Given,
Two students in Mrs. Johnson's preschool class are stacking blocks:
The height of Reece's block = 4 cm
The height of Maddy's block = 9 cm
We have to find the height of the stacks when they are same height for the first time.
Here,
We have to find the least common multiple.
Least Common Multiple (LCM):
The smallest number that is a multiple of both of two numbers is called the least common multiple.
So here,

How long will it take for a $4000 investment to grow to $5780 at an annual rate of 4%, compounded quarterly? Assume that no withdrawals are made. Do not round any intermediate computations, and round your answer to the nearest hundredths.
The working equation when dealing with problems regarding compounded interest is
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]where A is the future value, P is the principal value, r is the annual rate, and n is the number of compounding periods.
The problem compounds quarterly, hence, we have n = 4.
We derive the working equation to solve for t, as follows:
[tex]\begin{gathered} \frac{A}{P}=(1+\frac{r}{n})^{nt} \\ \ln (\frac{A}{P})=\ln ((1+\frac{r}{n})^{nt}) \\ nt\ln ((1+\frac{r}{n}))=\ln (\frac{A}{P}) \\ t=\frac{\ln (\frac{A}{P})}{n\ln ((1+\frac{r}{n}))} \end{gathered}[/tex]Substitute the values of A, P, n, and r on the derived equation above and solve for t, we get
[tex]\begin{gathered} t=\frac{\ln (\frac{5780}{4000})}{4(\ln (1+\frac{0.04}{4}))} \\ t=\frac{\ln (1.445)}{4(\ln (1.01))} \\ t=\frac{0.368}{4(0.00995)} \\ t\approx9.25 \end{gathered}[/tex]Therefore, the $4000 investment grows to $5780 in 9.25 years.

-27 = -w/5 solve for w and simplify as much as possible and put the anwser
Answer:
w = 135
Step-by-step explanation:
-27 = -w/5
multiply both sides by 5:
5(-27) = 5(-w/5)
-w = 135
divide both sides by -1:
-w/-1 = 135/-1
w = 135
The value of w is 135 in the equation -27 = -w/5 .
We are provided with the equation mentioned below:
-27 = -w/5
As per the question we have to simplify and solve this above mentioned equation. To simplify this provided equation we will follow the steps mentioned below:
-27 = -w/5 equation 1
On multiplying both the sides of equation 1 with 5, we will get
(-27) × 5 = (-w/5) × 5
- 135 = -w equation 2
On multiplying both the sides of equation 2 with -ve sign, we will get
w = 135
Thus, we can write that the value of w is 135.

A chef had to fill up 4⁄6 of a container with mashed potatoes. He ended up using 3 2⁄4 pounds of mashed potatoes. How many pounds would he use if he had to fill up the entire container?
5.25 pounds of mashed potatoes is required to fill the container.
How Many Pounds to Fill the ContainerIn the question, we were told the container was 4/6 filled and the chef used 3 2/4 pounds which is equal to 14/4 pounds of mashed potatoes.
In doing this, we are calculating the volume of the container.
Let's equate this and find how many pounds will fill the container.
[tex]\frac{4}{6}fill = \frac{14}{4} pounds\\ 1 fill = x pounds[/tex]
Let's cross multiply both sides and solve for x.
[tex]\frac{4}{6}fill = \frac{14}{4} pounds\\1 = x pounds\\x = \frac{1 * \frac{14}{4} }{\frac{4}{6} }\\x = \frac{21}{4} = 5.25 pounds[/tex]

His lifetime earnings when he retires at the age of 68 is $2,817,385.1728.
The total number of years Demarcus will work is 68 - 24 = 44 years.
Now, there are about 52.1429 weeks per year; therefore, the number of weeks in 44 years will be:
44 years × 52.1429 weeks/year = 2294.2876 weeks
We are also told that Demarcus gets paid once every two weeks; this means the number of payments made in 44 years will be:
2294.2876 / 2 = 1147.1438 payments
Since each payment is worth $2,456.00, the total amount earned from 1147.146 payments will be:
1147.146 payments × 2456 per payment = $2,817,385.1728
Hence, Demarcus' lifetime earnings if he retires at the age of 68 will be $2,817,385.1728.

Given the figure below, find the values of x and z.
(7x + 73)°
(10x + 22)
In the given figure,
(7x + 73) + (10x + 22) = 180 ........(Because they are linear pair)
⇒ 7x + 73 + 10x +22 = 180
⇒ 17x + 95 = 180
⇒ 17x = 180-95
⇒ 17x = 85
⇒ x = 85/17
⇒ x = 5
Now, 7x +73 = z ....................(Because they are vertically opposite angles)
⇒ 7 x 5 + 73 = z
⇒ z = 35 + 73
⇒ z = 108°
What are vertically opposite angles and linear pairs?Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal. These are referred to as vertical angles at times.A linear pair of angles in geometry is a pair of neighboring angles created by the intersection of two lines. When two angles share a vertex and an arm but do not overlap, they are said to be adjacent angles. Due to their formation on a straight line, the linear pair of angles are always complementary. So, the total of two angles in a pair of lines is always 180 degrees.

What is the End behavior of the graph?The end behavior of the graph of a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity.
Now, we see from the graph that as x approaches a larger value, y values are getting increasingly negative. This means that as x approaches negative infinity, the values of y approach negative infinity.
In a similar approach, we can see that as the values of x approach positive infinity, the values of y also approach positive infinity.
Thus, we can say that option D is correct.

Answer: Equation is x+45 = 90
It solves to x = 45
Explanation:
The two angles are complementary, which by definition means they join together to form a right angle. The two pieces x and 45 add to 90 degrees.
To solve the equation x+45 = 90, we subtract 45 from both sides to get x = 45.
As a check x+45 = 45+45 = 90.
