Mara ran 3 km north and then 4 km east. she will finish her run by running directly home. what was the total distance of her run? a right triangle with side lengths 8 kilometers and 4 kilometers. a point at intersection of the side with length 3 kilometers and the hypotenuse is labeled mara's house. 5 km 7 km 12 km 14 km
Based on the calculations, the total distance of Mara's run is equal to: C. 12 km.
How to determine the total distance of Mara's run.In order to determine the total distance of Mara's run, we would solve for the length of the hypotenuse by applying Pythagorean's theorem and then add it to the other distances.
Mathematically, Pythagorean's theorem is given by this formula:
c² = a² + b²
Where:
c is the hypotenuse.a is the adjacent side.b is the opposite side.Substituting the given parameters into the formula, we have;
c² = 3² + 4²
c² = 9 + 16
c = √25
c = 5 km.
Now, we can determine the total distance of Mara's run:
Total distance = 3 + 4 + 5
Total distance = 12 km.

Step-by-step explanation:
if you combine the radicals, you will receive the answer that is shown above.
Answer:
[tex]-4\sqrt{5}[/tex]
Step-by-step explanation:
Given expression: (square root 5) - (3 square root 5)
⇒ [tex]-\sqrt{5} - 3\sqrt{5}[/tex]Since we have √5 common in both terms, let's factor √5.
⇒ [tex]\sqrt{5} - 3\sqrt{5}[/tex]⇒ [tex]\sqrt{5} \times (-1 - 3)[/tex]Finally, we can simplify;

The expression of Volume in cubic meter [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)
The correct option is (1)
What is Volume?Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.
Volume will be,
V= Volume of rectangular pyramid + Volume of cuboid
Volume of rectangular pyramid= [tex]\frac{1}{3}[/tex] * base area* height
= [tex]\frac{1}{3}[/tex] * 6*8*(10-4)
=[tex]\frac{1}{3}[/tex] * 6*8*6
Volume of cuboid= l*b*h

Find the measures of angles Q and S. Number 7!
Step-by-step explanation:
by the way, you are completely and exactly right at 6.
Q is the inscribed angle of the (inner) arc angle TR.
and as such it is half of that arc angle TR.
S is now on the same side of the circle center as the segment TR. so, we have to flip the situation around :
S is half of the outside arc angle between T and R.
as the sum of the inner and outside arc angles are 360° (the full circle), the sum of half of their values is then
360/2 = 180°
so, yes,
x + 2 + 9x - 7 = 180
10x - 5 = 180
10x = 185
x = 18.5
Q = x + 2 = 18.5 + 2 = 20.5°
S = 9x - 7 = 9×18.5 - 7 = 166.5 - 7 = 159.5°

I need help asap, what is the value of x and the measure of arc CDE?Find the following values for circle P
The value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle shown in the picture.
The angle APE = 90 degree (from the figure)
25x + 15 = 90
25x = 75
x = 3
The measure of arc CDE = (20x + 4) + (33x - 9) = 53x -5
= 53(3) -5
= 154 degree
Thus, the value of the x is 3 and the measure of the arc is 154 degree if the angle APE is 90 degree.

(a) the value of h and of k,
Answer:
Step-by-step explanation:
f(x) = 4-x
g(x) = h[tex]x^{2}[/tex]+k
g(f(x)) = 2[tex]x^{2}[/tex]-16x+26
so put f(x) in g(x)
h[tex](4-x)^{2}[/tex]+k
h((4-x)(4-x) + k
h([tex]x^{2}[/tex]-8x+16)+k
if h = 2 , then
2[tex]x^{2}[/tex]-16x+32 + k
and we want 26 instead of 32 so subtract 6 so K = (-6)

2[tex]x^{2}[/tex]-16x+32 - 6
2[tex]x^{2}[/tex]-16x+26

The amount of profit Gavin made in selling the water bottles at the base ball game is $65.
How to find profit?
He bought 75 bottle water for a total of $25.
He sales all of the bottles for $1.20 each.
Therefore,
profit = selling price - cost price
Hence,
cost price = $25
selling price = 1.20(75) = $90
