Step-by-step explanation:

the sum of all angles in a triangle is ALWAYS 180°.

and by using the word "congruent" : for angles that only means they are equally large.

we know the third angle.

so,

180 = P + Q + R = 2×P + 28.45

(because P = Q)

2×P = 151.55

P = Q = 151.55 / 2 = 75.775°

(5) All snow geese can eat for 11.5 days before the research and rescue center runs out of supplies.

What is snow geese?

Despite having a reputation for having white feathers, many snow geese are actually blue geese, which are darker, gray-brown birds. These birds were formerly believed to be two distinct species, however it has recently been discovered that they are actually just two color variants of the same bird. The variation in color is controlled by a single gene.

9 snow geese are housed in the research and rescue center.

Each geese consumed 16 ounces of seeds, therefore that's how much.

Therefore, the amount of seeds consumed by 9 snow geese is equal to (16*9) ounces.

144 ounces of seeds were consumed by 9 snow geese.

There are currently 1,656 ounces of seeds.

Thus, the number of days before the center runs out of food is equal to the sum of the ounces of seeds eaten by the nine snow geese divided by the total ounces of seeds.

Days till the food center runs out of supplies = 1656/144

11.5 days are required until the center runs out of food.

Hence, all snow geese can eat for 11.5 days before the research and rescue center runs out of supplies.

Answer:

2.5 × 10^-1

step-by-step explanation:

To get to standard form, you must move the decimal to the right one place so the number before it is not a 0. Because you move the decimal, you must add the second part of the equation so that the value does not change.

Answer:

02.5 but the 0 at the beginning isn't significant so 2.5

Step-by-step explanation:

because to find the standard form you move the decimal point so that there is only one non-zero digit in front of the decimal point.

The linear equation to represent the total cost c =  2.25s + 1,347.85.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

Using slope

slope= ( 5847. 75 - 4074 . 85)/( 2000- 1200)

slope= 1800 - 800

slope= 2.25

and, slope- intercept form

c - 4047.85 = 2.25 ( s- 1200)

c - 4047.85 = 2.25s - 2700

c = 2.25s - 2700 + 4047.85

c =  2.25s + 1,347.85

The dimensions of the ticket are width is 11 cm and  length is 18 cm.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

An airplane ticket has a perimeter of 58 cm and an area of 198 square cm.

Let W is the width of the ticket and L is the length of the ticket

The area of a credentials= L × W

198 = L × W ...(i)

The perimeter of a ticket = 2(L+W)

58 = 2(L+W)

29 = L + W

L = 29 - W ...(ii)

Substitute the value of L = 99 - W in equation (i)

198 = (29 - W) × W

198 = 29W - W²

0 = W² - 29W + 198

[tex]0=\left(W^2-11W\right)+\left(-18W+198\right)[/tex]

[tex]0=W\left(W-11\right)-18\left(W-11\right)[/tex]

[tex]0=\left(W-11\right)\left(W-18\right)[/tex]

W = 18 or 11

Substitute the value of W = 11 in equation (ii)

L = 29 - 11

L = 18

Thus, the dimensions of the ticket are width is 11 cm and length is 18 cm.

When there is 580 feet of fencing available to complete the job, the largest possible total area of the 5 pens is 7008.33 feet.

The quantity area expresses the extent of a region on a plane or curved surface.

STEP 1: We know that,

A=x y

The perimeter equals 580feet.

The equation is,

580=6x+2y

Step 2: Solving y terns with x,

y=-3x+290

This information will assist us in obtaining our Area equation in terms of a single variable (just in terms of x).

Step 3: Using the x-y relationship discovered in Step 2, write your Area equation in terms of x only. You should obtain

A=x y

A=x(-3x+290)

A=-3x²+290x

Step 4: Derive the area equation,  A' = -6x+290

Step 5: Set A' = 0

-6x+290=0

x=290/6

x=48.33

Step 6: Find y by substituting 48.33 in x in the perimeter equation then,

y=-3(48.33)+290

y=145.01

Step 7:  A=x y

A=(48.33)(145.01)

The required third number will be 12 when numbers are in the A.P.

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The given data as

first number = - 2

fifth number = 26

Assume that the given numbers are in the A.P.

The formula to find the general term of an arithmetic sequence is,

Tₙ = a₁ + (n-1)d  ...(i)

Substitute the value of n = 5 and a₁ = -2 in the above formula

T₅ = a₁ + (5-1)d

26 = -2 + 4d

4d = 28

d = 7

For finding the third term (number):

T₃ = -2 + (3-1)7

T₃ = -2 + (2)7

T₃ = -2 + 14

T₃ = 12

The scientist will take 23 seconds to get back to the sea level.

Let us calculate the distance covered by the scientist at the given speeds and at the specified times.

She travels down for 41 seconds at speed of 4.9 feet per second.

Distance travelled = 41 × 4.9 = 200.9 feet

Elevation = -200.9 feet

She then goes up for 49 seconds at speed of 3.2 feet per second.

Distance travelled = 49 × 3.2 = 156.8 feet

Elevation = -222.9 + 156.8 = -44.1

So she is at a depth of 44.1 feet below the sea level.

Time taken = 44.1 / 3.6 = 12.25 seconds

Therefore it will take her about 12.25 seconds to go back to the sea level.

The average surface level of one or more of the Earth's coastal bodies of water is known as mean sea level (MSL), which can be used to calculate heights like elevation.

The measure of the exterior angle of the triangle is 144 degrees.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

Therefore, the measure of the two remote interior angles of a triangle are x - 10 and 4x + 4. The exterior angle of the triangle measures 3x + 54 .

Let's solve for the exterior angle.

x - 10 + 4x + 4 = 3x + 54

5x - 6 = 3x + 54

5x - 3x = 54 + 6

2x = 60

x = 60 / 2

x = 30

The solution to the variable x is 12 and the measure of ∠B is 48°.

∠A = 5x−12°

∠B = 2x+24°

Angle A and Angle B are congruent angles.

Congruent angles are angles with the same or equal measures.

So,

∠A = ∠B

5x - 12 = 2x + 24

5x - 2x = 24 + 12

3x = 36

divide both sides by 3

x = 36/3

x = 12

So therefore,

∠A = 5x−12°

= 5(12) - 12

= 60 - 12

= 48°

∠B = 2x+24°

= 2(12) + 24
