The marching band is selling candy bars and fruit snacks for a fundraiser. Candy bars are sold for $2.50 and fruit snacks are $1
Flauer [41]

Answer:

220 candy bars

Step-by-step explanation:

Let the number of candy bars sold=c

Let the number of fruit snacks sold=f

A total of 650 items were sold.

  • Therefore: c+f=650

Candy bars are sold for $2.50

Fruit snacks are sold for $1.50

Total Income =$1,195

  • Therefore: 2.5c+1.5f=1195

We solve the resulting system of equation for c, the number of candy bars sold.

  • c+f=650
  • 2.5c+1.5f=1195

From the first equation, f=650-c

Substitute f=650-c into 2.5c+1.5f=1195

2.5c+1.5(650-c)=1195

2.5c+975-1.5c=1195

Collect like terms

2.5c-1.5c=1195-975

c=220

Therefore, 220 candy bars were sold.

Based on the information marked in the diagram, ABC and DEF must be congruent.
drek231 [11]

Answer:

Option A is correct

True, ΔABC and ΔDEF must be congruent.

Explanation:

LA theorem or Postulates states that given two right triangles,  where one acute angle and a leg of one of the triangles are congruent to  an angle and a leg of the other triangle, then the two triangles are congruent.

In  ΔABC and ΔDEF

AB = DE              [Leg]                [Given in the figure]

\angle BAC = \angle EDF = 90^{\circ}     [Given]

\angle BCA = \angle EFD   [Acute angle]        [Given in the figure]

Then, by the LA theorem or Postulates;

therefore, ΔABC \cong ΔDEF .
