Answer:

  ∠CBE = 59°

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary.

  ∠BCD +∠CDE = 180°

  ∠BCD +∠CDB +∠BDE = 180°

  (21x -5) +34 +(4x+1) = 180

  25x +30 = 180

  25x = 150

  x = 6

∠CBE = ∠CDE = 34 +(4x +1) = 4x +35 = 4(6) +35

∠CBE = 59°

Answer:

Step-by-step explanation:

6 years from now, Johnson will be 12 years older than Agnes and twice her age. That means Agnes will be 12 and Johnson will be 24.

Agnes is 6 now, and Johnson is 18 now.

Answer:

B should be the correct answer.

Step-by-step explanation:

15 + 11 + 9 + 12 + 6 + 11 = 64

64<90

Answer:

15 red out of 64 total markers

15 / 64 = .234375

90 x .234375 = 21.09375

so she will pick a red marker about 21 times

Answer:

y = 2x

Step-by-step explanation:

Total distance walked = y

Number of trips = x

Lily walks 2 kilometers during each trip to school

Equation that shows the

relationship between the number of trips x and the total distance walked y:

y = 2x

For example, if the number of trips (x) is 3

Total distance walked,y = 2(3)

y = 6 kilometers

Answer:

4xy

Step-by-step explanation:

(x+y) (x+y) - (x-y) (x-y)​

(x² + xy + xy + y²) - (x² - xy - xy + y²)

(x² + 2xy + y²) - (x² - 2xy + y²)

x² + 2xy + y² - x² + 2xy - y²

x² - x² + 2xy + 2xy + y² - y²

4xy

Answer:

that could literally be anything, as long as the first sum is greater then the second.

example;

(2+4) (3+5) - (6+1) (5+2)

(or, 6+8 = 14, 7+7 = 14, 14 - 14 = 0)

Hi there!

[tex]\large\boxed{\text{Average rate = 1}}[/tex]

We can calculate the average rate of change using the following:

[tex]ARC = \frac{f(b)-f(a)}{b-a}[/tex]

Thus, we can plug in the endpoints of -4 and -2. Find the corresponding y-values for these x-values:

f(-2) = -(-2)² - 5(-2) + 8  = -4 + 10 + 8 = 14

f(-4) = -(-4)² - 5(-4) + 8 = -16 + 20 + 8 = 12

Plug in the solved for values into the ARC equation:

[tex]ARC(slope) = \frac{14-12}{-2(-4)} = \frac{2}{2} = 1[/tex]

Step-by-step explanation:

Follow the PEMDAS order of operations:

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction.

Calculate the Parentheses- (12-8)

This will equal 4.

Answer: 2 units long

Answer:

13:5

Step-by-step explanation:

Messy played 65 minutes while the substitute played 25 minutes. This ratio is 65:25 and can be simplified to 13:5.

Answer:

3 + 7 + 2= 12

Step-by-step explanation:

It is made true because the equation adds up to the number. If we take 3+7 it equals to 10. Then we take 10 and add it to 2, which gives us 12.

Hope this helps :)

The value of the missing number x will be 10.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Let the missing number be x. Then the equation can be written as,

3 + 7 + 2 = x + 2

Simplify the equation, then the value of the variable x will be

3 + 7 + 2 = x + 2

3 + 7 + 2 - 2 = x

x = 3 + 7

x = 10

The value of the missing number x will be 10.

Answer:

y = 6

Step-by-step explanation:

y varies directly with x

y = k*x

Where,

k = constant of variation

Find y when x = 2 and constant of variation,k =3

y = k*x

y = 3 * 2

y = 6

Check:

if y = 6 and x = 2, find k

y = k*x

6 = k*2

6 = 2k

k = 6/2

k = 3

Answer:

Step-by-step explanation:

a = 1

b = 6

c = 6

axis of symmetry =  -(6) / 2*1

= -6 /2

= -3

vertex = ( -3,  -3 )   :)

Answer:

Step-by-step explanation:

a = 1 because if is not written what x^2 multiply, it means that x^2 multiply 1

b = 6  b is the term that multiply x

c = 6  c is the therm without x

axis of symetry = -6/2 = -3

the x of vertex is same of the axis of the symmetry so it is -3

if we subistute x with this value we can find the y of vertex

(-3)^2 + 6(-3) + 6 = 9 -18 + 6 = -3

Vertex (-3, -3)

Answer:

Is there a picture?

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

48 square. Units

Step-by-step explanation:

Given that :

Triangle and rectangle have the same base, b and height, h

AREA of triangle = 0.5 * base * height

48 = 0.5 bh

bh = 0.5 * 48

bh = 96

Total area of section 1 & 2 :

bh = area of triangle + x

X = bh - area of triangle

X = 96 - 48

Area of se tion 1&2 = 48

m is called an outlier and it is a positive association

Answer:

Part A) Part N.) is called the cluster of the whole chart. Part M.) is called the outlier because it's not with the rest of the group, therefore, it's the outlier of the group.

Part B.)

The association between the students' test scores and the number of hours they've studied is a positive correlation. That means the longer the students spent time studying for their tests... the better grades they got because of it. It's a lot like a cause-and-effect kind of situation.

Given:

The function is:

[tex]f(x)=2.9646(1.0170)^x[/tex]

To find:

Rewrite the exponential equation given above using base e.

Solution:

The exponential models is:

[tex]f(x)=P(1+r)^x[/tex]         ...(i)

Where P is initial values, r is the rate of interest and x is the time period.

The exponential models using base e is:

[tex]f(t)=Pe^{rt}[/tex]           ...(ii)

Where, P is initial values, r is the rate of interest and t is the time period.

The given function is:

[tex]f(x)=2.9646(1.0170)^x[/tex]

It can be written as:

[tex]f(x)=2.9646(1+0.0170)^x[/tex]        ...(iii)

On comparing (i) and (iii), we get

[tex]P=2.9646[/tex]

[tex]r=0.0170[/tex]

Putting [tex]P=2.9646[/tex] and [tex]r=0.0170[/tex] in (ii), we get

[tex]f(t)=2.9646e^{0.0170t}[/tex]

Therefore, the correct option is D.

Answer:

444 :) (angel number, haha)

Step-by-step explanation:

it needs 74 times 2 mm which is 148 I think, which will also be the length since 148 is 2 times more than 74

so it's : 74 + 74 + 148 + 148 which is basically just 148 times three, so the answer is 444!
