In the circle graph what is the measure of the center so angle for carrots and potatoes combined?
Round your answer to the nearest whole number.
Answer:
68°
Step-by-step explanation:
To find the angles represented by the percentages , you should have in mind that the total sum of all angles in the pie-chart equals 360°
The percentages given are;
Other=34%Potatoes=8%Carrot=11%Green Beans=12%Corn=15%Broccoli=20%The total percentages for the items
[tex]=34+8+11+12+15+20=100[/tex]
To get the angles represented by each percentage
Angle x=item/100 ×360°
Where x is the angle of an item in the circle graph
Calculating angles for carrot and potatoes
[tex]C=\frac{11}{100} *360=39.6\\\\\\P=\frac{8}{100} *360=28.8\\\\\\P+C=39.6+28.8=68.4[/tex]
The combined angle will be 68.4°

Which classification best represents a triangle with side lengths 10 in., 12 in., and 15 in.?
Answer:
It's an acute angled triangle.
Step-by-step explanation:
15^2 = 225
12^2 = 144
10^2 = 100
Adding:
10^2 + 12^2 = 244.
So as 15^2 < 12^2 + 10^2 this is an acute angled triangle.
The triangle with given sides of 10 inch , 12 inch and 15 inch is an acute angled triangle.
The length of three sides of a triangle are given
Length of first side = 10 inch
Length of second side = 12 inch
Length of third side = 15 inch
here we can observe that the third side is the longest side for the given triangle
Let us check whether the given triangle satisfies the Pythagorean theorem
For a right angled Pythagorean theorem is given by equation (1)
[tex]\rm H^2 = P^2 + B^2 .........(1)\\where \\H = Hypotenuse\\P = Perpendicular\\B = Base\\[/tex]
From the given data we can conclude that
[tex]\rm 15 ^2 = 225 \\10^2 = 100\\12^2 = 144 \\15^2 \neq 10^2 +12^2 \\\\Since\; 225\neq 244[/tex]
The given triangle does not satisfies the Pythagorean theorem and hence it is not a right angled triangle
also [tex]225< 244[/tex]
So we can conclude that it is an acute angled triangle.

Question worth 10 points
Use the following statements to write a compound statement for the conjunction or disjunction. Then find its truth value.
p: An isosceles triangle has two congruent sides.
q: A right angle measures 90°.
r: Four points are always coplanar.
s: A decagon has 12 sides.
r ∧ (q ∨ s)
Select one:
A. Four points are always coplanar, or a right angle measures 90° and a decagon has 12 sides; false.
B. Four points are always coplanar, and a right angle measures 90° or a decagon has 12 sides; true.
C. Four points are always coplanar, or a right angle measures 90° and a decagon has 12 sides; true.
D. Four points are always coplanar, and a right angle measures 90° or a decagon has 12 sides; false.
Answer:
Options b and D
Step-by-step explanation:
It's a question of Boolean's algebra
We will find the truth values of each statement p, q, r, and s first.
p : An isosceles triangle has two congruent sides.
Means truth value is True
q ; A right angle measures 90°
Truth value of this statement will be True
r : Four Points are always coplanar.
Truth value of this statement will be False.
s : A decagon has 12 sides
Truth value of the statement will be False.
Now we come to the options.
a. Four points are always coplanar and a right angle measures 90°.
Here "and" means conjunction and truth value of conjuncion of two statements will be true if only both the statements are true.
r q r ∧ q
T T T
But the truth value is given as false so not the correct option.
b. Four points are always coplanar and a right angle measures 90°.
As we have discussed in option a. truth value of the conjunction is True so this option will be the correct option.
c. Four points are always coplanar or a right angle measures 90°
OR means it's a disjunction and truth value of disjunction is false only when both the statements are False.
r q r ∨ q
T T T
But the truth value is given as False, so this option is not correct.
d. Four points are always coplanar or a right angle measure 90°
As discussed in option c. Truth value will be True. so this option will be the correct option.
Options b and d are the correct options.
cuboid of length 24cm and volume 768cm^3 the width and hight are not equal.give a pair of possible values for their length.
Answer:
Possible values of dimensions are (24,16,2) or (24,8,4)
Step-by-step explanation:
We are given the volume of the Cuboid and length . We are required to find the possible values of width and height from this information.
Let us say that the width is x and height is y
Length = 24
Volume of a cuboid = length * width * height
Volume = 768
768=24*x*y
[tex]xy=\frac{768}{24}\\xy=32\\[/tex]
xy=32
Now the possible factors of 32
32=1*32 ( Which shall not be taken into consideration as length is already given as 24 and width or height can not be more length)
32=2*16
32=4*8
Hence the possible values width are 8, 16 and that of height 4 and 2
Hence the possible values of dimensions are (24,16,2) or (24,8,4)

