Greg sold his used electric saw and accessories for $759. If he received ten times as much
money for the electric saw as he did for the accessories, find how much money he received
for the electric saw.
Answer:
Step-by-step explanation:
Let the amount of money received for the accessories = x
Then the Saw would be 10x
The total is 10x + x = 759
11x = 759 Divide both sides by 11
x = 759 / 11
x = 69 dollars.
The saw was 10 times this amount = 10 * 69 = 690
Check
690 + 59 = 759
If gas costs $3.15 per gallon, how many whole gallons of gas could you buy with $27.00?
(Make sure to answer with a whole number.) just explain it
Answer: 8 whole gallons.
Step-by-step explanation: If you have only $27.00 and you need to buy gas, but each gallon is $3.15, then you just need to divide your total amount ($27.00) by your cost per gallon ($3.15), and you will get about 8.6 gallons, however this question asks for how many WHOLE gallons you can get, so all you need to do is round down to fit your budget, leaving money for only 8 whole gallons.
WORK: ($27.00) / ($3.15) = 8.6 gallons

if U=π (r+h),find the value of "r" when U=16 whole 1 upon 2 and h=2
Answer:
r = 3 1/4
Step-by-step explanation:
Here, we want to find the value of r given the values
Firstly, we will write r as the subject of the formula
U = π ( r + h)
U/π = r + h
r = U/π - h
Now substitute;
U = 16 1/2 = 33/2
h = 2
π= 22/7
r = 33/2/22/7 - 2
r = (33/2 * 7/22) - 2
r = 21/4 - 2
r = (21-8)/4
r = 13/4 = 3 1/4

The cost C in dollars of manufacturing x bicycles at a production plant is given by the function shown below.
C(x) = 3x^2- 600x + 43,500
a. Find the number of bicycles that must be manufactured to minimize the cost.
b. Find the minimum cost.
Answer:
Minimum 100 bicyclesMinimum cost is 13500Step-by-step explanation:
Given function:
C(x) = 3x^2- 600x + 43500a.
Minimum cost is obtained at vertex.
Vertex is determined by formula x = -b/2a, in standard form of
f(x) = ax^2 + bx + c
Vertex of the given function is:
x = -(-600)/(2*3) = 100b.
Cost at vertex is:
C(100) = 3*100^2 - 600*100 + 43500 = 13500What is 55 times 66 divied by 45

3. Consider this dilation Complete sentences
(a) is the image of the dilation a reduction or an enlargement of the original figure? Explain
(b) What is the scale factor? Explain
Answer
Answer:
a) A reduction
b) The scale factor is 1/2
Step-by-step explanation:
The vertices of the original figure, ABCD are;
A(-2, 4), B(4, 4), C(2, -2), and D(-4, -2)
The vertices of the image, A'B'C'D' are;
A'(-1, 2), B'(2, 2), C'(1, -1), and D'(-2, -1)
a) The length of the side AB = 4 - (-2) = 6 (Distance between points having the same 'x' or 'y' coordinates
The length of the side A'B' = 2 - (-1) = 3
The length of AB = 6 is larger than the length of A'B' = 3, therefore the image A'B'C'D' is a reduction of (is smaller) the figure ABCD
b) The scale factor = The ratio of the lengths corresponding sides of the image to the original figure;
∴ The scale factor =A'B'/AB = A'D'/AD = B'C'/BC = D'C'/DC
AD = √((-4 - (-2))² + (-2 - 4)²) = 2·√10
A'D' = √((-2 - (-1))² + (-1 - 2)²) = √10
A'D'/AD= √10/(2·√10) = 1/2
Therefore, given that the coordinates of the preimage are 2 × the coordinates of the image, we have;
The scale factor = A'B'/AB = B'C'/BC = D'C'/DC = A'D'/AD =1/2
The scale factor is 1/2, therefore, we multiply the dimensions of the original figure by 1/2 to get the dimensions of the image.
The scale factor = 1/2.

The product of two rational numbers is irrational.
Answer:
The statement is false.
Step-by-step explanation:
Here we need to remember some things:
Integer numbers are closed under multiplication.
This means that for two integers a and b, the product a*b is also an integer.
A rational number is a number that can be written as the quotient of two integer numbers.
An irrational number is a number that can't be written as the quotient of two rational numbers.
Now let's see the statement:
"The product of two rational numbers is irrational."
The product of two rational numbers is written as:
[tex]\frac{a}{b} *\frac{c}{d}[/tex]
Where a, c, b, and d are integers.
We can rewrite that product as:
[tex]\frac{a*c}{b*d}[/tex]
Because of the first property, we know that a*c is an integer, and b*d is also an integer, so here we have a quotient of two integer numbers, so this is a rational number.
Then the product of two rational numbers is a rational number.
Then the statement is false.
can someone please help me solve this?

