Elijah's puppy weighs 20 ounces. If he weighed 15 ounces at the last visit to the veterinarian's office, what is the percent increase in the puppy's weight rounded to the nearest whole number?​

Answer:

The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and

b (=y) for 5 weeks.

Step-by-step explanation:

Every week Jim runs 8 miles and bikes 12 miles.

Let the week be represented by w , running miles by r and biking miles by b

therefore

1w= 8r + 12 b

Multiplying both sides by 5

5(1w= 8r + 12 b)

5(1w) = 5(8r + 12 b )

5w= 40r + 60b

Jim runs 40 miles and bikes 60 miles in 5 weeks

The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and

b (=y) for 5 weeks.

The answer is written in the form (x, y) where x is written before y in the ordered pair. We treat  running miles as x and biking miles as y.

Answer:

You need to make turn this information into slope intercept form: y = mx + b. The m is your slope, the b is your y-intercept. x and y represents the coordinates that the line passes through. Make y = 1, make m = -2, and make x = 2, and you will get: 1 = -2(2) + b. When you simplify, you get 1 = -4 + b, add 4 to both sides and you'll get 5. So my equation is y = -2x + 5. Remember the -2 came from the slope! To get b, substitute the (2,1) in for (x,y) in the equation.

Answer:

[tex] x = \sqrt {y}{b} [/tex]

Step-by-step explanation:

Given the algebraic expression;

[tex] y = bx^{2} [/tex]

To make x the subject of formula.

We would divide both sides by b;

[tex] \frac {y}{b} = x^{2} [/tex]

Taking the square root of both sides, we have;

[tex] x = \sqrt {y}{b} [/tex]

Answer:

[tex]y = b {x}^{2} \\ \frac{y}{b}= {x}^{2} \\ x = \sqrt{ \frac{y}{b} } [/tex]

Answer:

6.9 inches

Step-by-step explanation:

From the above question:

Scale =

1 inch = 1.5 inches

Original drawing = 4.6 inches

Hence:

1 inch = 1.5 inches

4.6 inches = x

Cross Multiply

x = 4.6 × 1.5 inches

x = 6.9 inches.

Therefore, the length of the enlargement = 6.9 inches

Answer:

r = 1

Step-by-step explanation:

We know that x and y are proportional, with the the equation y = rx representing the proportional relationship. Where r = constant of proportionality

Thus the constant of proportionality would be:

r = y/x

Using any of the given pair of values from the table, say (5.8, 5.8),

r = 5.8/5.8

r = 1

Answer:

12 inches

Step-by-step explanation:

Picture of question is in the attachment below :

Answer:

m∠1= 157°

m∠2= 23°

m∠3= 157°

m∠4= 23°

m∠5= 157°

m∠6= 23°

m∠7= 157°

Step-by-step explanation:

Given that:

m∠8 = 23°

m∠6= 23 ; m∠8 = m∠6 (vertically opposite angles)

m∠5 = m∠7 ( vertically opposite angles)

m∠5 + m∠6 + m∠7 + m∠8 = 360° (sum of angles at a point)

x + 23 + x + 23 = 360

46 + 2x = 360

2x = 360 - 46

2x = 314

x = 314 / 2

x = 157

Hence,

m∠5 = m∠7 = 157°

m∠1 = m∠5 = 157° corresponding angles

m∠4 = m∠8 = 23° corresponding angles

m∠3 = m∠7 = 157° corresponding angles

m∠6 = m∠2 = 23° corresponding angles

Answer:

A) f(2) = 20

B) g(2) = 2

C) f(2) + g(2) = 22

Step-by-step explanation:

For part A, you change the x to become 2, to have the equation of 5(2)+10. You then solve in order to get 20.

For part B, I'm not exactly sure what the equation is, but you do the same thing for part A. Since there is no x variable then just keep the answer you have. Meaning it is 2

Finally, part C is adding your answers from part A and part B to get the final answer of 22.

Answer:

N(22, 2)

Step-by-step explanation:

Suppose that it takes a worker aged over 55 an average of 22 weeks to find a new job with a standard deviation of 2 weeks. The distribution is bell shaped. We summarize the

Mean time of finding a new job : μ = 22

Standard deviation ; σ = 2

Since the distribution give is bell shaped ; this defines a distributon usually described as normal which in standardized form has a mean of 0 and standard deviation of 1.

Hence, the distribution is approximately normal with mean of 22 and standard deviation of 2

X ~ N(22 , 2)

Answer:

3. Yes, because 160 / 4 = 40 and 120 / 3 = 40.

4. 10, because 24 / 12 = 2 and 20 / 2 = 10

Answer:

3. David and Aryana use their phones at the same rate.

4.10 parts of water to 20 parts of cornstarch.

Step-by-step explanation:

3. First, you have Aryana who uses 160 mins in 4 days. Then there is David who has 120 minutes in 3 days. You want to divide the minutes by days to see  how many minutes per day they use their phone. 160/4=40 120/3=40. David and Aryana use their phones at the same rate.

4. First, you have 24c to 12w (c is cornstarch and w is water). If you want to find 20c and what w is, you need to make c into a smaller number. What I mean is that you need to divide the equation as low as it can go, this one happening to be 12. So you do 24 to 12/12 = 2c to 1w. You then multiply the number back up to twenty. so 2*10 = 20 1*10=10. Your final answer is 10 parts of water to 20 parts of cornstarch.
