Maggie is converting 10,560 feet to miles by using StartFraction 10,560 feet Over 1 EndFraction times StartFraction 1 mile Over 5,280 feet EndFraction. What should be Maggie's answer?
Answer:
2miles
Step-by-step explanation:
Using the conversion factor for converting feet to miles
1 mile = 5280feet
We are to convert 10560feet to miles, we will say
x miles = 10560feet
Equating both expressions
1 mile = 5280feet
x miles = 10560feet
Cross multiply
5280x = 10560
Multiply both sides by 1/5280
5280x × 1/5280 = 10560 × 1/5280
x = 10560/5280
x = 2
Hence Maggie's answer should be 2miles

Roshaun has saved $150 and continues to add $10 each week. Keegan starts with $0 and saves $25 each week. In how many weeks will they have the same amount of money?
Answer:
10 weeks
Step-by-step explanation:
Total difference in money = $150 - $0
= $150
Difference per week = $25 - $10
= $15
No. of weeks = $150 ÷ $15
= 10
They will have the same amount of money after 10 weeks.
What is equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
Given that, Roshaun has saved $150 and continues to add $10 each week. Keegan starts with $0 and saves $25 each week.
Let the number of weeks for amount being same be x,
150 + 10w = 0 + 25w
150 = 15w
w = 10
Hence, They will have the same amount of money after 10 weeks.

Hi there.
The answer is g(1) = 3
Explanation:
Find the function that has x = 1 as a part of the domain. That is the second function that has x = 1 as a part of domain.
For the first function, the domain is lesser than or equal to -1, therefore, x = 1 isn't the part.
For the third function, the domain is greater than or equal to 2, meaning x = 1 isn't also the part of the domain as well. That leaves only the second function where -1 < x < 2 as x = 1 is the part.
Thus, our main function is —
[tex]g(x) = 3[/tex]
Then evaluate the value of g(x), substitute x = 1 in the equation. However, the function doesn't have x-term.
Thus, answer the constant number.
Therefore,
[tex]g(1) = 3[/tex]

One of the sides of a parallelogram has the length of 5 in. Can the lengths of the diagonals be 4 in and 3 in?
Answer:
Answer: Yes, the diagonals could be 6 and 7 in. In a parallelogram, only the opposite sides of the parallelogram are congruent.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
1. What one needs to know
In a parallelogram, the diagonals bisect.
Triangles sides inequality, the sum of the smaller two sides in a triangle, must be greater than the measure of the larger side in that triangle.
2. Applying this knowledge
It is given that the diagonals are 4in and 3inches. Since diagonals bisect, the length of the sides of the formed triangle would be; 2in and 1.5in. If one adds these two numbers, one gets 3.5in. 3.5in is less than 5in, hence, a triangle can't have a side length of 5, and diagonals with the length of 3in and 4 in.

Triangle DOG is similar to triangle CAT. In triangle CAT, angle C is 81 degrees and angle A is 67 degrees. Determine the measure of angle G.
A. 148 degrees
B. 81 degrees
C. 67 degrees
D. 32 degrees
Answer:
D. 32 degrees
Step-by-step explanation:
First you must know that the sum of angle in a triangle is 180. Hence in triangle CAG;
<C + <A+ <T = 180
Given
<C = 81 degrees
<A = 67 degrees
Substitute
Get <T first
81 + 67 + <T = 180
148 + <T = 180
<T = 180 - 148
<T = 32 degrees
Since Triangle DOG is similar to triangle CAT, then <T = <G = 32 degrees
Hence the measure of <G is 32 degrees

Answer:
Not Linear
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be
0
or
1
for each of its variables. In this case, the degree of variable
y is 1, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.
Two students are going to the store to buy school supplies for the new school year. One of the students buys 2 packs of pencils and 3 packs of pens for $8.25. Her friend purchases 5 packs of pencils and 2 packs of pens for $11.00. Is there enough information to determine the cost of 1 pack of pencils and 1 pack of pens? Explain why or why not.
Answer:
Yes, it's enough information
Step-by-step explanation:
yes, there is enough information to determine the cost of 1 pack of pencils and 1 pack of pens
we just need an algebra of elimination and substition to find the coat of each. like this:
pencils = C
pen = N
2 C + 3 N = 8.25 (times by 2)
5 C + 2 N = 11.00 (times by 3)
------------------------- - (we eliminate the N)
4 C + 6 N = 16.50
15 C + 6 N = 33.00
------------------------- -
-11 C = - 16.5
C = (-16.5) : (-11) = $ 1.50
so the price of 1 pack of pencils is $ 1.50
now we use subtitution to find the price of 1 pack of pens
2 C + 3 N = 8.25
2 (1.50) + 3 N = 8.25
3.00 + 3 N = 8.25
3 N = 8.25 - 3.00
3 N = 5.25
N = 5.25 : 3 = $ 1.75
so the price of 1 pack of pencils is $ 1.75
