                 10 per minute  is 20% of normal

                       (10 / min)  =  0.2 x (normal)

Divide each side by  0.2 :        Normal  =  (10 / 0.2 min) = 50 / min

The grizzly bear's normal heart rate when not hibernating is 50 beats per minute.

I got this by using 10 beats per minute as my dividend and 20% as my divisor.

10 / 20% = 50.

To check: you can multiply 50 by 20% to get its percentage.

50 * 20% = 10

When a word problem uses a number and a percentage and is looking for the whole number, you must divide the number by its corresponding percentage. On the other hand,  when a word problem is looking for the value of the percentage where the total number and percentage is given, just multiply the two

What is the answer for this ?
REY [17]

Answer:

A

-2 < x ≤ 3 (All x values between -2 and 3; excluding -2 and including 3)

Step-by-step explanation:

I feel the answer is A because from what we know, domain is the x-intercept or x. So both C and D are not the answer because the y-intercept is not the domain, the y-intercept is the range. Next I looked at both A and B, well, if you look closely answer choice A says "excluding -2 and including 3" and choice B says "including -2 and excluding 3". I also seen on the graph that the point of (3,3) has a filled in dot and the point at (-2,-1) has an opened dot. A filled in dot always means you either have a ≥ (greater than or equal to sign) or a ≤ (less than or equal to sign). While an opened dot always means you just have < (greater than) or a > (less than) sign. So the correct answer is A!! Hope you have a fantastic rest of your day! :)))

A masonry contractor is preparing an estimate for building a stone wall and gate. He estimates that the job will take a​ 40-hour
kodGreya [7K]

Solution: Estimated time for the work is 40 hour work week.

Estimated payment to 3 laborers working 40 hours at cost $14 per hour is:

3\times 40\times 14= $1680

Estimated payment to 6 masons working 40 hours at cost $24 per hour is:

6\times 40\times 24= $5760

Estimated cost of material = $3143

Contractor wishes to make a profit of $500

Therefore, the mathematical expression that will give the estimated cost of the job is:

Cost = 1680+5760+3143+500

The estimated total cost is:

Cost =$11083

Find the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6.
DENIUS [597]

We have that    the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6. is

m=\infty

From the question we are told

Find the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6.

Where Standard form of Equation is

y=mx+c

Generally the equation for the Slope  is mathematically given as

m=\frac{y_2-y_1}{x_2-x_1}

Therefore

m=\frac{-7-1}{-6-(-6)}\\\\ m= \infty

Therefore

The slope of this line is

m=\infty
