how many groups of 10 are there in 230?​

Answer:

13

Step-by-step explanation:

Simplify both sides of the equation.

(Combine Like Terms)

Step 2: Add 3 to both sides.

4x−3+3=49+3

4x=52

Step 3: Divide both sides by 4.

Answer:

Exact Form: x ≈ − 1 2 , 1.04081022

Decimal Form: x ≈ − 0.5 , 1.04081022

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

Answer:

40

Step-by-step explanation:

AFE=120 so arc AE is also 120

those 3 angles add up to 180 and 180-120-20=40

The measure of ∠C is 40°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Angle measure of central angle is equals to measure of intercepted arc.

External angle formed outside a circle,

= Half the difference of the major and minor arc =

Angle measure of AFE

= arc AE = 120°

Thus:

m∠C = 1/2(120 - 40)

m∠C = 40°

So, the angle measure of C is 40°

Therefore, 40° is the measure of ∠C.

Answer:

[tex]m=665+4h[/tex]

Step-by-step explanation:

Profits of the local bakery is given by

[tex]P=m-(250+4h)[/tex]

where

m = Amount of money to be received

P = Profit

h = Number of hours worked

Now P = $415

So,

[tex]P+(250+4h)=m\\\Rightarrow m=P+250+4h\\\Rightarrow m=415+250+4h\\\Rightarrow m=665+4h[/tex]

The equation to calculate the amount of money, m, the bakery should receive if the desired profit is $415 is [tex]m=665+4h[/tex].

Answer: Perpendicular lines

Step-by-step explanation:

The first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.

The two equations, y - 2 = x + 20 and y - 2 = -(x + 20), represent linear equations in standard form. Let's break down each equation:

y - 2 = x + 20

This equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the value of x plus 20. This equation can be rearranged to slope-intercept form (y = mx + b) by isolating y:

y = x + 20 + 2

y = x + 22

The equation y = x + 22 represents a line with a slope of 1 and a y-intercept of 22.

y - 2 = -(x + 20)

Similarly, this equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the negative of the value of x plus 20. This equation can also be rearranged to slope-intercept form by isolating y:

y = -(x + 20) + 2

y = -x - 20 + 2

y = -x - 18

The equation y = -x - 18 represents a line with a slope of -1 and a y-intercept of -18.

In summary, the first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.

Answer:

The equation is = I = [tex]e^{4.8}[/tex]

Step-by-step explanation:

As given ,

M - magnitude of an earthquake

I - intensity of earthquake

I₀ - intensity of a reference earthquake

The relation between the three is as follows :

M = log([tex]\frac{I}{I0}[/tex] )

As given -

M = 4.8,  I₀ = 1

⇒ 4.8 = log([tex]\frac{I}{1}[/tex]) = log(I)

⇒ 4.8 = log(I)

⇒I = [tex]e^{4.8}[/tex]

So, the equation becomes I = [tex]e^{4.8}[/tex]

Answer:

c = 82 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

c² = 18² + 80² = 324 + 6400 = 6724 ( take the square root of both sides )

c = [tex]\sqrt{6724}[/tex] = 82

substitute

Lx(2L-6)=78

2L^2-6L=78

2L^2-6L-78=0

factor

(2L-15.86)(L+4.95)=0

2L=15.88, L=7.94

Answer:

y= -6x/13 -10/13

Step-by-step explanation:

first you'll subtract 6x from both sides

6x+13y=-10

-6x .      -6x

13y=-6x-10

then you divide by 13 to get y by itself

y= -6x/13 -10/13

Answer:

y = -6/13х - 10/13

Step-by-step explanation:

6x +13y = -10

Subtract 6x from both sides to isolate y:

13y = -6x - 10

Divide both sides by 13:

y = -6x/13 - 10/13