Select the solution(s) of the original equation.
x = 1 + sqrt 2
x = 2 + sqrt 2
x = 3 + sqrt 2
x = 1 - sqrt 2
x = 2 - sqrt 2
x = 3 - sqrt 2
For this case we have to:
Let[tex]u = x + 1[/tex]
So:
[tex]u ^ 2-4u + 2 = 0[/tex]
We have the solution will be given by:
[tex]u = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]
Where:
[tex]a = 1\\b = -4\\c = 2[/tex]
Substituting:
[tex]u = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (1) (2)}} {2 (1)}\\u = \frac {4 \pm \sqrt {16-8}} {2}\\u = \frac {4 \pm \sqrt {8}} {2}\\u = \frac {4 \pm \sqrt {2 ^ 2 * 2}} {2}\\u = \frac {4 \pm2 \sqrt {2}} {2}[/tex]
The solutions are:
[tex]u_ {1} = \frac {4 + 2 \sqrt {2}} {2} = 2 + \sqrt {2}\\u_ {2} = \frac {4-2 \sqrt {2}} {2} = 2- \sqrt {2}[/tex]
Returning the change:

a) The possibility space is completed with the potential outcomes of spinning both spinner A and spinner B.
b) The probability of getting a negative score is 2/9.
c) The probability of scoring more than 3 is also 2/9.
a) **Possibility Space:**
```
Spinner A
2 4 6
Spinner B 3 1 -1 -3
6 4 0 -2
9 7 3 1
```
In the possibility space, each cell represents the outcome of spinning both spinner A and spinner B. The score is obtained by subtracting the number on spinner A from the number on spinner B.
b) **Probability of Getting a Negative Score:**
To calculate the probability of getting a negative score, count the number of occurrences where the result is negative and divide it by the total number of possible outcomes. In this case, there are two instances (-1 and -2) where the score is negative. The total number of outcomes is 9.
Probability of negative score = Number of negative outcomes / Total number of outcomes
Probability of negative score = 2 / 9
c) **Probability of Scoring More Than 3:**
To find the probability of scoring more than 3, count the number of occurrences where the result is greater than 3 and divide it by the total number of possible outcomes. In this case, there are two instances (4 and 7) where the score is more than 3.
Probability of scoring more than 3 = Number of outcomes > 3 / Total number of outcomes
Probability of scoring more than 3 = 2 / 9

a shaded region above a solid boundary line
a shaded region below a solid boundary line
a shaded region above a dashed boundary line
a shaded region below a dashed boundary line
Answer: D is correct dotted and shaded below
Step-by-step explanation:
It’s a dotted line because the symbol is < or >
Everything below the line will be shaded because it’s y<, if it were y> then everything would be shaded above
Answer:
A shaded region below a dashed boundary line
Step-by-step explanation:
Conveniently it has been established, that in inequalities graph dashed lines indicate that all the points ∈ line expressed by y< -1/2x+5 part of the inequality are not included. So we represent by shaded regions below dashed lines.
If this inequality was then expressed by y<= -1/2x +5 then a solid line would then represent.

