A parallelogram has one angle that measures 18°. What are the measures of the other three angles in the parallelogram? °, °, and °
The angels of parallelogram is 162, 18, 162 and 18.
How to find the measures of the other three angles in the parallelogram?given that A parallelogram has one angle that measures 18° means one angle is 18°
we know that
A special variety of quadrilateral called a parallelogram has two sets of opposite sides that are parallel and equal.
The sum of all the angels of parallelogram is equal to 360°
so, the other means second angle of parallelogram is 18°
Let us assume the 3rd be x.
then the 4th also be x, because the opposite sides are equal.
now sum of all angles is 360°
then x + 18 + x + 18 = 360
2x + 36 = 360
2x = 360 - 36
x = 162.
so the 3rd and 4th angles are 162°.
Hence the angels of parallelogram is 162, 18, 162 and 18.

From a 24-cm by 24-cm piece of cardboard, square
corners are cut out so that the sides can be folded up
to make a box. Complete parts a through c below.
a) Express the volume of the box as a function of the side x, in centimeters, of a cut-out square.
Answer:
V(x) = 4x³ - 96x² + 576xStep-by-step explanation:
Cut out square on each corner has side of x.
When folded up the height of the box becomes same as the side of the cut-out square.
Sides of the base of the box are:
24 - 2x cm as it is folded on both sides.The volume of the box which is the right square prism is:
V = Bh = a²h, where B- base area, a- side of the base, h- height.Substitute the values and find the volume:

Find the unknown quantity in the following percent problem using the formula R⋅B=A. Round your answer to two decimal places, if necessary. % of 140 is 717.
The unknown quantity is 512.14 percent, that is 512.14% of 140 is 717
According to the question the formula that we have to use is
R*B = A (1)
And we have been given that
x% of 140 = 717 (2)
Thus we have to find the x percent. Comparing equation (1) and (2) we get,
R = x%
B = 140
A = 717
Therefore to find the value of R we will use the formula, R = A/B
Thus, x% = 717/140
x % = 5.12
x = 512.14
Hence the unknown quantity is 512.14 percent that is, 512.14% of 140 is 717

A worker in the United States can produce 50 cell phones in a week, and a worker in China can produce 100 cell phones in a week. Answer the following questions based on this information. Part A: If each country attempted to produce both jeans and cell phones, how many jeans and cell phones could each country produce? What would be the total number of jeans and cell phones produced by the two countries combined? (Show your work.)
The jeans and cell phones produced by US will be 500 and 25 and jeans and cell phones produces by china will be 500 and 50 and the total number of jeans and cell phones is 1000 and 75.
Given that worker in the United States and a worker in China can each produce 1,000 pairs of jeans per week and A worker in the United States can produce 50 cell phones, and a worker in China can produce 100 cell phones in given time.
US: opportunity cost of jeans = 50/1000= 0.05;
1Jeans = 0.05 cell phones
China: opportunity cost of jeans = 100/1000= 0.1
1 jeans= 0.1cell phones
US: opportunity cost of cell phones= 1000/50= 20
1 cell phone= 20 jeans
China: opportunity cost of cell phones = 1000/100= 10
1 cell phone = 10 jeans
Each country will give equal time for producing each product.
Thus, each firm will produce half of its capacity when they combined there production.
So, pair of jeans US will produce in a week 1000/2 = 500 pair jeans a week
Cell phones US will produce in a week 50/2 = 25 cell phones in a week.
Similarly, pair of jeans china will produce in a week 1000/2 = 500 pair jeans a week
& Cell phones china will produce in a week 100/2 = 50 cell phones in a week.
The total number of jeans produced by the two countries combined is
500+500=1000
The total number of cell phones produced by the two countries combined is 25+50=75.
Hence, The jeans and cell phones produced by US will be 500 and 25 and jeans and cell phones produces by china will be 500 and 50 and the total number of jeans and cell phones is 1000 and 75 when United States and a worker in China can each produce 1,000 pairs of jeans per week.

