Alani is the head baker at Patty Cakes Bakery.

aksik [14]

Answer:

1).Sugar used in 7 days = 61.25 pounds

2). Total cost of 9 cupcakes = $38.25

Step-by-step explanation:

1). Alani uses 8.75 pounds of sugar each day.

So, sugar used in 7 days = Amount of sugar used in one day × Number of days

= 8.75 × 7

= 61.25 pounds

2). Since, each cupcake costs $4.25

Number of cakes ordered = 9

Total cost of 9 cupcakes = Cost of each cupcake × Number of cupcakes

= 4.25 × 9

= $38.25

Line segment AB has endpoints A(1, 4) and B(6, 2). Find the coordinates of the point that divides the line segment directed from

VMariaS [17]

let's say that point is point C, thus

$\bf ~~~~~~~~~~~~\textit{internal division of a line segment}\\\\\\A(1,4)\qquad B(6,2)\qquad\qquad \stackrel{\textit{ratio from A to B}}{2:3}\\\\\\ \cfrac{A\underline{C}}{\underline{C} B} = \cfrac{2}{3}\implies \cfrac{A}{B} = \cfrac{2}{3}\implies 3A=2B\implies 3(1,4)=2(6,2)\\\\[-0.35em]~\dotfill\\\\C=\left(\frac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \frac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)\\\\[-0.35em]~\dotfill$

$\bf C=\left(\cfrac{(3\cdot 1)+(2\cdot 6)}{2+3}\quad ,\quad \cfrac{(3\cdot 4)+(2\cdot 2)}{2+3}\right)\implies C=\left(\cfrac{3+12}{5}~,~\cfrac{12+4}{5} \right)\\\\\\C=\left( \cfrac{15}{5}~,~\cfrac{16}{5} \right)\implies C=\left( 3~,~3\frac{1}{5} \right)$
