Based on the calculations, the measure of angle YUV is equal to 42°.
What is a line segment?A line segment refers to a part of a line that is bounded by two (2) distinct points and it has a fixed length.
Based on the information given, we can deduce the following:
O is center of circle (∠YUO = 90°)The measure of arc UV is 84° (∠UOV = 84°)OU is equal to OV and equal to radius (∠OVU = ∠OUV)From triangle UOV, we have:
∠OUV + ∠OUV + ∠UOV = 180°
2OUV + 84 = 180
2OUV = 180 - 84
2OUV = 96
OUV = 96/2
OUV = 48°
Now, we can determine the measure of angle YUV:
∠YUV = ∠YUO - ∠OUV
∠YUV = 90 - 48
∠YUV = 42°.

Jim's got profit percentage is 46.67%
What is profit percentage?Profit percentage is refer to "the amount of profit that has been incurred in terms of percentage".
According to the question,
Jim buys a wardrobe for £30 which is cost price of wardrobe and he sells £44.
In order to find profit percentage we have to use formula.
Profit percentage = [tex]\frac{selling price - cost price }{cost price}[/tex] × 100
= [tex]\frac{(44-30)}{30}[/tex] × 100
= [tex]\frac{14}{30}[/tex] × 100
= 46.6667% ≈ 47%
Hence, Jim's got profit percentage is 46.67%.

if 110% of a number is 528, then the number is:
a) 475.2
b) 52.8
c) 480
d) 580.8
e) 475
Answer:
c) 480
Step-by-step explanation:
Any percentage can be converted to a number ratio by dividing by 100%.
E.g. 100%/100% = 1
Following this concept, we can find the equivalent of 110% :
110%/100% = 1.1
Since 528 is 1.1 times the number we are looking for, we just need to divide 528 by 1.1 to find our number. This is because 1.1/1.1 = 1
528/1.1 = 480

Answer:Hello the Answer to your math problem is attached
Step-by-step explanation:
Identify the equations of ellipses whose major axis lengths are twice their minor axis lengths.
The equations of ellipses whose major axis lengths are twice their minor axis lengths are
(x - h)²/4b² + (y - k)²/b² = 1 and (x - h)²/b² + (y - k)²/4b² = 1To answer the question, we need to know what an ellipse is.
What is an ellipse?An ellipse is part of a conic section.
The equation of the ellipseThe equation of an ellipse centered at (h,k) with major axis on the x-axis and major axis length, 2a and minor axis length 2b is
(x - h)²/a² + (y - k)²/b = 1
The equation of ellipse with major axis x-axis
The equations of ellipses whose major axis lengths are twice their minor axis lengths with ellipse centered at (h,k) with major axis on the x-axis. Since the major axis is twice the length of the minor axis, a = 2b.
So, (x - h)²/a² + (y - k)²/b² = 1
(x - h)²/(2b)² + (y - k)²/b² = 1
(x - h)²/4b² + (y - k)²/b² = 1
The equation of ellipse with major axis y-axis
The equations of ellipses whose major axis lengths are twice their minor axis lengths with ellipse centered at (h,k) with major axis on the y-axis. Since the major axis is twice the length of the minor axis, a = 2b.
So, (x - h)²/b² + (y - k)²/a² = 1
(x - h)²/b² + (y - k)²/(2b)² = 1
(x - h)²/b² + (y - k)²/4b² = 1
So, the equations of ellipses whose major axis lengths are twice their minor axis lengths are
(x - h)²/4b² + (y - k)²/b² = 1 and (x - h)²/b² + (y - k)²/4b² = 1Learn more about ellipse here:

Is the point (2,-11) on the circle with radius 5 and center (2,13)?
Answer:
No
Step-by-step explanation:
Identify the equation for the circle
[tex](x-h)^2+(y-k)^2=r^2\\(x-2)^2+(y-13)^2=5^2\\(x-2)^2+(y-13)^2=25[/tex]
Check if (2,-11) is a point on the circle
[tex](x-2)^2+(y-13)^2=25\\(2-2)^2+(-11-13)^2=25\\0^2+(-24)^2=25\\576\neq25[/tex]
Since both sides of the equation are not equal to each other, then (2,-11) is not a point on the circle.

Answer:
x = 4
Step-by-step explanation:
x(x + 8) = 48
x² + 8x = 48
x² + 8x - 48 = 0
times into -48
add into 8
(x - 4)(x + 12) = 0
x - 4 = 0
x = 4
or
x + 12 = 0
x = -12

Enter the solution (x, y) to the system of equations shown.
Answer:
(2, 5 )
Step-by-step explanation:
y = 2x + 1 → (1)
3y = 4x + 7 → (2)
substitute y = 2x + 1 into (2)
3(2x + 1) = 4x + 7 ← distribute parenthesis on left side
6x + 3 = 4x + 7 ( subtract 4x from both sides )
2x + 3 = 7 ( subtract 3 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
substitute x = 2 into (1) for corresponding value of y
y = 2(2) + 1 = 4 + 1 = 5
solution is (2, 5 )

Step-by-step explanation:
Given equation:
[tex]3x^2-18x-21=0[/tex]
Factor to find the roots:
[tex]\implies 3(x^2-6x-7)=0[/tex]
[tex]\implies x^2-6x-7=0[/tex]
[tex]\implies x^2+x-7x-7=0[/tex]
[tex]\implies x(x+1)-7(x+1)=0[/tex]
[tex]\implies (x-7)(x+1)=0[/tex]
Therefore:
[tex]\implies (x-7)=0 \implies x=7[/tex]
[tex]\implies (x+1)=0 \implies x=-1[/tex]
Therefore, the roots of the quadratic equation are:
[tex]x = 7,\quad x = -1[/tex]
Let [tex]x_1 = 7[/tex]
Let [tex]x_2 = -1[/tex]

Determine the following probabilites based on a standard deck of cards

There are 52 cards total.
Hearts and diamonds are red.
Clubs and spades are black
LQ and K are called picture cards.
Answer & Step-by-step explanations:
I assume they want probability as a decimal as opposed to a fraction. I will do two questions for you, apply the same logic to all the rest.
P(Black or heart):
There are 26 black cards in a deck, and 13 (red) hearts.
26 + 13 out of 52 cards.
39 / 52 as a decimal is 0.75
P(Black or heart) = 0.75 or 75%
If wanted as a fraction, simplify your fraction down
39/52 has a common factor of 13, divide both numbers by 13
P(Black or heart) = 3/4
P(Red or 10):
There are 26 red cards and four 10's in a deck. Two of these 10's are red, so we will not double count them.
26 + 2 out of 52 cards.
28 / 52 as a decimal is about 0.54 or 54%
P(Red or 10) = 0.54 or 54%
If wanted as a fraction, simplify your fraction down
28/52 has a common factor of 4, divide both numbers by 4
P(Red or 10) = 7/13