Alexandria wants to go hiking on Saturday. She will consider these conditions when she chooses which of several parks to visit:
• She wants to hike for 2 hours.
• She wants to spend no more than 6 hours away from home.
• She can average 65 miles per hour to and from the park.
Write and solve an inequality to find possible distances from Alexandria’s home to a park that satisfies the conditions.
A. 392 miles
B. 260 miles
C. 16 miles
D. 392 miles
Answer:
B. 260 miles
Step-by-step explanation:
The important thing to consider here is the maximum amount of time she can spend driving. Since she will spend 2 hours at the park and want to be gone no more than 6 hours, this number is 4 hours.
This means she can spend 2 hours on the way to the park and 2 hours back. Her maximum distance, therefore, is 2 hours times an average speed of 65 miles per hour
Therefore:
2x ≤65 * 4
2x ≤ 260
x ≤ 130
Her maximum distance is 2 hours x 65 mph = 130 miles.
Answer:
Alexandria can choose any distance not more than 130 miles from her house to the park.
Step-by-step explanation:
Let Alexandria takes time 't' hours to walk from home to the park and distance between park and home is 'x' miles.
If she averages 65 miles per hour "to and fro" from her home to the park then the inequality that will represent this situation will be
2x ≤ 65t [ Distance = Speed × time ]
If she wants to hike for 2 hours and maximum time spent to reach the park is 6 hours
Then the maximum time spent by her to reach the park from her home should be = 6 - 2 = 4 hours.
By placing the value of t = 4 in the inequality
2x ≤ (65×4)
2x ≤ 260
x ≤ 130
Therefore, Alexandria can choose any distance not more than 130 miles from her house to the park.
Alexandria wants to go hiking on Saturday. She will consider these conditions when she chooses which of several parks to visit: • She wants to hike for 2 hours. • She wants to spend no more than 6 hours away from home. • She can average 65 miles per hour to and from the park. Write and solve an inequality to find possible distances from Alexandria’s home to a park that satisfies the conditions.
The actual answer is 180 miles if anyone was wondering. I know the other answer is "Verified" but its wrong. me and the other people who trusted it know that. good luck.
Alexandria wants to go hiking on Saturday. To choose from several parks she could go to, she considers these conditions.

Explain show work please.
Favorite Answer
The distance from Alexandria's home to a park has to be within 130 miles.
Let h = time of Alexandria's hike = 2 hours.
Let p = time spent to get to park (driving)
h + 2p (since it is round trip - to the park and back) <= 6 hours (time to spend away from home)
h = 2, thus
2 + 2p <= 6
2p <= 4
p <= 4/2 = 2
Thus, she has to spend 2 hours to get to the park, and spend 2 hours to get back home.
distance to the park <= speed of driving x time of getting to park
<= 65 miles per hour x 2 hours
<= 130 miles
Thus, we get the 130 miles.
The correct option is B. 260 miles. and the required inequality is [tex]2+\dfrac{D}{65} \leq 6[/tex].
Given, Alexandria wants to go hiking based on the conditions.
The average speed of Alexandria is 65 miles per hour.
Since she wants to hike minimum of 2 hours, so minimum distance covered by her will be [tex](65\times2=130) \\[/tex] miles.
Now time [tex]t[/tex] required to cover [tex]D[/tex] distance with the speed of 65 miles per hour will be [tex]\frac{D}{65}[/tex] hours.
But She doesn't want to spend more than 6 hours away from home,
So the inequality becomes,
[tex]2+\dfrac{D}{65} \leq 6[/tex].
On solving for D,
[tex]\dfrac{D}{65} \leq 6-2[/tex]
[tex]D\leq 4\times65\\\\\D\leq 260[/tex]
Hence the Distance traveled by Alexandria must not exceed by 260 miles.
Therefore the correct option is B. 260 miles. and the required inequality is [tex]2+\dfrac{D}{65} \leq 6[/tex].

That's the only equation that if x = 0, y will = 0
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
A
y = x + 1 ← has a y- intercept of 1
B
y = x - 1 ← has a y-intercept of - 1
C
y = 2x ← has a y- intercept of 0
D
y = 2x + 2 ← has a y- intercept of 2
Thus y = 2x passes through the origin → C
