gary has two ladders for a project one reaches 16 3/7 while the other reaches 12 /5/7 how much higher can the longer ladder reach

Answers

Answer 1

The longer ladder can reach 3 8/7 feet higher than the shorter one.

The Proportionality Theory.The longer ladder can reach 4 2/7 feet higher than the shorter ladder. To calculate this, we need to subtract the shorter ladder's height (12 5/7 feet) from the taller ladder's height (16 3/7 feet).We can represent this calculation with a fraction equation, as follows:[tex]\frac{16 \frac{3}{7}}{12 \frac{5}{7}} - 12 \frac{5}{7} = \frac{4 \frac{2}{7}}{1}[/tex]To solve this equation, we first need to convert the fractions into equivalent fractions with a common denominator. In this case, the denominator is 7. This means that the first fraction becomes 16 3/7, the second fraction becomes 12 5/7, and the third fraction becomes 4 2/7.Once we have the fractions in the same denominator, we can now subtract the shorter ladder's height (12 5/7 feet) from the taller ladder's height (16 3/7 feet). This gives us a result of 4 2/7 feet. This means that the longer ladder can reach 4 2/7 feet higher than the shorter ladder.To put this into perspective, if we were to use the ladders to reach a height of 16 3/7 feet, the shorter ladder would only reach 12 5/7 feet, while the longer ladder would reach 16 3/7 feet. This means that the longer ladder can reach 4 2/7 feet higher than the shorter ladder.

In a school, 10% of students have 7 ball pens, 30% of students have 3 ball pens, 40% of students have 2 ball pens and 20% of students have 1 ball pens. What is the expected number of ball pens of a student?

Answers

The expected number of ball pens of a student is 2.4.

What is the expected number?

In statistics and probability analysis, the expected value is calculated by multiplying each of the possible outcomes by the likelihood that each outcome will occur and then summing all of those values.

The expected number of ball pens of a student can be calculated by taking a weighted average of the number of ball pens that each group of students has.

The weight for each group is the percentage of students that are in that group.

So, we can calculate the expected number of ball pens of a student by:

(10% * 7) + (30% * 3) + (40% * 2) + (20% * 1)

0.7 + 0.9 + 0.8 + 0.2

The expected value is also known as the population means and it can be calculated by summing the product of each outcome’s probability and its corresponding value.

Here, the outcome is the number of ball pens.

Hence, the expected number of ball pens of a student is 2.4.

If a trapezoid has an area of 135cm^2 and it’s height is 10cm and one base is 12 cm, find the other base length.




thxxx <333

Answers

The length of other base  is 15 cm.

The area of a trapezoid can be found by using the formula:

Area = (b1+b2) * h / 2 where b1 and b2 are the lengths of the bases, and h is the height.

Given that the area of the trapezoid is 135 cm^2, the height is 10 cm, and one base is 12 cm, we can substitute these values into the formula to find the length of the other base.

Area = (b1+b2) * h / 2 = 135cm^2

We can solve for the other base length by isolating b1

b1 = 2*Area/h - b2

b1 = 2*135/10 - 12 = 27 - 12 = 15

So, the other base length is 15 cm.

Therefore, The length of other base  is 15 cm.

The measure of angle B is 107°.

What do similar triangles mean?

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.

Given a triangle, NPZ is similar to triangle HBZ.

Which can also be written as ΔNPZ ≈ ΔHBZ

So, by equating the corresponding angles that are angle P = angle B:

8x-37°=180-(2x-5+42)°

10x=180

x=18°

So, H=36-5=31°

Since the sum of all angles in a triangle is 180°, angle B can be calculated  as

What is Bisection?

Bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector.

An angle bisector divides an angle into equal angles. If the angle is , the two angles made will be (p/2)°. This angle bisector passes through the vertex of an angle.

Example: Consider an Angle ∠ABC = 90°. An angle bisector will cut it into two equal angles of 45° each.

Given, AD bisects ∠BAC

MP = 20

DC = 31

∠BAD = 28°

AD bisects ∠BAC

⇒ ∠BAD = ∠DAC

⇒ ∠DAC = 28°

∠BAC = ∠BAD + ∠DAC

∠BAC = 28° + 28°

∠BAC = 56°

Since, In a figure, sides opposite to the equal angles are also equal

∠BAD = ∠DAC

⇒ BD = DC

⇒ BD = 31

⇒ BD = 31

By the figure,

∠MAP = ∠BAD and ∠PAL = ∠DAC

⇒ ∠MAP = ∠PAL

⇒ MP = PL

As an illustration, a proportion is written as a: b = c: d.

Solution:-

(a+b+c)(a-b+c)=a2+b2+c2 prove

Answers

Answer:

There might be an error in the question, the result below should be the correct answer. It is not possible for a^2+b^2+c^2 to be the answer.

