1 2/3 - 2/3

How to get it

5/3 simplifies into 1 and 2/3 and since you are doing addition and subtraction with x it cancels them out making it 1 and 2/3 minus 2/3, which would equal, 1, hope this helps!

Answer:

1 2/3 - 2/3

Step-by-step explanation:

You get this answer by canceling out the x's since they are the both the same with both the numbers: 5/3 and 2/3. So then you convert 5/3 into 1 2/3 and finish the rest of the equation which would end up being 1 2/3 - 2/3.

Final answer:

To find the height of the 7th bounce of a bouncy ball, where each bounce is 64% of the height of the previous one, use the geometric sequence formula. For the first bounce's height of 5.5 feet and a common ratio of 0.64, calculate the 6th power of 0.64, then multiply by 5.5 and round to the nearest tenth.

Explanation:

The student is asking about finding the height of the seventh bounce of a bouncy ball, which follows a geometric sequence in which each term is 64% of the previous one. To find the height of the 7th bounce, we will use the formula for the nth term of a geometric sequence, which is an = a1 × r(n-1), where a1 is the first term, r is the common ratio, and n is the term number.

The first term a1 is the height of the first bounce, which is 5.5 feet, and the common ratio r is 0.64 (since 64% is 0.64 in decimal form). Using this information, the height of the 7th bounce is calculated as follows:

Calculate the 6th power of the common ratio: 0.646

Multiply this value by the height of the first bounce: 5.5 × 0.646

Round the result to the nearest tenth

Calculating the exact value and rounding to the nearest tenth gives us the height of the seventh bounce.

Answer:

The solution is x = 6 and y =1

Explanation :

In the substitution method we solve a system of equation by substituting the value of one variable from an equation to the another equation,

Given system of equations,

x-y = 5  ⇒ y = x - 5.......(1)

2x+y = 13.......(2)

Substitute the value of y from equation (1) to equation (2),

2x+x-5=13

3x-5=13

3x=18

x = 6

Again from equation (1),

y = 6 - 5 = 1

Like a lot of math, it's about pattern matching.

9680 yards. Miles biked a total of 9680 yards.

The key to solve this problem is coverting the Mixed Fraction to Improper Fraction, and make the conversion from miles to yards.

Convert the Mixed Fraction 5 1/2 to an Improper Fraction:

- Multiply the whole number 5 by the denominator

5 x 2 = 10

- Add the result to the numerator

1 + 10 = 11

- Write the Improper Fraction with the same denominator of the Mixed Fraction, and the numerator with the result above

5  1/2 miles ---------->  11/2 miles

To convert miles to yard with mile = 1760 yards:

11/2 * 1760 yards = 19360 yards/2 = 9680 yards

Final answer:

Miles biked for a total of 5 1/2 miles. By converting miles to yards using the fact that there are 1,760 yards in one mile, Miles biked a total of 9,680 yards.

Explanation:

The student has asked how many yards Miles biked if he rode a total of 5 1/2 miles. To find the answer, we need to convert miles to yards. Since there are 1,760 yards in a mile, we can multiply the number of miles by this conversion factor.

First, let's represent 5 1/2 miles as an improper fraction: 5 1/2 = 11/2 miles. Next, we multiply 11/2 by 1,760:

11/2 miles
= 11/2
* 1760 yards/mile
= 11*880 yards
= 9,680 yards.

Therefore, Miles biked a total of 9,680 yards.

Answer:

x=-1

Step-by-step explanation:

General equation of line is y=mx+n where m is slope. So, if we use point (-4, 8) and slope in equation we have 8= 2/3.(-4)+n

Then we have n=8+8/3, that is n=32/3

Therefore equation of our line is y=2/3.x + 32/3

For the point (x,10) in equation 10=2/3.x + 32/3

Then we have 2/3.x = - 2/3 then x= -1

Answer:

x = - 1

Step-by-step explanation:

Using the slope formula to find the slope m

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (x , 10) and (x₂, y₂ ) = (- 4, 8)

m = [tex]\frac{8-10}{-4-x}[/tex] = [tex]\frac{2}{3}[/tex], that is

[tex]\frac{-2}{-4-x}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )

2(- 4 - x) = - 6 ( divide both sides by 2 )

- 4 - x = - 3 ( add 4 to both sides )

- x = 1 ( multiply both sides by - 1 )

x = - 1

Answer:

1/2 is the answer (actually, it's ±1/2)

Step-by-step explanation:

The identity you need here is for a half angle of tangent.  That identity is as follows:

[tex]tan(\frac{\theta }{2})=[/tex]±[tex]\sqrt{\frac{1-cos\theta }{1+cos\theta } }[/tex]

If we need the cos of that angle, we need to find the missing hypotenuse.  Applying Pythagorean's Theorem to that right triangle, we get that the hypotenuse is 5.  The cos of the angle is 3/5.  Filling in the formula, using only the principle root since you have not allowed for the negative in the choices you gave:

