The length of a rectangle is 16 cm less than quadruple the width. If the perimeter is 28 cm,
what is the length and the width?

Answer:

$30.48

Step-by-step explanation:

Meals tax = 25.30 x 1.06

= 26.50

Tip = 1.15 x 26.50

= 30.475

after rounding = $30.48

The meal cost $30.48 in total.

Answer:

a) i) y = - 5/3

  ii) y = 4/3

b) i) x = 1

   ii) x = -3/4

Step-by-step explanation:

[tex]y=\dfrac23x +\dfrac13[/tex]

a) i) [tex]x=-3[/tex]

[tex]\implies y=\dfrac23(-3) +\dfrac13\\\\\\\implies y=\dfrac{-6}{3} +\dfrac13\\\\\\\implies y=\dfrac{1-6}{3} \\\\\\\implies y=-\dfrac53[/tex]

ii) [tex]x=1\frac12=\dfrac32[/tex]

[tex]\implies y=\dfrac23\left(\dfrac32\right) +\dfrac13\\\\\\\implies y=\dfrac{6}{6}+\dfrac13\\\\\\\implies y=\dfrac{3}{3}+\dfrac13\\\\\\\implies y=\dfrac{3+1}{3}\\\\\\\implies y=\dfrac43[/tex]

b) i) [tex]y=1[/tex]

[tex]\implies \dfrac23x +\dfrac13=1\\\\\\\implies \dfrac23x =1-\dfrac13\\\\\\\implies \dfrac23x =\dfrac23\\\\\\\implies x =1[/tex]

ii) [tex]y=-\dfrac16[/tex]

[tex]\implies \dfrac23x +\dfrac13=-\dfrac16\\\\\\\implies \dfrac23x =-\dfrac12\\\\\\\implies x =-\dfrac12 \div \dfrac23=-\dfrac12 \times\dfrac32=-\dfrac34[/tex]

Figure A, B, D have point symmetry.

Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction. It looks the same when viewed from opposite directions (180° rotation).

Try imagining how each of the figure will look after rotating it for 180°.  If it looks exactly same as the original figure, it has point symmetry.

x = 7

Step-by-step explanation:

5x - 1 + 8x + 5 = 95

13x + 4 = 95

13x = 91

x = 7

Triangle in 95° so x is

»8x + 5° + 5x - 1° = 95°

Step-by-step explanation:

In the given arithmetic series,

To find the sum of the series, we need to find the number of terms (n) at first. So,

[tex]a_{n} = a + (n - 1)d\\38 = 6 + (n - 1) 4\\38 - 6 = 4n - 4\\32 = 4n - 4\\32 + 4 = 4n\\36 = 4n\\36 \div 4 = n\\\boxed{9 = n}[/tex]

Now, let's find the sum of the arithmetic series (Sₙ).

[tex]S_{n} = \frac{n}{2} [2a + (n - 1)d]\\S_{n} = \frac{9}{2} [2*6 + (9 -1)4]\\S_{n} = \frac{9}{2} [12+ (8*4)]\\S_{n} = \frac{9}{2} [12+ 32]\\S_{n} = \frac{9}{2} (44)\\S_{n} = 9*22\\\boxed{S_{n} = 198}[/tex]

Answer:

First, let's just pick an arbitrary number as an example 7.031.

the 1 is in the thousandth place, so we can represent this as [tex]7\frac{31}{1000}[/tex].

This is so because determining what denominator of a decimal number is can be known through what non-zero digits is on the right-most side of the number.

Step-by-step explanation:

Answer:

The third digit after a decimal point is in the "thousandth" place.

Therefore, to convert a decimal that terminates after three decimal places to a fraction, simply write the digits (without leading zeros) as the numerator and 1000 as the denominator.

For example:

[tex]12.345=\dfrac{12345}{1000}[/tex]

[tex]0.932=\dfrac{932}{1000}[/tex]

Answer:

A. x = 212

Step-by-step explanation:

      This scale is showing us that x + 122 is equal to 334 because the scale is balanced and we can see an equal sign (=) in the center. We will set up an equation and solve for x.

[Equation]

x + 122 = 334

[Subtract 122 from both sides]

x = 212

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and

6 days give the following step function;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]

The temperature at it is fermented in the first three days = 70 °F

From day 3 to 6 the temperature = 50 °F

From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F

The step function is therefore;

[tex]\begin{cases}f(x) = 70^{\circ } & \text{ if } 0 \leq x \leq 3 \\f(x) = 50^{\circ} & \text{ if } 3 < x \leq 6 \\ f(x) = 35^{\circ }& \text{ if } 6 < x \leq 12 \end{cases}[/tex]
