Answer:

y=-65/9

Step-by-step explanation:

12(5+2y)=4y-(5-9y)

60+24y=4y-5+9y

60+24y=13y-5

60+24y-13y=-5

60+9y=-5

9y=-5-60

9y=-65

y=-65/9

The value of y that satisfies the equation is y = -65/11.

The equation is given as follows:

12(5+2y) = 4y - (5 - 9y)

To find the value of y that satisfies the equation, we can solve for y by simplifying the equation.

Given equation:

12(5 + 2y) = 4y - (5 - 9y)

First, let's simplify both sides of the equation:

60 + 24y = 4y - 5 + 9y

Next, let's combine like terms:

24y - 4y - 9y = -5 - 60

Simplifying further:

11y = -65

Finally, divide both sides of the equation by 11 to solve for y:

y = -65/11

Therefore, the value of y that satisfies the equation is y = -65/11.

To find the volume of a cube with a given surface area, we can use the formula for surface area and rearrange it to find the side length. Once we have the side length, we can calculate the volume of the cube.

To find the volume of a cube, we need to determine the length of one side. Since a cube has 6 equal sides, we can calculate the length of each side using the formula for surface area: surface area =  6 * side length * side length. Let's rearrange the formula to find the side length: side length = sqrt(surface area / 6). Once we have the side length, we can calculate the volume using the formula: volume = side length * side length * side length. Plugging in the given surface area of 6534 square feet, we find that the volume of the cube is approximately 2314 cubic feet.

Answer:

One-sixth x + 47

1 and two-thirds x + 35 minus 1 and one-half x + 12

1 and one-third x + 35 minus 1 and one-half x minus 12

Step-by-step explanation:

The original expression in this problem is

[tex]5(\frac{1}{3}x+7)-3(\frac{1}{2}x-4)[/tex]

We start by applying the distributive property and multiplying each factor outside the brackets by each factor inside:

[tex]5\cdot \frac{1}{3}x+5\cdot 7 -3\cdot \frac{1}{2}x+3\cdot 4[/tex]

So we get:

[tex]\frac{5}{3}x+35-\frac{3}{2}x+12[/tex]

Now we can rewrite this using mixed fractions:

[tex]1\frac{2}{3}x+35-1\frac{1}{2}x+12[/tex] (1)

Which can be also written as

[tex]1\frac{2}{3}x+35-(1\frac{1}{2}x-12)[/tex] (2)

And finally, by solving it, we find

[tex]\frac{1}{6}x+47[/tex] (3)

So the three correct options are

One-sixth x + 47

1 and two-thirds x + 35 minus 1 and one-half x + 12

1 and one-third x + 35 minus 1 and one-half x minus 12

The number of rows she had been completed before Elena started working is 12 rows.

Suppose the considered function whose graph is to be made is

f=f(x) f(x)

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values

f=f(x) f(x)

are plotted on the vertical axis.

They are together plotted on the point

f(x)) (x,y) = (x, f(x))

This is why we usually write the functions as:

f(x) y = f(x)

We are given that;

The points= (14,19), (20,22), (30,27)

Now,

To find the number of rows completed before Elena started working, we need to find the equation of the line that passes through the given points on the graph.

Using the slope formula, we can find that the slope of the line is (27-22)/(30-20) = 0.5.

Using the point-slope form of a line, we can write the equation as y - 22 = 0.5(x - 20).

Simplifying the equation, we get y = 0.5x + 12.

To find the y-intercept, which is the number of rows completed before Elena started working, we plug in x = 0 and get y = 12.

Therefore, by the given graph the answer will be 12 rows.

Answer:

2.62 seconds

Step-by-step explanation:

Let

t ----> the time in seconds

h(t) ----> he height of the ball, in feet

we have

[tex]h(t)=-16t^2+40t+5[/tex]

we know that

When the ball hits the ground, the height is equal to zero

so

[tex]-16t^2+40t+5=0[/tex]

The formula to solve a quadratic equation of the form

[tex]at^{2} +bt+c=0[/tex]

is equal to

[tex]t=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]-16t^2+40t+5=0[/tex]

so

[tex]a=-16\\b=40\\c=5[/tex]

substitute in the formula

[tex]t=\frac{-40\pm\sqrt{40^{2}-4(-16)(5)}} {2(-16)}[/tex]

[tex]t=\frac{-40\pm\sqrt{1,920}} {-32}[/tex]

[tex]t=\frac{-40+\sqrt{1,920}} {-32}=-0.12\ sec[/tex]

[tex]t=\frac{-40-\sqrt{1,920}} {-32}=2.62\ sec[/tex]

therefore

The solution  is t=2.62 seconds

96 m

2 m/sec²

Step-by-step explanation:

Step 1:

In a velocity and time graph , the area which is under the plotted line represents the distance traveled