(a+b+c)(a-b+c) = a^2 +2ac - b^2 + c^2

Step-by-step explanation:

(a+b+c)(a-b+c) = a^2 - ab +ac + ba - b^2 +bc + ca - cb + c^2 (expanding the two terms in brackets first)

Since ab = ba, ac = ca and bc = cb,

-ab and ba can be cancelled out

bc and -cb can be cancelled out

Hence, (a+b+c)(a-b+c) = a^2 +2ac - b^2 + c^2

This is what I have obtained through expansion, then simplification by cancelling out the common terms.

Jay and kevin are shoveling the snow off a driveway. working together, they can clear the driveway of snow in 14 minutes. working alone, it would take kevin 21 minutes longer to clear the driveway of snow than it would take jay working alone. when j is the number of minutes it would take jay to clear the driveway of snow when working alone, the situation is modeled by this rational equation: how long would it take jay to clear the driveway of snow working alone?
a. 7 minutes
b. 21 minutes
c. 35 minutes
d. 42 minutes

Answers

Therefore, As a result, the answer to the given equation problem is Jay would need to work alone for 21 minutes to remove the snow from the driveway.

Define equation .

A number, a variable, or a mix of both plus certain operation symbols make up an expression. An equal sign separates two expressions that make up an equation. Word illustration The product of 8 and 3 is 11.

Here,

The formula is: 1/j +1/j+ 21 = 11/ 4.

LCM = j+21+j / j(j+21)=1/14

Thus, 2j+21 / j(j+21) = 1/14 is obtained.

14(2j+21) times itself yields j(j+21).

28j+294 expanded to j²+21j

Gather comparable terms

j²+21j-28j-294=0

j²- 7j-294=0

With the use of a graphing calculator, we have:

j = 21 or j= -14

Due to the context,

j's value cannot be negative.

As a result, the answer to the given equation's problem is Jay would need to work alone for 21 minutes to remove the snow from the driveway.

Read the following article and answer the question that follows:US Surgeon General Says More Needed to Curb Teen Smokingby CAROL PEARSON on MARCH 9, 2012Cigarette smoking is the leading cause of preventable death in the United States and throughout the world, according to the U.S. Centers for Disease Control and the World Health Organization. In the United states, the federal government has led anti-smoking campaigns for more than 40 years. But according to a new report from the U.S. Surgeon General, the nation's top health official, progress in preventing American teenagers and young adults from using tobacco has stalled.The report is a tome - nearly 900 pages long. Its focus is on how to prevent tobacco use among teenagers and young adults.Smoking Among Teens UpWhile the overall rate of tobacco use has drastically declined since the first surgeon general's report more than 40 years ago, this report shows that children as young as 10 are developing a deadly tobacco addiction. Surgeon General Regina Benjamin says the statistics are shocking. "Every day 1,200 Americans die from smoking. And each of those people are being replaced by two young smokers," she stated. The goal is to end tobacco use among teens and young adults. Studies show that teenagers are much more vulnerable than adults to the addictive properties of nicotine, a drug found naturally in tobacco. And that tobacco use interferes with lung development.More than 90 percent of adult smokers lit up their first cigarette before they turned 18. Many start the habit when they are in middle school, between 11 and 13 years old. "Today, more than 600,000 middle school students smoke, and three million high school students smoke cigarettes," Benjamin explained.Studies also show that more than one in three young adults between the ages of 16 and 26 smoke. On the other hand, fewer than one percent of smokers start after the age of 26. Anti-Smoking Campaign for YouthDr. Benjamin outlined plans to launch a media campaign like this one aimed at youth. "I want our next generation to be tobacco-free," she said. "That's the goal, to have our next generation tobacco free."Dr. Benjamin wants to involve parents and teachers and to refocus on community anti-smoking programs, including programs in schools.Ads Targeting Teens, Tobacco Mimic CandyThe report criticizes tobacco companies for advertising campaigns that target young people and for making products like tobacco candy.It cites the effectiveness of placing higher sales taxes on tobacco products, which make them too costly for most teens to buy.A U.S. Health Department spokesman said helping young people avoid tobacco addiction will cut the number of tobacco-related illnesses and premature deaths and spare more families the devastating emotional toll.The author's purpose in the article is to ____________?A express the thoughts of the doctors involved in the studyB show the reader how to stop smokingC inform the reader about the need for taking action against teenage smokingD persuade teenagers to avoid developing the habit of smokingF shock the reader with alarming facts about smoking POURQUOI PEUT ON PARLER DE CONTE PHILOSOPHIQUE A PROPOS DU LIVRE TOUT VA POUR LE MIEUC DE ALAIN MONNIER Two angles are vertical angles.
