Charlene's age is 4 less than 3 times Mary's age, x.
Which expression represents Charlene's age?

O A 3X - 4

OB. 3(x-4)

O C. 4X-3

OD. 4 - 3x

Answers

The answer would be A

The solution is Option A

The equation of Charlene's age is 3x - 4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let Charlene's age be C

The age of Mary is = x

Now , the equation is

Charlene's age is 4 less than 3 times Mary's age

Substituting the values in the equation , we get

C = 3 x ( Mary's age ) - 4

On simplifying the equation , we get

C = 3x - 4    be equation (1)

Therefore , the value of C is 3x - 4

Hence , the age of Charlene's age is 3x - 4

Answers

Answer:

B: 8

Step-by-step explanation:

The area of the two smaller squares equals the area of the big square so find the area to the big square

289 - 225 = 64

The square root of 64 is 8 so the answer is 8.

Translate (-3, 1) to the right 1 unit.
Then reflect the result over the y-axis.
What are the coordinates of the final point?
OD
?

Answers

Answer:

(2,1)

Step-by-step explanation:

When we translate to the right, we are simply adding a value to the x axis value corresponding to the units of translation

We have the translation by 1 unit, so we are to add 1 to the value of the x-coordinate

Thus, we have this as ;

(-3 + 1, 1)

= (-2,1)

When we reflect a point (x,y) over the y-axis, its new coordinates become (-x,y)

Applying this to what we have above, the coordinate of the final point will be (2,1)

The descriptions below outline different payment options for Ashley's dog-walking business. Use x to represent the number of days she walks a dog and y to represent her earnings. For each equation and graph, drag the situation that can be modeled by that relationship into the space in that row.

Answers

Answer:

Step-by-step explanation:

y = 2x - 2 (Linear)

Here, x = number of days

y = Total payment

Ashley paid $2 each day and gives $2 to her brother.

y = 2x²

This quadratic relation represents the total payment 'y' is twice as much as the number of days times itself.

y = 2ˣ

Exponential function represents that the total payment is twice as much as the number of days times itself.

A function is a mathematical rule which can be assigned a value.

What is a function?

A function in mathematics is a rule that can be assigned a value. We shall now procced to find out which function can be classified as shown.

Ashley paid $2 each day and gives $2 to her brother - This is a quadratic function and has the equation; y = 2x²

The total payment is twice as much as the number of days time itself - This is a linear function with the equation - y= 2x - 2 y = 2x²

The total payments starts at $2 each day and doubles for each day - this is a exponential  function with the equation y = 2ˣ

Answers

Answer:

[tex]\mathrm{d. \csc \theta =\frac{5}{3}}[/tex]

Step-by-step explanation:

In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\cot\theta =\frac{4}{3}[/tex] as given in the problem, then [tex]\tan \theta =\frac{3}{4}[/tex], because [tex]\tan \theta =\frac{1}{\cot \theta}[/tex]. Therefore, the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].

The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse.

Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h) and since [tex]\sin \theta =\frac{1}{\csc \theta}[/tex], we have:

[tex]\csc \theta=\frac{1}{\sin \theta}=\frac{1}{\frac{3}{5}}=\boxed{\frac{5}{3}}[/tex]

A foot ball field measures 100m by 72m. A school marks a football field similar in shape to a fullsize football field but only 30m long. What is its width?

Answers

Answer: 21.6 m

Step-by-step explanation:

Given

A football field measures [tex]100\ m\times 72\ m[/tex]

If a football field similar in shape to a full size  has a length [tex]l=30\ m[/tex]

The ratio of the length of the original to the small field is the same

Assume the width of the small field is  w

[tex]\therefore \dfrac{100}{30}=\dfrac{72}{w}\\\\\Rightarrow w=30\times \dfrac{72}{100}\\\\\Rightarrow w=21.6\ m[/tex]
