Answer:

 NO = 10

Step-by-step explanation:

The segment addition theorem tells you ...

 MN + NO = MO

Substituting the given expressions for these lengths, we have ...

 x + 5x = 3x+6

 3x = 6 . . . . . . . . . subtract 3x

 x = 2 . . . . . . . . . . divide by 3

We can use this value to find the length NO:

 NO = 5x = 5(2) . . . . substitute for x

 NO = 10

Answer:

h²= G²- R²

h² = 10²-6²

h²= 100 - 36

h²= 64

h = √64

.............

Heya!

Answer:

h = √91 cm

Step-by-step explanation:

Apply pythagorean theorem, a² + b² ° c².

Where,

a = ½(6) = 3 cm

b = h

c = 10 cm

Plug in the values

3² + h² = 10²

9 + h² = 100

9 + h² - 9 = 100 - 9

h² = 91

h = √91 cm

Answer:

(-2 ,5) see picture

Step-by-step explanation:

y= -4x + 2

x=-y/4+1/2

If 10p4₅ = 134₁₀, then p is such that

[tex]10p4_5 = 1\times5^3 + 0\times5^2 + p\times5^1+4\times5^0 \\\\ \implies 134 = 125 + 0 + 5p + 4[/tex]

Solve for p :

134 = 129 + 5p

5 = 5p

p = 1

Answer:

P=21

Step-by-step explanation:

P=a+b+c=6+7+8=21

Answer:

P= b+8

P= a+b+c

P= 6+4+b -2

P= 10-2+b

P= 8+b

P= b+8

(1) Combining fractions is just a matter of writing each individual fraction in terms of a common denominator. The least common multiple of 6, 4, and 8 is

LCM(6, 4, 8) = 24

since 6×4 = 4×6 = 8×3 = 24. So

2/6 = (2×4)/(6×4) = 8/24

1  1/4 = 4/4 + 1/4 = 5/4 = (5×6)/(4×6) = 30/24

13  4/8 = 104/8 + 4/8 = 108/8 = (108×3)/(8×3) = 324/24

Then

2/6 + 1  1/4 + 13  4/8 = 8/24 + 30/24 + 324/24 = 362/24 = 181/12

(2) We have

LCM(12, 9) = 36

since 12×3 = 9×4 = 36. Then

121  2/12 = 1452/12 + 2/12 = 1454/12 = (1454×3)/(12×3) = 4362/36

781  6/9 = 7029/9 + 6/9 = 7035/9 = 2345/3

Answer:

  x +4y = -5

Step-by-step explanation:

The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.

  3x +12y = 3(-5) +12(0)

  3x +12y = -15

We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:

  x + 4y = -5

Answer:

2:1.

Step-by-step explanation:

The area of a red  curved surface = 2πr^2.

The area of the yellow flat surface = πr^2.

This is the case for all the hemispheres.

Therefore the  required  ratio =  2πr^2 :  πr^2

= 2:1.

Answer:

10,582 pieces of candy.

Step-by-step explanation:

1 jar contains 286 pieces

Therefore, 37 jars contain:

37 × 286

= 10,582 pieces of candy.

Answer:

10,582 pieces of candy behind the counter

Step-by-step explanation:

multiply 37 by 286 and you get 10,582

Answer:

1 =b

Step-by-step explanation:

8 = b - 1 + 8b

Combine like terms

8 = 9b -1

Add 1 to each side

8+1 = 9b-1+1

9 = 9b

Divide each side by 9

9/9 = 9b/9

1 =b

Answer:

1

Step-by-step explanation:

Group like terms

8b + b = 8+ 1

simplify each sides

9b = 9

divide both sides by 9

9b÷9 = 9÷9

cancel out

answer is equal to 1

b = 1

Answer:

A.34

Step-by-step explanation:

f(4)=17

2f(4)=34

if I've understood it :/ but I've didn't understood about g(x)

Answer:

A. 34

Step-by-step explanation:

f (x) = x² + 1. f (4) simply means we should replace X with 4

so it will be

f (4) = 4² + 1

= 16 + 1

= 17

so now 2. f ( 4) means:

2. 17

which gives :

34

Answer:

decay

Step-by-step explanation:

The function is in the form

y = a (b)^x

a is the initial value and b is the growth or decay factor

When b < 1  it is decay

When b > 1 it is growth

Since b = .93 it is decay

Answer:

Answer:

-36

Step-by-step explanation:

We have the equation 4 lm - nl , along with the values, m is equal to -7 and n is equal to 2.

To solve, we need to only substitute the values of each variable into the original equation :

4 |-7 - 2|

First solve the equation within the absolute value, any value that comes out of those brackets become positive :

|-7 - 2|

|-9|

4|-9|

4(-9)

Now multiply to get our answer:

4(-9)

-36

The numbers less than 30 that are diviisible by 8 are,

24, 16, 8

i think this is all because these are the only numbers 8 can divide into to get a whole number.

Answer: x = 30°

Concept:

Here, we need to know the idea of an isosceles triangle and the vertical angle theorem.

An isosceles triangle is a triangle that has any two of its sides equal to each other. Also, the angles opposite these equal sides are equal, which is basically the base angles.

The vertical angle theorem states that two vertical angles formed when two lines intersect each other are always equal to each other.

Solve:

Find the other base angle of the isosceles triangle.

Since there are two equal sides, we know that this is an isosceles triangle.

Since the definition said that the base angles are equal, the other base angle would also be x.

Find the value of x

According to the vertical angle theorem, two vertical angles formed by intersection are equal.

Just as angle x and 30°, are vertical angles formed by intersection, therefore, [tex]\boxed{x=30}[/tex]
