(8)can someone please explain this

Answer:

12.2 mi

Step-by-step explanation:

We need to use the Pythagorean theorem, we can use the equation A^2 + B^2 = C^2 then get the square root of the answer

plugging in the numbers with the equation we get the equation:

10.6^2 + 6.1^2 = c^2

then we multiple the available numbers by their exponents we get:

112.36 + 37.21 = c^2

Adding the numbers together we get:

112.36 + 37.21 = 149.57

Get the square root of 149.57 (Since the earlier equation was just everything squared) we get:

12.2298814385

Round it to the nearest tenth as directed, then we get:

12.2

The answer is 12.2 mi

x² = (10,6)² + (6,1)²

x² = 112,36 + 37,21

x² = 149,57

x = 12,22mi✔

No, they are opposite as squared is multiplication. Please give brainliest!

Answer:

x = 90

Step-by-step explanation:

- [tex]\frac{8}{9}[/tex] x - [tex]\frac{4}{45}[/tex] x + [tex]\frac{1}{5}[/tex] x = - 70

Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions

- 40x - 4x + 9x = - 3150 , that is

- 35x = - 3150 ( divide both sides by - 35 )

x = 90

Hello there!

The right prime factorization is

2*2*2*3*11 because 2 and 3 and 11 are prime.

Take a look at the words "prime" and "factorization"

Can you see something that looks like "prime factors?" Exactly!

2 is prime. 3 is prime. 11 is also prime.

A prime number is only divisible by 1 and itself.

What is the value of 5+2*15+(12*4)?

If you remember "Please Excuse My Dear Aunt Sally" that's great as long as you know what that means.

P = Parentheses

E=Exponents

M=Multiplication

D=Division

A=Addition

S=Subtraction

5+2*15+(12*4)=5+2*15+(48)=5+30+48=83

A farmer has 40 tomatoes in a basket. 18 were green. How many were red?

[tex]Given:[/tex]

18 green

40 total

[tex]Find:[/tex]

Red

40-18=22

Hope this helps

Answer:

18 green

40 total

Red

40-18=22

Answer:

Step-by-step explanation:

The probability can be expressed as a number between 0 and 1 or a percent value between zero and 100%.

Correct choice is:

Answer:

45 lawns

Step-by-step explanation:

If you subtract 60-15 it will give you 45

Answer:

it's the 0-7

Step-by-step explanation:

because all of the numbers are negative and if you have negative and positive numbers the product will just be positive

I see you need help with 14 - 23 evens, so hopefully this is what you need. If not, comment and I will edit it as appropriate :) Have a nice day

14: It is slightly hard to see, but I am going to say 15 mm. We can decide this because the ruler says it is in mm and on both sides are 10 and 20. It is in the middle so we will decide the answer is 15.

16: 3,629 - 429 = 3,198 (not much explanation, just use a calculator or do the subtractation)

18: 491 * 700 = 343,700 (multiply 491 * 7, then add the two zeros onto the end of the answer because it's 700, not 7)

20: 5n = 3,175 ; n = 635 (divide both sides of the equation by 5)

22: See pictured below

After that, 2/3 is equal to 0.66666666666, which we can round to 67%

Even though it is not an even, you said "14 - 23" so here is 23 as well:

230, 240, 250, 260, 270, etc

                       /\

                    256 is inbetween here

It is above 5, so the answer is C 260

Answer:

[tex]{ \rm{3 {x}^{2} + 2x - 4 = 0 }}[/tex]

• let's use the quadratic formular to solve the quadratic equation given.

• Considering general quadratic equation; ax² + bx + c = 0

• therefore;

[tex]{ \tt{x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} }} \\ [/tex]

• substitute following the mathematical operation rules:

[tex]{ \rm{x = \frac{ - 2 \pm \sqrt{ {2}^{2} - (4 \times 3 \times - 4) } }{(2 \times 3)} }} \\ \\ { \rm{x = \frac{ - 2 \pm52}{6} }} \\ [/tex]

• split the values:

[tex]{ \rm{either \: \{x = \frac{ - 2 + \sqrt{52} }{6} \} \: \: or \: \: \{x = \frac{ - 2 - \sqrt{52} }{6} \} }} \\ \\ { \rm{either \: \{x = 0.87 \} \: \: or \: \: \{x = - 1.54 \}}}[/tex]

Answer:

33. x=4

This is because 2 and 14 equal 16 which is divided by 4 to sove for x. that is why that equals 4.

36. 60 degrees

180 divided by the 3 angles a triangle has equals 60.

Answer:

33. 4x=2+14

4x= 16

4x/4= 16/4

x= 4

36. 180° = the sum

to find one angle 180/3 since they're 3 angles in a triangle

180/3= 60°

Answer:

its side angle side

Step-by-step explanation:

the sides are equal and the angle in between is the same

Answer:

26.5 miles.

Step-by-step explanation:

Given: Time for running Boston Marathon= 2.12 h

Speed= 12.5 mph

Distance covered in Boston Marathon  

Distance covered= speed x time  

Distance covered = 12.5 x 2.12=26.5 miles  

∴ Distance covered in the Boston Marathon is 26.5 miles.

Answer:

26.5

Step-by-step explanation:

You have two numbers. Do you think you should  add, multiply, substract, or divide..?

Multiply, 2.12 x 12.5 on paper or a calculator and you will get 26.5.

115+65 = 180

Answer:

x = 0

y = 1

Step-by-step explanation:

2x + 3y = 3               Multiply this equation by 3

3x + 5y = 5               Multiply this equation by 2

3(2x + 3y = 3)

6x + 9y = 9

2(3x + 5y = 5  )

6x + 10y = 10             Notice the xs are the same.

6x + 9y = 9

6x + 10y =10            Subtract

     - y = - 1                Multiply each side by -1

     y = 1

2x + 3y = 3

2x + 3*1 = 3

2x = 0

x =0

[tex]35x( \frac{3}{7} = \frac{1}{5} + \frac{1}{x} ) \\ = > 35x \times \frac{3}{7} = > 35x \times \frac{1}{5} + 35x \times \frac{1}{x} \\ = > 5x \times 3 = 7x + 35 \\ = > 15x = 7x + 35 \\ = > 15x - 7x = 35 \\ = > 8x = 35 \\ = > x = \frac{35}{8} \\ = > x = 4.375[/tex]
