The number multiplied by the variable is called the ______________ of the variable.

Answer:

the one that doesn't belong is 5/3

Answer:

Step-by-step explanation:

x = 52°

b = ¹/₂(2x) = x = 52°

y = 180° - 90° - x

y = 90° - 52° = 38°

a = 180° - 90° - y = 90° - 38° = 52°

p = 83°

q = ¹/₂p = 41.5°

(180° - c) + b + q = 180°

180° - c + 52° + 41.5° = 180°

    - c = - 93.5°

       c = 93.5°

Answer:

x = 15/2

Step-by-step explanation:

Solve for x:

x - 5 = 2 + 1/2

Hint: | Put the fractions in 2 + 1/2 over a common denominator.

Put 2 + 1/2 over the common denominator 2. 2 + 1/2 = (2×2)/2 + 1/2:

x - 5 = (2×2)/2 + 1/2

Hint: | Multiply 2 and 2 together.

2×2 = 4:

x - 5 = 4/2 + 1/2

Hint: | Add the fractions over a common denominator to a single fraction.

4/2 + 1/2 = (4 + 1)/2:

x - 5 = (4 + 1)/2

Hint: | Evaluate 4 + 1.

4 + 1 = 5:

x - 5 = 5/2

Hint: | Isolate terms with x to the left hand side.

Add 5 to both sides:

x + (5 - 5) = 5/2 + 5

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

x = 5/2 + 5

Hint: | Put the fractions in 5/2 + 5 over a common denominator.

Put 5/2 + 5 over the common denominator 2. 5/2 + 5 = 5/2 + (2×5)/2:

x = 5/2 + (2×5)/2

Hint: | Multiply 2 and 5 together.

2×5 = 10:

x = 5/2 + 10/2

Hint: | Add the fractions over a common denominator to a single fraction.

5/2 + 10/2 = (5 + 10)/2:

x = (5 + 10)/2

Hint: | Evaluate 5 + 10.

5 + 10 = 15:

Answer: x = 15/2

Answer:

7 1/2

Step-by-step explanation:

Hello!

To solve this we have to get x by itself

What we do to one side of the equation we have to do to the other

-5 + x = 2 1/2

To get -5 to the other side we have to add 5 to make it zero

What we do to the left side we have to do to the right

-5 + 5 + x = 2 1/2 + 5

Simplify

0 + x = 7 1/2

We can drop the 0

x = 7 1/2

The answer is 7 1/2

Answer:

From the pythagorean theorem:

AB²+BC²=AC²

x+35²=37²

x+1225=1369

x=1369-1225

x²=144 cm

x=radical 144=12

Answer:

[tex]\huge\boxed{b = 12 cm}[/tex]

Step-by-step explanation:

Using Pythagorean Theorem:

[tex]c^2 = a^2 + b^2[/tex]

Where c is hypotenuse(37 cm), and one of the side is 35 cm.

=> [tex]37^2 = 35^2 + b^2[/tex]

=> [tex]b^2 = 37^2-35^2\\[/tex]

=> [tex]b^2 = 1369 - 1225\\[/tex]

=> [tex]b^2 = 144[/tex]

Taking sqrt on both sides

=> b = 12 cm

Answer:

B

Step-by-step explanation:

Just took the quiz!

The solution is : B = Barbara’s equation did not consider the number of bottles of iced tea.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

given that,

Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle.

Let the water bottles she needs to sell be = x

Let the iced tea she needs to sell be = y

As she wants $100, she has to sell the following numbers of drinks.

1.25x + 1.49y = 100

But, Barbara wrote an equation

1.25x + 1.49 = 100

She did not put a variable with 1.49, that will depict the number of iced teas she needs to sell.

Hence, option B is correct.

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 292 yards

The statement

The length of the field is 7 yards less than double the width is written as

l = 2w - 7

Substitute the expression into the above formula and solve for the width

292 = 2( 2w - 7) + 2w

292 = 4w - 14 + 2w

292 = 6w - 14

6w = 292 + 14

6w = 306

Divide both sides by 6

w = 51

Substitute this value into l = 2w - 7

That's

l = 2(51) - 7

l = 102 - 7

l = 95

Therefore we have

length = 95 yards

width = 51 yards

D. 4[tex]m^{2}[/tex]

Step-by-step explanation:

First find the area of 1 tile

= 8 * 5

= 40[tex]cm^{2}[/tex]= 40/10000 = 0.004

no. of tiles= 1000

=4[tex]m^{2}[/tex]

Answer:

The answer is below

Step-by-step explanation:

The compound interest is given by the formula:

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

Where A is the final amount, p is the principal (initial amount), r is the rate, t is the number of period and n is the number of times it was compounded per period.

Given that:

The interest is compounded yearly, i.e n = 1, for 1 year, t = 1, the compound interest is Rs 450 i.e A = 450. Therefore:

[tex]450=P(1+\frac{r}{1} )^{1*1}=P(1+r)\\450=P(1+r).\ .\ .\ (1)[/tex]

For 2 year, t = 2, the compound interest is Rs 945 i.e A = 945. Therefore:

[tex]945=P(1+\frac{r}{1} )^{1*2}=P(1+r)^2\\945=P(1+r)^2.\ .\ .\ (2)[/tex]

Dividing equation 2 by equation 1 gives:

2.1 = 1 + r

r = 2.1 - 1 = 1.1

r = 1.1

Put r = 1.1 in 450 = P(1 + r)

450 = P(1 + 1.1)

450 = 1.11P

P = 405.4

Therefore the rate is 1.1 = 110% and P = Rs 405.4

Answer:

The area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet is 482.8 ft².

