Mathematics
1 answer:
Mariana [72]3 years ago
4 0

Answer:

12

Step-by-step explanation:

We know that AD=BC and that AB=CD. We also know the perimeter of the rectangle ABCD to be 54 units.

From this, we can add up the sides which will be equal to 54 units.

AD+BC+AB+CD=54

2x+2x+3x-3+3x-3=54

10x=60

x=6

Since we are trying to find the length of side BC we substitute this value back into 2x.

BC=2x =2*6=12

Therefore, the length of BC is 12 units.

Why people hate math? And what describes people how they like math
Dmitrij [34]

What do you think of when you think of maths? If you're like most people, it's probably something like: numbers, equations, boredom, anxiety and pain.

Then there are the weird ones, like me, who call themselves mathematicians. When we think of maths, we think of shapes, colours, patterns, creativity, freedom, insight and the feeling of making deep connections.

Why is there such a huge gap between how mathematicians and the general population see and experience maths?

The myth of the maths gift

So many people give up on engaging with maths from a young age, deciding, "I am just not a maths person, I'm not good at maths."

There is a deeply entrenched view in our society that ability to learn and master mathematical understanding comes from an inborn gift rather than from hard work and perseverance.

When we hold this view from a young age, the maths classroom becomes a place where we are constantly being judged not good enough, a place of repeated failure and shame.

And with each failed test, with each time we're put on the spot to answer a question we're not prepared for, we think, "See, I'm really not a maths person. Get me out of here, I don't belong."

Then grows maths anxiety.

The work of academics like Carol Dweck and Jo Boaler of Stanford University suggests that the strongest predictor of achievement in maths is mindset—specifically, whether you believe you can grow your maths ability or whether it is fixed.

Come again? You're saying I just have to believe I'm good at maths and then I can be?

Not quite.

A circle fountain has a radius of 9.4 feet . What's the fountains diamiter
boyakko [2]
<h3>Answer:</h3>

18.8 feet

<h3>Step-by-step explanation:</h3>

We are given;

Radius of the fountain is 9.4 feet

We are required to determine the diameter of the fountains

We need to know that the diameter of a circle is twice the radius of the circle.

That is;

Diameter = 2r

Therefore;

Diameter of the fountain = 2 × 9.4 feet

                                         = 18.8 feet

Thus, the diameter of the fountain is 18.8 ft

A town planner wants to build two new streets, Elm Street and Garden Road, to connect parallel streets Maple Drive and Pine Aven
Advocard [28]

Answer:

72°

Step-by-step explanation:

From the information given:

A town planner wants to build two new streets, Elm Street and Garden Road, to connect parallel streets Maple Drive and Pine Avenue.

We are also told that there is a  Trapezoid EFGH with EH as the Pine avenue and EF as the Elm street.

However, side FG and EH are parallel.

∠G = 108°

From the property of parallel lines :

since FG || EH

Then  ∠G = ∠H  = 108°  (i.e corresponding angle will also be equal)

The required angle between Elm Street and Pine Avenue would be interior angles +  180°  given that  alternate angles are also equal.

The required angle between Elm Street and Pine Avenue = 180° - 108°

The required angle between Elm Street and Pine Avenue = 72°

In its monthly report, the local animal shelter states that it currently has 24 dogs and 18 cats available for adoption. Eight o
andrezito [222]

Answer with Step-by-step explanation:

We are given that

Total dogs=24

Total cats=18

Total animals=24+18=42

Male dogs=8

Male cats=6

Total male animals=8+6=14

Total female animals=42-14=28

Female cats=18-6=12

Dogs female=24-8=16

a.We have to find the probability that the pet is male, given that it is cat.

It means we have to find P(Male/cat)  

Conditional probability: P(A/B)=\frac{P(A\cap B)}{P(B)}

P(Cat)=\frac{18}{42}

P(male cat)=\frac{6}{42}

P(Male/cat)=\frac{\frac{6}{42}}{\frac{18}{42}}

P(male/cat)=\frac{6}{18}=0.33

b.P(female cat)=\frac{12}{42}

P(female)=\frac{28}{42}

P(Cat/Female)=\frac{\frac{12}{42}}{\frac{28}{42}}=\frac{12}{28}=0.43

c.P(Dog)=\frac{24}{42}

P(dog female)=\frac{16}{42}

P(female/dog)=\frac{\frac{16}{42}}{\frac{24}{42}}

P(female/dog)=\frac{16}{24}=0.67
