Budget is total plan of income and expenditure of a period .

Here given that Her annual salary as a child care specialist is $14,700 after taxes. and she lives with her older sister and helps with the rent by paying $500 per month.

So money she have after rent can be calculated as:

[tex]14700-12\times500\\\\14700-6000\\\\=8700[/tex]

So her monthly saving after rent is

[tex]\frac{8700}{12} \\\\\\=725[/tex]

So her  monthly budget should be less than 725

Answer:

[tex]ML=27\\LN=27\\MN=54[/tex]

Step-by-step explanation:

Since L is the midpoint of MN, by the definition of midpoint:

[tex]ML=LN[/tex]

We can picture the following segment:

M----------L----------N

We know that [tex]ML=2x+7[/tex] and [tex]LN=3x-3[/tex]. Since the two segments are equivalent, we can set them equal to each other:

[tex]2x+7=3x-3[/tex]

Now, let's solve for x. Subtract -7 from both sides:

[tex]2x=3x-10[/tex]

Subtract 3x from both sides:

[tex]-x=-10[/tex]

Divide both sides by -1:

[tex]x=10[/tex]

So, the value of x is 10.

With this, we can find the remaining lengths.

We know that ML is [tex]2x+7[/tex].

Substitute 10 for x. So, the length of ML is:

[tex]ML=2(10)+7=20+7=27[/tex]

We know that LN is [tex]3x-3[/tex]. So, the length of LN is:

[tex]LN=3(10)-3=30-3=27[/tex]

Finally, MN will be the combined lengths of ML and LN. So:

[tex]MN=ML+LN=27+27=54[/tex]

And we're done!

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

Explanation:

An equilateral triangle has three sides of the same length, which in turn means that the curved arc pieces AB, BC and AC are the same length (but longer than each side of the triangle).

Furthermore, it leads to the fact that we split a 360 degree circle into three equal portions of 360/3 = 120 degrees each.

Imagine we drew in the line segments AX, BX, and CX. This splits the circle into 3 equal pie slices. Central angle BXC is 120 degrees because of the earlier calculation done before.

Answer:
12 adult tickets, 16 child tickets

Step-by-step explanation:

x is the amount of adult tickets
y is the amount of child tickets
----------------------------------------------------------

lets make 2 equations:
1)    x + y = 28
2)   8x + 5y = 176
----------------------------------------------------------

now we can substitute either x or y into the second equation so that we only have to deal with one variable at once.

x + y = 28
subtract y from each side:
x + y - y = 28 - y
which gives you:
x = 28 - y
-------------------------------------------------------

Then we plug that into the second equation, which will give us:

8(28 - y) + 5y = 176

now you want to expand 8(28 - y), so you use the distributive property.

8(28 - y) = 8*28 - 8*y = 224 - 8y

now that we have solved that, plug it back into the equation:

224 - 8y + 5y = 176

subtract 224 from each side:

224 - 8y + 5y - 224 = 176 -224

which gives us:
-3y = -48

now if you multiply each side by ( -1 ) you get:
3y = 48

now divide both sides by 3 and you get:
y = 48 / 3

48 / 3 is 16

y = 16
-------------------------------------------------------------------------------

now plug y = 16 into equation 1

equation 1 was x + y = 28

plug 16 in for y which gives us:

x + 16 = 28

subtract 16 from both sides

x + 16 - 16 = 28 - 16

Which finally gives us
x = 12
---------------------------------------------------------------------------------

Remember:
x is the amount of adult tickets
y is the amount of child tickets

x = 12 means that 12 adult tickets were sold
y = 16 means that 16 child tickets were sold

The expected frequencies from the data conducted to investigate the differences in the length of stay of a trip will be 221.7097, 72.471, 49.3881, and 25.7677.

From the complete question, the expected frequencies from the data about the trip will be calculated thus:

E(240) = (379 × 413) ÷ 706

=221.7097

E(83) =(379 × 153) ÷ 706

=72.471

E(40) = (379 × 92) ÷ 706

=49.3881

E(16) =(379 × 48) ÷ 706

=25.7677

Answer:

B. A(r(t)) = 25πt²

Step-by-step explanation:

Find the completed question below

The radius of a circular pond is increasing at a constant rate, which can be modeled by the function r(t) = 5t where t is time in months. The area of the pond is modeled by the function A(r) = πr². The area of the pond with respect to time can be modeled by the composition . Which function represents the area with respect to time? A. B. C. D.

Given

A(t) = πr²

r(t) = 5t

We are to evaluate the composite expression A(r(t))

A(r(t)) = A(5t)

To get A(5t), we will replace r in A(t) with 5t and simplify as shown

A(5t) = π(5t)²

A(5t) = π(25t²)

A(5t) = 25πt²

A(r(t)) = 25πt²

Hence the composite expression A(r(t)) is 25πt²

He walks 5/6 of a mile each day.

Multiply the distance each day by the number of days:

5/6 x 5

When multiplying a fraction by a whole number, multiply the numerator ( top number) by the whole number and leave the denominator ( bottom number as is)

5/6 x 5 = (5 x5)/6 = 25/6 now rewrite as a proper fraction:

25/6 = 4 1/6 total miles.

144 is the l.c.m of 16 and 18

explanation:

multiples:

16 - 16, 32, 48, 64, 80, 96, 112, 128, 144

18 - 18, 36, 54, 72, 90, 108, 126, 144

Therefore,  144 is the l.c.m of 16 and 18 which is divisible by both numbers.

Answer:

144

Step-by-step explanation:

First, prime factorize the numbers.

16 = 2⁴

18 = 3² x 2

LCM (16, 18) = 2⁴ x 3²

= 16 x 9

Answer:

294

Step-by-step explanation:

It is just 3x98

Step-by-step explanation:

I don't see all the options.

I only see the options under "angles", as it seems.

anyway, the way to prove this is :

the official definition of similar triangles is :

two triangles are said to be similar if their corresponding angles are congruent (and the corresponding sides are in proportion - but that is automatically true, when all 3 angles are matching).

so, if two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. we know this, because if two angle pairs are the same, then the third pair must also be equal (remember, the sum of all angles in a triangle is always 180°). When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

now, we look at the 2 triangles.

the angles QPR and STR are congruent (the same size).

we know also the angles QRP and SRT : they are both 90° and therefore congruent.

and that means that also the third angles PQR and RST are equal and therefore congruent (due to the 180° sum rule).

so, we have all 3 pairs of angles to be congruent, and the two triangles are therefore similar.

Answer:

(0, - 2)

Step-by-step explanation:

The y-intercept is the value of y when x = 0. Substitute 0 for x in the equation and solve for y.

[tex]2x - 3y = 6[/tex]

[tex]2(0) - 3y = 6[/tex]

[tex] - 3y = 6[/tex]

[tex] \frac{ - 3y}{ - 3} = \frac{6}{ - 3} [/tex]

[tex]y = - 2[/tex]

When x = 0, y = - 2.

Answer: Range is y > -1

Explanation:

The lowest point is where the open hole is. This is when y = -1. The open hole means we exclude it from the graph, so we can't reach y = -1

We can have any y value larger than -1 as part of the range. So the range is the set of y values such that y > -1

Side note: the domain is x > 1 for similar reasoning, but we're looking at the possible x values now.
