Answer:
Step-by-step explanation:
since there is no given formula I'm guessing that's what we want to find?
use the dist. = rate * time formula for this kind of problem
or d = r*t ( this looks like the word "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt :P )
so Jean's rate is 64 MPH
her total distance is 448 miles
rearrange the d = rt formula so that you are solving for the thing you don't know.. yet.... t (time) for this case
soooo...
d/r = t
plug in number
448 / 64 = t
7 = t (in hours)
what is the simplified form of 4x - 7 + x - 10
Answer:5x-17
Step-by-step explanation:
4x - 7 + x -10 = 0
4x + x - 7 - 10 = 0
5x - 17 = 0
5x = 17
x = 17/5

Step-by-step explanation:
A florist can order roses in bunches of 12 and lilies in bunches of 8. Last month she ordered the same number of roses and lilies. If she ordered no more than 100 of each kind of flower, how many bunches of each could she have ordered? Find all the possible combinations.
Answer:
2 bunches of roses and 3 bunches of lilies.
4 bunches of roses and 6 bunches of lilies.
Step-by-step explanation:
Given that:
Roses come in a bunch of 12 flowers and
Lilies come in a bunch of 8 flowers
Number of roses ordered is equal to the number of lilies ordered.
Total number of flowers ordered are lesser than 100.
To find:
The possible number of combinations such that equal number of flowers are bought.
Solution:
Here, we need to find the Least Common Multiple.
[tex]12 = \underline{2 \times 2} \times 3[/tex]
[tex]8 = \underline{2 \times 2} \times 2[/tex]
LCM = [tex]2\times 2 \times 3 \times 2 = 24[/tex]
Therefore, we need to find the number of bunches such that number of flowers of each type bought are equal to LCM or multiples of LCM.
i.e.
24, 48, 72, 96 ....
Here, two types of flowers are there.
Therefore, 24 of each type, total 48 flowers i.e. 2 bunches of roses and 3 bunches of lilies.
48 of each type, total 96 flowers i.e. 4 bunches of roses and 6 bunches of lilies.
Total possible combinations:
2 bunches of roses and 3 bunches of lilies.
4 bunches of roses and 6 bunches of lilies.

Find the highest common factor (HCF) of 90 and 48.
Answer:
The answer is 6
Step-by-step explanation:
The highest common factor between the numbers is 6.
What is the greatest common factor?The greatest common factor is the largest positive number which can be divided into given numbers evenly.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two numbers are 90 and 48. The highest common factor will be calculated as,
90 = 2 x 3 x 3 x 5
48= 2x2x2x2x3
The common numbers are 2 x 3 = 6
Therefore, the highest common factor between the numbers is 6.

Ricky draws a square . He claims that any rotation about the center of the square that is a multiple of 30 degrees will carry the square onto itself . Which statement best describes Ricky's claim ?
Answer:
Option (a)
Step-by-step explanation:
This question is incomplete without statements; find the statements as followed,
a). Ricky's claim is incorrect since not all rotations that carry a square onto itself are multiples of 30 degrees.
b). Ricky's claim is incorrect since not all rotations that are multiples of 30 degrees carry a square onto itself.
c). Ricky's claim is correct since any rotation that carries a square onto itself is a multiple of 30 degrees.
d). Ricky's claim is correct since any rotation that is a multiple of 30 degrees carries a square onto itself.
Square ABCD will map onto itself when point A comes to B, C or D by a rotation about the center E with a multiple of measure of angle AEB.
m∠AEB = 90° [Diagonals of a square intersect each other at 90°]
In simpler words, if square ABCD is rotated 90° or it's multiple about the center E, square will overlap itself.
Therefore, Option (a) is correct.
Liam bought 2 vintage movie posters, 2 rock posters, and 1 rap poster. He applied a $35 gift card to the total purchase and a 1/2-off coupon to the rap poster. Write and evaluate a numerical expression to show how much Liam paid for the posters.
Vintage Movie: $28.50
B Movie: $18.25
Rock: $29.75
Rap: $19.50
Answer:
the vintage movie posters and the 2 rock posters could be priced the same, $8.
8 x 4 = 32.
the rap poster could be $6, but with the half-off coupon it comes to $3
32 + 3 = 35
assuming the gift card covers the total cost, this reasoning is correct.

