2. m∠A = m∠ B                                               All right angles are congruent.

3. ∠BEC≅ ∠AED                                              Vertical angles are congruent

4. ΔCBE ~ ΔDAE                                               AA

Step-by-step explanation:

A proof always begins with the givens.

1. ∠A and ∠B are right angles. -------------->Given

2. m∠A = m∠ B  are equal since----------->  All right angles are congruent.

3. ∠BEC≅ ∠AED  are also equal since---->Vertical angles are congruent

4. ΔCBE ~ ΔDAE since two angles are equal----------> AA

the local store is having a sale on ground beef- $10 for 3 pounds. sylvia needs 12 pounds of meat to make 50 hamburgers. how muc
Rashid [163]
10/3 = x / 12.....$ 10 to 3 lbs = $ x to 12 lbs
cross multiply
3x = 120
x = 120/3
x = 40....so it is gonna cost Sylvia $ 40 for the meat.

she plans on making 50 burgers......40 ($ worth of meat) / 50 (burgers)  = 
0.8....so for each burger, the meat will cost 0.80 or 80 cents <==

1. Scientific Notation and Percent. (Based on the ideas in Objective 1 and Objective 4.) 6 points
vlabodo [156]

Answer: 1.715*10^{12} skin cells were not burned.

Step-by-step explanation:

<h3><u> The complete exercise is: Two percent of Sennie's skin cells were burned when she escaped from a fire. If 3.5*10^{10} of her skin cells were burned then, how many skin cells were not burned?​</u></h3><h3 />

Let be "x" the number of Sennie's skin cells that were not burned when she escaped from the fire.

According the the data given in the exercise, you know that 2% represents 3.5*10^{10} of Sennie's skin cells that were burned. This means that the percent of her skin cells that were not burned is:

100\%-2\%=98\%

With this information you can write the following proportion:

\frac{3.5*10^{10}}{2}=\frac{x}{98}

Solving for "x", you get:

(98)(\frac{3.5*10^{10}}{2})=x\\\\x=171.5*10^{10}

To express the result in Scientific notation, the decimal point must be after the first digit; then you must  move the decimal point two places to the left:

x=1.715*10^{12}

A woman wants to build a rectangular garden. She plans to use a side of a shed for one side of the garden. She has 84 yd of fenc
Ivan
Let x denote the length of the side of the garden which is covered fenced by a shed, and \frac{A}{x} be the width of the garden.

The perimeter of a rectangle is given by 2(length + width)
i.e. 2x + \frac{A}{x} = 84
which gives:
A = 84x - 2x^2

For the area to be maximum, the differentiation of A with respect to x must be equal to 0.
i.e. \frac{dA}{dx} =84-4x=0 \\ 4x=84 \\ x=21

Therefore, the maximum area of the garden enclosed is given by
84(21)-2(21)^2=1764-2(441)=1764-882=882 \, yd^2
