in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC. calculate area of triangle ABC.​

Answers

Answer:

solution :

in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.

now ,

in rt angle tirangle ADC,

angleACD=45 degree, angle DAC=45 degree now,

in triangle ABD,

angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)

angle BAD+75+30=180

angle BAD=180-165      therefore,angle BAD=15

angle BAC =15+45=60

Area of triangle ABC=1/2×AB×AC×SIN 60

=1/2×10.2×14×√3/2

=61.83cm³ ans

simplify the following
√2×√18

Find the equation of the line.

Answers

To find the equation of the line, we need to figure out the slope and y-intercept.

To find the y-intercept, look at the number where the line intersects the y-axis. The number is 5. The equation so far is y = ?x + 5.

We still didn't figure out the slope yet. To figure out the slope, pick two points. Use the rise over run method. It is in the image below. The line is going up to the left, so the slope will be negative. Now we know the slope is -1/3. The equation now that we figured out the slope is y = -1/3x + 5.

I hope this helps you! Let me know if I got something wrong.

Answers

Answer: Choice D) 281.25 mg

================================================

Work Shown:

Plug in t = 2 and we get the following

[tex]a = 500*\left(\frac{3}{4}\right)^{t}\\\\a = 500*\left(\frac{3}{4}\right)^{2}\\\\a = 500*\left(0.75\right)^{2}\\\\a = 500*0.5625\\\\a = 281.25\\\\[/tex]

The answer is choice D. There are 281.25 mg of aspirin in the bloodstream after 2 hours.

-----------------

Side notes:

The 500 represents the initial amount of aspirin (in mg) in the bloodstream. This is the amount when t = 0.The 3/4 converts to 0.75; when solving 1+r = 0.75, we get r = -0.25, and this shows a 25% reduction in aspirin each time t goes up by 1. Every hour, the amount of aspirin in the bloodstream reduces by 25%

Answer:

375

Step-by-step explanation:

because if you look at the question 3\4 is 1 hour with the aspren 500 after 2 hours you 2 the ammount i think

The equation of the line that goes through (-3,5) and (2,-4)

Answers

Answer:

y=-9/5x-2/5

Step-by-step explanation:

Answer:

y=-9/5x-2/5

Step-by-step explanation:

Slope=m=Rise/Run=(y2-y1)/(x2-x1)=(-4-5)/(2-(-3))=(-9)/(5)=-9/5

So the equation becomes y=-9/5x+b

Plug in one of the given points:

y=-9/5x+b

-4=-9/5(2)+b

-4=-18/5+b

-0.4=b

b=-0.4

Therefore the equation of the line is y=-9/5x-2/5

what equation of a line passes through the points (0,8) and (6,4)

Answers

Answer:

y=-3/2x+6

Step-by-step explanation:

You will need to find the equation of the line in slope-intercept form y=mx+b.

First, find the slope m using slope formula m = (y_2-y_1)/(x_2-x_1) which is m=(6-(-6))/(0-8)=-12/8=-3/2

Now that you found the slope, your equation intercept form looks like y=-3/2 x+b.

Both points (8, -6) and (0.6) belong to this line, therefore both points coordinates satisfy line above which means: 6=-3/2(0)+b (i used second point here)

Solving for b we will get y intercept which is b=6

Finally, the line that passes through points (8,-6) and (0,6) has equation: y=-3/2 x + 6

Jane has 1 quarter, 3 dimes, and 4 nickels. What percent of dollar does Jane have?

i know the answer is 44% but can someone please explain how i got 44%??

Answers

Answer:

ok so I'm English not a hundred percent sure on your break down of money......so if I'm right in thinking that a nickel = 5 cents, dime = 10cents and a quarter =25cents

you add the amounts together

so 25 + 30 +20 = 75 cents.

there are 100 cents in a dollar so 100/100 X 75=75%

I have no idea how you got to 44%

In the last month, the ratio between Davis's monthly expenditure and his monthly salary was 3 : 7. What percentage of his monthly income did he save last month?

Answers

Answer: 57%

Step-by-step explanation:

Davis's monthly expenditure and his monthly salary was 3 : 7.

This means that for every $7 he received, he spent $3 out of it.

The amount he saved is therefore:

= 7 - 3

= $4

For every $7 received, he saved $4.

Percent = 4/7