[tex]tan(\frac{\theta }{2})=\sqrt{\frac{1-\frac{3}{5} }{1+\frac{3}{5} } }[/tex]

Turning each one of those 1's into 5/5 we combine the fractions to simplify to:

[tex]tan(\frac{\theta }{2})=\sqrt{\frac{\frac{2}{5} }{\frac{8}{5} } }[/tex]

Bringing up the lower fraction and flipping to multiply gives us:

[tex]tan(\frac{\theta }{2})=\sqrt{\frac{2}{5}*\frac{5}{8}  }[/tex]

Canceling out the 5's and reducing the remaining fraction gives us

[tex]tan(\frac{\theta }{2})=\sqrt{\frac{1}{4} }[/tex]

and since the square root of 4 is 2, we end with a solution of 1/2

Answer:

The real zero is between 1 and 2.

Step-by-step explanation:

The given function is:

[tex]f(x)=x^3-2[/tex]

To find the zeros of this function, we set f(x)=0.

[tex]\implies x^3-2=0[/tex]

Add 2 to both sides to obtain:

[tex]\implies x^3=2[/tex]

Take the cube root of both sides

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

[tex]\implies x=1.26[/tex]

Therefore the real zero is between 1 and 2.

Answer:

x = 30t cos 20 or  x = 28.19t.

y = 30t sin 20 - 4.9t^2 + 2 or y =  -4.9t^2 + 10.26t + 2.

Step-by-step explanation:

The horizontal component of the velocity = 30 cos 20  m/s so the distance at time t seconds = 30t cos 20.

The vertical component  is obtained from the equation of motion

s = ut - 1/2* 9.8t^2 + 2

u = 30 sin 20

Vertical component  =  30t sin 20 - 4.9t^2 + 2.

Answer:

x(t) = 30t cos 20 or we can get x = 28.19t. y = 30t sin 20 – 4.9t^2 +2 or y= -4.9t^2 + 10.26t +2

Step-by-step explanation:

The path the rock took can be represented by the following equation x(t) = v0 * cos(θ) * t y (t) = v0 * sin (θ) * t – 0.5 * g * t^2 + h. v0 is the initial velocity (30 m/s), θ is the angle of launch (20 degrees), g is the acceleration due to gravity (9.8 m/s^2) , h is the initial height (2m ) , and t is time. When we switch the values, we get x(t) = 30t cos 20 or we can get x = 28.19t. y = 30t sin 20 – 4.9t^2 +2 or y= -4.9t^2 + 10.26t +2

Now calculate like so:

PLEASE DO MARK ME AS BRAINLIEST UWU

Answer:

Your answer for this question is 255.

Step-by-step explanation:

To solve this problem, we must remember how to use PEMDAS.  This tells us that we must simplify what is in parentheses first, exponents next, then multiplication and division, and finally addition and subtraction.  In this case, this means that we must first perform the operations inside of the parentheses before the multiplication of the two groups of parentheses.

If we simplify within both groups of parentheses, we get:

(2+2+3+10) * (8+9+-9+7)

= (17) * (15)

We get the above simplification by performing the addition of all of the constants in the first group of parentheses and performing the addition and subtraction in the second group (notice that the +9 and -9 cancel each other out).

Now, we must simply multiply together our final two values to obtain our final answer.

17 * 15 = 255

Therefore, your answer is 255.

Answer:

60°

Step-by-step explanation:

Here we are given that the number of convertibles cars. Total number of cars owned by the dealers is 90. We have to draw the pie graph for above ratio. The pie chart is a circular statistical graph , where the different portion in form of sectors on the circle showing the amount of different entities.

The angle covered by an entity is in the same proportion as its number is in ration to the total number of all the entities.

Hence

[tex]\frac{15}{90}=\frac{\theta}{360}\\\\\theta=\frac{15*360}{90}\\\theta=\frac{15*4}{1}\\\theta=60\\[/tex]

Hence we will represent 60 degrees in order to represent 15 cars in our chart.

To represent convertibles on the pie graph, calculate the proportion of convertibles sold to the total number of cars sold (15/90) and multiply by the total degrees in a circle (360). Convertibles should be represented by a 60-degree slice on the pie graph.

The question is asking how to calculate the degree measure for the convertibles slice in a pie chart based on the total sales in a month. We know that a pie chart represents 100% of a data set, with the entire chart being a 360-degree circle. To find the degree measure for the convertibles, we would perform a proportion calculation based on the number of convertibles sold (15) out of the total number of cars sold (90). The calculation is as follows:

Proportion of convertibles to total sales = (Number of convertibles sold / Total cars sold) = 15 / 90

Now, multiply this proportion by the total degrees in a circle to get the degree measure for convertibles:

Degree measure for convertibles = Proportion of convertibles imes Total degrees in a circle = (15 / 90) * 360 = 1/6 * 360 = 60 degrees

Therefore, the convertibles should be represented by a 60-degree slice on the Pie Graph.