Answer: The Function of g(x) = k[f(x)] = k |x|
Following these rules we can define a vertical stretch or compression of any function.
Step-by-step explanation:
When a function of absolute values, f, is stretched or contracted vertically,
Define f(x) :
f(x) is the value of the function. m is the slope of the line. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane. x is the value of the x-coordinate.
Define g(x) :
The function g (x) is called an inner function and the function f (x) is called an outer function.
When the vertical component of a function f(x) = |x| is increased by a factor k,
g(x) = k[f(x)] = k |x|
where k > 1,
If the same function is compressed vertically by a factor k,
g(x) = k[f(x)] = k |x|
where 0 < k < 1,
Following these rules we can define a vertical stretch or compression of any function.

The difference two positive integer is 3. If the smaller is added to the square of the larger the sun is 417 find the integers
Answer:
[tex]17[/tex] and [tex]20[/tex].
Step-by-step explanation:
Let [tex]x[/tex] denote the larger one of the two positive integers ([tex]x > 0[/tex].) The smaller integer would be [tex](x - 3)[/tex]. The square of the larger integer would be [tex]x^{2}[/tex].
The sum of the smaller integer and the square of the larger integer is [tex](x^{2} + (x - 3))[/tex]. If this sum is equal to [tex]417[/tex], then:
[tex]x^{2} + x - 3 = 417[/tex].
[tex]x^{2} + x - 420 = 0[/tex].
Solve this quadratic equation for [tex]x[/tex] through factorization. Since [tex]420 = 21 \times 20[/tex]:
[tex]x^{2} + x - (21 \times 20) = 0[/tex].
[tex]x^{2} + 21\, x - 20\, x + (21)\, (-20) = 0[/tex].
[tex](x + 21)\, (x - 20) = 0[/tex].
Thus, either [tex]x = 20[/tex] or [tex]x = (-21)[/tex] by the Factor Theorem. However, since [tex]x > 0[/tex] (the two integers are both positive,) only [tex]x = 20[/tex] is a valid solution.
Hence, the larger one of the two integers would be [tex]20[/tex]. The smaller one of the two integers would be [tex](x - 3) = (20 - 3) = 17[/tex].

And since there is no B there it's only going to be considered zero
I hope iv been of help to you ^w^

The measures of angle ACB and angle ABC are 40° and 63° respectively
How to determine the valueFrom the information given, we have that angle DAB is on a straight line
But angle D is 103°
Remember that angles on a straight line sum up to 180°
Then,
103° + Angle A = 180°
Angle A = 180 - 103
Angle A = 77°
It is important to note that sum of angles in a triangle is 180°
angle ACB + angle ABC + angle CAB = 180°
Where;
angle ACB = 3x - 14angle ABC = 3x + 9angle CAB = 77°Substitute into the formula
3x - 14 + 3x + 9 + 77 = 180
collect like terms
3x + 3x = 180 - 72
6x = 108
Make 'x' the subject
x = 108/6
x = 18
But;
Angle ACB = 3x - 14 = 3(18) - 14 = 54 - 14 = 40°
Angle ABC = 3x + 9 = 3(14) + 9 = 54 + 9 = 63°
Thus, the measures of angle ACB and angle ABC are 40° and 63° respectively.

Mia took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.30 plus $4.25 per mile. The total fare was $31.05, not including the tip. How many miles was the taxi ride?
The taxi ride was 7 miles
How to calculate the number of miles ?Mia took a taxi from her house to the airport
The taxi charged a pick up fee of $1.30
They also charged $4.25 per mile
The total fare was $31.05
The number of miles can be calculated as follows
31.05 - 1.30 = 4.25x
29.75= 4.25x
Divide both sides by the coefficient of x which is 4.25
29.75/4.25= 4.25x/4.25
x= 7
Hence the taxi ride was 7 miles
