Answer 1

Answer: 5.4

Step-by-step explanation:

Use cosine to find the adjacent side.

cosine = adjacent/hypotenuse

Substitute these values in the cosine equation:

cos(39) = x/7

7*cos(39) = x

Use a calculator to find the value of x:

x = 5.4

Jonathan is 27 years younger than Dre. Dre is two years younger than Jonathan's
age doubled. How old are Jonathan and Dre? *

Answers

Dre is 56 and Jonathan is 29

Answer:

Step-by-step explanation:

j=d-27

d=2j-2, using j from above makes this equation become

d=2(d-27)-2

d=2d-54-2

d=2d-56

-d=-56

d=56, since j=d-27

j=56-27

j=29

So John is 29 and Dre is 56

Step-by-step explanation:

all interior angles of a triangle add up to 180 degrees.

1) 46 + 67 + (4f+3) = 180

reduce:

4f+3 = 67

4f = 64

f = 16

2) 60 + 3h + 90 = 180

Is (2, -4) a solution to the inequality 2x - 3y < 15? Yes or No

Answers

Answer:

No.

Step-by-step explanation:

We substitute the values x = 2 and y = -4 into the inequality.

Left side = 2(2) - 3(-4) = 4 + 12

= 16

Now the right side is 15 so we get 16 < 15 which is incorrect.

So (2, -4) is not a solution.

Henry has a bag containing 39 letter tiles, some consonants, and some vowels. He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?

Answers

Answer:

21 consonant tiles

Step-by-step explanation:

Henry has a bag containing 39 letter tiles, some consonants, and some vowels.

He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?

Step 1

We add up the number of tiles that he pulls out of the bag

= 7 consonant tiles + 6 vowel tiles

= 13 tiles

Step 2

We divide the total number of tiles in the bag by the total number of tiles that was pulled out of the bag

= 39 tiles ÷ 13 tiles

= 3

Step 3

The most likely number of consonant tiles in Henry's bag is calculated as:

3 × The number of consonant tiles that was pulled out of the bag.

Hence:

3 × 7 consonant tiles

= 21 consonant tiles.

Therefore, the most likely number of consonant tiles in Henry's bag is 21 consonant tiles.

What is the approximate volume of this tree trunk if the circumference is 26π inches and the height of the trunk is 22 inches,

Answers

Answer:

Volume = 11680.44 cubic inches

Step-by-step explanation:

Circumference of the trunk of a tree = 2πr

Here, r = radius of the trunk

26π = 2πr

r = 13 inch

Since, volume of the cylindrical trunk = πr²h

= π(13)²(22)

= 3718π

= 11680.44 cubic inches

Answer:

22.4

Step-by-step explanation:

using altitude theorem, the height of the triangle is 20

let y = height

10/y = y/40

y² = 400

y = [tex]\sqrt{400}[/tex] or 20

Now we can us the Pythagorean Theorem to find 'x':

10² + 20² = x²

100 + 400 = x²

x=[tex]\sqrt{500}[/tex] ≈ 22.4

Answer:

Step-by-step explanation:

I think, :)

The boxplot below displays the arm spans for 44 student . The statement that is not true from the given option is

Approximately 25% of the arm spans are less than 180 cm

Option C

Given :

The boxplot below displays the arm spans for 44 students.

The five-number summary for the data is 143, 162, 168, 180, and 202.

From the given five number summary we can see that

minimum =143

First Quartile (25%)= 162

Median (50%)= 168

Third quartile (75%)= 180

Maximum =202

Now we analyze the statements

Approximately 75% of the arm spans are less than 180 cm. Its true because third quartile is 75% that is equal to 180

Approximately 50% of the arm spans are less than 168 cm.. Yes its true because median is 168

Approximately 25% of the arm spans are less than 180 cm. It is false because first quartile 25% is 162. So , 25% of the arm spans are less than 162 cm

Approximately 75% of the arm spans are greater than 162 cm. It is true . because 25% of the arm spans are less than 162 cm

Step-by-step explanation:

10 - 10 x 10

10 x -10 = -100 (always do multiplication first)

-100 + 10 = -90

Answer: The answer to this basic math question with a basic given math expression is -90.

Step-by-step explanation: Mmmm, that was super extremely easy, so anyways, here are 3 basic steps in order to evaluate the given basic math expression:

Step 1. First, let's input the original basic equation that looks in the basic equation form like this: [tex]10 - 10 * 10.[/tex]

Step 2. After we input the original basic equation, next, let's do the multiplication first by multiplying 10 by 10 that looks in the basic equation form like this: [tex]10 - 100.[/tex]

Step 3. Last but not least is after we multiply 10 by 10 first, finally, let's subtract 10 and 100, and therefore your answer to this basic math question with the given basic math expression is -90.

I hope that my full given answer with my full given step-by-step explanation is very helpful to your own basic math question with the given basic math expression, please take care, always be safe, and have a great rest of the holiday winter break, Merry Christmas and a happy new year! :D
