Please answer question

sweet-ann [11.9K]

Given;

ABCDE is similar to VWXYZ

so, the corresponding segments are proportional

We need to find the length of XY

XY is corresponding to CD

CD = 1.2 cm

Finding another two corresponding sides

DE = 3.2 cm , YZ = 4 cm

so,

$\begin{gathered} \frac{XY}{CD}=\frac{YZ}{DE} \\ \\ \frac{XY}{1.2}=\frac{4}{3.2} \\ \\ XY=\frac{4}{3.2}\cdot1.2=1.5\operatorname{cm} \end{gathered}$

So, the length of XY = 1.5 cm

Which one of the following reasons does NOT explain why 4x+5y≠9xy?

viva [34]

<h3>The terms 4x and 5y has different variable present in it. $4x + 5y \neq 9xy$ </h3>

Solution:

Given that,

$4x + 5y \neq 9xy$

The reason is:

When we are adding terms which has exactly the same variables, we must add the constants and let the result stand with variable

Which means,

4x + 10x = 14x

But,

We cannot add terms that has different variable

Which means,

4x + 5y

Here, both the terms 4x and 5y has different variable present in it. Hence they cannot be added together

$4x+5y\neq 9xy$

Doña Gertrudis recolecta en promedio 75 litros de leche de cabra por día y utiliza alrededor de 5 litros para hacer un kilogramo

Nimfa-mama [501]

Answer:

825 pesos a day on average

1 dozen weight = 2.4 kg

Step-by-step explanation:

In ENGLISH:

Doña Gertrudis collects on average 75 liters of goat milk per day and uses around 5 liters to make one kilogram of cheese. The cheeses he makes weigh 200 grams each and he sells them for 132 pesos a dozen. How much money do you get per day on average from the sale of your cheeses? How many kilograms does the dozen cheeses weigh?

Solution:

75 Liters / 5 Liters = 15

15 * 1 kg = 15 kg of cheese per day

15kg in grams is 15*1000 = 15,000 grams

Each cheese block is 200 grams, so number of blocks of cheese:

15,000/200 = 75 blocks of cheese

1 dozen (12) = 132 pesos, so 1 would be:

132/12 = 11 pesos PER BLOCK

SO, 75 blocks of cheese = 75 * 11 = 825 pesos (per day on average)

Dozen cheese weight in kg,

200 grams * 12 = 2400 grams

In kg,

2400/1000 = 2.4 kg

What is the width of it

notka56 [123]

The width of the rectangle is 16cm. this is because 16x4 = 64. so the height of the rectangle is 64 cm and 16cmx64cm = 1024cm squared. which is why the width of the rectangle is 16cm.
