Becca solved the division problem 1.8 ÷ 0.3. Her work is shown below. Long division problem showing one and eight-tenths divided by three-tenths equals six-tenths Part A Use the drop-down menus to explain the mistake Becca made. Becca should have the dividend and the divisor by and moved the decimal point in the quotient to the .
Answers
Answer and Step-by-step explanation:
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.

The binomial (x+2) is a factor of ?
1). 2x^{2} -5+3
2). x^{2} +5x+18
3). x^{3} +5x^{2} + 18
4). x^{3} +5x+18
Answers
Answer:
4). [tex] x^{3} +5x+18 [/tex]
Step-by-step explanation:
The binomial (x+2) is a factor of [tex] x^{3} +5x+18. [/tex]
Since, (x + 2) is a factor.
So, x = - 2 is a root
Plug x = - 2 in [tex] x^{3} +5x+18 [/tex]
We find:
[tex] x^{3} +5x+18 [/tex]
[tex] =(-2)^{3} +5(-2)+18 [/tex]
[tex] =-8 - 10+18 [/tex]
[tex] = - 18+18 [/tex]
[tex] = 0 [/tex]
Since, at x = - 2 the value of the expression [tex] x^{3} +5x+18 [/tex] becomes zero.
Therefore, (x + 2) is a factor of [tex] x^{3} +5x+18 [/tex]

Caroline rolls a fair dice 480 times. How many times would Caroline expect to roll a six?
PLSSS ANSWER
Answers
So divide 480/6= 80
80 times for each number, 80 for 6
Since the dice is fair, each number (1 through 6) has an equal probability of appearing on each roll. The probability of rolling a six on any one roll is 1/6. Hence, 1/6 times of 480 is 80 times.
What is probability ?Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to occur.
To find the expected number of times Caroline would roll a six, we can use the formula:
Expected number of occurrences = Probability of occurrence x Number of trials
In this case, the probability of rolling a six is 1/6, and the number of trials is 480. Therefore, the expected number of times Caroline would roll a six is:
Expected number of times = (1/6) x 480 = 80
Therefore, Caroline would expect to roll a six 80 times out of 480 rolls.

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller number is 50
Answers
Answer: Smaller number = 6
Larger number = 20
Step-by-step explanation:
Let the smaller number be x.
Let the larger number be y.
Three times a larger number is 30 more than 5 times a smaller number. This will be:
3 × y = (5 × x) + 30
3y = 5x + 30 ...... i
The sum of the larger number and 5 times the smaller number is 50. This will be:
y + 5x = 50 ...... ii
From equation ii
y + 5x = 50.
y = 50 - 5x ...... iii
Put the value of y = 50 - 5x into equation i
3y = 5x + 30
3(50 - 5x) = 5x + 30
150 - 15x = 5x + 30
150 - 30 = 5x + 15x
120 = 20x
x = 120/20
x = 6
The smaller number is 6
Note that y + 5x = 50
y + 5(6) = 50
y + 30 = 50
y = 50 - 30
y = 20
The bigger number is 20

Sasha paid $68 for a painting frame during a 20% sale event. Find the original price of the frame.
Answers
Answer:
$68.20
Step-by-step explanation:
Answer:
85$
Step-by-step explanation:
p = original price
68 = p - 20%p
68 = p - 0.20p
68 = 0.80p
85 = p
The original price was $85.
The original price is 100%. The sales price was 20% off - subtract. So the sale price was 100% - 20% = 80%.
Incase you wanna know how I came up with the 0.80p :)

Answer:
only C is non-linear
Step-by-step explanation:
A linear equation is of the form;
y = mx + c
we have single powers of x and y; also, there is no product of x and y
Thus, we have;
a; 12x + 3y = 7
y =( -12x + 7)/3
this shows we have a linear equation
b. y + x = 4x + 5
y = 4x-x + 5
y = 3x + 5
This is a linear equation
c. y = 8/x^2
This is non-linear; we already have one power of x as 2

Write an equation, in standard form, using the following given info: M = 10
and it passes through the point (6,2) *
-10x + y = -58
-10x + y = 58. -10x - y = -58
10x + y = -58
Answers
Given:
m = 10
The line passes through the point (6,2).
To find:
The equation of line in the standard form.
Solution:
If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passes through the point (6,2) and m = 10. So, the equation of line is
[tex]y-2=10(x-6)[/tex]
[tex]y-2=10x-60[/tex]
[tex]y-10x=-60+2[/tex]
[tex]-10x+y=-58[/tex]
Therefore, the correct option is A.
