yesLA; ΔBDA ≅ ΔBDCStep-by-step explanation:
Segment BD is a leg of the right triangles. It is congruent to itself (whether or not it is marked). Angles A and C are corresponding acute angles in the right triangles. They are marked as congruent to each other.
The triangles are congruent by the LA theorem, applicable to right triangles. The congruency statement can be written as ...

Suppose the first coil of wire illustrated in the simulation is wound around the iron core 6 times. Suppose the second coil is wound around the core N2 = 12 times. Shortly after the switch has been closed, the flux through the second coil of wire changes from 1.9 Wb per turn to 2.4 Wb in each turn of wire over a time interval of 0.2 s. Find the magnitude of the emf induced in the coil.
Answers
Answer:
30 V
Step-by-step explanation:
The induced emf, ε = -ΔΦ/Δt where ΔΦ = change in magnetic flux and Δt = time interval for change in flux.
Since we have N₂ = number of turns on second coil = 12 and initial flux per turn = 1.9 Wb per turn. The total initial flux per turn Φ₁ = 12 turns × 1.9 Wb per turn = 22.8 Wb.
Also, since we have N₂ = number of turns on second coil = 12 and final flux per turn = 2.4 Wb per turn. The total initial flux per turn Φ₂ = 12 turns × 2.4 Wb per turn = 28.8 Wb.
Since Δt = 0.2 s and the magnitude of the induced emf in the second coil, ε = ΔΦ/Δt
= (Φ₂ - Φ₁)/Δt
= (28.8 Wb - 22.8 Wb)/0.2 s
= 6.0 Wb/0.2 s
= 30 V
A peach weighs 65 grams. If you buy 10 peaches and they sell for $5.50 per kilogram, how much will they cost? Please helpppppp!!!!!! This is due in 10 minutes with expiation pleasee thank you

A researcher would like to study the relationship between average fuel economy (measured in miles per
gallon) and fuel type (premium, regular unleaded, and E85). He randomly selects 90 vehicles of various
makes and models, including compact cars, full-size cars, and trucks. All of the selected vehicles have
been driven less than 6,000 miles before the experiment.
a) Does this experiment use a control group? Explain.
b) Suppose the researcher would like to use a completely randomized design. Explain how the
researcher should assign the 90 vehicles to the three fuel types.
c) An advisor to the researcher suggests using a randomized block design. Should the researcher
block on type of vehicle (compact cars, full-size cars, and trucks) or number of miles previously
driven (0–2,000 miles; 2,000–4,000 miles; and 4,000–6,000 miles)? Explain your choice of

What is Survey?In order to gather information about a service, product, or process, a survey is described as the act of looking at a process or questioning a predetermined sample of people. Surveys used to gather data ask a specific set of people about their beliefs, actions, or knowledge.
Given:
a) No, there isn't a control group in this trial. This is evident from the fact that all of the gasoline tyres are being evaluated in all of the different automobile types; no specific group is under supervision.
b )In order to randomly assign Groups 1, 2, and 3 to each of the three feel kinds, the researcher should utilise a computer generator to run through the 90 generators.
c) Miles driven should be used as a criterion for blocking rather than vehicle type because the latter could have an impact on fuel economy.

Which is a correct first step in solving the inequality –4(2x – 1) > 5 – 3x?
Distribute –4 to get –8x + 4 > 5 – 3x.
Distribute –4 to get –8x – 1 > 5 – 3x.
Subtract 2x from both sides of the inequality.
Add 1 to both sides of the inequality.
Answers
Answer:
Step-by-step explanation:
Distribute –4 to get –8x + 4 > 5 – 3x.
We can actually deduce here that the correct first step in solving the inequality –4(2x – 1) > 5 – 3x is: A. Distribute –4 to get –8x + 4 > 5 – 3x.
What is inequality?An inequality refers to the relationship that exist between two expressions that shows that they are not equal to each other. The signs used in an inequality are:
≠ ‘not equal to’, > ‘greater than’, < ‘less than’, etc.We see here that the first step is to use -4 to multiply the digits in the bracket. If that happens, we will have: –8x + 4 > 5 – 3x.
Then solving the inequality:
-8x + 3x > 5 - 4
-5x > 1
x < -1/5
Thus, we see that option B: Distribute –4 to get –8x + 4 > 5 – 3x. is the correct answer.

#2. A field of grass feeds 36 cows for 4 days. How
many days would the same field feed 20 cows?
Answers
162 cow-days
Since the initial grass and the grass accumulated over 4 days is equal to 144 cow-days, the initial grass is equal to (144 − 36) or 108 cow-days. Now, to find the answer to the question: in 18 days, the grass accumulation is equal to 18 ∗ 9 or 162 cow-days.
Please consider marking brainliest! :)
Using the principle of proportional relationship, it will take 20 cows 7.2 days.
Setting up the relationship thus :
36 cows = 4 days
Hence, if they eact at the same rate ;
1 cow = 36 × 4 = 144 days
Hence, for 20 cows, it will take;
144 days ÷ 20
= 7.2 days
Hence, 20 cows will feed on the grass for 7.2 days

To get the slope= y-y divide x-x which is = 3-5 divide 6-3
= -2/3
So the equation will be :
Y=mx+b
Y=-2/3x+b
Now to get the b which is the yinter. We have to put a “x” and a “y “
