for soil and peat moss to find their respective quantities:

Therefore, Mr. Carver will use 180 buckets of soil and 144 buckets of peat moss to fill the planting bed.

Tom walks at a rate of 4/3 miles per hour, which means he will walk 1.333 miles in one hour at this rate.

To find out how many miles Tom will walk in 1 hour, we need to determine the distance he covers in 1/4 of an hour and then calculate how much he would walk in 1 hour at that rate.

Given Tom walks 1/3 of a mile in 1/4 of an hour, first find how much he walks in 1 hour:
1/3 mile ÷ (1/4 hour) = 1/3 mile * 4/1 hour = 4/3 miles in 1 hour

Therefore, Tom will walk 4/3 miles in 1 hour at that pace.

Tom would walk 4/3 miles or 1 and 1/3 miles in 1 hour given that he walks 1/3 of a mile in 1/4 of an hour based on the unit rate calculation.

The question deals with finding out how many miles Tom will walk in 1 hour if he walks 1/3 of a mile in 1/4 of an hour. To calculate this, we use the concept of a unit rate, which is finding how much of something is done in one unit of something else, in this case, miles per hour. Since Tom walks 1/3 of a mile in 1/4 of an hour, we can set up a proportion to find out how many miles he would walk in 1 full hour.

The proportion is: (1/3) miles / (1/4) hour = x miles / 1 hour. To solve for x, we multiply both sides of the equation by 1 hour so x would equal (1/3) miles \/ (1/4) hour. To simplify the right side, we invert the fraction in the denominator and multiply:
x = (1/3) miles \/ (1/4). When we multiply by the reciprocal of 1/4, which is 4, we get x = (1/3) \/ 1 \/ 4 = 4/3 miles.

Therefore, at this rate, Tom would walk 4/3 miles or 1 and 1/3 miles in 1 hour.

If the graph of any function is an unbroken curve, then the function is continuous. Let's study the function at the the point [/tex]x=5[/tex]:

At this point the function has the following value:

[tex]f(5)=-\frac{3}{4}[/tex], so the function in fact exists here, but let's find the limit here using:

[tex]f(x)=\frac{x^2-7x+10}{x^2-14x+45}[/tex]

So:

[tex]\underset{x\rightarrow5}{lim}\frac{x^2-7x+10}{x^2-14x+45}[/tex]

By factoring out this function we have:

[tex]\underset{x\rightarrow5}{lim}\frac{(x-2)(x-5)}{(x-5)(x-9)} \\ \\ \therefore \underset{x\rightarrow5}{lim}\frac{(x-2)}{(x-9)} \\ \\ \therefore \frac{(5-2)}{(5-9)}=-\frac{3}{4}[/tex]

Since [tex]\underset{x\rightarrow5}{lim}f(x)=f(5)[/tex] then the function is continuous here.

Let's come back to our function:

[tex]f(x)=\frac{x^2-7x+10}{x^2-14x+45}[/tex]

If we factor out this function we get:

[tex]f(x)=\frac{(x-2)}{(x-9)}[/tex]

Notice that at x = 9 the denominator becomes 0 implying that at this x-value there is a vertical asymptote. The graph of this function is shown below and you can see that at x = 9 the function is not continous

Step-by-step explanation:

We know that the sum of the measures of angles on one side of the parallelogram is 180°.

We have the equation:

(6x - 12) + (132 - x) = 180

6x - 12 + 132 - x = 180               combine like terms

(6x - x) + (-12 + 132) = 180

5x + 120 = 180              subtract 120 from both sides

5x = 60          divide both sides by 5

x = 12

Opposite angles in the parallelogram are congruent.

Therefore:

6y + 18 = 6x - 12

Put the value of x to the equation and solve it for y:

6y + 18 = 6(12) - 12

6y + 18 = 72 - 12

6y + 18 = 60           subtract 18 from both sides

6y = 42          divide both sides by 6

y = 7