In the given graph , the plotted line from t=0 to t=4 ( for the first 4 secs) is a   triangle with base = 4 and height = 8

Area of this triangle is (1/2) * b * h = (1/2)* 4*8 = 16 m

Step 2 :

The plotted line from t = 4 to t = 14 is a rectangle with length equal to 10 and breadth equal to 8

Hence its area = length * breadth = 10 * 8 = 80 m

Step 3 :

Total  distance traveled is 80 + 16 = 96 m

Step 4 :

In the velocity time graph , slope denotes the acceleration at any given time. Since we want the acceleration for the first 4 secs, we need to find  slope of  line in from t = 0 to t= 4

when t = 0, v =0 and t= 4, v = 8

Slope = 8-0/4-0 =2 m/sec²

Answer:

2(x + 3)(4x + 1)

Step-by-step explanation:

The area (A) of the rectangle is calculated as

A = length × width

length = 2(x + 3)

width = 2x + x + 1 + x = 4x + 1

Thus

A = 2(x + 3)(4x + 1)

Answer:

1/7

Step-by-step explanation:

Heads: 1/2

Accomplished: 14 letters

Accomplished: 4 vowels

P(vowel) = 4/14 = 2/7

P(H and vowel) = 1/2 * 2/7 = 1/7

Final answer:

The probability of tossing a head and then selecting a vowel from the word 'accomplishment' is 3/28 or approximately 0.107.

Explanation:

The question asks us to find the probability of getting a head on a coin toss and then picking a vowel from the word 'accomplishment'. First, we determine each probability separately. The probability of getting a head when tossing a fair coin is 1/2, as there are two outcomes (head or tail), and getting a head is one of them.

The word 'accomplishment' has 14 letters, of which 3 are vowels (a, o, i). Therefore, the probability of picking a vowel at random from 'accomplishment' is 3/14. To find the combined probability of both events happening in sequence (tossing a head then picking a vowel), we multiply the probabilities of the individual events: (1/2) * (3/14) = 3/28 or approximately 0.107.

Answer:

(5/2, -9/4)

Step-by-step explanation:

To find the values of x and y requires solving equations, refining the solution through iterative methods like the extended Newton-Raphson technique, and validating results with approximation checks.

In answering this mathematical question, we are attempting to find specific values for the variables x and y. To solve for these variables, we employ various mathematical methods such as the Newton-Raphson technique for refinement.

Keeping the referenced data in consideration, the equations provided reveal that we manipulate these equations to gradually reach a more accurate result. For instance, taking the quadratic equation y²-0.30068y +0.022500 = 0 and using the quadratic formula y = 0.30068 ± √(0.30068)² – (4)(1)(0.022500) allows us to find the value for y, and an iterative process enhances the precision of x and y.

Remember to always retain a few extra significant figures to minimize rounding errors in the computational process. Additionally, entering our data into a calculator or a computer program will help in writing the linear equation, which needs to be rounded to an appropriate number of decimal places for accuracy. Examples mentioned illustrate evaluating the coordinates of a point, substituting values into equations, and analyzing the relation between variables through a graphical approach.

To validate our results, we compare the approximation to the actual value to ensure that our error margin is acceptable, especially when dealing with extrapolations from implicit differentiation in calculus contexts.

The deep of the sand will be 3.5 feet

Step-by-step explanation:

step 1

Find out the area of the court plus a 10-foot boundary around the  court for safety

[tex]A=(30+10+10)(60+10+10)\\A=(50)(80)\\A=4,000\ ft^2[/tex]

step 2

Find the deep of the sand

we know that

The volume of the sand is equal to

[tex]V=Ah[/tex]

where

A is the area of the base

h is the height or deep of the sand

substitute the given values

[tex]14,000=(4,000)h[/tex]

Solve for h

[tex]h=14,000/4,000=3.5\ ft[/tex]

Jerry's indoor beach volleyball court, including a 10-foot boundary, would have an area of 4,000 square feet, and with 14,000 cubic feet of sand, it would result in the sand being 3.5 feet deep.

Since Jerry wants to build an indoor beach volleyball court with a 10-foot boundary around it and has ordered 14,000 cubic feet of sand, we need to calculate the volume of the sand to determine how deep it will be when spread evenly over the entire area, including the boundary. The dimensions of the volleyball court are 30 feet by 60 feet, and adding a 10-foot boundary around it increases each dimension by 20 feet (10 feet on each side), resulting in a total area dimension of 50 feet by 80 feet.

To calculate the depth of the sand, we first calculate the area of the court including the boundary: Area = length × width = 50 feet × 80 feet = 4,000 square feet. Next, we divide the total amount of sand by the area to find the depth: Depth = volume / area = 14,000 cubic feet / 4,000 square feet = 3.5 feet deep. Therefore, if Jerry uses all the sand, it will be 3.5 feet deep.
