Little triangle first - hypotenuse is 4, now we used this info help us find the opposite.

Opposite & Hypotenuse - Sin

Sin(45) = O/H

Sin(45) = O/4

x 4 both sides, to get Opposite

Opposite = 4 x Sin(45)

= 2 root 2

= 2.8284.......

Big Triangle next,

Opposite is 2.8284......

Y is the adjacent

Opposite & Adjacent - Tan

Tan (30) = O/A

Tan(30) = 2.8/A

x A

A x Tan(30) = 2.8

÷Tan(30)

A = 2.8 ÷ Tan(30)

A= 2 root 6

A= 4.8989...

So, y is 5 to 1 significant figure

Or

Y = 4.9 to 1d.p

(Haven't rounded anything in my calculation, even though it's shown that way, in my workings. So, you can follow along)

Hope this helps!

For a certain triangle ABC, if a line intersects AC at D, intersects AB at E, and is parallel to CB, would the proportion AE | AD = EB | DC be accurate? Explain your answer.​

Answers

The given proportion of triangle ABC as AE/AD = EB/DC is; Not Accurate

Understanding Basic proportionality theorem(Thale's Theorem)

This theorem states that If a line is drawn parallel to one side of a triangle, then it cuts other two sides proportionally.

Thus, In ΔABC, DE || BC

By Thales theorem, we can say that;

AD/DB = AE/EC

Rearranging we can arrive at;

AE/AD = EC/DB

When we simplify further by adding 1 to both sides, we will get;

AD/AB = AE/AC

Thus, the given proportion is not accurate

Answers

Given :-

To Find :-

A equivalent expression .

Solution :-

The given expression is ,

→ 5³ .

As we know that if there is aⁿ , where n is the power then we have to multiply the number at the base n times . Hence here ,

→ 5³ can be rewritten as

→ 5 * 5 *5

Simplify ,

125

Hence the required answer is 125 .

I hope this helps.

Let us evaluate

Explanation:

[tex]5³ = 5 × 5 × 5 = 125[/tex]

can also be understood as 5 cubed.

Whenever a number (x) is multiplied by itself three times, then the resultant answer is known as the cube of that number.

Thus, 5 to the 3rd power is equal to 125

Will there ever be an
age, other than 14 and
7, where Pedro is twice
as old as his brother?
Explain.

Answers

Answer:

No

Step-by-step explanation:

They are 7 years apart. Therefore, the only age where Pedro will be twice as old is his brother is the age 14 because 7 is half of 14.

Hi!

Your answer is No.

This is because they are seven years apart in age. The only way for Pedro to be twice as old as his brother would be for

a + 7 = 2a

('a' is Pedro's brother's age)

Now, if we subtract a from both sides in the top equation, we get:

7 = a

What is the exact value of 5 5/6- (1 1/4 +3 7/8)


Answers

Answer:

15/40 which simplified is 3/8

Step-by-step explanation:

To solve this equation, we first have to turn all mixed numbers into improper fractions so we can add and subtract them

When we do this we get, 35/5 - (11/4 + 31/8)

Since there is a negative (-) sign before the parentheses, we automatically sub in a -1 in there and we distribute

Now we have 35/5 - 11/4 - 31/8

We can’t subtract this directly since they all have different denominators, so we have to change them to a common denominator

The common denominator of 5 4 and 8 is 40 so we multiply both the numerators and denominators by whatever number it is so the denominators are 40

This gets us to 280/40 - 110/40 - 155/40

When we subtract all of this, we get…

15/40 which can be simplified to 3/8

what is the smallest possible average of five distinct positive even integers

Answers

Answer:

2+4+6+8+10/5

10 is average of this

The smallest possible average of five distinct positive even integers is 6.

To find the smallest possible average of five distinct positive even integers, to minimize the values of those integers.

The smallest distinct positive even integers start from 2, 4, 6, 8, 10, and so on.

To minimize the average, to choose the five smallest even integers. So, the five distinct positive even integers are:

2, 4, 6, 8, 10

To calculate the average, sum up these five integers and divide by 5:

Average = (2 + 4 + 6 + 8 + 10) / 5

Average = 30 / 5

Average = 6

So, the smallest possible average of five distinct positive even integers is 6.
