Answer:
160% of 35 is 56.
Step-by-step explanation:
[tex]\frac{56}{y} :\frac{160}{100}[/tex]
y · 160 = 56 · 100
160y = 5600
160y ÷ 160 = 5600 ÷ 160

Find the area of the shaded region in the drawing round to the nearest tenth show all work
Answer:
The area of the shaded region is:
488 ft^2.Step-by-step explanation:
First, we're gonna find the area of the whole rectangle and next we can subtract the area of the triangles in the corners, we use the next formula:
Area of a rectangle = width * heigthAnd we replace the measurements in the picture (32 ft and 16 ft):
Area of a rectangle = 16 ft * 32 ftArea of a rectangle = 512 ft^2Now, we must calculate the area of a triangle, this can be made by this formula:
Area of a triangle = (base * height) / 2We can replace the values we have in the picture (4 ft and 6 ft), then:
Area of a triangle = (4 ft * 6 ft) / 2Area of a triangle = (24 ft^2)/ 2Area of a triangle = 12 ft^2As you can see in the picture, we have to subtract two triangles with the same measurements, by this reason, we multiply the area of the triangle by two and we'll obtain the area we must subtract:
Area to subtract = (12 ft^2) * 2Area to subtract = 24 ft^2At last, we take the area of the whole rectangle and subtract the area of the triangles:
Area of the shaded region = 512 ft^2 - 24 ft^2Area of the shaded region = 488 ft^2The area of the shaded region is 488 ft^2.

The table below represents which equation ?
Answer:
D
Step-by-step explanation:
Find the slope by picking two ordered pairs in the table and using the slope formula( y2-y1/x2-x1) to get the slope. The smallest numbers are easiest to work with. (-1,1), (0,-2)
-2-1/0-(-1) = 3/0+1 = -3/1 = m=-3
Use one of the points you used and plug in the x and y values of the ordered pair into the equation with the slope to find your b( y-intercept). (0,-2)
-2= -3(0) +b
-2= 0+b
b=-2
The final equation will only have your slope and b( y-intercept). That should be your answer. Hope this helps!

What is the solution to the equation √8x = √4+2x?
Answer and Step-by-step explanation:
The first step in solving for x is to square both sides.
8x = 4 + 2x
Now, subtract 2x from both sides.
6x = 4
Now, divide each side by 6.
x = [tex]\frac{4}{6} = \frac{2}{3}[/tex]
x = [tex]\frac{2}3}[/tex] is the answer.

If the radius of a cylinder is 3 centimeters and the height of the cylinder is 4 centimeters, then the area of the lateral surface is 75.36 square centimeters. True False
Answer:
True
Step-by-step explanation:
The Answer is 75.36 cm
2 x (pi)3.14 = 6.28
6.28 x (r)3 = 18.84
18.84 x (h)4 = 75.36
The statement, "If the radius of a cylinder is 3 centimeters and the height of the cylinder is 4 centimeters, then the area of the lateral surface is 75.36 square centimeters." is true.
What is cylinder?"A cylinder is a three-dimensional geometrical structure which consists of two circular bases connected with a curved surface."
Formula to calculate the area of the lateral surface of a cylinder:For a cylinder with radius r and height h,
the curved / lateral surface area is,
A = 2 × π × r × h
Given: r = 3 cm, h = 4 cm
Using the formula for area of lateral surface of a cylinder:
⇒ A = 2 × π × 3 × 4
⇒ A = 24 × π
⇒ A = 24 × 3.14
⇒ A = 75.36 sq.cm.
Therefore, given statement is true.

Which equation in rectangular form describes the parametric equations x=2-3 cos t and y=1+4 sin t?
Answer:
The parametric equations represents an ellipse by the rectangular equation [tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex].
Step-by-step explanation:
We proceed to use the following trigonometric identity to derive an expression in rectangular form:
[tex]\cos^{2} t + \sin^{2} t = 1[/tex] (1)
Where:
[tex]\cos t = \frac{2-x}{3}[/tex] and [tex]\sin t = \frac{y-1}{4}[/tex]

[tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex] (2)
The parametric equations represents an ellipse by the rectangular equation [tex]\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1[/tex].
A sixth grade class recorded the number of letters in each students first name. The results are shown in the dot plot. Which is the best representation of the center of this data set?
Answer:
the center of the data set is 7 so probably 7
7 is the best representation of the center of given data set.
The correct answer is an option (C).
What is center of data?"It is the middle of a distribution.""Mostly, The measures of the center of the data are the mean and the median."What is mean?"It is the average of the given numbers."
What is median?"I is the middle value of a sorted list of numbers."
For given question,
We have been given a dot plot of the number of letters in each students first name.
From the given dot plot,
We have data as 3, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6,6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10, 10, 11, 11, 11
From above data,
the total number of students in the class are n = 30
We write 3, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6,6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10, 10, 11, 11, 11 as 3, (4 × 2), (5 × 4), (6 × 7), (7 × 7), (8 × 3), 9, (10 × 2), (11 × 3)
So, the mean of the above data would be,
[tex]\Rightarrow \bar{X}=\frac{3+ (4\times 2)+(5\times 4)+(6\times 7)+(7\times 7)+(8\times 3)+9+(10\times 2)+(11\times 3)}{30}\\\\\Rightarrow \bar{X}=\frac{208}{30}\\\\\Rightarrow \bar{X}=6.93\\\\\Rightarrow \bar{X}\approx 7[/tex]
From above data we can observe that there are two numbers in middle of the data 6 and 7.
So, the median would be,
[tex]\Rightarrow M=\frac{6+7}{2}\\\\\Rightarrow M=6.5\\\\\Rightarrow M\approx 7[/tex]
Therefore, 7 is the best representation of the center of given data set.

find the difference between 0.1 kg and 75g
Answer:
25 g
Step-by-step explanation:
0.1 kg can be written as 100 grams
& 75 g
while 1 kg is 1000 grams
so difference:-
(100- 75 ) grams
= 25 g
The difference between 0.1 kg and 75 g is 25 grams. To find the difference between 0.1 kg and 75g, you need to make sure both quantities have the same unit.
Since 1 kg is equal to 1000 g, you can convert 0.1 kg to grams:
0.1 kg = 0.1 * 1000 g = 100 g
Now, the two quantities are in the same unit:
0.1 kg - 75 g = 100 g - 75 g = 25 g
So, the difference between 0.1 kg and 75 g is 25 grams.

Eight eagle stamps and two raccoon stamps cost $2.80. Three eagle stamps and four raccoon stamps cost $2.35. Find the cost of each kind of stamp
Show work please
Answer:
Cost of each eagle stamp = $0.25
Cost of each racoon stamp = $0.4
Step-by-step explanation:
Given:
Cost of 8 eagle stamp and 2 racoon stamp = $2.80
Cost of 3 eagle stamp and 4 racoon stamp = $2.35
Find:
Cost of each stamp
Computation:
Assume;
Cost of each eagle stamp = e
Cost of each racoon stamp = r
So,
8e + 2r = 2.80........... Eq 1
3e + 4r = 2.35 ........... Eq 2
Eq 1 x 2
16e + 4r = 5.6 .........Eq3
Eq 3 - Eq 2
13e = 3.25
e = 0.25
Cost of each eagle stamp = $0.25
8e + 2r = 2.80
8(0.25) + 2r = 2.80
2 + 2r = 2.80
r = 0.4
Cost of each racoon stamp = $0.4

If there is a $50 profit on the large cabinets and a $30 profit on the small cabinets.
What number of large and small cabinets maximizes the objective function?
P = 50x + 30y
a) o large and 10 small
b) 8 large and small
c) 4 large and small
d) 4 large and 5 small
Answer: B
Step-by-step explanation: I hope I am good at math if not sorry
The combination of 8 large cabinets and 8 small cabinets maximizes the objective function, resulting in a value of 640. Option b is correct.
To maximize the objective function P = 50x + 30y, where x represents the number of large cabinets and y represents the number of small cabinets.
Need to determine the combination of x and y that results in the highest value for P.
For 0 large and 10 small:
P = 50(0) + 30(10)
= 0 + 300
= 300
For 8 large and 8 small:
P = 50(8) + 30(8)
= 400 + 240
= 640
For 4 large and 4 small:
P = 50(4) + 30(4)
= 200 + 120
= 320
For 4 large and 5 small:
P = 50(4) + 30(5)
= 200 + 150
= 350
Based on these calculations, 8 large cabinets and 8 small cabinets maximizes the objective function, resulting in a value of 640.
