What is the value of x in the figure below?
A. 55
B. 22.5
C. 45
D. 57.5
Answer:
45
Step-by-step explanation:
2 angles unconnected to an exterior angle = the exterior angle. In this case
70 + x = 115 Subtract 70 from both sides
70-70+x =115-70 Combine
x = 45
The length of the hypotenuse of a right triangle is 137 units. The length of one leg of the triangle is 105. Gina wrote the following step to find the length of the unknown leg: Length of the unknown leg = 1372 − 1052 = 18,769 − 11,025 = 7,744 units Which statement best explains whether Gina's step is correct or incorrect?
A. It is incorrect because the length of the unknown side is the square root of 29,794.
B. It is incorrect because the length of the unknown side is the square root of 7,744.
C. It is correct because the length of the unknown side is the difference of the lengths of the sides.
D. It is correct because the length of the unknown side is the difference of the squares of the sides
Answer:
B. It is incorrect because the length of the unknown side is the square root of 7,744
Step-by-step explanation:
Givena = 137b = 105c = ?SolutionAs per Pythagorean theorem:
c² = a² - b²c² = 137² - 105² = 18769 - 11025 = 7744c = √7744 = 88 unitsGina's incorrect step is:
B. It is incorrect because the length of the unknown side is the square root of 7,744Answer:
it is incorrect because the length of the unknown side is the square root of 7,744.
Step-by-step explanation:
a^2 + b^2 = c^2
105^2+ b^2 = 137^2
11025+ b^2= 18769
11025-11025+ b^2 = 18769-11025
b^2= 7704
sqr b^2= sqr 7704
b=87.77243303
b=87.8 simplified
therefore,this gina is wrong because the lenght of the unknown leg is the square root of 7,744.
hope it helps.
Describe the transformation of f(x) = x2 represented by g(x)=(x-1)2 + 3, then graph the function
shift right ?______
Shift left ?______
Stretch factor?_____
The transformation has a horizontal shift right by 1 units and vertical shift upwards by 3 units. The graph is shown below.
What do you mean by transformation of a graph ?
The modification of an existing graph or graphed equation to create a different version of the following graph is known as transformation.
The functions given are :
f(x) = x²
and
g(x) = (x - 1)² + 3
Now , we know that , the horizontal shift depends on the value of h. The horizontal shift is described as:
g(x) = f (x + h)
Then , the graph is shifted to left by h units.
and
g(x) = f (x - h)
Then , the graph is shifted to right by h units.
If we compare f(x) with g(x) , their is a difference of -1 , it meant shift is right by 1 units.
Now , we know that , the vertical shift depends on the value of k. The vertical shift is described as:
g(x) = f(x) + k
Then , the graph is shifted up by k units.
and
g(x) = f(x) - k
Then , the graph is shifted down by k units.
Here , if we compare f(x) with g(x) there is addition of 3 in g(x) , this meant the graph is shifted upward by 3 units.
The graph of the function is attached below. Here , both of the functions are graphed.
Therefore , the transformation has a horizontal shift right by 1 units and vertical shift upwards by 3 units. The graph is shown below.

Kayla hikes 25 meters in 13.7 seconds. Which of the following is closest to how far she will hike in 6 minutes , if she maintains the same pace?
A: 650 meters
B: 10 meters
C: 150 meters
D: 9000 meters
Answer: 650
Step-by-step explanation:
25/13.7 = x/360
[cross multiply] : (360)(25)/(13.7)(x)
= 9000/13.7
X=656.9
which is closest to 650
Answer choice for 650
Kyla will hike close to 650 meters in 6 minutes if she maintains the same speed.
What is Proportion?Proportions are defined as the statement when two or more ratios are made to be equal to each other.
Two quantities are said to be directly proportional is they decrease or increase in the same ratio.
If a : b = c : d, then we can write a/b = c/d.
Distance Kyla hikes in 13.7 seconds = 25 meters
We have to find the distance Kyla hikes in 6 minutes.
Here, as the distance increases or decreases, time also increases or decreases. Hence the quantities distance and time are directly proportional.
Let x be the distance covered by Kyla in 6 minutes
Also 6 minutes = 360 seconds
We can write,
25 : 13.7 = x : 360
25/13.7 = x/360
x = (25 × 360) / 13.7
x = 9000 / 13.7
x = 656.9 ≈ 650 meters
Hence Kyla will hike close to 650 meters in 6 minutes.

Answer:
10. x = 16.5 y = 80 degrees
11. x = 4.5 y = 108 degrees
Step-by-step explanation:
To get the length, it multiplied by 1.5, so just multiply 11 by 1.5. The angles are still the same amount.
Length = *1.33333... and 6 x 1.3333... = 4.5. Angle amounts are still the same
Marie works for the electric company. She earns $10 per hour working 40 hours a week.
She gets 1.5 times her pay in overtime for any hours worked over 40 hours. If she
worked 50 hours in a week, how much would Marie make?
0 $400
$1,000
$550
$500
Answer:
$550
Step-by-step explanation:
She worked 50 hours. You can subtract the original 40 hours from that 50 and multiply it by 10 giving her a $400 weekly income. Now, you have to add the overtime hours. She worked 10 extra hours and she is earning 1.5 times her normal hourly pay for these hours. $10 (Her normal hourly pay) times 1.5 is $15 per hour. Now, multiply the number of extra hours by 15. This is a total of $150. So, in total, she earned $550 dollars that week.

The answer is $550

Step-by-step explanation:
Lonnie walks for 30 minutes every day. The graph shows the number of Calories she burns in a week.
Which is true of the graph?
The graph shows the proportional relationship between the number of Calories she burns in a week and miles she walks. The correct option is C.
What is proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.
Given,
Lonnie walks for 30 minutes every day.
The graph shows the number of Calories she burns in a week.
From the graph,
The y -intercept is 0.
Option A is incorrect.
And the graph of line is not y = 100x.
Because at x = 2, y is not 200.
That means, the points should be (2, 200).
But clearly this is not.
To find the proportional relationship:
From the graph, we interpreted two points,
(4, 300) and (3, 600)
Now, the proportional relationship is represented as
x/y = k,
where x and y are two expressions and k is constant.
4/300= 300/4 = 75
And 600/ 8 = 75.
That means, it shows the proportional relationship.
And there is no information about, the more Lonnie walks, the faster she goes.
So, this option is discarded.
Therefore, the correct option is C.
