Answer:
1 5/6 miles
Step-by-step explanation:
first, we take the amout ethan lives from school, and turn it into a mixed number
2 5/12 = 29/12
marquis lived 7/12 mile closer
so, we have to subtract that from how far away ethan lives
29/12 - 7/12 = 22/12
22/12 simplified is 1 10/12 or 1 5/6
Two numbers are in the ratio 2:3. If 3 is added to the numbers, the ratio changes to 3:4. Find the numbers.
Answer:
6:9
Step-by-step explanation:
Answer:
6 and 9
Step-by-step explanation:
according to the question, the nos. are 2x and 3x.
then, (2x+3)/(3x+3)=3/4
therefore, 4(2x+3)=3(3x+3)
8x+12=9x+9
12-9=9x-8x
3=x
therefore the nos. are 2×3=6 & 3×3=9

What is the area in square units of trapezoid ABCD shown Below ?
Answer: Choice B) 50 square units
Work Shown:
A = h*(b1+b2)/2
A = 5*(12+8)/2
A = 5*(20)/2
A = 100/2
A = 50 square units (choice B)
Notice how the b1 and b2 are the parallel bases, while the height h = 5 is perpendicular to both of these bases.
The area of Trapezium ABCD is 50 square unit.
what is area of Trapezium?
The formula to calculate the area of trapezium is:
Area = ½ x Sum of parallel sides x Distance between the parallel sides
Given:
base 1= 8 , base 2 = 12 unit
height= 5 unit
so, the area of Trapezium
= 1/2 ( base 1 + base 2) /2
= 1/2 (8 + 12) x5
= 1/2 x 20 x 5
= 10 x 5
= 50 square unit.

Answer:
The decimal form of the equation is y = 2.5x + 10
The equivalent fraction form is y = (5/2)x + 10 because 5/2 = 2.5
===========================================================
Explanation:
We can pick any two columns from the table to form the two points needed.
I'll pick the first two columns
(1, 12.5)
(2, 15)
Then apply the slope formula to those points
m = (y2-y1)/(x2-x1)
m = (15-12.5)/(2-1)
m = (2.5)/(1)
m = 2.5
Now use that slope with either point mentioned to find the y intercept b.
y = mx+b
12.5 = 2.5*1 + b
12.5 = 2.5 + b
12.5 - 2.5 = b
10 = b
b = 10
Or
y = mx+b
15 = 2.5*2+b
15 = 5+b
15-5 = b
10 = b
b = 10
We end up with the same b value.
We found that m = 2.5 is the slope and b = 10 is the y intercept
Therefore we go from y = mx+b to y = 2.5x + 10
This is the same as saying y = (5/2)x + 10 since 2.5 = 5/2

5 A machine puts tar on a road at the rate of 4 metres in 5 minutes.
a) How long does it take to cover 1 km of road
b) How many metres of road does it cover in 8 hours?
Answer:
5 a) Total = 20.83 hrs = 20 hrs and 50 mins (1250mins total)
5 b) Total = 96 meters. = 0.096km in 8 hrs.
Step-by-step explanation:
1km = 1000 meters
5 mins = 4 meters
1000/4 = 250 multiplier
250 x 5mins = 1250 minutes
1250/60 = 20hrs + 50 minutes
50 / 60 = 0.83 = 20.83hrs
b) 8 hrs = 8 x 60 = 480 minutes
480/5 = 24 multiplier of 4 meters
24 x 4 = 96 meters

1. The negative leading coefficient (-2) tells you the parabola opens downward.

Step-by-step explanation:
Given,
the bigger triangle (∆GFH), <HGF = 90° and <GFH = 60° and GF = 4
In the 30-60-90 triangle, FH = 4×2 = 8
or you can find it like this,
cos60 = 4/FH
FH = 4/cos60 = 8
Now, I is the midpoint of FH, so, FI = 8/2 = 4
now for ∆FGI,
<GFI = 60°, GF = 4, FI = 4, it's a equilateral triangle, so we can say GI = 4
Now we need to find the height of ∆FGI, for that,
area of ∆FGI = (√3/4)×4² = 4√3 = 6.92820323..
So height (GJ) = 2×area/side = 2×4√3/4 = 2√3 = 3.46410162.. [height of ∆GFI (Because altitude is perpendicular distance from a point) = GJ, given]
now, in ∆GJI, GJ = 2√3, GI = 4 and <GJI = 90° (since itsy altitude, the angle will be a right angle, i.e. 90°)
So, JI = √{4²-(2√3)²} = 2
Area = 2×2√3/2 = 2√3 = 3.46410162.. = 3.46 (rounded to the nearest hundredth)

51/.04 = 1275
Answer:

4% x = 51
4/100 * x = 51 Multiply both sides by 100
100 * 4/100 * x = 5100

The count in a bacteria culture was 900 after 15 minutes and 1100 after 35 minutes. Assuming the count grows exponentially,
What was the initial size of the culture?
Answer:
300
Step-by-step explanation:
1100 = 900 [tex]e^{k*20}[/tex]
1.222222 = [tex]e^{k*20}[/tex]
ln(1.222) = 20k ln(e)
k = ln(1.222)/20
k = .2004
900 = x [tex]e^{15* .20004}[/tex]
900/x = [tex]e^{15* .20004}[/tex]
[tex]e^{15*.2004} = 900/x[/tex]
x = 900/ [tex]e^{15*.2004}[/tex]

Step-by-step explanation:
Two of the options (#1 and #4) can be ruled out immediately since they don't involve the difference of 26 and 10.
#3 can be ruled out because the difference needs to be multiplied by one fourth, but this option gives the wrong answer since the multiplication is done before subtraction (BODMAS)

Prove that y=x+2 is a tangent to the locous P(2t²,4t).
find the point of contact of this tangent to this locous and hence find the equation of normal at the point.
thanks
9514 1404 393
Answer:
tangent point: (2, 4)normal: y = -x +6Step-by-step explanation:
The derivative of P with respect to t is ...
P' = (x', y') = (4t, 4)
so the slope of the curve for some value of t is ...
dy/dx = y'/x' = 4/(4t) = 1/t
The line we want to be a tangent is y = x +2, which has a slope of 1. The curve will have a slope of 1 where ...
1/t = 1 ⇒ t = 1
At t=1, the point P is (2·1², 4·1) = (2, 4). For x=2, the point on the desired tangent is y = x +2 = 2 +2 = 4, or (x, y) = (2, 4).
The curve and the given line both have a slope of 1 at the point (2, 4), so that is the tangent point.
__
The normal to the curve at (2, 4) will have a slope that is the opposite reciprocal of the slope of the tangent: -1/1 = -1. Then point-slope form of the equation of the normal line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -4 = -1(x -2) . . . . . . line with slope -1 through point (2, 4)
y = -x +6 . . . . . . . . equation of the normal line in slope-intercept form
