Answer:

3/12 or 1/4 after simplifying

Mr. Ramirez gave his class
Angelina_Jolie [31]

Answer:

38 pages per hour

Step-by-step explanation:

Rate of reading = \frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}

By substituting the given values in the question,

Total number of pages read by Davida = 28\frac{1}{2} = \frac{57}{2}

Time taken by Davida = 45 minutes

Since, 1 minute = \frac{1}{60} hours

Therefore, 45 minutes = \frac{45}{60}=\frac{3}{4} hours

Rate of reading = \frac{\frac{57}{2}}{\frac{3}{4} }

                          = \frac{57}{2}\times \frac{4}{3}

                          = 38 pages per hour

Therefore, rate of reading by Davida is 38 pages per hour.

5) Ziegler is using paper for an art project
lord [1]

Answer:

9.5 * 10^-2 mm

Step-by-step explanation:

To find the total thickness, we proceed to add the two thickness that we have

Mathematically, this will be;

0.025 mm + 7 * 10^-2 mm

7 * 10^-2 mm = 0.07

So we have;

0.025 mm + 0.07 mm = 0.095

In scientific notation, this is 9.5 * 10^-2 mm

-2x^(3) +3=-1x^(3) -1x^(2) +1x+1
Natali5045456 [20]
-2x³ + 3 = -x³ - x² + x + 1

Add x³ to both sides, and subtract 3 from both sides.

-2x³ + x³ = -x² + x + 1 - 3

Add like terms.

-x³ = -x²+ x - 2

Move all of the (X's) to both sides, by adding x² to both sides, and subtracting x form both sides.

-x³ + x² - x = -2

~Hope I helped!~

Log3 a/3 = ??????????????????????????
Naddik [55]
We have that
<span>Log3 a/3
</span>Rewrite log3(a/3) using the change of base <span>formula

we know that
</span>The change of base rule can be used if a and b are greater than 0 and not equal to 1, and x is greater than 0<span>.
</span>so
loga(x)=<span>logb(x)/<span>logb<span>(a)
</span></span></span>Substitute in values for the variables in the change of base <span>formula
</span>
in this problem
b=10
a=3
x=a/3

log3(a/3)=[log (a/3)]/[log (3)]

the answer is
[log (a/3)]/[log (3)]

Factor the expression. 4d + 12 Enter your answers in the boxes.
Dmitry_Shevchenko [17]
4d + 12 = 4(d + 3)
Basically, you just need to determine what 4d and 12 have in common.  In this case, they both divide evenly by 4. Therefore 4 (d + 3) = 4d + 12 according to the distributive property.
