What is 2 1/3 divided by 40?

2 answers:

7 0

Make 2 1/3 improper: 7/3. Make 40 a fraction: 40/1. Multiply 7/3 by the reciprocal of 40/1 (that means the fraction upside down: 40/1=1/40): 7/3x1/40=7/120. 2 1/3 divided by 40 is 7/120 :)

Answer:

(15x + 120) ft³

15(x + 8) ft³

Step-by-step explanation:

The prism can be decomposed into a rectangular prism and a triangular prism

The volume of the prism = volume of the rectangular prism + volume of the triangular prism

✔️Volume of rectangular prism = L*W*H

L = 5 ft

W = 4 ft

H = 6 ft

Volume = 5*4*6 = 120 ft³

✔️Volume of triangular prism = ½*b*h*l

b = x ft

h = 6 ft

l = 5 ft

Volume = ½*x*6*5 = 15x ft³

✔️Volume of the prism = (15x + 120) ft³

Explain why the point (-3,2) is diffrent from the point (2,-3)?

Georgia [21]

(-3,2) would result in the point moving over to the left and up 2. (2,-3) would be represented by going to the right 2 units, and down 3.

after hitting the black friday sales, sarah bought her dress on sale for $35. She saved 45%, what was the original cost.

8090 [49]

The original cost of the dress is $63.64

Step-by-step explanation:

After hitting the black Friday sales

Sarah bought her dress on sale for $35
She saved 45%

We need to find the original cost of the dress

The money that Sarah saved is the value of the discount on the dress

Assume that the price of the dress before the black Friday is 100%

∵ The price of the dress before the black Friday is 100%

∵ She saved 45% when she bought it the black Friday

∴ The price of the dress is decreased by 45%

∵ She bought the dress for $35 ⇒ (after discount)

Let use use the percentage method

→ Before discount : Discount : After discount

→ 100% : 45% : 55% (100 - 45)

→ x : : 35

By using cross multiplication

∵ x × 55% = 35 × 100%

- Divide both sides by 55%

∴ x = 63.64

The original cost of the dress is $63.64

4. Why studying central tendency alone is insufficient and calculating dispersion is always needed in both descriptive and infer

ira [324]

Answer:

Check below for the answer and explanation.

Step-by-step explanation:

Studying the central tendency alone is not sufficient because apart from calculating the value of the central point of a group of data ( which is what the measure of central tendency does), it is important to also understand the spread of these data about the average(mean) value.The measure of dispersion will help us to know the range of error that is recorded in both descriptive and inferential statistics and this will enable the statistician to assess the validity of the data generated from the experiment performed.

A small value of standard deviation indicates that each of the values in the dataset is close to the average (mean) value.

Find the measures of the angles in the diagram. 20 points for all of the ones listed below

Inessa [10]

AB is a diameter of the circle, so it divides circle into two semicircles.

Inscribed Angle Theorem:

The measure of an inscribed angle is half the measure of the intercepted arc.

An especially interesting result of the Inscribed Angle Theorem is that an angle inscribed in a semi-circle is a right angle. That's why m∠AQB=m∠ASB=m∠ALB=m∠ATB=m∠ARB=90°.

It is impossible to find measure of ∠BWD, its measure depends on measure of a central angle ∠WDB.
