Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

larisa86 [58]

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
x + y + z = 140 meters

According to the proportion theorem,

$\frac{x}{40} = \frac{y}{30}$

Solving for x, using cross multiplication:

$\frac{x}{1} = \frac{40y}{30}$

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

4y/3 + 6z/7 + 7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

What is unique about the members of the group of fungi to which Penicillium notatum belongs? They are not important for medicine

fgiga [73]

Answer:

The correct answer is - they are not made-up of hyphae.

Explanation:

Penicillin notatum is a member of fungi and penicillin genus. These fungi are present on salted foods, inside the house in damp parts mostly.

These fungi are not made up of hyphae. Hyphae are filamentous branches that form fungi body in other fungi groups. On this genus its more of like bush or brush.

Thus, the correct answer is option - they are not made up of hyphae.

Distinguish a virus from a prophage.

vazorg [7]

$\: \: \: \huge \color{blue} \boxed{ \colorbox{black}{Answer}}$

A prophage is a bacteriophage (often shortened to "phage") genome inserted and integrated into the circular bacterial DNA chromosome or exists as an extrachromosomal plasmid. This is a latent form of a phage, in which the viral genes are present in the bacterium without causing disruption of the bacterial cell.

Help please answer fast!!!

Murljashka [212]

Answer:

A graph not only depends on the data that we are graphing, there are other important factors such as the units we use (here we have °C vs years, but we could have °F vs days and we would see a different graph, which represents the exact same information) , the scale we use (a lot of graphs are misleading because of the use of logarithmic scales, we need to be clear about the scales we use), where we put the zero of each axis (We usually use the intersection of both axes as the (0, 0) point, but this is not a necessary condition, we could manipulate our coordinate axis as we want) , etc.

So there are a lot of things that can impact on how we see the graph of the same data.

About the second answer, one could interpret from that graph that the actual temperature between the years 1880 and 2020 was around 14°C.
