A rectangle is 4 miles longer than it is
wide. Find the dimensions of the
rectangle if its area is 221 sq-miles.
Answer:
1283 miklis
Step-by-step explanation:
Answer:
The lenght is 17 milesThe wide is 13 milesLet / l : the lenght of the rectangle
w : the wide of the rectangle
Step-by-step explanation:
[tex]a = l \times w \\ 221 = (w + 4) \times w \\ 221= w^{2} + 4w \\ {w}^{2} + 4w - 221 = 0 \\ (w + 17)(w - 13) = 0 \\ either \: w + 17 = 0 \\ so \: w = - 17 \: mile \: \: \: \: neglect \\ or \: w - 13 = 0 \\ so \: w = 13 \\ l = w + 4 \\ l = 13 + 4 = 17 \: mile[/tex]

What do the measures of angles BDA and BEA and the fact that AD and AE are radii of circle A tell us about BD and BE
Font Sizes
Answer:
BD and BE are tangents to the circle
Step-by-step explanation:
Given
See attachment
Required
What does BD and BE represent?
From the attachment, we have:
[tex]\angle BDA = 90^\circ[/tex]
[tex]\angle BEA = 90^\circ[/tex]
[tex]Radii = AD\ and\ AE[/tex]
The measure of angles between a tangent and the radius of a circle is always [tex]90^\circ\\[/tex]
So, because [tex]\angle BDA = 90^\circ[/tex] and AD is a radius, then BD is a tangent to circle.
Similarly,; [tex]\angle BEA = 90^\circ[/tex] and AE being a radius implies that BE is a tangent to circle.
Which equation represents a line that passes through (2, -0.5) and has a slope of 3? Oy - 2 = 3(x+ -0.5) 0 y 3= 2(x + 0.5) 0y + 7 = 3(x - 2) Oy + 7 + 2(x - 3)
Answer:
y=3x-6.5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-0.5)=3(x-2)
y+0.5=3x-6
y=3x-6-0.5
y=3x-6.5
The slope of a line indicates the measure of the steepness and the direction of the line. The slope of any line can be calculated using any two distinct points lying on the line. The equation is y = 3x-6.5. The correct option is D.
What is equation of a line?The equation of a line is an algebraic form which represents the set of points, which together form a line in a coordinate system. The equation of line is a linear equation with a degree of one. It can be formed with the help of the slope and a point on the line.
The equation of a line passing through the point and slope is given as:
(y - y₁) = m (x - x₁)
(y - -( 0.5)) = 3 ( x - 2)
(y + 0.5) = 3 (x - 2)
(y + 1/2) = 3 (x - 2)
or
y + 0.5 = 3x - 6
y = 3x - 6.5
Thus the correct option is D.

Your question is incomplete most probably your full question was:
Which equation represents a line that passes through (2, -0.5) and has a slope of 3?
A. y - 2 = 3( x + 1/2)

C. y + 1/2 = 3 (x - 2)
D. y + 1/2 = 2 (x -3)
A square has a diagonal that is 26 feet long.
What is the perimeter of this square?
answer:
52[tex]\sqrt{2}[/tex]
step-by-step explanation:
we can use the 45-45-90 triangle theorem for this: x, x, x[tex]\sqrt{2}[/tex]this is because this is a square
squares have two sides of the same length, and the diagonal is differentthe x's stand for the sides, whereas the x[tex]\sqrt{2}[/tex] stands for the diagonalx[tex]\sqrt{2}[/tex] = 26
x = 13[tex]\sqrt{2}[/tex]
now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 413[tex]\sqrt{2}[/tex] X 4 = 52[tex]\sqrt{2}[/tex]

The Johnson family pays 1,783 per month for rent. If the cost of their rent remains the same, how much will they pay for rent over 15 years?
Answer:
1 year= 12 months
1 months rent=1783
1783x12=21396
15 years = 180 months
the equation would be
1783x180=320940
or
21396x15= 320940

x^(2)-8x=-7
Please show work.
Answer:
This equation has two solutions.
1 solution is: x - 1
Solution #2 is : x - 7
Step-by-step explanation:
1. Move the constant to the left. We end up with x^2 - 8x +7 = 0
2. Rewrite the expression: x^2 - x - 7x + 7 = 0
3. Factor the expressions: x * (x-1) -7(x-1) = 0
4. Separate into possible cases : (x-1) * (x-7) = 0
5. Solve the equation(s): x-1 = 0
x-7 = 0
6. Possible solutions are as follows: x-1 OR x-7

How long will it take Eniola to save $5,000 if she started with $500 and found a rate of 6.2%? Round to the nearest whole number.
Answer:
the time period is 38.28 years
Step-by-step explanation:
The computation of the time period is shown below:
Given that
RATE = 6.2%
PV = $500
PMT = $0
FV = $5,000
The formula is shown below:
= NPER(RATE;PMT;-PV;FV;TYPE)
After applying the above formula, the time period is 38.28 years
Hence, in order to save $5,000 it would take 38.28 years

Step-by-step explanation:
[tex]SA=2(lw+lh+wh)[/tex] where l is the length, w is the width and h is the height
Plug in 42 as l, 35 as w and 64 as h
[tex]SA=2(42*35+42*64+35*64)\\SA=2(1470+2688+2240)\\SA=2(6398)\\SA=12796[/tex]
Therefore, the surface area of the figure is 12796 cm².
I hope this helps!
Answer:
Solution :-TSA = 2(lb + bh + lh)
TSA = 2(64 × 42 + 42 × 35 + 64 × 35)
TSA = 2(6398)
