Answer:

1/100

Step-by-step explanation:

the problem description is not copied fully.

but I think I understand it.

since the ratio of the perimeter is 1/10, so is then also the ratio for each side.

that means the longest side of ABC is 4 units (40/10), right ?

anyway, when the ratio of lengths and distance is 1/10, then the ratio for the area is 1/10×1/10 = 1/100.

because for the area (baseline × height / 2) two lengths have to be multiplied. and that multiplies the scaling factor twice into the calculation effectively squaring it as the area scaling factor.

and 1/10×1/10 = (1/10)² = 1/100

\measuredangle BAC = 29°

Answer:

\measuredangle BOC =58°

Step-by-step explanation:

\measuredangle BDC = 29°...(Given) \\\because \measuredangle BAC = \measuredangle BDC\\(\angle 's \: subtended \: by\: same\: arc) \\\huge \purple {\boxed {\therefore \measuredangle BAC = 29°}} \\\\

Since, angle subtended on the center of the circle is twice the angle subtended on the circumference of the circle.

\therefore \measuredangle BOC =2\times \measuredangle BDC\\\therefore \measuredangle BOC =2\times 29°\\\huge \red {\boxed {\therefore \measuredangle BOC =58°}} \\

Gabe went to the amusement park with $40 to spend. His ticket cost $26.50. Write and solve an inequality to show how much he mig
Goshia [24]
<h3><u>An inequality to show how much he might spend on souvenirs and snacks is:</u></h3>

x\leq 13.5

<h3><u>Solution:</u></h3>

Given that,

Gabe went to the amusement park with $40 to spend

His ticket cost $26.50

Therefore,

Total amount she has = $ 40

Ticket cost = $ 26.50

Let "x" be the amount he might spend on souvenirs and snacks

Therefore,

Remaining amount = 40 - 26.50

Remaining amount = 13.5

Thus she can spend less than or equal to $ 13.5 on souvenirs and snacks

Which is represented in inequality as:

x\leq 13.5

Thus the inequality is found
