If the measure of an angle is 13º, find the measure of its supplement.
Answer:
167°
Step-by-step explanation:
The supplement of an angle will always be the measure of an angle, when added to the original, will equal 180°.
If we know the measure of 1 of these angles, we can easily find the measure of the other, assuming x is the missing angle measure.
[tex]13+x=180[/tex]
We can subtract 13 from both sides to get the value of x.
[tex]13+x-13=180-13\\\\x=167[/tex]
Hope this helped!
Answer:
167
Step-by-step explanation:
Supplementary angles add to 180
x+13 = 180
Subtract 13 from each side
x = 180-13
x =167
The supplement to 13 is 167

The scale for a map to actual distance is 2 cm to 100 mi. The driving distance on the map between Los Angeles and Las Vegas is 5.4 cm. What is the actual distance, in miles, between Los Angeles and Las Vegas?
Answer: 270 miles
Step-by-step explanation:
From the question, we are informed that the scale for a map to actual distance is 2 cm to 100 mi and that the driving distance on the map between Los Angeles and Las Vegas is 5.4 cm.
The actual distance, in miles, between Los Angeles and Las Vegas will go thus:
= 5.4cm/2cm × 100mi
= 2.7cm × 100miles

Brad gets an allowance of $16 each week, and his younger sister Samantha gets an allowance of $9 each week. Brad saves one-half of his allowance, and Samantha saves two-thirds of her allowance. Suppose Brad started with $0 savings, and Samantha started with $40. How many weeks will it take until they have the same amount in savings?
Answer:
20 weeks
Step-by-step explanation:
To be able to find the amount of weeks that it will take them to have the same amount, you can say that the amount that Brad saves each week for the number of weeks is equal to the amount that Samantha saves each week for the number of weeks plus the initial amount she has:
(16*1/2)*x=((9*2/3)*x)+40, where
x is the number of weeks
Now, you have to solve for x:
8x=6x+40
8x-6x=40
2x=40
x=40/2
x=20
According to this, the answer is that it will take them 20 weeks to have the same amount in savings.

What was his average speed (km/h)?
Answer:
10 km/h
Step-by-step explanation:
First, convert 150 minutes to hours:
150/60
= 2.5 hours
Then, to find his speed, divide the km by the number of hours:
25/2.5
= 10 km/h
Answer:
10 km / hr
Step-by-step explanation:
We want to find the average speed in kilometers per hour.
We know that Andre cycled 25 kilometers in 150 minutes.
First, we have the convert 150 minutes to hours.
There are 60 minutes in 1 hour, so we can divide 150 by 60.
150/60= 2.5
Next, find the average speed in kilometers per hour.
Divide the kilometers traveled by the hours.
speed = kilometers / hours
Andre cycled 25 kilometers in 2.5 hours.
speed= 25 km /2.5 hrs
speed = 10 km/hr
Andre’s average speed was 10 kilometers per hour.

The smith want to fence their square garden which has an area of 289 square feet what would be the minimum amount of fencing needed to complete the project
Answer:
The minimum amount of fencing needed to complete the project = 68 feet
Step-by-step explanation:
The garden is a square
Let the sides of the square be L
area of square = L × L = L² = 289 square feet
L² = 289 sq ft
L = √(289
L = 17 feet
This means that each side of the garden has a dimension of 17 ft.
Ince a square has 4 equal sides, to calculate the minimum amount of fencing needed, we will find the total length of the 4 sides of the garden, which is the perimeter of the garden:
Perimeter of a square = 4 × L
= 4 × 17
= 68 feet
Therefore, minimum amount of fencing needed = 68 feet

Answer:
1) when tomato patch is 6.5 feet the area is 191.75 sq.ft
2) when tomato patch is 7 feet the area is 217 sq.ft
3) when area is 338 sq.ft the tomato patch is 9.0778 feet
4) when area is 147.25 sq.ft the tomato patch is 5.543799 feet
Step-by-step explanation:
The given equation is :
3x^2 + 10x
Length of Tomato (in feet) x, 6.5 , x , 7
Patch Area of Vegetable Garden (in square feet) 338, x , 147.25, x
So we can find the missing terms with the help of the equation 3x^2 + 10x
Putting the values of x from the length of the tomato patch
1) 3x^2 + 10x= 3(6.5)²+ 10 (6.5)=126.75+ 65= 191.75 square feet
2) 3x^2 + 10x= 3(7)² +10 (7)= 147+70= 217 square feet
So the area of her vegetable garden for a variety of lengths of the tomato patch= 6.5 feet is 191.75 square feet
and for 7 feet is 217 square feet
Similarly we can find the length of the tomato patch from the area by again using the given equation 3x^2 + 10x
So when area = 338 square feet
The equation becomes
3x^2 + 10x= 338
Rearranging it : 3x^2 + 10x-338 =0
This is a quadratic equation and can be solved with the help of the formula.
Here a= 3, b= 10 and c= -338
x = -b±√b²- 4ac/2a
Putting the values of a,b,c we get
x= -10±√100+ 4056/6
x= -10± 64.467/6
x= 54.467/6 or -74.467/6 we ignore the negative value because the garden cannot have the negative area.
x= 9.0778 feet
Similarly repeating the same process would give
So when area = 147.25 square feet
The equation becomes
3x^2 + 10x= 147.25
Rearranging it : 3x^2 + 10x-147.25 =0
This is a quadratic equation and can be solved with the help of the formula.
Here a= 3, b= 10 and c= - 147.25
x = -b±√b²- 4ac/2a
Putting the values of a,b,c we get
x= -10±√100+ 1767/6
x= -10± 43.208/6
x= 33.208/6 or -53.208/6 we ignore the negative value because the garden cannot have the negative area.
x= 5.543799 feet
A circle has a circumference of 100 yd. Find its area.
Answer:
Area = 794.23 yd²Step-by-step explanation:
In order to find the area of the circle we must first find it's radius using the circumference
Circumference of a circle = 2πr
where
r is the radius
From the question
Circumference = 100 yd
So we have
100 = 2πr
Divide both sides by 2π
We have
[tex]r = \frac{100}{2\pi} \\ = \frac{50}{\pi} \\ = 15.91549[/tex]
We have
radius = 15.9 yd
Since we've found the radius we can use it to find the area
Area of circle = πr²
Area = (15.9)²π
Area = 252.81
= 794.226
We have the final answer as
Area = 794.23 yd² to 2 decimal places

Slope m = -5 y= intercept -4 What is the equation?
Answer:
[tex]\huge\boxed{y = -5x - 4}[/tex]
Write an equation in the format y = mx + b, or the slope-intercept formula, where:
m = slope
b = y-intercept
Plug in the values given:
y = (-5)x + (-4)
Simplify:
y = -5x - 4. This is the equation in slope-intercept form.
Answer: y=-5x-4
Step-by-step explanation:
Slope intercept form is y=mx+b
Since m represents slope you will plug in -5 because that is your slope.
Since b represents the y-intercept, you will plug in -4 after y=-5x
so therefore your equation is y=-5x-4

If BD= 14 and CD= 4, then BC= ?
Remember that a segment that connects two points A and B is written as:
AB
Now, assuming that in this case the points B, D, and C are collinear, we can see that C is between B and D.
With this, we can find that BC = 10
Then we can write:
BD = BC + CD
And we know that:
BD = 14
CD = 4
we can replace thest two in the above equation to get:
14 = BC + 4
14 - 4 = BC
10 = BC
We just found that the value of the segment BC is 10.
