The scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.
To determine the scale used by Johnny for the drawing, we need to compare the measurements in the drawing to the actual measurements of the soccer field. We can set up a proportion to find the scale.
Let's denote the scale as x (the ratio of the drawing measurements to the actual measurements). According to the information provided, the width of the soccer field in the drawing is 6 millimeters, while the actual width is 60 meters.
We can put up the following proportion using the scale:
6 millimeters / x = 60 meters / 1
We can solve for x by cross-multiplying and then dividing:
6 millimeters * 1 = 60 meters * x
6 = 60x
Dividing both sides by 60:
6 / 60 = x
1 / 10 = x
Therefore, the scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.

Given that;
The minute hand is pointing to the 4.
Now,
Since, The minute hand is pointing to the 4.
Hence, The value of number after pointing to 20 minutes later is,
We know that;
Every 5 minutes gives 1 point.
⇒ 20 / 5
⇒ 4
Thus, The minute hand is pointing to 20 minutes later is,

Write an equation for the line that contains (-15, -8) and is parallel to the
graph -3x + 5y = -8
Answer:
y=3/5x+1
Step-by-step explanation:
Hi there!
We are given the equation -3x+5y=-8 and we want to find the equation of the line that is parallel to -3x+5y=-8 and contains the point (-15,-8)
parallel lines have the same slopes, but different y intercepts.
So let's first find the slope of -3x+5y=-8
We can do this by converting the equation from standard form (ax+by=c where a, b, and c are free coefficients (numbers)) to slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)
add 3x to both sides
5y=3x-8
divide by 5 on both sides
y=3/5x-8/5
3/5 is in the place of where m is, so that means that 3/5 is the slope of the line
we can write the equation of the new line in slope-intercept form.
Here it is so far:
y=3/5x+b
we need to find b
Because the line will pass through the point (-15,-8), we can use it to solve for b
substitute -15 as x and -8 as y
-8=3/5(-15)+b
multiply
-8=-9+b
add 9 to both sides
1=b
substitute 1 as b into the equation
y=3/5x+1
There's the equation of the line :)

There is a relationship between the total cost of renting a costume and the number of hours the costume is rented.
For 2 hours, the total cost is $50
For 5 hours, the total cost is $80
What type of variation is this relationship [ Direct or Partial] and what is the initial value?
Answer:
this means that for just an hour or 2 you're going to pay $25/hour which would be the initial value...but if you keep it for 5 hours you only pay $16/hour...the more you buy the less you pay per thing you're buying. ...this is a partial relationship, because there is an initial value greater than 0, and has a constant rate of change. a direct relationship would be when one variable did affects the other, meaning when one changes, so does the other ....it would mean the price got cheaper by a certain amount with every hour added ...in this example, the price doesn't get cheaper until hour 5, meaning the initial value is affected by the variable of hours rented...but is not a constant change, it is a partial change because it only changes under certain circumstances, (5 hours) rather than changing constantly with each passing hour....

find the height x of the tree
Answer:
19.8 m
Step-by-step explanation:
To find the height of the tree, we can use the trig ratio tangent:
θ = angle, h = height
tan θ [tex]= \frac{opposite}{adjacent}[/tex]
tan 33° = h / 30.5
h = (tan 33°)(30.5)
h = (0.6494)(30.5)

Answer:
80% increase
Step-by-step explanation:
First, divide $0.25/$0.45, you get 0.8, turn it into a percent. 0.8=80%
There is an 80% increase.
Check work:
0.25x1.8=0.45
We multiply by 1.8 because 80% increase means 100% (itself) multiplied by 80% of itself, which gives us 180% or 1.8.
0.25x1.8=0.45 ✔️

Given right triangle ABC= with altitude BD drawn to hypotenuse AC. If AD=3 and, AC=27, what is the length of AB?
Given:
In a right angle triangle ABC, altitude BD drawn to hypotenuse AC.
AD=3 and, AC=27.
To find:
The length of AB.
Solution:
Draw a figure by using the given information as shown below.
In triangle ABC and ADB,
[tex]\angle ABC\cong \angle ADB[/tex] (Right angles)
[tex]\angle BAC\cong \angle DAB[/tex] (Common angle)
[tex]\triangle ABC\sim \triangle ADB[/tex] (AA similarity postulate)
We know that the corresponding parts of congruent triangles are proportional. So,
[tex]\dfrac{AC}{AB}=\dfrac{AB}{AD}[/tex]
After substituting the given values, we get
[tex]\dfrac{27}{AB}=\dfrac{AB}{3}[/tex]
[tex]27\times 3=AB\times AB[/tex]
[tex]81=AB^2[/tex]
Taking square root on both sides, we get
[tex]\sqrt{81}=AB[/tex]
[tex]9=AB[/tex]
Therefore, the length of AB is 9 units.

