Answer 1

Step-by-step explanation:

Since ABC is a triangle,

Angle A + Angle B + Angle C = 180 (Sum of angles in a triangle)

given Angle A = 3x + 1

Angle B = 4x - 17

Angle C = 5x - 20

[tex]3x + 1 + (4x - 17) + (5x - 20) = 180 \\ 3x + 4x + 5x + 1 - 17 - 20 = 180 \\ 12x - 36 = 180 \\ 12x = 180 + 36 \\ 12x = 216 \\ x = 216 \div 12 \\ = 18[/tex]

Now substitute x into all 3 angles.

A = 3(18) + 1 = 54 + 1 = 55 degrees

B = 4(18) - 17 = 72 - 17 = 55 degrees

C = 5(18) - 20 = 90 - 20 = 70 degrees

Since Angle A = Angle B but not equal to Angle C,

Triangle ABC is a isosceles triangle as 2 angles must be the same for it to be a isosceles triangle.

At 7am there was 4 inches of snow on the ground. After that, the snow fell at a rate of 1.5 inches per hour. Equation:

Answers

Answer:

y(t) = 4 + 1.5t

Step-by-step explanation:

Initial amount of snow = 4 inches

Fall rate of snow = 1.5 inch per hour

Equation to model the scenario goes thus :

Initial amount of snow + (fall rate of snow * number of hours)

Let the number of hours = h

4 inches + (1.5 inch per hour * h)

Equation, y(t) becomes ;

y(t) = 4 + 1.5t

A car is traveling at a constant speed of 60 miles per hour. Complete the table below to the distance that the car travels in hours.

Answers

The value for the first one is “d= 60t”
because that’s how much the car travels per hour.
The values for the second question is “450=60t” because 450 is the amount of miles the car traveled in total, and again the 60 is how many miles the car travels per hour.

A biologist is studying a group of alligators in a swamp and tagged 4 hatchlings, 5 juveniles, and 6 adults. The biologist estimates that this tagged sample is a reliable reflection of the ratios of hatchlings, juveniles, and adults in the general alligator population for the area. The biologist estimates that the total number of alligators in the area is 120. The most likely number of adults in the total population is ______?

A. 32
B. 48

48 man hope this helps papi

Answer:

Step-by-step explanation: Take the 6 adults and divide it by one of the multiple choice answers to get a ratio. The ratio of 48 / 6 = 8. You can then see if that ratio helps you add up all the alligators to 120.

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other 2 sides, then the triangle is right

longest side = 52 and 52² = 2704

48² + (10 + 10)² = 48² + 20² = 2304 + 400 = 2704

Then AB is a tangent to the circle since ∠ B is a right angle

Manuel needs to buy plastic spoons. Brand Ahas a box of 12 spoons for $1.12. Brand B has a box of 25 spoons for 2.69 Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent. Unit price for the Brand A spoons: I for each spoon Unit price for the Brand B spoons: $] for each spoon The better buy: O Brand A O Brand B O Neither (They have the same unit price)

Answers

To find the price per spoon of brand A, divide the cost by the amount of spoons:

1.99 / 25 = 0.0796

Repeat this process for brand B:

3.89 / 42 = 0.0926

Brand A, at $0.08 a unit, is the better buy of brands A and B.

Answer:

Brand A: 0.92 Brand B: 0.11

Step-by-step explanation:

1.12 divided by 12 (round down)

2.96 divided by 25 (round up)

brand B is better to buy because you get more and it costs less per spoon