If (-4,32) and (7,-45) are two anchor points on the trend line, then find the equation of the line.
the equation of the trend line is y = -7x + 4.
To find the equation of the trend line using two points, we need to determine the slope (m) and the y-intercept (b) of the line. The slope is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the given points.
For the points (-4, 32) and (7, -45), the slope would be:
m = (-45 - 32) / (7 - (-4))
m = (-77) / (11)
m = -7
Now, we use the slope and one point to find the y-intercept using the point-slope form of the equation of a line, y - y1 = m(x - x1), and then we convert it to the slope-intercept form, y = mx + b.
Using point (-4, 32), the equation becomes:
32 = -7(-4) + b
32 = 28 + b
b = 32 - 28
b = 4
So, the equation of the trend line is y = -7x + 4.

the graph shows vectors a and b the resulting vector for b - a is blank, blank >, and the resulting vector for 2a -b is < blank, blank >.
Answer:
The resulting vector b - a is <-5 , 7>
The resulting vector 2a - b is <8 , -9>
Step-by-step explanation:
* Use the graph to solve the problem
- The vector a is <3 , -2>
- The vector b is <-2 , 5>
* We can add and subtract the vectors
∵ a = <3 , -2>
∵ b = <-2 , 5>
- To find b - a subtract a from b
∴ b - a = <-2 , 5> - <3 , -2> = <(-2 - 3) , (5 - -2)> = <(-5) , (7)>
∴ The resulting vector b - a is <-5 , 7>
* 2a means multiply vector a by 2
∵ a = <3 , -2>
∴ 2a = <(2 × 3) , (2 × -2) = <6 , -4>
* Now lets find the resulting vector 2a - b
- Subtract b from 2a
∵ 2a = <6 , -4>
∵ b = <-2 , 5>
∴ 2a - b = <6 , -4> - <-2 , 5> = <(6 - -2) , (-4 - 5> = <(8) , (-9)> = <8 , -9>
∴ The resulting vector 2a - b is <8 , -9>

Step-by-step explanation:
[tex]\text{The formula of a volume of a sphere:}\\\\V=\dfrac{4}{3}\pi R^3\\\\R-radius\\\\\text{A diameter}\ D=2R\Rightarrow R=\dfrac{D}{2}.\\\\\text{Therefore}\\\\V=\dfrac{4}{3}\pi\left(\dfrac{D}{2}\right)^3=\dfrac{4}{3}\pi\left(\dfrac{D^3}{8}\right)=\dfrac{D^3}{6}\pi[/tex]
[tex]\text{We have the dimater}\ D=10in.\ \text{Substitute:}\\\\V=\dfrac{10^3}{6}\pi=\dfrac{1000}{6}\pi=\dfrac{500\pi}{3}\ in^3[/tex]
For this case we have that by definition, the volume of a sphere is given by:
[tex]V = \frac {4} {3} \pi * r ^ 3[/tex]
Where:
r: It is the radius of the sphere
We are told as data that the diameter of the sphere is 10in, so the radius is 5in:
[tex]V = \frac {4} {3} \pi * 5 ^ 3\\V = \frac {4} {3} \pi * 125\\V = \frac {500} {3} \pi\\V = 523.33in ^ 3[/tex]

what is
(6x-7)+(3x-29)
Answer:
180°
Step-by-step explanation:
(8y+17)°=(6x-7)°
(3x-29)°+(8y+17)°=180°
so,
(3x-29)°+(6x-7)°=180°
To solve the expression (6x-7)+(3x-29), we combine like terms. The 'x' terms (6x + 3x) sum up to 9x and the constants (-7 and -29) sum up to -36. Therefore, the simplified expression is 9x - 36.
Explanation:The student wants to solve the expression (6x-7)+(3x-29). To do this, you should combine like terms, which means you should add together the terms that have the same variable.
Step 1: Add the 'x' terms together. This would give us 6x + 3x which equals 9x.
Step 2: Then add the constants together, in this case -7 and -29, you get -36.
So, the simplified result of the expression (6x-7)+(3x-29) is 9x - 36.
