Answer:
$12.54
Step-by-step explanation:
First, you have to apply the sale to the original price. In this case, you would have to multiply 22 and 43% to get $9.46. Now, you have to subtract 9.46 from 22 to get 12.54.
Select the correct answer. Which transformation will always map a parallelogram onto itself? A. a 90° rotation about its center B. a reflection across one of its diagonals C. a 180° rotation about its center D. a reflection across a line joining the midpoints of opposite sides
Answer:
C. a 180° rotation about its center
Step-by-step explanation:
The question is on rotation of an object about the origin through 180°
When a point B, (h,k) is rotated about the origin 0 through 180° both clockwise and anticlockwise directions , the new position is B'(-h,-k)
Example, if we have point K (5,8) rotated through 180°, clockwise or anti-clockwise about the origin the new position will be; K'(-5,-8)
A 180° rotation about the center of a parallelogram will always map the parallelogram back onto itself due to the shape's symmetry.
Explanation:The transformation that will always map a parallelogram onto itself is a 180° rotation about its center. This is because a 180° rotation essentially flips the shape over, but, because a parallelogram is symmetrical, it would still look the same. For example, imagine a parallelogram ABCD with point A at the top and AB as the base. If you rotate it 180°, point A was at the top and now is at the bottom, but the shape is still a parallelogram. Similarly, the other transformations may not necessarily map the shape back onto itself.

what is equivalent to 4 feet
Final answer:
4 feet is equivalent to 1 1/3 yards or 48 inches, as there are 3 feet in a yard and 12 inches in a foot.
Explanation:
The student has asked what is equivalent to 4 feet. To answer this, we must understand that feet and yards are units of measurement commonly used to measure length or distance. In the United States customary system, 1 yard is equivalent to 3 feet. Therefore, to find the equivalent of any number of feet in terms of yards, one can divide the number of feet by 3. For 4 feet, this would be calculated as follows:
4 feet ÷ 3 feet/yard = 1 1/3 yards.
Alternatively, since 4 is just 1 more than 3, we can see that 4 feet is 1 yard plus 1 additional foot, which confirms our conversion of 1 1/3 yards. Other times, feet may be converted into inches, where 1 foot equals 12 inches. In this case, 4 feet x 12 inches/foot equals 48 inches.
3. A city planner is measuring the distance of one city block. Which unit of measure should she use: 1 mile, 1 meter, 1/2 inch?
Meter :) hope this helps!
Answer:
Meters
Step-by-step explanation:
City planner should use Meter unit as the distance within the city blocks are much higher that the distances which can be measured in inches and they are much lesser than the distances which can be measured in Miles.
For instance, Two blocks of a city can not be few miles away or few inches away , but they can be few meters away from each other.

Jamie says the value of the expression 1.43 ×(-24/47) is close to −0.75. Does Jamie's estimate seem reasonable? Explain.
Answer:
The estimate is reasonable.
Step-by-step explanation:
Jamie's estimate seems reasonable.
We can see that there is (-24/27) in the bracket, first of all there is negative sign so there will be negative sign in the answer. Moreover, 24 is near to half of 27 so fraction will result in -0.5XXXXX and multiplying it with 1.4 will increase it around -0.75.
We can solve the given fraction for confirmation,
So,
[tex]= 1.43 * (\frac{-24}{47} )\\=1.43*(-0.5106)\\=-0.7302[/tex]
which is near to -0.75 so the estimate of Jamie was right ..
Jamie's estimate of -0.75 is reasonable given the calculated result of approximately -0.73.
The value of the expression 1.43 × (-24/47) is indeed close to -0.75. To show this, let's calculate it step by step:
Multiply 1.43 by -24: 1.43 * -24 = -34.32Now, divide -34.32 by 47: -34.32 / 47 ≈ -0.7298Therefore, Jamie's estimate of -0.75 is reasonable given the calculated result of approximately -0.73.
4.5kg of oranges and 3kg of apples cost a total of £3.87 2.5kg of oranges cost £1.40 Work out the cost of 1kg of apples.
Final answer:
The cost of 1kg of apples is £0.45, calculated using two equations derived from the given information about the cost of oranges and apples.
Explanation:
To work out the cost of 1kg of apples, we can set up two equations based on the information given: 4.5kg of oranges and 3kg of apples cost a total of £3.87, and 2.5kg of oranges cost £1.40. Let's assume the cost per kilogram of oranges is 'O' and the cost per kilogram of apples is 'A'. The equations would be:
4.5O + 3A = 3.87 ........(1)
2.5O = 1.40 ........(2)
From equation (2), we can calculate the cost of oranges per kilogram:
O = 1.40 / 2.5
O = £0.56 per kilogram
Now substitute the value of 'O' in equation (1) to find 'A':
4.5(0.56) + 3A = 3.87
2.52 + 3A = 3.87
3A = 3.87 - 2.52
3A = 1.35
A = 1.35 / 3
A = £0.45 per kilogram
Therefore, the cost of 1kg of apples is £0.45.
Travis is buying Mushrooms at the grocery store mushrooms cost five dollars for 9 ounces how much will 13 ounces of mushroom cost to the nearest cent

