Step-by-step explanation:

The height of the tree to the nearest hundredth of a meter is 1.875 meters.

Given that:

Khalil is 1.65 meters tall. At 3 p.m., he measures the length of a tree's shadow to be 34.55 meters. He stands 30.4 meters away from the tree, so that the tip of his shadow meets the tip of the tree's shadow.

Let h be the height of khalil h = 1.65 , H be the tree height , L be the length of the tree's shadow L = 34.55 and l be the length of khalil shadow l = 30.4

Using equivalent ratios of heights:

h : H = l : L

H : 1.65 = 34.55 : 30.4

H/1.65 = 34.55/30.4

H = 34.55/30.4 * 1.65

on solving

H = 1.875 meters which is tree height

Therefore the height of the tree to the nearest hundredth of a meter is 1.875 meters.

Ok done. Thank to me >:33

Answer:

Step-by-step explanation:

14) Amount in Harper's school lunch account = $ 75

Cos of one meal = $ 3.25

Cost of 'm' meals = 3.25 * m = 3.25m

Balance amount in Harper's account after getting 'm' meals = $ 19.75

Total amount - Cost of 'm' meals = 19.75

      75 - 3.25m = 19.75

         To find the value of 'm', isolate m. To isolare m subtract 75 from both sides

             -3.25m = 19.75 - 75

             -3.25m  = -55.25

Now divide both sides by (-3.25)

                     m = -55.25/(-3.25)

m = 17

15) Starting height = 24 ft

Height after t seconds = 4.5*t = 4.5t

To see the river, the drone should reach the height atleast 330 ft above the ground. ⇒ It should be at the height greater than or equal to 330 ft

Initial height + height after 't' seconds ≥ 330

24 +  4.5t ≥ 330

Subtract 24 from both sides

          4.5t ≥ 330 - 24

          4.5t ≥ 306

Divide both sides by 4.5

    t ≥ 306/4.5

     t ≥ 68

He will be able to see the river from 68 seconds ( 1 minute 8 seconds)  and above.

No, Imani will not be able to the river after the drone has been raising  for one minute. At 1 minute 8 seconds Imani will start seeing the river. So at one minute, the drone will not have reached the required height .

Answer:

Exact form would be 1/64

Decimal form would be 0.015625

Step-by-step explanation:

The first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k is to factor out 6 from the first two terms

The standard vertx form of an expression is given as  y = a(x – h)^2 + k

Given the quadratic expression given as:

y = 6x^2  + 18x+ 14

Before a quadratic equation can be transformed to its vertex form, the coefiicient of x^2 must be 1.

To do that, you will factor out 6 from the first two terms to have:

6(x^2 + 3x) + 14

Hence the first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k is to factor out 6 from the first two terms

Answer:

$41739.13

Step-by-step explanation:

We will start by creating an equation for the problem.

Set Rodney's salary before the increase as [tex]x[/tex].

Changing the 15% to a decimal and making sure it's an increase we get 1.15

If we work backwards we get the equation:

[tex](1.15)x=48000[/tex]
[tex]\text{Solving for } x\text{ we divide }48000 \text{ by } 1.15 \text{ and we get the answer of } 41739.13[/tex]

From the calculations;

The equations of motion are used in kinematics to obtain the various variables that has to do with motion.

In this case;

distance covered = 30 ft

initial velocity = 40 ft/second

Final velocity = 0 m/s at the maximum height

Hence;

v^2 = u^2 - 2gh

since v = 0

u^2 = 2gh

h = u^2/2g

h = (40)^2/2(9.8)

h = 82 feet

highest point above the ground = 82 feet + 30 feet = 112 feet

Now;

v = u - gt

since v = 0

u = gt

t = u/g

t = 40/9.8

t = 4 seconds

Time taken to hit the ground = 2(4 seconds) = 8 seconds

to solve this equation you should start by subtract 6 on both sides

-2x <= 3x + 35

then subtract 3x to both sides

-5x <= 35

then you divide both sides by -5

x => -7

you must change the signs because you multiplied it by a negative

Answer:

8 feet = 2 ²/₃ yards

Step-by-step explanation:

1 yard = 3 feet

Given width = 2 yards

⇒ width = 2 × 3 = 6 feet

Area of a rectangle = width × length

⇒ 48 ft² = 6 ft × length

⇒ length = 48 ft² ÷ 6 ft

⇒ length = 8 ft

To convert the length to yards, divide by 3:

⇒ 8 ÷ 3 = 2 ²/₃ yards

Answer:

(10 , 3)

Step-by-step explanation:

When you reflect over the y-axis, you are flipping the sign of the x-coordinate.

Likewise, when you reflect over the x-axis, you are flipping the sign of the y-coordinate.

In this case, you are reflecting over the y-axis, and the pair given to you is (-10, 3). When you reflect over the y-axis, you must flip the sign of the x-coordinate.

(-10 , 3) reflected over the y-axis is (10 , 3).
