Daniel works in a market. He has a large bag of potatoes that weighs 6514 pounds and he is going to sell them in smaller bags of 214 pounds each. If he uses up all the potatoes, how many smaller bags of potatoes will Daniel have filled? 29 32 3212 234916
Answer: 30 small bags
Step-by-step explanation:
From the question, we are informed that Daniel works in a market and that he has a large bag of potatoes that weighs 6514 pounds and he is going to sell them in smaller bags of 214 pounds each.
When he uses up all the potatoes, the number of smaller bags of potatoes that Daniel will have filled will be 6514 divided by 214. This will be:
= 6514/214
= 30.43
= 30 small bags
Solve for x and y, please help!
Answer:
x = 37, y = 9
Step-by-step explanation:
3x + 11 and x + 21 are same- side interior angles and are supplementary, thus
3x + 11 + x + 21 = 189 , that is
4x + 32 = 180 ( subtract 32 from both sides )
4x = 148 ( divide both sides by 4 )
x = 37
--------------------------------
3x + 11 = 3(37) + 11 = 111 + 11 = 122
14y - 4 and 3x + 11 are vertical angles and congruent, thus
14y - 4 = 122 ( add 4 to both sides )
14y = 126 ( divide both sides by 14 )
y = 9

Step-by-step explanation:
Tommy and Arnold are playing with water balloons. Arnold is standing by a bush that is 20 feet from where Tommy is standing. Tommy released a water balloon at 5 feet above the ground and hits Arnold’s chest- which is also 5 feet above the ground. The balloon reached a maximum height of 15 feet off the ground. using Tommy’s location as the starting point, help Tommy write an equation that describes the path of the water from the point of release to Arnold's chest. Using the equation y=a(x-h)^2+k
Answer:
The equation that describes the path of the water balloon is:
[tex]y =-\frac{1}{10}\cdot (x-10)^{2}+15[/tex]
Step-by-step explanation:
The motion of the water balloon is represented by quadratic functions. Tommy launches a water balloon from [tex]A(x,y) = (0\,ft, 5\,ft)[/tex] and hits Arnold at [tex]B(x,y) = (20\,ft, 5\,ft)[/tex]. Given the property of symmetry of quadratic function, water ballon reaches its maximum at [tex]C(x,y) = (10\,ft,15\,ft)[/tex], which corresponds to the vertex of the standard equation of the parabola, whose form is:
[tex]y = a\cdot (x-h)^{2}+k[/tex] (Eq. 1)
Where:
[tex]a[/tex] - Vertex parameter, measured in [tex]\frac{1}{ft}[/tex].
[tex]h[/tex], [tex]k[/tex] - Horizontal and vertical components of the vertex, measured in feet.
[tex]x[/tex], [tex]y[/tex] - Horizontal and vertical location of the ball, measured in feet.
If we know that [tex]x = 0\,ft[/tex], [tex]y = 5\,ft[/tex], [tex]h = 10\,ft[/tex] and [tex]k = 15\,ft[/tex], the vertex parameter is:
[tex]5\,ft = a\cdot (0\,ft-10\,ft)^{2}+15\,ft[/tex]
[tex]a = \frac{5\,ft-15\,ft}{(0\,ft-10\,ft)^{2}}[/tex]
[tex]a = - \frac{1}{10}\,\frac{1}{ft}[/tex]
The equation that describes the path of the water balloon is:
[tex]y =-\frac{1}{10}\cdot (x-10)^{2}+15[/tex]
12) Given A(9, 2), B(-1, y)
C.(-5, 16) and D(-8, 11),
find the value of y So
that AB is perpendicular CD
Answer:
y=8
Step-by-step explanation:
(y-2)/(-1-9)=(y-2)/-10 (11-16)/(-8-(-5))=-5/-3=5/3 Perpendicular slope is -3/5
(y-2)/10=-3/5 cross multiply 5(y-2)=3(10) 5y-10=30 add 10 to both sides
5y=40 divide both sides by 5 and y is equal to 8.
The value of y is 8 if AB is perpendicular CD after using the slope formula.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
A(9, 2), B(-1, y) C.(-5, 16) and D(-8, 11),
AB is the perpendicular CD
Using the slope formula to find the slope between A and B:
(y-2)/(-1-9)
= (y-2)/-10
(11-16)/(-8-(-5)) =
-5/(-3)
= 5/3
The perpendicular slope is -3/5
(y-2)/10=-3/5
5(y-2)=3(10)
5y-10=30
5y=40
y = 8
Thus, the value of y is 8 if AB is perpendicular CD after using the slope formula.

