The correct expression that represents her father's age is A.[tex]\(3x - 4\).[/tex]

To arrive at this conclusion, let's analyze the given information:

Marcy determined that her father's age is four less than three times her age. Let's denote Marcy's age as x. According to the statement, her father's age can be expressed as three times Marcy's age minus four years.

Mathematically, this can be written as:

[tex]\[ \text{Father's age} = 3 \times \text{Marcy's age} - 4 \][/tex]

Substituting x for Marcy's age, we get:

[tex]\[ \text{Father's age} = 3x - 4 \][/tex]

Now, let's evaluate the other options to confirm that they are incorrect:

B. x - 4: This expression suggests that the father's age is four years less than Marcy's age, which does not match the given information that the father's age is four less than three times Marcy's age.

C. 4x - 3: This expression indicates that the father's age is three years less than four times Marcy's age, which again does not align with the given information.

D. 4 - 3x: This expression would imply that the father's age is calculated by subtracting three times Marcy's age from four, which is not the relationship described in the problem.

Therefore, the only expression that correctly represents the father's age based on the given information is A. [tex]\(3x - 4\).[/tex]

Answer:

Yes

Step-by-step explanation:

It can be 6 units. The rule relating to the sides of the triangle is that you should be able to add two sides and get a length that is longer than the third side. You usually add the lower two numbers because it basically says that it will work for all sides but, if you're still in doubt you just have to compare the numbers.

For Example

3+5 is greater than 6

5+6 is greater than 3

6+3 is greater than 5.

All of these makes sense so 6 can be a possible answer.

In triangle EFG, it is not possible for segment GE to measure 6 units.

No, it is not possible for segment GE to measure 6 units in triangle EFG.

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Since segment EF measures 3 units and segment FG measures 5 units, the sum of these two sides is 8 units, which is less than 6 units. Therefore, segment GE cannot be 6 units long in triangle EFG.

Answer:

17 dimes, 21 quarters

Step-by-step explanation:

I suppose you want to know how many dimes and quarters she had in her jar.

Let's say x = dimes and y = quarters.

We can make the following 2 equations:

1) x + y = 38 (number of coins in the jar)

2) 10x + 25y = 695 (a number of dimes plus a number of quarters sum up to 695 cents)

From 1), we can isolate y: y = 38 - x, and place that value in the second equation:

10x + 25y = 695

10x + 25 (38 - x) = 695

10x + 950 - 25x = 695, then we subtract 950 on both sides and simplify

-15x = -255

x = 17

So, Jenna had 17 dimes.

y = 38 - x, so y = 38 - 17 = 21

And she had 21 quarters.

Answer:

$1.10

Step-by-step explanation:

1 ft = 0.3048 m

3 ft = 3 * 1 ft = 3 * 0.3048 m = 0.9144 m

$1.20/m * 0.9144 m = $1.09728

Answer: $1.10

Answer:

$ 1.08

Step-by-step explanation:

1 feet = 12 inches

so, 3 feet = 12 x 3 = 36 inches

1 metre = 40 inches

Cost of 1 m of fabric = $ 1.20

cost of 40 inches of fabric = $ 1.20

Cost of 1 inch of fabric = $ 1.20 / 40 = $ 0.03

Cost of 36 inches of fabric = $ 0.03 x 36 = $ 1.08

Thus, the cost pf 3 feet fabric is $ 1.08

Answer: [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

We need to remember that equivalent fractions are  defined as fractions whose numerators and denominator are different but both fractions represent the same value.

To find an equivalent fraction, we must multiply the numerator and the denominator by the same number (Which must be a nonzero whole number).

In this case, to find a fraction equivalent to [tex]\frac{1.5}{9}[/tex],  with a whole number in both numerator and the denominator, we can multiply the numerator and the denominator by 2. Then you get:

[tex]\frac{1.5*2}{9*2}=\frac{3}{18}[/tex]

Reducing the fraction, you get:

[tex]=\frac{1}{6}[/tex]

the simplified whole number fraction equivalent is 1/6.

To find a fraction equivalent to 1.5 over 9 with a whole number in both the numerator and the denominator, first convert the decimal in the numerator to a fraction by expressing it as 1.5 or 15/10. Then, you can write the original fraction as (15/10)/9 which simplifies to 15/90 by multiplying the numerator and the denominator by 10. Finally, you simplify the fraction by dividing both numerator and denominator by their greatest common divisor, which is 15 in this case. Thus, the simplified whole number fraction equivalent is 1/6.

The statement most accurately describes the figure is AB > DB ⇒ A

Step-by-step explanation:

* Lets describe the figure

- AD intersect EC at point B

- There are two triangles ABE and DBC

- B is the mid-point of EC

- AD bisects EC

- EB = BC

- AE = DC

- m∠AEB = 30°

- m∠DCB = 27°

∵ The measure of angle AEB is greater than the measure of

   angle DCB

∴ The opposite side to the angle AEB is longer than the opposite

   side of angle DCB

∵ AB is the opposite side to angle AEB

∵ BD is the opposite side to angle DCB

∴ AB is longer than BD

∴ AB > DB

Step-by-step explanation:

[tex]A = \frac{h_b b}{2}[/tex]

[tex]38.4 = \frac{12.8_b b}{2}[/tex]

[tex]b = 2\frac{A}{h_b}[/tex]

[tex]b = 2\frac{38.4}{12.8}[/tex] = 6

The total space enclosed by the three boundaries of the triangle is called the area of the triangle.

The length of the base of the triangle is 6 cm.

A triangle has an area of 38.4 cm2.

