its pretty easy

Answer:

the answer is A your welcome

Step-by-step explanation:

Answer:

2(x+10) = 3x-30          (reason: vertical angles are congruent)

2x+20 = 3x-30

20 = 1x-30

1x = 20+30

1x = 50

x = 50

Answer:  46.4

Step-by-step explanation:

[tex]F=\frac{9}{5}C + 32\\[/tex]

[tex]F=\frac{9}{5}(8) + 32\\[/tex]

[tex]F=\frac{72}{5} + 32\\[/tex]

[tex]F=\frac{72}{5} + \frac{160}{5} \\[/tex]

Answer:

x = 9

m<AOB = 29°

m<BOC = 57°

m<COD = 29°

Step-by-step explanation:

Given:

m<AOB = (4x - 7)°

m<BOC = (5x + 12)°

m<COD = (2x + 11)°

The diagram shows <AOB is congruent to <COD.

Set both angles equal to each other to find x.

m<AOB = m<COD

4x - 7 = 2x + 11

Collect like terms

4x - 2x = 7 + 11

2x = 18

Divide both sides by 2

2x/2 = 18/2

x = 9

Find the measure of each angle by plugging in the value of x into each expression for each angle:

m<AOB = (4x - 7)° = 4(9) - 7 = 36 - 7 = 29°

m<BOC = (5x + 12)° = 5(9) + 12 = 45 + 12 = 57°

m<COD = (2x + 11)° = 2(9) + 11 = 18 + 11 = 29°

The population of a city increased from 805,743 in 1995 to 1,013,751 in 2005.

Percent of Change:

Increase divide by Original times 100

Solve:

1,013,751 - 805,743  = 208,008

208,008 ÷ 805,743 × 100

Step-by-step explanation:

What are acute angles?

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:

An acute triangle.

Step-by-step explanation:

· In these angles, they are all less than a 90 degree angle(right angle) which we would infer an acute triangle.

Answer:

think about what is in between 4 and 4.5

you could put 4.4, 4.3, 4.25, 4.1 etc.

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]-9x + y = 3\implies y = \stackrel{\stackrel{m}{\downarrow }}{9} x +3 \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so then

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {9\implies \stackrel{slope}{\cfrac{9}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{9}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{9}}}[/tex]

so we're really looking for the equation of a line whose slope is -1/9 and passes through (-9 , -1)

[tex](\stackrel{x_1}{-9}~,~\stackrel{y_1}{-1})\qquad \qquad \stackrel{slope}{m}\implies -\cfrac{1}{9} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-1)}=\stackrel{m}{-\cfrac{1}{9}}(x-\stackrel{x_1}{(-9)}) \\\\\\ y+1=-\cfrac{1}{9}(x+9)\implies y+1=-\cfrac{1}{9}x-1\implies y=-\cfrac{1}{9}x-2[/tex]

The amount of wheat exported in Canada is 2.6 x 10 tons per year.

Standard form is used to transform large numbers into smaller number. In order to write a number in standard form, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

For example: the number 1 x 10² is equivalent to 100

2.21 x 10^7 ÷ 8.5 x 10^5 = 0.26 x 10^2 = 2.6 x 10

Answer: 27

Step-by-step explanation:

By the order of operations, we should first calculate the expression in the parentheses:

= 3 - 4 (- 6)

Next, we calculate the expression being multiplied:

= 3 + 24

Lastly, we add the two terms:

= 27

Using the given order operations to solve for the given operation, we have the answer as; 27

We are given the expression;

3 - 4(-2 - 4)

From mathematical operation acronym titled BODMAS, we need to first solve what we have in the bracket and so we get;

3 - 4(-6)

Secondly we multiply out the bracket to get;

3 + 24

We now add to get 27

Answer:

48.6 tablespoons

Step-by-step explanation:

If for every kg of flour 3.6 (3 3/5) tablespoons are used, then for 13.5 (13 1/2) kgs: 3.6 × 13.5 = 48.6 tablespoons are used.

From the question,

[tex]3\frac{3}{5}[/tex] tablespoons of melted butter = 1 kilogram of flour

The number of tablespoons of melted butter the baker can use for 13 kilograms of flour is calculated as

1 kilogram of flour =  [tex]3\frac{3}{5}[/tex] tablespoons of melted butter

[tex]13\frac{1}{2}[/tex] kilograms of flour = b

Cross multiply

1 kilogram of flour x b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter

b = [tex]13\frac{1}{2}[/tex] kilograms of flour x [tex]3\frac{3}{5}[/tex] tablespoons of melted butter  /1 kilogram of flour

b = 48.6 tablespoons of melted butter

Therefore, the baker would use 48.6 tablespoons of melted butter for [tex]13\frac{1}{2}[/tex]kilograms of flour.

Choice A describes a function

Step-by-step explanation:

Relations and Functions

A relation is a set of inputs and outputs with no restrictions. A function is a relation with one output for each input.

This means that if at least one input has more than one output, it's not a function.

Analyzing each choice:

A: It can be noted that each input (2,-2,0,-3) has only one output. Thus this set describes a function.

B: Input 1 has two outputs (5,6), thus this is not a function.

C: Input 6 has two outputs (-4,-1), thus this is not a function.

D: Input 2 has two outputs (7,2), thus this is not a function.
