Please help me I am in need of help!

Answer:

4.75b; 8

Step-by-step explanation:

Area of triangle: height ÷ 2 × base

38 = 9.5 ÷ 2 × b

    = 4.75 × b

38 = 4.75b

b = 38 ÷ 4.75

b = 8

Answer:

4.75 & 8

Step-by-step explanation:

Answer:

x = 32

Step-by-step explanation:

x + 10 = 42, then you subtract 10 from both sides to get 32

Answer:

976.38 (rounded to the nearest hundredth)

Step-by-step explanation:

11 x 3728 = 41008

7 x 6 = 42

41008/42 = 976.38 (rounded to the nearest hundredth)

Answer:

24.5

Step-by-step explanation:

Answer:

v= -19

Step-by-step explanation:

Solve for  V  by simplifying both sides of the equation, then isolating the variable.

Answer:

-19

Step-by-step explanation:

+19 -19 = 0

Therefore,

V = -19

Subtract 19 from both sides 0 - 19 = -19,

-19 = V

Answer:

Step-by-step explanation:

This is a geometric sequence; we know that because of the words "common ratio."  The general formula for a geometric sequence is

a(n) = a(1)*r^(n - 1), where r is the common ratio.

Here, a(1) = 1, r = 1/3, and so

a(1) = 1 (given)

a(2) = 1/3 (this is a(1) multiplied by 1/3)

a(3) = 1/9 (this is a(2) multiplied by 1/3)

a(4) = 1/27

a(5) = 1/81

Answer:

2

Step-by-step explanation:

1 + 1 = 2

Number Order: 1 2 3 4 5 6...

1 plus an additional value of 1 gives us the next number which is 2

Step-by-step explanation:

Airplane One 425m/h x 2h= 850 miles traveled N5°W

Airplane Two 530m/h x 2h= 1060 miles traveled N67°E

5 degrees + 67 degrees = 72 degrees divergence of the Airplane One and Two

Draw a triangle, the smallest side is 850 and adjacent to 1060 side. The angle between these two sides is 72 degrees

Use the acronym SOH CAH TOA to find the side which is the distance between the 2 airplanes after 2 hours

sine 72= opposite/hypotheneus

sine 72= opposite/1060

opposite = (sine 72)(1060)= 1008 miles distance between Airplane One and Airplane Two

The area of a triangle is 1/2 x base x height.

The area of the triangle is 1/2 x 6 x 8 = 24 square cm.

There are 4 identical triangles so 24 x 4 = 96 square cm.

The area of the square base = 6 x 6 = 36 square cm.

Total area = 96 + 36 = 132 square cm.

Answer:

12 green marbles

Step-by-step explanation:

in this case we have to add the the green marbles as 4 and red marbles as 9

so, 4 + 9 = 13 and divide the total marbles to it

so, 39/13 = 3

so, here we have 3 times marble in 13 green marble to get the total number

so, 3 (13)

so, in this case we have to separate the green and red

so, 13 as ( 9 red + 4 green)

so,3 times  ( 9 red + 4 green)

in this case we can use distributive property of multiplication

so, 3 times 9 red = 27 is the total red marbles

and 3 times 4 green = 12 is the total green marbles

to check the answer we have to add this two

so, 27 red marbles + 12 green marbles = 39 total marbles

so, that's why it is 12 green marbles

Answer:

-6

Step-by-step explanation:

3+7=10

10-6=4

so 3+7-6=+4

Answer:

6

Step-by-step explanation:

= means the same as

3+7 = 10

therefore 4 + ?=10

10-4=6

therefore the missing number is 6

=6

Answer:

AC=30

BD=30

BE=15

AB=27

Answer:

AC = 30, BD = 30, BE = 15, AB = 27, BC = 13.1

Step-by-step explanation:

AC = AE * 2

BD = BE * 2

BE = AE

AB = CD

BC = [tex]\sqrt{30^{2}-27^{2} }[/tex] (Pythagorean theorem)

Answer:

hello your question is incomplete  below is the complete question

A company's human resources department was interested in the average number of years that a person works before retiring. The sample of size 11 follows: 12 16 18 19,21 21, 21,22 24 24 26What is the arithmetic mean, median and mode? what is the most likely shape of the distribution

answer :

i) mean = 20.36

ii) median = 21

iii) mode = 21

iv) The most likely shape is a Bell - shaped curve

Step-by-step explanation:

sample size = 11

values ( observations ) = 12, 16, 18, 19,21,21,21,22,24,24,26

i) mean

 = ∑ values / sample size = 224 / 11 = 20.36

ii) median

median is the value of the data located at the center of the string of data

to determine the middle position = ( n+1 / 2 )

where n = sample size

hence position of median value = 11 + 1 / 2 = 12 / 2 = 6

the value at the 6th position = 21 ( median )

iii) mode

mode = most repeated value in the series of data

hence mode value = 21

Step-by-step explanation:

Answer:

We combine x ounces of 100% juice

with 40-x of 10% juice

to get 40 ounces of 55% juice

x + 0.1(40-x) = .55(40)

x + 4 - 0.1x = 22

0.9x + 4 = 22

.09x = 18

x = 20 ounces of 100% juice

40-x = 20 ounces of 10% juice

We combine 20 ounces of each.
