Answer:
25.07 × 5.4 = 135.378
Step-by-step explanation:
In placement of the decimal point in multiplication , first check the numbers that will multiply and count the individual decimal points in the numbers. In this case, 25.07 × 5.4 = 2 * 1 -------decimal place The answer should have 2+1 = 3 decimal places-----note the addition sign 25.07 × 5.4 = 135.378 ---------the answer has 3 decimal places The first answer is incorrect because ; 2.52 × 27.94 = 704.088 ----2 *2 = 4 , but the answer has 3 The second answer is incorrect because; 94.1 × 2.5 = 23.525 -----1 * 1= 2 decimal places, the answer has 3 The third answer is incorrect because ; 1.83 × 2.9 = 53.07--------2*1= 3 decimal places , the answer has 2
Marco takes 12 mins to drive his car down the hill to the movies and 24 mins to drive up the hill from the movies he goes to the movies Monday through Friday.How many mins does he spend driving his car to and from the movies in two weeks ?Wrote an equation to model your work
Answer:
360 minutes
Step-by-step explanation:
Given that:
Driving down the hill (d) = 12 minutes
Driving up the hill (u) = 24 minutes
Days = Monday - Friday = 5days
For 2 weeks : 2 * 5 = 10
Total time taken to drive up and down daily (T) : (12 + 24) minutes = 36 minutes
For the two weeks :
10(T)
= 10(36)
= 360 minutes
Model:
Let number of days = n
Number of minutes :
n(u + d)
2. Sara went to the store to buy 3 apples, 1 cabbage and four, 2-Liter of sodas. She has $15.47 with her.
The apples are 89 cents each and the cabbage is $1.99 each. The 2-liter of soda is $2.99 each but on sale
for 99 cents each if you purchase 4 at one time. Sales tax is $2.24 if the total is below $10.00 and $4.24 if
the total is above $11.00. How much is the total cost of the food?

What is the center and radius of the circle with the following equation:
(x - 2)²+(y+1)= 9
Answer:
Center: (2,-1), Radius: 3
Step-by-step explanation:
Given: 5n-42=12n prove: n=-6
Answer:
n=-6
Step-by-step explanation:
5n-42=12n
5n=12n+24
5n-12n=42
-7n=42
divide each side by -7
n does =-6
The required proof for n = -6 is given in the solution.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
The given equation is,
5n - 42 = 12n
Taking alike terms together we get,
5n - 12n = 42
Solving we get,
-7n = 42
Dividing both the side by -7 we get,
-7n/-7 = 42/-7
Solving we get,
n = -6
Hence we get the required proof.
Thus, the required proof for n = -6 is given in the solution.

rewrite each problem so that x appears on only one side
Answer:
x = -5/21
Step-by-step explanation:
Step 1: Write equation
2(12x - 1) = (21x - 49)/7
Step 2: Solve for x
Multiply both sides by 7: 14(12x - 1) = 21x - 49Distribute 14: 168x - 14 = 21x - 49Subtract 21x on both sides: 147x - 14 = -49Add 14 to both sides: 147x = -35Divide both sides by 147: x = -5/21If the measure of angle 2 is 48 degrees, what is the measure of angle 7?
when 24 is subtracted from the square of a number the result is five times a number what is the negative solution
Step-by-step explanation:
let the unknown be x
24 - x^2 = 5x
-x^2 - 5x + 24 = 0
(x - 3)(x + 8) =0
x = 3 (or) x = -8
if u wanna check
if you wanna check
24 - (-8)^2 =5(-8)
24 - 64 = -40
-40 = -40
since you ask for negative solution
x= -8 is a NUMBER
the solution is 5times of a NUMBER = -8 × 5 = -40
hope I got it right^^,good luck!

Line s has an equation of y=-1/7x-10. Parallel to line s is line t, which passes through the point (9,-2). What is the equation of line t?
Answer:
y = -1/7x + 5/7
Step-by-step explanation:
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = -1/7x + b
-2 = -1/7(9) + b
-2 = -9/7 + b
5/7 = b
y = -1/7x + 5/7
Best of Luck!

Given triangle ABC with coordinates A(−2, 7), B(−2, 4), and C(−4, 3), and its image A′B′C′ with A′(2, 3), B′(−1, 3), and C′(−2, 1), find the line of reflection.
The line of reflection is at y =
Answer:
y = x + 5
Step-by-step explanation:
given an obtuse scalene triangle (∆ABC) with vertices A(-2,7), B(-2,4), and C(-4,3) (representing the preimage of the reflection). And congruent triangle (∆A'B'C') with vertices A'(2,3), B'(-1,3), and C'(-2,1) (representing the image of the reflection / triangle after the reflection).
The easiest way to look at this is by taking the inverse of each point on the preimage (swapping y and x coordinates) and the adding 5 to the y and subtracting 5 from the x to get the image.
You can test this, and you will see that this will match with vertices of the image.
2/5 divided by 1/6 this is dividing fractions
Answer:
exact form: 12/5
decimal form: 2.4
mixed number: 2 2/5
hope this helps :)
Step-by-step explanation:
The required solution of the given fraction divide 2/5 by 1/6 is equal to 12/5.
Given that the fraction is divide 2/5 by 1/6.
When dividing fractions, multiply the first fraction by the reciprocal of the second fraction.
To divide 2/5 by 1/6, write it as:
(2/5) ÷ (1/6)
To find the reciprocal of 1/6, flip the fraction:
Reciprocal of 1/6 = 6/1
Now, rewrite the expression as:
(2/5) × (6/1)
Multiplying the numerators and denominators gives us:
(2 × 6) / (5 × 1) = 12/5
Therefore, 2/5 divided by 1/6 is equal to 12/5.

16.827 to the nearest whole.
Answer:
17
Step-by-step explanation:
We want to round 16.827 to the nearest whole number.
When we round a number to the nearest place value, we always look at the digit in the place value to its right.
Here, we're technically rounding to the nearest ones place, so look at the tenths place. It's an 8. Remember that we round up if the digit is 5-9 and round down if the digit is 0-4.
Since it's 8, we round up. Thus, 16.827 rounds up to 17.

4. An attorney charges $250 for a
consultation fee plus $100 per hour of
service. How many hours did he work in
order for his total bill to be $3500?
Answer:
The attorney worked for 32.5 hours in order for his total bill to be $3,500.
Step-by-step explanation:
Let's set up an equation with some variables:
[tex]h[/tex] = hours of service
[tex]T[/tex] = total bill
[tex]T=100h+250[/tex]
Plugging in our given values, we get:
[tex]3500=100h+250[/tex]
And solving for [tex]h[/tex], the hours the attorney worked, we get:
[tex]h=32.5[/tex]
