Step-by-step explanation:
Basically 100% means she scored all 50 question correct.
Solution:
100% = 50 questions
1% = 50÷100 = 0.5
92/100 x 50 = 46
Answer: 46
Answer:
Answer: 46Step-by-step explanation:
percentage scored = 92
number of correct question = x
total number of questions = 50
The formula for calculating the percentage scored
= number of correct question / total number of questions x 100
That is
92 = \frac{x}{50}
50
x
x \frac{100}{1}

dividing through by 100 , we have
x = 46x=46Therefore, she got 46 questions right

What is Distributive property?It means to divide something. when a same number a multiplied with sum or subtraction of any numbers than we can divide that or distribute that.
For example: (a+b)*(c+d) = (a+b)*c+(a+b)*d
What is the mistake?While distributing (X-2)(3X) + (X-2)(4) sign remains the same Whereas she changed the sign form - to + which is incorrect.
How to solve?(X-2)(3x) + (X-2)(4)
(x)(3x) + (-2)(3x) + (x)(4) + (-2)(4)

Answer:
circley-axis5 unitsStep-by-step explanation:
It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.
The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.

Answer:
5). x = 15
7). JL = 78
Step-by-step explanation:
We can solve these problems with the help of midsegment theorem.
Midsegment theorem:
"Segment joining midpoints of two sides of a triangle is parallel and half the measure of third side of the triangle"
Question 5
8x - 23 = [tex]\frac{1}{2}(10x+44)[/tex]
8x - 23 = 5x + 22
8x - 5x = 22 + 23
3x = 45
x = 15
Therefore, x = 15 is the answer.
Question 7
Since, MN is the midsegment,
MN = [tex]\frac{1}{2}(JL)[/tex]
5x - 16 = [tex]\frac{1}{2}(4x+34)[/tex]
5x - 16 = 2x + 17
5x - 2x = 17 + 16
3x = 33
x = 11
Therefore, Length of JL = 4(11) + 34
= 44 + 34
= 78 units

A cyclist rode 15 miles south and 20 miles west. If she takes a diagonal route
back to her starting point, how many mile will she have to travel?
Answer:
25 miles
Step-by-step explanation:
you can use the Pythagorean Theorem and let the legs be 15 and 20, the diagonal (c) is the hypotenuse
15² + 20² = c²
225 + 400 = c²
625 = c²
c = [tex]\sqrt{625}[/tex] = 25

Laila purchased a prepaid phone card for $25 . Long distance calls cost 24 cents a minute using this card. Laila used her card only once to make a long distance call. If the remaining credit on her card is $13.72 , how many minutes did her call last?
Answer:
The call lasted for 47 minutes.
Step-by-step explanation:
It is given that:
Value of prepaid card = $25
Cost per minute of long distance call = 24 cents = $0.24
Remaining credit = $13.72
Let,
x be the number of minutes
y be the remaining amount
y = 25 - 0.24x
13.72 = 25 - 0.24x
0.24x = 25 - 13.72
0.24x = 11.28
Dividing both sides by 0.24
[tex]\frac{0.24x}{0.24}=\frac{11.28}{0.24}\\x=47[/tex]
Therefore,
The call lasted for 47 minutes.