Step-by-step explanation:

An octagon is a polygon with eight sides. An octagon is regular (also called a regular octagon) is a polygon with all eight sides equal.

The apothem of a regular octagon is the shortest distance between the center and any of its sides, in other words, it is the distance that separates the center of the polygon from the central point of each side of the octagon.

The area is calculated using the following formula:

[tex]Area=\frac{n*L*Ap}{2}[/tex]

Where:

Being n = 8 being an octagon and the perimeter P the sum of the sides of the octagon (P = 8 * L), the area of ​​the regular octagon can be calculated by:

[tex]Area=\frac{P*Ap}{2}[/tex]

In this case:

Replacing:

[tex]Area=\frac{80ft*12.07ft}{2}[/tex]

Solving:

Area=482.8 ft²

The area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet is 482.8 ft².

  f(-3) = -20

Step-by-step explanation:

We observe that the given x-values are 3 units apart, and that the x-value we're concerned with is also 3 units from the first of those given. So, a simple way to work this is to consider the sequence for x = 6, 3, 0, -3. The corresponding sequence of f(x) values is ...

  34, 10, -8, ?

The first differences of these numbers are ...

  10 -34 = -24

  -8 -10 = -18

And the second difference is ...

  -18 -(-24) = 6

For a quadratic function, second differences are constant. This means the next first-difference will be ...

  ? -(-8) = -18 +6

  ? = -12 -8 = -20

The value of the function at x=-3 is -20.

Answer in percent form = 5.333% (approximate)

=======================================================

Work Shown:

A = event of pulling a yellow marble on the first selection

P(A) = 2/15 since there are 2 yellow out of 6+7+2=15 total.

B = event of pulling a blue marble on the second selection

P(B) = 6/15 = 2/5

Note how the 15 does not drop to 14 since we put the first marble back. Therefore events A and B are independent

---------

P(A and B) = probability of getting yellow, then blue

P(A and B) = P(A)*P(B)

P(A and B) = (2/15)*(2/5)

P(A and B) = (2*2)/(15*5)

P(A and B) = 4/75

P(A and B) = 0.05333 approximately

P(A and B) = 5.333% approximately

Answer:

(x+8)²

Step-by-step explanation:

x² + 16x + 64 = (x+8)²

(x+8)² = (x+8)(x+8) = x*x + x*8 + 8*x + 8*8 = x² + 8x + 8x + 64

         = x² + 16x + 64

Use a rigid transformation to prove that angle NPO is congruent to angle NLM

=====================================================

Explanation:

The AA stands for "angle angle". So we need two pairs of angles to prove the triangles to be similar. The first pair of angles is the vertical angles ONP and MNL, which are congruent. Any pair of vertical angles are always congruent.

The second pair of angles could either be

so we have a choice on which to pick. The pairing angle NOP = angle NML is not listed in the answer choices, but angle NPO = angle NLM is listed as choice B.

Saying angle NLM = angle LMN is not useful because those two angles are part of the same triangle. The two angles must be in separate triangles to be able to tie the triangles together.

We would use a rigid transformation to have angle NPO move to angle NLM, or vice versa through the use of a rotation and a translation.

Angle Angle AA similarity postulate states that two triangles are similar if

two angles in one of the triangles are congruent (equal) to two angles in the

other triangle

The correct option for the method and additional information that would

prove triangle ONP and triangle MNL similar by AA similarity postulate is

option B.

B. Use rigid transformation to prove that angle NPO is congruent to angle NLM

The reason for arriving at the above selection is as follows;

The known parameter in triangle ΔONP and ΔMNL are;

Lines MO and LP intersect at vertex point N.

The angles on opposite side of the point N (either side of the X shape

formed by the two lines) which are ∠ONP and ∠LNM are vertically opposite

angles or opposite angles.

According to vertically opposite angles theorem ∠ONP and ∠LNM, which

are vertically opposite angles are congruent, and we can write.

∠ONP ≅ ∠LNM

The required parameter;

To find the additional information that would prove ΔONP and ΔMNL by

AA (Angle-Angle) similarity postulate.

Strategy;

Given that from the drawing, one (vertex) angle in one triangle is congruent

to one (vertex) angle in the other triangle, that is ∠ONP ≅ ∠LNM, it is

required to prove that one other angle in triangle ΔONP is congruent to a

corresponding angle in triangle ΔMNL.

Solution;

Prove that either ∠NPO or ∠NOP in ΔONP are congruent to ∠NLM or

∠NML respectively in ΔMNL by performing rigid transformations

(transformations that does not change shape) on either ΔONP or ΔMNL

including;

Therefore, the correct option is option B. Use rigid transformation to prove

that angle NPO is congruent to angle NLM.
