To find out how many steel can porter recycled, you would have to use to equation (a)10w to find the total number.

A) 10w. You wouldn't add the 10 cans to the number of weeks to get the total and you wouldnt add 10 cans to the # of 10 cans times the # of weeks. a) 10w is the correct answer.

Answer:

330

Step-by-step explanation:

Hello There!

The shown figure is a trapezoid with the following dimensions:

Height - 11m

Base 1 - 41m

Base 2 - 19m

Given this information we need to find the area

Remember the formula for the area of a trapezoid is

$A=\frac{a+b}{2} h$

where a and b are bases and h is the height

Because we are given all of the information needed to calculate the area all we have to do is plug in the values into the formula

So...

$A=\frac{19+41}{2} 11\\19+41=60\\\frac{60}{2} =30\\30*11=330\\A=330$

In conclusion the area of the figure is 330 square units

Ab is 10. 8 units long if ABC is dilated by a scale factor of k equals 1.3 what is the length of a'b'

Marizza181 [45]

ANSWER

The length of

$A'B'=14.04 \: units$

EXPLANATION

The object length given to us is,

$|AB|=10.8 \: units$

The scale factor of the dilation is,

$k = 1.3$

The image length can be calculated using the formula

$|A'B'| = k \times |AB|$

We substitute the given values into the formula to get,

$|A'B'| = 1.3\times 10.8$

We multiply out to obtain,

$|A'B'| = 14.04 \: units$

1. Se tiene que 5 kilogramos (kg) de almendra y 4 kg de nuez cuestan $44.00, mientras que 8 kg de almendra y 6 kg de nuez cuesta

Sholpan [36]

Answer:

x = 6.00 $/kg ----> almond

y = 3.5 $/kg ------> nut

Step-by-step explanation:

To find the price per kg of each product you first write the algebraic equations for the given relations:

x : price per kg of almond

y: price per kg of nut

Then, you have:

5x + 4y = 44.00 (1)

8x + 6y = 69.00 (2)

By using substitution you have from (1):

y = (44.00-5x)/(4) = 11.00 - (5/4)x

you replace this expression for y into (2):

8x+6[11.00-(5/4)x] = 69.00

8x+66.00-(15/2)x = 69.00

8x-(15/2)x = 69.00 - 66.00

(1/2)x = 3.00

x = 6.00 $/kg ----> almond

And for nut:

y = 11.00 - (5/4)x = 11.00 - (5/4)(6.00) = 3.5$/kg

y = 3.5 $/kg ------> nut
