Answer:
because 4 is being multiplied by 500 which has two zeros because it is a multiple of 100
Step-by-step explanation:
Answer:
Because when you multiply 500 by 4 you start with the first 0. 4x0 is 0, now you move on to the second 0. 4x0 is 0, so that one is 0 too. Now you multiply the 5. 5x4 is 20. You put the 20 first, followed by the two 0s, And you get 2,000.

Dalton is saving up money to buy a car. He deposits $10 in his savings account the 1st month. Each month after that, he deposits $5 more than the amount he deposited the previous month. Thus, Dalton's deposit is $15 the 2nd month, $20 the 3rd month, and so on. He makes his final deposit of $95 the 18th month . How much money does Dalton have in his account after these 18 deposits ?

What is the Measure of ZADB?
A
(3x + 9)
B
(2x - 4)^
D
с
Answer:
60
Step-by-step explanation:
m(ADB) + m(BDC) = 90°
(3x+9) + (2x -4) = 90°
5x + 5 = 90°
5x = 85
5x/5 = 85/5
x = 17
m(ADB) = 3x + 9
3.17 + 9 = 51 + 9 = 60
Hope this helps ^-^
Answer: 60°
Step-by-step explanation:
Looking at the figure, we know that the angles add up to 90°. We add both equations and solve for x.
3x+9+2x-4=90 [combine like terms]
5x+5=90 [subtract both sides by 5]
5x=85 [divide both sides by 5]
x=17
Now that we know x, we can plug it into ADB to find the angle.
3(17)+9 [multiply]
51+9 [add]
60
Now, we know that ADB is 60°.

Put the quadratic into vertex form and state the coordinates of the vertex. y=x^2-2x+3
Answer:
The vertex form of the quadratic: y = (x - 1)² + 2
Coordinates of vertex: (1, 2)
Step-by-step explanation:
[tex]y=x^2-2x+3\\\\y=x^2-2x+1+2\\\\y=(x-1)^2+2[/tex]
The vertex form of an equation of the parabola is: f(x) = a(x - h)² + k
where (h, k) is the vertex. So:
x - h = x - 1 ⇒ h = 1
+ k = +2 ⇒ k = 2

The length of a rectangle is 11cm more than the width. Find the dimensions of the
rectangle if the area is 60cm?
width x
lenght : x + 11
area = x * (x+11) = 60 cm²
x² + 11x - 60 = 0
Δ = 11² - 4*1*(-60) = 121 + 240 = 361 = 19²
x' = (-11 - 19) / 2 = not possible
x" = (-11 + 19) / 2 = 4
witdh = 4
lenght = 4+11 = 15

Which set of population data is the least dispersed from its mean? 2, 3, 2, 9 4, 0, 4, 0 6, 2, 2, 2 9, 3, 5, 3.
The set of data 6, 2, 2, 2 will have the least dispersion from its mean.
What will be the mean?From four sets of data, we take the mean of 6,2,2,2
[tex]\rm mean =\dfrac{ Sum \ of\ data}{Number \ of\ data}[/tex]
So the mean will be
[tex]\rm mean =\dfrac{ 6+2+2+2}{4}=\dfrac{12}{4} =3[/tex]
So the mean of the data (6,2,2,2) is 3 which has the least dispersion from its every data as compared to the other data
Thus the set of data 6, 2, 2, 2 will have the least dispersion from their mean.

Jamila is walking her small dog for a walk around her neighborhood. They travel 3/5 They travel 3/5of a mile in 40 minutes. Determine the unit rate they walk in minutes per hour.
Answer:
unit rate = 0.9 miles per hour
Step-by-step explanation:
Rate per hour of walking is calculate by = distance moved in miles/ time taken in miles
_________________________
given
distance = 3/5 of a mile = 3/5 miles
time = 40 minutes
we have to find time in hours
60 minutes = 1 hour
40 minutes = 1/60 *40 hours = 2/3 hours
thus
unit rate = (3/5 miles)/ (2/3 hours ) = (3*3)miles/(5*2) hour = 9/10 miles per hour
unit rate = 0.9 miles per hour

The area of a rectangular field is 4864 m².
If the width of the field is 64 m, what is its length?
Answer:
76 m
Step-by-step explanation:
The area of a rectangle = length × width.
If we know that the area is 4864m² and the width is 64m, we can substitute this into the formula:
4864 = length × 64
To find the length, all we have to do is divide the area by 64: length = 4864 ÷ 64 = 76 m

The ratio of y:x should be constant for any value of x and y.
[tex] \frac{y}{x} = constant[/tex]
If go over every table, you'll find that this is true for the third one and that the ratio is r=50
The table showing the proportional relationship between x and y is the third one.
What is proportional relationship?Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.
Given are four tables, giving values of x and y, we need to identify the table giving the relation between x and y which is proportional.
Table 1)
x = 1, 2, 3, 6
y = 1.5, 3, 6, 9
y/x = 1.5, 1.5, 2, 1.5 [not proportional]
Table 2)
x = 2, 4, 5, 6
y = 6, 12, 18, 21
y/x = 3, 3, 3.6, 3.5 [not proportional]
Table 3)
x = 1, 3, 4, 5
y = 50, 150, 200, 250
y/x = 50, 50, 50, 50 [proportional]
Hence, the table showing the proportional relationship between x and y is the third one.
