Help pls!! Find the value of x and the perimeter of rhombus ABDC
Answers
Answer:
it is the first one
Step-by-step explanation:
Answer:
x = 7
Perimeter = 44
Step-by-step explanation:
All 4 sides of a rhombus are congruent so their lengths are equal.
Therefore, 2x - 3 = x + 4 or x = 7
The length of the side x + 4 = 11
The perimeter is 4 x 11 = 44
A circle with radius of 2 cm sits inside a 11 cm x12 cm rectangle What is the area of the shaded region?
Answers
Answer:
119.4 cm^2
Step-by-step explanation:
Area of a circle is [tex]\pi[/tex] x radius^2, and the area of a rectangle is length * width. 11 cm x 12 cm = 132 cm^2 (rectangle's area). The circle's area would be [tex]\pi[/tex] x 2^2 which would equal 12.56637061 cm^2 (left unrounded until the end). Then subtract 12.56637061 from 132 cm^2 and that would equal 119.4 cm^2 rounded to the tenth.

question: solve the solution using substitution.
Answers
Answer:
x = -3
y = -8
Step-by-step explanation:
2y = x - 13
3x = y - 1; let y = 3x + 1
substitute to solve for 'x':
2(3x + 1) = x - 13
6x + 2 = x - 13
5x + 2 = -13
5x = -15
x = -3
solve for 'y':
3(-3) = y - 1
-9 = y - 1
-8 = y
Answer:
(-3,-8)
Step-by-step explanation:
Get one of the variables by themself.
3x = y-1
y = 3x+1
Plug that equation into the other one
2(3x+1) = x-13
Distribute the 2 to 3x+1
6x+2 = x-13
Combine like terms
6x+2 = x-13
-x -x
5x+2 = x-13
-2 -2
5x = -15
Divide by 5 on both sides
5x = -15
÷5 ÷5
x = -3
Find y
3(-3) = y-1
-9 = y-1
+1 +1
y = -8

£747 in the ratio 2:7
Answers
Answer:
£166 : £581
Step-by-step explanation:
sum the parts of the ratio, 2 + 7 = 9 parts
Divide the amount by 9 to find the value of one part of the ratio
£747 ÷ 9 = £83 ← value of 1 part of the ratio, then
2 parts = 2 × £83 = £166
7 parts = 7 × £83 = £581
£747 = £166 : £581 in the ratio 2 : 7
Which equation represents a parabola with the focus at (0, -1) and
the directrix y
= 1?
(1) x2 = -8y
(3) x2 = Sy
(2) x2 = - 4y
(4) x2 = 4y
Answers
Answer:
Step-by-step explanation:
The vertex is halfway between focus and directrix, at (0,0).
The equation has the form y = ax².
Focal length p = distance between focus and vertex = 1
p = 1/|4a|
1 = 1/|4a|
|a| = ¼
The focus lies below the vertex, so the parabola opens downwards and a<0.
y = -¼x²
Equation represents a parabola with the focus at (0, -1) and
the directrix y=1 is [tex]x^2=-4y[/tex]
Given :
a parabola with the focus at (0, -1) and the directrix y= 1
The standard equation of parabola is [tex]y-k=\frac{1}{4p} (x-h)^2[/tex]
Focus is at (0,-1)
The midpoint of focus and directrix is the vertex
Directrix is at y=1
Midpoint of (0,-1) and y=1 is (0,0)
So the vertex is (0,0) that is our (h,k)
Now we find the value of p
The distance between vertex (0,0) and focus (0,-1) is the value of p
focus and vertex are 1 unit away. So p=-1
we got h=0 and k=0 and p=-1
Replace all the value in the standard equation
[tex]y-0=\frac{1}{4(-1)} (x-0)^2\\y=\frac{-1}{4} x^2\\4y=-x^2\\x^2=-4y[/tex]
Equation represents a parabola with the focus at (0, -1) and
the directrix y=1 is [tex]x^2=-4y[/tex]

Given right triangle ABC with altitude BD drawn from vertex B to hypotenuse AC, find the lengths of AD, BD, and CD.
Keep as improper fraction
Answers
Answer:
AD = 3
BD = 10
CD = 17
Step-by-step explanation:
The requires side lengths are:
[tex]AD = \frac{49}{25}[/tex]
[tex]BD = \frac{168}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]
Considering triangle BDC, we have:
[tex]BC^2 = BD^2 +CD^2[/tex]
This gives
[tex]24^2 = BD^2 +(25 - AD)^2[/tex]
[tex]576 = BD^2 +(25 - AD)^2[/tex] --------- (1)
Considering triangle ABD, we have:
[tex]7^2 = BD^2 + AD^2[/tex]
[tex]49 = BD^2 + AD^2[/tex] ---- (2)
Subtract (2) from (1)
[tex]576 - 49 = BD^2 -BD^2 +(25 - AD)^2 - AD^2[/tex]
[tex]527 = (25 - AD)^2 - AD^2[/tex]
Expand
[tex]527 = 625 - 50AD + AD^2 - AD^2[/tex]
[tex]527 = 625 - 50AD[/tex]
Collect like terms
[tex]50AD = 625 - 527[/tex]
[tex]50AD = 98[/tex]
Divide both sides by 50
[tex]AD = \frac{98}{50}[/tex]
Reduce fraction
[tex]AD = \frac{49}{25}[/tex]
Recall that:
[tex]49 = BD^2 + AD^2[/tex]
So, we have:
[tex]49 = BD^2 + (49/25)^2[/tex]
[tex]49 = BD^2 + 2401/625[/tex]
Collect like terms
[tex]BD^2 = 49 - 2401/625[/tex]
Take LCM
[tex]BD^2 = \frac{625 *49 - 2401}{625 }[/tex]
[tex]BD^2 = \frac{28224}{625}[/tex]
Take the square roots of both sides
[tex]BD = \frac{168}{25}[/tex]
Also, we have:
[tex]CD = 25 - AD[/tex]
This gives
[tex]CD = 25 - \frac{49}{25}[/tex]
Take LCM
[tex]CD = \frac{625 - 49}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]
Hence, the requires side lengths are:
[tex]AD = \frac{49}{25}[/tex]
[tex]BD = \frac{168}{25}[/tex]
[tex]CD = \frac{576}{25}[/tex]

Answers
Answer:
x ≈ 7.7
Step-by-step explanation:
Using Pythagoras' identity on the right triangle on the right side
let the third side be y , then
y² + 4² = 10²
y² + 16 = 100 ( subtract 16 from both sides )
y² = 84
Using Pythagoras' identity on the right triangle on the left side
x² + 5² = y²
x² + 25 = 84 ( subtract 25 from both sides )
x² = 59 ( take the square root of both sides )
x = [tex]\sqrt{59}[/tex] ≈ 7.7 ( to the nearest tenth )
