PLEASE HELP WILL MARK BRAINLIEST!!

Answer:

79 minutes

Step-by-step explanation:

A plane is travelling at 180 meters per seconds

Convert to km/hr

180× 18/5

= 648 km/hr

Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is

= 1/648 × 800

= 1 hour 19 minutes

Conver the time to full minutes

60 minutes = 1 hour

= 60+19

= 79 minutes

Hence the minutes required for the plane to travel 800km is 79 minutes

Answer:

F=2x^2+24

Step-by-step explanation:

F (x+3)=2x^2+6

F=2(x+3)^2+6

F=2(X^2+9)+6

F=2x^2+18+6

F=2x^2+24

Answer:

18 inches

Step-by-step explanation:

volume of a cuboid = length x breadth x height

the following equation can be derived from the question

let h = unknown height

1/3(24 x 15 x h) = (12 x 18 x 10)

Multiply both sides of the equation by 3

(24 x 15 x h) = (12 x 18 x 10) x 3

Divide both sides of the equation by (24 x 15)

h = 18 inches

When you have an irregular figure, you can divide it so that it becomes multiple normal figures. You already did this in the picture, now you just have to find the area of each shape and then add them all together.

From bottom to top:

A=1/2 (b1+b2)h

A= 1/2 (4+2.24)(2)

A= 6.24

(you have two of these on either side)

A=bh

A=6(4)

A=24

A=1/2 bh

A= 1/2 (4)(4)

A=8

(NOTE: there is an error in your drawing. The height of the triangle cant be determined because the 10 value spans over the entire figure when the wings of the rocket are 4 units long and then the body is 6 units long, making it equal 10 already. I'm assuming that the 10 is supposed to go from the bottom of the rectangle to the top of the triangle)

Total figure= 6.24 + 6.24 + 24 + 8

total figure = 44.48

Answer:

6x² - 4

Step-by-step explanation:

Given

4(x² - 3) + 2x² + 8 ← distribute parenthesis

= 4x² - 12 + 2x² + 8 ← collect like terms

= 6x² - 4

4(2−3)+22+8

42−12+22+8

42−12+22+8

42−4+22

42−4+22

Answer:

Volume of the cooler = 2,772 in³

Step-by-step explanation:

Volume of the cooler = length × width × height

Length = 22 in

Width = 12 in

Height = 10 1/2 in

= 21/2

= 10.5 in

Volume of the cooler = length × width × height

= 22 in × 12 in × 10.5 in

= 2,772 in³

Volume of the cooler = 2,772 in³

Answer:

b ≈ 8.49

Step-by-step explanation:

A^2 + b^2 = c^2.   (Pythagorean theorem)

c is the hypotenuse or the longest side of a triangle.

a and b are the other 2 sides.

17^2 + b^2 = 19^2

289 + b^2 = 361

289 + b^2 - 289 = 361 - 289

b^2 = 72

b ≈ 8.49

Answer:

It is a permutation problem. There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.

Step-by-step explanation:

In this case, the company will hire four different applicants from a group of 40 people for 4 different jobs. In this case, we need to consider the effect of order in the number of possibilities. Hence, we must use the permutation formula:

[tex]_{n} P_{k} = \frac{n!}{(n-k)!}[/tex] (1)

Where:

[tex]n[/tex] - Total of applicants.

[tex]k[/tex] - Selected applicants.

If we know that [tex]n = 40[/tex] and [tex]k = 4[/tex], then the number of possibilities is:

[tex]_{40}P_{4} = \frac{40!}{(40-4)!}[/tex]

[tex]_{40}P_{4} = 40\times 39 \times 38 \times 37[/tex]

[tex]_{40}P_{4} = 2193360[/tex]

There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.

Step-by-step explanation:

All the step of construction is explained below. The required regular hexagon is given below.

Construct a regular hexagon inscribed in a circle using the construction tool. Insert a screenshot of the construction here.

In the first step, make a circle with a radius, and connect the center and circumference.

In the second step, make an angle which is calculated by the formula.

⇒ 360 / n

Where n is the number of sides of the polygon. Then we have

⇒ 360 / 6 = 60

In the third step, take protector or arc length of the circumference and cut the another arc.

In the fourth step, connect all the point.

Answer: A. Suzy made an error going from Step 1 to Step 2.

Step-by-step explanation: Following the order of operations (PEMDAS), we know that exponents are dealt with before multiplication. Suzy used the distributive property of multiplication going from step 1 to step 2, rather than working with the exponent.

Answer:

TQ=SR [since it is isosceles trapezoid]

6x+1.2=9x-48

48+1.2=9x-6x

3x=49.2

x=49.2/3=16.4

now

QR=3×16.4+2.5=51.7

SR=9×16.4-48=99.6

ST=4×16.4-2=63.6

TQ=6×16.4+1.2=99.6

As it's isosceles trapezoid

Now

QR=3(2)+2.5=8.5

RS=9(2)-4.8=13.2

ST=4(2)-2=6

QT=6(2)-1.2=10.8

Answer:

m<3 = 108

Step-by-step explanation:

Since <1 and <2 are supplementary, the equation is:

<1 + <2 = 180

Since <1 and <3 are vertical angles. the equation is:

<1 = <3

To find m<3:

<2 + <3 = 180

72 + <3 = 180

<3 = 180 - 72

<3 = 108

The measure of angle ∠3 is 108 degrees.

Supplementary angles are those angles that sum up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees.

Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.

For the given situation,

∠1 and ∠2 are supplementary angles.

∠1 and ∠3 are vertical angles.

Measure of angle, m ∠2 = 72

From definition, we know that

∠1 + ∠2 = 180 (supplementary angles) ------- (1)

and

∠1 = ∠3 (vertical angles) --------- (2)

From (1) and (2),

⇒ [tex]\angle3 + \angle2 = 180[/tex]

⇒ [tex]\angle3=180-72[/tex]

⇒ [tex]\angle3=108[/tex]

Hence we can conclude that the measure of angle ∠3 is 108 degrees.
