Find the value of x?


23.5°


43°


47°


86°

Answer:

A

Step-by-step explanation:

We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.

Here, the length is l = x and the width is w = x + 3. So, plug these in:

A = lw

A = x(x + 3)

Expand this out:

A = x² + 3x

The answer is thus A.

Answer:

A

Step-by-step explanation:

Area = length × width

Area = x × (x + 3)

A(x) = x²+ 3x

Answer:

C. 93 students

Step-by-step explanation:

25 x 124 = 3100

3100/100 = 31

124 - 31 = 93

Therefore, 93 students do NOT purchase their lunches in the cafeteria.

Answer: C. 93 students do not purchase their lunches in the cafeteria.

Step-by-step explanation:

25% * 124= 31  

124 - 31 = 93

Answer:

Ax + By = C

A, B and C can be any number--including negative numbers, zero and one! So examples of standard form can look like this:

3_x_ + 7_y_ = 10, where A = 3, B = 7 and C = 10.

Or they can look like this:

x + 5_y_ = 6. In this case, A = 1, B = 5 and C = 6.

Or this:

8_y_ = 9. In this case, A = 0, which is why x does not appear in the equation. B = 8 and C = 9, as you would expect.

And here's one more:

3_x_ − 5_y_ = 12. Here, A = 3, B = −5 and C = 12. Notice that in this case, B is negative five!

The standard form of a linear equation is Ax + By = C, where A, B and C can be any number.

What is the solution to 4^(log4(x+8))=4^2 x=-8 x=-4 x=4 x=8. 2.

Step-by-step explanation:

=-8 x=-4 x=4 x=8. 2.

Answer:

8

Step-by-step explanation:

4^log4(x+8) = 4^2

log₄(x+8)=2

(log(x+8))/log4=2

log(x+8)=2log4

log(x+8)=log16

x+8=16

x=8

The procedure to solve the equation x / 19.3 = 38.6 is to multiply both sides of the equation by 19.3. The solution is 744.98.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

The equation is given in the question following as:

x / 19.3 = 38.6

To solve the equation, you would multiply both sides by 19.3 to get :

⇒ x = 19.3 × 38.6

Apply the multiplication operation, and we get

⇒ x = 744.98.

So, the solution is x = 744.98.

Therefore, the correct answer is D. Multiply both sides by 19.3; the solution is 744.98.

Answer:

1/27

Step-by-step explanation:

There are 9 numbers between 0 and 8.  3 of them are less than 3 (0, 1, and 2), and 1 of them is 6.

The probability is therefore (3/9) (1/9) = 1/27.

Answer:

y=3x+1

Step-by-step explanation:

It would be y=3x+1 because if you replace x with 2 and do y=3(2)+1 you would get y=6+1 or just y=7 and in the table for 2 years it says 7 paintings.

Answer:

To set up this equation, we want to find the total change in time (x) over 4 years if every year your time decreases by 6 seconds. Our equation should look something like this:

x = 6*4

To solve this, you just have to multiply 6*4!

x = 24

This means that over 4 years, you have cut 24 seconds off of the time it takes you to run a mile! Your total change in time would then be 24 seconds!

area of triangle = (b x h) / 2

area of triangle = (14 x 24) / 2

A.I.T = 168 cm^2

As there are 2 triangles, double this value

Area of triangles = 168 x 2 = 336 cm^2

Area of rectangle = 25 x 10 = 250

As there are 2 of the same rectangle, double this value

250 x 2 = 500

Area of rectangle = 10 x 14 = 140 cm^2

Add all the values together to get the total surface area

140 + 500 + 336 = 976

The answer is 976 cm^2

a) The correct statement to find the depth of the lake is,

⇒ 156 + |- 458|

b) The depth of the lake is,

⇒ 614 m

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The surface of Great Slave Lake is 156 m above sea level.

And, At the deepest point, the bottom of the lake is 458 m below sea level.

Here, The depth of the lake is find as;

Step-by-step explanation:

1*2=2

2*2=4

4*2=8

8*2=16

16*2=32

The sequence 1, 2, 4, 8, 16, 32 is geometric sequences, Option D is correct.

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the preceding term by a fixed constant called the common ratio.

Let us check all the options for geometric sequence

2, -2, 2, -2, 2-2, 2

This is not a geometric sequence because the terms are not multiplied by a common ratio to get the next term.

1.4. 9, 16, 25, 36, 49

This is not a geometric sequence because there is no common ratio between the terms.

10.5, 2.5, 1.25, 0:625, 0.3125

This is not a geometric sequence because there is no common ratio between the terms.

1, 2, 4, 8, 16, 32

This is a geometric sequence because each term is obtained by multiplying the previous term by the common ratio of 2.

Therefore, the sequence 1, 2, 4, 8, 16, 32 is geometric sequences, Option D is correct.

Answer:

incorrect

Step-by-step explanation:

The calculation he has done only calculates the distance between the y- coordinates of the points.

Calculate the distance d using the distance formula.

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (2, - 5)

d = [tex]\sqrt{(2+2)^2+(-5+3)^2}[/tex]

   = [tex]\sqrt{4^2+(-2)^2}[/tex]

   = [tex]\sqrt{16+4}[/tex]

   = [tex]\sqrt{20}[/tex] = [tex]\sqrt{4(5)}[/tex] = 2[tex]\sqrt{5}[/tex] ← exact distance

Answer:Sample Response: No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.

Answer:

They would take 27 days

Step-by-step explanation:

If 24 electricians can to the work to wire a new housing subdivision in 36 days.Therefore,32 electricians will take lesser days to complete it.

So,let the no. of days needed to complete the work by 32 electricians be x;

As the no.of days are decreasing with the increasing no. of electricians;it can be called as inverse variation

Therefore,

24 × 36 = 32 × x

x = 24 × 36 ÷ 32 (by cross multiplication method)

x = 27

Thus,It will take 27 days for 32 electricians to complete the same work which 24 electricians needed to complete in 36 days

The change rate is just to big to differ from 2-4 and M isnt the same rate as P in the problem, so the answer would be C. (hoped this helped :D

Answer:

A

Step-by-step explanation:

Rate of change of the functions is measured by their slopes.

Function M

Calculate slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (0, 1) ← 2 ordered pairs from the table

m = [tex]\frac{1+9}{0+2}[/tex] = [tex]\frac{10}{2}[/tex] = 5

Function P

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 7x + 9 ← is in slope- intercept form

with m = 7

Thus

Their rates of change differ by 2 → A

Answer:

∠LOA≅∠LMA

Step-by-step explanation:

The first two options are incorrect because you need one more set of congruent ANGLES, not SIDES. The last option would prove congruency, but through ASA, not AAS. So it would be the third option.

For both triangles to be congruent by the AAS congruence theorem, the additional information needed is: C. ∠LOA ≅ ∠LMA.

The AAS congruence theorem states that two triangles are proven to be congruent when they have two pairs of corresponding congruent angles and a pair of non-included sides that are congruent.

From the diagram given, we already known that:

LA ≅ LA [congruent side]

∠OLA ≅ ∠MLA [one pair of congruent angles]

Therefore, an additional information that would make both triangles congruent by the AAS congruence theorem is: C. ∠LOA ≅ ∠LMA.
