Answer:

D. x = 10

Step-by-step explanation:

Perimeter = the sum of all sides lengths

Perimeter = 30 (in this case)

so...

[tex]((x-5)+x)2=30[/tex]

Step 1. Dividing 3 to both sides

[tex]((x-5)+x)=15[/tex]

Step 2. Add 5 to both sides

[tex]x+x=20[/tex]

Step 3. Solve for x

Since x + x = 20, to solve for one of the x means solving for the other x

so since 2 x's are being added with the same value, divide 20 by 2.

x = 10

Step-by-step explanation:

Astronomers were trying to find the weight of six planets - Mars, Venus, Pluto, Jupiter, Mercury and Saturn. The number of planets lighter than Mars was equal to the number of planets heavier than Venus. Saturn was heavier than Mars and Mercury was heavier than Pluto. Venus was lighter than Mars. Saturn was not the heaviest planet.

725.40

Step-by-step explanation:

Since, every day she works from 6:15am to 4:15pm

this will put her working to 10 hrs a day and subtracting 1 hr break, the total working period would be 9 hrs a day.

And, total working hours per week would be (9*5) hrs = 45 hrs

thus, her total salary per week would be $(45*16.12) = $725.40

Answer:

8.79 % tax rate

Step-by-step explanation:

total paid = tax + price

57.50 = tax +52.85

tax = 4.65

tax rate =( tax ÷ price before the tax) × 100%

= (4.65÷ 52.85) × 100%

= 8.79%

Answer:

Option C

Step-by-step explanation:

Sum of two angle in complement = 90

Let the other angle be a

a + 5x + 13 = 90

a = 90 - (5x + 13)

a = 90 - 5x - 13

a = 77 - 5x

The measure of the compliment of ∠K is ∠ J = (77 − 5x)°.

We have a angle - ∠K = (5x+13)°.

We have to find the Complement of ∠K.

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

∠X + ∠Y = 90

According to the question, we have -

The measure of angle ∠ K = (5x+13)°.

Assume that the complement of ∠K is ∠ J.

Then -

∠ K + ∠ J = 90

∠ J  = 90 - ∠ K

∠ J = 90 - (5x + 13)

∠ J  = 90 - 5x - 13

∠ J  = 77 - 5x

∠ J = (77 − 5x)°

Hence, the measure of the compliment of ∠K is ∠ J = (77 − 5x)°

Step-by-step explanation:

which angle ? all of them ?

in such a case of intersection the various angles are mirrored or have to fulfill the complementary 180 degree criteria.

when we look either on the top or the bottom of the intersected line, there is always a half circle that can be drawn with its center in the intersection point.

therefore, the sum of such 2 neighboring angles (like 1 and 43 degrees) must be 180 degrees. the same for 2 and 3.

at the same time 2 is a mirrored version of 43 degrees, and 3 is a mirrored version of 1.

so,

1 + 43 = 180

1 = 137 degrees

2 = 43 degrees

3 = 137 degrees

a=2.86

Answer:

Part B: The dimensions are (4x + 3y) and (4x - 3y)

Step-by-step explanation:

our equation is: (16x^2 - 9y^2)

With this equation, we must plug it into the formula: (a + b)(a - b) = a^2 - b^2

so,

a^2 = 16x^2

b^2 = 9y^2

then,

a = sqrt(16x^2) = 4x

b = sqrt(9y^2) = 3y

(these are the correct variables because 3*3 = 9, and 4*4 = 16)

now, we plug this information back into the formula again;

(a + b)(a - b) = (4x + 3y)(4x - 3y)

therefore, (4x + 3y)(4x - 3y) is the answer!

I hope this helps, have a wonderful day!

Answer:

[tex]\boxed {\boxed {\sf m= \frac{1}{2}}}[/tex]

Step-by-step explanation:

We are asked to find the slope of a line that passes through 2 points. The slope tells us the steepness and direction of a line. It is calculated using the following formula:

[tex]m= \frac {y_2-y_1}{x_2-x_1}[/tex]

In this formula, (x₁ , y₁) and (x₂, y₂) are the points the line passes through. The points are (4,4) and (10,7). If we match the value and the corresponding variable we see that:

Substitute the values into the formula.

[tex]m= \frac{7-4}{10-4}[/tex]

Solve the numerator.

[tex]m= \frac{3}{10-4}[/tex]

Solve the denominator.

[tex]m= \frac{3}{6}[/tex]

This fraction can be reduced. Both the numerator and denominator can be divided by 3.

[tex]m= \frac{3/3}{6/3}[/tex]

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

The slope of the line that passes through (4,4) and (10,7) is 1/2.

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.

Variable: A variable is a symbol that doesn't have a fixed value.

Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.

Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given:

A^B(B +2)

As, both are in ratio of multiplication and B is also the power for A.

There is no possible of decreasing the quantity.

Hence, if A is constant then B increasing and B is constant then A is increasing .
