Segment bc is parallel to De. Use the proportion from a B to BD to find the missing length of CE

Mathematics

Alla [95]2 years ago
4 0

Answer:

CE = 6

Step-by-step explanation:

we use the proportion relationship:

\frac{AB}{BD} = \frac{AC}{CE\\}\\then

\frac{2}{3} = \frac{4}{CE}\\\\then

2×CE = 3 ×4 (cross multiply)

then

2×CE = 12

then

CE = 12/2 = 6

astra-53 [7]

Answer: +$45

Step-by-step explanation: if his actual pay for the week was $100 then from the question he incorrectly calculated it as {$100 + $45} = $145 which is $45 above his actual pay.

Error = measured value - actual

value.

= $145 -$100 =$45.

NOTE: since the value he assumed{$145} is greater than his actual pay{$100}, we have to include a positive sign to the error{$45}.

Therefore, Error = +$45.

A uniform border on a framed photograph has the same area as the photograph. What are the outside dimensions of the border if th
Black_prince [1.1K]

Given dimension of photograph = 25cm * 20cm

So area of photograph = 500cm²

Now, let the width of frame border be = x

So, dimensions of photograph + frame= (25 + 2x)*(20 + 2x)

As given, the area of frame is same as photograph , so

Area of picture + frame = 1000cm  ²

Hence, area equals

4x^{2}+90x+500=1000

4x^{2}+90x-500=0

2x^{2}+45x-250=0

Solving this quadratic equation,

For the quadratic equation of the form ax^{2}+bx+c=0 , solution is:

x1,2 = \frac{-b+\sqrt{b^{2}-4ac}}{2a}

Now putting a=2, b=45, c= -250 and solving he above equation, we get two values of x.

x = -27.11 (discard it as it is negative)   and

x = 4.61 cm

Hence the dimensions of the frame are:

20+2x = 20+2(4.61) = 29.22 cm

25+2x = 25+2(4.61) = 34.22 cm

What function represents a line with a slope of -4 and a y-intercept of -2?
lubasha [3.4K]

Answer:

y=-4x-2

Step-by-step explanation:

the slope intercept form of an equation is y=mx+b, where m is the slope and b is the y intercept. plugging in -4 as the slope, m and -2 as the y-intercept, b, we get the equation y=-4x-2
