Let the number of houses the boys deliver newspaper = x

Matthew delivers 2x newspapers

His brother delivers x newspapers,

Matthew earns per paper = $0.10

Matthew delivers twice a week so he earns = 0.10\times2=0.20

His brother earns per newspaper = $0.25

So, equation becomes,

0.20x+0.25x=13.95

0.45x=13.95

x=31

So, there are 31 houses where both these boys deliver newspapers.

Hence, Matthew delivers 2*31= 62 newspapers

His brother delivers 31 newspapers.

So, option A : Matthew: 62 papers; brother: 31 papers is the right option.

find the gradient of the line joining (3,7) and (6,9). Hence, find the acute angle it makes with the positive x-y axis​
stiv31 [10]

Answer:

33.7 degrees

Step-by-step explanation:

As we go from (3,7) to (6,9), x increases by 3 and y increases by 2.  Thus, the gradient (slope) of the line connecting these two points is

m = rise / run = 2/3.  Using the slope-intercept formula y = mx + b, we obtain

7 = (2/3)(3) + b, or 7 = 2 + b, so we see that b = 5 and y = (2/3)x + 5.  The y-intercept is (0, 5).

Next we find the x-intercept.  We set y = (2/3)x + 5 = to 0 and solve for x:

(2/3)x = -5, or (3/2)(2/3)x = -5(3/2), or x = -15/2, so that the x-intercept is

(-15/2, 0).  This line intersects the x-axis at (-15/2, 0).

Now look at the segment of this line connecting (-15/2, 0) and (0, 5).  Here x increases by 15/2 and y increases by 5, and so the tangent of the acute angle in question is

tan Ф = 5 / (15/2) = 10 / 15 = 2/3.

Using the inverse tangent function, we get Ф = arctan 2/3, or approx.

33.7 degrees.

I believe you meant "the acute angle it makes with the positive x-axis."​

. Harold works at a men's clothing store, which marks up its retail clothing by 27%. The store purchases pants for $74.00, suit
Paraphin [41]

Answer:

567.69

Step-by-step explanation:

Let p represent the original price

The Mark up is 27%

= 27/100

= 0.27

= p + 0.27p

= 1.27p

The retail price for pants is

= 1.27(74)

= 93.98

The retail price for suit jacket is

= 1.27(325)

= 412.75

The retail price for dress shirt is

= 1.27(48)

= 60.96

Therefore the markup for a pair of pants, dress shirts and suit jacket can be calculated as follows

= 93.98 + 412.75 + 60.96

= 567.69
