13.65 = h + 4.88 What the answer

Answers

Answer:

h = 8.77

Step-by-step explanation:

Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Subtract 4.88 from both sides:

h + 4.88 = 13.65

h + 4.88 (-4.88) = 13.65 (-4.88)

h = 13.65 - 4.88

h = 8.77

8.77 is your answer for h.

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:

f(d) = 9(1.04)d

Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function?

Answers

Answer:

9 days

Step-by-step explanation:

1= 9*(1.04)^d

12.81/9= (1.04)^d

1.423= (1.04)^d

log(1.423)= d *log(1.04)

0.1532=d * 0.017

d= 0.1532/0.017

d=9

The reasonable domain to plot the growth function is in the interval [0,9].

Answer:

9 days

Jesse has a collection of nickels and quarters worth $5.00. She has 40 more nickels then quarters. How many coins of each type does she have?

Answers

Answer: Jesse has 50 nickels and 10 quarters

Step-by-step explanation:

set up a system of equation

q is quarters and n is nickels

q+40=n is the first equation

.05n+.25q = 5 or 5n+25q=500

solve by substitution

5(q+40)+25q=500

5q+200+25q=500

30q=300

q=10

substitute back into the original equation

10+40=n

50=n

Solve the equation.

The Emerald Bot clicks 3 times in ____ sec, and its Unit Rate is 7.5 clicks per second. Find the number of sec.

Answers

Answer: The Emerald Bot clicks 3 times in __0.4_ sec

²/₁₅ second per click × 3clicks = ²/₅ sec

Or 0.1333 × 3 = 0.3999 Round to 0.4

Step-by-step explanation: If its unit rate is 7.5 clicks per second, we can find the time, seconds per click by dividing one second by 7.5 clicks

1/7.5 = 0.13333 seconds per click.

Multiply that ²/₁₅ seconds by the 3 clicks to get the time it takes for the 3 clicks.

Which sum is equal to
8/12

Answers

Answer: 2/3

Step-by-step explanation:

For example, if we multiply the numerator and denominator of 2/3 by 4 we get. 2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.

Answer:

either 4/6 or 2/3

Step-by-step explanation:

Because 12 can be divide in half which is 6, and 8 divided by 2 is 4, so your fraction is now 4/6. if this answer isn't on the screen then you have to do it again: 4 divide by 2 is 2, and 6 divided by 2 is 3, so your fraction is now 2/3.

Please help.Find the circumference (to the nearest whole number). Use 3.14 for pi.

A.116 in
B. 88 in
C.44in
D.None of the above

Answers

B. 88in , hopefully that helps you:))

The circumference is approximately 88 inches.

The correct option is B. 88 in.

To find the circumference of a circle, we can use the formula:

C = 2πr,

where C represents the circumference and r represents the radius of the circle.

Given that the radius, r, is 14 inches, we can substitute this value into the formula:

C = 2 x 3.14 x 14.

C ≈ 87.92 inches.

Thus, the circumference is approximately 88 inches.
