Answer:
[tex]area = 960cm^2[/tex]
Step-by-step explanation:
Perimeter = 2 x (length + width) ------(1)
Perimeter = 124cm
Let length be x
Given width is 2cm shorter than length , that width = x -2
[tex]Perimeter = 2 (x + (x -2))\\\\124 = 2(x +x -2)\\\\62 = 2x -2 \\64 = 2x\\x = 32[/tex]
Length = 32cm
Width = 32 - 2 = 30cm
Area = length x width
[tex]= 32 \times 30 = 960cm^2[/tex]
its me arg i need help
Answer:
x=8
Step-by-step explanation:
so since the whole thing should equal 180, and the right triangle is 90,
(3x+11)+(5x+15)=90 then solve for that
8x+26=90
8x=64
divide both sides by 8
so x=8
then plug in 8 for the xs so c is 3(8)+11 --> 24+11 so m<C=35*
m<D=90*
5(8)+15 40+15 so m<E=55
4 out of 5 phones that are recycled, have cracks on the screens. If 30 phones got recycled today, how many probably had cracks on their screens?
Answer:
24
Step-by-step explanation:
The unit rate of 4:5 is 0.8 because 4 divided by 5 is 0.8
0..8 x 30= 24
find the value of x, if the slope of the line joining (4,3) and (x,5) is 2/3?
Answer:
Step-by-step explanation:
here,x1=4,y1=3,x2=x and y2=5
slope=2/3
use formula
slope=y2-y1/x2-x1
2/3=5-3/x-4
2/3=2/x-4(do cross multiplication)
2(x-4)=3*2
2x-8=6
2x=6+8
x=14/2
x=7

Solve for x.
5x+2y=13
x+2y=9
Answer:
x = 1
y =
5x + 2y = 13
x + 2y = 9
Add both equations.
6x + 4y = 22
Solve for x.
6x = 22 - 4y
x = 22/6 - 4/6y
step-by-step explanation:
Put x as 22/6 - 4/6y in the second equation and solve for y.
22/6 - 4/6y + 2y = 9
-4/6y + 2y = 9 - 22/6
4/3y = 16/3
y = 16/3 × 3/4
y = 48/12
y = 4
Put y as 4 in the first equation and solve for x.
5x + 2(4) = 13
5x + 8 = 13
5x = 13 - 8
5x = 5
x = 5/5
x = 1

Answer: Line 4
Step-by-step explanation: The slope of this line is angled downward. The others are either angled upward or straight up. The vertical and horizontal lines have 0 in their slopes. So, line 4 is the only line with a negative slope because it has a negative number in the slope. ((x,y), y would be negative.)
Answer:
Hi, there your answer will D.4

On the Unit Circle:
If cos x < 0 which Quadrant(s) is the angle?
1. I &IV
2. II & III
3. I &II
4. III & IV
Answer:
Quadrant I and quadrant IV
Step-by-step explanation:
Given that cos x< 0
x < arccos 0
x < 90degres
Since cos s positive in the first and 4th quadrant, hence the angle lies in the Quadrant I and quadrant IV

How do I find the measure qrs help????
I’m very confused thanks guys
Answer:
I do not know good luck my bro
Step-by-step explanation:
Answer:
∠QRS = 72°
Step-by-step explanation:
∠R + ∠Q = 180° (supplementary angles)
18x + 12x = 180
30x = 180
x = 6
∠R = 12x = 72° ∠Q = 18x = 108°
Nina operate the dog walking service she charges a flat fee for $15 plus $5 per hour. which equation represents this liner relationship.
y= 15x - 5
y= 15x + 5
y= 5x - 15
y= 5x + 15
Answer: I think it’s the first one
Step-by-step explanation:
It says per hour and 15 bucks plus 5 bucks PERhour so you would have to be multiplying I did a question like this long ago hope you get it right
The equation represents this linear relationship for total cost is y= 5x + 15 thus option (D) is correct.
What is a linear function?A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given,
She charges a flat fee of $15 plus $5 per hour.
For x number of hours, the total cost will be as,
y = 15 + 5x
Hence "y= 5x + 15 is the equation that depicts this linear relationship for total cost".

Find the volume of the frustrum of the right circular cone generated by rotating the line y = 3x+1 about the x-axis between x = 0 and x = 2.
Answer:
38π cubic units
Step-by-step explanation:
The volume V = ∫₀²πy²dx
Since y = 3x + 1, dy = 3dx ⇒ dx = dy/3
So, when x = 0, y = 3(0) + 1 = 0 + 1 = 1
when x = 2, y = 3(2) + 1 = 6 + 1 = 7
So, changing the variable to y and the limits of integration from y = 1 to y = 7, we have
V = ∫₀²πy²dx
V = π∫₁⁷y²dy/3
V = π[y³/3]₁⁷/3
V = π[y³]₁⁷/9
V = [7³ - 1³]π/9
V = [343 - 1]π/9
V = 342π/9
V = 38π cubic units

Two triangular prisms with the same altitude always have the same surface
area.
A. True
B. False
The prisms might have different base areas, which would contribute to overall having different surface areas even if the altitude (aka height) of each prism was the same.

=======================================================
Explanation:
Let x be the angle measure of that dark area. That angle x must add to the other angles 25, 90, and 25 to get a full 360 degree rotation.
So,
x+25+90+25 = 360
x+140 = 360
x = 360-140
x = 220
The dark area angle is 220 degrees
This is known as a reflex angle due to it being larger than 180 degrees, but it's less than 360 degrees. In symbolic terms, any reflex angle is one such that 180 < x < 360.

explain why n(n-1) must be an even number
n & n - 1 are two consecutive numbers which means one of is surely even and the other one is odd.
_______________________________
Suppose that n is an even number;
So we can right n like this :
n = 2t
Thus :
n - 1 = 2t - 1
_______________________________
n( n - 1 ) = 2t( 2t - 1 ) = 2 ( 2t^2 - t )
= 2 ( q ) = 2q
The number obtained is a multiple of 2, so it is definitely even because all numbers are even multiples of 2.

System of Equations Problem.
Solve v(7)+b(6)=394;v(3)+b(12)=612
Solve 6b+7v=394 for b
Add -7v to both sides.
6b+7v+−7v=394+−7v
6b=−7v+394
Divide both sides by 6.
[tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex]
Substitute [tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex] for b in 12b+3v=612
12b+3v=612
[tex]12(\frac{-7}{6} v+\frac{197}{3} )+3v=612[/tex]
Simplify both sides of the equation.
−11v+788=612
Add -788 to both sides.
−11v+788+−788=612+−788
−11v=−176
[tex]\frac{-11v}{-11} =\frac{-176}{-11}[/tex]
v=16
Substitute 16 for v in [tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex]
[tex]b=\frac{-7}{6} v+\frac{197}{3}[/tex]
[tex]b=\frac{-7}{6}(16)+\frac{197}{3}[/tex]
Simplify both sides of the equation.
b=47
Answer:
b=47 and v=16