Answer:
10. y=-4x+3
12. y=[tex]\frac{1}{2}[/tex]x+3
Step-by-step explanation:
In order for a line to be perpendicular to another, their slopes must be opposite reciprocals.
1. Put the given equations into slope-intercept form. (y=mx+b)
2. Identify the opposite reciprocal of the original equations. (#10: -4 & #12: [tex]\frac{1}{2}[/tex])
3. Plug your given coords and opposite reciprocals into point-slope formula (y-y₁=m(x-x₁)) and simplify the expression to get your equation of the line.
on the first day of your garage sale, you earn 12x+9 dollars. The next day you earn 22x dollars. Is it possible that you earned the same amount each day? Explain.
Set the two expressions equal to one another and solve for x
22x = 12x+9
22x-12x = 9
10x = 9
x = 9/10
x = 0.9
Assuming x is the number of items sold, then it is not possible to have the same amount earned for the two days. This is because we cannot sell 0.9 of an item. So it appears it is not possible to earn the same amount each day.

how does the graph of y=|x|+ 4 compare to the graph of the parent function y=|x|?
Answer:
Please check the explanation and attached graph.
Step-by-step explanation:
Given the parent function
y = |x|
In order to translate the absolute function y = |x| vertically, we can use the function
g(x) = f(x) + h
when h > 0, the graph of g(x) translated h units up.
Given that the image function
y=|x|+4
It is clear that h = 4. Since 4 > 0, thus the graph y=|x|+4 translated '4' units up.
The graph of both parent and translated function is attache below.
In the graph,
The blue line represents the parent function y=|x|.
The red line represents the image function y=|x| + 4.
It is clear from the graph that the y=|x| + 4 translated '4' units up.
Please check the attached graph.
A day can be evenly divided into 86,400 periods of 1 second; 43,200 periods of each 2 seconds; or in many other ways. In total, how many ways are there to divide a day into periods of seconds, where and are positive integers
Answer:
96 ways
Step-by-step explanation:
Given
[tex]Day = 86400\ seconds[/tex]
Required
Ways to divide it into period of seconds
What this question implies is to determine the total number of factors of 86400
To start with, we determine the prime factorization of 86400
To do this, we continually divide 86400 by 2; when it can not be further divided, we divide by 3, then 7, then 11...
[tex]86400/2 = 43200[/tex]
[tex]43200/2=21600[/tex]
[tex]21600/2=10800[/tex]
[tex]10800/2=5400[/tex]
[tex]5400/2= 2700[/tex]
[tex]2700/2 = 1350[/tex]
[tex]1350/2=675[/tex]
[tex]675/3=225[/tex]
[tex]225/3=75[/tex]
[tex]75/3=25[/tex]
[tex]25/5=5[/tex]
[tex]5/5 = 1[/tex]
This implies that:
[tex]86400 = 2^7 * 3^3 * 5^2[/tex]
The number of factors d is the solved by:
[tex]d = (a+1)*(b+1) *(c+1)[/tex]
Where
[tex]n = 2^a * 3^b * 5^c[/tex]
By comparison:
[tex]a = 7[/tex]
[tex]b = 3[/tex]
[tex]c=2[/tex]
So:
[tex]d = (7+1)*(3+1) *(2+1)[/tex]
[tex]d = 8*4 *3[/tex]
[tex]d = 96[/tex]
Hence, there are 96 total ways

pls answer
Answer:
110
Step-by-step explanation:
lets assume y is the angle next to x which should complete to form a 360.
50 + 25 + 35 + y = 360
y = 250
x + y = 360
x + 250 = 360
x = 110
Answer:
110
Step-by-step explanation:
lets assume y is the angle next to x which should complete to from a 360.
50 + 25 + 35 + y = 360
y = 250
x + y = 360
x + 250 = 360

( 6,1), (6,2 )( 6,3), (6,4) , (6,5),(6,6)}
The favourable cases
n(E) = {(1,2),(1,3),(1,4),(1,5),(1,6),(2,3),(2,4),(2,5),(2,6),(3,4),(3,5),(3,6),(4,5),(4,6),(5,6)} = 15

20/12=15/x find x plz help
Answer:
[tex]x = 9[/tex]
Step-by-step explanation:
To find x, we first have to solve the equation given in the question:
[tex]\frac{20}{12} = \frac{15}{x}[/tex]
[tex]20x = 15 \cdot 12[/tex]
[tex]x = \frac{180}{20}[/tex]
[tex]x = 9[/tex]
Therefore, x = 9.
Hope this helped!
Answer:
x=9
Step-by-step explanation:
We have: [tex]\frac{20}{12}[/tex]=[tex]\frac{15}{x}[/tex]
First, we can simplify 20/12 by 4
[tex]\frac{5}{3}[/tex]=[tex]\frac{15}{x}[/tex]
this is a proportion, so we can cross multiply (multiply 5 by x and 3 by 15)
5x=45
divide by 5
x=9
