Answer:

-9+11x-8y

Step-by-step explanation:

Answer:

d = 48.03 feet

Step-by-step explanation:

Given that,

The maximum angle for a wheelchair ramp entering a business at 4.76 degrees.

We need to find the horizontal distance needed to accomidate a ramp that goes up to a door 4 feet of the ground.

We can solve it using trigonometry.

[tex]\tan\theta=\dfrac{h}{d}[/tex]

Where

h is height

d is the angle of elevation

[tex]d=\dfrac{h}{\tan\theta}\\\\d=\dfrac{4}{\tan(4.76)}\\\\d=48.03\ ft[/tex]

So, the horizontal distance is equal to 48.03 feet.

Answer:

the school

Step-by-step explanation:

the point given is (4,5) so let's try to hone in on that so to speak-

with that in mind, the way that i find the easiest to answer this is by using rise over run or the crawl before you walk method

seeing as how both are practically the same i'll just go with the craw before you walk method-

so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer

good luck :)

i hope this helps

Answer:

[tex]P' = (1,-2)[/tex]

Step-by-step explanation:

Given

[tex]P = (1.6)[/tex]

[tex]Q = (-6,1)[/tex]

Reflection over: [tex]y = 2[/tex]

Required

Determine the coordinates of P'

From the given coordinates, the y coordinates of P is 6 and the line of reflection is at y = 2

Since we are to reflect over y = 2, only the y coordinate of P will be affected.

The idea behind reflecting a point over a line is to have an equal distance between [the original point & the line of reflection] and [the new point & the line of reflection]

So, what to do is:

First, calculate the difference between the y coordinates of P and the line of reflection.

The y coordinate of P is 6 and the line of reflection is at y = 2.

So, the difference is: 6 -2 = 4

Next, subtract the calculated difference from the line of reflection to get the y coordinate of P'

y coordinate of P' = 2 - 4 = -2

Hence, the coordinate of P' is: (1,-2)

Answer:

i think it is A

Step-by-step explanation:

Answer:

A)  m = 1300 - 35(8)

Step-by-step explanation:

If your savings account has $1300 in it, and 35 is being taken away every month for 8 months, then you would multiple the months by the amount of money being taken away then subtract the amount from the total amount of money in her account. There for 'm = 1300 - 35(8)'.

Answer:

Cantidad de adultos= 975

Step-by-step explanation:

Dada la siguiente información:

Cantidad total de personas= 1.500

Proporición de niños y niñas= 0,35

Proporción de adultos= (1 - 0,35)= 0,65

Para calcular la cantidad de adultos, debemos utilizar la siguiente formula:

Cantidad de adultos= cantidad total de personas*proporción de adultos

Cantidad de adultos= 1.500*0,65

Cantidad de adultos= 975

Answer:

she invested 6600 at 3% and 3400 at 2.5%

Step-by-step explanation:

Simple interest = amount deposited x time x interest rate

Let the amount deposited in in the account bearing 3% interest by represented with a

Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)

a x 0.03 + (10,000 - a) x 0.025 = 283

0.03a + 250 - 0,025a = 283

collect like terms

0.03a - 0.025a = 283 - 250

0.005a = 33

a = 6600

the amount deposited in the 2.5% account = 1000 - 6600 = 3400

Answer: 57 R3

‎‎‎‎‎‎‎‎‎‎‎‎‎ ‎‎ ‎

Answer:

57 R 3

Step-by-step explanation:

6 goes into 34 5 times with 4 extra, pull down the 5, and 6 goes into 45 7 times with 3 extra. So the answer is 57 R 3.

Answer:

Step-by-step explanation:

The 75th percentile is the 3rd line, the median (50th percentile) is the second line, and the 25th percentile is the 1st line.

So, 10 is the answer.

Answer:

3 inch    6 inch  16 inch             3+6+16 = 25

Step-by-step explanation:

First piesce = F

Second piece = 2F

third piece = 5F+1

F + (2F) + (5F+1) = 25

8F +1 = 25

subtract 1 om both sides

8F = 24

divide both sides by 8

F= 3

3X2= 6

3X5 +1 = 16

Answer:

the percentage change on the drone is 42.86%

Step-by-step explanation:

The computation of the percentage change is shown below:

Since the helicopter was sold for $179.99

But amazon would be selling it for $125.99

So, the percentage change would be

= (Sale value -  sale value by amazon) ÷ ( sale value by amazon) × 100

= ($179.99 - $125.99) ÷ ($125.99) × 100

= 42.86%

Hence, the percentage change on the drone is 42.86%

Answer:

I'm not 100% sure, but I think the answer is 10 units squared.

Step-by-step explanation:

Find the area of each triangle, by multiplying each side, and dividing the answer in half. Add both of the triangles together, ending up as 6. Now we just find the area of the square. 2x2=4, add that to both of the triangles, and we're done. (2x2) ÷ 2 = 2 | (2x4) ÷ 2 = 4 | 2x2 = 4 | 4+4+2=10

Answer:

area=10 units^2

Step-by-step explanation:

[tex]a=\frac{(2+2+4)+(2)}{2} *2\\ =\frac{8+2}{2} *2\\ =\frac{10}{2} *2\\ =5*2\\ =10[/tex]

a=10 units^2

Answer:

C. 3n(6) + (6 – 2)

Step-by-step explanation:

C. 3n(6) + (6 – 2) has a coefficients, a product and a sum

Coefficients = 3

3 is the coefficients of n

Product means multiplication

3n(6) = product of 3n and 6

Sum means addition(+)

3n(6) + (6 – 2) = the addition of 3n(6) and (6 - 2)

3n(6) + (6 – 2)

= 18n + (4)

= 18n + 4

Answer:

the slope of the given line is m = rise / run = -1/2

Step-by-step explanation:

Going from (1, -1) to (3, -2), the 'rise' is actually a drop of 1 unit; the 'run' is +2.

Thus, the slope of the given line is m = rise / run = -1/2