What is the next term in the geometric sequence -1 -2 -4
Answer:
-8
Step-by-step explanation:
r=2
so multiply third term by 2
Answer: -8
Step-by-step explanation:
We must remember that, in geometric sequences, the ratio between the consecutive terms is constant.This is called "Common ratio" and is represented with "r".
We need to find the common ratio of this geometric sequence:
Divide one term by the previous term:
[tex]r=\frac{-4}{-2}\\\\r=2[/tex]
Then, the next term asked in the exercise can be found by multiplying -4 by 2.
Therefore, this is:
[tex]next\ term=(-4)(2)\\\\next\ term=-8[/tex]

If the bank charges Dominic an overdraft fee of $25 every time he overdraws his account, and Dominic overdrew his account on Thursday but not on Saturday, which of the following is a possible amount of money that Dominic could have had in his account last Sunday? Assume that the only debits and credits not listed are overdraft fees.
a.
$500
b.
$480
c.
$435
d.
$400
Please select the best answer from the choices provided
A
B
C
D
Answer:
THE ANSWER IS C.435
Step-by-step explanation:
Answer:
The correct answer would be option C, $435
Explanation:
In real financial banking transactions, Debits are basically the withdrawals and credits are deposits.
Because the problem states that there was an over withdrawal on Thursday but not on Saturday, this means that the ending balance on Thursday was a negative balance. On Saturday, the remaining balance was a positive balance. 500 and 480 as a beginning balance doesn't give a negative balance on Thursday. 400 as a beginning balance gives a negative balance on Thursday as well as Saturday.
Debit Credit Balance
Sunday 435
Monday 158 277
Tuesday 69 44 252
Wednesday 175 77
Thursday 131 38 -16
25 -41 Overdraft fee
Friday 53 12
Saturday 22 14 4
So the correct answer is option C, $435

Solve 30/m+1=10/3m-5
Show work
30(3m-5)=10(m+1);
90m-150=10m+10;
90m-10m=150+10;
80m=140;
m=140/80=14/8=1.75
Answer:
m = 2
Step-by-step explanation:
If you're dividing 10 by 3m-5, please enclose the 3m - 5 inside parentheses to eliminate any ambiquity:
Solve 30/(m+1) = 10/(3m-5)
Here we have the LCD (m+1)(3m-5). Multiply both sides of this equation by this LCD and simplify the results:
30 10
(m+1)(3m-5)--------- = (m+1)(3m-5)----------
m+1 3m-5
After cancelling, we have:
30(3m-5) = 10(m+1),
which, when expanded, comes to:
90m - 150 = 10 m + 10
Combining like terms, we get:
80m = 160, and so m = 2.

heart beats.
Use it to estimate how many times the patient's heart will beat in 18 minutes. Write an
equation in Y = mx + b form.,
Answer:
1440 beats
Step-by-step explanation:
Given that a doctor measured a patient's resting pulse rate at 80 beats per minute.
i.e. if no of beats in a dependent variable on time then we have a linear relationship between y - no of beats and x - no of minutes
Here slope= rate of change of y with respect to x [tex]= m=80[/tex]
And we have y intercept as 0 since when time is 0 no heart beat. i.e. (0,0) is a point on the line
The equation would be
[tex]y=80x[/tex],x≥0
When [tex]x=18, \\y = 18(80)\\y = 1440[/tex] beats.

m BC= 30°
m2 =

80
100
Answer:
∠2 = 80°
Step-by-step explanation:
Since BD is a diameter then
∠1 + ∠2 = 180°, that is
100° + ∠2 = 180° ( subtract 100° from both sides )
∠2 = 180° - 100° = 80°
Answer:
B. 80
Step-by-step explanation:
We have been given a circle. We are asked to find the measure of angle 2.
Since BD is diameter of our given circle, so angle 1 and angle 2 will be linear pair of angles.
We know that linear angles add up-to 180 degrees, so we can set an equation as:
[tex]m\angle 1+m\angle 2=180^{\circ}[/tex]
[tex]100^{\circ}+m\angle 2=180^{\circ}[/tex]
[tex]100^{\circ}-100^{\circ}+m\angle 2=180^{\circ}-100^{\circ}[/tex]
[tex]m\angle 2=80^{\circ}[/tex]
Therefore, measure of angle 2 is 80 degrees and option B is the correct choice.
