Ginny is making homemade pizzas for her family. The recipe makes 70 ounces of dough, but she made more that to ensure she had en
Anastaziya [24]

Answer:

14 ounce

Step-by-step explanation:

Given that:

Ounces of dough used in making recipe = 70 ounces

Number of ounces frozen = 28 ounces

Number of pizzas made from dough left = 3

Number of ounces left = total made - number frozen

Number of ounces left = 70 - 28 = 42

Weight of pizza made :

Number of ounces left / number of Pizzas made

42 / 3 = 14

Hence, maximum weight of each pizza made will weigh more than 14 ounces

A line passes through the point(-4,-6) and has a slope of 1/2 What is the<br> equation of the line?
alex41 [277]

Answer:

x-2y-8=0

Step-by-step explanation:

The equation of line is given by the relation

y-y1=m(x-x1)

where m is the slope

now, given x1=-4 and y1=-6 and the slope is 1/2.

<em>sub</em><em>stitute</em><em> </em><em>in</em><em>to</em><em> the</em><em> equation</em><em> </em><em>to</em><em> </em><em>get</em>

<em>y</em><em>+</em><em>6</em><em>=</em><em>1</em><em>/</em><em>2</em><em>(</em><em>x</em><em>+</em><em>4</em><em>)</em>

<em>mult</em><em>iplying</em><em> </em><em>through</em><em> </em><em>wi</em><em>th</em><em> </em><em>the</em><em> </em><em>L.C.M</em>

<em>whi</em><em>ch</em><em> </em><em>is</em><em> </em><em>2</em>

<em>2</em><em>(</em><em>y</em><em>+</em><em>6</em><em>)</em><em>=</em><em>1</em><em>/</em><em>2</em><em>×</em><em>2</em><em>(</em><em>x</em><em>+</em><em>4</em><em>)</em>

<em>2</em><em>y</em><em>+</em><em>1</em><em>2</em><em>=</em><em>x</em><em>+</em><em>4</em>

<em>maki</em><em>ng</em><em> </em><em>x</em><em> </em><em>the</em><em> </em><em>su</em><em>bject</em>

<em>x</em><em>=</em><em> </em><em>2</em><em>y</em><em>+</em><em>8</em><em> </em><em>hence</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>li</em><em>ne</em><em> </em><em>is</em><em> </em><em>x-2y-8</em><em> </em><em>=</em><em>0</em>

The sum of theee consecutive numbers is 90. what is the smallest of the three numbers?
zlopas [31]

29

Note that consecutive numbers have a difference of 1 between them.

let n be the smallest integer then the three integers can be expressed as

n, n + 1 , n + 2

the sum is then

n + n + 1 + n + 2 = 90

3n + 3 = 90

subtract 3 from both sides of the equation

3n = 90 - 3 = 87

divide both sides by 3

n = \frac{87}{3} = 29

the three integers are 29, 30, 31 → the smallest is 29

Check the picture below.

so our bases are "d" and "d+a+b", and a height of "c".

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(x+y)}{2}~~ \begin{cases} x,y=\stackrel{parallel~sides}{bases}\\ h~~~=height\\ \cline{1-1} x=d\\ y=d+a+b\\ h=c\\ A=(d+b)c \end{cases}\implies (d+b)c=\cfrac{c[d+(d+a+b)]}{2} \\\\\\ 2(d+b)c=c[d+(d+a+b)]\implies 2dc+2bc=c(2d+a+b)

\bf ~~\begin{matrix} 2dc \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~+2bc=~~\begin{matrix} 2dc \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~+ac+bc\implies 2bc=ac+bc\implies 2bc=c(a+b) \\\\\\ \cfrac{2b~~\begin{matrix} c \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{~~\begin{matrix} c \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}=a+b\implies 2b=a+b\implies 2b-b=a\implies \blacktriangleright b=a \blacktriangleleft
