Brad and Don went to the mall together. Brad spent $18 on food. Don spent twice the amount of money that Brad spent.
a) Write an algebraic equation to express how much Don spent and solve the equation you made.
b) Brad's sister had gone to the mall the day before and spent 30% of what Don did. How much did she spend?
c) If the tax rate was 13% how much of what Don and Brad spent was for tax?
Answer:
a). x=18x2
18x2=36
Don spent 36 dollars.
b). x=36x0.3
36x0.3=10.8
Brad's sister spent 10 dollars and 80 cents.
c). 36+18=54
1.0-0.13 = 0.87
54x0.87=46.98
54-46.98=7.02
Don and Brad paid 7 dollars and 2 cents in tax.

Find the measure of the central angle of an arc
with length 5n units and radius of 4.5 units.
Answer:
Theta = 10n/9 radians.
Step-by-step explanation:
The length is 5n units
Radius is 4.5 units
center angle is, S = r * theta
5n = 4.5 * theta
Theta = 5n/4.5
= 50n/45
= 10n/9

(trigonometry) solve for x
Answer:
[tex]x = 21 \sin(38 \degree) \\ x = 12.93[/tex]
The more accurate value is roughly x = 16.5482258257411
=====================================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(38) = x/21
21*cos(38) = x
x = 21*cos(38)
x = 16.5482258257411 which is approximate

-Chetan K
Answer:
x = 78
Step-by-step explanation:
The angle labeled x and the angle with a measure of 78° are vertical angles
Vertical angles are congruent ( equal to each other )
So if "x"'s vertical angle has a measure of 78 degrees than x also has a measure of 78 degrees.

Variable p is 2 less than variable d. Variable p is also 1 more than variable d. Which pair of equations best models the relationship between p and d? (5 points)
a
p = d + 2
p = d − 1
b
p = d − 2
p = d + 1
c
d = 2p
d = 2p − 1
d
d = 2p
d = 2p + 1
Answer:
b)
p = d − 2
p = d + 1
Step-by-step explanation:
From the above question:
Interpreting the statement above to form algebraic expressions, we have:
Variable p is 2 less than variable d.
Less than means to subtract in this context
p = d - 2
Variable p is also 1 more than variable d
More than means to add in this context
p = d + 1
Therefore, the pair of equations tha best models the relationship between p and d is Option b :
p = d − 2
p = d + 1

The Seventh Inning Stretch Company has created a new baseball that will improve your chances of hitting a home run. The 36-inch bat is only available online. To protect the bat, it must be shipped so the handle of the bat is in one corner of the box and the top portion of the bat touches the opposite diagonal corner.The shipping box has a length of 30 inches and a height of 6 inches. How wide should the box be to fit the 36-inch bat? Show and explain your work.
Answer:
Width of the box = 18.97 inches
Step-by-step explanation:
Length of the bat = 36 inches.
That means length of the diagonal of the bat (BC) = 36 inches
By applying Pythagoras theorem in right triangle BDC,
BC² = BD² + CD²
BC² = (30)² + w² -------(1)
BY applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
(36)² = 6² + BC²
By substituting the value of BC from equation (1),
(36)² = 6² + (30)² + w²
1296 = 36 + 900 + w²
w² = 1296 - 936
w = √360
w = 18.97 inches

Sara claims that a sequence of transformations carries Rectangle 1 onto Rectangle 2. Which of the following sequences of transformations can be used
to support Sara's claim?
A
a reflection over the y-axis, followed by a reflection over the x-axis.
B
a translation of 7 units to the left, followed by a translation of 8 units up.
С
a reflection over the x-axis, followed by translation of 4 units to the right
D
a rotation of 270° clockwise about the origin, followed by a reflection over the y-axis.
The sequences of transformations can be used to support Sara's claim that is A; a reflection over the y-axis, followed by a reflection over the x-axis.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs), etc.
Given that Sara claims that a sequence of transformations carries Rectangle 1 onto Rectangle 2.
When a graph is reflected along an axis, it says x-axis, then that leads the graph to go just to the opposite side of the axis as if we can see it in a mirror.
If we study it more, then we will find that it is symmetric, however, each point is equidistant from the axis of reflection as that of the image of that point.
Therefore, The sequences of transformations can be used to support Sara's claim that is A; a reflection over the y-axis, followed by a reflection over the x-axis.

Answer:
48
Step-by-step explanation:
Answer:
Average of 3mph
Step-by-step explanation:
If Sarah goes uphill at 2mph and downhill at 4mph.
Then to find the average you can:
Add 2 plus 4
which equals 6
Then divide the sum of 6 by the number of values given, there are two values (2 and 4)
6 divided by 2 equals 3
So the average is 3mph

Each backpack in a store is on sale for $5 off the original price. How does this affect the median price?
Answer:
this would cause the median price to go down by $5 as well.
Step-by-step explanation:
If every single backpack in the store is on sale, then this would cause the median price to go down by $5 as well. This is because the median price is the middle value in a data set. Therefore, if every backpack value drops by $5 then so does the backpack that has the middle value and is the median price of all the backpacks. This is the only actual effect that this sale will have to the median price of the backpacks.

Isabel is buying framing to go around the perimeter of one of her paintings. Each inch of framing costs $0.40. What is the total cost of the framing for the pantings
I have added the complete question. That is in the attachment
Answer:
$13.2
Step-by-step explanation:
Cost of 1 inch = $0.4
Perimeter of painting is same as perimeter of a rectangle since painting is a rectangle
Perimeter = 2(l+b)
L = 10¼
B = 6¼
P = 2(10¼ + 6¼)
P = 2(41/4 + 25/4)
P = 2(10.25 + 6.25)
P = 2(16.5)
P = 33
Total cost of framing
= 0.4 x 33
= $13.2
How do you calculate the Monthly Share of Annual Expenses? What would they be if the annual expenses were $27,987? (Show Your Work)
Answer:
$2332.25 per month
Step-by-step explanation:
1) The monthly share of annual expenses can be calculated from the annual expenses. Since there are 12 months in a year, the monthly share of annual expenses is gotten by dividing the annual expenses by the number of months in a year.
2) The monthly share of annual expenses is given by:
Monthly share of annual expenses = Annual expenses / 12 months
Monthly share of annual expenses = $27987 / 12 months = $2332.25 per month
