Write your answers in simplest form.

Answer:

Work backward.  If at the end they both had 12 cents.  Then Betty had to have given Ann 6 cents.  Which means that Betty had to have had 18 cents, because there is always a total of 24 cents.  Which meant that before that, Betty had 9 and was given 9 cents.  So Betty originally had 9 cents.  So Ann had 24 minus 9 or 15 cents at the beginning.

Answer:

x = 9.9

Step-by-step explanation:

This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.

In this case, multiply. The side measurement of 1 has 7.

1 x 7 = 7

In the same, you must multiply 7 with √2

x = 7 * √2 = 7√2.

√2 = ~1.414

7 x 1.414 = 9.898

Round to the nearest tenth:

9.898 rounded to the nearest tenth = 9.9

x = 9.9

~

Answer:

9.9 is your answer

Step-by-step explanation:

by using Pythagoras law

p²+b²=h²

7²+7²=x²

x=√{2×49)=7√2or 9.9 is your answer

Answer:

Step-by-step explanation:

Answer:

38/3 yards

Step-by-step explanation:

Given that,

Fabric required to make a shirt = 2/3 of a yard

Fabric required to make a skirt = 12 yards

Total fabric needed,

[tex]x=\dfrac{2}{3}+12\\\\=\dfrac{38}{3}\ yards[/tex]

Hence, 38/3 yards of fabric is needed.

Answer:

The amount is 5,955.08

Step-by-step explanation:

Here, we want to calculate compound interest

We can find this by using the compound interest formula

A = P( 1 + r/n)^nt

A is amount

P

is the principal = 5,000

r is the interest rate = 6% = 6/100 = 0.06

n is the number of times per year in which the interest is compounded = 1

t is the number of years = 3

Substituting these values;

A = 5,000(1 + 0.06/1)^3(1)

A = 5000(1.06)^3

A = 5,955.08

Answer:

u=1/2

Step-by-step explanation:

if v=-1 then v is multiplying u, -u+ -u which gives -2u. to find u, divide both sides by -2 .-1/-2 the negative cancels the negative giving you positive number, which is 1/2

Answer:

3 3/4 inches = 562.5 miles

Step-by-step explanation:

Given that,

1/2 inch = 75 miles

It means,

1 inch = (75×2) miles

= 150 miles

3 3/4 inches= 15/4 inches

So,

[tex]\dfrac{15}{4}\ \text{inches}=\dfrac{15}{4}\times 150\\\\=562.5\ \text{miles}[/tex]

Hence, 3 3/4 inches is equal to 562.5 miles.

Answer:

(i) The axis of symmetry is [tex]x = -4[/tex].

(ii) The axis of symmetry is [tex]x = 4[/tex].

(iii) The axis of symmetry is [tex]x = 1[/tex].

Step-by-step explanation:

We proceed to explain how we determine the expression for the axis of symmetry for each case:

(i) [tex]f(x) = 3\cdot (x+4)^{2}+1[/tex]

The expression depicts a vertical parabola, meaning that axis of symmetry is vertical, that is, a function of the form [tex]x = a,\,\forall\,a\in \mathbb{R}[/tex]. This line passes through the vertex of the parabola. The component [tex]x+4[/tex] contains the information of the horizontal component of the vertex, where the axis passes through. Therefore, the axis of symmetry is [tex]x = -4[/tex].

(ii) [tex]f(x) = 2\cdot x^{2} -16\cdot x +15[/tex]

At first we complete the square and factor the perfect square trinomial:

[tex]f(x) = 2\cdot \left(x^{2}-8\cdot x +\frac{15}{2} \right)[/tex]

[tex]f(x) = 2\cdot \left[(x^{2}-8\cdot x +16) +\frac{15}{2}-16 \right][/tex]

[tex]f(x) = 2\cdot (x-4)^{2}-17[/tex]

By applying the approach used in (i), we find that the axis of symmetry is [tex]x = 4[/tex].

(iii) First, we locate the vertex of the parabola, which is (1,-3). The first component of the ordered pair contains all the needed information to determine the equation of the axis of symmetry, which is [tex]x = 1[/tex].
