Hmm... That's hard!

Well, I ended up with 19 7/10 but I'm a bit sure its incorrect. Here's how I got my answer.

First, you look what's in the parentheses. -20 1/2. Hmm. Just that? Then look at the number outside. 4/5. Just subtract 20 1/2 and 4/5. If there was no subtraction sign, you could've just multiplied... but teachers just want to melt your brain...

g A restaurant offers 7 entrees and 11 desserts. In how many ways can a person order a two-course meal?

Kitty [74]

Answer:

$2-course\ meal = 77\ ways$

Step-by-step explanation:

Given

$Entrees = 7$

$Desserts = 11$

Required

Determine the number of ways to get a two-course meal

This is solved as follows:

<em>The entrees can be ordered in 7 ways</em>

<em>The desserts can be ordered in 11 ways;</em>

$2-course\ meal = Entrees * Desserts$

Hence:

$2-course\ meal = 7 * 11$

$2-course\ meal = 77\ ways$

Kayla wants to find the width, AB, of a river. She walks along the edge of the river 65 ft and marks point C. Then she walks 25

AlladinOne [14]

Answer:

Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles

Part B) The width of the river is about $39\ ft$

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

Part A) we know that

In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent

so

m<DCE=m<ACB -----> by vertical angles

m<EDC=m<ABC -----> is a right angle

m<DEC=m<CAB -----> the sum of the internal angles must be equal to 180 degrees

Part B) we know that

The triangles ABC and EDC are similar -------> see Part A

therefore

$\frac{BC}{DC}=\frac{AB}{DE}$

substitute the values and solve for AB

$\frac{65}{25}=\frac{AB}{15}$

$AB=15*(\frac{65}{25})=39\ ft$
