pls help with this math question !
thx !

Cost of a bike Raylin wants to buy = $85

Money Raylin already has = $22

Money she needs :

[tex] = \tt85 - 22[/tex]

[tex] = \tt\$63[/tex]

Thus, money Raylin still needs = $63

Money she gets from doing one chore = 2.50

Number of chores the needs to do :

[tex] = \tt \frac{63}{2.50} [/tex]

[tex]\color{plum} =\tt 25 \: chores[/tex]

Thus, Raylin needs to do 25 chores to be able to buy the bike.

Therefore, the correct option is (d) 25

Answer:

[tex]A' = (0,0)[/tex]

[tex]B'= (9,18)[/tex]

[tex]C'= (21,12)[/tex]

Step-by-step explanation:

Given

[tex]A= (0,0)[/tex]

[tex]B= (3,6)[/tex]

[tex]C= (7,4)[/tex]

[tex]k = 3[/tex] -- dilation factor

Required

Determine the coordinates of the new triangle

This is calculated using:

[tex]New = Old * k[/tex]

So, we have:

[tex]A' = A *3[/tex]

[tex]A' = (0,0) *3[/tex]

[tex]A' = (0,0)[/tex]

[tex]B' = B * 3[/tex]

[tex]B'= (3,6)*3[/tex]

[tex]B'= (3*3,6*3)[/tex]

[tex]B'= (9,18)[/tex]

and

[tex]C' = C * 3[/tex]

[tex]C'= (7,4)*3[/tex]

[tex]C'= (7*3,4*3)[/tex]

[tex]C'= (21,12)[/tex]

Step-by-step explanation:

Los movimientos bancarios de Santiago se representan matemáticamente teniendo en cuenta que consignar es sumar y retirar el restar. Por lo tanto podes expresar los movimientos bancarios de la siguiente manera:

Al realizar la sumatoria se obtiene:

 +300.000 - 120.000 - 95.000 + 80.000 = + 165.000

En la semana Santiago obtiene en su cuenta bancaria $165.000

Answer:

sec A = 5/4

Step-by-step explanation:

Sec of an angle is hypotenuse/adjacent side

In your problem, sec A = 25/20 = 5/4

It helps if you can draw a figure of the problem.  Make sure you memorize the definition of each trig function

Answer:

1/9

Step-by-step explanation:

if your question is about evaluting f^-2

then the answer is

f = 3

then

f^-2 = 3^-2 = 1/9

Answer:

3

Step-by-step explanation:

You meant f^-2(g) for f = 3 and g = 27.

(3^-2)(27)

= 1/9(27)

= 3

:)

Answer:47

Step-by-step explanation:

Make a hypothesis that the number is X, so X-14=20+13

X=20+13+14, eventually, you'll get that X=47

But I'm not sure if you mean 13 times more than 20, or just 13 more than 20

Step-by-step explanation:

let the ratio be x

now,

3x+5x+9x+13x=360°(sum of angle of quadrilateral is 360°)

30x=360°

x=360/30

x=12°

then,

3x=3×12=36°

5x=5×12=60°

9x=9×12=108°

13x=13×12=156°

so,the angles of quadrilateral are 36°,60°,108°& 156°

Answer:

the ratio of wheat cereal to rice cereal is 1:6 and the value is 1/6 or 0.16666

Step-by-step explanation:

if 1 1/2 = 1/4 then ?=4/4

since we know the value of 1/4 we multiply 1 1/2x4=6 and 1/4x4=1 so the ratio is 1:6. The value of the ratio is the quotient, and the quotient of 1 and 6 is 1/6 or 0.16666

hope this helps sorry if im wrong and have a blessed day :)

Step-by-step explanation:  1 will now become a 2, so the answer is 1.2.1,

Answer:

so C but might be A

Step-by-step explanation:

Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

good luck, i hope this helps :)

Answer:

Simple, Her Pentagon is not straight

Step-by-step explanation:

Carla's Pentagon is not straight. Her symmetry line is off scale. Simply fix the Line on the pentagon And it will be correct.

Hope this helps ^

We have that the correct Pentagon should have

Symmetry

This can be defined as an exact correspondence between different part of a system .

Therefore it can be said that Carla's Pentagon lacks Symmetry

Where a

Answer:

c. (-1, -2)

Step-by-step explanation:

The solution is the point of intersection of the lines.

Read that point off the graph.

Start from the point where the x-axis and the y-axis intersect. Go left 1 unit. That is x = -1. Now go down 2 units. That is y = -2. The point that has x-coordinate -1 and y-coordinate -2 is the point (-1, -2). That is the solution.

The point is (-1, -2).

Answer: C. (-1, -2)

Answer:

x-intercept:   -5/2

y-intercept:   15/4

Step-by-step explanation:

to find x-intercept set y = 0

-6x + 4(0) = 15

-6x = 15

x = -15/6

x = -5/2

to find y-intercept set x = 0

-6(0) + 4y = 15

4y = 15

y = 15/4

Answer:

y-intercept is -2.5 and x-intercept is 3.75
