Step-by-step explanation:

For #3 a given statement should typically be together so this is strange.

40%

We get: 40% of 30 is 12.

Is this true?

Yes! 40% of 30 = (0.4)(30) = 12

Answer:

<3 = 50

Step-by-step explanation:

The sum of the angles of a triangle is 180

<1 + 40 + 90 = 180

<1 + 130 = 180

<1 = 50

<1 and <3 are vertical angles and vertical angles are equal

48=y+5y

pretend that there is a 1 in front for the y

48=1y+5y

add the like terms first

1y+5y=6y

48=6y

divide both sides by 6 to get y by itself

48/6=6y/6

8=y

answer:

y=8

Answer:

y = 8

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

48 = y + 5y

Step 2: Solve for y

Step 3: Check

Plug in y into the original equation to verify it is a solution.

Here we see that 48 does indeed equal 48.

∴ y = 8 is a solution of the equation.

Answer:

x=31, x=31, x=21.

Step-by-step explanation:

So for number 33, we see that 2x+28=90 degrees so you just simplify the equation to 2x=62, x=31.

For number 34, we see that 4x+56=180 (flat line), so we simplify the equation again and get 4x=124, x=31 degrees.

For number 35, according to the vertical angle theorem, 43=2x+1, so we simplify that too and we get 42=2x, 21=x, x=21.

Answer:

m∠1 = 148°  and m∠2 = 32°

Step-by-step explanation:

m∠1 + m∠2 = 180°  (supplementary angles)

4x° + (x - 5)° = 180  (substitution)

4x + x - 5 = 180

5x - 5 = 180

5x = 185

x = 37

m∠1 = 4(37)° =148°  and m∠2 = (37 - 5)° = 32°

Answer:

slope (m)= 2/7

X1= 1

y1= 2

formula from equation of the line:

1. Y2 - Y1/ X2 - X1 ( if you know 2 point )

2. y - y1 = m × ( x - x1 ) (if you know the slope and 1 point )

3. mx + c = y ( if you know the slope and the y-axis )

because the known gradient and 1 point, then use the formula number 2.

let's get into the formula:

y - y1= m × (x -x1)

y - 2 = 2/7 × ( x - 1 )

y - 2 = 2/7x - 2/7

y= 2/7x - 2/7 + 2

y = 2/7x + 12/7

[tex]C.\ (4, 16)[/tex]

[tex]D.\ (\frac{1}{2}, \frac{1}{4})[/tex]

Answer:

[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]

Step-by-step explanation:

Given

[tex]y = x^2[/tex]

Required

Determine which of the given points is not true

[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]

Here

[tex]x = \frac{3}{2}[/tex] and [tex]y = \frac{9}{2}[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]\frac{9}{2} = (\frac{3}{2})^2[/tex]

[tex]\frac{9}{2} = \frac{3}{2}*\frac{3}{2}[/tex]

[tex]\frac{9}{2} \ne \frac{9}{4}[/tex]

Both sides of the equation are not equal. Hence, this point do not line on the curve

[tex]B.\ (-1, 1)[/tex]

Here

[tex]x = -1[/tex]  and [tex]y = 1[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]1 = (-1)^2[/tex]

[tex]1=1[/tex]

Both sides of the equation are equal. Hence, this point line on the curve

[tex]C.\ (4, 16)[/tex]

Here

[tex]x = 4[/tex]  and [tex]y = 16[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]16 = 4^2[/tex]

[tex]16 = 16[/tex]

Both sides of the equation are equal. Hence, this point line on the curve

[tex]D.\ (\frac{1}{2}, \frac{1}{4})[/tex]

Here

[tex]x = \frac{1}{2}[/tex]  and [tex]y = \frac{1}{4}[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]\frac{1}{4} = (\frac{1}{2})^2[/tex]

[tex]\frac{1}{4} = \frac{1}{2}*\frac{1}{2}[/tex]

[tex]\frac{1}{4} = \frac{1}{4}[/tex]

Both sides of the equation are equal. Hence, this point line on the curve

From the calculations above; only [tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex] do no lie on the curve

Answer:

The 45th term is equal to -209.

Step-by-step explanation:

I got stuck on this question for six attempts. Therefore I started trying other methods. I started with a10=1 and then subtracted 6 to get a11=-5. I continued this process until I reached a45=-209

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference. The 45th term for the arithmetic sequence is -209.

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

The explicit formula for any arithmetic series is given by the formula,

aₙ = a₁ + (n-1)d

where d is the difference and a₁ is the first term of the sequence.

Given that the 10th term of the arithmetic series is 1, while the common difference of the arithmetic series is -6. Therefore, 10th term of the series can also be written as,

aₙ = a₁+(n-1)d

1 = a₁+(10-1)(-6)

1 = a₁ + (9)(-6)

1 = a₁ - 54

a₁ = 55

Now, the 45th term for the arithmetic sequence is,

aₙ = a₁ + (n-1)d

a₄₅ = 55 + (45-1)(-6)

a₄₅ = 55 - 264

a₄₅ = -209

Hence, the 45th term for the arithmetic sequence is -209.

Answer:

Exponential growth

4%

12

Step-by-step explanation:

Given the function :

​f(n) = 12(1.04)^n​

Part A: Is this a growth or decay exponential function?

The equation above is usually generally represented as :

F(n) = A(1 ± r)^n

Where F(n) = final amount after n years ; r = rate ; n = number of years

The function Given above is thus :

F(n) = 12(1 +0.04)^n

This is an exponential growth function because of the negative rate (+ 0.04)

Part B: What is the growth or decay percentage for this function

From the equation :

F(n) = A(1 + r)^n ; r = rate

Comparing F(n) = 12(1 +0.04)^n ; r = 0.04 = 0.04*100% = 4%

Part C: What does the y-intercept of the graph of the function f(n) represent?

The y intercept :

Value of F(n) when n = 0

F(n) = 12(1 +0.04)^n

F(n) = 12(1 +0.04)^0

Fn = 12(1)

Hence, intercept = 12

Answer:

Will Fredericks recipe make 10 loaves?

Step-by-step explanation:

It is given that Fredick and Kate have flour  [tex]$=17\frac{1}{3}$[/tex]   cups

And Fredrik has a recipe where he calls for [tex]$1\frac{5}{8}$[/tex]  cups of flour while Kate calls for [tex]$1\frac{3}{4}$[/tex] cups of floor.

So first we add the total cups of floor that they have

i.e. [tex]$17+\frac{1}{3} = \frac{52}{3}$[/tex]

Similarly cups of flour in the recipe of Fredrick = [tex]$1+\frac{5}{8}= \frac{13}{8}$[/tex]

Therefore, number of loaves that Fedrick can make is

[tex]$=\frac{\frac{52}{3}}{\frac{13}{8}}$[/tex]

[tex]$=\frac{52}{3 }\times \frac{8}{13}$[/tex]

[tex]$=\frac{32}{3}$[/tex]

= 10 .667

Therefore, with Fedrick's recipe, he can make 10 numbers of loaves.
