A mother gives birth to a 9 pound baby. Every 2 months, the baby gains 4 pounds. If x is the age of the baby in months, then y is the weight of the baby in pounds.

Answer:

9

Step-by-step explanation:

35(a) / 7 = 5

28(b) / 7 = 4

a + b = 35 + 28

35 + 28 = 63

63 / 7

= 9

Answer:

Look at the picture.

The solution to the given proportion (x-1)/5 = (x-1)/2 is equal to x = 1.

To solve the proportion (x-1)/5 = (x-1)/2, we need to find the value of x that satisfies the equation. Cross-multiplication is a common method used to solve proportions.

First, cross-multiply the equation:

2(x - 1) = 5(x - 1)

Now, distribute the values on both sides:

2x - 2 = 5x - 5

Next, isolate the variable x on one side of the equation. Let's move all terms containing x to the left side of the equation by subtracting 2x from both sides:

2x - 2 - 2x = 5x - 5 - 2x

-2 = 3x - 5

Now, let's move the constant term (-5) to the other side of the equation by adding 5 to both sides:

-2 + 5 = 3x - 5 + 5

3 = 3x

Finally, to find the value of x, divide both sides by 3:

3/3 = 3x/3

1 = x

Answer:

[tex]21 \frac{1}{3}[/tex] fit into the product

Step-by-step explanation:

so you want to convert [tex]2 \frac{2}{3}[/tex] into a fraction by multiplying 2 by 3 and adding it to the 2. This will give you (3 * 2) = 6 => 6+2=8 which is the numerator. So the fraction becomes [tex]\frac{8}{3}[/tex] and since the two fractions are equal they both become this. So now you have [tex]\frac{8}{3} * \frac{8}{3}[/tex] which can be calculated by multiplying the numerators and denominators. This gives you [tex]\frac{8*8}{3*3} = \frac{64}{9}[/tex]. Now this just gives you the product but the question is asking you how many one thirds is the product. This is essentially saying how many 1/3 fit into the product or in other words what is the product divided by 1/3. This gives you the equation [tex]\frac{64}{9} \div \frac{1}{3}[/tex] which can be calculated by changing the sign to multiplication and flipping the second fraction (1/3 => 3/1) This gives you the equation [tex]\frac{64}{9} * \frac{3}{1} = \frac{64 * 3}{3 * 3} = \frac{64}{3}[/tex]. I rewrote the 9 as 3 * 3 in the equation so you can see that we can just cancel out the 3. Since if have a number and multiply it by "x" and divide by "x" you just have the original number. So now you have 64/3 which simplifies to [tex]21 \frac{1}{3}[/tex]

Step-by-step explanation:

The value of x is 1.56ft.

The Pythagoras theorem states that the sum of the squares of the base and height is equal to the square of the hypotenuse of the right-angle triangle.

If p is the height, b is the base and h is the hypotenuse then according to the Pythagoras theorem

p²+b²=h²

Here given that the radius of the circle is r=2.1 ft

the perpendicular distance from the center of the circle to the line =1.4ft

that perpendicular line will bisect the line of length 2x.

Foe which each half of the line will be x.

Applying Pythagoras theorem in the right-angle triangle,

1.4²+x²=2.1²

⇒1.96+x²=4.41

⇒x²= 4.41-1.96

⇒x²= 2.45

⇒x= 1.56 ft

If the perpendicular from chord is x, the length of cord is 11.3 and diameter be 15.5 then the value of x is 4.54.

Given Perpendicular from center to chord is x. The length of cord be 11.3 and the diameter be 15.5.

Perpendicular means a line on other line making an angle of 90 degrees. Cord is the length of line joining two points on a circle and is different from radius or diameter. We know that the formula of calculating the length of chord is as under:

l=[tex]2\sqrt{r^{2} -d^{2} }[/tex]

now put the value of l=11.3 and r=15.5/2=7.25

11.3=[tex]2\sqrt{7.25^{2} -x^{2} }[/tex]

11.3/2=[tex]\sqrt{52.5625-x^{2} }[/tex]

5.65=[tex]\sqrt{52.5625-x^{2} }[/tex]

squaring both sides

[tex]5.65^{2} =52.5625-x^{2}[/tex]

31.9225=52.5625-[tex]x^{2}[/tex]

Answer:

The amount of gross profit earned by Abbey Co. on the above transactions is $7,554.00

Step-by-step explanation:

What is the gross profit of Abbey Co?

Note that after sales of goods of $29,300 whose cost is $20,510 to Gomez Co, Gomez returned goods whose selling price is $2,500 and cost originally $1,800 to Abbey Co.

The implication of such goods returned is that $2,500 would be deducted from selling price and $1,800 would be deducted from cost of goods sold.

selling price=$29,300-$2,500

selling price=$26,800.00

cost of goods sold=$20,510-$1,800

cost of goods sold=$18,710.00

Note again that Gomez paid the invoice within the discount period, which means that net sales is the selling price of $26,800.00  minus 2% discount(2/15 means a discount of 2% is available if credit sales is settled in cash within the first 15 days of making sales0

net sales=$26,800.00*(1-2%)

net sales=$26,264.00

The gross profit is net sales minus the cost of goods sold

gross profit= $26,264.00-$18,710.00

gross profit=$7,554.00

Arianna can travel 960 mi in 16 hours.

Speed is defined as the rate of change of position of an object in any direction.

Given that, Arianna drove 180 miles in 3 hours.

As we know, Speed is the ratio of distance to the time in which the distance was covered.

Speed = distance/time

Ariana's speed = 180/3 = 60 mi/hr

Therefore, time taken by her to travel 960 mi = 960/60 = 16 hr.

Based on the calculations, the formula of this sinusoidal function is equal to f(x) = 6cos(2x) + 4.

Mathematically, the standard equation of a cosine function is given by:

y = Acos(Bx - C) + D

Where:

For the amplitude, we have:

A = maxline - midline

A = 10 - 4

Amplitude, A = 6.

Since the maxline to the midpoint is euqal to π/4, we have:

¼ × P = π/4

4P = 4π

P = π

For the value of B, we have:

B = 2π/P

B = 2π/π

B = 2.

Since there isn't any phase shift, the value of C is equal to zero (0) and D is equal to 4.

Next, we would substitute the parameters into the cosine function:

y = Acos(Bx - C) + D

Answer:

  35

Step-by-step explanation:

The equations will be "consistent" when they describe lines that are not parallel.

The slope of a line whose equation is written in this form is the opposite of the ratio of the y-coefficient to the x-coefficient:

  line 1 slope = -8/20 = -2/5

  line 2 slope = -14/35 = -2/5

These lines have the same slope, so will be parallel unless they have the same y-intercept.

The y-intercept of each line is the ratio of the constant to the y-coefficient:

  line 1 y-intercept = 20/20 = 1

  line 2 y-intercept = k/35

We want these lines to have the same y-intercept so that they are not inconsistent. This requires ...

  k/35 = 1

  k = 35

For the equations to be consistent, we must have k = 35.

Additional comment

Linear equations are generally categorized as "consistent" or "inconsistent," and "dependent" or "independent."

Equations are "inconsistent" if there are no values of the variables that satisfy all of the equations. They are "dependent" if they describe exactly the same relation between the variables. "Consistent" equations may be "dependent" (describing the same line, as here), or "independent" (describing lines with different slopes.)
