ladessa [460]

Answer:


Step-by-step explanation:

Well, this is a dumb problem... they're trying to trick you with the answers. :(

Okay, so what you're going to do is multiply the whole numbers by 1 put into the fractions.

Juan= 4 1/6--- 4 * 6/6 = 24/6

24/6 + 1/6 = 25/6


Antonio= 3 2/3 ---- 3 * 3/3 = 9/3

9/3 + 2/3 = 11/3


They changed the names around in the answers- Pay attention to who is associated to each fraction.


The right answer is D. Good luck... I hate it when problems try to trick you like that.

Please answer these 6 problems. Find the missing side to nearest tenth.

Since these are right triangles you can use the pythagorean theorem
a² + b² = c² 
a = one leg of the triangle
b = the other leg of the triangle
c = the hypotenuse

1. 4² + 3² = c²
   16 + 9 = c²
   25 = c²
  √25 = √c²
    5 = c
    c = 5cm

2. 5² + 12² = c²
    25 + 144 = c²
    169 = c²
    √169 = √c²
     13 = c
      c = 13in

4. 7² + 9² = c²
    49 + 81 = c²
    130 = c²
    √130 = √c²
    11.4 = c
    c = 11.4cm

5. a² + 10² = 15²
    a² + 100 = 225
    a² = 125
    √a² = √125
    a = 11.2ft

Daniel has $100. After he buys 4 pencils and 3 pens, he has $7 left. If each pencil costs $3 more than each pen, is $25 enough t
amm1812

Answer:  Yes, Daniel has enough money to buy 2 pens.

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

Explanation:

x = cost of one pencil

y = cost of one pen

4x = cost of 4 pencils

3y = cost of 3 pens

4x+3y = cost of 4 pencils and 3 pens

100 - (4x+3y) = amount Daniel has left = 7 dollars

100-(4x+3y) = 7 is one equation we can form

Another equation we can form is x = y+3 because "each pencil costs $3 more than each pen".

Let's plug that into the first equation and solve for y.

100-(4x+3y) = 7

100-(4(y+3)+3y) = 7

100 - (4y+12+3y) = 7

100 - (7y+12) = 7

100 - 7y - 12 = 7

-7y + 88 = 7

-7y = 7-88

-7y = -81

y = -81/(-7)

y = 11.57 is the cost of one pen

2y = 2*11.57 = 23.14 is the cost of two pens.

Since this is less than $25, this means he has enough to buy two pens. This assumes that we either ignore tax, or the tax is already included in the listed prices.

The functions f(x) = (x + 1)2 - 5 and g(x) = -(x - 2)2 + 3 have been rewritten using the completing-the-square method. What is t
emmasim [6.3K]

f(x) has vertex = (- 1, - 5 ) and is a minimum

g(x) has vertex = (2, 3 ) and is a maximum

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = (x + 1)² - 5 is in this form with vertex = (- 1, - 5 ) and minimum

to determine if maximum/ minimum

• if a > 0 then minimum

• if a < 0 then maximum

g(x) = - (x - 2)² + 3 is also in vertex form with a < 0

vertex = (2, 3 ) and is a maximum