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00 per hour. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00 per hour.

of water needed to prepare 5 cups of rice?
Answer:
11.25
Step-by-step explanation:
Multiply 4.5 by the reciprocal of 2/5, which is 5/2. You will then get 11.25. Hope this helped :)
Total number of cups of water needed to prepare 5 cups of rice are 11.25.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
When rice is prepared, the amount of rice varies directly as the amount of water required.
And, 2 cups of rice requires 4.5 cups of water.
Now,
Since, 2 cups of rice requires 4.5 cups of water.
Hence, For 1 cup of rice, number of cups of water = 4.5 / 2
= 2.25
So, For 5 cups of rice, number of cups of water = 5 x 2.25
= 11.25
Thus, Total number of cups of water needed to prepare 5 cups of rice are 11.25.

which linear inequality is represented by the graph graph
Answer: choice A
Step-by-step explanation:
The linear inequality represented by the graph is y≥1/3x-1
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Let us find slope of line passing through points (0, -1) and (3, 0)
Slope = 0+1/3
=1/3
y intercept we have to find
0=1/3(3)+b
b=-1
So equation of line is y=1/3x-1
As the shading is away from origin, we use the greater than or equal to symbol.
y≥1/3x-1
Hence, the linear inequality represented by the graph is y≥1/3x-1

Answer:
1, 3, and 8
Step-by-step explanation:
You should know this because, 88 degrees and 2 are in a straight line which there means that 2 would be 92 degrees. So every length would be slightly shorter or longer than the other. As you can observe 1, 3, and 8 other than 6 are all the ones that are slightly shorter than their counterpart 2, 4, 5, and 7. Which means that 1, 3, and 8 all equal 88 degrees just like 6.

If the height of an equilateral triangle ABC is 5/ 3 cm. Let us write by calculating the area
of this triangle
• Height of the equilateral triangle = 5/3 cm .
To find :• The area of the triangle .
Solution:• First find side :
As we know that:
• Height = √3/2 (side)
=> 5/3= √3/2 (side)
=> side = 10/3√3 cm
• Area of equilateral triangle = √3/4 (side)².
=> Area = √3/4(10/3√3)²
=> Area = √3/4(100/27)
=> Area = 25√3/27
=> Area = 43.30/27
=> Area = 1.60 cm².
Hence, the area of equilateral triangle is 1.60cm²

Mercurys average distance fron the sun is 35,000,000 miles. It takes 3 minutes for light to travel from the sun to Mercury. Neptune with an average of 2.8 x 10 to the power or 9 miles from the sun. How many times farther from the sun is Neptune than Mercury? How ling does it take light to reach Neptune?
Answer:
Neptune is 80 times farther from the Sun than Mercury.
It takes 4 hours to reach the light from the Sun to Neptune.
Step-by-step explanation:
Given that the average distance between the Sun and Mercury,
[tex]d_1=35,000,000[/tex] miles [tex]=3.5\times 10^7[/tex] miles.
The time to reach the light from the sun to Mercury, [tex]t_1 = 3[/tex] minutes
Let v m/s be the speed of light.
So, [tex]v=\frac{d_1}{t_1}\cdots(i)[/tex] [as speed = distance/time]
Now, the average distance between the Sun and Neptune,
[tex]d_2=2.8\times 10^9[/tex] miles.
The ration of the average distance of Neptune and Mercury from Sun,
[tex]\frac{d_2}{d_1}=\frac{2.8\times 10^9}{3.5\times 10^7}[/tex]
[tex]\frac{d_2}{d_1}=80\cdots(ii)[/tex]
So, Neptune is 80 times farther from the Sun than Mercury.
The time to reach the light from the sun to Neptune,
[tex]=\frac{d_2}{v}[/tex] [as time=distance/speed]
[tex]=\frac{d_2}{d_1/t_1}[/tex] [using equation(i)]
[tex]=\frac {d_2}{d_1}\times t_1[/tex]
[tex]=80\times 3[/tex] [using equation(ii)]
=240 minutes
=4 hours [as 1 hour =60 minutes]
Hence, it takes 4 hours to reach the light from the Sun to Neptune.
Using the speed - distance relationship, we can deduce that Neptune is 80 times farther from the sun than Mercury and it will take 240 minutes for light from the sun to reach Neptune.
Given the Parameters :
Mercury's average distance from sun = 35000000 miles Time taken for light to travel to mercury = 3 minutes Neptune's average distance from sun = [tex] 2.8 \times 10^{9} [/tex]Number of times Neptune is father from the sun than Mercury :
(Neptune's distance) ÷ Mercury's distance [tex] \frac{2.8 \times 10^{9}}{35000000}= 80 [/tex]Hence, Neptune is 80 times farther from the sun than Mercury.
Time taken for light to reach Neptune :
Time taken to each mercury × 803 minutes × 80 = 240 Minutes
60 minutes = 1 hour
240 minutes = (240 ÷ 60) = 4 hours
Therefore, it would take 4 hours for light to reach Neptune.
