Answer:

19. 5 feets

Step-by-step explanation:

Shadow of tree = 26 feets

Height of flower = 3 feets

Shadow of flower = 4 feets

Height of sun Innthe sky:

Shadow of flower / height of flower

= 4/3 = 1.333333

Height of tree:

Shadow of tree / height of sun

26 feets / 1.33333

= 19.5 feets

Hence, height of tree = 19.5 feets

The mean of the temperatures in the chart is 24° with a standard deviation of 4°. which temperature is within one standard devia

babymother [125]

Given: Mean temperature μ = 24 , standard deviation σ =4

The lower and upper bound for temperature within one standard deviation of the mean is given by,

Lower bound = μ - σ = 24 - 4

Lower bound = 20

Upper bound = μ + σ = 24+ 4

Upper bound = 28

The temperature value between (20, 28) is said to be within one standard deviation of the mean.

From given option 27° lies in between (20°, 28°), hence 27° is the temperature value that is within one standard deviation of mean.

Find the unknown angles

damaskus [11]

Answer: Hi!

Since this is a right triangle, we already know that one angle is 90 degrees. Since the angles of a triangle all add up to 180 degrees, and the two unknown angles will be equal, all we have to do is subtract 90 from 180 and then divide the difference by 2!

180 - 90 = 90

90 ÷ 2 = 45

The two missing angles are each 45 degrees.

(x = 45 and y = 45)

Make sure to put the degrees sign after your answers!

Hope this helps!

Fill in the blank distributive property

Sav [38]

$4(20+1)=4(20)+4(1)=80+4=84$

It's still just easier to add first though.
