Mike scored a 125 at a semi-final dividing competition season. He scored 95 at this final season. What is the percentage decrease in kc score?
Answer:
There was a 24% decrease
Step-by-step explanation:
Percentage decrease = (final season's score - semi-final score) / semi final score x 100
[tex]\frac{95-125}{125}[/tex] ×100
[tex]\frac{-30}{125}[/tex] × 100 = -24%

Answer:
X= 42 degrees
Step-by-step explanation:
When combining 3x+12 and x, this results in a 180 degree angle to be formed. Therefore create the equation 3x+12+x=180 to get the value of X.
3x+12+x=180
4x+12=180
-12. 12
4x= 168
x= 42

A shipping container has a volume of 48 cubic meters. What could be the dimensions (length, width, height) of the container if none of the dimensions are 1 m? Explain how you found the dimensions.
Answer:
6m * 4m * 2m
Step-by-step explanation:
Given that :
Cubic volume = 48 m³
Possible dimension if none of the dimensions is 1 m
Volumetric Dimension = (length * width * height)
The product of the three dimensions must give 48m³
Constraint : none of the dimensions has a volume of 1 m.
Hence, possible dimension :
6m * 4m * 2m = 48m²
Hence, one possible dimension is :
6m * 4m * 2m
Consider this expression. x-4/2(x+4)
Answer:
Option A
Step-by-step explanation:
We will simplify the expressions given in the options first,
x² - 16 = (x - 4)(x + 4)
2x + 8 = 2(x + 4)
x² + 8x + 16 = (x + 4)²
Option A
[tex]\frac{x^2-16}{2x+8}[/tex] × [tex]\frac{x+4}{x^2+8x+16}[/tex]
= [tex]\frac{(x+4)(x-4)}{2(x+4)}\times \frac{(x+4)}{(x+4)^2}[/tex]
= [tex]\frac{x-4}{2(x+4)}[/tex]
Option B
[tex]\frac{2x+8}{x^2-16}[/tex] ÷ [tex]\frac{x^2+8x+16}{x+4}[/tex]
= [tex]\frac{2(x+4)}{(x+4)(x-4)}[/tex] ÷ [tex]\frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{2}{(x-4)}\times \frac{1}{(x+4)}[/tex]
= [tex]\frac{2}{x^2-16}[/tex]
Option C
[tex]\frac{x^2-16}{2x+8}[/tex] ÷ [tex]\frac{x+4}{x^{2}+4x+16}[/tex]
= [tex]\frac{(x-4)(x+4)}{2(x+4)}\times \frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{(x-4)(x+4)}{2}[/tex]
Option D
[tex]\frac{2x+8}{x^2-16}\times \frac{x^2+8x+16}{x+4}[/tex]
= [tex]\frac{2(x+4)}{(x-4)(x+4)}\times \frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{2(x+4)}{(x-4)}[/tex]
Therefore, Option A is the answer.

What is the measure of the missing angle?
Answer:
79 degrees
Step-by-step explanation:
You add the two angles and get 79. Then you subtract it from 180 because it is a straight angle. 180-101=79
Answer:
79
Step-by-step explanation:
28+73+x=180
a straight line is 180. That's how I got what it is equal to.
28+73= 101
101+x=180
subtract
180-101= 79

Which proportion can be used to find the arc length, s, in units?
Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s = [tex]\frac{150}{360}(2\pi )(42)[/tex]
[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]
[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]
Therefore, Option B will be the answer.
Help I don’t get it..
Answer:
Step-by-step explanation:
the shape looks like a cube.. and maybe they say something about that outside of the picture, even but assuming that it is a cube, we know all the sides are the same.
we also know that the area of one side of the cube is 3 [tex]\frac{1}{4}[/tex]
so multiply that
W x L = area
3 [tex]\frac{1}{4}[/tex] * 3 [tex]\frac{1}{4}[/tex] = area
10 [tex]\frac{9}{16}[/tex] = area
10.5625 = area
those two answer above are the same .. just one is in fractions and one is in decimals
there are 6 sides on a cube, so multiply the above answer by 6
6* answer = 63.375
63 [tex]\frac{3}{8}[/tex] ( this is your answer)
both of those are also identical , but look different for the reasons I mentioned above
use which ever from seems better to you. :)

If you had a right triangle with legs measuring 40 yards and 100 yards long,
what would be the length of the hypotenuse? Round your answer to the
nearest yard if necessary. *
70 yd
92 yd
108 yd
146 yd
9514 1404 393
Answer:
(c) 108 yd
Step-by-step explanation:
For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...
c² = a² +b²
Solving for c, we have ...
c = √(a² +b²)
c = √(40² +100²) = √(1600 +10000) = √11600
c ≈ 107.70 . . . . yards
The length of the hypotenuse is about 108 yards.

Three squares each have sides of length 6 units and overlap each other as shown below. The points where the sides cross are midpoints. Find the area of the gray figure in square units.
Answer:
90
Step-by-step explanation:
Partition the figure by extending the sides of the ``middle'' square as shown at the right. Each original square contains four $3 \times 3$ small squares. The shaded figure consists of ten $3 \times 3$ squares, so its area is $10 \times 9 = \boxed{90\text{ square
units}}$.
In this exercise we have to use the knowledge of areas to calculate the area of the square in gray, so we have that:
[tex]A=90[/tex]
First it is informed that one side of the square is 6, so every square has exactly:
[tex]l^2=6^2=36[/tex]
Adding that we have 3 squares with the same value of sides:
[tex]36*3=108[/tex]
However, there are areas that are being calculated twice in the central square, these areas are smaller squares that have side values equal to 3, so:
[tex]l^2=3^2=9\\9*2=18\\108-18=90[/tex]

Which value of x results in equal outputs for
j(x) = 3x − 2
and b(x) = |x + 2|
Answer:
Step-by-step explanation:
J(x)=b(x)
3x-2=|x+2|
3x-2=±(x+2)
when 3x-2=x+2
3x-x=2+2
2x=4
x=4/2=2
when 3x-2=-(x+2)
3x-2=-x-2
4x=-2+2=0
x=0
it is rejected as 0-2≠|0+2|
or -2=2
so x=2

Solve the triangle in the figure.
Question options:
A)
BC = 9; m∠A = 53.1°; m∠B = 6.9°; m∠C = 90°
B)
BC = 11; m∠A = 42.8°; m∠B = 47.2°; m∠C = 90°
C)
BC = 19; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Answer:
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Step-by-step explanation:
15²-12² = 9²
BC = 9
sin B = 12/15 = 0.8
∠B = 53.1°
The solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.
The triangle ABC is a right triangle. The new path is in front of the right angle, therefore it is the hypotenuse. To find the length of the hypotenuse we use the Pythagorean theorem:
H² = P² + B²
The length BC will be calculated as below:-
15²-12² = 9²
BC = 9
The angle B will be calculated as below:-
sin B = 12/15 = 0.8
∠B = 53.1°
Therefore, the solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.

A. 45
B 4.50
C.40.50
D. 42
Answer:
C. $40.50
Step-by-step explanation:
OK so, If 20 articles cost ? 90, then the cost of 9 articles is ?
First you need to find out how much is 1 article.. Divide 90 by 20 you get, $4.5. now multiply 4.5 by 9. Which you get... 40.5. In other words it can also be written as, 40.50.
