Determine all the unknown values of the figure Devon is hired by the city to create a scale mural of a local park. Devon is exactly 6 feet tall but in the mural, he is 4.5 feet tall. If the tree in the park is 30 feet tall, how tall should the tree be in the mural?
The tree will be feet tall in the mural.
Answer:
F=10, S=26
Step-by-step explanation:
We know that the base is 24. Using that information, 10^2+24^2=26^2 which is a pythagorean triple
The height of the tree in the mural should be 22.5 feet.To determine the height of the tree in the mural, we can set up a proportion using the given information:
Devon's height in the mural: 4.5 feet
Devon's actual height: 6 feet
Tree's height in the mural: Unknown (let's denote it as x)
Tree's actual height: 30 feet
The proportion can be set up as follows:
(Devon's height in the mural) / (Devon's actual height) = (Tree's height in the mural) / (Tree's actual height)
(4.5 feet) / (6 feet) = x / (30 feet)
Now, let's solve for x by cross-multiplying:
4.5 feet * 30 feet = 6 feet * x
135 feet = 6x
Now, divide both sides of the equation by 6 to find x:
x = 135 feet / 6
x = 22.5 feet
So, the height of the tree in the mural should be 22.5 feet.

if x=-5,0,4,8,13 and y=-7,3,11,19,29 what is the slope of the line
The slope of the line is 1/2.
What is slope?The slope is a measure of the steepness of a line, or a section of a line, connecting two points.
Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.
For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).
Given:
x=-5,0,4,8,13 and y=-7,3,11,19,29
To find the slope
m= (0-(-5))/(3-(-7))
m=0+5/ 3+7
m=5/10
m= 1/2

The probability that she selects all 4 blue disks is 0.0317.
What is probability?The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Now, according to the question;
There is a total of 2 green disks.
There is a total of 4 blue disks.
There is a total of 3 yellow disks.
The formula for selecting the combination of 4 blue disks are
Probability = (combination for 4 blue)/ Total combination for 9.
The combination is given by the relation;
ⁿCₓ = n!/{x!(n-x)!}
The combination for getting 4 blues is-
n is the total blue disks = 9
x is the selected blue disks = 4

Significantly high values are

Is a pulse rate of 92.3 beats per minute significantly low or significantly high?
beats per minute or higher.
OA. Significantly low, because it is more than two standard deviations below the mean
OB. Neither, because it is within two standard deviations of the mean
OC. Significantly high, because it is more than two standard deviations above the mean
OD. It is impossible to determine with the information given
B. Neither, because it is within two standard deviations of the mean.
Given; A certain group of test subjects had pulse rates with a mean of 78.9 beats per minutes.
Standard deviation of 11.7 beats per minute.
Range Rule of Thumb:
Standard deviation = Range/4.
Range = 4×SD.
= 4×11.7
= 46.8
The "usual" range for this situation is,
78.9-2(11.7) to 78.9+2(11.7) = 55.5 to 102.3
Significantly low will be less than 55.5
Sig high will be greater than 102.3
Pulse rate - Mean = 92.3 - 78.9 = 13.4
This value below mean
Then check 2×Standard deviation = 2×11.7= 23.4
This value is also below the mean value.
Significantly low values are 55.5 beats per minute or lower.
Significantly high values are 102.3 beats per minute or higher.
Hence it is within two standard deviations of the mean.
Therefore, the answer is B Neither, because it is within two standard deviations of the mean.

Answer: y= -2/3 x + 1/3
Step-by-step explanation:
The first thing you need to do is but it into standard y = mx + b form, where m is the slope of the line and b is the y-intercept. Using algebra, we can turn 3y + 2x = 1 into y = -2/3x + 1/3. the slope is -2/3 which means you start at the y-intercept (0,1/3) and go down 2 and to the right 3. Putting it on paper or in a graphing simulator will give you this line. The point on the y-axis is the y-intercept and the point on the x-axis is the x-intercept.
Answer:
make 3y subjet of the fomulae then subtract 2x then divide by 3 both sides then the ans will be y= -2x+1/3

Jordan and Ellen recycle cans. Jordan recycles 7 cans for every 12 cans Ellen recycles. Last week, Jordan recycled 42 cans.
What number, c , can be multiplied by 12 to determine the number of cans Ellen recycled last week? How many total cans did Jordan and Ellen recycle last week?
Answer:
c = 6
Total: 114
Step-by-step explanation:
The ratio of the number of cans Jordan recycles to the number Ellen recycles is 7:12.
The ratio of the number of cans Ellen recycles to the number of cans Jordan recycles is 12:7.
Jordan recycled 42 cans.
Ellen recycled 42 × 12/7 = 6 × 12
c × 12 = 6 × 12

Which word not be a step in solving 18=2(4+x)
The correct option is B) Collect variables terms on one side because there is one value for the variable.
What is defined as the variables?In the perspective of a math concept or experiment, a variable is a quantity that really can change. A variable is typically represented by a single letter. Variables are commonly represented by the alphabets x, y, and z. We will sometimes select a letter which further tells us of the quantity this represents, including such t for time, v voltage, and any b for bacteria.The given equation in this case is,
18 = 2(4+x)
By using the Distributive property on the right side,
18 = 8 + 2x
After subtracting 8 from both sides ( Isolating variable x )
18 - 8 = 8 + 2x - 8
Compile similar terms,
10 = 2x
By dividing both sides by two ( Isolating variable x )
x = 5
As a result of the preceding explanation, it is completely obvious that we utilized all options but apart from option B.

All sets that √7 belong to irrational numbers
The number √7 is a number inside a square root. Also, note that the number 7 is a whole number, but not a perfect square. Therefore, by our rule, we have that √7 belongs to the set of real numbers and to the set of irrational numbers.
In mathematics, the irrational numbers (from in- prefix assimilated to ir- (negative prefix, privative) + rational) are all the important numbers that are not rational numbers.
That is, irrational numbers can't be expressed as the ratio of two integers. When the ratio of lengths of two line segments is a real number, the road segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there's no length ("the measure"), regardless of how short, that would be used to express the lengths of both of the two given segments as integer multiples of itself.
Among irrational numbers are the ratio π of a circle's circumference to its diameter, Euler's number e, the golden ratio φ, and therefore the square root of two. In fact, all square roots of natural numbers, aside from perfect squares, are irrational.
Like all real numbers, irrational numbers are often expressed in positional notation, notably as decimal numbers. within the case of irrational numbers, the decimal expansion doesn't terminate, nor end with a repeating sequence.
for instance, the decimal representation of π starts with 3.14159, but no finite number of digits can represent π exactly, nor does it repeat.
Conversely, a decimal expansion that terminates or repeats must be a real number. These are provable properties of rational numbers and positional number systems and aren't used as definitions in mathematics.

m< 1=3x° and m2 = (x+48)°
If the two angles are supplementary then the value of x is 33°.
Two angles that sum to a straight angle or 180° are called supplementary angles.
The non-shared sides of two supplementary angles that are nearby create a straight line if they share just one side and have a common vertex. A linear pair of angles is the name given to such angles. However, extra angles might be spaced apart and need not be on the same line. For instance, opposite angles of a cyclic quadrilateral (one whose vertices all fall on a single circle) and adjacent angles of a parallelogram are supplementary.If the two given angles are supplementary then we can create a linear equation in x of the form:
m∠1+m∠2=180°
Substituting the values we get:
3x°+(x+48)°=180°
or, 4x°+48°=180°
or, 4x°=180°-48°
or,4x°=132°
or, x°=33°
Hence the value of x is 33°.
