Ali and billy ran around a race track. How many more metres did Ali ran than billy in one lap? (Find perimeter)
Answers
Answer:
Ali ran 25.13 m more than bily
Step-by-step explanation:
From the diagram, we can see that bully runs with the inner track line while Ali runs with the outer track line.
Thus;
Diameter of inner semi circle = 20 m
Diameter of outer semi circle = 20 + 4 + 4 = 28 m
Perimeter of inner semi circle = πD/2 = 10π
Perimeter of outer semi circle = πD/2 = 14π
Now, perimeter of Billy = 80 + 80 + 10π + 10π = 222.83 m
Perimeter of Ali = 80 + 80 + 14π + 14π = 247.96 m
Thus, in one lap, difference in distance between Ali and billy = 247.96 - 222.83 = 25.13 m

Given: AB=AC m∠1=m∠2 AC=15, DC=5 Find: BD, AB
Answers
Answer:
AB = 15
BD = 5
Step-by-step explanation:
Statement__________________| Reason______________
1) m<1 = m<2, AB = AC | Given
2) AD = AD | Reflexive property
3) ΔABD = ΔADC | Side - angle - side
4) AB = AC = 15 | Corresponding part of congruent triangles . | are congruent
5) BD = DC = 5 | Corresponding parts of congruent triangles . | are congruent
Answer:
BD = 5, AB = 15Step-by-step explanation:
AB = AC and AC = 15 (both given)
⇒ AB = 15AB≅AC, ∠1≅∠2, AD≅AD (first two given and the last one is the common side)
⇒ ΔABD ≅ ΔACD by SASBD≅DC as corresponding sides
BD = DC and DC = 15
⇒ BD = 5Solve the inequality and enter your solution as an inequality comparing the

Answer:
Option (D)
Step-by-step explanation:
Linear equations are in the form of y = mx + b
Here, m = slope of the linear function
b = y-intercept
Quadratic function → y = ax² + bx + c
By these properties, y - 6 = x² represents the quadratic equation which is non linear.
Therefore, Option (D) will be the correct option.

Answer:
x = 6
Step-by-step explanation:
Step 1: Cross multiply.
[tex]\frac{x}{2x+4} = \frac{3}{8} \\x*(8)=3*(2x+4)\\8x=6x+12[/tex]
Step 2: Subtract 6x from both sides.
[tex]8x-6x=6x+12-6x\\2x=12[/tex]
Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} =\frac{12}{2}[/tex]
x=6
Solution:
X/(2x+4) = 3/8
1) Cross -multiply
X * (8) = 3 * (2x+4)
8x = 6x + 12
2) Subtract 6x from both sides
8x - 6x = 6x + 12 - 6x
2x = 12
12/2 = 6
X= 6

When 17 times a number is decreased by the square of the same number, the result is greater than 60. The
number must be between
Answers
Step-by-step explanation:
Let x be the number.
We have 17x - x² > 60.
=> x² - 17x + 60 < 0
=> (x - 5)(x - 12) < 0
=> 5 < x < 12
Hence the number is between 5 and 12, both non-inclusive.
The number must be between [tex]5[/tex] and [tex]12[/tex].
A square number is the result when a number has been multiplied by itself.
Let the number be [tex]x[/tex].
As [tex]17[/tex] times a number is decreased by the square of the same number, the result is greater than [tex]60[/tex],
[tex]17x-x^{2}>60[/tex]
[tex]x^{2} -17x+60<0[/tex]
[tex]x^{2}-12x-5x+60<0[/tex]
[tex]x(x-12)-5(x-12)<0[/tex]
[tex](x-5)(x-12)<0[/tex]
[tex]5<x<12[/tex]
So, the number must be between [tex]5[/tex] and [tex]12[/tex]

Look at the image of the two hangers. Based on the image, what is one thing that must be true? What is one thing that could be true? What is one thing that cannot possibly be true?
Answers
Answer:
One thing that must be true is that the objects will cause some leaning because their masses are unequal, judging from the volume that the objects can hold. One thing that could be true is that the triangle could be heavier than the square, leading to a leaning toward the left. The second pic cannot be true, for there are too much mass concentrated on one side to maintain equilibrium.

30% of 50
what’s the easiest and fastest way to solve it?
Answers
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$50=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations:
$50=100\%(1)$.
$x=30\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{50}{x}=\frac{100\%}{30\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{50}=\frac{30}{100}$
$\Rightarrow x=15$
Therefore, $30\%$ of $50$ is $15$
Answer:
15
Step-by-step explanation:
change the percent to a decimal
30% to .30