The height of the triangle is 12.8 centimeters.

The total surface or space enclosed by the three boundaries of the triangle is called the area of the triangle.

The formula to calculate the area of the triangle is given by;

[tex]\rm Area \ of \ the \ rectangle = \dfrac{1}{2} \times Base \times Height\\\\[/tex]

Substitute all the values in the formula;

[tex]\rm Area \ of \ the \ triangle= \dfrac{1}{2} \times Base \times Height\\\\\rm 38.4 = \dfrac{1}{2} \times Base \times 12.8\\\\ Base = \dfrac{38.4 \times 2}{12.8}\\\\Base = 3 \times 2\\\\Base = 6 \ cm[/tex]

Hence, the length of the base of the triangle is 6 cm.

To find the time for Car X to be 5 laps ahead of Car Y, we calculate the difference in laps completed per minute (0.25 laps) and divide the target difference (5 laps) by this rate, which gives us 20 minutes.

The question asks how long it will take for Car X to be 5 laps ahead of Car Y if Car X makes one lap every 60 seconds and Car Y every 80 seconds. To solve this, we need to find the difference in laps completed by the two cars over time, until Car X is 5 laps ahead. Since Car X is the faster car, it takes one lap less time than Car Y to complete a lap.

First, we find out how many laps Car X completes more than Car Y in one minute:

The difference in the number of laps per minute is 1 lap - 0.75 laps = 0.25 laps per minute for Car X compared to Car Y.

Next, we calculate the time it will take for Car X to be 5 laps ahead:

Therefore, it will take 20 minutes for Car X to be 5 laps ahead of Car Y.

I would say the correct answer is 2^3 • 5 • 11

Step-by-step explanation:

To find the prime factors, you start by dividing the number by the first prime number, which is 2. If there is not a remainder, meaning you can divide evenly, then 2 is a factor of the number. Continue dividing by 2 until you cannot divide evenly anymore. Write down how many 2's you were able to divide by evenly. Now try dividing by the next prime factor, which is 3. The goal is to get to a quotient of 1.Here are the first several prime factors: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29...

Let's start by dividing 440 by 2

440 ÷ 2 = 220 -  No remainder! 2 is one of the factors!

220 ÷ 2 = 110 -  No remainder! 2 is one of the factors!

110 ÷ 2 = 55 - No remainder! 2 is one of the factors!

55 ÷ 2 = 27.5 - There is a remainder. We can't divide by 2 even anymore. Let's try the next prime number

55 ÷ 3 = 18.3333 - This has a remainder. 3 is not a factor.

55 ÷ 5 = 11 - No remainder! 5 is one of the factors!

11 ÷ 5 = 2.2 -There is a remainder. We can't divide by 5 evenly anymore. Let's try the next prime number

11 ÷ 7 = 1.5714 - This has a remainder. 7 is not a factor.

11 ÷ 11 = 1 - No remainder! 11 is one of the factors!

If we put all of it together we have the factors 2 x 2 x 2 x 5 x 11 = 440. It can also be written in exponential form as 2^3 x 5^1 x 11^1.

The equation of the line in to point slope form is equal to

[tex]y-20=5(x-2)\\ y=5x-10+20\\ y=5x+10[/tex]

therefore

[tex]C(x)=5x+10[/tex]

step 3

For the interval ----> (6,∞]

[tex]x> 6[/tex]

[tex]C(x)=50[/tex]

Answer:

C(x)=[tex]15, 0\leq x\leq 2[/tex]

        [tex]5x+10, 2<x\leq 6[/tex]

          [tex]50, [/tex] 6<x≤∞

Step-by-step explanation:

C(x) represents the monthly cost in dollars in terms of x, the number of gigabytes used in a month

Lets find C(x) on each interval (for every line graph)

first interval 0 to 2

the value of y is 15 on the interval 0 to 2

Its horizontal line . So equation is c(x)=the constant y value

[tex]C(x)= 15, 0\leq x\leq 2[/tex]

Second interval 2 to 6

Pick two points to get the equation of that line

(3,25) and (6,40)

[tex]slope = \frac{y_2-y_1}{x_2-x_1} =\frac{40-25}{6-3} =5[/tex]

Equation of the line is using m=5 and (3,25)

[tex]y-y1=m(x-x1)[/tex]

[tex]y-25=5(x-3)[/tex]

[tex]y-25=5x-15[/tex]

[tex]y=5x+10[/tex]

[tex]C(x)= 5x+10, 2<x\leq 6[/tex]

Now we look at the third interval

6 to infinity

For the third graph , the value of y is 50 (constant)

It is a horizontal line

So [tex]C(x)= 50, [/tex] 6<x≤∞

We got three equations for C(x)

C(x) is a piecewise function

C(x)=[tex]15, 0\leq x\leq 2[/tex]

        [tex]5x+10, 2<x\leq 6[/tex]

          [tex]50, [/tex] 6<x≤∞

Answer:

100

Step-by-step explanation:

100% of a number + 30% of a number is 130% of a number.

This means 130 = 1.3x.

Now we simplify:

130=1.3x

/1.3   /1.3

100=x

x=100

Therefore, the number is 100.

The unknown number is 100.

Given that, 30% of a number is added to the number, the result is 130.

The term "percentage" was adapted from the Latin word "per centum", which means "by the hundred". Percentages are fractions with 100 as the denominator. In other words, it is the relation between part and whole where the value of the whole is always taken as 100.

Let the unknown number be x.

30% of x+x=130

⇒0.3x+x=130

⇒1.3x=130

⇒x=100

Therefore, the unknown number is 100.