stay safe healthy and happy...Roman runs 3 miles every morning. His mean time is 24.7 minutes and his standard deviation is 3.2 minutes. Which of the times is the least likely for Ramon to get?
Answer:
His time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.
Step-by-step explanation:
With an standard deviation of 3.2 minutes, it is clear that the maximum time taken by Roman to complete his run of 3 miles would be
Average time + standard deviation = 24.7 minutes + 3.2 minutes = 27.9 minutes
The minimum time taken by Roman to complete his run of 3 miles would be
Average time - standard deviation = 24.7 minutes - 3.2 minutes = 21.5 minutes
Hence, his time would be least likely greater than 27.9 minutes or smaller than 21.5 minutes.

***11. Two angles form a linear pair. The measure of one angle is 24° more than the
measure of the other angle.
Answer:
The angles are 78° and 102°.
Step-by-step explanation:
Let the one angle is y and the other number if y + 24.
The sum of the angles of the linear pair is 180°.
So, according to the question
y + y + 24 = 180
2 y = 180 - 24
2 y = 156
y = 78°
So, one angle is 78° and the other is 78° + 24° = 102°.

Step-by-step explanation:
24+13+15+10+15+10=87, the total amount of M&M's.
24 are brown, so 24/87 chance that he will draw a brown one.
24/87 = 8/29 simplified.
N which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?
Answer:
53,901
Step-by-step explanation:
Here is the complete question :
In which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?
43,567
45,248
53,901
562,011
In the number 245,093 :
3 = units
9 = tens
0 = hundred
5 = thousand
4 = ten thousand
2 = hundred thousand
the value of 5 in the number is 5000. the number that would have a value that it 10 times greater than 5 in 245,093 must occupy the value of ten thousand.
looking through the options, it is only in 53,901 that 5 occupies a value of ten thousand

In a triangle HIJ, i = 6.6 inches, j = 6.4 inches and Angle,H=62º. Find the length of h, to the
nearest 10th of an inch.
Answer:
7.6 inches
Step-by-step explanation:
We solve the above question using the Law of Cosines.
The formula is given as:
h² = i² + j² - 2ij Cos H
h = √i² + j² - 2ij Cos H
From the above question:
i = 6.6 inches
j = 6.4 inches
Length h = ?
Angle H=62º.
Hence:
h= √6.6² + 6.4² - 2 × 6.6 × 64 × Cos 62
h = √43.56 + 40.96 - 84.48 × Cos 62
h = 7.64292 inches
Approximately to the nearest tenth, Length h = 7.6 inches

For the function g(x)= -2/3x+5, determine x when g(x) = 25
Answer:
x = -30
Step-by-step explanation:
g(x)= -2/3x+5
Let g(x) = 25
25= -2/3x+5
Subtract 5 from each side
25-5= -2/3x+5-5
20 = -2/3x
Multiply each side by -3/2
-3/2 * 20 = -3/2 * -2/3 x
-30 = x
Answer:
x = -30
Step-by-step explanation:
g(x)= -2/3x+5
25 = -2/3x + 5
20 = -2/3x
x = -30

Which is the correct slope-intercept equation for a line that passes through the points (1,-3) and (-3,17)
Answer:
[tex]y=-5x+2[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that the line passes through are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (1,-3) and (-3,17)
[tex]=\frac{17-(-3)}{-3-1}\\=\frac{17+3}{-3-1}\\=\frac{20}{-4}\\=-5[/tex]
Therefore the slope of the line is -5. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-5x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-5x+b[/tex]
Plug in one of the given points and solve for b
[tex]-3=-5(1)+b\\-3=-5+b[/tex]
Add 5 to both sides of the equation to isolate b
[tex]-3+5=-5+b+5\\2=b[/tex]
Therefore, the y-intercept of the equation is 2. Plug this back into [tex]y=-5x+b[/tex]:
[tex]y=-5x+2[/tex]
