The complete options to choose from in order to explain her mistake are not shown, therefore I'll solve the problem generally.
To solve 1.8/0.3 easily we multiply but numerator and denominator by 10
(1.8*10)/(0.3*10) = 18/3 = 6
The dividend and the divisor should have been multiplied by 10 and the decimal point in the quotient should have been shifted to the right by Becca.
Both the dividend and the divisor must be changed such that there are no decimal places in the divisor before dividing decimals. Becca made a mistake by not taking this change into account.
Becca needed to multiply both the dividend (1.8) and the divisor (0.3) by 10 to get rid of the decimal places in order to divide 1.8 by 0.3 correctly. As a result, the issue would change to 18 3.
When the division is done properly, we see that 18 3 equals 6, leaving no residual.
Therefore, Becca made a mistake by failing to multiply both the dividend and the divisor by 10.

Carla, Rachel, and Jack each throw a baseball into the air. Carla's baseball's height is represented in the graph below. The vertical axis represents the ball's height in feet, and the horizontal axis represents time in seconds. Rachel recorded the height of her baseball each second after her throw in the table below. The height of Jack's baseball is represented by the function h(1) =- x2 + 5x + 6, where h(t) is the height of the ball in feet after t seconds.

Find the area of a square that has a side length of 4.8 cm.
A=23.04cm² , A=a2=4.82=23.04cm²
Answer: 23.04 cm.
Step-by-step explanation:
To find the area of something, we use the equation l x w, or length x width.
A square has 4 sides, and all 4 sides are equal. If the length of a square is 4.8, then the width is also 4.8 since all 4 sides of a square are equal.
Since we're using the equation l x w to find the area of the square, we have to multiply 4.8 x 4.8.
4.8 x 4.8 = 23.04.
Therefore, the area of the square is 23.04 centimeters!

A rectangular prism has a base with an area of 13 square units and a volume of
109.2 cubic units. The equation shown gives the height, h, in units, of the prism.
13h = 109.2
What is the height, in units, of the prism?
Answer:
Isolate the variable and simplify.
Step-by-step explanation:
13h = 109.2
h = 109.2 ÷ 13
h = 8.4
Your answer would be 8.4 units.
Don't forget units! :)

Which function has a greater rate of change? Function A: x 1.5 2.5 3.5 4.5 5.5 y 5 0 –5 –10 –15 Function B: y = –4.5x + 15 Function A has a rate of change of –5 and Function B has a rate of change of –4.5, so Function A has a greater rate of change. Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function A has a greater rate of change. Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function B has a greater rate of change. Function A has a rate of change of –5 and Function B has a rate of change of –4.5, so Function B has a greater rate of
Answer:
Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function B has a greater rate of
Step-by-step explanation:
Function A:
[tex]\begin{array}{cccccc}x & {1.5} & {2.5} & {3.5} & {4.5} & {5.5} \ \\ y & {5} & {0} & {-5} & {-10} & {-15} \ \end{array}[/tex]
Function B:
[tex]y = -4.5x + 15[/tex]
Required
Which has a greater rate of change
The rate of change of function A is calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex](x_1,y_1) = (1.5,5)[/tex]
[tex](x_2,y_2) = (2.5,0)[/tex]
So, we have:
[tex]m = \frac{0-5}{2.5 - 1.5}[/tex]
[tex]m = \frac{-5}{1}[/tex]
[tex]m = -5[/tex]
For function B
The general function is:
[tex]y = mx + b[/tex]
Where
m is the rate of change
By comparing [tex]y = mx + b[/tex] to [tex]y = -4.5x + 15[/tex]
[tex]m = -4.5[/tex]
So, we have that:
Function A has a rate of -5; function B has a rate of -4.5.
By comparison: -4.5 is greater than 5
Hence, function B has a greater rate.
Mirela has a rectangular piece of paper with an area of 0.35 m2. She cuts the paper into small rectangles with areas of 700 cm2. What is the maximum number of rectangles she can cut?
Answer:
The maximum number of rectangles that Mirela can cut is 5
Step-by-step explanation:
First, you must ensure that all the measurements are the same units.
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:
a ⇒ b
c ⇒ x
where a, b and c are known values and x the value to calculate. So:
[tex]x=\frac{c* b}{a}[/tex]
The direct rule of three is the rule applied in this case where there is a change of units.
To perform this conversion of units, you must first know that 1 m² = 10,000 cm². So, if 10,000 cm² is 1 m², how many cm² equals 0.35 m²?
[tex]cm^{2} =\frac{0.35 m^{2} *10000 cm^{2} }{1 m^{2} }[/tex]
cm²= 3500
Now, to calculate the maximum number of rectangles that Mirela can cut you divide the total area of the paper by the area of each rectangle:
3500 cm² ÷ 700 cm²= 5
The maximum number of rectangles that Mirela can cut is 5

a person bikes 2 1/2 miles at a constant rate in 1/8 of an hour what distance , does the person bikes in an hour.
Answer:
20 miles
Step-by-step explanation:
We are given that
Person traveled total distance by bike=2 1/2 miles
Person traveled total distance by bike==[tex]2+\frac{1}{2}=2.5miles[/tex]
Time taken by person ,t=1/8 hour
We have to find the distance traveled by person bike in an hour.
We know that
Rate==[tex]\frac{Distance}{time}[/tex]
Using the formula
Rate=[tex]\frac{2.5}{\frac{1}{8}}[/tex]miles/hr
Rate=20mph
In 1 hour person bike traveled distance=20 miles

Answer:
Question 3: M = -2, B = 1
Question 4: M = [tex]\frac{2}{5}[/tex], B = -6
Question 5: M = 1, B = -5
Question 6: M = [tex]\frac{1}{3}[/tex], B = 4
Step-by-step explanation:
Question 3 explanation: 2x + y < 1 ⇒ y < -2x + 1 ⇒ M = -2, B = 1
Question 4 explanation: 2x - 5y ≥ 30 ⇒ -5y ≥ -2x + 30 ⇒ y ≤ [tex]\frac{2}{5}[/tex]x - 6 ⇒ M = [tex]\frac{2}{5}[/tex], B = -6
Question 5 explanation: x - y > 5 ⇒ -y > -x + 5 ⇒ y < x - 5 ⇒ M = 1, B = -5
Question 6 explanation: 2x - 6y ≤ -24 ⇒ -6y ≤ -2x - 24 ⇒ y ≥ [tex]\frac{1}{3}[/tex]x + 4 ⇒ M = [tex]\frac{1}{3}[/tex], B = 4

Answer:
3.375 in³
Step-by-step explanation:
1) V = l x w x h
2) Since a cube has all equal sides, then our equation would be V = 1.5³
3) V = 1.5³ = 3.375 in³
Answer:
3.375 in^3.
Step-by-step explanation:
All sides have the same length so the volume = 1.5^3
= 3.375 in^3.

Answer:
11 weekends.
Step-by-step explanation:
470.80 = 58.30 + 37.50x
-58.30 -58.30
412.50 = 37.50x
divide both sides by 37.50, and x = 11
