Joni and Lori began running from the same point. Joni ran 5 miles west while Lori ran 7 miles north. How far apart were they when they finished
The distance they finishes is 8.6 miles
Given that miles run by Joni is 5 miles and the miles ran by Lori is 7 miles
We need to find the distance they finished
To calculate the total distance along the diagonal line, the Distance Formula first squares the differences between the two x coordinates and the two y coordinates, then adds those squares, and finally calculates their square root.
We know that
According to the Distance formula
= [tex]\sqrt{(5)2+(7)^2}[/tex]
= [tex]\sqrt{25+49}[/tex]
= [tex]\sqrt{74}[/tex]
= 8.6 miles

Use the distributive property with factoring to find the equivalent expression. 20a + 28b = ( a + 7b)
The equivalent expression after factoring 20a + 28b = ( a + 7b) using the distributive property is 19a + 21b = 0.
What is Distributive Property?According to the distributive property, an expression in the form A (B + C) can be solved as A (B + C) = AB + AC. This distributive law applies to subtraction as well and is written as A (B - C) = AB - AC. This means that operand A is shared by the other two operands.
The given equation is 20a + 28b = ( a + 7b).
20a + 28b = ( a + 7b).
Now, subtract both sides by a.
20a - a + 28b = a + 7b - a.
19a + 28b = 7b.
Now, subtracting both sides by 7b.
19a + 28b - 7b = 7b - 7b.
19a + 21b = 0.
Therefore, the equivalent expression to 20a + 28b = ( a + 7b) is 19a + 21b = 0.

Which recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously?
f(n + 1) = f(n) + 1.5
f(n + 1) = f(n) + 0.75
f(n + 1) = one-halff(n)
f(n + 1) = three-halvesf(n)
The recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously is f(n + 1) = f(n) + 0.75
Recursive functionsThe general recursive function is expressed as:
an+1 = d + an
where
r is the common difference
Given the sequence below
1.5, 2.25, 3.0, 3.75, ...
Common difference = 2.25 - 1.5 = 0.75
Substitute
f(n + 1) = f(n) + d
f(n + 1) = f(n) + 0.75

O 0.077
0.004*
O 0.0059
O 0.001
Answer: 0.0059 (choice C)
Explanation:
There are 4 jacks out of 52 cards total.
4/52 = 1/13 is the probability of getting a jack.
The same applies to an ace as well.
The probability of a jack followed by an ace is (1/13)*(1/13) = 0.0059 approximately, when we replace the first card. If the replacement wasn't done, then the second probability would be different from 1/13.
An angle of measure 120 degrees intersects the unit circle at point (-1/2,√3/2) What is the exact value of cos(120)
The exact value of cos120 if the measure 120 degrees intersects the unit circle at point (-1/2,√3/2) is 0.5
Solving trigonometry identityIf an angle of measure 120 degrees intersects the unit circle at point (-1/2,√3/2), the measure of cos(120) can be expressed as;
Cos120 = cos(90 + 30)
Using the cosine rule of addition
cos(90 + 30) = cos90cos30 - sin90sin30
cos(90 + 30) = 0(√3/2) - 1(0.5)
cos(90 + 30) = 0 - 0.5
cos(90 + 30) = 0.5

Step-by-step explanation:
Area of the rectangle is 15*20=300
Area of the triangle is 8*17/2=68
Total area is 300+68=368
Perimeter is 15+20+20+8+17=80
Answer:
[tex]\rm {P = 80 \space\ feet,\space\ A = 360 \space\ square \space\ feet}[/tex]
Step-by-step explanation:
The perimeter of a shape is the sum of all the sides of the shape.
• Perimeter of the polygon = 15 + 20 + 17 + 8 + 20
= 80 feet
To find the area of the polygon, we can separately find the areas of the triangle and the rectangle and then add them together.
• Area of rectangle = length × breadth
= 15 × 20
= 300 square feet
• Area of triangle = [tex]\frac{1}{2}[/tex] × base × height
As the height of the triangle is not provided, we have to calculate it.
Let the height of triangle = [tex]x[/tex]
Using Pythagoras's theorem:
[tex]x^2 + 8^2 = 17^2[/tex]
⇒ [tex]x^2 = 17^2 - 8^2[/tex]
⇒ [tex]x = \sqrt{17^2 - 8^2}[/tex]
⇒ [tex]x=\bf15[/tex]
Now using this value of height, we can find the area of the triangle:
Area of triangle = [tex]\frac{1}{2}[/tex] × 8 × 15
= 60 square feet
• Finally, we can add the areas of the triangle and rectangle together to find the area of the polygon:
Area of polygon = 300 + 60
= 360 square feet
